Detailed Implementation

[0050] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0051] like Figures 1-3 As shown, this utility model provides a laser engraving and alignment platform, comprising:

[0052] Support platform 1 for supporting solar cells;

[0053] The first propulsion component 2, the second propulsion component 4, the first positioning component 5, and the second positioning component 6 are sequentially arranged on the four outer sides of the bearing platform 1. The first propulsion component 2 corresponds to the first positioning component 5, and the second propulsion component 4 corresponds to the second positioning component 6.

[0054] Vision component 3 is disposed in the recessed cavity 13 on the outer side of the support platform 1;

[0055] Both the first propulsion assembly 2 and the second propulsion assembly 4 include:

[0056] The first fixed seat 71 is connected to the side of the bearing platform 1;

[0057] The first lifting cylinder 72 is connected to the first fixed base 71, and the output end of the first lifting cylinder 72 is vertically upward.

[0058] Servo motor 73 is connected to the output end of the first lifting cylinder 72, and the moving end of servo motor 73 is oriented toward the center of the support platform 1.

[0059] The first support plate 74 is connected to the moving end of the servo motor 73;

[0060] The propulsion column 75 is connected to the surface of the first bearing plate 74 and is close to the bearing platform 1.

[0061] In this embodiment, the battery cell is placed on the surface of the support platform 1. The first propulsion component 2 and the second propulsion component 4 are activated. The output end of the first lifting cylinder 72 extends, causing the propulsion column 75 to rise and align with the edge of the battery cell. The servo motor 73 is activated, causing the first support plate 74 to drive the propulsion column 75 closer to the support platform 1, so that the propulsion column 75 abuts against the edge of the battery cell. The propulsion column 75 pushes the battery cell to move on the surface of the support platform 1 until the battery cell simultaneously abuts against the first positioning component 5 and the second positioning component 6, thus completing the alignment of the battery cell. Using the servo motor 73 as the alignment power ensures smooth alignment, avoids rebound and wear, and ensures alignment accuracy. The alignment method of fixing on both sides and propulsing on both sides ensures uniform force on the battery cell and high alignment accuracy. The vision component 3 can capture the marked points on the battery cell to determine the accurate position of the battery cell, which helps to improve alignment accuracy.

[0062] like Figure 2 As shown, in an optional embodiment of the present invention, both the first propulsion assembly 2 and the second propulsion assembly 4 further include:

[0063] An extension plate 76 is formed on the edge of the first bearing plate 74 near the bearing platform 1, and the extension plate 76 extends along the edge of the bearing platform 1; multiple push columns 75 are evenly distributed on the upper surface of the extension plate 76.

[0064] In this embodiment, by uniformly arranging multiple push columns 75 on the surface of the extension plate 76, when the battery cell is being aligned, the multiple push columns 75 abut against the battery cell, so that the battery cell is subjected to uniform force, which helps to ensure the alignment accuracy.

[0065] In an optional embodiment of this utility model, both the first positioning component 5 and the second positioning component 6 include:

[0066] The second fixed seat is connected to the side of the bearing platform 1;

[0067] The second lifting cylinder is connected to the second fixed base, and the output end of the second lifting cylinder is vertically upward.

[0068] The second support plate is connected to the output end of the second lifting cylinder;

[0069] The positioning column is connected to the surface of the second bearing plate and is close to the bearing platform 1.

[0070] In this embodiment, during alignment, the output end of the second lifting cylinder extends, driving the positioning column to rise via the second support plate, so that the positioning column corresponds to the edge of the battery cell; the output end of the first lifting cylinder 72 extends, causing the push column 75 to rise and correspond to the edge of the battery cell; the servo motor 73 operates, causing the first support plate 74 to drive the push column 75 closer to the support platform 1, so that the push column 75 abuts against the edge of the battery cell, thereby pushing the battery cell to move on the surface of the support platform 1 through the push column 75 until the battery cell contacts the positioning column, thus completing the alignment of the battery cell.

[0071] like Figure 2 As shown, in an optional embodiment of this utility model, both the propulsion column 75 and the positioning column include:

[0072] Central column 81;

[0073] Wear-resistant sleeve 82 is rotatably mounted on the outside of central column 81.

[0074] In this embodiment, by rotating the wear-resistant sleeve 82 to be disposed outside the central column 81, when the wear-resistant sleeve 82 contacts the battery cell and when the battery cell moves relative to the wear-resistant sleeve 82, the friction between the wear-resistant sleeve 82 and the battery cell is rolling friction, which can reduce the wear on the battery cell and the wear-resistant sleeve 82 and help ensure the alignment accuracy.

[0075] like Figure 1 As shown, in an optional embodiment of the present invention, the first propulsion component 2 and the first positioning component 5 are respectively disposed on both sides of the bearing platform 1 along its length.

[0076] The second propulsion component 4 and the second positioning component 6 are respectively arranged on both sides of the bearing platform 1 in the width direction. There are multiple second propulsion components 4 and multiple second positioning components 6, and the multiple second propulsion components 4 and multiple second positioning components 6 are evenly distributed along the length direction of the bearing platform 1.

[0077] In this embodiment, the arrangement of the above structure enables the battery cells to be subjected to uniform force during alignment, thereby helping to improve alignment accuracy.

[0081] Fixing bracket 31 is connected to the inner wall of the recessed cavity 13;

[0082] Camera 36 is connected to the mounting bracket 31. Camera 36 is located inside the recessed cavity 13, and the lens of camera 36 is vertically upward.

[0083] In this embodiment, the camera 36 captures images of the marked points on the battery cell;

[0084] In this embodiment, camera 36 can be a small field-of-view camera with high single-pixel accuracy, which helps to improve the alignment accuracy.

[0085] like Figure 3 As shown, in an optional embodiment of the present invention, the vision component 3 further includes:

[0086] Guide rail 34 is connected to the fixed frame 31 and extends vertically;

[0087] Slider 35, camera 36 is connected to slider 35, slider 35 has a sliding cavity on its surface, and the sliding cavity is slidably connected to guide rail 34;

[0088] The positioning bolt is threaded on the outside of the slider 35, and the end of the positioning bolt extends into the sliding cavity and abuts against the guide rail 34.

[0089] In this embodiment, the slider 35 slides up and down relative to the guide rail 34 to adjust the height of the camera 36, ​​ensuring that the camera 36 can accurately capture the marked points on the battery cell. After the height adjustment of the camera 36 is completed, the positioning bolt is tightened to make the positioning bolt in close contact with the guide rail 34, thereby fixing the slider 35 and thus fixing the height of the camera 36.

[0090] like Figure 3 As shown, in an optional embodiment of the present invention, the vision component 3 further includes:

[0091] Top plate 32 is connected to the top of the fixed frame 31. The surface of top plate 32 is lower than the surface of the bearing platform 1. A clearance hole 33 is provided through the surface of top plate 32, and the clearance hole 33 corresponds to the lens of camera 36.

[0092] Upright plate 37, two upright plates 37 form a group, and the two groups of upright plates 37 are located on both sides of the clearance hole 33; an arc-shaped groove 38 is provided through the upper part of the upright plate 37;

[0093] There are two shielding plates 39, which are located between two corresponding upright plates 37. The shielding plates 39 have rotating shafts at both ends along their length, and the rotating shafts are slidably disposed inside the arc-shaped groove 38.

[0094] In this embodiment, when the device is in use, the shield 39 is rotated by the pivot and the arc groove 38, so that the shield 39 is away from the clearance hole 33 and the clearance hole 33 is fully exposed, which makes it easy for the camera 36 to accurately capture the marking points on the battery cell; when the device is not in use, the shield 39 is rotated by the pivot and the arc groove 38, so that the shield 39 covers the clearance hole 33, and the shield 39 blocks the clearance hole 33, thereby protecting the lens of the camera 36.

[0095] like Figure 1 As shown, in an optional embodiment of the present invention, the laser engraving and alignment platform further includes:

[0096] The flow guide cavity is located inside the bearing platform 1;

[0097] Air holes 11 are uniformly disposed throughout the surface of the bearing platform 1, and the air holes 11 are connected to the flow guide cavity.

[0098] The air extraction pipe 12 is located on the side of the support platform 1. The air extraction pipe 12 is connected to the guide cavity, and the outlet end of the air extraction pipe 12 is connected to the vacuum pump.

[0099] In this embodiment, after the battery cell is aligned, the vacuum pump operates, drawing air through the suction pipe 12, the guide cavity, and the air hole 11. The negative pressure is used to adsorb and fix the battery cell onto the surface of the support platform 1, thus fixing the battery cell. After the battery cell is fixed, the servo motor 73 operates, causing the first support plate 74 to drive the push column 75 away from the support platform 1. The output end of the first lifting cylinder 72 retracts, completing the reset of the push column 75. By first adsorbing and fixing the battery cell and then resetting the push column 75, the stability of the battery cell on the surface of the support platform 1 can be ensured, and the accuracy of the battery cell position can be guaranteed.

[0100] Cell alignment process:

[0101] The battery cell is placed on the surface of the support platform 1. The output end of the second lifting cylinder extends, driving the positioning column to rise through the second support plate, so that the positioning column corresponds to the edge of the battery cell. The output end of the first lifting cylinder 72 extends, causing the push column 75 to rise and correspond to the edge of the battery cell. The servo motor 73 works, causing the first support plate 74 to drive the push column 75 closer to the support platform 1, so that the push column 75 abuts against the edge of the battery cell. Thus, the push column 75 pushes the battery cell to move on the surface of the support platform 1 until the battery cell contacts the positioning column, completing the alignment of the battery cell. After alignment, the vacuum pump works, evacuating air through the suction pipe 12, the guide cavity, and the air hole 11. The negative pressure is used to adsorb and fix the battery cell on the surface of the support platform 1, achieving battery cell fixation. After the battery cell is fixed, the servo motor 73 works, causing the first support plate 74 to drive the push column 75 away from the support platform 1. The output end of the first lifting cylinder 72 retracts, completing the reset of the push column 75. The output end of the second lifting cylinder retracts, completing the reset of the positioning column.

[0102] The laser engraving and alignment platform provided in the above embodiments of this utility model uses a servo motor 73 as the alignment power, which ensures smooth alignment, avoids springback and wear, and ensures alignment accuracy. The alignment method of fixing on two sides and advancing on two sides ensures uniform force on the battery cells and high alignment accuracy.

[0103] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
