DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0030] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0032] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, 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 implementation method.

[0034] At present, in the production line of processing, the products to be processed are usually transferred by transfer devices such as manipulators, so that the products are moved to different stations. For example, the manipulator can be set to slide along the horizontal rail to transfer the workpiece from one of the stations to another station arranged horizontally. Alternatively, the manipulator can be set to slide along the horizontal rail and the vertical rail to transfer the workpiece from one of the stations to another higher station. However, if there is still a height limit at the two stations, there is insufficient space in the height direction at this time, and the vertical rail cannot be arranged, making it difficult for the manipulator to transfer the workpiece. For example, a defect detection machine includes a feeder and a detection machine, and the feeder is used to detect and transfer the workpiece to be inspected. Please refer to Figure 1, the feeder includes a silo 2 and a supporting structure 3, the silo 2 is arranged above the supporting structure 3, the supporting structure 3 is provided with a station 3a to be picked up, and the outlet of the silo 2 is opened below to face the supporting structure 3. At this time, by controlling the opening and closing of the silo 2 and coordinating the lifting and lowering movement of the supporting structure 3, the material tray in the silo 2 can be transferred to the to-be-picked station 3a. Furthermore, the manipulator 4 can move horizontally between the silo 2 and the supporting structure 3, and the manipulator 4 can grab the workpiece on the material tray at the to-be-picked station 3a, and drive the workpiece to move horizontally to achieve loading. For the above-mentioned loading scheme, since the manipulator 4 moves horizontally between the silo 2 and the supporting structure 3, the two are clamped up and down, so that there is not enough space between the two to set a vertical guide rail. At this time, it is difficult for the manipulator 4 to directly transfer the workpiece to another station at a height position. Similarly, the detection machine includes a transplanting structure and a detection module. The detection module is mounted above the transplanting structure. The transplanting structure is used to receive the workpiece transferred by the manipulator 4 and drive the workpiece to move into the detection field of view of the detection module. Due to the height limit of the detection module, it is also difficult to set a vertical guide rail for the transplanting structure.

[0035] It needs to be further explained that, in conjunction with Figure 2, at this time, the manipulator 4 has moved out of the space formed by the silo 2 and the supporting structure 3. Although the manipulator 4 has space for vertical movement at this time, it should be emphasized that the manipulator 4 needs to move in the space formed by the silo 2 and the supporting structure 3, which determines that it is difficult to set the manipulator 4 to have a large range of movement in the vertical direction. In other words, as shown in Figure 2, if a vertical guide rail is set to support the manipulator 4 to slide vertically outside the above-mentioned clamping space, it is obvious that the vertical guide rail will restrict the manipulator 4 at this time, so that the manipulator 4 cannot return to the above-mentioned clamping space again. The above-mentioned space formed by the silo 2 and the supporting structure 3 is shown in Figures 1 and 2, marked with K.

[0036] In order to solve the above problems, the present application provides a material transfer component, which can be used in a detection machine. The material transfer component includes a lifting component and a picking component, and the lifting component receives and lifts the workpiece. The picking component includes a first bracket and a first picking structure, and the first picking structure is rotatably matched with the first bracket. The first picking structure can be rotated relative to the first bracket to face down, so as to face the lifting component and pick up the workpiece on the lifting component. Since the lifting component can lift the workpiece, the manipulator can place the workpiece on the lifting component at a lower height position, and the lifting component then lifts the workpiece to a higher height position for the picking component to pick up. Further, the first picking structure can also be rotated relative to the first bracket to face up, so that on the one hand, the height position of the workpiece can be further changed with a simple structure, and on the other hand, the orientation of the workpiece can be changed so that the workpiece faces up for easy processing. It should be noted that Figures 1 and 2 are only examples of one of the actual situations of "the workpiece changes in height when it is transferred to another station, and the two stations before and after the transfer also have height limits". The material transfer device provided in each embodiment of the present application is not limited to the above-mentioned defect detection machine. The material transfer assembly provided in the present application and the detection device and detection equipment used in the material transfer assembly are described in detail below in conjunction with the specification and the drawings in the specification.

[0037] Please refer to FIG3 , an embodiment of the present application provides a detection device 1, which includes an upstream transfer device 10, a detection device 20 and a downstream transfer device 30, and the detection device 20 can be arranged between the upstream transfer device 10 and the downstream transfer device 30. The upstream transfer device 10 is used to transfer the workpiece to the detection device 20, and the downstream transfer device 30 is used to receive the workpiece transferred by the detection device 20.

[0038] Taking the transfer of workpieces 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 also a height limit at the first station 11 and the second station 21. The detection device 20 includes a material transfer component 100, which can transfer the workpiece from the first station 11 to the second station 21 with a simple structure. Of course, the same applies to the transfer of the workpiece from the second station 21 to the first station 11.

[0039] Please refer to FIG. 4 . In one embodiment, the material transfer assembly 100 includes a lifting component 110 and a picking component 120. The lifting component 110 is provided with an intermediate transfer position 110a, and the intermediate transfer position 110a is used to receive the workpiece transferred by the upstream transfer device 10, that is, the intermediate transfer position 110a is used to receive the workpiece transmitted from the first workstation 11. The lifting component 110 can lift the workpiece in the intermediate transfer position 110a. The picking component 120 includes a first bracket 121 and a first picking structure 122. The first picking structure 122 is provided with a picking position 120a, and the first picking structure 122 is used to fix the workpiece at the picking position 120a. The first picking structure 122 is rotatably connected to the first bracket 121 around the first horizontal axis O1, and the picking position 120a is spaced apart from the first horizontal axis O1. The first picking structure 122 can rotate to a posture where the picking position 120a faces the intermediate transfer position 110a to pick up the workpiece.

[0040] In the 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 in the intermediate transfer position 110a. Therefore, the upstream transfer device 10 can place the workpiece in the intermediate transfer position 110a at a relatively low height, and the lifting component 110 lifts the workpiece to the expected height for the first picking structure 122 to pick up, so as to meet the requirements of transferring the workpiece. Furthermore, the picking position 120a of the first picking structure 122 is spaced from the first horizontal axis O1, so that during the rotation of the first picking structure 122 around the first horizontal axis O1, the orientation of the picking position 120a and the workpiece fixed on the picking position 120a will change (for example, from facing down as shown in FIG. 5 to facing up as shown in FIG. 6) to facilitate processing. At the same time, the picking position 120a of the first picking structure 122 is spaced from the first horizontal axis O1, so the height position of the picking position 120a can also be changed during the rotation of the first picking structure 122 around the first horizontal axis O1. In this way, the orientation adjustment and horizontal position adjustment of the workpiece can be achieved simultaneously through a simple structure.

[0041] It should be noted that the height described in the embodiments of the present application refers to the height in the direction of gravity when the material transfer component 100 is operating normally, and the level refers to the level perpendicular to the direction of gravity when the material transfer component 100 is operating normally.

[0042] It should be understood that this embodiment is described by taking the material transfer assembly 100 as one of the components of the detection device 20 as an example, in which case the second station 21 can be configured as a picking station 120a, and of course the second station 21 can also be configured as a station at other positions. In other embodiments, the material transfer assembly 100 can be provided as an independent transfer mechanism between the upstream transfer device 10 and the detection device 20.

[0043] In one embodiment, the detection device 20 further includes a base 200 and a processing component (not shown), and the processing component is mounted above the base 200 to facilitate processing of the workpiece. The processing component is mounted above the base 200 so that a height limit exists at the second station 21. As for the first station 11, as mentioned above, the space between the silo and the supporting structure can be such that a height limit exists at the first station 11.

[0044] It should be understood that, in order to facilitate the transfer of the workpiece 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. The present application uses a simple structure in which the first picking structure 122 rotates around the first bracket 121, which can not only move the workpiece from a relatively low intermediate position 110a to a relatively high position for easy detection, but also synchronously flip and change the direction of the workpiece, so as to facilitate processing by the processing component above.

[0045] Please refer to FIG. 3 and FIG. 4 . In one embodiment, the base 200 includes a base plate 210. The base plate 200 is recessed to form a receiving groove 220. The receiving groove 220 forms an opening 211 on the base plate 210. At least part of the structure of the lifting component 110 is disposed in the receiving groove 220, so that the lifting component 110 has a relatively low height position to receive the workpiece transferred by the upstream transfer device 10. The lifting component 110 can be exposed from the receiving groove 220 through the opening 211, so as to lift the workpiece at the intermediate transfer position 110a to a height position that is convenient for the first pickup structure 122 to pick up.

[0046] Please refer to FIG. 4 and FIG. 5. In one embodiment, the lifting component 110 and the picking component 120 are both disposed on the base 200. The detection device 20 further includes a driving platform 500, which is disposed on the base 200. The first bracket 121 includes a first side 121a and a second side 121b. The driving platform 500 is connected to the first side 121a to drive the first bracket 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, and the second side 121b is inclined relative to the first side 121a toward the lifting component 110, so that when the first bracket 121 is in the material picking position, the second side 121b extends outward from the driving platform 500 and extends into the area where the lifting component 110 is located. As shown in FIG. 5, at this time, the first bracket 121 is in the material picking position. When the first bracket 121 is in the material picking position, the second side 121b can extend into the area where the lifting component 110 is located, so that the first picking structure 122 disposed on the second side 121b can be aligned with the lifting component 110. In other words, when the first bracket 121 is in the material picking position, the orthographic projection of the first picking structure 122 on the base 200 and the lifting component 110 have an overlapping area.

[0047] It should be noted that the first pick-up structure 122 in the pick-up component 120, which is directly used to pick up the workpiece, is held up by the first bracket 121 and is roughly suspended in the air. Therefore, when the first pick-up structure 122 picks up the workpiece on the lifting component 110, it needs to move to the top of the lifting component 110. In this embodiment, the first bracket 121 is arranged to be tilted, so that when the first side 121a is located outside the area where the lifting component 110 is located, the second side 121b can be tilted and inserted into the area where the lifting component 110 is located, so as to support the first pick-up structure 122 to be suspended above the lifting component 110 to achieve the transfer of the workpiece.

[0048] Of course, in another embodiment, the driving mode for driving the picking component 120 to move can be changed so that the picking component 120 can move to a position across the top of the lifting component 110 to conveniently pick up the workpiece. For example, as shown in FIG7 , the first screw rod 5 can be arranged on both sides of the lifting component 110 using a linear mode driven by a screw rod. At this time, the movement of the first bracket 121 is not limited by the position of the lifting component 110, and can be conveniently moved to the top of the lifting component 110. Of course, other similar driving modes are the same and will not be described one by one.

[0049] Please refer to Figure 8. In one embodiment, the lifting component 110 includes a supporting plate 111 and a transfer fixture 112. A plurality of transfer fixtures 112 are arranged on the supporting plate 111, and the plurality of transfer fixtures 112 are respectively used to form a plurality of transfer positions 110a. At least one transfer fixture 112 can move in a direction close to or away from another transfer fixture 112 to adjust the spacing of the workpieces at the transfer position 110a, so that the detection device 20 can adapt to detect workpieces with different spacings. It is easy to understand that due to different specifications or types, there are also different spacings between workpieces on the tray. In this embodiment, the spacing of the workpieces is adjusted by the lifting component 110 to adapt to the spacing of the first picking structure 122, which can improve the compatibility and adaptability of the detection device 20.

[0050] Furthermore, the upstream transfer device 10 can transfer two workpieces at the same time in a single transfer. At this time, the number of transfer fixtures 112 can be 4, and the 4 transfer fixtures 112 are arranged linearly. The two transfer fixtures 112 located on the outermost sides can move toward the two in the middle, so as to adjust the distance between two adjacent workpieces. Of course, the number of transfer fixtures 112 is not limited to 4. According to the material transfer method of the upstream transfer device 10 and the actual needs, the transfer fixtures 112 can have other different numbers, such as 2, 6, 8 and 10. The transfer fixture 112 can fix the workpiece by vacuum adsorption. The transfer fixture 112 can be arranged at intervals along the horizontal longitudinal direction. See the label S3 in Figure 4 for the horizontal longitudinal direction. The horizontal longitudinal direction S3 is perpendicular to the vertical direction S1 and the lateral direction S2 mentioned below.

[0051] In one embodiment, the lifting component 110 includes a variable distance drive 114 , and the number of the variable distance drive 114 is multiple. One variable distance drive 114 is correspondingly connected between a transfer fixture 112 and a supporting plate 111 to drive the transfer fixture 112 to move in a direction close to another transfer fixture 112 .

[0052] Please refer to Figures 8 and 9. In one embodiment, the lifting component 110 further includes a connecting frame 113 and a driving structure 115. The driving structure 115 is disposed on the connecting frame 113 and connected to the supporting plate 111 to drive the supporting plate 111 to rise and fall. Since the plurality of transfer fixtures 112 are all disposed on the supporting plate 111, driving the supporting plate 111 to rise and fall can synchronously drive the plurality of transfer fixtures 112 to rise and fall.

[0053] Furthermore, the driving structure 115 includes a lifting driver 115a, a second screw rod 115b and a nut 115c, and the lifting component 110 also includes a bearing 116 and a guide rod 117. The bearing 116 is embedded in the connecting frame 113, the nut 115c is arranged on the inner ring of the bearing 116 and rotates with the bearing 116, the second screw rod 115b is passed through the nut 115c to engage with the nut 115c, and the end of the second screw rod 115b is connected to the supporting plate 111, and the lifting driver 115a drives the nut 115c to rotate to make the second screw rod 115b move axially, so as to realize the lifting and lowering of the supporting plate 111. There are multiple guide rods 117, and multiple guide rods 117 can be slidably passed through the connecting frame 113, and the ends of the guide rods 117 are connected to the supporting plate 111 to improve the stability of the lifting and lowering movement of the supporting plate 111. The lifting driver 115a can drive the nut 115c to rotate by belt transmission. The direction in which the lifting component 110 lifts the workpiece is shown as S1 in the accompanying drawings of the specification, where S1 is the vertical direction. The guide rod 117 and the second screw rod 115b can both extend along the vertical direction S1.

[0054] Please refer to FIG. 10 and FIG. 11. In one embodiment, the detection device 20 further includes a carrier 600, which is used to carry the workpiece. The carrier 600 is connected to the driving platform 500, and the driving platform 500 can drive the carrier 600 to move, so that the carrier 600 drives the workpiece to move to each processing component. The carrier 600 includes a second bracket 610 and a second pick-up structure 620, and the second pick-up structure 620 is provided with a second pick-up position 120a. The second pick-up structure 620 is rotatably connected to the second bracket 610 to rotate to face the pick-up component 120. The first bracket 121 is parallel to the rotation axis of the second bracket 610. The second bracket 610 is connected to the driving platform 500, and the driving platform 500 is used to drive the second bracket 610 and the first bracket 121 to move in the same direction. In addition, the first pick-up structure 122 is parallel to the rotation axis of the second pick-up structure 620. Therefore, in conjunction with FIG4 , the first picking structure 122 and the second picking structure 620 can rotate to face each other, and the second picking structure 620 can pick up the workpiece on the picking position 120a. By arranging the carrier 600 to replace the picking component 120 to carry the workpiece to the processing component, the time that a single batch of workpieces occupies the picking component 120 can be shortened. After the picking component 120 transfers the workpiece to the carrier 600, it can return to the lifting component 110 to pick up the next batch of workpieces, and the carrier 600 can drive the workpiece to move to the processing component, thereby improving the processing efficiency.

[0055] The direction in which the driving platform 500 drives the picking component 120 and the carrier 600 to move is the lateral direction. The number of the carriers 600 can be multiple, and the multiple carriers 600 are arranged at intervals in the lateral direction. The lateral direction is referred to as S2 in the accompanying drawings of the specification.

[0056] Please refer to Figures 10 and 11. In one embodiment, the first picking structure 122 includes a first frame 122a and a plurality of first fixtures 112b, and the first fixture 112b is used to fix the workpiece. The first frame 122a rotates with the first bracket 121 around the first horizontal axis O1, and the plurality of first fixtures 112b rotate with the first frame 122a around the first rotation axis O3, respectively, and the first horizontal axis O1 intersects with the first rotation axis O3. In other words, the plurality of first fixtures 112b can rotate synchronously around the first horizontal axis O1 to adjust the angle toward the processing component and improve the flexibility of processing. Similarly, the plurality of first fixtures 112b can also rotate around the first rotation axis O3 to adjust the posture of the workpiece within the processing range of the processing component and improve the flexibility of processing.

[0057] The second picking structure 620 includes a second frame 621 and a plurality of second fixtures 622, and the second fixtures 622 are used to fix the workpiece. The second frame 621 rotates with the second bracket 610 around the second horizontal axis O2, and the plurality of second fixtures 622 rotate with the second frame 621 around the second rotation axis O4, respectively, and the second horizontal axis O2 intersects with the second rotation axis O4. In other words, the plurality of second fixtures 622 can rotate synchronously around the second horizontal axis O2 to adjust the angle toward the processing component and improve the flexibility of processing. Similarly, the plurality of second fixtures 622 can also rotate around the second rotation axis O4 to adjust the posture of the workpiece within the processing range of the processing component and improve the flexibility of processing.

[0058] The first fixture 112b and the second fixture 622 may both fix the workpiece by vacuum adsorption.

[0059] In one embodiment, there are at least two material transfer assemblies 100, and at least two material transfer assemblies 100 are respectively disposed on opposite sides of the base 200. One material transfer assembly 100 is used to receive the workpiece transferred by the upstream transfer device 10, and the other material transfer assembly 100 can be used to transfer the workpiece to the downstream transfer device 30.

[0060] In one embodiment, the structure of the upstream transfer device 10 may be the same as the material loader of the defect detection machine shown in Figures 1 and 2. Alternatively, the upstream transfer device 10 and the downstream transfer device 30 may be configured in other forms as required.
