Detailed Implementation

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Currently, in processing production lines, robotic arms and other transfer devices are commonly used to move products to different workstations. For example, a robotic arm can slide along a horizontal guide rail to transfer a workpiece from one workstation to another horizontally positioned workstation. Alternatively, a robotic arm can slide along both horizontal and vertical guide rails to transfer a workpiece from one workstation to a higher workstation. However, if there are height limitations at both workstations, there may be insufficient space in the vertical direction to arrange a vertical guide rail, making it difficult for the robotic arm to transfer the workpiece. For example, a defect detection machine includes a feeder and an inspection machine. The feeder is used to inspect and transfer workpieces to be inspected. Referring to Figure 1, the feeder includes a hopper 2 and a support structure 3. The hopper 2 is arranged above the support structure 3, which has a pick-up station 3a. The outlet of the hopper 2 is located below and faces the support structure 3. At this point, by controlling the opening and closing of the hopper 2, and in conjunction with the lifting and lowering movement of the supporting structure 3, the tray inside the hopper 2 can be transferred to the pickup station 3a. Furthermore, the robotic arm 4 can move horizontally between the hopper 2 and the supporting structure 3. The robotic arm 4 can grasp the workpiece on the tray located at the pickup station 3a and move the workpiece laterally to achieve loading. For the above loading scheme, because the robotic arm 4 moves horizontally between the hopper 2 and the supporting structure 3, the two are clamped together vertically, resulting in insufficient space to install a vertical guide rail. Therefore, the robotic arm 4 cannot directly transfer the workpiece to a station at another height. Similarly, the inspection machine includes a transfer structure and an inspection module. The inspection module is mounted above the transfer structure, which receives the workpiece transferred by the robotic arm 4 and moves the workpiece into the inspection field of view of the inspection module. Due to the height limitation of the inspection module, it is also difficult to install a vertical guide rail on the transfer structure.

[0041] It needs further explanation. Referring to Figure 2, the robotic arm 4 has now moved out of the space formed by the clamping of the hopper 2 and the supporting structure 3. Although the robotic arm 4 now has space for vertical movement, it is important to emphasize that the robotic arm 4 needs to move within the space formed by the clamping of the hopper 2 and the supporting structure 3. This determines that it is difficult to set a large range of vertical movement for the robotic arm 4. In other words, as shown in Figure 2, if a vertical guide rail is provided to support the robotic arm 4 to slide vertically outside the clamping space, then the vertical guide rail will obviously restrict the robotic arm 4, making it difficult for the robotic arm 4 to return to the clamping space. The space formed by the clamping of the hopper 2 and the supporting structure 3 is referred to as K in Figures 1 and 2.

[0042] To address the aforementioned problems, this application provides a material transfer assembly that can be used in an inspection machine. The material transfer assembly includes a lifting component and a picking component. The lifting component receives and lifts a workpiece. The picking component includes a first support and a first picking structure. The first picking structure is rotatably coupled to the first support and can rotate relative to the first support to face downwards, thus picking up the workpiece from the lifting component. Because the lifting component can lift the workpiece, a robot can place the workpiece at a lower height position on the lifting component, which then lifts the workpiece to a higher height position for the picking component to pick up. Furthermore, the first picking structure can also rotate relative to the first support to face upwards, thereby both changing the height position of the workpiece with a simple structure and changing the orientation of the workpiece so that its face faces upwards for easier processing. It should be noted that Figures 1 and 2 are merely examples illustrating one actual situation where "the workpiece changes position in the height direction when transferred to another station, and there are height limits at both stations before and after the transfer." The material transfer device provided in the embodiments of this application is not limited to application in the aforementioned defect inspection machine. The following description, in conjunction with the specification and accompanying drawings, provides a detailed description of the material transfer assembly provided in this application, as well as the detection device and equipment used in the material transfer assembly.

[0043] Referring to Figure 3, one embodiment of this application provides a testing device 1, which includes an upstream transfer device 10, a testing device 20, and a downstream transfer device 30. The testing device 20 may be disposed between the upstream transfer device 10 and the downstream transfer device 30. The upstream transfer device 10 is used to transfer workpieces to the testing device 20, and the downstream transfer device 30 is used to receive the workpieces transferred by the testing device 20.

[0044] Taking the transfer of a workpiece between the upstream transfer device 10 and the detection device 20 as an example, the upstream transfer device 10 has a first station 11, and the detection device 20 has a second station 21. There is not only a height difference between the first station 11 and the second station 21, but each station also has a height limit. The detection device 20 includes a material transfer assembly 100, which can transfer the workpiece from the first station 11 to the second station 21 with a simple structure. Similarly, the transfer of the workpiece from the second station 21 to the first station 11 is also straightforward.

[0045] Referring to Figure 4, in one embodiment, the material transfer assembly 100 includes a lifting component 110 and a picking component 120. The lifting component 110 has a transfer position 110a, which is used to receive the workpiece transferred by the upstream transfer device 10, that is, the transfer position 110a is used to receive the workpiece from the first station 11. The lifting component 110 is capable of lifting the workpiece located at the transfer position 110a. The picking component 120 includes a first support 121 and a first picking structure 122. The first picking structure 122 has a picking position 120a, which is used to fix the workpiece at the picking position 120a. The first picking structure 122 is rotatably connected to the first support 121 about a first horizontal axis O1. The picking position 120a is spaced apart from the first horizontal axis O1. The first picking structure 122 can rotate to a position where the picking position 120a faces the transfer position 110a to pick up the workpiece.

[0046] In the aforementioned material transfer assembly 100, the intermediate transfer position 110a is used to receive the workpiece transferred by the upstream transfer device 10, and the lifting component 110 can lift the workpiece located at the intermediate transfer position 110a. Thus, the upstream transfer device 10 can place the workpiece at the intermediate transfer position 110a at a lower height, and the lifting component 110 lifts the workpiece to the expected height for the first pick-up structure 122 to pick it up, thereby meeting the requirements for workpiece transfer. Furthermore, the pick-up position 120a of the first pick-up structure 122 is spaced apart from the first horizontal axis O1. Therefore, during the rotation of the first pick-up structure 122 around the first horizontal axis O1, the orientation of the pick-up position 120a and the workpiece fixed on the pick-up position 120a will change (for example, from facing down as shown in Figure 5 to facing up as shown in Figure 6), to facilitate processing. Meanwhile, the pickup position 120a of the first pickup structure 122 is spaced apart from the first horizontal axis O1. Therefore, when the first pickup structure 122 rotates around the first horizontal axis O1, the height position of the pickup position 120a can also be changed. With this configuration, the orientation and horizontal position adjustment of the workpiece are realized synchronously through a simple structure.

[0047] It should be noted that the height mentioned in the embodiments of this application refers to the height of the material transfer component 100 in the direction of gravity when it is operating normally, and the horizontal refers to the horizontal of the material transfer component 100 perpendicular to the direction of gravity when it is operating normally.

[0048] It should be understood that this embodiment uses the material transfer assembly 100 as one of the components of the detection device 20 for illustration. In this case, the second station 21 can be configured as the pickup station 120a. Of course, the second station 21 can also be configured as a station in other locations. In other embodiments, the material transfer assembly 100 can be set as an independent transfer mechanism between the upstream transfer device 10 and the detection device 20.

[0049] In one embodiment, the detection device 20 further includes a base 200 and a processing component (not shown). The processing component is mounted above the base 200 to facilitate the processing of the workpiece. The mounting of the processing component above the base 200 creates a height limit at the second station 21. As for the first station 11, as mentioned above, the height limit at the first station 11 can be created by the space between the hopper and the supporting structure.

[0050] It should be understood that, to facilitate the transfer of workpieces by the upstream transfer device 10, the lifting component 110 has a relatively low height position, while the processing component is mounted on the base 200 and has a relatively high height position. This application, through a simple structure where the first pickup structure 122 rotates around the first support 121, not only enables the workpiece to move from a relatively low intermediate position 110a to a relatively high position for inspection, but also allows for simultaneous rotation to change the orientation of the workpiece, facilitating processing by the upper processing component.

[0051] Referring to Figures 3 and 4, in one embodiment, the base 200 includes a substrate 210, and the base 200 has a recessed receiving groove 220, which forms an opening 211 in the substrate 210. At least a portion of the lifting member 110 is disposed within the receiving groove 220, so that the lifting member 110 has a relatively low height position to receive the workpiece transferred by the upstream transfer device 10. The lifting member 110 can be exposed through the opening 211 in the receiving groove 220 to lift the workpiece at the intermediate position 110a to a height position for the first pickup structure 122 to pick up.

[0052] Referring to Figures 4 and 5, in one embodiment, both the lifting component 110 and the picking component 120 are disposed on the base 200. The detection device 20 also includes a drive platform 500, which is disposed on the base 200. The first support 121 includes a first side 121a and a second side 121b. The drive platform 500 is connected to the first side 121a to drive the first support 121 to move, so that the picking component 120 can carry the workpiece to the location of the processing component. The first picking structure 122 is connected to the second side 121b. The second side 121b is inclined relative to the first side 121a towards the direction of the lifting component 110, so that when the first support 121 is in the picking position, the second side 121b extends out of the solid area of ​​the drive platform 500 and into the area where the lifting component 110 is located. As shown in Figure 5, the first support 121 is in the picking position at this time. When the first support 121 is in the material-picking position, the second side 121b can extend into the area where the lifting member 110 is located, so that the first picking structure 122 provided on the second side 121b can be aligned with the lifting member 110. In other words, when the first support 121 is in the material-picking position, the orthographic projection of the first picking structure 122 on the base 200 overlaps with the lifting member 110.

[0053] It should be noted that the first picking structure 122, which is directly used to pick up the workpiece in the picking component 120, is supported by the first bracket 121 and is in a state of being approximately suspended. Therefore, when the first picking structure 122 picks up the workpiece on the lifting component 110, it needs to move to be directly above the lifting component 110. In this embodiment, the first bracket 121 is set at an angle, so that when the first side 121a is outside the area where the lifting component 110 is located, the second side 121b can be tilted into the area where the lifting component 110 is located to support the first picking structure 122 to be suspended above the lifting component 110, thereby realizing the transfer of the workpiece.

[0054] Of course, in another embodiment, the driving method for moving the picking component 120 can be changed, allowing the picking component 120 to move to a position above the lifting component 110 for convenient workpiece picking. For example, as shown in Figure 7, a linear method using a lead screw can be used, with the first lead screw 5 positioned on both sides of the lifting component 110. In this case, the movement of the first support 121 is not limited by the position of the lifting component 110, and it can easily move above the lifting component 110. Other similar driving methods are similar and will not be described in detail here.

[0055] Referring to Figure 8, in one embodiment, the lifting component 110 includes a support plate 111 and a transfer fixture 112. Multiple transfer fixtures 112 are disposed on the support plate 111, and each transfer fixture 112 is used to form multiple transfer positions 110a. At least one transfer fixture 112 can move towards or away from another transfer fixture 112 to adjust the spacing of the workpieces at the transfer position 110a, enabling the detection device 20 to adapt to detecting workpieces with various spacings. It is readily understood that the spacing of workpieces on the tray can vary due to differences in specifications or types. This embodiment adjusts the workpiece spacing using the lifting component 110 to match the spacing of the first pickup structure 122, thereby improving the compatibility and adaptability of the detection device 20.

[0056] Furthermore, the upstream transfer device 10 can transfer two workpieces simultaneously in a single transfer. In this case, the number of transfer fixtures 112 can be four, arranged linearly. The two outermost transfer fixtures 112 can move towards the two in the middle, thereby adjusting the spacing between adjacent workpieces. Of course, the number of transfer fixtures 112 is not limited to four. Depending on the material transfer method of the upstream transfer device 10 and actual needs, other different numbers of transfer fixtures 112 can be configured, such as two, six, eight, and ten. The transfer fixtures 112 can fix the workpieces using vacuum adsorption. The transfer fixtures 112 can be arranged at intervals along a horizontal longitudinal direction, as shown by reference numeral S3 in Figure 4. The horizontal longitudinal direction S3 is perpendicular to both the vertical direction S1 and the transverse direction S2, which will be mentioned below.

[0057] In one embodiment, the lifting component 110 includes a pitch actuator 114, and there are multiple pitch actuators 114. Each pitch actuator 114 is connected between a transfer fixture 112 and a support plate 111. The pitch actuator 114 drives the corresponding transfer fixture 112 to move closer to another transfer fixture 112.

[0058] Referring to Figures 8 and 9, in one embodiment, the lifting component 110 further includes a connecting frame 113 and a drive structure 115. The drive structure 115 is disposed on the connecting frame 113 and connected to the support plate 111, and drives the support plate 111 to rise and fall. Since multiple transfer fixtures 112 are disposed on the support plate 111, driving the support plate 111 to rise and fall can synchronously drive the multiple transfer fixtures 112 to rise and fall.

[0059] Furthermore, the drive structure 115 includes a lifting actuator 115a, a second lead screw 115b, and a nut 115c. The lifting component 110 also includes a bearing 116 and guide rods 117. The bearing 116 is embedded in the connecting frame 113, the nut 115c is located in the inner ring of the bearing 116 and rotates with the bearing 116, the second lead screw 115b passes through the nut 115c to mesh with the nut 115c, and the end of the second lead screw 115b is connected to the support plate 111. The lifting actuator 115a drives the nut 115c to rotate, causing the second lead screw 115b to move axially, thereby lifting and lowering the support plate 111. There are multiple guide rods 117, which are slidably passed through the connecting frame 113, and the ends of the guide rods 117 are connected to the support plate 111 to improve the smoothness of the lifting and lowering movement of the support plate 111. The lifting driver 115a can drive the nut 115c to rotate via belt drive. The lifting component 110 lifts the workpiece in the direction indicated by S1 in the attached drawing of the instruction manual. S1 is the vertical direction. The guide rod 117 and the second lead screw 115b can both extend in the vertical direction S1.

[0060] Referring to Figures 10 and 11, in one embodiment, the detection device 20 further includes a carrier 600 for carrying a workpiece. The carrier 600 is connected to a drive platform 500, which drives the carrier 600 to move, causing the carrier 600 to move the workpiece to various processing components. The carrier 600 includes a second support 610 and a second pickup structure 620, the second pickup structure 620 having a second pickup position 120a. The second pickup structure 620 is rotatably connected to the second support 610 to rotate to face the pickup component 120. The rotation axes of the first support 121 and the second support 610 are parallel. The second support 610 is connected to the drive platform 500, which drives the second support 610 and the first support 121 to move in the same direction. Furthermore, the rotation axes of the first pickup structure 122 and the second pickup structure 620 are parallel. Therefore, referring to Figure 4, the first pickup structure 122 and the second pickup structure 620 can rotate to face each other, and the second pickup structure 620 can pick up the workpiece on pickup position 120a. By setting the carrier 600 to replace the pickup component 120 in transporting the workpiece to the processing component, the time that a single batch of workpieces occupies the pickup component 120 can be shortened.

That is, the plurality of first fixtures 112b can rotate synchronously about the first horizontal axis O1 to adjust the angle toward the processing component, thereby improving the flexibility of the processing. Similarly, the plurality of first fixtures 112b can also rotate about the first rotating axis O3 to adjust the posture of the workpiece within the processing range of the processing component, thereby improving the flexibility of the processing.

[0063] The second pick-up structure 620 includes a second frame 621 and a plurality of second fixtures 622, which are used to fix the workpiece. The second frame 621 is rotatably engaged with the second support 610 about a second horizontal axis O2, and the plurality of second fixtures 622 are rotatably engaged with the second frame 621 about a second rotating axis O4, which intersects the second horizontal axis O2. That is, the plurality of second fixtures 622 can rotate synchronously about the second horizontal axis O2 to adjust the angle toward the workpiece, thereby improving the flexibility of the machining process. Similarly, the plurality of second fixtures 622 can also rotate about the second rotating axis O4 to adjust the posture of the workpiece within the machining range of the workpiece, thereby improving the flexibility of the machining process.

[0064] In one embodiment, when the first pickup structure 122 and the second pickup structure 620 rotate to face each other, the plurality of first rotating shafts O3 and the plurality of second rotating shafts O4 are arranged in parallel or overlapping manner in a one-to-one correspondence.

[0065] Both the first fixture 112b and the second fixture 622 can use vacuum adsorption to fix the workpiece.
