The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing 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, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0050] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate 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 accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0051] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0052] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings.

[0054] Figure 1 It is a schematic structural diagram of a positioning device according to an embodiment of the present disclosure. Figure 2 It is a schematic structural diagram of a positioning device according to an embodiment of the present disclosure from another angle.

[0055] like Figure 1 and Figure 2 As shown, the positioning device of the present disclosure includes components such as a positioning platform 110 , a bracket portion 120 , and a positioning seat 130 .

[0056] The positioning platform 110 is formed as a plate-shaped component and is placed substantially horizontally, so that the positioning platform 110 can rotate along a vertical line in its central area. In other words, the first axis in the present disclosure is a vertical line or a substantially vertical line.

[0057] Figure 3It is a schematic structural diagram of a first driving device of a positioning device according to an embodiment of the present disclosure.

[0058] In this disclosure, Figure 3 As shown, the positioning platform 110 can be driven by the first driving device 101 to rotate along the first axis. Specifically, the positioning device of the present disclosure further includes a base plate 140, on which a shaft component 141 is disposed, and the positioning platform 110 is rotatably disposed on the shaft component 141. At this time, the shaft component 141 can be fixedly connected to the base plate 140.

[0059] In another embodiment, the shaft component 141 can be rotatably disposed on the bottom plate 140, and in this case, the positioning platform 110 and the shaft component 141 can be fixed. Of course, in this case, the positioning platform 110 can also be rotatably connected to the shaft component 141.

[0060] The first driving device 101 is arranged on the base plate 140, and a driving wheel 102 is arranged on the first driving device 101; a driven wheel 103 is rotatably arranged on the shaft component 141, that is, the driven wheel 103 can rotate relative to the shaft component 141, and the rotation axis 121 line of the driven wheel 103 is also the above-mentioned first axis line, the driving wheel 102 and the driven wheel 103 can be connected by a transmission member 104, and the positioning platform 110 is arranged on the driven wheel 103, so that when the first driving device 101 rotates, the positioning platform 110 can be driven to rotate.

[0061] In a preferred embodiment, the driving wheel 102 and the driven wheel 103 may be synchronous pulleys; the transmission member 104 may be a synchronous belt, so that the positioning platform 110 of the present disclosure has higher motion accuracy.

[0062] Figure 4 It is a partial structural schematic diagram of a positioning device according to an embodiment of the present disclosure. Figure 5 and Figure 6 yes Figure 4 Schematic diagram of the structure from other angles.

[0063] like Figures 4 to 6 As shown, the bracket part 120 is arranged on the positioning platform 110; in the present disclosure, the positioning platform 110 includes a length direction, and the bracket part 120 is arranged in two, and the two bracket parts 120 are respectively arranged at both ends of the length direction of the positioning platform 110.

[0064] The positioning seat 130 is rotatably disposed on the bracket portion 120, and the positioning seat 130 is driven to rotate along a second axis, the first axis being different from the second axis. Preferably, the first axis and the second axis are perpendicular or substantially perpendicular, that is, when the first axis is a vertical straight line, the second axis is a horizontal straight line or a substantially horizontal straight line.

[0065] More specifically, a rotating shaft 121 is disposed on the bracket portion 120 . For example, both ends of the rotating shaft 121 are rotatably disposed on the bracket portion 120 , so that the rotating shaft 121 can rotate around the axis of the rotating shaft 121 when driven.

[0066] Accordingly, the positioning seat 130 is fixed to the rotating shaft 121 , so that the positioning seat 130 can rotate relative to the positioning platform 110 .

[0067] In the positioning device disclosed in the present invention, the rotational movement around the first rotating axis is a rotational movement, and the rotational movement around the second rotating axis is a tumbling movement. At this time, when the positioning device is positioning workpieces such as batteries, a group of batteries are positioned in the positioning seat 130. The structure is stable, and during welding after rotation and flipping, there will be no contact jitter causing the welding steel sheet on the material to fall off.

[0068] Refer to Figures 4 to 6 A positioning block 122 is provided at one end of the rotating shaft 121, and at least one corner is formed on the positioning block 122; in a specific embodiment, the positioning block 122 is formed in a square shape with chamfers, that is, the rotating shaft 121 has four corners.

[0069] The bracket portion 120 is provided with a positioning member 123 , and the positioning member 123 is provided with a V-shaped groove, so that the positioning seat is positioned at a preset position through the cooperation between the corner portion and the V-shaped groove.

[0070] Preferably, a guide rail is provided on the bracket portion 120, and the positioning member 123 is slidably provided on the guide rail. More preferably, the bracket portion 120 can be driven by a cylinder to slide along the guide rail. The guide rail is vertically provided, and the positioning member 123 is located below the positioning block 122, so that the positioning member 123 can approach the positioning block 122 from below and cooperate with the positioning block 122.

[0071] Specifically, when the positioning device of the present disclosure is in use, after the positioning seat 130 is driven to rotate to a preset position, the positioning member 123 can be driven to move, and the positioning member 123 cooperates with the positioning block 122 to achieve high-precision positioning of the positioning seat 130 and prevent the positioning seat 130 from rotating. When the positioning seat 130 needs to rotate, the positioning member 123 can be controlled to descend, thereby allowing the positioning seat 130 to rotate. Further, after the positioning seat 130 rotates to a preset position, the positioning member 123 can be driven to rise again, thereby positioning the positioning seat 130 with high precision.

[0072] In the present disclosure, the bracket part 120 may be provided with a driving motor, which may be a servo motor, and the output shaft of the driving motor may be provided with a driving synchronous pulley; the rotating shaft 121 may be provided with a driven synchronous pulley, and the driving synchronous pulley and the driven synchronous pulley are connected by a synchronous belt. At the same time, the bracket part 120 may also be provided with a tensioning wheel, and the tensioning wheel is used to tension the synchronous belt.

[0074] The positioning device further includes: a lifting seat 150 and a pressing claw 160; the lifting seat 150 is slidably arranged on the positioning seat 130; the middle part of the pressing claw 160 is hinged to the positioning seat 130, and one end of the pressing claw 160 is hinged to the lifting seat 150, and through the lifting and lowering action of the lifting seat 150, the pressing claw 160 rotates and presses or loosens the workpiece to be positioned.

[0075] Specifically, a guide column is provided below the positioning seat 130, and a guide hole is opened on the lifting seat 150. A linear bearing is provided in the guide hole. At this time, the linear bearing is sleeved on the guide column, and enables the lifting seat 150 to move up and down under the guidance of the guide column.

[0076] The portion of the pressing claw 160 that contacts the workpiece may be provided with elastic materials such as rubber and silicone, thereby effectively preventing the positioning device of the present disclosure from causing scratches, indentations, and other damages to the product.

[0077] In the present disclosure, the positioning device further comprises: a lifting drive device 170, which is disposed on the positioning seat 130 and is used to drive the lifting seat 150 to lift and lower. The lifting drive device 170 may be a cylinder, thereby facilitating the positioning device of the present disclosure to clamp the workpiece when in use.

[0078] In one embodiment, at least part of the lifting seat 150 is located outside the positioning seat 130, and accordingly, the pressing claw 160 can be driven from the outside. In addition, the synchronous belt transmission parts of the present disclosure are all sealed with sheet metal covers to prevent pinching, making the structure safer and more reliable.

[0079] In addition, a baffle is also provided on the positioning seat 130 of the present disclosure, and the baffle is used to realize the horizontal positioning of the workpiece. Moreover, a position detection device is also provided on the bracket part 120, so that the position of the rotating shaft 121 can be determined by the position detection device. Specifically, the position detection device can be a beam switch. A disk is installed on the rotating shaft 121, and a through hole is opened on the disk. When the through hole is in the position between the beam switches, the beam switch is triggered to obtain the position of the rotating shaft 121. In a preferred embodiment, the beam switches are arranged in four groups, and the four groups of beam switches are evenly distributed along the circumference of the rotating shaft 121.

[0080] The positioning device disclosed in the present invention integrates the rotation action and the flipping action, thereby reducing the size of the device and reducing the transportation cost. Moreover, the assembly and debugging are relatively convenient, and the overall cost is also relatively low.
