Description

Technical Field

[0001] This utility model relates to the field of busbar adhesive removal equipment, and in particular to a busbar positioning gripper. Background Technology

[0002] Busbars extending from the surface of photovoltaic modules are used to connect photovoltaic modules and concentrate the electrical energy generated in the modules to ensure the normal operation of the entire photovoltaic system. During the production of photovoltaic modules, if the adhesive process is not standardized, such as uneven adhesive coating thickness, excessive adhesive viscosity, or excessive adhesive application, adhesive overflow can easily occur, and the overflowing adhesive can easily stick to the surface of the busbars.

[0003] To address the impact of adhesive residue on the surface of busbars on the conductivity of photovoltaic modules, the applicant proposed a busbar laser adhesive removal machine. The working principle involves setting up a laser emitter on the frame, which emits a laser beam from an angled upward to an angled downward, acting on the sidewalls of the busbars on the module surface to remove the adhesive.

[0004] However, in actual use, at least the following problems exist:

[0005] 1. The laser emitted by the laser emitter can easily damage other parts near the busbar;

[0006] 2. The laser emitter first performs laser adhesive removal on one group of busbars. Then, the horizontal moving component moves the laser emitter horizontally, so that the laser emitter moves directly above the next group of busbars to remove adhesive from the next group of busbars. During the horizontal movement of the laser emitter by the horizontal moving component, the entire frame will vibrate. When the laser emitter removes adhesive from the next group of busbars, the busbars may still be vibrating and have not stopped. This will cause the laser emitter's laser to not accurately act on the surface of the busbars, affecting the accuracy of laser adhesive removal.

[0007] Therefore, this application aims to provide a busbar positioning gripper to solve the technical problems in the prior art. Utility Model Content

[0008] To improve the accuracy of laser adhesive removal and mitigate the damage to other parts caused by the laser emitted by the laser emitter, this application provides a busbar positioning gripper.

[0009] The busbar positioning gripper provided in this application adopts the following technical solution:

[0010] A manifold positioning gripper includes a lifting cylinder, a connecting plate, a gripper cylinder, a first connecting block, and a second connecting block. One end of the connecting plate is connected to the lifting cylinder, and the other end of the connecting plate is connected to the gripper cylinder. The gripper cylinder is horizontally positioned and is used to drive the first connecting block and the second connecting block to move closer to each other and further away from each other. A first stop is provided on the side of the first connecting block closer to the second connecting block, and a second stop is provided on the side of the second connecting block closer to the first connecting block. A through hole for the manifold to pass through is provided between the first stop and the second stop.

[0011] Optionally, a first compression spring is connected between the first connecting block and the first stop block, and a second compression spring is connected between the second connecting block and the second stop block.

[0012] Optionally, it also includes a light-blocking strip, which is connected to the first connecting block or the second connecting block. The light-blocking strip is located between the two busbars and is used to block the gap between the two busbars.

[0013] Optionally, a plurality of first adjusting blocks are connected to the first stop block, and a plurality of second adjusting blocks are connected to the second stop block. A first stepped groove is formed on the side of the first adjusting block near the second adjusting block, and a second stepped groove is formed on the side of the second adjusting block near the first adjusting block. When the first adjusting block is close to the second adjusting block, the first stepped groove and the second stepped groove match. The light-blocking strip is located at the bottom of the first stop block and the second stop block.

[0014] Optionally, the surfaces of the first stop block and the second stop block are provided with a plurality of threaded holes, the first adjusting block and the second adjusting block are provided with a first through groove along the length direction, and the first adjusting block and the second adjusting block are provided with a first bolt.

[0015] Optionally, when the first block and the second block approach each other, at least a portion of the second block is located at the bottom of the first block, and both wide sides of the first block are provided with upright plates, with the light-blocking strip located above the first block.

[0016] Optionally, the first connecting block is connected to a third adjusting block, the third adjusting block having a threaded hole, the first stop block being fixedly connected to a first mounting plate, the first mounting plate having a second through groove along its length, a second bolt passing through the first mounting plate, the second bolt passing through the second through groove and being threadedly connected to the third adjusting block, the second connecting block being connected to a fourth adjusting block, the fourth adjusting block having a threaded hole, the second stop block being fixedly connected to a second mounting plate, the second mounting plate having a third through groove along its length, a third bolt passing through the second mounting plate, the third bolt passing through the third through groove and being threadedly connected to the fourth adjusting block.

[0017] Optionally, the light-blocking strip is provided with an adjustment hole, which is adapted to the second or third through slot.

[0018] In summary, this application includes at least the following beneficial effects:

[0019] 1. The gripper cylinder drives the first and second stops to move closer to each other, and the busbar passes through the space between the first and second stops. On the one hand, the blocking effect of the first and second stops makes it difficult for the laser emitted by the laser emitter to cause accidental damage to the surface of the component. On the other hand, the first and second stops abut against the two sides of the busbar respectively, which has a limiting effect on the busbar. During the operation of other mechanisms on the frame, the busbar is not easy to shake, which improves the accuracy of laser adhesive removal.

[0020] 2. The light-blocking strip is located between the two busbars to further block the area other than the busbars, and a vertical plate is set on the first stop block to improve the blocking effect of the positioning gripper; Attached Figure Description

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a full understanding of the present utility model. However, the present utility model 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 the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed below.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In utility models, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] During the laser removal process of the busbar by emitting a laser beam, the laser emitted by the laser emitter can easily damage other parts besides the busbar. Therefore, this application provides a busbar positioning gripper, referring to... Figure 1 A horizontally arranged transverse plate 9 is provided on the frame of the laser adhesive removal machine. Each pair of busbars forms a group. In this application, there are three busbar positioning claws. The three busbar positioning claws correspond to the three groups of busbars on the surface of the component. The busbar positioning claws are spaced apart along the length direction of the transverse plate 9, and the busbar positioning claws can slide along the length direction of the transverse plate 9.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. Example

[0035] Reference Figure 2 and Figure 3The manifold positioning gripper includes a lifting cylinder 1, a connecting plate 2, a gripper cylinder 3, a first connecting block 4, and a second connecting block 5. The lifting cylinder 1 is vertically positioned, and the connecting plate 2 is horizontally positioned. One end of the connecting plate 2 is connected to the lifting cylinder 1, and the other end of the connecting plate 2 is used to fix the gripper cylinder 3. The lifting cylinder 1 is used to drive the connecting plate 2 and the gripper cylinder 3 to move up and down in the vertical direction. The gripper cylinder 3 is horizontally positioned, and the first connecting block 4 and the second connecting block 5 are connected to the gripper cylinder 3. The gripper cylinder 3 is used to drive the first connecting block 4 and the second connecting block 5 to move up and down in the vertical direction. The second connecting blocks 5 are close to or far from each other. A first stop block 6 is provided on the side of the first connecting block 4 close to the second connecting block 5, and a second stop block 7 is provided on the side of the second connecting block 5 close to the first connecting block 4. There is a through hole between the first stop block 6 and the second stop block 7 for the busbar to pass through. A light-blocking strip 10 is provided between the two busbars. The light-blocking strip 10 is connected to the first connecting block 4 or the second connecting block 5. In this application, the light-blocking strip 10 is connected to the bottom of the second connecting block 5 and is used to block the gap between the two busbars.

[0036] Reference Figure 3 The diagram shows the state when the gripper cylinder 3 drives the first stop 6 and the second stop 7 to close. At this time, the busbar is located between the first stop 6 and the second stop 7. A first compression spring is connected between the first connecting block 4 and the first stop 6, and a second compression spring is connected between the second connecting block 5 and the second stop 7. With this arrangement, the first and second compression springs play a buffering role during the closing process of the cylinder gripper, avoiding accidental damage to the busbar caused by the excessive closing of the first stop 6 and the second stop 7.

[0037] The first stop block 6 is provided with a plurality of first adjustment blocks 11, and the second stop block 7 is provided with a plurality of second adjustment blocks 12. The first adjustment block 11 has a first stepped groove 13 on the side near the second adjustment block 12, and the second adjustment block 12 has a second stepped groove 14 on the side near the first adjustment block 11.

[0038] like Figure 3 As shown, this application has three first adjusting blocks 11 and three second adjusting blocks 12. The first adjusting blocks 11 are spaced apart along the length direction of the first stop block 6, and the second adjusting blocks 12 are spaced apart along the length direction of the second stop block 7. The outer sides of the two first adjusting blocks 11 and the two second adjusting blocks 12 located at the ends have vertical plates. Both the first stop block 6 and the second stop block 7 have threaded holes evenly distributed along their length. The first adjusting blocks 11 and 12 have first through slots 15 distributed along their length, which are adapted to the threaded holes. Each of the first adjusting blocks 11 and 12 is fitted with a first bolt 16. After the positions of the first adjusting blocks 11 and 12 are confirmed, the first bolts 16 sequentially pass through the first through slots 15 and are screwed into the threaded holes, thereby fixing the positions of the first adjusting blocks 11 and 12. Figure 3As shown, when the first stop block 6 and the first adjustment block 11 and the second adjustment block 12 approach each other, the first stepped groove 13 and the second stepped groove 14 match. At this time, the light-blocking strip 10 is located at the bottom of the first stop block 6 and the second stop block 7. By adjusting the position of the first adjustment block 11 and the second adjustment block 12, the first adjustment block 11 and the second adjustment block 12 are stacked, which further improves the shielding effect of the gripper on the laser. It should be noted that since the busbar needs to be smoothed and connected to the junction box afterward, whether the glue at the root of the busbar is completely removed will not have a significant impact. Therefore, the busbar glue removal machine focuses on removing the glue at the top of the busbar. Example

[0039] The difference between this embodiment and Embodiment 1 is that the structures of the first stop 6 and the second stop 7 are different from those in Embodiment 1. (Refer to...) Figure 4 and Figure 5 The upper surface of the second stop 7 is lower than the lower surface of the first stop 6. When the first stop 6 and the second stop 7 approach each other, at least a portion of the second stop 7 is located at the bottom of the first stop 6. A vertical plate 17 is provided on the outer wide edge of the first stop 6. In this embodiment, the light-blocking strip 10 is located above the first stop 6. The first connecting block 4 is connected to the third adjusting block 18. The third adjusting block 18 has a threaded hole. The first stop 6 is fixedly connected to the first mounting plate 19. The first mounting plate 19 has a second through groove 20 along its length. The first mounting plate 19 is located on top of the third adjusting block 18, so that the second through groove 20 communicates with the threaded hole. A second bolt 21 is passed through the first mounting plate 19. 1. After passing through the second through slot 20, it is threadedly connected to the third adjusting block 18. The light blocking strip 10 is bent and has an adjustment hole 8. The adjustment hole 8 of the light blocking strip 10 is adapted to the second through slot 20 or the third through slot 24. The second connecting block 5 is connected to the fourth adjusting block 22. The fourth adjusting block 22 has a threaded hole. The second stop block 7 is fixedly connected to the second mounting plate 23. The second mounting plate 23 has a third through slot 24 along its length. The second mounting plate 23 is located above the fourth adjusting block 22, so that the third through slot 24 communicates with the threaded hole. The second mounting plate 23 is provided with a third bolt 25. The third bolt 25 passes through the third through slot 24 and is threadedly connected to the fourth adjusting block 22.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
