Detailed implementation manners

[0026] To make the above objects, features, and advantages of the present application more apparent and understandable, the following describes the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand 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 departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0027] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the accompanying drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0028] In addition, if 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 quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. 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 specifically defined.

[0029] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0031] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate 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 intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0032] Refer to Figure 1 and Figure 2, in an embodiment of the present application, the positioning structure 10 is used to position a plurality of workpieces 2. The positioning structure 10 includes a positioning table 100, a first positioning component 200, and a driving structure 400. A plurality of positioning areas 102 are provided on the tabletop 111 of the positioning table 100, and the positioning areas 102 are used for placing the workpieces 2. The first positioning component 200 includes a plurality of first positioning members 210 and a plurality of second positioning members 220, and both the plurality of first positioning members 210 and the plurality of second positioning members 220 extend out of the tabletop 111. Along the first direction K1, the first positioning members 210 and the second positioning members 220 are alternately arranged at intervals in sequence. The adjacent and spaced-apart first positioning member 210, second positioning member 220, and the tabletop 111 enclose to form the positioning area 102. The driving structure 400 is connected to the first positioning component 200 to drive each first positioning member 210 to move synchronously along the first direction K1 and drive each second positioning member 220 to move synchronously along the first direction K1.

[0033] Both the above-mentioned first positioning member 210 and the second positioning member 220 extend out of the tabletop 111, and the first positioning member 210 and the second positioning member 220 are alternately arranged at intervals in sequence, so that the adjacent first positioning member 210 and the second positioning member 220 can enclose with the tabletop 111 to form the positioning area 102, and there are a plurality of positioning areas 102 on the tabletop 111. Moreover, the driving structure 400 can drive each first positioning member 210 to move synchronously and can drive each second positioning member 220 to move synchronously. Therefore, when the workpiece 2 is placed in the positioning area 102, the movement of the first positioning member 210 and the second positioning member 220 can push the workpiece 2 in each positioning area 102 to move, so that a plurality of workpieces 2 can be positioned simultaneously. With such a setting, the simultaneous positioning of a plurality of workpieces 2 is achieved through a simple structure. In addition, the driving structure 400 drives a plurality of first positioning members 210 to move synchronously and drives a plurality of second positioning members 220 to move synchronously, without configuring a separate driver for each positioning member, so the structure is simpler and more compact.

[0034] Such as Figure 2 , further, since the first positioning member 210 and the second positioning member 220 move in the first direction K1 to achieve the positioning of the workpiece 2, the positioning area 102 can be used to place workpieces 2 with different sizes in the first direction K1, and the positioning structure 10 can position workpieces 2 with different sizes in the first direction K1.

[0035] Please refer to Figures 1 to 3In one embodiment, the positioning structure 10 further includes a second positioning assembly 300, and the second positioning assembly 300 further includes a push bar 310 and a plurality of third positioning members 320, and the plurality of third positioning members 320 are arranged on the push bar 310, and the plurality of third positioning members 320 are arranged at intervals along the first direction K1 to correspond to each positioning area 102 respectively. A positioning bar 114 extending along the first direction K1 is provided on the table 111, and the driving structure 400 is connected to the push bar 310 to drive the push bar 310 to move toward or away from the positioning bar 114 along the reference direction M, so that the workpiece 2 is positioned in the second direction K2. The reference direction M is perpendicular to the first direction K1. In this way, through the first positioning assembly 200 and the second positioning assembly 300, multiple workpieces 2 can be completely positioned on the table 111.

[0036] See also Figure 1 and Figure 3 In one embodiment, the positioning platform 100 includes a support plate 110 and a stand 120, and the table surface 111 is the top surface of the support plate 110. The two stands 120 are supported on the bottom surface of the support plate 110 at intervals to form a receiving space 101 together with the support plate 110. The first positioning assembly 200 and the driving structure 400 are arranged in the receiving space 101, so that the positioning structure 10 is more compact as a whole and occupies less space.

[0037] like Figure 3 In one embodiment, the first positioning assembly 200 further includes a first carrier plate 230 and a second carrier plate 240, which are respectively connected to the driving structure 400 by transmission, so the driving structure 400 can drive the first carrier plate 230 and the second carrier plate 240 to move respectively. The first carrier plate 230 and the second carrier plate 240 are arranged on the side of the positioning platform 100 away from the table 111, and a plurality of first positioning members 210 are arranged on the first carrier plate 230, and a plurality of second positioning members 220 are arranged on the second carrier plate 240. Therefore, the driving structure 400 can make the plurality of first positioning members 210 move synchronously by driving the first carrier plate 230 to move; and the driving structure 400 can make the plurality of second positioning members 220 move synchronously by driving the second carrier plate 240 to move. The first positioning member 210 and the second positioning member 220 extend through the table 111 and extend beyond the table 111 to enclose and form the positioning area 102.

[0038] Furthermore, the first carrier plate 230 , the second carrier plate 240 and other related structures are arranged on the side of the positioning platform 100 away from the table 111 , which can reduce the space occupied on the table 111 and facilitate the table 111 to fully place the workpiece 2 .

[0039] Combination Figure 3The first carrier plate 230 and the second carrier plate 240 can be slidably matched with the positioning platform 100 to improve the stability of the movement of the first carrier plate 230 and the second carrier plate 240. Further, the bottom surface of the support plate 110 is provided with a slide rail 113, and the first carrier plate 230 and the second carrier plate 240 are respectively slidably matched with the slide rail 113. Of course, the first carrier plate 230 and the second carrier plate 240 can also be configured to movably penetrate the frame 120 to improve the stability of the movement of the two.

[0040] See also Figures 3 to 5 In one embodiment, the first carrier plate 230 and the second carrier plate 240 are stacked on the side of the positioning platform 100 away from the table 111, that is, the first carrier plate 230 and the second carrier plate 240 are stacked in the receiving space 101. In addition, the second carrier plate 240 is further away from the table 111. The first carrier plate 230 is provided with a clearance opening 233 for the second positioning member 220 to pass through, so that the second positioning member 220 can extend out of the table 111. It can be understood that when the first carrier plate 230 is further away from the table 111, the clearance opening 233 can be provided on the second carrier plate 240. In this embodiment, the first carrier plate 230 is provided with a clearance opening 233 so that the first carrier plate 230 will not block the second positioning member 220, so the first carrier plate 230 and the second carrier plate 240 can be arranged in a stacked manner. The first carrier plate 230 and the second carrier plate 240 are stacked and arranged, so that the distribution positions of the first carrier plate 230 and the second carrier plate 240 are stable, and the arrangement is simpler and easier.

[0041] At the same time, the opening 233 can also reduce the weight of the first carrier plate 230 or the second carrier plate 240 , thereby improving the portability of movement.

[0042] Of course, the first carrier plate 230 and the second carrier plate 240 are not limited to being distributed in a manner of stacking one another. For example, in another embodiment, the first carrier plate 230 and the second carrier plate 240 may be distributed on the same plane parallel to the table surface 111. At this time, the first carrier plate 230 may be provided with a first fork tine (not shown in the figure, the same below) extending along the first direction K1, and a plurality of first positioning members 210 are provided on the first fork tine. The second carrier plate 240 is provided with a second fork tine (not shown in the figure, the same below) also extending along the first direction K1, and a plurality of second positioning members 220 are provided on the second fork tine. The first fork tine and the second fork tine are arranged in a staggered manner in the second direction K2. With such a configuration, the movement of the first fork tine along the first direction K1 and the movement of the second fork tine along the first direction K1 will not interfere with each other. Regarding the distribution position of the first tine and the second tine, in short, regard the first tine as the left hand finger, and the second tine as the right hand finger. The distribution of the first tine and the second tine is similar to the left hand finger inserted into the gap between the right hand fingers. At this time, the right hand finger is also inserted into the gap between the left hand fingers, forming a staggered distribution.

[0043] In one embodiment, the pallet 110 is provided with a plurality of through holes 112, and the through holes 112 are strip-shaped holes extending along the first direction K1. The first positioning member 210 and the second positioning member 220 pass through the through holes 112 to extend out of the tabletop 111 through the through holes 112.

[0044] Please continue to refer to Figures 3 to 5 , in one embodiment, a plurality of first positioning members 210 are arranged in an array along the first direction K1 and the second direction K2. A plurality of second positioning members 220 are arranged in an array along the first direction K1 and the second direction K2. The first direction K1 intersects the second direction K2. The first positioning member 210 and the second positioning member 220 can move towards each other in the first direction K1 to position the workpiece 2. Then, it is further set that the first positioning member 210 and the second positioning member 220 are also distributed in the second direction K2, which can increase the number of parts where the first positioning member 210 and the second positioning member 220 contact the workpiece 2 and improve the stability of pushing the workpiece 2 to move towards the expected position. Of course, in another embodiment, it can be directly set that the parts of the first positioning member 210 and the second positioning member 220 extending out of the tabletop 111 extend along the second direction K2 to increase the contact area with the workpiece 2.

[0045] As Figure 2 shown, L1 marks the first positioning member 210 at the same position in the first direction K1, L2 marks the second positioning member 220 at the same position in the first direction K1, S1 marks the first positioning member 210 at the same position in the second direction K2, and S2 marks the second positioning member 220 at the same position in the second direction K2.

[0046] Furthermore, the included angle between the first direction K1 and the second direction K2 can be adaptively designed according to the outer contour of the workpiece 2. For example, when the outer shape of the workpiece 2 is rectangular, the first direction K1 and the second direction K2 can be perpendicular to each other, that is, at this time, the second direction K2 is parallel to the reference direction M. When the outer shape of the workpiece 2 is a non-rectangular parallelogram, the included angle between the first direction K1 and the second direction K2 can be set to an acute angle or an obtuse angle.

[0047] Please refer to Figures 4 to 6 , in one embodiment, the first carrier plate 230 includes a plurality of first ribs 231, and the first positioning member 210 is arranged on the first ribs 231. The second carrier plate 240 includes a plurality of second ribs 241, and the second positioning member 220 is arranged on the second ribs 241. One of the first ribs 231 and the second ribs 241 extends along the first direction K1, and the other extends along the second direction K2. Thus, as Figure 6After the first carrier plate 230 and the second carrier plate 240 are stacked, the first rib 231 and the second rib 241 form a cross-shaped network structure, which improves the stability of the first carrier plate 230 or the second carrier plate 240 and reduces the probability of bending in the middle of the rib.

[0048] For example, the second carrier plate 240 is farther from the tabletop 111 than the first carrier plate 230. As Figure 4 shown, the first rib 231 can extend along the first direction K1, and a plurality of first ribs 231 are arranged along the second direction K2, so that the plurality of first positioning members 210 provided on the first rib 231 are arranged in the array as described above. Moreover, the plurality of first ribs 231 are spaced apart along the second direction K2 to form an avoidance opening 233 for the second positioning member 220 to pass through. The first carrier plate 230 further includes a first side strip 232, and the first side strip 232 serially connects the ends of the plurality of first ribs 231 together, making the first carrier plate 230 generally in a grid shape. The first side strip 232 can be two.

[0049] The second rib 241 can extend along the second direction K2, and a plurality of second ribs 241 are arranged along the first direction K1, so that the plurality of second positioning members 220 provided on the second rib 241 are arranged in the array as described above. The second carrier plate 240 further includes a second side strip 242, and the second side strip 242 serially connects the ends of the plurality of second ribs 241 together, making the second carrier plate 240 generally in a grid shape to reduce the overall weight of the second carrier plate 240 and facilitate movement. The number of the second side strips 242 is two.

[0050] In one embodiment, the second carrier plate 240 further includes a reinforcing rib 243, and the reinforcing rib 243 extends along the first direction K1 and serially connects each second rib 241 to strengthen the structural strength of the second carrier plate 240 and reduce the probability of the middle of the second rib 241 sagging and bending due to weight.

[0051] Please refer to Figure 2 In one embodiment, when the avoidance opening 233 is formed by the interval between adjacent first ribs 231, the first positioning member 210 and the second positioning member 220 are arranged in a staggered manner in the second direction K2, so as to facilitate the second positioning member 220 to pass through the avoidance opening 233. At the same time, such an arrangement can also reduce the mutual interference of the movement of the first positioning member 210 and the second positioning member 220 in the first direction K1.

[0052] Of course, when the avoidance opening 233 is directly formed in the first rib 231 or formed in other ways, the first positioning member 210 and the second positioning member 220 can also be arranged at the same position in the second direction K2.

[0053] Please continue to refer to Figure 4 and Figure 5, in one embodiment, the first positioning member 210 includes a first rod portion 211 and a first contact portion 212. The first rod portion 211 passes through the through hole 112, and two ends of the first rod portion 211 are respectively connected to the first contact portion 212 and the first carrier plate 230. The first contact portion 212 extends out of the tabletop 111. The first contact portion 212 has a cylindrical outer surface to facilitate contacting workpieces 2 with various shapes.

[0054] Similarly, the second positioning member 220 includes a second rod portion 221 and a second contact portion 222. The second rod portion 221 passes through the through hole 112 and is connected to the second contact portion 222 and the second carrier plate 240. The second contact portion 222 extends out of the tabletop 111. The second contact portion 222 has a cylindrical outer surface to facilitate contacting workpieces 2 with various shapes.

[0055] Please refer to others Figure 6 , the first carrier plate 230 is provided with a plurality of first sliding platforms 234. The plurality of first sliding platforms 234 are arranged at intervals along the first direction K1 to slidably cooperate with the slide rail 113.

[0056] The second carrier plate 240 is provided with a plurality of second sliding platforms 244. The plurality of second sliding platforms 244 are also arranged at intervals along the first direction K1 to slidably cooperate with the slide rail 113.

[0057] Please refer to Figure 3 and Figure 7 , in one embodiment, the driving structure 400 includes a first driving member 410 and a second driving member 420. The first driving member 410 is used to drive the first positioning assembly 200 to move, and the second driving member 420 is used to drive the second positioning assembly 300 to move. Wherein, the first driving member 410 and the second driving member 420 can be arranged on the positioning table 100 or can be independently arranged relative to the positioning table 100 (for example, arranged on a supporting part such as the ground). The first driving member 410 includes a transmission belt 412 and at least two transmission wheels 413. The transmission belt 412 is wound around the outer circumferences of at least two transmission wheels 413. The first carrier plate 230 and the second carrier plate 240 are respectively connected to two sections of the transmission belt 412 with different movement directions. Thus, when the transmission belt 412 moves, it can drive the first carrier plate 230 and the second carrier plate 240 to move synchronously, eliminating the need to separately set up independent driving sources and simplifying the structure. Moreover, since the first carrier plate 230 and the second carrier plate 240 are respectively connected to two sections of the transmission belt 412 with different movement directions, when the transmission wheel 413 rotates, the first carrier plate 230 will move towards each other or away from each other.

[0058] Combined with Figure 8, the positioning table 100 further includes a support plate 130, and the support plate 130 is connected between the two vertical frames 120. The first driving member 410 further includes a first driver 411, and the first driver 411 is connected to one of the transmission wheels 413. The first driver 411 drives the transmission wheel 413 to rotate, so that the transmission belt 412 can move accordingly. The other transmission wheel 413 is rotatably arranged on the support plate 130.

[0059] Please continue to refer to Figures 3 to 5 , in one embodiment, the plate-like structure formed by connecting the first rib 231 and the first side strip 232 is denoted as the first plate body 235. The plate-like structure formed by connecting the second rib 241 and the second side strip 242 is denoted as the second plate body 245. The first connecting frame 236 is horizontally connected between the two outermost first ribs 231, and a part of the structure of the first connecting frame 236 has a gap with the first plate body 235 for the second carrier plate 240 to pass through. It can be understood that the first carrier plate 230 and the second carrier plate 240 are stacked on each other, and the first carrier plate 230 is farther from the first driving member 410 than the second carrier plate 240. Therefore, setting this gap can facilitate the connection between the first carrier plate 230 and the first driving member 410.

[0060] The second carrier plate 240 is provided with a second connecting frame 246, and the second connecting frame 246 is horizontally connected between the second side strips 242.

[0061] Please refer to Figure 8 , the first connecting frame 236 is provided with a first clamping plate 237, and the first clamping plate 237 is used for driving connection with the transmission belt 412. The second connecting frame 246 is provided with a second clamping plate 247, and the second clamping plate 247 is used for driving connection with the transmission belt 412.

[0062] Please refer to again Figure 8 , in one embodiment, the driving structure 400 further includes two position sensors 430. The two position sensors 430 are arranged on the positioning table 100 at intervals along the first direction K1, and the positions of the two position sensors 430 are adjustable in the first direction K1. The first carrier plate 230 or the second carrier plate 240 is provided with a trigger 201, and the trigger 201 is electrically connected to the first driving member 410 to stop the first driving member 410 from driving when any one of the position sensors 430 is triggered. That is to say, by adjusting the positions of the two position sensors 430 in the first direction K1, the movement limit positions of the first positioning member 210 and the second positioning member 220 are adjusted. Therefore, the positions of the two position sensors 430 can be adaptively adjusted according to the shape of different workpieces 2.

[0063] Please refer to Figure 7, in one embodiment, the driving structure 400 further includes a second driving component 420. The second driving component 420 is connected to the push bar 310 to drive the push bar 310 to move. The second driving component 420 includes a second driver 421 and a transmission frame 422. The transmission frame 422 is connected between the second driver 421 and the push bar 310 to drive the push bar 310 to move along the reference direction M. The second driver 421 is disposed in the receiving space 101. The third positioning member 320 is movably disposed on the table 111. The third positioning member 320 may also have a cylindrical outer surface.

[0064] Please refer to Figure 9 , the present application further provides a conveying device 1. The conveying device includes a handling structure 20 and the positioning structure 10 as described in each embodiment. The handling structure 20 is used to convey the workpiece 2 to the positioning structure 10 and / or convey the workpiece 2 from the positioning structure 10 to a designated area. For example, the workpiece 2 can be conveyed to the positioning structure 10 before the automatic conveying of the workpiece 2 so that the workpiece 2 has a determined position, which is convenient for improving the position accuracy during the automatic conveying of the workpiece 2. Or, after the conveying is completed, the workpiece 2 can be conveyed to the positioning structure 10 so that the workpiece 2 has a determined position, which is convenient for accurately loading the workpiece 2 onto a tray.
