Description

Technical Field

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

[0002] With the continuous development of electromechanical and electrical equipment, the industry is increasingly demanding higher precision in the processing of various components of such equipment. Current production equipment typically incorporates positioning mechanisms to improve product positioning accuracy and facilitate high-precision processing.

[0003] Traditional positioning mechanisms typically include multiple moving elements, resulting in complex structures and large space requirements. Utility Model Content

[0004] Therefore, it is necessary to provide a detection device to address the above-mentioned problems.

[0005] This application provides a detection device, which includes a base, a detection module, a positioning component, and a transfer component. The detection module is disposed on the base. The positioning component includes a stand, a base beam, and a positioning part. The base beam has a positioning side on its outer side. The positioning part includes a reference platform, a positioning structure, and a first drive module. The reference platform is disposed on the positioning side and has a positioning groove. The positioning groove is semi-open and has an opening that communicates with the outside along a reference direction. The positioning groove also has a first sidewall and a second sidewall that intersect each other and are respectively intersecting with the reference direction. A portion of the positioning structure is disposed on the positioning side, and another portion of the structure extends into the base beam. The positioning structure is positioned along the reference direction. The test direction is movable and aligned with the opening; the first drive module is disposed inside the base beam and connected to the positioning structure; the transfer assembly is movably disposed on the base along the first direction, the transfer assembly includes a connecting frame, a load beam and a fixture, the load beam is arranged side by side with the base beam along the first direction, the load beam has a pick-up side, the fixture is disposed on the pick-up side and used to pick up the workpiece, the load beam is rotatably disposed on the connecting frame, and during the rotation of the load beam, the load beam has an attitude in which the pick-up side faces the base beam, and an attitude in which the pick-up side faces the detection device; wherein, the base beam is rotatably disposed on the stand and can be rotated to the attitude in which the positioning side faces the load beam.

[0006] In the aforementioned detection device, the reference platform of the positioning component has a semi-open positioning groove. The positioning component is aligned with the opening of the positioning groove. Therefore, when the positioning component moves towards the reference platform along the reference direction, it can cooperate with the first and second sidewalls of the positioning groove to clamp the workpiece, thereby positioning the workpiece. Furthermore, since the first and second sidewalls intersect each other and with the reference direction respectively, when the positioning component pushes the workpiece along the reference direction until it simultaneously contacts the first and second sidewalls, the workpiece can be completely positioned within the corresponding surfaces. The positioning component can complete workpiece positioning through the reference platform and the positioning component, eliminating the need for movable components in both directions, thus simplifying the structure. Furthermore, the first drive module is located within the base beam and connected to the positioning component to drive the positioning component to move along the first direction. Since the first drive module is located within the base beam, the installation space on the base beam can be fully utilized, reducing the overall structural size of the positioning component. In other words, by arranging the first drive module within the base beam, the number of components on the positioning side can be relatively reduced, eliminating the need for the positioning side to be configured with a larger structural size to support a greater number of components.

[0007] Furthermore, the carrier beam and the base beam can be rotated to a position where the positioning side and the pickup side face each other, so that the workpiece positioned on the positioning side can be transferred to the fixture on the pickup side, realizing the loading of the positioned workpiece to the transfer assembly. The transfer assembly can move along the first direction, and the carrier beam can also rotate to face the detection module. Thus, under the transport of the transfer assembly, the workpiece can be easily moved to the detection range of the detection module for detection. Attached Figure Description

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Please see Figures 1 to 4 This application provides an embodiment of a detection device 10, which is used for defect detection and dimensional measurement of workpieces. The detection device 10 includes a base 100, a detection module 200, a positioning component 300, and a transfer component 400. Each of the detection module 200, positioning component 300, and transfer component 400 is provided with a base 100. The transfer component 400 is used to transport the workpiece to various workstations. For example, the transfer component 400 can transport the workpiece to the detection range of the detection module 200 for inspection. The positioning component 300 can position the workpiece, improving its positional accuracy and providing a basis for high-precision detection. The positioning component 300 can transfer workpieces with the transfer component 400; that is, the transfer component 400 receives the positioned workpiece and transports it to the detection range of the detection module 200.

[0032] like Figure 3 and Figure 4 The positioning assembly 300 includes a frame 310, a base beam 320, and a positioning component 330. The positioning component 330 is disposed on the base beam 320, and the base beam 320 is disposed on the frame 310. The positioning component 330 includes a reference platform 3310, a positioning structure 3320, and a first drive module 3330. The first drive module 3330 is disposed within the base beam 320 and connected to the positioning structure 3320 to drive the positioning structure 3320 to move closer to and further away from the reference platform 3310 along a reference direction K, thereby cooperating with the reference platform 3310 to position the workpiece. The outer side of the base beam 320 has a positioning side 321, and the reference platform 3310 is disposed on the positioning side 321. Figure 8 The reference platform 3310 has a positioning groove 3311, which is semi-open with an opening 3312. The opening 3312 connects to the outside along the reference direction K. The positioning groove 3311 also has a first side wall 3313 and a second side wall 3314, which intersect each other and are respectively intersected with the reference direction K. Part of the positioning structure 3320 is located on the positioning side 321, and another part of the structure passes through the base beam 320. The positioning structure 3320 is movable along the reference direction K and aligned with the opening 3312.

[0033] In the aforementioned detection device 10, the reference platform 3310 of the positioning component 300 has a semi-open positioning groove 3311. The positioning component 330 is aligned with the opening 3312 of the positioning groove 3311. Therefore, when the positioning component 330 moves along the reference direction K towards the reference platform 3310, it can cooperate with the first sidewall 3313 and the second sidewall 3314 of the positioning groove 3311 to clamp the workpiece, thereby positioning the workpiece. Furthermore, since the first sidewall 3313 and the second sidewall 3314 intersect each other and respectively intersect with the reference direction K, when the positioning component 330 pushes the workpiece along the reference direction K until it simultaneously contacts the first sidewall 3313 and the second sidewall 3314, the workpiece can be completely positioned within the corresponding surface. The positioning component 300 can complete the workpiece positioning through the reference platform 3310 and the positioning component 330, eliminating the need for movable components in two directions, thus simplifying the structure. Furthermore, the first drive module 3330 is disposed within the base beam 320 and connected to the positioning component 330 to drive the positioning component 330 to move along the first direction S1. Since the first drive module 3330 is disposed within the base beam 320, the installation space on the base beam 320 can be fully utilized, reducing the overall structural size of the positioning assembly 300. In other words, by configuring the first drive module 3330 within the base beam 320, the number of components in the positioning side 321 can be relatively reduced, so that the positioning side 321 does not need to be configured with a larger structural size to support a larger number of components.

[0034] Please refer to it again. Figures 2 to 4The transfer assembly 400 is movably mounted on the base 100 along a first direction S1. The transfer assembly 400 includes a connecting frame 401, a carrying beam 402, and a fixture 403. The carrying beam 402 is rotatably mounted on the connecting frame 401, and the fixture 403 is located on the pickup side 402a and used to pick up workpieces. The carrying beam 402 is arranged side-by-side with the base beam 320 along the first direction S1, and the carrying beam 402 has a pickup side 402a. During rotation, the carrying beam 402 has an orientation where the pickup side 402a faces the base beam 320, and an orientation where the pickup side 402a faces the detection device 10. The base beam 320 is rotatably mounted on the stand 310, and the base beam 320 can rotate to an orientation where its positioning side 321 faces the carrying beam 402. The carrier beam 402 and the base beam 320 can be rotated to face each other on the positioning side 321 and the pickup side 402a, respectively. This allows the workpiece positioned on the positioning side 321 to be transferred to the fixture 403 on the pickup side 402a, thus loading the positioned workpiece onto the transfer assembly 400. The transfer assembly 400 can move along the first direction S1, and the carrier beam 402 can also rotate to face the detection module 200. Therefore, under the transport of the transfer assembly 400, the workpiece can be easily moved to the detection range of the detection module 200 for inspection. Furthermore, when the transfer assembly 400 is within the detection range of the detection module 200, the carrier beam 402 can be rotated relative to the connecting frame 401 to adjust the orientation of the pickup side 402a, allowing the workpiece picked up on the pickup side 402a to have different orientations relative to the detection device 10, improving the comprehensiveness of the inspection.

[0035] Please see Figure 1 and Figure 2 In one embodiment, at least two transfer components 400 are arranged side-by-side along a first direction S1, and the load beams 402 of adjacent transfer components 400 can be rotated to a position where their respective pick-up sides 402a face each other along the first direction S1. That is, during the rotation of the load beams 402 of each transfer component 400, the load beams 402 also have a position where their pick-up sides 402a face the load beams 402 of the adjacent transfer component 400. In other words, the pick-up sides 402a of the two transfer components 400 can be rotated to a facing position to transfer workpieces to each other. It can be understood that since the transfer components 400 are arranged side-by-side along the first direction S1, and each transfer component 400 can also move independently along the first direction S1, adjacent transfer components 400 can move along the first direction S1 to a position where their respective pick-up sides 402a are sufficiently close to each other to transfer workpieces to each other. It should be noted that when the pick-up sides 402a of the two transfer components 400 are close enough to each other, their respective jigs 403 can pick up the workpiece together. After the jig 403 of one transfer component 400 removes the force of picking up the workpiece, it can transfer the workpiece to the other transfer component 400.

[0036] As one example, fixture 403 can pick up the workpiece by means of vacuum adsorption or clamping.

[0037] Please see Figure 6 Taking two transfer components 400 as an example, the two transfer components 400 are the first transfer component 410 and the second transfer component 420. The connecting frame 401 of the first transfer component 410 is the first connecting frame 411, the pickup side 402a of the first transfer component 410 is the first pickup side 412a, the load beam 402 of the first transfer component 410 is the first load beam 412, and the fixture 403 of the first transfer component 410 is the first fixture 413. The first load beam 412 is rotatably connected to the first connecting frame 411 about the first axis O1, and the first fixture 413 is rotatably connected to the first load beam 412 about the second axis O2. Furthermore, the first axes O1 of the multiple first fixtures 413 are arranged in parallel.

[0038] The connecting frame 401 of the second transfer assembly 420 is the second connecting frame 421, the pickup side 402a of the second transfer assembly 420 is the second pickup side 422a, the carrying beam 402 of the second transfer assembly 420 is the second carrying beam 422, and the fixture 403 of the second transfer assembly 420 is the second fixture 423. The second carrying beam 422 is rotatably connected to the second connecting frame 421 about the first axis O1, and the second fixture 423 is rotatably connected to the second carrying beam 422 about the second axis O2. Further, the first axes O1 of the multiple second fixtures 423 are arranged in parallel. The distance between adjacent first fixtures 413 corresponds to the distance between adjacent second fixtures 423, so that when the first pickup side 412a and the second pickup side 422a are arranged facing each other, the multiple first fixtures 413 and the multiple second fixtures 423 can correspond one-to-one to transfer workpieces to each other.

[0039] Since both the first transfer component 410 and the second transfer component 420 are transfer components 400, all the features of the transfer component 400 described in each embodiment are also present in the first transfer component 410 and the second transfer component 420, unless there is any contradiction.

[0040] It should be noted that the first transfer assembly 410 and the second transfer assembly 420 transfer workpieces to each other with their pick-up sides 402a facing each other. Therefore, the workpieces picked up by the first transfer assembly 410 and the workpieces picked up by the second transfer assembly 420 are in different orientations. With this arrangement, when different transfer assemblies 400 carry workpieces to the detection range of the detection module 200, the areas of the workpieces being detected are different, thus improving the comprehensiveness of the detection.

[0041] Please see Figure 6In one embodiment, the detection device 10 further includes a transport module 800, which is connected to the transfer assembly 400 to drive the transfer assembly 400 to move along a first direction S1. As one example, multiple transfer assemblies 400 may all be driven by the transport module 800 to move along the first direction S1. For example, the transport module 800 may be configured as a multi-motor linear motor module to drive each transfer assembly 400 to move independently along the first direction S1. Of course, in other embodiments, multiple transport modules 800 may be configured, each connected to a transfer assembly 400 in a one-to-one correspondence to drive each transfer assembly 400 to move along the first direction S1.

[0042] Furthermore, the transport module 800 can be connected to the connecting frame 401 to drive the transfer assembly 400 as a whole to move along the first direction S1.

[0043] Please see Figure 4 In one embodiment, the positioning structure 3320 has multiple positioning groups 301. Multiple reference platforms 3310 are spaced apart on the base beam 320 along its extension direction. The positioning structure 3320 includes a carrier plate 3324, on which the multiple positioning groups 301 are disposed. The carrier plate 3324 is connected to a first drive module 3330. That is, the first drive module 3330 drives the carrier plate 3324 to move along a reference direction K, thereby causing the multiple positioning groups 301 to move synchronously along the reference direction K. Further, the multiple positioning groups 301 are spaced apart on the carrier plate 3324 along the extension direction of the base beam 320, and correspond one-to-one with the openings 3312 of the multiple reference platforms 3310 along the reference direction K. Thus, driven by the carrier plate 3324, the multiple positioning groups 301 can cooperate one-to-one with the multiple reference platforms 3310 to jointly position the workpiece, thereby achieving synchronous positioning of multiple workpieces. In this embodiment, the configuration eliminates the need for multiple first drive modules 3330 to drive each positioning group 301 to move, thus reducing the number of components included in the positioning component 300, simplifying its structure and reducing space occupation.

[0044] It should be understood that the positioning assembly 301 can be inserted through the opening 3312 to engage with the wall of the positioning groove 3311 to position the workpiece. For example, as will be mentioned below, the positioning assembly 301 may also include a pusher 3322, which can be inserted through the opening 3312 to engage with the wall of the positioning groove 3311 to position the workpiece. Alternatively, the positioning assembly 301 may be located entirely outside the positioning groove 3311, engaging with the wall of the positioning groove 3311 to position the workpiece by abutting the portion of the workpiece exposed outside the opening 3312.

[0045] Please see Figure 7 Combined Figure 3In one embodiment, the base beam 320 includes a support plate 322 and a cover 323. The cover 323 is connected to the support plate 322 and encloses it to form a receiving cavity 320a. The first drive module 3330 is disposed within the receiving cavity 320a. The support plate 322 has the aforementioned positioning side 321, which is arranged on the side of the support plate 322 opposite to the cover 323. The support plate 322 has a through hole 322a that connects to the receiving cavity 320a. The positioning structure 3320 also includes a connecting plate 3325, which passes through the through hole 322a and connects the carrier plate 3324 and the first drive module 3330, so that the drive module drives the carrier plate 3324 to move along the reference direction K.

[0046] In one embodiment, the pallet 322 has a guide rail 322b, which is located on the positioning side 321 and extends along the reference direction K, and the positioning structure 3320 slides with the guide rail 322b.

[0047] Please see Figure 8 Combined Figure 4 In one embodiment, the positioning structure 3320 includes a fixed base 3321, a push block 3322, and an elastic element 3323. The fixed base 3321 is disposed on the carrier plate 3324, and both the push block 3322 and the elastic element 3323 are disposed on the fixed base 3321. The push block 3322 is used to hold the workpiece and is movably disposed on the fixed base 3321 along a reference direction K. The elastic element 3323 extends along the reference direction K and elastically connects the push block 3322 and the fixed base 3321. Thus, under the elastic support of the elastic element 3323, the push block 3322 can elastically float relative to the fixed base 3321, reducing the risk of the push block 3322 damaging the workpiece by clamping it against the wall of the positioning groove 3311.

[0048] Furthermore, the fixed base 3321 has a slide rail 3321b, which extends along the reference direction K, and the push block 3322 slides in conjunction with the slide rail 3321b. Thus, the slide rail 3321b can provide guidance and limit for the movement of the push block 3322 along the reference direction K, thereby improving the stability of the movement of the push block 3322.

[0049] Please see Figure 4 In one embodiment, the positioning group 301 includes a fixed base 3321 and a push block 3322 and an elastic member 3323 correspondingly disposed on the fixed base 3321, that is, the fixed base 3321 and the push block 3322 and the elastic member 3323 disposed on the fixed base 3321 constitute the positioning group 301.

[0050] In one embodiment, the elastic element 3323 can be configured as a compression spring. Of course, the elastic element 3323 can also be configured as other elements with elastic support function.

[0051] Please continue reading. Figure 8 Combined Figure 4 In one embodiment, the fixed base 3321 has a limiting groove 3321a that extends along a reference direction K. The push block 3322 has a limiting portion 3322a that passes through the limiting groove 3321a and is movable along the reference direction K to positions that abut against the groove wall of the limiting groove 3321a. Thus, the elastic floating stroke of the push block 3322 can be limited by the groove wall of the limiting groove 3321a, balancing the positional stability and elastic floating capability of the push block 3322.

[0052] Please refer to it again. Figure 7 In one embodiment, the positioning component 330 further includes a buffer 340 disposed on the base beam 320. The buffer 340 abuts against the connecting plate 3325 to buffer the reciprocating motion of the connecting plate 3325. At least two buffers 340 are arranged at intervals along the reference direction K and are located on opposite sides of the connecting plate 3325, respectively. Thus, the reciprocating stroke of the positioning structure 3320 can be limited by the two buffers 340, and the stroke of the positioning structure 3320 can have a certain floating space.

[0053] Please see Figure 2 and Figure 3 In one embodiment, the base beam 320 extends along the second direction S2, a plurality of reference platforms 3310 are spaced apart along the second direction S2 on the positioning side 321, and a plurality of positioning groups 301 are spaced apart along the second direction S2 on the carrier plate 3324.

[0054] Furthermore, the second direction S2 is perpendicular to the first direction S1.

[0055] Please refer to it again. Figure 3 In one embodiment, the base beam 320 is rotatably connected to the support frame 310 about a reference axis O. The reference axis O is parallel to the second direction S2. Further, the positioning assembly 300 includes a rotary actuator 350, which is disposed on one of the support frame 310 and the base beam 320 and connected to the other to drive the base beam 320 to rotate about the reference axis O.

[0056] Please refer to 7. In one embodiment, the first sidewall 3313 may extend along the first direction S1, and the second sidewall 3314 may extend along the second direction S2. The reference direction K is at the same angle as the first direction S1 and the second direction S2. Of course, in other embodiments, the shape and extension direction of the first sidewall 3313 and the second sidewall 3314, as well as the relationship between the reference direction K and the first direction S1 and the second direction S2, can be configured according to the shape of the workpiece.

[0057] In one embodiment, the pusher block 3322 may also be configured to have an adapter groove (not shown in the figure, the same below), the groove wall of the adapter groove is used to contact the workpiece, and the shape of the adapter groove can match the shape of the workpiece.

[0058] Please see Figure 5 and Figure 6 Combined Figure 6 In one embodiment, the support beam 402 is rotatably connected to the connecting frame 401 about a first axis O1, and the fixture 403 is rotatably connected to the support beam 402 about a second axis O2. The first axis O1 and the second axis O2 are not parallel, that is, the first axis O1 and the second axis O2 are coplanar and intersecting straight lines or skew straight lines. In short, the workpiece picked up by the fixture 403 can rotate with the fixture 403 about the second axis O2, and the workpiece can revolve with the fixture 403 and the support beam 402 about the first axis O1, so that all areas of the workpiece can be fully exposed within the detection range of the detection device 10, improving the comprehensiveness of the detection.

[0059] Furthermore, there are multiple fixtures 403, which are arranged at intervals along the extension direction of the load beam 402.

[0060] In one embodiment, the load beam 402 extends along the second direction S2. The first axis O1 is parallel to the second direction S2.

[0061] Please see Figure 9 In one embodiment, the transfer assembly 400 further includes a driving component disposed on the carrier beam 402 and connected to multiple fixtures 403. The driving component drives the multiple fixtures 403 to rotate synchronously relative to the carrier beam 402. The synchronous rotation of the multiple fixtures 403 allows them to switch postures, facilitating unified detection by the detection device 10. Furthermore, the driving component is disposed within the carrier beam 402, with one end of each fixture 403 passing through the carrier beam 402 and connected to the driving component, and the other end extending outward from the carrier beam 402 for picking up workpieces.

[0062] like Figure 9As one example, the driving component includes multiple driving modules, each including a rotation driver (not shown in the figure, the same below) and a rotation motor 404, with the rotation driver connected to the rotation motor 404. The rotation motors 404 of the multiple driving modules are connected one-to-one with multiple fixtures 403, and each driving module independently drives each fixture 403 to rotate synchronously. Because each driving module independently drives the rotation of each fixture 403, when one or more fixtures 403 have different postures from other fixtures 403, the posture of the one or more fixtures 403 can be independently adjusted by the driving modules to move them to the same posture as the other fixtures 403. In other words, in this embodiment, by independently driving the rotation of each fixture 403 by each driving module, the posture consistency of each fixture 403 during movement can be ensured, improving the posture consistency of the workpiece picked up by the fixture 403 and facilitating inspection and processing.

[0063] As another example, the driving component includes a driving module (not shown, the same below) and a transmission module (not shown, the same below). The transmission module is connected to each fixture 403, and the driving module is connected to the transmission module to drive each fixture 403 to rotate synchronously. The transmission module is configured as one of the following: rack and pinion drive, belt drive, chain drive, and worm gear drive. For example, the transmission module includes a first transmission member and a second transmission member, taking belt drive as an example. In this case, the first transmission member can be configured as a synchronous belt, and the second transmission member can be configured as a synchronous pulley. There are multiple second transmission members, and each of the multiple second transmission members is connected to a multiple fixture 403 in a one-to-one correspondence. The driving module is connected to one of the second transmission members, and the first transmission member is wrapped around the outside of each second transmission member so that when one of the second transmission members is driven to rotate, it drives the other second transmission members to rotate together, so that each fixture 403 rotates synchronously.

[0064] Please refer to it again. Figure 1 and Figure 2 In one embodiment, the base 100 further includes a gantry 500, which is mounted on the base 100. The detection module 200 is mounted on the gantry 500 to have a higher position relative to the transfer assembly 400, thus providing a better shooting angle. Further, the gantry 500 can be mounted on the base 100 along a third direction S3, such that the detection module 200 is positioned above the transfer assembly 400 in the third direction S3. The third direction S3 intersects with both the first direction S1 and the second direction S2, meaning that the first direction S1, the second direction S2, and the third direction S3 intersect each other pairwise. Even further, the first direction S1, the second direction S2, and the third direction S3 are perpendicular to each other pairwise.

[0065] Please see Figure 10a and Figure 10bDuring inspection, the inspection module 200 needs to be sufficiently close to the workpiece 20 picked up by the fixture 403 to ensure the accuracy of the processing. Figure 10a As shown, due to the physical structure of the support beam 402, there is a possibility of obstruction and interference between the support beam 402 and the detection module 200, preventing the detection module 200 from getting sufficiently close to the workpiece 20 picked up by the fixture 403. (See reference...) Figure 10b Combined Figure 5 One solution in traditional technology is to increase the axial length of the fixture 403 on the second axis O2, so that the workpiece 20 picked up by the fixture 403 can be sufficiently far away from the carrier beam 402, thereby preventing interference between the carrier beam 402 and the detection module 200. However, the traditional solution also has the problem of the workpiece 20 being too far from the first axis O1, resulting in an excessively large rotation radius when the workpiece 20 rotates with the carrier beam 402. The rotation radius of the workpiece 20 in the traditional technology is as follows: Figure 10b As indicated by the Chinese standard number L1.

[0066] To reduce the rotation radius of workpiece 20 when it rotates with the load beam 402, please refer to [link / reference needed]. Figure 5 and Figure 11 Combined Figure 10c In one embodiment, the support beam 402 further includes a first side portion 402b and a second side portion 402c, which are arranged sequentially in a circumferential direction around the extension axis of the support beam 402 (i.e., the first axis O1). The fixture 403 is positioned closer to the side where the first side portion 402b or the second side portion 402c is located on the pick-up side portion 402a, i.e., the fixture 403 is offset. Therefore, the fixture 403 is positioned closer to the edge region of the support beam 402, allowing the detection module 200 to easily approach the workpiece 20 picked up by the fixture 403 without interfering with the support beam 402. This embodiment is configured in such a way that interference and collision between the detection module 200 and the support beam 402 are avoided while reducing the rotation radius of the workpiece 20. In this embodiment, the rotation radius of the workpiece 20 is as follows: Figure 10c As indicated by reference numeral L2, L1 > L2. It is important to emphasize that when the radius of rotation of workpiece 20 around the load beam 402 is too large, workpiece 20 is prone to vibration and swaying, resulting in positional instability. This embodiment is designed to reduce the radius of rotation of workpiece 20 around the first axis O1, thereby improving the positional stability of workpiece 20.

[0067] Furthermore, the offset orientation of the first fixture 413 on the first carrier beam 412 can be opposite to the offset orientation of the second fixture 423 on the second carrier beam 422, so that when the pick-up sides 402a of the two transfer components 400 face each other, the positions of each fixture 403 correspond and the workpiece 20 is transferred to each other.

[0068] Please see Figure 11 In one embodiment, the transfer assembly 400 further includes a pitch actuator 405, which is connected to the connecting frame 401 and the carrier beam 402 to drive the carrier beam 402 to rotate about a first axis O1. The pitch actuator 405 is disposed on the carrier beam 402 and located to the side in the direction of the second axis O2. Since the pitch actuator 405 is used to drive the carrier beam 402 to rotate about the first axis O1, there is usually a certain positional relationship between the pitch actuator 405 and the first axis O1. In the conventional art, based on various considerations, the pitch actuator 405 is usually arranged inside the carrier beam 402, so that the pitch actuator 405 is located at the bottom of the fixture 403. As a result, the fixture 403 and the self-rotating motor 404 have to be installed on the second axis O2 at a position away from the pitch actuator 405 to avoid interference, which also results in the fixture 403 being relatively far away from the first axis O1 and having a larger rotation radius. In this application, the pitch actuator 405 is located beside the second axis O2. The pitch actuator 405 will not occupy the space of the load beam 402 on the second axis O2, so that the distribution position of the fixture 403 on the second axis O2 is not limited by the position of the pitch actuator 405. Therefore, the fixture 403 can be configured to be closer to the first axis O1 to reduce the rotation radius of the workpiece 20.

[0069] Please see Figure 11 Combined Figure 6 In one embodiment, the pitch actuator 405 may be located outside the load beam 402. Further, the pitch actuator 405 may be located on the side of the first side 402b and the second side 402c that is relatively far from the fixture 403. For example, if the fixture 403 is located closer to the side of the first side 402b on the pickup side 402a, then the pitch actuator 405 is located on the second side 402c. Alternatively, if the fixture 403 is located closer to the side of the second side 402c on the pickup side 402a, then the pitch actuator 405 is located on the first side 402b. This reduces the risk of the pitch actuator 405 interfering with the detection module 200 and also balances the weight distribution of the components carried by the load beam 402.

[0070] Please see Figure 2In one embodiment, multiple transfer components 400 can share the same detection module 200 to reduce the idle time of the detection module 200 and improve efficiency. This arrangement also simplifies the structure and reduces costs. As one example, while the first transfer component 410 is transporting a workpiece to the detection range of the detection module 200 for detection, the second transfer component 420 can exchange workpieces with an external material handling device. While the second transfer component 420 is transporting a workpiece to the detection range of the detection module 200 for detection, the first transfer component 410 can exchange workpieces with another external material handling device.

[0071] Please see Figure 12 Combined Figure 1 and Figure 2 In one embodiment, the detection module 200 is disposed on one side of the gantry 500 in the first direction S1. The detection module 200 includes a second drive module 210, a third drive module 220, a first mounting plate 230, a second mounting plate 240, and a detection module 250, with at least one detection module 250 disposed on the second mounting plate 240. The third drive module 220 is connected to the second mounting plate 240 to drive the second mounting plate 240 towards and away from the base 100 in the third direction S3. Thus, the second mounting plate 240 can drive at least one detection module 250 towards and away from the base 100 in the third direction S3. The third drive module 220 is disposed on the first mounting plate 230, and the second drive module 210 is disposed on the gantry 500 and connected to the first mounting plate 230 to drive the first mounting plate 230 to move in the second direction S2, causing the second mounting plate 240 and the detection module 250 to move accordingly in the second direction S2.

[0072] Furthermore, the number of detection modules 250 can be the same as the number of fixtures 403 in the transfer assembly 400. Multiple detection modules 250 are arranged at intervals along the second direction S2, and the distance between adjacent detection modules 250 corresponds to the distance between adjacent fixtures 403. Thus, multiple detection modules 250 can perform one-to-one detection on the workpieces picked up by the multiple fixtures 403.

[0073] Please see Figure 12 In one embodiment, the detection module 250 includes components such as a camera 251, a lens 252, and a light source 253.

[0074] Please see Figure 13 and Figure 14In one embodiment, the detection device 10 further includes a conveying assembly 600, which is disposed on opposite sides of the gantry 500 along the first direction S1, along with the detection module 200. The conveying assembly 600 is used to pick up and transfer the workpieces carried by the transfer assembly 400. For example, the detection device 10 can use the conveying assembly 600 to transfer the inspected workpieces carried by the transfer assembly 400 to a material handling device, and then the material handling device can transfer them to other workstations.

[0075] Please see Figure 13 and Figure 14 In one embodiment, the handling assembly 600 includes a fourth drive module 610, a fifth drive module 620, an extension frame 630, a third mounting plate 640, a fourth mounting plate 650, and a pickup component 660. The extension frame 630 is disposed on the gantry 500, and the pickup component 660 is used to pick up workpieces. At least one pickup component 660 is disposed on the fourth mounting plate 650. The fifth drive module 620 drives the fourth mounting plate 650 to move along a third direction S3 to approach and move away from the base 100. The fifth drive module 620 is disposed on the third mounting plate 640, and the fourth drive module 610 is disposed on the extension frame 630 and connected to the third mounting plate 640 to drive the third mounting plate 640, the fifth drive module 620 disposed on the third mounting plate 640, and the pickup component 660 to move along a first direction S1.

[0076] Furthermore, the cantilever frame 630 has a track 631, and the fourth mounting plate 650 slides in conjunction with the track 631.

[0077] In one embodiment, the number of pick-up pieces 660 can be matched with the number of fixtures 403, and multiple pick-up pieces 660 are arranged at intervals along the second direction S2 to pick up the workpieces at each fixture 403 in a one-to-one correspondence.

[0078] Furthermore, the pickup 660 can be configured to pick up workpieces in a manner such as clamping pickup and vacuum adsorption pickup.

[0079] In one embodiment, the first drive module 3330, the second drive module 210, the third drive module 220, the fourth drive module 610, and the fifth drive module 620 can be configured as linear motor modules or other modules with linear drive functions (e.g., cylinders, hydraulic cylinders, etc.). Alternatively, the first drive module 3330, the second drive module 210, the third drive module 220, the fourth drive module 610, and the fifth drive module 620 can be configured to include a driver and a transmission mechanism, with the transmission mechanism connecting the driver and a corresponding component, and the driver driving the corresponding component to move through the transmission mechanism. As one example, the fifth drive module 620 includes a pickup driver and a transmission component, with the transmission component drivingly connecting the pickup driver and the fourth mounting plate 650. The transmission component can be configured as any one of rack and pinion drive, belt drive, chain drive, and worm gear drive.

[0080] Please see Figure 1 and Figure 2 In one embodiment, the detection device 10 further includes a dust removal component 700, which is disposed on the base 100 and used to remove dust from the workpiece, thereby improving the accuracy of the detection. The dust removal component 700 is located along the first direction S1 on the side of the positioning component 300 near the transfer component 400, leaving space on the other side to facilitate the interaction between the positioning component 300 and the material conveying device for workpiece transfer. As one example, the dust removal component 700 can achieve dust removal by airflow blowing. In this case, the dust removal component 700 has an air outlet (not shown in the figure, the same below) facing the positioning component 300. It is understood that the positioning component 300 is typically configured to position the workpiece before detection; therefore, configuring the air outlet to face the positioning component 300 allows for dust removal during positioning, improving the accuracy of the detection.

[0081] 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.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
