Description

Technical Field

[0001] This utility model relates to the field of battery cell welding, and in particular to a correction structure and anti-rollover device. Background Technology

[0002] To improve the light-receiving area of ​​solar cells and the efficiency of photovoltaic modules, existing technologies use triangular welding strips to weld the cells. However, in actual production, the triangular welding strips are soft and galvanized, making them prone to twisting and overturning without springing back. When the triangular welding strip twists and overturns, its bottom wall cannot fully adhere to the solar cell, affecting the efficiency of the photovoltaic module. Utility Model Content

[0003] Therefore, it is necessary to provide a corrective structure and anti-tipping device to address the problem in the existing technology where the bottom wall of the triangular welding strip cannot fully adhere to the solar cell after it twists and overturns, thus affecting the efficiency of the photovoltaic module.

[0004] The technical solution is as follows:

[0005] On the one hand, a correction structure is provided, including:

[0006] The supporting body is provided with a supporting part for supporting the triangular welding strip;

[0007] The first mounting body is provided with a guide portion extending along a first direction, the first direction being set at an angle to the horizontal plane;

[0008] A rotating shaft is mounted on the guide portion and moves in cooperation with the guide portion along the first direction;

[0009] A correction wheel is mounted on the rotating shaft and can rotate around the axis of the rotating shaft. The outer side wall of the correction wheel is provided with a correction groove extending circumferentially. The correction groove is located above the bearing part and cooperates with the bearing part to correct the triangular weld strip.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, the guide portion is configured as a waist-shaped groove, and the first mounting body includes a first mounting bracket and a second mounting bracket both mounted on the bearing body. The first mounting bracket and the second mounting bracket are respectively located on opposite sides of the bearing portion and are each provided with the waist-shaped groove. The two ends of the rotating shaft pass through the two waist-shaped grooves respectively.

[0012] In one embodiment, along the direction close to the bottom wall of the correction groove, the two inner sidewalls of the correction groove are inclined toward each other and are respectively used to limit the engagement with the two outer sidewalls of the triangular welding strip. The bottom wall of the correction groove is provided with a clearance groove for avoiding the top of the triangular welding strip.

[0013] In one embodiment, the top of the bearing portion is provided with a bearing surface, and the feeding side of the bearing portion is provided with a guide surface. The guide surface is connected to the bearing surface and is used to guide the triangular welding strip to the bearing surface.

[0014] In one embodiment, the number of the support parts is at least one, and each of the support parts is located on the top of the support body. The first mounting body, the rotating shaft and the correction wheel cooperate to form a correction module. The number of the correction modules is at least one, and each correction module is correspondingly arranged with each of the support parts.

[0015] In one embodiment, the various support portions are staggered along the axial direction of the rotation axis, and the projections of two adjacent support portions in the axial direction of the rotation axis do not overlap.

[0016] On the other hand, an anti-rollover device is provided, including a straightening structure and the correction structure, wherein the straightening structure is provided upstream and / or downstream of the correction structure, and the straightening structure is used to straighten the triangular weld strip.

[0017] In one embodiment, the correction structure includes a third mounting body and at least one rotating shaft, each of the rotating shafts being spaced apart along a direction close to or away from the correction structure, each of the rotating shafts being mounted on the third mounting body and being movable and engaged with the third mounting body along its own axial direction.

[0018] In one embodiment, the axis of each of the rotating shafts is located in a first plane, which is set at an angle to the horizontal plane.

[0019] In one embodiment, the angle between the first plane and the horizontal plane is less than 60°.

[0020] In the above embodiments, the correction structure and anti-tipping device, when in use, involve passing the triangular welding strip through the correction space formed by the inner wall of the support part and the correction groove, and then pulling the triangular welding strip. As the triangular welding strip moves forward, the correction wheel, driven by the triangular welding strip, can move along the first direction and rotate around the axis of rotation. The correction wheel applies pressure to the triangular welding strip based on its own weight, correcting the triangular welding strip as it twists and tilts through the correction groove. The bottom wall of the triangular welding strip remains facing the support part, ensuring complete contact between the triangular welding strip and the solar cell when pulled onto the cell, achieving the best reflective effect and thus ensuring the efficiency of the photovoltaic module. Furthermore, the correction wheel's ability to move along the first direction and rotate around the axis of rotation creates a floating effect, allowing for sliding contact between the correction wheel and the triangular welding strip without hard friction. This ensures smooth passage of the triangular welding strip without damaging the coating on the strip, improving the practicality and reliability of the correction structure.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a correction structure 100 is provided, including a support body 110, a first mounting body 120, a rotating shaft 130, and a correction wheel 140. The support body 110 has a support portion 111 for supporting the triangular welding strip 20. The first mounting body 120 has a guide portion 121 extending along a first direction, which is angled to the horizontal plane (e.g., ...). Figure 2 (Direction shown in B). The rotating shaft 130 is mounted on the guide portion 121 and moves in cooperation with the guide portion 121 in the first direction. The correcting wheel 140 is mounted on the rotating shaft 130 and can rotate about the axis of the rotating shaft 130. The outer side wall of the correcting wheel 140 is provided with a correcting groove 141 extending circumferentially. The correcting groove 141 is located above the bearing portion 111 and cooperates with the bearing portion 111 to correct the triangular weld strip 20.

[0031] In the above embodiment, the correction structure 100 is used by passing the triangular welding strip 20 through the correction space formed by the inner wall of the support part 111 and the correction groove 141, and then pulling the triangular welding strip 20. While the triangular welding strip 20 moves forward, the correction wheel 140 can move along the first direction and rotate around the axis of the rotation axis 130 under the drive of the triangular welding strip 20. The correction wheel 140 applies pressure to the triangular welding strip 20 by its own weight, so that the correction wheel 140 corrects the triangular welding strip 20 when the twisted and overturned triangular welding strip 20 passes through the correction groove 141. The bottom wall of the triangular welding strip 20 remains facing the support part 111, ensuring that the triangular welding strip 20 is completely attached to the solar cell 30 when it is pulled onto the solar cell 30, achieving the best reflective effect of the triangular welding strip 20, thereby ensuring the efficiency of the photovoltaic module. In addition, the correcting wheel 140 has the function of moving along the first direction and rotating around the axis of the rotation shaft 130, which can produce a floating effect, so that the correcting wheel 140 and the triangular welding strip 20 make sliding contact without hard friction contact. This ensures that the triangular welding strip 20 passes smoothly through the correcting wheel 140, while the correcting wheel 140 does not damage the coating on the triangular welding strip 20, thus improving the practicality and reliability of the correcting structure 100.

[0032] It should be noted that the triangular weld strip 20 refers to a weld strip with a triangular shape. For example, the triangular weld strip 20 can be set as a full triangular weld strip, or it can be set as an irregularly shaped weld strip with one end in a triangular shape and the other end in a flat or round shape.

[0033] In this specific embodiment, the first direction can be set to a vertical direction. In other embodiments, the first direction can also be set to an inclined direction.

[0034] In this embodiment, the support portion 111 is integrally formed with the support body 110. The first mounting body 120 can be installed on the support body 110 by screwing, snapping, plugging, or other means. The correction structure 100 also includes a bearing. The inner ring of the bearing is fixedly sleeved on the rotating shaft 130. The correction wheel 140 is fixedly sleeved on the outer ring of the bearing. The correction groove 141 is annular.

[0035] The guide part 121 can be configured as a waist-shaped hole, a slide, a guide rail or other guide structure.

[0036] like Figure 2 and Figure 3As shown, optionally, the guide portion 121 is configured as a waist-shaped groove. The first mounting body 120 includes a first mounting bracket 122 and a second mounting bracket 123, both mounted on the support body 110. The first mounting bracket 122 and the second mounting bracket 123 are located on opposite sides of the support portion 111, and both are provided with waist-shaped grooves. The two ends of the rotating shaft 130 pass through the two waist-shaped grooves respectively. In this way, the first mounting bracket 122 and the second mounting bracket 123 support and guide the two ends of the rotating shaft 130 respectively, ensuring that the rotating shaft 130 can drive the correcting wheel 140 to reciprocate along the first direction, thereby improving the reliability of the correcting structure 100.

[0037] Specifically, in this embodiment, both ends of the rotating shaft 130 are provided with limiting parts (such as limiting flanges or limiting rings), and the two limiting parts are respectively limited and cooperated with the side of the first mounting bracket 122 and the second mounting bracket 123 that are far away from each other.

[0038] like Figure 3 and Figure 4 As shown, optionally, along the direction close to the bottom wall of the correction groove 141, the two inner sidewalls of the correction groove 141 are inclined towards each other and are respectively used to limit the engagement with the two outer sidewalls of the triangular welding strip 20. The bottom wall of the correction groove 141 is provided with a clearance groove 142 for avoiding the top of the triangular welding strip 20. In this way, a gap is left between the top of the triangular welding strip 20 and the correction wheel 140. On the one hand, the contact area between the two is reduced, thereby reducing the risk of damage to the coating on the triangular welding strip 20. On the other hand, the clearance groove 142 allows triangular welding strips 20 with different top shapes to pass through, that is, the correction wheel 140 can accommodate triangular welding strips 20 with different top shapes, improving the practicality of the correction structure 100.

[0039] Specifically, in this embodiment, the size of the correction groove 141 is slightly larger than the size of the triangular welding strip 20. When the triangular welding strip 20 passes through the correction groove 141 and is not pulled, the bottom wall of the triangular welding strip 20 is in contact with the bearing part 111, and there is no interaction force between the triangular welding strip 20 and the correction wheel 140.

[0040] like Figure 2 and Figure 3 As shown, optionally, the top of the support portion 111 is provided with a support surface 1111. The feeding side of the support portion 111 is provided with a guide surface 1112. The guide surface 1112 is connected to the support surface 1111 and is used to guide the triangular welding strip 20 to the support surface 1111. In this way, the guide surface 1112 can smoothly guide the triangular welding strip 20 to the support surface 1111, avoiding the triangular welding strip 20 from scratching the support portion 111 during the movement to the support surface 1111, which would cause damage to the surface coating and improve the reliability of the correction structure 100.

[0041] In this specific embodiment, the guide surface 1112 is set as an arc-shaped surface and smoothly transitions to the bearing surface 1111.

[0042] The number of the bearing part 111, the first mounting body 120, the rotating shaft 130 and the correction wheel 140 can be flexibly adjusted according to the actual needs of use.

[0043] like Figure 2 As shown, in one embodiment, there is at least one support portion 111, and each support portion 111 is located on top of the support body 110. The first mounting body 120, the rotating shaft 130, and the correcting wheel 140 cooperate to form a correcting module. There is at least one correcting module, and each correcting module is correspondingly arranged with each support portion 111. In this way, one correcting module cooperates with one support portion 111 to correct one triangular welding strip 20. By setting multiple correcting modules and multiple support portions 111, the correcting structure 100 can simultaneously correct multiple triangular welding strips 20, improving the practicality of the correcting structure 100.

[0044] like Figure 2 As shown, optionally, each bearing portion 111 is oriented along the axial direction of the rotation axis 130 (e.g., ...). Figure 2 The bearings 111 are staggered in the direction shown in C, and the projections of two adjacent bearings 111 onto the axis of the rotation shaft 130 do not overlap. Thus, with two adjacent bearings 111 staggered along the axis of the rotation shaft 130, two adjacent correcting wheels 140 are also staggered accordingly. This reduces the distance between two adjacent correcting wheels 140 along the axis of the rotation shaft 130, making it suitable for situations with small spacing between multiple grid gates and improving the practicality of the correcting structure 100.

[0045] Specifically, in this embodiment, the axis of the rotating shaft 130 is arranged parallel to the horizontal plane. The various support components 111 are arranged in two staggered rows. On the same row, the second mounting bracket 123 in the correction module is integrally formed with the first mounting bracket 122 in the adjacent correction module. In other embodiments, the various support components 111 may also be arranged in three, four, or other staggered rows.

[0046] like Figure 1 As shown, in one embodiment, an anti-rollover device 10 is provided, including a correction structure 200 and a rectification structure 100 as described in any of the above embodiments. The correction structure 200 is provided upstream and / or downstream of the rectification structure 100, and the correction structure 200 is used to correct the triangular weld strip 20.

[0047] Specifically, in this embodiment, there is one corrective structure 200. The corrective structure 200 is located upstream of the corrective structure 100. Thus, after the triangular welding strip 20 is initially corrected by the corrective structure 200, it is then corrected by the corrective structure 100, ensuring that the bottom wall of the triangular welding strip 20 is conveyed onto the battery cell 30 and is completely in contact with the front side of the battery cell 30, thereby improving the reliability of the anti-rollover device 10.

[0048] In other embodiments, the number of corrective structures 200 is one. The corrective structure 200 may also be located downstream of the corrective structure 100.

[0049] The correction structure 200 can be configured as any structure in the prior art capable of correcting the triangular weld strip 20.

[0050] like Figure 1 As shown, the corrective structure 200 further includes a third mounting body 210 and at least one rotating shaft 220. Each rotating shaft 220 is spaced apart along a direction approaching or away from the corrective structure 100. Each rotating shaft 220 is mounted on the third mounting body 210 and moves in conjunction with the third mounting body 210 along its own axis. Thus, during the pulling of the triangular welding strip 20, while the triangular welding strip 20 is taut and drives the rotating shaft 220 to rotate around its own axis, the rotating shaft 220 also slightly wobbles along its own axis, thereby initially correcting the triangular welding strip 20. This corrects the triangular welding strip 20 where some of its apex contacts the rotating shaft 220 until its bottom wall contacts the rotating shaft 220, improving the reliability of the anti-rollover device 10.

[0051] The number and arrangement of the rotating shafts 220 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, both ends of the rotating shafts 220 are mounted on the third mounting body 210 via bearings. The axes of all rotating shafts 220 are located on the same straight line and are all parallel to the bearing surface 1111. The rotating shafts 220 are parallel to the axes of all rotating shafts 130.

[0052] like Figure 1 As shown, optionally, the axes of each rotating shaft 220 are located within a first plane. The first plane is set at an angle to the horizontal plane. Thus, setting each rotating shaft 220 along an oblique direction is more conducive to aligning the triangular welding strip 20 and improving the reliability of the anti-rollover device 10.

[0053] Specifically, in this embodiment, the correction structure 100 is located on one side of the uppermost pivot 220 on the third mounting body 210.

[0054] The angle between the first plane and the horizontal plane can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the angle between the first plane and the horizontal plane is less than 60°. For example, the angle between the first plane and the horizontal plane can be 30° or 45°.
