Description

Technical Field

[0001] This application relates to the field of photovoltaic module processing technology, and in particular to a trimming mechanism, a secondary trimming device and a secondary trimming system. Background Technology

[0002] After the photovoltaic modules are manufactured, an edge trimming device is usually used to remove the excess adhesive from the four sides of the photovoltaic modules. Since the excess adhesive at the corners of each side is not easily removed by the edge trimming device, a secondary edge trimming device is usually required to remove the excess adhesive at the corners of the photovoltaic modules.

[0003] However, in the secondary edge trimming devices of related technologies, the edge trimming blade makes rigid contact with the side of the photovoltaic module. When the edge trimming blade approaches the side of the photovoltaic module, it is easy to scratch the side of the photovoltaic module. Especially when the edge trimming blade moves at a high speed towards the side of the photovoltaic module, it can easily lead to defects such as panel bursting, resulting in low product yield and high production costs. Utility Model Content

[0004] Therefore, it is necessary to provide an edge trimming mechanism, a secondary edge trimming device, and a secondary edge trimming system to address the defects in photovoltaic modules caused by existing technologies, such as side scratches and even panel bursting. This can improve product yield and reduce production costs.

[0005] In a first aspect, this application provides a trimming mechanism, comprising:

[0006] A fixed base is used to connect to a moving mechanism and can move towards or away from the side of the photovoltaic module under the movement of the moving mechanism;

[0007] A beveling cutter, the beveling cutter being mounted on the fixed base; and

[0008] An auxiliary positioning wheel is mounted on the fixed base. The auxiliary positioning wheel and the edge-cutting blade are both located on the same side of the fixed base. When the edge-cutting blade abuts against the side of the photovoltaic module, the wheel surface of the auxiliary positioning wheel simultaneously abuts against the side of the photovoltaic module.

[0009] In one embodiment, the cutting edge of the beveling knife is arranged parallel to the central axis of the auxiliary positioning wheel, and the cutting edge of the beveling knife protrudes from the wheel surface of the auxiliary positioning wheel along the moving direction of the beveling knife toward the side of the photovoltaic module; the protrusion height of the cutting edge of the beveling knife relative to the wheel surface of the auxiliary positioning wheel is set to S, 0.5mm≤S≤5mm.

[0010] In one embodiment, the auxiliary positioning wheel is rotatably disposed on the fixed base; and / or, the auxiliary positioning wheel is adjustablely disposed on the fixed base in a direction close to or far from the side of the photovoltaic module.

[0011] In one embodiment, the edge-trimming mechanism further includes a bracket, which is positionably mounted on the fixed base along a direction close to or away from the side of the photovoltaic module, and the auxiliary positioning wheel is rotatably disposed on the bracket.

[0012] In one embodiment, the edge-trimming mechanism further includes a connector, wherein one of the fixing base and the bracket is provided with a mounting hole and the other is provided with a waist-shaped hole, the length direction of the waist-shaped hole being the same as the direction of the fixing base near or away from the side of the photovoltaic module.

[0013] In one embodiment, the edge-trimming mechanism further includes a mounting base and an elastic element; the mounting base is disposed between the edge-trimming blade and the fixed base, the edge-trimming blade is mounted on the mounting base, the mounting base and the fixed base are rotatably connected, and the elastic element is connected between the mounting base and the fixed base.

[0014] In one embodiment, the edge-trimming mechanism further includes a baffle plate connected to the fixed seat or the mounting seat, the baffle plate being located outside the fixed seat and the mounting seat, and at least covering the gap between the fixed seat and the mounting seat.

[0015] Secondly, this application also provides a secondary edge trimming device, including the aforementioned edge trimming mechanism, and further including a moving mechanism, the moving mechanism being connected to the edge trimming mechanism, the moving mechanism being used to drive the edge trimming mechanism to move toward or away from the side of the photovoltaic module, and to drive the edge trimming mechanism to move along the side of the photovoltaic module.

[0016] In one embodiment, the moving mechanism includes a first moving component and a second moving component, the first moving component being connected to the second moving component, the first moving component being used to drive the fixed base to move along a first direction; the second moving component being used to drive the first moving component to move along a second direction, the second direction being set at an angle to the first direction.

[0017] Thirdly, this application also provides a secondary edge trimming system, which includes a plurality of the aforementioned secondary edge trimming devices, wherein the edge trimming blades of the plurality of secondary edge trimming devices are configured to correspond to a plurality of corners of the photovoltaic module.

[0018] In the aforementioned edge trimming mechanism, secondary edge trimming device, and secondary edge trimming system, when the fixed base moves towards the side of the photovoltaic module under the movement of the moving mechanism, the edge trimming blade and the wheel surface of the auxiliary positioning wheel will simultaneously abut against the side of the photovoltaic module. When the auxiliary positioning wheel abuts against the side of the photovoltaic module, it plays a positioning and buffering role for the photovoltaic module. This can prevent the edge trimming blade from having too great an impact force on the side of the photovoltaic module when it abuts against the side of the photovoltaic module alone, which would lead to scratches on the side of the photovoltaic module and defects such as panel bursting. It can also effectively improve the displacement defects of the photovoltaic module during the edge trimming process, thus improving the product yield and reducing production costs.

[0025] 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.

[0026] As described in the background art, the secondary edge trimming device in the related technology is prone to causing side scratches or even panel bursting of photovoltaic modules during use. The reason for this problem is that after the photovoltaic modules to be trimmed are transported to the edge trimming station, the position adjustment accuracy of the photovoltaic modules at the edge trimming station is not high enough, which can easily lead to offset defects. As a result, when the edge trimming knife moves at a high speed towards the side of the photovoltaic module during use, it can easily cause side scratches or even panel bursting of the photovoltaic modules.

[0027] Based on the above reasons, this application provides a trimming mechanism, a secondary trimming device, and a secondary trimming system, which can improve product yield and reduce production costs.

[0028] See Figure 1 This application provides a secondary edge trimming system, which includes multiple secondary edge trimming devices 10, each corresponding to a corner of a photovoltaic module 20. The correspondence between the corners of the photovoltaic module 20 and the secondary edge trimming devices 10 can be, for example, one-to-one or one-to-two.

[0029] In this embodiment, specifically, the photovoltaic module 20 has four corners. There are eight secondary edge trimming devices 10. Each corner corresponds to two secondary edge trimming devices 10. The relationship between each corner and its two corresponding secondary edge trimming devices 10 is that the two sides of the corner are arranged in a one-to-one correspondence with the two secondary edge trimming devices 10.

[0030] For example, the secondary edge trimming device 10 includes an edge trimming mechanism 11 and a moving mechanism 12. The moving mechanism 12 is connected to the edge trimming mechanism 11 and is used to drive the edge trimming mechanism 11 to move toward or away from the side of the photovoltaic module 20, i.e., as shown in the example. Figure 1 The double arrow X indicates the direction, thereby enabling the edge-trimming blade 112 of the edge-trimming mechanism 11 to abut against the side of the photovoltaic module 20 or retract to its initial position. The moving mechanism 12 is also used to drive the edge-trimming mechanism 11 to move along the side of the photovoltaic module 20, that is, as shown by the double arrow X in the diagram. Figure 1 The double arrow Y in the diagram indicates that the edge-cutting blade 112 moves along the side of the photovoltaic module 20 to remove excess adhesive from the corner.

[0031] The edge-trimming mechanism 11 includes a fixed base 111. The fixed base 111 is connected to the moving mechanism 12 and can move towards or away from the side of the photovoltaic module 20 under the movement of the moving mechanism 12. The direction in which the moving mechanism 12 causes the fixed base 111 to move towards or away from the side of the photovoltaic module 20 is defined as a first direction, i.e., as shown in the image. Figure 1 The double arrow X is shown in the diagram.

[0032] For example, the beveling mechanism 11 also includes a beveling cutter 112. The beveling cutter 112 is mounted on the fixed base 111.

[0033] For example, the edge-trimming mechanism 11 also includes an auxiliary positioning wheel 113. The auxiliary positioning wheel 113 is mounted on the fixed base 111, and both the auxiliary positioning wheel 113 and the edge-trimming blade 112 are located on the same side of the fixed base 111. When the edge-trimming blade 112 abuts against the side of the photovoltaic module 20, the wheel surface of the auxiliary positioning wheel 113 simultaneously abuts against the side of the photovoltaic module 20.

[0034] When processing the excess adhesive at the four corners of the photovoltaic module 20, the photovoltaic module 20 is moved to the edge trimming station. The edges of each corner of the photovoltaic module 20 are simultaneously abutted and positioned by the auxiliary positioning wheels 113 of the secondary edge trimming device 10. That is, the four corners of the photovoltaic module 20 are simultaneously abutted and positioned by eight auxiliary positioning wheels 113, achieving the alignment and fixation of the photovoltaic module 20 and effectively improving module displacement during the edge trimming process. Furthermore, each secondary edge trimming device 10 can reduce scratches and panel bursting defects during the removal of excess adhesive from the corner edges.

[0035] In the aforementioned edge trimming mechanism 11, secondary edge trimming device 10, and secondary edge trimming system, when the fixed base 111 moves towards the side of the photovoltaic module 20 under the movement of the moving mechanism 12, the wheel surfaces of the edge trimming blade 112 and the auxiliary positioning wheel 113 will simultaneously abut against the side of the photovoltaic module 20. When the auxiliary positioning wheel 113 abuts against the side of the photovoltaic module 20, it plays a positioning and buffering role for the photovoltaic module 20, which can avoid excessive impact force on the side of the photovoltaic module 20 when the edge trimming blade 112 abuts against the side of the photovoltaic module 20 alone, which would cause scratches on the side of the photovoltaic module 20 and defects such as panel bursting. It can also effectively improve the displacement defects of the photovoltaic module 20 during the edge trimming process, thus improving the product yield and reducing production costs.

[0036] Furthermore, after the chamfering blade 112 abuts against the side of the photovoltaic module 20, the moving mechanism 12 also drives the fixed base 111 to move along the extending direction of the side of the photovoltaic module 20; wherein, the moving direction in which the moving mechanism 12 causes the fixed base 111 to move along the extending direction of the side of the photovoltaic module 20 is set as a second direction, that is, as shown in the figure. Figure 1The double arrow y indicates the direction. When the edge-trimming blade 112 moves along the extension direction of the side of the photovoltaic module 20, it can remove the excess adhesive from the side of the photovoltaic module 20. When the edge-trimming blade 112 moves along the extension direction of the side of the photovoltaic module 20, the auxiliary positioning wheel 113 moves synchronously along the extension direction of the side of the photovoltaic module 20, so that the blade of the edge-trimming blade 112 remains parallel to the side of the photovoltaic module 20 it contacts. During the edge-trimming process, the side of the photovoltaic module 20 is subjected to more uniform force, which can avoid scratching the side of the photovoltaic module 20 and causing defects such as board bursting during the edge-trimming process, thereby improving the product yield and reducing production costs.

[0037] Please see Figures 1 to 3 For example, the moving mechanism 12 includes a first moving component 121 and a second moving component 122. The first moving component 121 is connected to the second moving component 122. The first moving component 121 is used to drive the fixed base 111 to move along a first direction. The second moving component 122 is used to drive the first moving component 121 to move along a second direction, which is set at an angle to the first direction. Thus, under the action of the moving mechanism 12, not only can the fixed base 111 be driven to move along the first direction, but it can also be driven to move along the second direction, thereby enabling the edge trimming blade 112 to move along the first direction, thereby moving closer to or away from the side of the photovoltaic module 20, and to move along the second direction, thereby removing the excess adhesive from the side of the photovoltaic module 20.

[0038] Specifically, the first moving component 121 and the second moving component 122 are each, but are not limited to, cylinders, motor screws, or hydraulic cylinders, etc.

[0039] Specifically, the first moving component 121 includes a power mechanism, a sliding seat 1211, a sliding table 1212, and a buffer 1213. The power mechanism is mounted on the sliding seat 1211, the sliding table 1212 is slidably disposed on the sliding seat 1211, and the fixed seat 111 is connected to the sliding table 1212. When the power mechanism pushes the sliding table 1212 to move, the sliding table 1212 slides along the sliding seat 1211 and moves the fixed seat 111 synchronously, thereby driving the edge-cutting blade 112 to move. The buffer 1213 is connected to the sliding seat 1211 and includes, but is not limited to, a hard limit screw. When the edge-cutting blade 112 moves in a direction away from the side of the photovoltaic module 20, the buffer 1213 can abut against the fixed seat 111, engaging with the fixed seat 111 to limit and ensure that the edge-cutting blade 112 does not jump during the edge-cutting process.

[0040] Please see Figure 1 and Figure 4For example, the cutting edge of the beveling blade 112 is arranged parallel to the central axis of the auxiliary positioning wheel 113, and the cutting edge of the beveling blade 112 protrudes relative to the wheel surface of the auxiliary positioning wheel 113 along the moving direction of the beveling blade 112 toward the side of the photovoltaic module 20. Thus, when the wheel surface of the auxiliary positioning wheel 113 abuts against the side of the photovoltaic module 20, the protruding cutting edge of the beveling blade 112 relative to the wheel surface of the auxiliary positioning wheel 113 ensures that excess adhesive on the side of the photovoltaic module 20 can be removed.

[0041] Please see Figure 4 Specifically, the protrusion height of the edge of the beveling blade 112 relative to the surface of the auxiliary positioning wheel 113 is set to S, where 0.5mm ≤ S ≤ 5mm. S includes, but is not limited to, 0.5mm, 1mm, 2mm, 3mm, 4mm, or 5mm. When S is less than 0.5mm, the protrusion height of the edge of the beveling blade 112 relative to the surface of the auxiliary positioning wheel 113 is small, resulting in a weaker effect on removing excess adhesive from the side of the photovoltaic module 20. When S is greater than 5mm, the protrusion height of the edge of the beveling blade 112 relative to the surface of the auxiliary positioning wheel 113 is large, which can easily lead to scratches on the side of the photovoltaic module 20 or even defects such as panel bursting.

[0042] Please see Figure 1 , Figure 4 and Figure 5 For example, the auxiliary positioning wheel 113 can be rotatably mounted on the fixed base 111 or fixedly mounted on the fixed base 111. When the auxiliary positioning wheel 113 is rotatably mounted on the fixed base 111, during the movement of the moving mechanism 12 driving the fixed base 111 along the extension direction of the side of the photovoltaic module 20, the auxiliary positioning wheel 113 can adaptably rotate, reducing the friction with the side of the photovoltaic module 20, thereby facilitating the removal of excess adhesive from the side of the photovoltaic module 20. Of course, when the auxiliary positioning wheel 113 is fixedly mounted on the fixed base 111, during the movement of the moving mechanism 12 driving the fixed base 111 along the extension direction of the side of the photovoltaic module 20, the auxiliary positioning wheel 113 will slide along the extension direction of the side of the photovoltaic module 20, also serving a positioning function.

[0043] As the time of the edge trimming mechanism 11 gradually increases, the blade of the edge trimming knife 112 gradually wears down, which causes the height S of the blade protruding from the wheel surface of the auxiliary positioning wheel 113 to gradually decrease, thereby affecting the removal effect of excess adhesive on the side of the photovoltaic module 20.

[0044] Please see Figure 1 . Figure 4 and Figure 5 For example, the auxiliary positioning wheel 113 is positioned along the direction of the side of the photovoltaic module 20 (e.g., ...). Figure 4The auxiliary positioning wheel 113 (as indicated by the double arrow X in the diagram) is adjustable in position on the mounting base 111. Thus, by adjusting the position of the auxiliary positioning wheel 113 in the direction close to or away from the side of the photovoltaic module 20, the size of S can be adjusted accordingly to a suitable size, improving the removal effect of excess adhesive from the side of the photovoltaic module 20 and extending the service life of the edge trimming blade 112, thereby reducing costs.

[0045] Specifically, when the edge of the edge-cutting blade 112 is worn, the position of the auxiliary positioning wheel 113 is adjusted appropriately in the direction away from the side of the photovoltaic module 20, so that S is adjusted to the preset range, thereby ensuring the removal effect of excess glue on the side of the photovoltaic module 20.

[0046] It should be noted that the auxiliary positioning wheel 113 can be directly mounted on the fixed base 111 or indirectly mounted on the fixed base 111. In this embodiment, in order to improve the stability of the auxiliary positioning wheel 113 on the fixed base 111 and to facilitate the adjustment of the position of the auxiliary positioning wheel 113, the edge-trimming mechanism 11 also includes a bracket 114. The bracket 114 is adjustablely mounted on the fixed base 111 in the direction of approaching or away from the side of the photovoltaic module 20. The auxiliary positioning wheel 113 is rotatably mounted on the bracket 114. That is, the auxiliary positioning wheel 113 is indirectly mounted on the fixed base 111. By adjusting the position of the bracket 114 in the direction of approaching or away from the side of the photovoltaic module 20, the position of the auxiliary positioning wheel 113 can be adjusted accordingly.

[0047] The auxiliary positioning wheel 113 has a rotating shaft at both ends, and the bracket 114 includes two support arms 1141. The support arms 1141 have shaft holes 1142, and each rotating shaft is rotatably disposed in each shaft hole 1142.

[0048] For example, the beveling mechanism 11 also includes a connector. The connector includes, but is not limited to, screws, pins, rivets, or snap-fit ​​components. One of the mounting base 111 and the bracket 114 is provided with a mounting hole 1111, and the other is provided with a slotted hole 1143. The length direction of the slotted hole 1143 is the same as the direction of the mounting base 111 near or away from the side of the photovoltaic module 20.

[0049] Specifically, each support arm 1141 is provided with a waist-shaped hole 1143. There are two mounting holes 1111, both of which are located on the fixing base 111. There are also two connecting pieces. Each mounting hole 1111 corresponds to each waist-shaped hole 1143, and each connecting piece corresponds to each waist-shaped hole 1143. The connecting pieces pass through the corresponding waist-shaped holes 1143 and mounting holes 1111 to connect and fix the support arm 1141 to the fixing base 111.

[0050] Please see Figure 4For example, the edge-trimming mechanism 11 also includes a mounting base 115 and an elastic element. The mounting base 115 is disposed between the edge-trimming cutter 112 and the fixed base 111. The edge-trimming cutter 112 is mounted on the mounting base 115, which supports and carries the edge-trimming cutter 112. The edge-trimming cutter 112 is, for example, detachably connected to the mounting base 115 and can be replaced as needed.

[0051] To facilitate the removal of excess adhesive from the sides of the photovoltaic module 20, the mounting base 115 has a mounting surface that forms an angle with the first direction. The angle between the mounting surface and the first direction includes, but is not limited to, 5°, 10°, 15°, 30°, 45°, 60°, 75°, or 85°. A beveling blade 112 is fitted against the mounting surface and fixed to the mounting base 115 by fasteners. The cutting edge of the beveling blade 112 protrudes beyond the area of ​​the mounting surface and forms an angle with the first direction. Thus, when the cutting edge of the beveling blade 112 comes into contact with the side of the photovoltaic module 20, it is angled relative to the side of the photovoltaic module 20, thereby facilitating the removal of excess adhesive from the side of the photovoltaic module 20.

[0052] The mounting base 115 and the fixed base 111 are rotatably connected, and an elastic element is connected between the mounting base 115 and the fixed base 111. When the blade of the edge-cutting knife 112 abuts against the side of the photovoltaic module 20, the elastic element acts as a buffer, enabling soft contact between the blade of the edge-cutting knife 112 and the side of the photovoltaic module 20, avoiding hard contact between the blade of the edge-cutting knife 112 and the side of the photovoltaic module 20, which would cause scratches and panel bursting defects.

[0053] The edge-trimming blade 112 scrapes away excess adhesive from the side of the photovoltaic module 20 at an angle relative to its side. One end of the edge-trimming blade 112 that is relatively far from the mounting base 111 is designated as the first end, and the other end opposite the first end is designated as the second end. The first end is relatively close to the side of the photovoltaic module 20, and the second end is relatively far from the side of the photovoltaic module 20. When the edge of the edge-trimming blade 112 is not in contact with the side of the photovoltaic module 20, a buffer gap 116, for example 0.5 mm to 5 mm, is provided between the portion of the mounting base 115 supporting the first end and the mounting base 111 under the elastic force of the elastic element. When the edge of the edge-trimming blade 112 contacts the side of the photovoltaic module 20, the portion of the mounting base 115 supporting the first end moves towards the mounting base 111, causing the elastic element to be compressed accordingly. Therefore, it can be seen that when the blade of the edge trimmer 112 comes into contact with the side of the photovoltaic module 20, it can adaptively float to achieve soft contact between the blade of the edge trimmer 112 and the side of the photovoltaic module 20, avoiding hard contact between the blade of the edge trimmer 112 and the side of the photovoltaic module 20, which would cause scratches and defects such as panel bursting. Moreover, the degree of floating of the blade of the edge trimmer 112 is, for example, between 0.5mm and 5mm, and the degree of floating is not too large, so as not to reduce the effect of removing excess glue from the side.

[0054] Please see Figure 4 and Figure 5 For example, the mounting base 115 has a first rotating part 1151, the fixed base 111 has a second rotating part, and the trimming mechanism 11 also includes a connecting shaft 117. The first rotating part 1151 and the second rotating part are rotatably connected via the connecting shaft 117. Specifically, the fixed base 111 has a positioning recess, and the first rotating part 1151 is rotatably disposed within the positioning recess. The positioning recess has a positioning function for the first rotating part 1151, which facilitates the quick and accurate assembly of the mounting base 115 and the fixed base 111 together.

[0055] Please see Figure 2 For example, the edge-trimming mechanism 11 also includes a baffle plate 118. The baffle plate 118 is connected to the fixed seat 111 or the mounting seat 115, and is located outside the fixed seat 111 and the mounting seat 115, at least blocking the gap between the fixed seat 111 and the mounting seat 115. In this way, the baffle plate 118 acts as a barrier, preventing tail material debris generated during the glue scraping process from falling into the gap between the fixed seat 111 and the mounting seat 115, thus preventing various defects such as the mounting seat 115 from getting stuck and unable to rotate.
