Abstract
Description
Technical Field
[0001] This application relates to the field of junction box disassembly technology, and in particular to a junction box disassembly tool. Background Technology
[0002] During the production of photovoltaic modules, faulty junction boxes may need to be disassembled, repaired, or replaced due to welding abnormalities or damage. When replacing a junction box, traditional methods are typically used for disassembly, usually employing homemade tools such as screwdrivers and utility knives. However, this method presents several problems: First, the adhesive around the junction box must be scraped clean and the connection between the adhesive and the junction box must be severed before disassembly. This cumbersome process requires repeated adjustments to the tool angle, resulting in low efficiency. Second, during disassembly, if the operator does not precisely control the force applied to the tool, the solder strip at the bottom of the junction box may be cut, compromising safety. Utility Model Content
[0003] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a junction box disassembly tool that can improve disassembly efficiency while ensuring operational safety.
[0004] A junction box disassembly tool, comprising:
[0005] Handles; and
[0006] A cutting component, connected to the handle, includes a cutting plate that extends into the gap between the junction box and the photovoltaic module and is used to cut the adhesive between the junction box and the photovoltaic module; the cutting plate is provided with a clearance portion for avoiding the solder strip connecting the junction box and the photovoltaic module.
[0007] In one embodiment, two clearance portions are provided, with each clearance portion corresponding to one of the two welding strips.
[0008] In one embodiment, the cutting plate has a positioning block at its front end, which is used to position and cooperate with the end face of the junction box.
[0009] In one embodiment, there are two positioning blocks, which are respectively disposed on opposite sides of the cutting plate, and are used to position and cooperate with the opposite two end faces of the junction box.
[0010] In one embodiment, at least one of the two positioning blocks facing each other has a guide portion; the guide portion is configured as an arc-shaped edge, or the guide portion is configured as a guide bevel, the guide bevel being set at an angle to the extending direction of the avoidance portion.
[0011] In one embodiment, the cutting plate has a cutting edge at its front end, which is located between the two positioning blocks.
[0012] In one embodiment, the distance between two opposite end faces of the junction box is set as a, and the distance between two opposite sides of the junction box is set as b; the spacing between the two positioning blocks is set as x, and the depth of the clearance portion along the insertion direction of the cutting plate is set as y; wherein, x≥a, y≥b.
[0013] In one embodiment, the cutting element further includes a connecting plate connected to the cutting plate and also connected to the handle, the handle and the cutting plate being spaced apart along the thickness direction of the cutting plate.
[0014] In one embodiment, the connecting plate includes a first split plate and a second split plate. The first split plate is set at an angle to the cutting plate and connected to it. The side of the first split plate facing away from the cutting plate is connected to the second split plate. The second split plate is connected to the handle.
[0015] The cutting component also includes a reinforcing member, and both the first split plate and the second split plate are connected to the reinforcing member.
[0016] In one embodiment, the connecting plate and the cutting plate are an integral structure; and / or, the cutting element is a metal element.
[0017] The aforementioned junction box removal tool allows for easy removal of the junction box. Simply insert the cutting plate of the cutting component into the gap between the junction box and the photovoltaic module from one side of the junction box, and push the cutting component to cut the adhesive between them. During this process, the cutting plate has a clearance section that avoids cutting the solder strip, effectively preventing it from being severed. Furthermore, after the cutting plate has completely passed through the junction box, the junction box can be pried open using the handle to remove it. Attached Figure Description

[0022] 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.
[0023] See Figures 1 to 3 , Figure 1 A structural diagram of a junction box disassembly tool according to an embodiment of this application is shown. Figure 2 It shows Figure 1 Enlarged structural diagram at point A. Figure 3 It shows Figure 1 The diagram shows the structure of the junction box disassembly tool during disassembly. One embodiment of this application provides a junction box disassembly tool including a handle 10 and a cutting component 20. The cutting component 20 is connected to the handle 10 and includes a cutting plate 21. The cutting plate 21 can extend into the gap between the junction box 30 and the photovoltaic module 40 and is used to cut the adhesive between the junction box 30 and the photovoltaic module 40. The cutting plate 21 has a clearance portion 211, which is used to avoid the solder strip 50 connecting the junction box 30 and the photovoltaic module 40.
[0024] When removing the junction box 30, the aforementioned junction box disassembly tool simply involves inserting the cutting plate 21 of the cutting member 20 into the gap between the junction box 30 and the photovoltaic module 40 from one side of the junction box 30, and pushing the cutting member 20 to cut the adhesive between the junction box 30 and the photovoltaic module 40. During the adhesive cutting process, the cutting plate 21 has a clearance part 211 that avoids the solder ribbon 50, effectively preventing the solder ribbon 50 from being cut by the cutting plate 21. Furthermore, after the cutting plate 21 has completely passed through the junction box 30, the junction box 30 can be removed by prying it with the handle 10.
[0025] Generally, there are two solder strips 50 between the junction box 30 and the photovoltaic module 40, spaced apart, and designated as the positive and negative solder strips respectively. Correspondingly, there are two clearance parts 211, each corresponding to one of the two solder strips 50. Thus, during the adhesive cutting process, each clearance part 211 can avoid its corresponding solder strip 50, effectively preventing accidental cutting of the solder strip 50 by the cutting plate 21 due to adhesive cutting.
[0026] The two clearance portions 211 enable the cutting plate 21 to have three cutting portions. The three cutting portions are arranged sequentially at intervals. The three cutting portions penetrate into the gap between the junction box 30 and the photovoltaic module 40, thereby cutting off most of the adhesive between the junction box 30 and the photovoltaic module 40, which facilitates the lifting and separation of the junction box 30 from the photovoltaic module 40.
[0027] Optionally, the clearance portion 211 may include, but is not limited to, clearance notches or clearance grooves, etc., which can be flexibly adjusted and set according to actual needs. The clearance portion 211 extends to the front edge of the cutting plate 21, thereby forming an opening at the front edge of the cutting plate 21.
[0028] It should be noted that the front edge of the cutting plate 21 refers to the side of the cutting plate 21 that faces the welding strip 50 when it is working, that is, the side away from the user.
[0029] Of course, as an optional solution, the avoidance part 211 can also be set to one, and one avoidance part 211 can simultaneously avoid two welding strips 50.
[0030] In related technologies, the disassembly tool is incompatible with the structure of the junction box 30, and slippage during disassembly can easily damage the box or clips. Therefore, for example, a positioning block 212 is provided at the front end of the cutting plate 21. The positioning block 212 is used to position and engage with the end face 31 of the junction box 30. Thus, before the cutting plate 21 is inserted into the gap between the junction box 30 and the photovoltaic module 40, it is positioned by the positioning block 212 against the end face 31 of the junction box 30, thereby ensuring that the clearance part 211 and the welding strip 50 are aligned along the insertion direction of the cutting plate 21, effectively preventing the welding strip 50 from being accidentally cut by the cutting plate 21.
[0031] Please see Figures 1 to 3For example, there are two positioning blocks 212, which are respectively disposed on opposite sides of the cutting plate 21. The two positioning blocks 212 are used to position and engage with the opposite end faces 31 of the junction box 30. Thus, the two positioning blocks 212 correspond to and abut against the opposite end faces 31 of the junction box 30, ensuring that the clearance part 211 and the welding strip 50 are aligned along the insertion direction of the cutting plate 21, making the disassembly of the junction box 30 more efficient and convenient. Furthermore, the cutting edge 213 at the front end of the cutting plate 21 is located between the two positioning blocks 212, making it safer during use and preventing accidents such as hand injuries from contact with the cutting edge 213, greatly improving safety.
[0032] When removing the junction box, the two positioning blocks 212 are positioned by abutting against the two opposite end faces 31 of the junction box 30. Then, the cutting plate 21 of the cutting piece 20 is inserted from one side of the junction box 30 along the surface of the photovoltaic module 40 into the gap between the junction box 30 and the photovoltaic module 40, and the adhesive is cut by the cutting plate 21. During the cutting of the adhesive, the cutting plate 21 has a relief part 211, which can avoid the solder strip 50, thus effectively preventing the solder strip 50 from being cut by the cutting plate 21. In addition, after the cutting plate 21 has completely passed through the junction box 30, the junction box 30 can be removed by prying it with the handle 10.
[0033] For example, at least one of the two positioning blocks 212 facing each other has a guide portion 2121. Optionally, the guide portion 2121 is a curved edge, or the guide portion 2121 is a guide bevel, which is set at an angle to the extending direction of the clearance portion 211. In this way, before the cutting piece 20 is inserted into the gap between the junction box 30 and the photovoltaic module 40, the two positioning blocks 212 abut against the two opposite end faces 31 of the junction box 30, and under the guidance of the guide portion 2121, the guiding and positioning operation between the cutting plate 21 and the junction box 30 can be quickly realized.
[0034] Specifically, each positioning block 212 is provided with a guide portion 2121, for example. The distance between the two guide portions 2121 increases along the insertion direction of the cutting member 20.
[0035] For example, the distance between two opposite end faces 31 of the junction box 30 is set as 'a', and the distance between two opposite sides of the junction box 30 is set as 'b'. The distance between the two positioning blocks 212 is set as 'x', and the depth of the clearance portion 211 along the insertion direction of the cutting plate 21 is set as 'y'. Optionally, x ≥ a, and x is specifically, for example, a, 1.05a, 1.1a, 1.15a, or 1.2a, etc. In this way, the two positioning blocks 212 can be fitted onto the outside of the junction box 30, and each positioning block 212 abuts against each end face 31 of the junction box 30. Optionally, y ≥ b, and y is specifically, for example, b, 1.05b, 1.1b, 1.15b, or 1.2b, etc. In this way, the cutting plate 21 can pierce from one side of the junction box 30 to the other side, which can completely cut the adhesive between the junction box 30 and the photovoltaic module 40, thereby facilitating the subsequent disassembly of the junction box 30.
[0036] For example, the cutting plate 21 has a cutting edge 213 at its front end. The cutting edge 213 is located between two positioning blocks 212. In this way, the two positioning blocks 212 act as a barrier, effectively preventing the hand from contacting the cutting edge 213 and causing cuts, thus improving safety performance.
[0037] Specifically, the cutting plate 21 has a cutting edge 213 in the entire area between the two positioning blocks 212 at its front end, which enables a larger area of the adhesive between the junction box 30 and the photovoltaic module 40 to be cut off by the cutting plate 21.
[0038] Please see Figures 1 to 3 For example, the cutting component 20 also includes a connecting plate 22. The connecting plate 22 is connected to the cutting plate 21 and also to the handle 10. The handle 10 and the cutting plate 21 are spaced apart along the thickness direction of the cutting plate 21. Thus, since the connecting plate 22 is provided on the handle 10 and the cutting plate 21, the handle 10 and the cutting plate 21 are not on the same plane, but are spaced apart, for example, along the thickness direction of the cutting plate 21. This makes it easier and less strenuous to disassemble the junction box 30 after the adhesive cutting is completed, as the junction box 30 can be pried open with a lever.
[0039] It should be noted that the "connecting plate 22" in this embodiment can be a part of the "cutting plate 21", that is, the "connecting plate 22" and the "other parts of the cutting plate 21" are integrally formed; or it can be an independent component that can be separated from the "other parts of the cutting plate 21", that is, the "connecting plate 22" can be manufactured independently and then combined with the "other parts of the cutting plate 21" to form a whole.
[0040] Please see Figures 1 to 3For example, the connecting plate 22 includes a first split plate 221 and a second split plate 222. The first split plate 221 is arranged at an angle to the cutting plate 21 and is connected to it. The side of the first split plate 221 facing away from the cutting plate 21 is connected to the second split plate 222, and the second split plate 222 is connected to the handle 10.
[0041] Please see Figure 3 Based on the aforementioned embodiments, the cutting component 20 further includes a reinforcing component 23. Both the first split plate 221 and the second split plate 222 are connected to the reinforcing component 23. Optionally, the reinforcing component 23 may include, but is not limited to, a reinforcing block, reinforcing rib, reinforcing strip, or reinforcing rod, etc., as long as it can stably combine the first split plate 221 and the second split plate 222 together.
[0042] For example, the cutting element 20 is a metal part. Alternatively, the cutting element 20 may be made of copper, stainless steel, iron, or aluminum, etc.
[0043] For example, the connecting plate 22 and the cutting plate 21 are an integrated structure.
[0044] In this embodiment, the connecting plate 22 and the cutting plate 21 are processed by sheet metal processing, or by other processes, such as die casting, forging or stamping.
[0045] It should be noted that the "reinforcing member 23" in this embodiment can be a part of the "cutting plate 21", that is, the "reinforcing member 23" is integrally formed with the "other parts of the cutting plate 21"; or it can be an independent component that can be separated from the "other parts of the cutting plate 21", that is, the "reinforcing member 23" can be manufactured independently and then combined with the "other parts of the cutting plate 21" to form a whole.
