[0032] Techniques and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques and devices should be regarded as part of the specification.

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

[0034] It should be noted that: like reference numerals and letters denote like items in the following drawings; thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] As Figures 1 to 3As shown in the figure, according to one aspect of the present utility model, a positioning device is provided, which is applied to battery production and includes: a carrying platform 1 and a positioning mechanism 2. 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 includes a driving member 21 and a detecting member 22; the detecting member 22 is used to measure the dimensional parameters of the flat material located at the carrying station 11, and the driving member 21 can make the flat material located at the set position of the carrying station 11 according to the dimensional parameters.

[0036] Specifically, in this embodiment, the positioning device can be used in the battery encapsulation process in battery production. That is, by placing a flat material (such as a glass plate) at the carrying station 11 on the carrying platform 1, and further detecting and adjusting the position of the flat material through the positioning mechanism 2, so that it can be accurately located at the set position of the carrying station 11, which is convenient for typesetting battery wafers, solder tapes, busbars and other materials on the flat material, and further laminating and welding to form a battery module.

[0037] In the above process, the positioning mechanism measures the dimensional parameters of the flat material through the detecting member 22, and positions the flat material through the driving member 21 according to the dimensional parameters, so that each flat material has an accurate position, improving the reliability of the lamination welding technology and ensuring the product quality and product yield in the battery production process. Among them, the detection form of the detecting member 22 can be a contact detection or a non-contact form, such as using various distance sensors, etc., and the driving member 21 can adopt driving members such as motors and cylinders. The present utility model does not limit this.

[0038] Optionally, referring to Figure 1 , the shape of the carrying station 11 is the same as that of the flat material, and the positioning driving member 21 can make the flat material move so that its center coincides with the center of the carrying station 11 according to the dimensional parameters.

[0039] Specifically, in this embodiment, the driving member 21 makes the flat material move so that its center coincides with the center of the carrying station 11 according to the dimensional parameters detected by the detecting member 22, realizing the unity of the positioning reference of each component (such as battery wafers or solder tapes) in the battery encapsulation process, avoiding the position accuracy error caused by the dimensional error formed during the processing of the flat material, and further improving the position accuracy.

[0040] Among them, the center of the flat material or the center of the loading station 11 refers to the geometric center. Additionally, the shape of the loading station 11 being the same as that of the flat material is more convenient for the position adjustment of the two, making it easier for their centers to coincide, and simplifying the convenience of the positioning mechanism 2 for adjusting the flat material. Further, when the size of the flat material changes, such as the version changes, the position adjustment method provided in this embodiment has better adaptability.

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

[0042] Specifically, in practical applications, the flat material is usually rectangular, having a long side and a short side. Correspondingly, the loading station 11 also has a long side and a short side. The positioning mechanism 2 in this embodiment measures the dimension parameter of the long side of the flat material through the detection member 22, and can obtain the position center in its long side direction. By obtaining the dimension parameter of the short side of the flat material, the position center in its short side direction can be obtained. The long side center and the short side center of the loading station 11 are usually located at determined positions.

[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 its long side direction and / or short side direction, so that the long side center coincides with the long side center of the loading station 11, and the short side center of the flat material coincides with the short side center of the loading station 11, achieving the purpose of making the center of the flat material coincide with the center of the loading station 11. The measurement of the long side dimension and the short side dimension can be realized by various detection members 22 such as distance sensors, for example, infrared sensors, photoelectric sensors, etc., reducing the measurement difficulty.

[0044] Optionally, referring to Figure 1 , a plurality of the positioning mechanisms 2 are provided, at least one of the positioning mechanisms 2 is provided at each side of the loading station 11, and the number of the positioning mechanisms 2 on the opposite two sides of the loading station 11 is the same and they are arranged in one-to-one correspondence.

[0045] Specifically, in this embodiment, a plurality of positioning mechanisms 2 are arranged outside the loading station 11, and at least one positioning mechanism 2 is arranged in pairs at each side, so that two opposite positioning mechanisms 2 can obtain the distance between the opposite sides by detecting the positions of the corresponding sides, achieving the purpose of measuring the dimensional parameters of the flat material.

[0046] For example, in one embodiment, the flat material is rectangular, having a long side and a short side. Corresponding to the flat material, the loading station 11 is also rectangular, having a long side and a short side. In practical applications, two pairs of positioning mechanisms 2 are arranged opposite to each other on the two long sides of the loading station 11, and one pair of positioning mechanisms 2 is arranged opposite to each other on the two short sides, so that the distance between the two long sides, that is, the short side dimension, is measured by the two pairs of positioning mechanisms 2 on the long sides, and the distance between the two short sides, that is, the long side dimension, is measured by the one pair of positioning mechanisms 2 on the short sides.

[0047] Furthermore, the position centers in the long side direction and the short side direction can be calculated through the long side dimension and the short side dimension. By adjusting the long side center and the short side center of the flat material to coincide with the long side center and the short side center of the loading station 11 respectively through the positioning mechanism 2, the precise positioning of the flat material can be achieved. Among them, the measurement of the dimension can be realized by various distance sensors, the calculation of the dimension can be achieved by a computing device or an electrical system, and the position adjustment of the flat material can be realized by the driving member 21, which can be specifically designed according to actual needs, and the present utility model does not limit this.

[0048] Optionally, referring to Figure 1 and Figure 2 , it further includes an electrical system (not shown in the figure), and the positioning mechanism 2 further includes a guiding structure; the driving member 21 is arranged on the loading platform 1, the detecting member 22 and the guiding structure are both arranged on the output end of the driving member 21, and both the detecting member 22 and the driving member 21 are electrically connected to the electrical system; the driving member 21 can drive the detecting member 22 to move towards or away from the loading station 11, so that the detecting member 22 can detect the dimensional parameters of the flat material located at the loading station 11; the electrical system can, according to the dimensional parameters, make the driving member 21 drive the guiding structure to guide the flat material to the set position.

[0049] Specifically, in this embodiment, the detection member 22 in the positioning mechanism 2 is used to detect the dimensional parameters of the flat material and send them to the electrical system. The electrical system can calculate the position parameters that need to be adjusted for the flat material according to the dimensional parameters. After the driving member 21 obtains this adjusted position parameter, it can drive the guiding structure to move, so as to realize the position adjustment of the flat material. Among them, the position parameters can include the distance and direction that the flat material needs to move, etc. The driving member 21 can use a linear servo motor to move the detection member 22.

[0050] In the above embodiment, the driving member 21 can measure the dimensional parameters of the flat material by driving the detection member 22 to approach or move away from the flat material. The connection of the driving member 21 and the detection member 22 to the electrical system respectively facilitates obtaining the moving position parameters of the flat material and sending the dimensional information of the flat material. In addition, the detection member 22 and the guiding structure can be fixed on the output end of the driving member 21 through a supporting structure, so that the measuring member and the guiding structure can be located at specific positions of the loading station 11, facilitating the dimensional measurement and position adjustment of the flat material.

[0051] Optionally, referring to Figure 3 , the detection member 22 includes a fixed guide sleeve 221, a top sleeve 222 and a contact displacement sensor 223. The top sleeve 222 is movably arranged at the end of the fixed guide sleeve 221. The contact displacement sensor 223 is arranged inside the fixed guide sleeve 221 and is connected to the top sleeve 222. When the driving member 21 drives the detection member 22 to move towards the direction close to the loading station 11, the contact sensor can contact the flat material through the top sleeve 222.

[0052] Specifically, in this embodiment, when the detection member 22 moves towards the flat material through the driving member 21, the contact displacement sensor 223 can contact the side of the flat material through the top sleeve 222, and the contact displacement sensor 223 can be driven by the top sleeve 222 to contract and slide inside the fixed guide sleeve 221 after the top sleeve 222 contacts the flat material. The electrical system calculates the distance between the contact points of the two relative positioning mechanisms 2 and the flat material respectively according to its measured value and the moving value of the driving member 21, so as to obtain the dimensional parameters of the entire flat material.

[0053] Furthermore, the driving member 21 can drive the guiding structure to adjust the flat material to the set position of the loading station 11 according to the measured dimensional information. For example, adjust the long side center or short side center of the flat material to coincide with the long side center or short side center of the loading station 11. Among them, the contact displacement sensor 223 is a high-precision measuring device, which can meet the high-precision measurement requirements at the micron level and further improve the positioning accuracy of the flat material.

[0054] Optionally, referring to Figure 1 and Figure 2 , the guiding structure includes two guiding wheels, and the two guiding wheels are respectively located on both sides of the detecting member 22. The driving member 21 can drive the two guiding wheels to place the flat material at the set position.

[0055] Specifically, in this embodiment, the two guiding wheels are located on both sides of the detecting member 22, so that in practical applications, the two guiding wheels can guide the flat material in two different directions, realizing the position deviation correction of the flat material and further improving the positioning accuracy. Among them, the structure of the guiding wheel is simple, which is convenient for simplifying the structure. The detecting member 22 protrudes from the guiding wheel in the measuring direction to avoid the guiding wheel interfering with the detection of the detecting member 22.

[0056] Optionally, referring to Figure 1 , it further includes a conveying mechanism 3. The conveying mechanism 3 is arranged on the bearing platform 1 and is used for conveying the flat material to the bearing station 11.

[0057] Specifically, in this embodiment, the conveying mechanism 3 can convey the flat material from the previous processing station or the stacking station to the bearing platform 1 and make it located at the bearing station 11, realizing rough positioning of the flat material while transporting, so as to facilitate the subsequent positioning mechanism 2 to perform fine positioning on it. Among them, the conveying mechanism 3 can adopt structures such as conveyor belts. As Figure 1 shown, in order to improve the conveying smoothness of the flat material, two conveyor belts can be arranged in the conveying direction to jointly support and convey the flat material.

[0058] Optionally, it further includes a lifting mechanism (not shown in the figure). The conveying mechanism 3 is arranged on the lifting mechanism, and the lifting mechanism can make the conveying mechanism 3 rise or fall.

[0059] Specifically, in practical applications, by arranging the conveying mechanism 3 on the lifting mechanism, the conveying mechanism 3 can rise or fall relative to the bearing platform 1. During the process of conveying the flat material, it can avoid the flat material touching or interfering with other components on the bearing platform 1, such as the positioning mechanism 2 arranged on the side of the bearing station 11, improving the conveying smoothness. Further, when the flat material is conveyed above the bearing station 11, the conveying structure is lowered to be flush with the position of the bearing station 11 through the lowering of the lifting mechanism, realizing the placement of the flat material and facilitating the subsequent further fine adjustment of the position of the flat material. Among them, the lifting mechanism can be realized by driving members 21 such as linear cylinders or electric cylinders, and the present invention does not limit this.

[0060] Optionally, referring to Figure 1, a plurality of adsorption mechanisms 4 are further arranged at the loading station 11, and the adsorption mechanisms 4 are used for adsorbing the flat materials.

[0061] Specifically, in this embodiment, the arrangement of the adsorption mechanism 4 enables the flat material to be fixed at the set position of the loading station 11 after the positioning mechanism 2 adjusts the position of the flat material to achieve precise positioning, avoiding position deviation during subsequent processing, further improving the position accuracy of the flat material, and improving the production quality and yield of the product. Among them, the adsorption mechanism 4 can be realized by a suction cup or the like.

[0062] In the above embodiments, the differences between the embodiments are mainly described. As long as the different optimization features between the embodiments are not contradictory, they can be combined to form a more optimal embodiment. Considering the simplicity of the text, they will not be elaborated here.
