[0062] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the convenience of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0063] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0064] Unless otherwise specified, the exemplary embodiments / examples shown will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various embodiments / examples can be additionally combined, separated, interchanged and / or rearranged.

[0065] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences can be performed in a different order than described. For example, two consecutively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same reference numerals denote the same components.

[0066] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there may be an intermediate component. However, when a component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have an intermediate component.

[0067] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "over", "higher", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the figures. In addition to the orientation depicted in the figures, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the figures is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0068] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. In addition, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus are used to explain the inherent deviations of measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0069] Figure 1 is a schematic structural diagram of a workpiece attitude transformation system according to an embodiment of the present disclosure.

[0070] As Figure 1 shown, the workpiece attitude transformation system of the present disclosure may include: a flipping device 100 and a positioning device 200; when the workpiece attitude transformation system of the present disclosure is in use, a workpiece on a production line can be transported to the flipping device 100 through a device such as a robotic arm. Thus, the flipping device 100 can hold the workpiece, and through the flipping action of the flipping device 100, the attitude of the workpiece is transformed.

[0071] Among them, the "flipping" described in the present disclosure does not merely refer to flipping the workpiece by 180°, but rather a flipping action that generates a preset angle is sufficient.

[0072] Figure 2Schematic structural diagram of the flipping device of the workpiece attitude transformation system according to an embodiment of the present disclosure. Figure 3 Schematic structural diagram of a partial structure of the flipping device of the workpiece attitude transformation system according to an embodiment of the present disclosure. Figure 4 Schematic structural diagram of another angle of a partial structure of the flipping device of the workpiece attitude transformation system according to an embodiment of the present disclosure.

[0073] As Figures 2 to 4 shown, the flipping device 100 of the present disclosure may include structures such as a lifting drive device 110, a sliding plate 120, a flipping drive device 130, a flipping plate 140, and a fixing plate 150.

[0074] Specifically, the lifting drive device 110 of the present disclosure can be fixed to the ground or to the workbench through a bracket or the like, and the lifting drive device 110 of the present disclosure is specifically a linear drive mechanism. For example, the lifting drive device 110 can be components such as a cylinder, a hydraulic cylinder, or an electric cylinder; in Figure 2 the implementation form shown, the lifting drive device 110 is preferably an electric cylinder.

[0075] The lifting drive device 110 is used to drive the sliding plate 120 to generate a vertical movement; that is to say, a first guide rail can be included on the side of the lifting drive device 110 of the present disclosure, and the first guide rail is arranged to extend in the vertical direction; at this time, a driving slider is slidably arranged on the first guide rail; when the lifting drive device 110 is in a working state, the driving slider can be driven to rise or fall. At the same time, the sliding plate 120 is fixed to the driving slider, and correspondingly, the sliding plate 120 can also generate a rising action or a falling action.

[0076] The flipping drive device 130 is arranged on the sliding plate 120, and the sliding plate 120 can drive the flipping drive device 130 to generate a lifting action synchronously.

[0077] In the present disclosure, a through hole is formed on the sliding plate 120, and the flipping drive device 130 is fixed to one side of the sliding plate 120. Preferably, the flipping drive device 130 and the lifting drive device 110 are located on the same side of the sliding plate 120; moreover, at least a part of the flipping drive device 130 can pass through the through hole of the sliding plate 120 and be located on the other side of the sliding plate 120.

[0078] More specifically, the axis of the output shaft of the flipping drive device 130 is horizontally arranged. In a preferred embodiment, the axis of the output shaft of the flipping drive device 130 is perpendicular to the sliding plate 120. The flipping drive device 130 of the present disclosure may include a flipping motor. Correspondingly, the output shaft of the flipping drive device 130 may be the output shaft of the flipping motor. On the other hand, the flipping drive device 130 of the present disclosure may include a flipping motor and a speed reducer driven by the flipping motor. At this time, the output shaft of the flipping drive device 130 is the output shaft of the speed reducer.

[0079] In a preferred embodiment, the flipping motor may be a servo motor, so that the workpiece pose transformation system of the present disclosure can have a relatively high flipping accuracy and good stability.

[0080] A connecting plate 131 is arranged on the output shaft of the flipping drive device 130. In the present disclosure, the connecting plate 131 is arranged substantially vertically, and through the arrangement of the connecting plate 131, the rotation axis of the output shaft of the flipping drive device 130 can be located at a position between the flipping plate 140 and the fixing plate 150. Thus, when the workpiece attitude transformation system of the present disclosure is in use, the flipping plate 140 and the fixing plate 150 have a relatively small turning radius, reducing the influence of the flipping plate 140 and the fixing plate 150 on other structures.

[0081] The flipping plate 140 is fixed to the connecting plate 131 and is arranged parallel to the rotation axis of the flipping drive device 130; moreover, there is a preset distance between the flipping plate 140 and the rotation axis, so that the flipping plate 140 has a preset turning radius.

[0082] As Figure 2 shown, the rotation axis of the flipping drive device 130 of the present disclosure is substantially located at the central position of the connecting plate 131. At this time, the flipping plate 140 is fixed to the lower end of the connecting plate 131.

[0083] Thus, when the flipping drive device 140 works, the flipping plate 140 is driven by the flipping drive device 130 to be able to flip a preset angle, or in other words, the flipping plate 140 is driven by the flipping drive device 130 to be able to rotate a preset angle, so that the workpiece after the pose transformation meets the requirements of the production line.

[0084] In a preferred embodiment, a pressure sensor 141 is arranged on the flipping plate 140, and an intermediate plate 142 is arranged on the pressure sensor 141; that is to say, the pressure sensor 141 of the present disclosure is arranged between the flipping plate 140 and the intermediate plate 142, so as to be able to detect the pressure applied by the intermediate plate 142 to the flipping plate 140 and prevent damage to the workpiece when picking and placing the workpiece.

[0085] Both ends of the intermediate plate 142 are provided with guiding structures 143. Specifically, the guiding structures 143 are provided at both ends of the intermediate plate 142 along the direction of the rotation axis of the flipping driving device 130, and the guiding structures 143 are arranged perpendicular to the flipping plate 140; that is to say, in Figure 2 and Figure 3 In the specific example shown, the flipping plate 140 is horizontally arranged, and correspondingly, the guiding structures 143 are vertically arranged.

[0086] In a specific embodiment, the guiding structure 143 can be a linear guide rail.

[0087] An intermediate slider 144 is arranged on the guiding structure 143. Correspondingly, the intermediate slider 144 is arranged to be able to slide along the guiding structure 143. Since one intermediate slider 144 is arranged on each guiding structure 143, correspondingly, the number of the intermediate sliders 144 in the present disclosure is two.

[0088] The fixing plate 150 is fixed to the intermediate slider 144. Thus, the fixing plate 150 in the present disclosure can perform an action of approaching or moving away from the intermediate plate 142. Correspondingly, the fixing plate 150 can also perform an action of approaching or moving away from the flipping plate 140.

[0089] Specifically, as shown in Figure 2 and Figure 3 , the lower surface of the fixing plate 150 in the present disclosure is connected to the intermediate slider 144. At the same time, a flipping suction cup 151 is arranged on the upper surface of the fixing plate 150, and the flipping suction cup 151 is used to adsorb the workpiece before changing the posture.

[0090] When the workpiece posture changing system in the present disclosure is in use, in the initial state, the flipping suction cup 151 is located above the fixing plate 150. At this time, a handling device such as a robotic arm transports the workpiece from the production line to the flipping device 100, and the workpiece will be adsorbed by the flipping suction cup 151 arranged on the fixing plate 150, so that the workpiece will not fall during the flipping process.

[0091] More preferably, a limiting device 152 is further arranged on the upper surface of the fixing plate 150. Specifically, the limiting device 152 has a through hole, and the flipping suction cup 151 is arranged in the through hole and the upper end of the flipping suction cup 151 is higher than the upper surface of the limiting device 152; when the flipping suction cup 151 in the present disclosure adsorbs the workpiece, its dimension in the vertical direction will be shortened. Thus, one surface of the workpiece in the present disclosure will be in pressure contact with the limiting device 152, so that the workpiece can be firmly adsorbed by the flipping suction cup 151 through the limiting device 152.

[0092] In addition, after the workpiece changes its posture, the flipping suction cup 151 is controlled to act to release the workpiece with the changed posture to the positioning device 200. Specifically, after the flipping driving device 130 acts, at this time the workpiece will be located below the fixing plate 150, and at this time, the negative pressure provided to the flipping suction cup 151 can be stopped. Thus, the workpiece can fall onto the positioning device 200 under the action of gravity.

[0093] That is to say, the positioning device 200 of the present disclosure is arranged below the flipping plate 140 or the fixing plate 150 of the flipping device 100. Before operating the flipping of the workpiece, the flipping plate 140 can be driven by the lifting driving device 110 to rise by a first preset distance to prevent the flipping plate 140 or the fixing plate 150 from colliding with the positioning device 200. After the workpiece is flipped, the flipping plate 140 is driven by the lifting driving device 110 to descend by a second preset distance, so that the fixing plate 150 is as close as possible to the positioning device 200 to prevent the workpiece from being damaged when it falls onto the positioning device 200.

[0094] In a specific embodiment, the number of the flipping suction cups 151 is set to 5. In the present disclosure, considering the requirements for flipping different workpieces, the number of the flipping suction cups 151 can also be set to other values.

[0095] In the present disclosure, a spring 153 is arranged between the middle plate 142 and the fixing plate 150, and the spring 153 is always in a pre-compressed state. That is to say, based on the middle plate 142, the spring 153 always exerts a thrust on the fixing plate 150 and makes the fixing plate 150 have a tendency to move away from the middle plate 142.

[0096] In a preferred embodiment, the number of the springs 153 is set to four, and these four springs 153 are respectively located at the four corners of the middle plate 142. More preferably, through holes are formed in the middle plate 142, threaded holes are formed on the lower surface of the fixing plate 150, screws pass through the through holes of the middle plate 142, are screwed into the threaded holes, and the springs 153 are sleeved outside the screws. Since the inner diameter of the through holes on the middle plate 142 is larger than the outer diameter of the screws, at this time, the screws will be able to slide in the through holes of the middle plate 142. Thus, the distance between the middle plate 142 and the fixing plate 150 can be changed. In addition, the diameter of the screw head of the screw is larger than the inner diameter of the through hole of the middle plate 142, so that the screw head of the screw can prevent the fixing plate 150 from detaching from the middle plate 142.

[0097] In a preferred embodiment, a first in-position sensor 154 can be arranged on the upper surface of the fixing plate 150, and the first in-position sensor 154 is used to detect the presence or absence of the workpiece. In a specific embodiment, the first in-position sensor 154 can be a distance sensor.

[0098] Figure 5 The structural schematic diagram of the positioning device of the workpiece attitude transformation system according to an embodiment of the present disclosure. Figure 6 The structural schematic diagram of the positioning device of the workpiece attitude transformation system from another angle according to an embodiment of the present disclosure.

[0099] The positioning device 200 is used to receive the workpiece after the attitude transformation and position the workpiece; thus, the positioning device 200 of the present disclosure can be stably held and accurately positioned. Correspondingly, when the workpiece is subsequently transported to the production line by a handling device such as a robotic arm, the workpiece also has a high positioning accuracy.

[0100] As Figure 5 and Figure 6 shown, the positioning device 200 of the present disclosure may include structures such as a base 210, a conveying drive device 220, a support plate 230, a positioning plate 240, a fixed suction cup 250, and a positioning assembly 260.

[0101] Specifically, the base 210 of the positioning device 200 can be fixed to components such as the ground or a workbench. A conveying drive device 220 is provided on the base 210; in a preferred embodiment, the conveying drive device 220 can be a rodless cylinder. Of course, those skilled in the art should know that the conveying drive device 220 can adopt a linear drive mechanism.

[0102] The support plate 230 is arranged on the conveying drive device 220. Thus, the conveying drive device 220 of the present disclosure can drive the support plate 230 to move in the horizontal direction. Specifically, since the conveying drive device 220 of the present disclosure is a rodless cylinder, correspondingly, the support plate 230 can be driven by the rodless cylinder to move along the guide shaft of the rodless cylinder.

[0103] In a preferred embodiment, the support plate 230 is generally arranged in a square shape, and support columns 270 are provided at the four corners of the support plate 230; in other words, four support columns 270 are provided in the present disclosure, and the lower ends of the support columns 270 are fixed to the upper surface of the support plate 230, and the lower ends of the support columns 270 are fixed to the lower surface of the positioning plate 240.

[0104] That is to say, the positioning plate 240 can be fixed to the support plate 230 through the support columns 270. Thus, the positioning plate 240 can move synchronously with the support plate 230.

[0105] The fixed suction cups 250 are all arranged on the positioning plate 240. Among them, the fixed suction cups 250 are arranged on the upper surface of the positioning plate 240. More preferably, a limiting component 280 is further arranged on the upper surface of the positioning plate 240. Specifically, the limiting component 280 has a through hole, and the fixed suction cup 250 is arranged in the through hole of the limiting component 280, and the upper end of the fixed suction cup 250 is higher than the upper surface of the limiting component 280. When the fixed suction cup 250 of the present disclosure adsorbs the workpiece, its dimension in the vertical direction will be shortened. Thus, one surface of the workpiece of the present disclosure will be in pressured contact with the limiting component 280, so that the workpiece can be firmly adsorbed by the fixed suction cup 250 through the limiting component 280.

[0106] Preferably, four fixed suction cups 250 of the present disclosure are arranged. In the present disclosure, considering the need to fix different workpieces, the number of the fixed suction cups 250 can also be set to other values.

[0107] The positioning components 260 are all arranged on the positioning plate 240. The positioning components 260 are used to position the workpiece in at least one direction, and the fixed suction cups 250 are used to adsorb the positioned workpiece and fix the position of the workpiece.

[0108] Specifically, in the present disclosure, the positioning components 260 are arranged to be movable relative to the positioning plate 240 to position the workpiece.

[0109] As Figure 5 and Figure 6 shown, the positioning component 260 includes: a positioning driving device 261 and a positioning member 262. Among them, the positioning driving device 261 is arranged on the positioning plate 240. Preferably, the positioning driving device 261 is fixed to the lower surface of the positioning plate 240, and the positioning driving device 261 can be realized by a linear driving mechanism such as a guiding cylinder.

[0110] The positioning member 262 is arranged on the positioning driving device 261, and the positioning driving device 261 can drive the positioning member 262 to perform an action of approaching or departing from the positioning plate 240. Among them, when the positioning member 262 approaches the positioning plate 240, the workpiece is positioned. Correspondingly, when the positioning member 262 departs from the positioning plate 240, the workpiece is released.

[0111] In a preferred embodiment, two positioning components 260 are arranged so that the workpiece is positioned in the first direction and the second direction, where the first direction and the second direction are perpendicular or substantially perpendicular.

[0112] Preferably, positioning posts 290 are arranged on the positioning plate 240, and the positioning posts 290 are used to cooperate with the positioning components 260 so that the workpiece is positioned.

[0113] In the present disclosure, the upper end of the positioning plate 240 is higher than the upper end of the fixed suction cup 250. Thus, the positioning plate 240 can contact the workpiece and drive the workpiece to move in the first direction or the second direction. At this time, the workpiece will be driven by the positioning plate 240 so that the workpiece contacts the positioning post 290. Thus, under the combined action of the positioning post 290 and the positioning plate 240, the positioning of the workpiece is achieved.

[0114] More preferably, the upper end of the positioning plate 240 includes two positioning portions, and through the contact of the workpiece with these two positioning portions, the workpiece is driven and positioned.

[0115] In a preferred embodiment, in the first direction, two positioning posts 290 are provided; at the same time, in the second direction, two positioning posts 290 are also provided. At this time, the combined positioning of the workpiece in the first direction and the second direction can be achieved.

[0116] In the present disclosure, when the workpiece is positioned, the conveying driving device 220 can be controlled to act. Correspondingly, the positioning plate 240 can be driven by the conveying driving device 220 to move from the first position to the second position; wherein, at the first position, the positioning device 200 is used to receive and position the workpiece after changing its posture; at the second position, the workpiece after changing its posture is taken away by a handling device such as a robotic arm.

[0117] In a preferred embodiment, a second in-position sensor can be provided on the upper surface of the positioning plate 240, and this second in-position sensor is used to detect the presence or absence of the workpiece. In a specific embodiment, this second in-position sensor can be a distance sensor.

[0118] When the workpiece posture transformation system of the present disclosure is in use, it can achieve the automatic flipping of workpieces such as mobile phones, and after flipping, it can be stably and highly accurately positioned, thereby improving the efficiency of mobile phone automatic production, reducing the labor intensity of workers, and improving the production efficiency of enterprises.

[0119] Specifically, when the workpiece posture transformation system of the present disclosure is in use, the workpiece can be conveyed from the production line to the flipping device 100 by a handling device such as a robotic arm and adsorbed by the flipping suction cup 151 of the flipping device 100, thereby achieving the fixation of the position of the workpiece. Then, the lifting driving device 110 is controlled to act, so that the workpiece rises to a preset position, and then the flipping driving device is controlled to act to achieve the flipping of the workpiece. At this time, the workpiece will be located below the fixing plate 150.

[0120] Next, the lifting driving device 110 is controlled to act, so that the workpiece descends. Thus, the workpiece can approach the positioning device; when the workpiece descends to near the positioning device, the lifting driving device 110 is controlled to stop descending, and then no negative pressure is provided to the flipping suction cup 151. At this time, the workpiece drops to the positioning device under the action of gravity.

[0121] The positioning component of the positioning device 200 acts to position the workpiece; when the workpiece is positioned, negative pressure is provided to the fixed suction cup so that the position of the workpiece is fixed. Then, the conveying drive device 220 is controlled to act so that the workpiece moves from the first position (flipping position) to the second position (loading position), and the workpiece is taken away by a handling device such as a robotic arm at the loading position; next, the conveying drive device 220 is controlled to act so that the positioning plate 240 is driven to the first position, realizing one working cycle.
