[0033] In all examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0034] Note that similar reference numerals and letters refer to like items in the following drawings, and thus, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0035] As shown in FIGS. 1-3, according to one aspect of the present disclosure, a positioning device is provided for battery production, comprising a carrying platform 1 and a positioning mechanism 2, wherein the carrying platform 1 is provided with a carrying station 11; the positioning mechanism 2 is arranged on the carrying platform 1, and the positioning mechanism 2 comprises a driving member 21 and a detecting member 22; the detecting member 22 is used to measure the size parameter of a flat material located at the carrying station 11, and the driving member 21 can make the flat material located at a set position of the carrying station 11 according to the size parameter.

[0036] Specifically, in the present embodiment, the positioning device can be used in the battery packaging process in battery production, i.e., by placing a flat material (such as a glass plate) at the carrying station 11 on the carrying platform 1, and by the positioning mechanism 2 for further position detection and adjustment of the flat material, so that it can be accurately located at the set position of the carrying station 11, facilitating the layout of battery pieces, welding strips and bus bars and other materials on the flat material, and realizing further lamination and welding to form a battery assembly.

[0037] In the above process, the positioning mechanism measures the size parameter of the flat material through the detecting member 22, and positions the flat material through the driving member 21 according to the size parameter, so that each flat material has accurate positioning, improving the reliability of the lamination and welding technology, and ensuring the product quality and yield in the battery production process. The detection form of the detecting member 22 can be contact detection or non-contact form, such as various distance sensors, and the driving member 21 can be a motor, a pneumatic cylinder or the like, which are not limited in the present disclosure.

[0038] Optionally, referring to FIG. 1, the carrying station 11 is the same as the shape of the flat material, and the positioning driving member 21 can make the flat material move to the center thereof coinciding with the center of the carrying station 11 according to the size parameter.

[0039] Specifically, in the present embodiment, the driving member 21 makes the flat material move to the center thereof coinciding with the center of the carrying station 11 according to the size parameter detected by the detecting member 22, realizing the uniformity of the positioning reference of each component (battery piece or welding strip, etc.) in the battery packaging process, avoiding the position accuracy error caused by the size error of the flat material formed during processing, and further improving the position accuracy.

[0040] The center of the flat material or the center of the carrying station 11 refers to the geometric center. In addition, the carrying station 11 has the same shape as the flat material, which is convenient for the position adjustment of the two, and the centers of the two are more easily coincided, which simplifies the convenience of the positioning mechanism 2 for the flat material adjustment. Further, when the size of the flat material changes, for example, the version changes, the position adjustment mode provided by the embodiment has better adaptability.

[0041] Optionally, referring to FIG. 1, the flat material is rectangular, the detection member 22 can measure the long side size parameter and the short side size parameter of the flat material, and the driving member 21 can move the flat material along the long side direction and / or the short side direction, so that the long side center of the flat material coincides with the long side center of the carrying station 11, and the short side center of the flat material coincides with the short side center of the carrying station 11, so as to realize the coincidence of the center of the flat material and the center of the carrying station 11.

[0042] Specifically, in actual application, the flat material is usually rectangular, which has a long side and a short side, and correspondingly, the carrying station 11 also has a long side and a short side. The positioning mechanism 2 in the embodiment can obtain the position center in the long side direction by measuring the size parameter of the long side of the flat material through the detection member 22, and can obtain the position center in the short side direction by measuring the size parameter of the short side of the flat material. The long side center and the short side center of the carrying station 11 are usually located at a certain position.

[0043] Further, after obtaining the long side center position and the short side center position of the flat material, the driving member 21 can move the flat material along the long side direction and / or the short side direction, so that the long side center coincides with the long side center of the carrying station 11, and the short side center of the flat material coincides with the short side center of the carrying station 11, so as to realize the coincidence of the center of the flat material and the center of the carrying station 11. The size measurement of the long side and the size measurement of the short side can be realized by various distance sensors and other detection members 22, such as infrared sensors, photoelectric sensors, etc., which reduces the measurement difficulty.

[0044] Optionally, referring to FIG. 1, a plurality of positioning mechanisms 2 are provided, at least one positioning mechanism 2 is provided at each side edge of the carrying station 11, and the number of the positioning mechanisms 2 on the opposite two side edges of the carrying station 11 is the same and is correspondingly arranged.

[0045] Specifically, in the embodiment, a plurality of positioning mechanisms 2 are arranged outside the carrying station 11, and at least one positioning mechanism 2 is arranged at each side edge in pairs, so that the opposite two positioning mechanisms 2 can obtain the distance between the opposite two side edges by detecting the positions of the corresponding side edges, and realize the purpose of measuring the size parameter of the flat material.

[0046] For example, in an embodiment, the flat material is rectangular, having long side and short side, and the carrying station 11 is also rectangular, having long side and short side. In actual application, by arranging two pairs of positioning mechanisms 2 on the two long sides of the carrying station 11 and arranging one pair of positioning mechanisms 2 on the two short sides, the distance between the two long sides, i.e. the short side size, is measured by the two pairs of positioning mechanisms 2 on the long sides, and the distance between the two short sides, i.e. the long side size, is measured by the one pair of positioning mechanisms 2 on the short sides.

[0047] Further, the position center in the long side direction and the short side direction can be calculated by the long side size and the short side size, and the long side center and the short side center of the flat material can be adjusted to coincide with the long side center and the short side center of the carrying station 11 by the positioning mechanisms 2, so as to realize the accurate positioning of the flat material. The measurement of the size can be realized by various distance sensors, the calculation of the size can be realized by the computing device or the electrical system, and the position adjustment of the flat material can be realized by the driving member 21, which can be designed according to actual needs, and the present disclosure does not limit this.

[0048] Alternatively, referring to FIGS. 1 and 2, it further comprises an electrical system (not shown in the figure), and the positioning mechanism 2 further comprises a guide structure; the driving member 21 is arranged on the carrying platform 1, and the detection member 22 and the guide structure are arranged on the output end of the driving member 21, and the detection member 22 and the driving member 21 are electrically connected with the electrical system; the driving member 21 can drive the detection member 22 to move towards the direction of approaching or moving away from the carrying station 11, so that the detection member 22 can detect the size parameter of the flat material located at the carrying station 11; the electrical system can make the driving member 21 drive the guide structure to guide the flat material to the set position according to the size parameter.

[0049] Specifically, in the present embodiment, the detection member 22 in the positioning mechanism 2 is used to detect the size parameter of the flat material and send it to the electrical system, and the electrical system can calculate the required adjustment position parameter of the flat material according to the size parameter, and the driving member 21 can drive the guide structure to move after obtaining the adjustment position parameter, so as to realize the position adjustment of the flat material. The position parameter can include the distance and direction that the flat material needs to move, and the driving member 21 can realize the movement of the detection member 22 by using a linear servo motor.

[0050] In the above embodiment, the driving member 21 can measure the size parameter of the flat material by driving the detecting member 22 to approach or move away from the flat material. The connection of the driving member 21 and the detecting member 22 with the electrical system facilitates the acquisition of the moving position parameter of the flat material and the sending of the size information of the flat material. In addition, the detecting member 22 and the guide structure can be fixed on the output end of the driving member 21 through the support structure, so that the measuring member and the guide structure can be located at a specific position of the carrying station 11, facilitating the size measurement and position adjustment of the flat material.

[0051] Optionally, referring to FIG. 3, the detecting member 22 comprises a fixed guide sleeve 221, a top sleeve 222 movably arranged at the end of the fixed guide sleeve 221, and a contact displacement sensor 223 arranged in the fixed guide sleeve 221 and connected with the top sleeve 222. When the driving member 21 drives the detecting member 22 to move towards the carrying station 11, the contact displacement sensor 223 can contact the flat material through the top sleeve 222.

[0052] Specifically, in the embodiment, when the detecting member 22 moves towards the flat material through the driving member 21, the contact displacement sensor 223 can contact the side edge of the flat material through the top sleeve 222, and the contact displacement sensor 223 can be driven to retract and slide in the fixed guide sleeve 221 by the top sleeve 222 after contacting the flat material. The electrical system calculates the distance between the contact points of the two positioning mechanisms 2 and the flat material according to the measured value and the moving value of the driving member 21, and realizes the acquisition of the size parameter of the entire flat material.

[0053] Further, the driving member 21 can drive the guide structure to adjust the flat material to the set position of the carrying station 11 according to the measured size information. For example, the long edge center or the short edge center of the flat material is adjusted to coincide with the long edge center or the short edge center of the carrying station 11. The contact displacement sensor 223 is a high-precision measuring device, which can meet the high-precision measurement requirement of microns, and further improves the positioning accuracy of the flat material.

[0054] Optionally, referring to FIGS. 1 and 2, the guide structure comprises two guide wheels, and the two guide wheels are located on the two sides of the detecting member 22, respectively. The driving member 21 can drive the two guide wheels to make the flat material located at the set position.

[0055] Specifically, in the embodiment, two guide wheels are located on both sides of the detection piece 22, so that in actual application, the two guide wheels can guide the flat material in two different directions, realize the position correction of the flat material, and further improve the positioning accuracy. Among them, the structure of the guide wheel is simple, which is convenient for the simplification of the structure. The detection piece 22 protrudes from the guide wheel in the measurement direction to avoid interference of the guide wheel with the detection of the detection piece 22.

[0056] Optionally, referring to FIG. 1, it further comprises a conveying mechanism 3 arranged on the bearing platform 1 for conveying the flat material to the bearing station 11.

[0057] Specifically, in the embodiment, the conveying mechanism 3 can convey the flat material from the last processing station or the stacking station to the bearing platform 1 and enable it to be located at the bearing station 11, realizing transportation and rough positioning of the flat material at the same time, so as to facilitate the subsequent positioning mechanism 2 to finely position it. Among them, the conveying mechanism 3 can adopt a conveying belt structure. As shown in FIG. 1, in order to improve the stability of the flat material conveying, two conveying belts can be arranged in the conveying direction to jointly support and convey the flat material.

[0058] Optionally, it further comprises a lifting mechanism (not shown in the figure), and the conveying mechanism 3 is arranged on the lifting mechanism, and the lifting mechanism can make the conveying mechanism 3 ascend or descend.

[0059] Specifically, in actual application, by arranging the conveying mechanism 3 on the lifting mechanism, the conveying mechanism 3 can ascend or descend relative to the bearing platform 1. During the conveying of the flat material, the flat material can be prevented from touching or interfering with other parts on the bearing platform 1, such as the positioning mechanism 2 arranged on the side of the bearing station 11, thereby improving the smoothness of the conveying. Further, when the flat material is conveyed to above the bearing station 11, the conveying structure is lowered to be flush with the position of the bearing station 11 by the descent of the lifting mechanism, realizing the placement of the flat material, and facilitating the further position fine adjustment of the flat material. Among them, the lifting mechanism can be realized by a linear air cylinder or an electric cylinder driving piece 21, and the present disclosure does not limit this.

[0060] Optionally, referring to FIG. 1, a plurality of suction mechanisms 4 are further arranged at the bearing station 11, and the suction mechanisms 4 are used for suction of the flat material.

[0061] Specifically, in the present embodiment, the adsorption mechanism 4 is arranged so that after the positioning mechanism 2 precisely positions the flat material, the flat material can be fixed at the set position of the carrying station 11, avoiding position deviation in the subsequent processing process, further improving the position precision of the flat material, and improving the production quality and yield of the product. The adsorption mechanism 4 can be realized by a suction cup or the like.

[0062] The above embodiments mainly describe the differences between the embodiments, and the different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory. For the sake of brevity, the details are not repeated here.

[0063] Although some specific embodiments of the present disclosure have been described in detail by examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present disclosure. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present disclosure.
