Description

Technical Field

[0001] The utility model belongs to the technical field of battery production equipment, in particular to a detection and correction device. Background Art

[0002] Among the many battery types, soft-pack batteries, with their advantages of light weight, high energy density, and flexible design, have gradually become an important energy storage solution in consumer electronics, new energy vehicles and other fields. In the production process of soft-pack batteries, after the battery cells are stacked, there is a subsequent process in which the battery cells are placed in pre-designed aluminum-plastic film pits that match their dimensions. The battery cells must be accurately placed in the aluminum-plastic film pits to ensure that the subsequent process steps proceed smoothly, which is a key link in meeting the quality standards of the final product. The precise placement of the battery cells is crucial for the subsequent lid closing and heat sealing process, because any slight deviation in the battery cell position may prevent the heat sealing equipment from performing the packaging operation effectively and accurately.

[0003] Existing technologies primarily rely on CCD (Charge Coupled Device) and other camera-based visual technologies, combined with advanced image processing algorithms, particularly grayscale analysis, to identify and determine the relative position between the battery cell and the aluminum-plastic film pit. These technologies capture and analyze images of the battery cell and the aluminum-plastic film pit, using grayscale differences to identify and locate the battery cell, thereby improving production automation. However, in practical applications, existing technologies have gradually revealed their limitations. A significant problem is that grayscale analysis primarily relies on differences in image brightness to distinguish between different objects. The surface material of the battery cell and the aluminum-plastic film often have a high degree of visual similarity in color. This difference can become extremely subtle or even imperceptible, especially under the influence of changing lighting conditions or differences in the glossiness of the material surface. This results in traditional grayscale-based image recognition algorithms misjudging or missing cell positions, making it difficult to achieve ideal recognition accuracy. This decline in recognition accuracy not only directly affects the precise positioning of the battery cells in the aluminum-plastic film pits, but also in the subsequent lid closing and heat sealing process, the battery cells with position deviation will lead to incomplete heat sealing or misalignment, which in turn will cause safety hazards such as internal short circuit and leakage in the battery, and may eventually cause the entire batch of batteries to be scrapped.

[0004] In view of the above technical limitations and potential production risks, a detection and correction device is proposed, which adopts a new recognition and detection technology to determine the relative position of the battery cell and the aluminum-plastic film pit, so as to overcome the shortcomings of traditional CCD visual recognition technology in complex environments, and can correct the battery cells with position deviation.

[0028] Any feature disclosed in this specification (including any appended claims and abstract), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0029] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0030] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of such features.

[0031] In the following embodiments, whether a battery cell is placed in an aluminum-plastic film pit is used as an example to illustrate. It should be understood that the design concept and principle of this solution are also applicable to whether other objects are placed in an aluminum-plastic film pit.

[0032] Example 1:

[0033] Figure 1The specific structure of the detection and correction device of the utility model is shown. The detection and correction device includes a bracket assembly 1, a detection mechanism 2 and a correction mechanism 3. The bracket assembly 1 is used to fix and support the entire structure. The detection mechanism 2 and the correction mechanism 3 are provided on the bracket assembly 1. When the detection mechanism 2 performs detection, the detection mechanism 2 corresponds to the position of the aluminum-plastic film pit 7 placed on the work station, such as Figure 4 As shown, the relative position of the battery cell 8 and the aluminum-plastic film pit 7 is detected. The correction mechanism 3 has a multi-directional translation adjustment mechanism. When the relative position of the battery cell 8 and the aluminum-plastic film pit 7 deviates, that is, when the battery cell 8 is not accurately placed in the aluminum-plastic film pit 7, the correction mechanism 3 will correct the position of the battery cell 8, and finally the battery cell 8 is accurately placed in the aluminum-plastic film pit 7, ensuring the smooth progress of subsequent processes.

[0034] Specifically, the bracket assembly 1 includes a vertically arranged first bracket 11 and a horizontally arranged base plate 13. A horizontal first slide rail 131 is provided on the base plate 13. A first slide groove is provided on the first bracket 11. The first slide rail 131 cooperates with the first slide groove to allow the first bracket 11 to slide on the base plate 13. A first driving mechanism 4 is fixed to the base plate 13. The first driving mechanism 4 is located on one side of the first bracket 11, and the output end is connected to the first bracket 11. The first driving mechanism 4 drives the first bracket 11 to slide back and forth on the base plate 13, which can realize the movement and positioning of the assembly in the front-to-back direction, thereby adjusting the position of the detection mechanism 2 on the first bracket 11 relative to the aluminum-plastic film pit 7, so that the detection mechanism 2 corresponds to the position of the aluminum-plastic film pit 7.

[0035] Specifically, the detection mechanism 2 includes four laser rangefinders 21. Four laser rangefinders 21 are provided on the first bracket 11. The four laser rangefinders 21 correspond to the four corners of the aluminum-plastic film pit 7 one by one, and the laser output end faces the aluminum-plastic film pit 7. Figure 5 As shown, the laser rangefinder 21 is used to measure the vertical distance between the laser rangefinder 21 and the corresponding angle of the aluminum-plastic film pit 7. The four laser rangefinders 21 can be located in the same plane and this plane is parallel to the horizontal plane. When the battery cell 8 has not been placed in the aluminum-plastic film pit 7, the four laser rangefinders 21 measure a distance each, and these four distances are the same. When the battery cell 8 is accurately placed in the aluminum-plastic film pit 7, as shown in FIG. Figure 7 As shown, the four laser rangefinders 21 measure four distances again, and the four distances are all smaller but still the same; when the battery cell 8 is not accurately placed in the aluminum-plastic film pit 7, as shown in FIG. Figure 6As shown, at this time, one or more of the four corners of the battery cell 8 are not placed in the aluminum-plastic film recess 7, and the distances measured by the corresponding laser rangefinder 21 remain unchanged. It should be understood that the four laser rangefinders 21 may not be located on the same plane. When the battery cell 8 is accurately placed in the aluminum-plastic film recess 7, the four distances measured by the four laser rangefinders 21 will decrease, and the amount of decrease is the same; when one or more of the four corners of the battery cell 8 are not placed in the aluminum-plastic film recess 7, the distances measured by the corresponding laser rangefinders 21 remain unchanged.

[0036] Specifically, two second brackets 14 are provided on the first bracket 11 and are parallel to each other. The distance between the two second brackets 14 can be adjusted. Figure 1 As shown, a through-hole can be provided in the second bracket 14. Also, a through-hole can be provided in the first bracket 11 at locations contacting the ends of the second bracket 14. Screws can be passed through the ends of the second bracket 14 and through corresponding locations on the lower first bracket 11 to secure the second bracket 14 to the first bracket 11. Two laser rangefinders 21 are provided on each second bracket 14, and the distance between the two laser rangefinders 21 can also be adjusted. Therefore, by adjusting the distance between the two second brackets 14 and the distance between the two laser rangefinders 21 located on the same second bracket 14, it is possible to detect whether different models of battery cells 8 are accurately placed in the aluminum-plastic film recesses 7.

[0037] Example 2:

[0038] Specifically, the first bracket 11 is provided with a vertical second slide rail 111 (at Figure 1 The bracket assembly 1 further includes a third bracket 12, which is provided with a second slide groove. The second slide rail 111 cooperates with the second slide groove so that the third bracket 12 can slide up and down along the first bracket 11, thereby enabling the movement and positioning of the assembly in the up and down directions. A second driving mechanism 5 is fixed to the first bracket 11, and the output end of the second driving mechanism 5 is connected to the third bracket 12, driving the third bracket 12 to slide along the first bracket 11. A correction mechanism 3 is provided on the third bracket 12, and the correction mechanism 3 is located at the rear and lower part of the detection mechanism 2, as shown in FIG. Figure 1 When the detection mechanism 2 detects that the battery cell 8 is not accurately placed in the aluminum-plastic film pit 7, the first driving mechanism 4 drives the first bracket 11 to slide on the bottom plate 13, so that the detection mechanism 2 is located above the aluminum-plastic film pit 7. The second driving mechanism 5 then drives the third bracket 12 to slide downward along the first bracket 11, so that the correction mechanism 3 approaches the battery cell 8 on the aluminum-plastic film pit 7 to correct the position of the battery cell 8.

[0039] Figure 2 Shows a lower side view of the correction mechanism 3; Figure 3The top side view of the correction mechanism 3 is shown. The correction mechanism 3 includes four correction components 31, which correspond to the four sides of the battery cell 8 and act on the four sides of the battery cell 8. Under the joint action of the four correction components 31, the position of the battery cell 8 is adjusted.

[0040] Specifically, the correction assembly 31 includes a correction plate 311 and a guide block 312. Two intersecting guide slots 121 are provided on the third bracket 12. The guide slots 121 can be two mutually perpendicular guide slots 121. Two slidable guide blocks 312 are provided in each guide slot 121. The bottom of the guide block 312 passes through the guide slot 121 and connects to the correction plate 311, driving the correction plate 311 to slide along the guide slot 121. The two guide blocks 312 sliding along the same guide slot 121 are parallel to each other and are also parallel to two opposite sides of the aluminum-plastic film pit 7. The guide blocks 312 correspond to the four sides of the aluminum-plastic film pit 7, and the guide blocks 312 push the battery cell 8, thereby adjusting the position of the battery cell 8. Four third drive mechanisms 6 are also provided on the third bracket 12. The output ends of the four third drive mechanisms 6 are respectively connected to the four guide blocks 312, driving the guide blocks 312 to slide along the guide slot 121. When the correcting mechanism 3 is not working, the two guide blocks 312 sliding along the same guide groove 121 are away from each other, and the shape and size of the four guide blocks 312 are larger than the size of the aluminum-plastic film pit 7. When it is detected that the battery core 8 is not accurately placed in the aluminum-plastic film pit 7, the first driving mechanism 4 drives the first bracket 11 to slide on the bottom plate 13, so that the intersection of the two guide grooves 121 is aligned with the center of the aluminum-plastic film pit 7, and the second driving mechanism 5 drives the third bracket 12 to slide downward along the first bracket 11, so that the detection mechanism 2 is close to the battery core 8 on the aluminum-plastic film pit 7. The third driving mechanism 6 drives the four guide blocks 312 to slide along their respective guide grooves 121 at the same time, moving two by two close to each other. After contacting the battery core 8, the battery core 8 is accurately entered into the aluminum-plastic film pit 7 under the joint push of the four guide blocks 312.

[0041] The following describes the working process of the detection and correction device in combination with the above-mentioned detection and correction device:

[0042] According to the size of the battery cell 8 or the aluminum-plastic film pit 7, adjust the distance between the two third brackets 12 and the distance between the two laser rangefinders 21 on the third bracket 12 so that the plane formed by the four laser rangefinders 21 is the same size as the aluminum-plastic film pit 7. After adjustment, fix the third bracket 12 and the laser rangefinder 21. After the battery core 8 is placed in the aluminum-plastic film pit 7, the second distance measurement is performed. According to the distances measured twice, it is judged whether the battery core 8 is accurately placed in the aluminum-plastic film pit 7. When it is detected that the battery core 8 is not accurately placed in the aluminum-plastic film pit 7, the first driving mechanism 4 drives the first bracket 11 to slide on the base plate 13 again, so that the intersection of the two guide grooves 121 is aligned with the center of the aluminum-plastic film pit 7. The second driving mechanism 5 drives the third bracket 12 to slide downward along the first bracket 11, so that the four guide blocks 312 are close to the battery core 8. The third driving mechanism 6 drives the four guide blocks 312 to slide along their respective guide grooves 121 at the same time, and moves close to each other in pairs. After contacting the battery core 8, the battery core 8 accurately enters the aluminum-plastic film pit 7 under the common push of the four guide blocks 312.
