[0038] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0040] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" of the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" of the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0041] It is to be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used herein for purposes of explanation only and are not intended to be limiting.

[0042] It is to be further noted that the embodiments of the present application will focus on the conveying of workpieces to illustrate how the detection apparatus can achieve higher versatility. Therefore, as shown in FIG. 1, in order to facilitate the understanding of the conveying of workpieces, in the embodiments, the side of the workpiece conveying path relatively close to the feeding side is referred to as the upstream (e.g., the side indicated by SY in FIG. 1), and the side of the workpiece conveying path relatively close to the discharging side is referred to as the downstream (e.g., the side indicated by XY in FIG. 1).

[0043] Referring to FIGS. 1 and 2, the detection apparatus 10 provided by an embodiment of the present application comprises a feeding machine 11, detection machines 12, and a discharging machine 13 arranged in sequence, and at least two detection machines 12 are independently arranged between the feeding machine 11 and the discharging machine 13.

[0044] Referring to FIG. 3, the detection apparatus 10 further comprises a transfer component 100 and a transfer component 220, the transfer component 100 is arranged between the feeding machine 11 and the detection machines 12 for conveying workpieces, and the transfer component 220 is arranged between the detection machines 12 and the discharging machine 13 for conveying workpieces. Any detection machine 12 comprises a transfer component 210, and the transfer components 210 of adjacent detection machines 12 can convey workpieces to each other. Meanwhile, the transfer component 210 can also receive workpieces conveyed by the transfer component 100, and the transfer component 210 is also used for conveying workpieces to the transfer component 220.

[0045] The detection equipment 10 has at least two detection machines 12 independently arranged between the feeding machine 11 and the discharging machine 13, and each detection machine 12 comprises a transfer component 210 capable of transferring the workpiece to the adjacent detection machine 12. Therefore, the increase or decrease of the detection machines 12 between the detection machines 12 does not affect the overall conveying of the detection equipment 10, and the expansibility of the detection equipment 10 is improved. In addition, the transfer component 210 can also receive the workpiece transferred by the transfer component 100 and transfer the workpiece to the transfer component 220, so that each detection machine 12 arranged between the feeding machine 11 and the discharging machine 13 can receive the workpiece from the feeding machine 11 and transfer the workpiece to the discharging machine 13. Therefore, each detection machine 12 can be added between the feeding machine 11 and the discharging machine 13 as an independent expansion module to expand the detection station, or be freely removed. In this way, the detection machines 12 can be added or removed according to different detection requirements, and it is not necessary to design a detection line for each different product, and the expansibility and versatility of the detection equipment 10 are improved.

[0046] As shown in FIG. 2, in one embodiment, the feeding machine 11 comprises a feeding table 11a, the detection machine 12 comprises a detection table 300, and the discharging machine 13 comprises a discharging table 13a. The transfer component 100 can be arranged on one of the feeding table 11a and the detection table 300 at the most upstream, or the transfer component 100 can be arranged on both of them. Similarly, the transfer component 220 can be arranged on one of the detection table 300 at the most downstream and the discharging table 13a, or the transfer component 220 can be arranged on both of them. The following embodiments are described by taking that the transfer component 100 and the transfer component 220 are arranged on the detection table 300 for the convenience of description, and the same is true for other cases, and thus will not be described again.

[0047] In one embodiment, the detection machine 12 is detachably connected with at least one of the feeding machine 11, the discharging machine 13 and the other detection machine 12 arranged adjacent thereto. In other words, the detection machines 12 are detachably connected with each other, the detection machine 12 is detachably connected with the feeding machine 11, and the detection machine 12 is detachably connected with the discharging machine 13. In this way, the flexibility of expansion of each component module included in the detection equipment 10 is improved.

[0048] Further, the detection apparatus 10 further comprises a connecting structure (not shown in the figure, the same below) which is detachably connected between adjacent detection machines 12. For example, the connecting structure comprises a connecting piece (not shown in the figure, the same below) and two threaded locking pieces (not shown in the figure, the same below), and the two ends of the connecting piece are detachably connected with two adjacent detection machines 12 through the two threaded locking pieces. Similarly, the detection machine 12 and the feeding machine 11, and the detection machine 12 and the discharging machine 13 can also be detachably connected by using the connecting structure. Of course, the detachable connection mode can also be set to other forms according to requirements, such as buckle connection, pin plug-in fixed, etc., which will not be described one by one here.

[0049] In one embodiment, as shown in FIG. 2, the feeding machine 11 can comprise a feeding carrying structure 600 for transferring the workpiece to the transfer component 100. The discharging machine 13 can comprise a discharging carrying structure 700 for receiving the workpiece transferred by the detection machine 12.

[0050] Further, the transfer component 100 can be used to position the picked workpiece to improve the position accuracy of the workpiece fed by the feeding machine 11, so as to facilitate the detection effect. Similarly, the transfer component 220 can be used to position the picked workpiece to improve the position accuracy of the workpiece, so as to facilitate the discharging filling.

[0051] Further, the number of detection machines 12 between the feeding machine 11 and the discharging machine 13 can be 2, 3, 4 or 5, etc., which can be set according to actual requirements, which is not limited here. Moreover, the detection mode of the detection machine 12 is not limited in the embodiments of the present application, as shown in FIG. 3, for example, the detection machine 12 can comprise a visual detection module to perform visual detection on the workpiece. At the same time, each detection machine 12 can adopt the same detection mode, or at least one detection machine 12 has a detection mode different from that of the other detection machines 12, which can be set according to requirements in actual application, which will not be described here.

[0052] Please refer to FIGS. 3-5, in one embodiment, the transfer component 100 comprises a first rack 110 and a first body 120, and the first body 120 is rotatably arranged on the first rack 110. The first body 120 can position the workpiece on a bearing side 121 of the first body 120, and the first body 120 can adjust the orientation of the bearing side 121 when rotating, so as to receive the workpiece transferred by the feeding machine 11 and transfer the workpiece to the transfer component 210. As shown in FIG. 4, it is easy to understand that the transfer component 100 is arranged between the feeding machine 11 and the detection machine 12, so that the feeding machine 11 and the detection machine 12 are located at relatively upstream and relatively downstream respectively for the transfer component 100. Therefore, the first body 120 is arranged to drive the workpiece to rotate to the upstream and the downstream, so as to transfer the workpiece transferred by the feeding machine 11 to the detection machine 12.

[0053] Further, as shown in FIG. 4, the first body 120 can rotate relative to the first frame 110 about the first axis O1.

[0054] In one embodiment, the carrying side 121 is provided with a limiting structure (not shown in the drawings), which can limit the workpiece when the feeding machine 11 places the workpiece on the carrying side 121, so that the workpiece can rotate with the first body 120.

[0055] Please refer to FIG. 5 and FIG. 6, in one embodiment, the first body 120 includes a carrying body 122, a first pushing piece 123 and a second pushing piece 124. The carrying body 122 is rotationally connected with the first frame 110, and the carrying side 121 is arranged on the carrying body 122. The carrying side 121 is provided with a positioning block 125. The first pushing piece 123 and the second pushing piece 124 are movably arranged on the carrying body 122, and move towards and away from the positioning block 125 in different directions to jointly clamp the workpiece. By pushing the workpiece from different directions by the first pushing piece 123 and the second pushing piece 124, on the one hand, the workpiece can be pushed to the desired position, i.e. positioned. On the other hand, the first pushing piece 123 and the second pushing piece 124 can also jointly clamp the workpiece to limit the workpiece, so that the workpiece can rotate with the first body 120.

[0056] It should be noted that the first pushing piece 123 and the second pushing piece 124 can be used as part of the limiting structure to limit and fix the workpiece. Alternatively, in other embodiments, the first pushing piece 123 and the second pushing piece 124 are only used for positioning the workpiece, and the transmission component 100 can also be provided with a picking structure (not shown in the drawings), which can stably limit and fix the workpiece on the carrying side 121 of the first body 120. The picking structure can be, for example, vacuum suction picking, electromagnetic suction picking, etc.

[0057] It should be further noted that the transmission component 100 can be provided with a plurality of drivers connected with the first pushing piece 123 and the second pushing piece 124 respectively to drive the first pushing piece 123 and the second pushing piece 124 to move respectively. Alternatively, the first pushing piece 123 and the second pushing piece 124 can be connected through a linkage structure (not shown in the drawings), so that driving one of the first pushing piece 123 and the second pushing piece 124 by the driver can drive the other one to move synchronously through linkage.

[0058] Referring to FIG. 3, in an embodiment, the detection machine 12 further comprises a plurality of detection modules 400, which are arranged on the detection table 300. Referring to FIG. 4 and FIG. 7, the detection machine 12 can comprise a plurality of transfer components 210, which are movably arranged on the detection table 300 to carry the workpiece to the detection range of the detection module 400. The transfer component 210 is used to pick up the workpiece transferred by the transfer component 100, and the transfer component 210 is also used to transfer the workpiece to the transfer component 210 of another detection machine 12 or the unloader 13.

[0059] Referring to FIG. 4 and FIG. 7, in an embodiment, the detection table 300 is provided with a transfer platform 310, and the plurality of transfer components 210 are connected with the transfer platform 310, and the transfer platform 310 can drive each transfer component 210 to move respectively.

[0060] It can be understood that when the workpiece transfer requirement and the detection requirement are met, the detection machine 12 can also be arranged to comprise only one transfer component 210.

[0061] Further, the transfer component 210 can comprise a second machine frame 211 and a second machine body 212, and the second machine body 212 is rotationally connected with the second machine frame 211. The second machine body 212 is provided with a transfer side 212a, and the second machine body 212 can position the workpiece on the transfer side 212a, and the second machine body 212 can adjust the angle of the transfer side 212a towards the detection module 400 when the second machine body 212 rotates relative to the second machine frame 211. That is, the second machine body 212 can adjust the angle of the workpiece towards the detection module 400 when the second machine body 212 rotates relative to the second machine frame 211, so as to facilitate the full detection of the workpiece. The second machine body 212 comprises a transfer body 212b and a plurality of pickup jigs 212c arranged on the transfer body 212b, and the plurality of pickup jigs 212c are spaced apart and used to fix the workpiece. The transfer side 212a is arranged on the transfer body 212b, and the plurality of pickup jigs 212c are arranged on the transfer side 212a of the transfer body 212b. It can be understood that the second machine body 212 can also make the transfer side 212a face upstream or downstream when the second machine body 212 rotates relative to the second machine frame 211.

[0062] As shown in FIG. 4, further, the second machine body 212 can rotate relative to the second machine frame 211 about a second axis O2 to switch between the direction towards upstream and the direction towards downstream. The pickup jig 212c can rotate relative to the transfer body 212b about a third axis O3. The second axis O2 intersects with the third axis O3. In this way, after the transfer component 210 moves the workpiece to the detection module 400, the second machine body 212 and / or the pickup jig 212c can be driven to rotate, so that the workpiece is in the detection range of the detection module 400 in different angular postures, thereby improving the comprehensiveness of detection.

[0063] In one embodiment, the pick-up tool 212c can pick up the workpiece in a manner corresponding to the type, shape, material, etc. of the workpiece, such as vacuum suction, magnetic attraction, or clamping.

[0064] The second body 212 of the transfer member 210 can rotate relative to the second frame 211 to face upstream or downstream. When the transfer member 210 faces downstream, the transfer member 210 can deliver the workpiece to the unloader 13 or to the delivery member 100 of another inspection machine 12.

[0065] Referring to FIG. 4, in one embodiment, the transfer member 220 includes a support 221 and a pick-up tool 222. The support 221 is arranged on the inspection table 300, and the pick-up tool 222 is movably arranged on the support 221. The pick-up tool 222 moves relative to the support 221 in at least two intersecting directions, and is used to pick up the workpiece carried by the transfer member 210 and transfer it to the unloader 13.

[0066] Further, the support 221 can adopt a gantry structure to support the pick-up tool 222. The support 221 includes longitudinal beams 221a and a cross beam 221b. The two longitudinal beams 221a are arranged on the two sides of the transfer platform 310, and the cross beam 221b is arranged to cross the transfer platform 310 and slide relative to the longitudinal beams 221a. The pick-up tool 222 is arranged on the cross beam 221b and slides relative to the cross beam 221b. In this way, the cross beam 221b slides relative to the longitudinal beams 221a, and the pick-up tool 222 slides relative to the cross beam 221b, so that the position of the pick-up tool 222 can be adjusted to the desired position.

[0067] Regarding the delivery of the workpiece between the delivery member 100 and the transfer member 210, referring to FIGS. 4, 5 and 7, it is easy to understand that the first body 120 and the second body 212 can rotate, and can be rotated to face each other (i.e., the carrying side 121 and the transfer side 212a are distributed in opposite directions). At this time, the delivery member 100 picks up one side of the workpiece, and the transfer member 210 can approach the delivery member 100 and pick up the other side of the workpiece arranged in the opposite direction, so as to realize the delivery of the workpiece.

[0068] It should be noted that the transfer component 100 is not limited to being arranged between the feeding machine 11 and the most upstream detection machine 12. The transfer component 100 can be multiple, and the transfer component 100 is arranged on the upstream side of the detection machine 12 one-to-one corresponding to the detection machine 12. Similarly, the transfer component 220 is not limited to being arranged between the most downstream detection machine 12 and the unloading machine 13. The transfer component 220 can be multiple, and the transfer component 220 is arranged on the downstream side of the detection machine 12 one-to-one corresponding to the detection machine 12. When the transfer component 100 and the transfer component 220 are arranged on the detection platform 300 of a detection machine 12 at the same time, the transfer component 100 of the detection machine 12 can be used to receive the workpiece transferred by the transfer component 220 of the feeding machine 11 or the upstream detection machine 12, and transfer the workpiece to the transfer component 210; the transfer component 220 of the detection machine 12 can receive the workpiece transferred by the transfer component 210 of the detection machine 12, and transfer the workpiece to the transfer component 100 of another detection machine 12 located downstream, or to the unloading machine 13.

[0069] Please refer to FIG. 8. In an embodiment, at least one of the feeding machine 11 and the unloading machine 13 is provided with a tray conveying assembly 500. The tray conveying assembly 500 includes a lifting component 510 and a moving component 520. The lifting component 510 is used to carry and convey multiple trays 20 stacked with each other to a first station 501. The moving component 520 is used to convey a tray 20 at the first station 501 to a second station 502 for loading or unloading workpieces. Taking the tray conveying assembly 500 used in the feeding machine 11 as an example, a full load tray 20 can be filled at the lifting component 510. The full load tray 20 moves to the first station 501 under the driving of the lifting component 510. Moreover, the tray 20 at the first station 501 moves to the second station 502 under the driving of the moving component 520. It can be understood that the second station 502 can be a position facilitating the workpiece to be taken away by the feeding handling structure 600. That is, through the cooperation of the lifting component 510 and the moving component 520, the workpiece can be automatically conveyed to a position facilitating the workpiece to be taken away, thereby facilitating automatic feeding.

[0070] When the tray conveying assembly 500 is used in the unloading machine 13, an empty tray 20 can be filled at the lifting component 510. The empty tray 20 moves to the first station 501 under the driving of the lifting component 510. Moreover, the empty tray 20 at the first station 501 can move to the second station 502 under the driving of the moving component 520. The second station 502 can be a position facilitating the workpiece to be loaded into the tray 20 by the unloading handling structure 700.

[0071] Referring to FIGS. 8 and 9, in an embodiment, the tray conveying assembly 500 further comprises a stand 530 provided with a longitudinal rail 531, a transverse rail 532 and a magazine 533, the jacking member 510 is configured to carry the trays 20 stacked along the reference direction S, and the jacking member 510 is slidably coupled with the longitudinal rail 531 along the reference direction S to jack up any tray 20 to the first station 501. Since the trays 20 are stacked along the reference direction S and the jacking member 510 is jacked up along the reference direction S, the jacking member 510 is capable of jacking up any tray 20 to the first station 501. The material moving member 520 is slidably coupled with the transverse rail 532, and the material moving member 520 is configured to carry the tray 20 to move between the first station 501 and the second station 502. The magazine 533 is located above the first station 501, and the magazine 533 is provided with an inlet 533a, a projection of the inlet 533a on a plane where the first station 501 is located along the reference direction S coincides with the first station 501. The jacking member 510 is configured to jack the tray 20 into the magazine 533 from the inlet 533a. Since the projection of the inlet 533a coincides with the first station 501, after the jacking member 510 conveys the tray 20 to the first station 501, the material moving member 520 can not only take away the tray 20, but also further jack up the tray 20 to store the tray 20 in the magazine 533.

[0072] In the tray conveying assembly 500 described above, since the material moving member 520 is capable of carrying the tray 20 to move between the first station 501 and the second station 502, when the tray 20 completes taking or filling the workpieces at the second station 502, the material moving member 520 can carry the tray 20 back to the first station 501. The tray 20 at the first station 501 can be jacked into the magazine 533 under the action of the jacking member 510 to complete the unloading of the tray 20. Thus, through the cooperation of the material moving member 520 and the jacking member 510, not only the loading of the tray 20 can be achieved, but also the recycling and unloading of the tray 20 can be achieved, and the structure is simple and compact.

[0073] Referring to FIG. 8, in an embodiment, the jacking member 510 comprises a jacking table 510a and a jacking driver 510b, the jacking table 510a is configured to place the tray 20, and the jacking driver 510b is connected with the jacking table 510a to drive the jacking table 510a to jack up the tray 20 along the reference direction S.

[0074] Further, as shown in FIG. 9, the stand 530 further comprises a material placing plate 536. The jacking table 510a comprises a jacking plate 511, a connecting rod 512 and a connecting plate 513, the jacking plate 511 and the connecting plate 513 are respectively located on two sides of the material placing plate 536, and the connecting rod 512 penetrates the material placing plate 536 to be connected between the jacking plate 511 and the connecting plate 513. The longitudinal rail 531 is located on the same side of the material placing plate 536 as the connecting plate 513, and the connecting plate 513 and the longitudinal rail 531 are in sliding fit. Compared with directly arranging the longitudinal rail 531 on the side of the material placing plate 536 facing the first station 501, such arrangement can simplify the structure of the material tray conveying assembly 500 on the side of the material placing plate 536 facing the first station 501, thereby facilitating the arrangement of the material moving component 520.

[0075] Referring to FIG. 10, in an embodiment, the hopper 533 is provided with a plurality of bearing members 534 on the bottom thereof in the reference direction S, and a plurality of supporting blocks 535 are rotatably arranged on the bearing members 534 to open or block the inlet 533a. The supporting blocks 535 are driven to switch from the blocking state to the open state when the jacking component 510 jacks the material tray 20 into the inlet 533a along the reference direction S. In this way, when the jacking component 510 jacks the material tray 20 into the inlet 533a, the material tray 20 can automatically enter the hopper 533. The supporting blocks 535 are used to switch from the open state to the blocking state or remain in the blocking state when the material tray 20 in the hopper 533 is pressed downward. Thus, when the jacking component 510 no longer jacks, the material tray 20 can press the supporting blocks 535 to automatically close them.

[0076] Further, referring to FIG. 10, in an example, the supporting block 535 comprises a rotating portion 535a and a beak portion 535b arranged eccentrically with the rotating portion 535a. In the blocking state, the beak portion 535b at least partially extends into the inlet 533a to block the inlet 533a and support the material tray 20 in the hopper 533. When the jacking component 510 jacks the material tray 20 to lift the beak portion 535b, the beak portion 535b will rotate around the rotating portion 535a to allow the material tray 20 to enter the hopper 533. When the material tray 20 enters the hopper 533 and the jacking component 510 retreats, the material tray 20 in the hopper 533 can press the beak portion 535b downward based on gravity, so that the beak portion 535b returns to the blocking state.

[0077] Further, the hopper 533 can further be provided with a reset member 535c, which is elastically connected between the bearing member 534 and the supporting block 535 to elastically push the supporting block 535 to return to the blocking state. The reset member 535c can be used to push the beak portion 535b to rotate around the rotating portion 535a to return to the blocking state. The reset member 535c can be a compression spring.

[0078] In one embodiment, the beak 535b is inclined to the side of the first station 501 so that the lifting member 510 gradually lifts the beak 535b to rotate.

[0079] Referring to FIG. 9, in one embodiment, the material moving member 520 includes a moving table 520a and a chuck structure 520b for picking up the tray 20 and moving the tray 20. The chuck structure 520b is arranged on the moving table 520a, and the chuck structure 520b moves with the moving table 520a between the first station 501 and the second station 502. The moving table 520a and the chuck structure 520b can be respectively slidably connected with the cross rail 532 to improve the stability of movement.

[0080] As shown in FIGS. 11 and 12, the chuck structure 520b is provided with a clearance 521 for the tray 20 to pass through. The chuck structure 520b includes a linkage 522, a support plate 523, and a push block 524, and the linkage 522 is connected between the support plate 523 and the push block 524. Two support plates 523 are respectively arranged on two sides of the clearance 521, and two push blocks 524 are respectively arranged on two other opposite sides of the clearance 521. At least one support plate 523 can move towards the other support plate 523 to lift the tray 20 and drive the two push blocks 524 to move towards each other. In this way, the chuck structure 520b can clamp the tray 20 and move the tray 20 by a simple structure.

[0081] Further, the chuck structure 520b includes a base plate 525 provided with a first sliding groove 525a and a second sliding groove 525b, and the first sliding groove 525a extends along the movement direction of the support plate 523. The linkage 522 is slidably arranged in the first sliding groove 525a and connected with the support plate 523, so that when the support plate 523 moves, the linkage 522 can slide along the first sliding groove 525a.

[0082] The second sliding groove 525b extends along the sliding direction of the push block 524, and the push block 524 is slidably arranged in the second sliding groove 525b, so that the second sliding groove 525b can guide and limit the movement of the push block 524.

[0083] The linkage 522 is provided with a linkage hole 522a in one of the push blocks 524, and is provided with a matching column 524a in the other. The matching column 524a penetrates the linkage hole 522a, and the matching column 524a and the two side hole walls of the linkage hole 522a facing each other are in sliding fit. The extension direction of the two side hole walls of the linkage hole 522a facing each other intersects with the extension direction of the first sliding groove 525a and the extension direction of the second sliding groove 525b. Since the hole walls of the linkage hole 522a are obliquely arranged, when the linkage 522 is driven by the support plate 523 to move along the first sliding groove 525a, the hole walls of the linkage hole 522a can convert the driving force into driving force along the second sliding groove 525b to drive the push block 524 to move. Thus, linkage clamping and linkage positioning are achieved.

[0084] In one embodiment, the chuck structure 520b further comprises a chuck driver 520c connected with one of the support plates 523, and the chuck driver 520c is used to drive the support plate 523 to move towards or away from the other support plate 523. For example, as shown in FIG. 12, when the support plate 523 is driven by the chuck driver 520c to move towards the other support plate 523, the linkage 522 moves along the first sliding groove 525a. At this time, through the cooperation of the linkage hole 522a and the matching column 524a, the push block 524 can move along the second sliding groove 525b to cooperate with the support plate 523 to clamp the tray 20.

[0085] Further, the support plate 523 can move along the first direction S1, and the push block 524 can move along the second direction S2, and the first direction S1 intersects with the second direction S2. Further, the first direction S1 can be perpendicular to the second direction S2.

The feeding machine 11 comprises at least one tray conveying assembly 500, and after the tray conveying assembly 500 feeds the tray 20 to the second station 502, the feeding and carrying assembly can carry the workpiece to the transfer component 100. The transfer component 100 can receive the workpiece and then deliver it to the transfer component 210, which can carry the workpiece to the detection range of each detection module 400 for detection. Subsequently, the transfer component 210 can deliver the workpiece to the transfer component 210 of another detection machine arranged adjacently. The above-mentioned action of the transfer component 100 can be repeated between each detection machine 12 until the workpiece is delivered to the last detection machine 12 upstream of the discharging machine 13, and the transfer component 210 of the detection machine 12 delivers the workpiece to the discharging and carrying structure 700. Thereafter, the discharging and carrying structure 700 can fill the workpiece in the tray 20 at the second station 502 in the tray conveying assembly 500. When the filling of the tray 20 at the second station 502 in the discharging machine 13 is completed, the transfer component 520 carries the workpiece back to the first station 501. The full tray 20 at the first station 501 can enter the magazine 533 under the jacking of the jacking component 510 to complete the discharging.
