[0002] This application claims priority to Chinese patent application No. 2024212120906, filed on May 30, 2024, entitled "Testing Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of appearance inspection technology, and in particular to an inspection device. Background Technology

[0004] With the development of automation technology, the production, assembly and testing of various equipment can be carried out automatically using automated equipment.

[0005] Taking visual inspection as an example, since the shapes of various workpieces to be inspected are different, the inspection methods and procedures are also different. In order to fully meet the inspection requirements, traditional technologies often require setting up corresponding inspection equipment for different workpieces. However, such a setup can easily lead to poor equipment versatility and high inspection costs. Summary of the Invention

[0006] According to various embodiments of this application, an inspection device is provided. The inspection device includes a loading machine, an inspection machine, and an unloading machine arranged sequentially. The inspection device also includes a transfer component and a transfer component. The transfer component is disposed between the loading machine and the inspection machine for transferring workpieces. The transfer component is disposed between the inspection machine and the unloading machine for transferring the workpieces. At least two inspection machines are independently disposed between the loading machine and the unloading machine. Each inspection machine includes a transfer component. The transfer components of adjacent inspection machines can transfer workpieces to each other. The transfer component can also receive the workpieces transferred by the transfer component and can further transfer the workpieces to the transfer component.

[0007] In one embodiment, the transfer component includes a first frame and a first body rotatably disposed on the first frame. The first body can limit the workpiece on the bearing side of the first body. When the first body rotates, it can adjust the orientation of the bearing side to receive the workpiece transferred by the feeder and to transfer the workpiece to the transfer component.

[0008] In one embodiment, the first machine body includes a carrier, a first pusher and a second pusher. The carrier is rotatably connected to the first frame. The carrier side is disposed on the carrier and a positioning block protrudes from the carrier side. The first pusher and the second pusher are movably disposed on the carrier. The first pusher and the second pusher move in opposite directions toward the positioning block and toward the positioning block, respectively, to jointly clamp the workpiece.

[0009] In one embodiment, the inspection machine includes an inspection table and a plurality of inspection modules disposed on the inspection table. The transfer component is movably disposed on the inspection table to transport the workpiece to the inspection range of the inspection module. The transfer component is used to pick up the workpiece transferred by the transfer component. The transfer component is also used to transfer the workpiece to the transfer component of another inspection machine or the unloading machine.

[0010] In one embodiment, the transfer component includes a support and a pickup member. The support is disposed on the inspection table, and the pickup member is movably disposed on the support. The pickup member moves relative to the support in at least two intersecting directions. The pickup member is used to pick up the workpiece carried by the transfer component and transfer it to the unloading machine.

[0011] In one embodiment, the testing machine is detachably connected to at least one of the feeding machine, the unloading machine, and another adjacent testing machine.

[0012] In one embodiment, at least one of the loading machine and the unloading machine is provided with a tray conveying assembly. The tray conveying assembly includes a lifting component and a transferring component. The lifting component is used to carry and convey multiple trays stacked on top of each other to a first station. The transferring component is used to convey one of the trays at the first station to a second station for filling the workpiece or removing the workpiece from the tray.

[0013] In one embodiment, the tray conveying assembly further includes a frame with longitudinal rails, transverse rails, and a hopper. The lifting component is used to carry the trays stacked along a reference direction. The lifting component slides along the longitudinal rails along the reference direction to lift any one of the trays to the first station. The transferring component slides along the transverse rails and is used to transport the trays between the first station and the second station. The hopper is located above the first station and has an inlet. The projection of the inlet along the reference direction onto the surface where the first station is located coincides with the first station. The lifting component is used to push the tray into the hopper from the inlet.

[0014] In one embodiment, the hopper is provided with a support member and a support block at the bottom in the reference direction. A plurality of the support members are arranged at intervals along the circumferential direction of the inlet. The support block is rotatably disposed on the support member to open or block the inlet. When the lifting member pushes the material tray into the inlet along the reference direction, it drives the support block to switch from a blocked state to an open state. The support block is used to switch from the open state to the blocked state or remain in the blocked state when pressed down by the material tray in the hopper.

[0015] In one embodiment, the material transfer component includes a transfer table and a chuck structure. The chuck structure is disposed on the transfer table and moves with the transfer table between the first station and the second station. The chuck structure is used to pick up the material tray and drive the material tray to move. The transfer table and the chuck structure are respectively slidably engaged with the horizontal rail.

[0016] In one embodiment, the material transfer component includes a chuck structure that slides with the cross rail. The chuck structure has a clearance opening for the material tray to pass through. The chuck structure includes a linkage, a support plate, and a push block. The linkage is linked between the support plate and the push block. The two support plates are respectively located on opposite sides of the clearance opening. The two push blocks are respectively located on the other opposite sides of the clearance opening. At least one support plate can move towards the other support plate to lift the material tray and drive the two push blocks to move towards each other.

[0017] In one embodiment, the chuck structure includes a base plate with a first groove and a second groove. The first groove extends along the movement direction of the pallet, and the second groove extends along the sliding direction of the push block. A linkage member is slidably disposed in the second groove and connected to the pallet, and the push block is slidably disposed in the second groove. One of the linkage member and the push block has a linkage hole, and the other has a mating post. The mating post passes through the linkage hole and slides with the opposing side walls of the linkage hole. The extending directions of the opposing side walls of the linkage hole intersect the extending directions of both the first groove and the second groove.

[0018] In one embodiment, the pallet moves along a first direction, and the pusher moves along a second direction, the first direction intersecting the second direction.

[0019] In one embodiment, the first direction is perpendicular to the second direction.

[0020] In one embodiment, the lifting component includes a lifting platform and a lifting driver. The lifting platform is used to place the material tray, and the lifting driver is connected to the lifting platform to drive the lifting platform to lift the material tray along the reference direction. The upright also includes a material placement plate. The lifting platform includes a lifting plate, a connecting rod, and a connecting plate. The lifting plate and the connecting plate are located on opposite sides of the material placement plate. The connecting rod passes through the material placement plate to connect the lifting plate and the connecting plate. The longitudinal rail and the connecting plate are located on the same side of the material placement plate, and the connecting plate is slidably engaged with the longitudinal rail.

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] It should be further explained that the embodiments of this application will focus on the conveying of workpieces to illustrate how the testing equipment achieves high versatility. Therefore, as shown in Figure 1, in order to facilitate the understanding of workpiece conveying, in each embodiment, the side of the workpiece conveying path that is relatively closer to the loading side is referred to as the upstream side (the side indicated by SY in Figure 1), and the side of the workpiece conveying path that is relatively closer to the unloading side is referred to as the downstream side (the side indicated by XY in Figure 1).

[0043] Referring to Figures 1 and 2, an embodiment of the present application provides a testing device 10 including a feeder 11, a testing machine 12 and a discharge machine 13 arranged in sequence, with at least two testing machines 12 independently disposed between the feeder 11 and the discharge machine 13.

[0044] Referring to Figure 3, the inspection device 10 also includes a transfer component 100 and a transfer component 220. The transfer component 100 is located between the loading machine 11 and the inspection machine 12 for transferring workpieces, and the transfer component 220 is located between the inspection machine 12 and the unloading machine 13 for transferring workpieces. Each inspection machine 12 includes a transfer component 210, and the transfer components 210 of adjacent inspection machines 12 can transfer workpieces to each other. Simultaneously, the transfer component 210 can also receive workpieces transferred by the transfer component 100, and the transfer component 210 is also used to transfer workpieces to the transfer component 220.

[0045] The aforementioned testing equipment 10 includes at least two testing machines 12 independently positioned between the loading machine 11 and the unloading machine 13. Each testing machine 12 includes a transfer component 210 capable of transferring workpieces to adjacent testing machines 12. Therefore, adding or removing any testing machine 12 among multiple testing machines does not affect the overall conveying function of the testing equipment 10, thus improving its scalability. Furthermore, the transfer component 210 can also receive workpieces transferred by the transfer component 100 and transfer them to the transfer component 220. Thus, any testing machine 12 installed between the loading machine 11 and the unloading machine 13 can receive workpieces from the loading machine 11 and transfer them to the unloading machine 13. Consequently, any testing machine 12 can be added as an independent expansion module between the loading machine 11 and the unloading machine 13 without hindrance to expand the testing station; or it can be freely removed. This setup allows for the addition or removal of testing machines 12 according to different testing needs, eliminating the need to design separate testing lines for each different product and improving the scalability and versatility of the testing equipment 10.

[0046] As shown in Figure 2, in one embodiment, the feeding machine 11 includes a feeding platform 11a, the inspection machine 12 includes an inspection platform 300, and the unloading machine 13 includes an unloading platform 13a. The transfer component 100 can be located on either the feeding platform 11a or the upstream inspection platform 300, or the transfer component 100 can be installed on both simultaneously. Similarly, the transfer component 220 can be located on either the downstream inspection platform 300 or the unloading platform 13a, or the transfer component 220 can be installed on both simultaneously. For ease of explanation, the following embodiments will be described using the example where both the transfer component 100 and the transfer component 220 are located on the inspection platform 300. The same principle applies to other cases, and therefore will not be repeated.

[0047] In one embodiment, at least one of the following three components—the testing machine 12, the feeding machine 11, the unloading machine 13, and another adjacent testing machine 12—is detachably connected. In other words, adjacent testing machines 12 are detachably connected, the testing machine 12 is detachably connected to the feeding machine 11, and the testing machine 12 is detachably connected to the unloading machine 13. This configuration improves the flexibility of expanding the various component modules included in the testing equipment 10.

[0048] Furthermore, the testing equipment 10 also includes a connecting structure (not shown in the figure, the same below), which is detachably connected between adjacent testing machines 12. For example, the connecting structure includes a connector (not shown in the figure, the same below) and two threaded locking parts (not shown in the figure, the same below). The two ends of the connector are detachably connected to two adjacent testing machines 12 through the two threaded locking parts. Similarly, a connecting structure can also be used to achieve a detachable connection between the testing machine 12 and the feeding machine 11, and between the testing machine 12 and the unloading machine 13. Of course, the detachable connection method can also be set to other forms according to needs, such as snap-fit ​​connection, pin insertion fixation, etc., which will not be described in detail here.

[0049] In one embodiment, as shown in FIG2, the loading machine 11 may include a loading and conveying structure 600 for transferring workpieces to the transfer component 100. The unloading machine 13 may include an unloading and conveying structure 700 for receiving workpieces transferred by the inspection machine 12.

[0050] Furthermore, the transfer component 100 can be used to position the picked-up workpiece to improve the positional accuracy of the workpiece fed by the feeder 11, thereby facilitating improved inspection results. Similarly, the transfer component 220 can be used to position the picked-up workpiece to improve its positional accuracy, thereby facilitating unloading and loading.

[0051] Furthermore, the number of inspection machines 12 between the loading machine 11 and the unloading machine 13 can be 2, 3, 4, or 5, etc., and can be set according to actual needs, without limitation here. Moreover, the inspection methods of the inspection machines 12 are not limited in the embodiments of this application. As shown in Figure 3, for example, the inspection machine 12 may include a vision inspection module to perform visual inspection of the workpiece. At the same time, each inspection machine 12 can adopt the same inspection method, or at least one inspection machine 12 can have a different inspection method than the others. In actual application, it can be set according to needs, and will not be elaborated further here.

[0052] Referring to Figures 3 to 5, in one embodiment, the transfer component 100 includes a first frame 110 and a first body 120, with the first body 120 rotatably mounted on the first frame 110. The first body 120 can limit the workpiece to its bearing side 121. When the first body 120 rotates, it can adjust the orientation of the bearing side 121 to receive the workpiece transferred by the feeder 11 and to transfer the workpiece to the transfer component 210. As shown in Figure 4, it is easy to understand that the transfer component 100 is located between the feeder 11 and the inspection machine 12. Therefore, for the transfer component 100, the feeder 11 and the inspection machine 12 are located relatively upstream and relatively downstream, respectively. Thus, the first body 120 can rotate the workpiece to face upstream and downstream, facilitating the transfer of the workpiece from the feeder 11 to the inspection machine 12.

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

[0054] In one embodiment, the bearing side 121 is provided with a limiting structure (not shown in the figure, the same below). When the feeder 11 places the workpiece on the bearing side 121, the limiting structure can limit the workpiece so that the workpiece can rotate with the first machine body 120.

[0055] Referring to Figures 5 and 6, in one embodiment, the first machine body 120 includes a support body 122, a first pusher 123, and a second pusher 124. The support body 122 is rotatably connected to the first frame 110. A support side 121 is disposed on the support body 122, and a positioning block 125 protrudes from the support side 121. The first pusher 123 and the second pusher 124 are movably disposed on the support body 122. The first pusher 123 and the second pusher 124 move in opposite directions toward and away from the positioning block 125 to jointly clamp the workpiece. By pushing the workpiece from different directions by the first pusher 123 and the second pusher 124, the workpiece can be pushed to the expected position, i.e., the workpiece can be positioned. On the other hand, the first pusher 123 and the second pusher 124 can also jointly clamp the workpiece to limit its movement, allowing the workpiece to rotate with the first machine body 120.

[0056] It should be noted that the first pusher 123 and the second pusher 124 can be used as part of a limiting structure to limit and fix the workpiece. Alternatively, in other embodiments, the first pusher 123 and the second pusher 124 are only used for positioning the workpiece, and the transfer component 100 may also be provided with a pickup structure (not shown in the figure, the same below), which stably limits and fixes the workpiece on the bearing side 121 of the first body 120. The pickup structure may be, for example, a vacuum adsorption pickup or an electromagnetic adsorption pickup.

[0057] It should be further explained that the transmission component 100 may be equipped with multiple drivers, which are respectively connected to the first pusher 123 and the second pusher 124 to drive the first pusher 123 and the second pusher 124 to move. Alternatively, the first pusher 123 and the second pusher 124 may be connected by a linkage structure (not shown in the figure, the same below), in which case the driver can drive one of the first pusher 123 and the second pusher 124 to drive the other to move synchronously.

[0058] Referring to Figure 3, in one embodiment, the inspection machine 12 further includes multiple inspection modules 400, all of which are disposed on the inspection table 300. Referring to Figures 4 and 7, an inspection machine 12 may include multiple transfer components 210, which are movably disposed on the inspection table 300 to transport workpieces to the inspection range of the inspection modules 400. The transfer components 210 are used to pick up workpieces transferred by the transfer component 100, and the transfer components 210 are also used to transfer workpieces to the transfer component 210 of another inspection machine 12 or the unloading machine 13.

[0059] Please continue to refer to Figures 4 and 7. In one embodiment, the testing station 300 is provided with a transfer platform 310, and multiple transfer components 210 are connected to the transfer platform 310. The transfer platform 310 can drive each transfer component 210 to move.

[0060] It is understandable that, while meeting the requirements for workpiece transfer and inspection, the inspection machine 12 may be configured to include only one transfer component 210.

[0061] Further, the transfer component 210 may include a second frame 211 and a second body 212, with the second body 212 rotatably connected to the second frame 211. The second body 212 has a transfer side 212a, which can limit the workpiece on the transfer side 212a. When the second body 212 rotates relative to the second frame 211, it can adjust the angle of the transfer side 212a toward the detection module 400. That is, when the second body 212 rotates relative to the second frame 211, it can adjust the angle of the workpiece toward the detection module 400 to facilitate sufficient detection of the workpiece. The second body 212 includes a transfer carrier 212b and a plurality of pick-up fixtures 212c disposed on the transfer carrier 212b. The plurality of pick-up fixtures 212c are spaced apart and used to fix the workpiece. The transfer side 212a is disposed on the transfer carrier 212b, and the plurality of pick-up fixtures 212c are all disposed on the transfer side 212a of the transfer carrier 212b. It is understandable that when the second body 212 rotates relative to the second frame 211, the transfer side 212a can also be oriented upstream or downstream.

[0062] As shown in Figure 4, further, the second body 212 can rotate relative to the second frame 211 about the second axis O2 to switch between upstream and downstream directions. The pick-up fixture 212c can rotate relative to the transfer carrier 212b about the third axis O3. The second axis O2 intersects the third axis O3. Thus, after the transfer component 210 moves the workpiece to the detection module 400, it can drive the second body 212 to rotate and / or the pick-up fixture 212c to rotate, so that the workpiece is within the detection range of the detection module 400 at different angles and postures, improving the comprehensiveness of the detection.

[0063] In one embodiment, the picking fixture 212c can be configured to pick up the workpiece in a specific way according to the different types, shapes and materials of the workpiece, such as vacuum adsorption picking, magnetic picking or snap-fit ​​picking.

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

[0065] Referring to Figure 4, in one embodiment, the transfer component 220 includes a support 221 and a pickup component 222. The support 221 is disposed on the inspection table 300, and the pickup component 222 is movably disposed on the support 221. The pickup component 222 moves relative to the support 221 in at least two intersecting directions. The pickup component 222 is used to pick up the workpiece carried by the transfer component 210 and transfer it to the unloading machine 13.

[0066] Furthermore, the support frame 221 can adopt a gantry structure to support the pickup component 222. The support frame 221 includes longitudinal beams 221a and crossbeams 221b. The two longitudinal beams 221a are respectively located on both sides of the transfer platform 310, and the crossbeams 221b span the transfer platform 310 and slide in engagement with the longitudinal beams 221a. The pickup component 222 is located on the crossbeams 221b and slides in engagement with them. Thus, by sliding the crossbeams 221b relative to the longitudinal beams 221a, and by sliding the crossbeams 221b of the pickup component 222, the position of the pickup component 222 can be adjusted to the desired position.

[0067] Regarding the transfer of workpieces between the transfer component 100 and the transfer component 210, referring to Figures 4, 5, and 7, it is easy to understand that both the first body 120 and the second body 212 are rotatable, and can be rotated to a face-to-face position (i.e., the bearing side 121 and the transfer side 212a are distributed facing each other). At this time, the transfer component 100 picks up one side of the workpiece, and the transfer component 210 can approach the transfer component 100 and pick up the other side of the workpiece that is set opposite to it, thereby realizing the transfer of the workpiece.

[0068] It should be noted that the transfer component 100 is not limited to being located between the feeding machine 11 and the upstream inspection machine 12. There can be multiple transfer components 100, with each transfer component 100 corresponding to one inspection machine 12 located upstream of the inspection machine 12. Similarly, the transfer component 220 is not limited to being located between the downstream inspection machine 12 and the unloading machine 13. There can be multiple transfer components 220, with each transfer component 220 corresponding to one inspection machine 12 located downstream of the inspection machine 12. When a testing machine 12 has both a transfer component 100 and a transfer component 220 on its testing table 300, the transfer component 100 of the testing machine 12 can be used to receive workpieces transferred by the loading machine 11 or the transfer component 220 of the upstream testing machine 12, and transfer the workpieces to the transfer component 210; the transfer component 220 of the testing machine 12 can receive workpieces transferred by the transfer component 210 of the testing machine 12, and transfer the workpieces to the transfer component 100 of another downstream testing machine 12, or to the unloading machine 13.

[0069] Referring to Figure 8, in one embodiment, at least one of the loading 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 transferring component 520. The lifting component 510 is used to carry and convey a plurality of trays 20 stacked on top of each other to a first station 501. The transferring component 520 is used to transfer a tray 20 at the first station 501 to a second station 502 for filling workpieces or removing workpieces from the tray 20. Taking the tray conveying assembly 500 used for the loading machine 11 as an example, a full-load tray 20 can be filled into the lifting component 510, and the full-load tray 20 moves to the first station 501 under the drive of the lifting component 510. And, the tray 20 at the first station 501 moves to the second station 502 under the drive of the transferring component 520. Understandably, the second station 502 can be a position where the loading and transporting structure 600 can easily remove the workpiece. In other words, with this configuration, the lifting component 510 and the transferring component 520 can workpieces can be automatically transported to a position that is easy to pick up, thus facilitating automated loading.

[0070] The same principle applies when the tray conveying assembly 500 is used in the unloading machine 13. An empty tray 20 can be loaded onto the lifting component 510, and the empty tray 20 moves to the first station 501 under the drive of the lifting component 510. Furthermore, the empty tray 20 at the first station 501 can move to the second station 502 under the drive of the material transfer component 520. The second station 502 can be a position that facilitates the unloading and handling structure 700 to load the workpiece onto the tray 20.

[0071] Referring to Figures 8 and 9, in one embodiment, the tray conveying assembly 500 further includes a support frame 530, which is provided with a longitudinal rail 531, a transverse rail 532, and a hopper 533. A lifting member 510 is used to support trays 20 stacked along a reference direction S. The lifting member 510 slides along the longitudinal rail 531 along the reference direction S to lift any tray 20 to the first station 501. Since the trays 20 are stacked along the reference direction S, and the lifting member 510 lifts along the reference direction S, the lifting member 510 can lift any tray 20 to the first station 501. A transferring member 520 slides along the transverse rail 532 and is used to transport the tray 20 between the first station 501 and the second station 502. The hopper 533 is located above the first station 501. The hopper 533 has an inlet 533a, the projection of the inlet 533a onto the surface of the first station 501 along the reference direction S coincides with the first station 501. The lifting component 510 is used to push the tray 20 into the hopper 533 through the inlet 533a. Since the projection of the inlet 533a coincides with the first station 501, after the lifting component 510 transports the tray 20 to the first station 501, it can not only be picked up by the transfer component 520, but also further lifted to store the tray 20 into the hopper 533.

[0072] In the aforementioned tray conveying assembly 500, since the material transfer component 520 can carry the tray 20 between the first station 501 and the second station 502, when the tray 20 completes the removal or loading of workpieces at the second station 502, the material transfer component 520 can carry the tray 20 back to the first station 501. The tray 20 at the first station 501 can be pushed into the hopper 533 by the lifting component 510, completing the unloading of the tray 20. Thus, through the cooperation of the material transfer component 520 and the lifting component 510, not only can the loading of the tray 20 be realized, but also the unloading of the tray 20 can be realized, resulting in a simple and compact structure.

[0073] Referring to Figure 8, in one embodiment, the lifting component 510 includes a lifting platform 510a and a lifting driver 510b. The lifting platform 510a is used to place the feed tray 20, and the lifting driver 510b is connected to the lifting platform 510a to drive the lifting platform 510a to lift the feed tray 20 along the reference direction S.

[0074] Further, as shown in Figure 9, the upright 530 also includes a material placement plate 536. The lifting platform 510a includes a lifting plate 511, a connecting rod 512, and a connecting plate 513. The lifting plate 511 and the connecting plate 513 are located on opposite sides of the material placement plate 536, and the connecting rod 512 passes through the material placement plate 536 to connect the lifting plate 511 and the connecting plate 513. The longitudinal rail 531 and the connecting plate 513 are located on the same side of the material placement plate 536, and the connecting plate 513 and the longitudinal rail 531 are in sliding fit. Compared to directly placing the longitudinal rail 531 on the side of the material placement plate 536 facing the first station 501, this arrangement simplifies the structure of the material tray conveying assembly 500 on the side of the material placement plate 536 facing the first station 501, thereby facilitating the arrangement of the material transfer component 520.

[0075] Referring to Figure 10, in one embodiment, the hopper 533 has a support member 534 and a support block 535 at its bottom in the reference direction S. Multiple support members 534 are spaced apart along the circumferential direction of the inlet 533a. The support block 535 is rotatably mounted on the support member 534 to open or close the inlet 533a. When the lifting member 510 pushes the tray 20 into the inlet 533a along the reference direction S, it drives the support block 535 to switch from a closed state to an open state. Thus, when the lifting member 510 pushes the tray 20 into the inlet 533a, the tray 20 can automatically enter the hopper 533. The support block 535 is used to switch from an open state to a closed state, or remain in a closed state, when the tray 20 is pressed down in the receiving hopper 533. Therefore, when the lifting member 510 stops lifting, the tray 20 can press down on the support block 535 to automatically close it.

[0076] Further, referring to Figure 10, in one example, the support block 535 includes a rotating part 535a and a beak part 535b eccentrically disposed with respect to the rotating part 535a. In the blocked state, the beak part 535b extends at least partially into the inlet 533a to block the inlet 533a and support the tray 20 within the hopper 533. When the lifting component 510 drives the tray 20 to lift the beak part 535b, the beak part 535b will rotate around the rotating part 535a to allow the tray 20 to enter the hopper 533. When the tray 20 enters the hopper 533 and the lifting component 510 retracts, the tray 20 within the hopper 533 can press down on the beak part 535b based on gravity, causing the beak part 535b to return to the blocked state.

[0077] Furthermore, the hopper 533 may also be equipped with a reset member 535c, which is elastically connected between the bearing member 534 and the support block 535 to elastically push the support block 535 back to the blocked state. The reset member 535c may be a pusher beak portion 535b, causing the beak portion 535b to rotate around the rotating portion 535a and return to the blocked state. The reset member 535c may be a compression spring.

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

[0079] Referring to Figure 9, in one embodiment, the material transfer component 520 includes a transfer stage 520a and a chuck structure 520b. The chuck structure 520b is used to pick up the material tray 20 and drive the material tray 20 to move. The chuck structure 520b is disposed on the transfer stage 520a and moves with the transfer stage 520a between the first station 501 and the second station 502. The transfer stage 520a and the chuck structure 520b can respectively slide in engagement with the horizontal rail 532 to improve the smoothness of movement.

[0080] As shown in Figures 11 and 12, the chuck structure 520b has a recess 521 through which the feed tray 20 passes. The chuck structure 520b includes a linkage 522, a support plate 523, and a pusher block 524. The linkage 522 is linked between the support plate 523 and the pusher block 524. The two support plates 523 are respectively located on opposite sides of the recess 521, and the two pushers 524 are respectively located on the other opposite sides of the recess 521. At least one support plate 523 can move towards the other support plate 523 to lift the feed tray 20, and in turn, drive the two pushers 524 to move towards each other. Thus, the chuck structure 520b, with its simple structure, can clamp the feed tray 20 and drive its movement.

[0081] Furthermore, the chuck structure 520b includes a base plate 525, which has a first slide groove 525a and a second slide groove 525b. The first slide groove 525a extends along the movement direction of the support plate 523. The linkage member 522 is slidably disposed in the first slide groove 525a and connected to the support plate 523. Therefore, when the support plate 523 moves, it can drive the linkage member 522 to slide along the first slide groove 525a.

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

[0083] One of the linkage member 522 and the push block 524 is provided with a linkage hole 522a, and the other is provided with a mating post 524a. The mating post 524a passes through the linkage hole 522a and slides in contact with the opposing side walls of the linkage hole 522a. The extending directions of the opposing side walls of the linkage hole 522a intersect the extending directions of the first slide groove 525a and the second slide groove 525b. Since the wall of the linkage hole 522a is inclined, after the linkage member 522 is driven by the support plate 523 to move along the first slide groove 525a, the wall of the linkage hole 522a can convert the driving force into a driving force along the second slide groove 525b to drive the push block 524 to move. Thus, linkage clamping and linkage positioning are realized.

[0084] In one embodiment, the chuck structure 520b further includes a chuck driver 520c, which is connected to one of the pallets 523. The chuck driver 520c drives the pallet 523 to move closer to or away from the other pallet 523. For example, as shown in FIG12, when the pallet 523 moves closer to the other pallet 523 under the drive of the chuck driver 520c, the linkage 522 moves along the first slide groove 525a. At this time, through the engagement of the linkage hole 522a and the mating post 524a, the pusher 524 can move along the second slide groove 525b to cooperate with the pallet 523 in clamping the tray 20.

[0085] Furthermore, the pallet 523 can move along the first direction S1, and the pusher 524 can move along the second direction S2, where the first direction S1 and the second direction S2 intersect. Even further, the first direction S1 can be perpendicular to the second direction S2.

[0086] To facilitate understanding of the testing equipment 10 described in the various embodiments of this application, the general conveying of the workpiece to the testing equipment 10 is briefly described below. As shown in Figure 2, from upstream to downstream, the testing equipment 10 sequentially includes a loading machine 11, a transfer component 100, at least two testing machines 12, a transfer component 220, and a unloading machine 13. The loading machine 11 includes at least one tray conveying assembly 500. After the tray conveying assembly 500 loads the tray 20 to the second station 502, the loading and conveying assembly can transport the workpiece to the transfer component 100. After receiving the workpiece, the transfer component 100 can transfer it to the transfer component 210. The transfer component 210 can transport the workpiece to the corresponding testing range of each testing module 400 for testing. Subsequently, the transfer component 210 can transfer the workpiece to the transfer component 210 of another adjacent testing machine. The actions of the transfer components 100 described above can be repeated between each inspection machine 12 until the workpiece is transferred to the last inspection machine 12 upstream of the unloading machine 13. At this point, the transfer component 210 of that inspection machine 12 transfers the workpiece to the unloading conveying structure 700. Thereafter, the unloading conveying structure 700 can fill the workpiece into the tray 20 at the second station 502 in the tray conveying assembly 500. After the tray 20 at the second station 502 in the unloading machine 13 is filled, the transfer component 520 carries the workpiece back to the first station 501. The full tray 20 at the first station 501 can then be lifted into the hopper 533 by the lifting component 510 to complete the unloading process.

[0087] 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.
