DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0041] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0042] Figure 1 It is a structural schematic diagram of a battery string layout correction device provided in an embodiment of the present application, which integrates the functions of battery plate loading, conveying, detection, correction and unloading. Figure 2 yes Figure 1 A partial schematic diagram of loading and conveying a battery string includes a transmission frame 10 and a synchronous transmission assembly 20. The battery string 30 is transported to a specific shooting point below the gantry through the synchronous transmission assembly 20. Figure 3It is a side view of a battery string layout correction device, wherein a plurality of camera brackets 60 are slidably arranged on a gantry 50 at a shooting point, and a plurality of camera brackets 70 mounted on the camera brackets 60 are aimed at the battery string 30 below to shoot and detect the layout deviation state of the battery string. Figure 3 In the figure, three groups of camera brackets 60 are taken as an example for explanation, and the entire camera bracket 60 moves and captures images through the slide rails on the gantry 50.

[0043] Several groups of correction mechanisms 80 are also arranged on the gantry 50 at the shooting point. Two groups are illustrated in the figure of the present application. Each group of correction mechanisms 80 includes a lifting motor 81, a horizontal truss 82 arranged below the lifting motor 81, and several rows of suction pen assemblies 83 installed on the horizontal truss 82. The length of the suction pen assembly 83 is designed according to the length of the battery string group. When the camera detects the deviation, the suction pen assembly 83 will be controlled to suck the battery string 30, and the horizontal displacement will be adjusted through the horizontal posture adjustment mechanism.

[0044] Figure 4 The schematic diagram of the layout of the battery string group is shown, in which the red box area represents the schematic diagram of the gap between adjacent battery strings. This application mainly corrects the gap between battery strings when it is too large or does not meet the set requirements. Considering the accuracy of the correction problem, this application also sets several groups of guide components 40 in the synchronous transmission component 20 area of ​​the feeding part. Figure 5 Shows Figure 2 The schematic diagram of the structure of the guide component at A in the middle, the guide component is distributed at least in the four edge directions of the synchronous transmission component 20, and can be guided and preliminarily corrected during the transportation of the battery string. The structure specifically includes a guide rail 41, a sliding block 42, a roller 43 and a drive motor 44. The guide rail 41 is located below the synchronous transmission component 20, and the sliding block 42 is installed on the guide rail 41. A rubber roller 43 is installed on the sliding block 42, and the roller 43 is installed vertically at the same height as the battery string. The drive motor 44 is installed on the side of the sliding block 42, and is used to drive the sliding block 42 to move as a whole in the direction of the battery string. The rubber roller 43 can organize the battery string into a specific area to achieve preliminary correction.

[0045] A support frame is provided at the rear end of the synchronous transmission assembly 20, that is, the shooting point under the gantry. After the battery string is transported to this position as a whole, the camera bracket 60 can be controlled to move to a suitable angle on the track, and then the camera 70 installed on the frame can be used to shoot. If the gap between the battery strings detected in the captured image exceeds the threshold, the lifting motor 81 is started to absorb and correct the deviation. The correction accuracy of this step is higher.

[0046] Figure 6 It is a schematic diagram of the overall structure of the correction mechanism. Figure 7The pen suction assemblies 83 are arranged in a row, and the pen suction assemblies 83 in a row are hoisted below the horizontal truss 82 as a whole through the mounting plate 84, and are fixed on the frame through a plurality of mounting blocks 85.

[0047] Figure 8 8 is a schematic diagram of the structure of the suction pen assembly and the horizontal posture adjustment mechanism. The horizontal posture adjustment mechanism includes a plurality of cam mechanisms 86, and the cam mechanisms 86 are fixed on the mounting plate 84 and the suction pen assembly 83. Figure 8 Taking three groups of cam mechanisms 86 as an example, at least three groups of cam mechanisms 86 are evenly distributed on the suction pen assembly 83 below the mounting plate 84, and are distributed at intervals on the two end sides and the central area of ​​the mounting plate 84, respectively used to control the translation and swing of the suction pen assembly 83 in the upper horizontal direction. In a possible implementation, the cam mechanisms 86 on both sides control movement in a direction parallel to the horizontal truss 82, and the central cam mechanism 86 controls movement in a direction perpendicular to the horizontal truss 82.

[0048] Fig. 9 The schematic diagram of the structure of the cam mechanism is disclosed. Each cam mechanism 86 includes a cam seat 861, a cam 862 located in the cam seat 861, and a driving motor for controlling the movement of the cam 862. Figure 8 The three drive motors in the figure represent three groups of cam mechanisms. The drive motor is fixedly mounted on the mounting plate 84, and the cam seat 861 is fixedly mounted on the pen suction assembly 83 directly below the drive motor. The output shaft of the drive motor is connected to the cam 862 through the hole slot opened on the mounting plate 84. The drive motors at both sides control the cam 862 to move in the horizontal direction, and the drive motor at the center controls the cam 862 to move in the vertical direction.

[0049] It should be noted that the main purpose of the cam is to control the small swing of the suction pen assembly 83 to correct the deviation in a specific direction. The premise of this swing is the independent swing of the suction pen assembly 83, while the horizontal truss 82 and the mounting plate 84 are relatively immobile with the drive motor.

[0050] When it is necessary to control the battery string to perform horizontal displacement, such as lateral or longitudinal displacement, an additional adjustment mechanism is required. For this purpose, the present application fixes and hangs the mounting plate 84 on the horizontal truss 82 through a pair of mounting blocks 85 arranged at both ends, and an adjuster is installed on the bottom surface of the mounting block 85, and the horizontal displacement is achieved by the adjuster, which specifically includes a stacked lateral slide rail 842 and a longitudinal slide rail 843.

[0051] Fig.108 is a schematic diagram of the structure of the regulator, a hole slot 841 is provided on the mounting plate 84 below the mounting block 85, and a shaft 844 installed below the regulator passes through the hole slot 841 and is fixedly installed on the suction pen assembly 83 below. In this way, the horizontal displacement of the suction pen assembly 83 can be controlled by the regulator under the premise that the horizontal truss 82 and the mounting plate 84 are fixed.

[0052] In addition, considering the telescopic accuracy of the lifting motor 81 , a lifting mechanism 90 may be provided below the suction pen assembly 83 . Fig.11 It is a structural diagram of the lifting mechanism, which is located on the support frame at the rear end of the synchronous transmission component 20. When the battery string 30 is transported to the support frame and an offset is detected, the lifting mechanism 90 will lift the battery string 30 and then suck it up through the downward suction pen component 83.

[0053] Fig.12 It is a side view of the lifting mechanism, which includes a movable slide rail 91, a lifting plate 92 arranged on the movable slide rail 91, a plurality of supporting strips 93 installed on the lifting plate 92, and a lifting motor 95. The lifting plate 92 also includes a supporting body below, which spans the movable slide rail 91, and the two ends bear the functions of lifting and lowering, and the shape is equivalent to the hull structure. The lifting plate 92 is located below the strip 94, and the supporting strip 93 is fixedly installed on the lifting plate 92, and the lifting plates 92 are perpendicular to each other, and are spaced apart from the strips 94 arranged on the support frame, and are parallel to each other. The lifting motor 95 is connected to the lifting plate 92 in a transmission manner, and specifically controls the lifting and downward movement of the lifting plate 92 through the lifting shaft 96. Before lifting, the supporting strips 93 and the strips 94 are spaced apart, have the same height, and jointly carry the battery string. After lifting, the supporting strips 93 are lifted, and the battery string is lifted to a certain height, and then the suction pen assembly 83 sucks it and corrects it.

[0054] Fig.13 A flow chart of a battery string layout correction method provided in an embodiment of the present application is disclosed. The method is used in a battery string layout correction device, and the method comprises the following steps:

[0055] S1, transporting the battery string to the shooting point below the camera bracket 60 through the synchronous transmission component 20, and starting the camera 70 to shoot the layout state diagram of the battery string;

[0056] S2, extracting the contour structure of each battery string in the image and the edge spacing between the battery strings; when the edge spacing exceeds the set threshold, controlling the lifting motor 81 to move the battery string below the horizontal truss 82, and using the suction pen assembly 83 to suck up the battery string;

[0057] S3. Control the horizontal posture adjustment mechanism according to the edge spacing between the battery strings, adjust the edge spacing between the battery strings to a target range, and verify by photographing with the camera 70; when the verification is passed, lower the battery string to the support frame.

[0058] In some embodiments, controlling the horizontal posture adjustment mechanism according to the edge spacing between the battery strings to adjust the edge spacing between the battery strings to a target range includes:

[0059] Determine the horizontal adjustment distance of the regulator and the swing distance value of the cam mechanism 86 according to the spacing between each group of battery strings;

[0060] When the horizontal adjustment distance of the battery string needs to be changed, the horizontal and vertical distances of the battery string are controlled by the regulator installed on the bottom surface of the mounting block 85, wherein the horizontal slide rail 842 controls the horizontal movement of the entire suction pen assembly 83, and the vertical slide rail 843 controls the vertical movement of the entire suction pen assembly 83;

[0061] When the swing distance of the battery string needs to be changed, the center distance and the length of the swing arms at both ends are controlled respectively by at least three cam mechanisms 86 to adjust the swing angle of the battery string in real time.

[0062] In summary, this application sets a support frame at the shooting point below the gantry, uses a camera assembly to shoot the layout status of the battery string, and activates the suction pen assembly below to suck when the spacing exceeds the set threshold, and realizes directional angle swing adjustment through three sets of cam mechanisms. At the same time, an adjuster composed of stacked horizontal and longitudinal slide rails is also set under the horizontal truss to realize the overall horizontal displacement of the battery string.

[0063] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
