TECHNICAL FIELD

[0002] With the development of electromechanical related technologies, more and more automated devices are applied in the fields of production and processing. For example, automatic conveying devices are used to automatically convey products. For various automated devices, the position of the product is particularly critical, which will affect whether the product can be accurately picked up and whether the product can be at the expected station to receive the action of the related device. Therefore, in the automated device, positioning devices are usually arranged at each processing station (such as detection station, material transfer station, etc.) to improve the position accuracy of the product.

DETAILED DESCRIPTION

[0029] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in combination with the drawings. In the following description, a large number of specific details are set forth in order 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 departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] In the description of the application, it should be understood that, if there are these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0031] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0033] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" of the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" of the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0034] 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.

[0035] See Figures 1 to 3 , Figure 1 An isometric schematic diagram of a positioning device provided in an embodiment of this application is shown. Figure 2 for Figure 1 An exploded view of the positioning device shown. Figure 3 for Figure 1 An exploded view of each positioning component in the positioning device shown. A positioning device 1a provided in one embodiment of this application includes a base frame 10 and positioning components 20. The base frame 10 supports a workpiece 2. The base frame 10 includes a support plate 11 for supporting the workpiece 2. The positioning directions of at least two positioning components 20 (i.e., the first direction S1 and the second direction S2 mentioned below) intersect. Furthermore, one of the at least two positioning components 20 is supported and positioned above the other. The positioning component 20 includes two sets of positioning structures 100 and a driving structure 200. The two sets of positioning structures 100 respectively pass through the support plate 11 to jointly push the workpiece 2. The driving structure 200 is connected to the positioning structures 100 to drive the positioning structures 100 to move and push the workpiece 2 to the desired position. The drive structure 200 includes a drive wheel 210 and a drive member 220. At least two drive wheels 210 are spaced apart along the positioning direction of their respective positioning components 20. The drive member 220 surrounds the at least two drive wheels 210 and is driven by the drive wheels 210 to rotate circumferentially. Taking the drive wheel 210 as a boundary, the drive member 220 includes two drive segments 220a with opposite directions of movement. The two drive segments 220a are respectively connected to different positioning structures 100 to drive the two sets of positioning structures 100 to move towards each other and away from each other along the positioning direction.

[0036] The positioning device 1a has at least two positioning assemblies 20, which are arranged in different directions to jointly position the workpiece 2 to the desired position. In addition, the at least two positioning assemblies 20 are arranged in a stacked and intersected manner, in which one is arranged above the other, so as to save space. Further, the transmission member 220 has two transmission sections 220a, which are respectively connected to the different positioning structures 100, so as to simultaneously drive the two groups of positioning structures 100 to move towards each other and away from each other in the direction. That is, compared with the prior art in which independent driving sources are respectively used to drive the different positioning structures 100 to move, the transmission member 220 can simultaneously drive the two groups of positioning structures 100 to move towards each other and away from each other, so as to position the workpiece 2 in the direction. In this way, the driving sources are saved, the space occupied by the driving structure 200 is reduced, and the space for the stacked and intersected positioning assemblies 20 is also saved, so as to facilitate the integrated distribution design of the positioning assemblies 20.

[0037] Further, the driving structure 200 provided by the embodiments of the present application drives the positioning structures 100 to move by using a belt transmission or a similar belt transmission, so that the driving part (i.e., the driving member 230 to be mentioned below) of the driving structure 200 is connected to the transmission wheel 210 at one end, and the transmission member 220 is driven to rotate in the circumferential direction, and the positioning structures 100 are driven to move. It can be understood that the at least two positioning assemblies 20 are arranged in an intersected manner, and each includes a movable positioning structure 100, so that the components included in the two positioning assemblies 20 are concentrated at the intersection (i.e., substantially at the central region) of the two positioning assemblies 20. The present application uses the above transmission mode, so that the driving part can be located at the edge region relative to the central region, and can reserve arrangement space and movement space for the central intersection of the two positioning assemblies 20 arranged in an intersected manner. In this way, the distribution of the internal components of the positioning device 1a is optimized, so that the positioning device 1a can meet the requirements of compact structure and sufficient movement and positioning.

[0038] It can be understood that the plurality of positioning assemblies 20 can be arranged in an X-shaped intersected and spaced stacked manner.

[0039] Please refer to Figure 3 , and combine Figure 2For the convenience of understanding and description, the following briefly introduces each structure included in the positioning assembly 20 and the connection relationship thereof: The positioning assembly 20 can be arranged on the base frame 10. The positioning assembly 20 includes a positioning structure 100 and a driving structure 200. The driving structure 200 is connected with the positioning structure 100 to drive the positioning structure 100 to move and position the workpiece 2. The driving structure 200 includes a driving member 230 and the transmission wheel 210 and the transmission member 220 as described above. The driving member 230 is connected with the transmission wheel 210 to drive the transmission wheel 210 to rotate. The transmission member 220 is wound around at least two transmission wheels 210 to rotate circumferentially under the driving of the transmission wheel 210. The driving member 230 can be connected with the transmission wheel 210 located at one end in the positioning direction to reserve arrangement space and movement space for the central intersection area. The positioning structure 100 is connected with the transmission member 220. When the transmission member 220 rotates circumferentially, it can drive the two groups of positioning structures 100 to move towards each other and move away from each other. The positioning structure 100 includes a connecting seat 110, a positioning member 120, and a sliding table 130. The connecting seat 110 is in transmission connection with the transmission member 220. The connecting seat 110 is in sliding fit with the base frame 10 through the sliding table 130. The positioning member 120 is arranged on the connecting seat 110 and penetrates the supporting plate 11. The positioning member 120 can move with the connecting seat 110 to push the workpiece 2, so that the workpiece 2 moves to the desired position.

[0040] Further, the connecting seat 110 includes a body part 110a and a pressing plate 110b. The pressing plate 110b cooperates with the body part 110a to clamp a region in the circumferential direction of the transmission member 220, so that the connecting seat 110 is in transmission connection with the transmission member 220. The positioning assembly 20 further includes a fixing seat 300. Two fixing seats 300 are arranged at intervals on the base frame 10. The two transmission wheels 210 are rotatably arranged on the two fixing seats 300. The transmission member 220 is wound around the outside of the two transmission wheels 210. The driving member 230 penetrates one of the fixing seats 300 and is in transmission connection with the transmission wheel 210 arranged on the fixing seat 300, so as to drive the transmission member 220 to rotate circumferentially through the transmission wheel 210. The transmission member 220 is configured as one of a transmission belt, a transmission chain, a transmission rope, and a transmission wire. Further, the transmission member 220 can be configured as a synchronous belt. The transmission wheel 210 can be configured as a synchronous wheel.

[0041] It should be noted that the following will also be mentioned that the positioning assembly 20 can be divided into a one-layer assembly 21 and a two-layer assembly 22, the components included in the one-layer assembly 21 will be prefixed with the prefix "one-layer", and the components included in the two-layer assembly 22 will be prefixed with the prefix "two-layer" to distinguish. For example, the transmission wheel 210 is divided into a one-layer transmission wheel 211 belonging to the one-layer assembly 21 and a two-layer transmission wheel 212 belonging to the two-layer assembly 22, the one-layer transmission wheel 211 and the two-layer transmission wheel 212 are both transmission wheels 210, so the description of the transmission wheel 210 in each embodiment of the present application is also applicable to the one-layer transmission wheel 211 and the two-layer transmission wheel 212 without contradiction. The same applies to other components, which will not be described one by one in each embodiment.

[0042] Please refer to Figures 4 to 7 , in combination Figure 3 In each embodiment of the present application, the positioning device 1a is described by taking two positioning assemblies 20 as an example. When the number of positioning assemblies 20 is more than two, the design can be adaptively adjusted according to the description of two positioning assemblies 20 in each embodiment, so the description will not be repeated in each embodiment.

[0043] As Figure 2 , the positioning assembly 20 is divided into a one-layer assembly 21 and a two-layer assembly 22, the one-layer assembly 21 positions the workpiece 2 in the first direction S1, and the two-layer assembly 22 positions the workpiece 2 in the second direction S2. The first direction S1 and the second direction S2 intersect. The one-layer assembly 21 and the two-layer assembly 22 are both arranged on the base frame 10, and the two-layer assembly 22 is arranged above the one-layer assembly 21 by being supported by the base frame 10. Therefore, the one-layer assembly 21 and the two-layer assembly 22 can be distributed in a staggered manner. Further, the one-layer assembly 21 and the two-layer assembly 22 are distributed in a staggered manner along the third direction S3.

[0044] Further, the first direction S1 can be perpendicular to the second direction S2. Further, the first direction S1, the second direction S2, and the third direction S3 can be perpendicular to each other.

[0045] Please continue to refer to Figure 1 and Figure 2 In one embodiment, the base frame 10 can include a base plate 12, a column 13, a support 14, and a support plate 11 as described above, the base plate 12 and the support plate 11 are arranged in a spaced manner, the column 13 is supported between the base plate 12 and the support plate 11, and the support 14 is arranged on the base plate 12 and between the base plate 12 and the support plate 11. The positioning assembly 20 is arranged on the base plate 12. Further, the base frame 10 further includes the support 14, the one-layer assembly 21 is arranged on the base plate 12, the support 14 is arranged on the base plate 12 and spans the one-layer assembly 21 in the second direction S2, and the two-layer assembly 22 is arranged on the support 14 and is staggered on the one-layer assembly 21.

[0046] Please refer to Figure 4 andFigure 5 , and Figure 3 In one embodiment, the positioning structure 100 of the first-tier assembly 21 is a first-tier positioning structure 101 including a first-tier positioning member 121 for contacting the workpiece 2. The positioning structure 100 of the second-tier assembly 22 is a second-tier positioning structure 102 including a second-tier positioning member 122 for contacting the workpiece 2. The two first-tier positioning structures 101 are respectively located at opposite sides of the second-tier positioning structure 102 in the first direction S1. The shortest distance between the first-tier positioning members 121 of the two first-tier positioning structures 101 is greater than the shortest distance between the second-tier positioning members 122 of the two second-tier positioning structures 102, so that the first-tier positioning structure 101 is used for positioning in the direction in which the workpiece 2 has a relatively long dimension, and the second-tier positioning structure 102 is used for positioning in the direction in which the workpiece 2 has a relatively short dimension. Since the second-tier assembly 22 is located above the first-tier assembly 21, and the two first-tier positioning structures 101 are respectively located at opposite sides of the second-tier positioning structure 102 in the first direction S1, the two first-tier positioning members 121 of the two first-tier positioning structures 101 have a minimum distance threshold when moving towards each other, i.e., cannot collide with the second-tier positioning structure 102 and the related support structure, due to the central blocking of the second-tier positioning structure 102 in the first direction S1. Thus, in this embodiment, the first-tier assembly 21 is configured for positioning in the direction in which the workpiece 2 has a relatively long dimension, so that the first-tier positioning structure 101 moves in a relatively large distance range, which can reduce the probability of collision between the first-tier positioning structure 101 and the second-tier positioning structure 102 and the related support structure. In contrast, the second-tier assembly 22 is relatively located above, and the movement of the second-tier positioning structure 102 is not limited by the first-tier assembly 21, so that the movement stroke of the second-tier positioning structure 102 can be more flexibly designed, and thus the shortest distance between the second-tier positioning members 122 of the two second-tier assemblies 22 can be configured to be smaller. For example, as described above, the second-tier positioning structure 102 is used for positioning in the direction in which the workpiece 2 has a relatively short dimension, so as to occupy a smaller space. In this embodiment, the positioning direction of the positioning assembly 20 is reasonably configured in correspondence with the length and width of the workpiece 2, so that the positioning device 1a is more targeted and effective when positioning the workpiece 2.

[0047] Further, since the second-tier assembly 22 is located above the first-tier assembly 21 by the support 14, in the first direction S1, the two first-tier positioning structures 101 can be located at opposite sides of the support 14, i.e., the two first-tier positioning structures 101 will be limited by the central blocking of the support 14 and the second-tier positioning structure in the first direction S1.

[0048] Further, the driving structure 200 of the first layer assembly 21 is a first layer driving structure, which is connected with the first layer positioning structure 101 to drive the first layer positioning structure 101 to move in the first direction S1. The driving structure 200 of the second layer assembly 22 is a second layer driving structure, which is connected with the second layer positioning structure 102 to drive the second layer positioning structure 102 to move in the second direction S2.

[0049] Referring to Figure 3 and Figure 4 In one embodiment, the transmission member 220 of the first layer assembly 21 is a first layer transmission member 221, and the transmission wheel 210 is a first layer transmission wheel 211. In the direction intersecting the first direction S1, the first layer positioning structure 101 is located at one side of the first layer transmission member 221. That is, the first layer transmission member 221 and the first layer transmission wheel 211 are arranged side by side with the first layer positioning structure 101. In this way, the size of the first layer assembly 21 in the first direction S1 is relatively reduced, so that the first layer positioning structure 101 can have a larger stroke range in the length direction of the workpiece 2, facilitating the positioning of the workpiece 2 in the length direction.

[0050] Further, the first layer positioning structure 101 comprises a first layer connecting seat 111 and a plurality of first layer positioning members 121 as described above. The first layer connecting seat 111 is in driving connection with the first layer transmission member 221, and the first layer positioning members 121 are arranged through the support plate 11 to abut against the workpiece 2. The plurality of first layer positioning members 121 are arranged on the first layer connecting seat 111 in the direction intersecting the first direction S1, so that the plurality of first layer positioning members 121 can move synchronously with the first layer connecting seat 111 to jointly contact and abut against one side of the workpiece 2, so as to move the workpiece 2 to the desired position in the first direction S1. In the direction intersecting the first direction S1, the first layer connecting seat 111 and the plurality of first layer positioning members 121 are distributed on the same side of the first layer transmission member 221, so that the first layer positioning structure 101 can have a larger stroke range in the length direction of the workpiece 2 in the limited space, facilitating the positioning of the workpiece 2 in the length direction.

[0051] Further, the number of the first layer positioning members 121 on a single first layer connecting seat 111 can be two. The two first layer positioning members 121 can be arranged on the first layer connecting seat 111 in the second direction S2. In the second direction S2, the first layer connecting seat 111 and the plurality of first layer positioning members 121 are distributed on the same side of the first layer transmission member 221.

[0052] Referring to Figure 5 and Figure 6In one embodiment, the two-layer positioning structure 102 comprises the two-layer connecting seat 112 and a plurality of two-layer positioning members 122 as described above, the two-layer positioning members 122 are arranged through the support plate 11 for pushing the workpiece 2, and the plurality of two-layer positioning members 122 are arranged on the two-layer connecting seat 112 to move synchronously with the two-layer connecting seat 112 along the second direction S2 to contact and push one side of the workpiece 2, so that the workpiece 2 moves to the desired position along the second direction S2.

[0053] Further, the transmission member 220 of the two-layer assembly 22 is a two-layer transmission member 222, and the two-layer connecting seat 112 is connected with the two-layer transmission member 222 to move along the second direction S2 under the driving of the two-layer transmission member 222. The plurality of two-layer positioning members 122 are arranged on the two-layer connecting seat 112 along a direction intersecting the second direction S2. Moreover, along the direction intersecting the second direction S2, the plurality of two-layer positioning members 122 are distributed on the opposite sides of the two-layer transmission member 222. That is, the middle region of the two-layer connecting seat 112 is used to connect the two-layer transmission member 222. In the present embodiment, the plurality of two-layer positioning members 122 are divided into two parts, and one part of the two-layer positioning members 122 is located on one side of the two-layer transmission member 222, and the other part is located on the other side of the two-layer transmission member 222 along the direction intersecting the second direction S2. Therefore, in the limited distribution space, the two parts of the two-layer positioning members 122 can have larger spacing sizes, so as to improve the pushing positioning effect of the two-layer positioning members 122 on the workpiece 2. That is, in the present embodiment, the two-layer assembly 22 is arranged compactly, and the positioning effect of the two-layer assembly 22 on the workpiece 2 is improved. It can be understood that in the present embodiment, the two-layer positioning structure 102, the two-layer transmission wheel 212 and the two-layer transmission member 222 are arranged along the second direction.

[0054] Further, the number of two-layer positioning members 122 on a single two-layer connecting seat 112 can be two. The two two-layer positioning members 122 can be arranged on the two-layer connecting seat 112 along the first direction S1 and distributed on the opposite sides of the two-layer transmission member 222. In this way, in the limited space along the first direction S1, the two two-layer positioning members 122 can have larger spacing.

[0055] Please refer to Figure 4 and Figure 6 In one embodiment, the base frame 10 is provided with a first sliding rail 16 and a second sliding rail 17, the first sliding rail 16 extends along the first direction S1, and the second sliding rail 17 extends along the second direction S2. Further, the first sliding rail 16 can be arranged on the base plate 12, and the one-layer positioning structure 101 is in sliding cooperation with the first sliding rail 16. The second sliding rail 17 can be arranged on the support frame 14, and the two-layer positioning structure 102 is in sliding cooperation with the second sliding rail 17.

Along the first direction S1, the first connecting seat 111a and the second connecting seat 111b are suspended on one side away from each other relative to the first sliding rail 16. The first layer sliding platform 131a is arranged on the side of the first connecting seat 111a close to the second connecting seat 111b and is slidingly connected with the first sliding rail 16, and the second layer sliding platform 131b is arranged on the side of the second connecting seat 111b close to the first connecting seat 111a and is slidingly connected with the first sliding rail 16. Therefore, when the first layer sliding platform 131a and the second layer sliding platform 131b move to the limit position along the first sliding rail 16 in the direction away from each other, the first connecting seat 111a and the second connecting seat 111b can be suspended on one side away from each other. Thus, within the limited length of the first sliding rail 16, the first connecting seat 111a and the second connecting seat 111b can have a larger spacing when moving away from each other, so as to position the workpiece 2 in the length direction of the workpiece 2. In short, the design can shorten the size of the first sliding rail 16 and simplify the structure of the base frame 10, i.e., the structure of the positioning device la, while ensuring the stroke range of the first layer positioning structure 101.

The shortest distance between the first layer positioning members 121 of the two groups of first layer assemblies 21 refers to the shortest distance between the first positioning rod 121a and the second positioning rod 121b.

[0059] Please continue to refer to Figure 7 In combination Figure 4In one embodiment, two transmission sections 220a of one layer transmission member 221 are arranged in the third direction S3.

The first connecting seat 111a is in sliding fit with the first section 16a, and the second connecting seat 111b is in sliding fit with the second section 16b, so that the first connecting seat 111a and the second connecting seat 111b are arranged in a staggered manner in the third direction S3, to correspond to the transmission sections 220a of one layer transmission member 221 arranged in the third direction S3.

The number of the third positioning rod 122a and the fourth positioning rod 122b can be two, and the two third positioning rods 122a are distributed on the opposite sides of the second layer transmission member 222 along a direction intersecting the second direction S2, and the two fourth positioning rods 122b are distributed on the opposite sides of the second layer transmission member 222 along a direction intersecting the second direction S2.

[0064] Referring to Figure 4 In an embodiment, the first layer assembly 21 further comprises a first layer fixing seat 310 arranged on the base plate 12. The two first layer transmission wheels 211 are rotatably arranged on the first layer fixing seat 310, and the first layer transmission member 221 is wound outside the two first layer transmission wheels 211. The driving structure 200 further comprises a first layer driving member 231 penetrating one of the first layer fixing seats 310 and being in transmission connection with the first layer transmission wheel 211 arranged on the first layer fixing seat 310, so as to drive the first layer transmission member 221 to rotate circumferentially through the first layer transmission wheel 211.

[0066] Referring to Figure 8 , and combining Figure 3 In an embodiment, the first layer driving member 231 is in transmission connection with the first layer positioning structure 101 through the first layer transmission wheel 211 and the first layer transmission member 221. The second layer driving member 232 is in transmission connection with the second layer positioning structure 102 through the second layer transmission wheel 212 and the second layer transmission member 222.

[0067] Referring to Figure 8In one embodiment, the substrate 12 is divided into multiple regions by the orthographic projections of the first-layer drive member 221 and the second-layer drive member 222 onto the substrate 12. The first-layer drive member 231 and the second-layer drive member 232 are located in non-adjacent regions. It is understood that the drive member 230 typically has a large structural size; therefore, arranging the two drive members 230 in non-adjacent regions reduces the probability of interference between components and achieves the purpose of making reasonable use of the mounting space on the substrate 12. The first-layer drive member 231 can be disposed on the substrate 12, and the second-layer drive member 232 can be disposed on the bracket 14. The aforementioned orthographic projection can be the projection of the first-layer drive member 221 and the second-layer drive member 222 onto the substrate 12 along a third direction S3. The region where the orthographic projection of the first-layer drive member 221 onto the substrate 12 is located is shown below.

A second-layer drive member 232 can be connected to a second-layer transmission wheel 212 located on the opposite lower side in the second direction S2, and is positioned to the left of the second-layer transmission wheel 212 in the first direction S1. In this case, the substrate 12 can be divided into four regions: upper left, lower left, upper right, and lower right. The first-layer drive member 231 can be distributed in the upper right region, and the second-layer drive member 232 can be distributed in the lower left region. Of course, the same principle applies to the first-layer drive member 231 and the second-layer drive member 232 being distributed in other non-adjacent regions, so it will not be described in detail here.

Figure 3 In one embodiment, the positioning member 120 includes a rod portion 120a and a rolling portion 120b, the rolling portion 120b rotating about the axis of the rod portion 120a. At least a portion of the structure of the rolling portion 120b extends outward from the side of the support plate 11 where the workpiece 2 is located, for rolling engagement with the workpiece 2 to push against the workpiece 2. This improves the smoothness of the positioning member 120 pushing against the movement of the workpiece 2.

The production equipment 1 comprises a feeding device 1b, the positioning device 1a, and a measuring device 1c, and the feeding device 1b, the positioning device 1a, and the measuring device 1c are sequentially arranged along the conveying direction K.
