Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a silicone cutting device for photovoltaic modules. Background Technology

[0002] Junction boxes on photovoltaic modules are typically fixed to the backsheet of the module using silicone adhesive to ensure sealing and structural stability. However, this fixing method has the following problems in practical applications:

[0003] 1. Due to the high bonding strength of silicone and the various shapes of junction boxes, there is a lack of special disassembly tools when recycling or repairing components, resulting in low operating efficiency and even damage to the junction box or component structure due to violent disassembly.

[0004] 2. If chemical solvents (such as silicone solvents) are used for separation, they may corrode the junction box housing and internal electronic components, affecting their secondary use performance and increasing recycling costs.

[0005] 3. When disassembling with ordinary knives or hand tools, it is difficult for the operator to accurately control the force and angle, which can easily scratch the junction box shell or internal circuitry, causing irreversible physical damage and reducing the recycling rate.

[0006] Currently, no efficient and non-destructive method or specialized tool for disassembling junction boxes has been proposed, which restricts the economic and environmental benefits of photovoltaic module recycling and maintenance. Therefore, there is an urgent need to develop a dedicated disassembly solution for silicone-bonded photovoltaic junction boxes to achieve rapid and non-destructive separation, improve recycling efficiency, and reduce operation and maintenance costs. Utility Model Content

[0007] To address the technical problems in the background art, this utility model discloses a silicone cutting device for photovoltaic modules.

[0008] This utility model provides a silicone cutting device for photovoltaic modules, comprising:

[0009] A fixing cylinder is provided with a suction cup at its lower end for adsorbing the back of the photovoltaic module and connecting it to the junction box;

[0010] The cutting cylinder is inserted into the fixed cylinder;

[0011] Multiple cutters are horizontally positioned at the lower end of the cutting cylinder; the length of the cutters decreases in the direction of rotation of the cutting cylinder.

[0012] The junction box is positioned as follows: the area formed by the cutter rotating 360° covers the junction box, increasing with the length of the cutter; the area formed by the longest cutter rotating 360° covers the entire junction box.

[0013] Furthermore, when the suction cup is in the adsorption state, there is a gap between the fixing cylinder and the photovoltaic module.

[0014] Furthermore, a retaining ring extends radially outward from the upper end of the cutting cylinder; an adjusting bolt is threaded onto the retaining ring; the threaded end of the adjusting bolt abuts against the upper end of the retaining cylinder.

[0015] Furthermore, the lower end of the adjusting bolt is fitted with a ball bearing, which is in rolling connection with the upper end of the fixed cylinder.

[0016] Furthermore, the upper end of the fixed cylinder is provided with an annular arc groove; the ball bearings are engaged in the arc groove.

[0017] Furthermore, a locking nut is threaded onto the adjusting bolt; after the adjusting bolt is adjusted, the locking nut is close to the upper end of the fixed cylinder.

[0018] Furthermore, a groove is provided at the lower end of the cutting cylinder; the cutter is engaged in the groove.

[0019] Furthermore, a retaining block extends inward from the lower end of the cutting cylinder; a retaining groove is provided on the retaining block.

[0020] Furthermore, the extension direction of the slot coincides with the center of the cutting cylinder.

[0021] Furthermore, a horizontally arranged handle is provided at the upper end of the cutting cylinder; the handle coincides with the center of the upper end of the cutting cylinder.

[0022] The beneficial effects of this utility model are:

[0023] 1. The setting of the cutting cylinder plug-in fixed cylinder makes the position of the cutter more stable. Under the combined action of the weight of the cutting cylinder, the cutter will not float up and down. Not only is the cutting surface of the silicone smoother, but it is also less likely that the cutter will cut the junction box or photovoltaic module.

[0024] 2. The suction cup not only facilitates the assembly and disassembly of the fixed cylinder, but also provides stable support, preventing displacement of the fixed cylinder when the force and angle are out of control during manual operation.

[0025] 3. Through the rotary multi-length cutter design, the cutting cylinder gradually expands the cutting area during rotation, realizing the gradual separation of the silicone adhesive layer, avoiding damage to the junction box or component structure caused by violent disassembly, and significantly improving disassembly efficiency.

[0026] 4. It eliminates the risk of corrosion to the junction box housing and internal components without relying on chemical solvents, ensuring secondary use performance and reducing consumable costs; the tools are reusable, reducing the overall cost of photovoltaic module recycling and maintenance.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] like Figure 1-3 As shown, this utility model discloses a silicone cutting device for photovoltaic modules, including a vertically arranged, vertically connected fixed cylinder 1, and a cutting cylinder 4 inserted into the fixed cylinder 1, coaxially arranged and vertically connected.

[0037] The outer wall of the fixing cylinder 1 extends outward from near its lower end with four evenly distributed, horizontal fins 12. Mounting holes are provided on the fins 12, and the suction cup 2 is mounted on them. A screw is provided at the upper end of the suction cup 2, with two nuts threaded onto it. The screw passes through the mounting holes, and the nuts are located on the upper and lower sides of the fins 12. This allows for height adjustment of the suction cup 2 and also enables it to be locked in place. During installation, the fixing cylinder 1 is fitted onto the junction box 3, and the suction cup 2 is attached to the back of the photovoltaic module. This not only facilitates the installation and removal of the fixing cylinder 1 but also provides stable support, preventing displacement of the fixing cylinder 1 due to uncontrolled force or angle during manual operation. When the suction cup 2 is in the suction state, a gap exists between the fixing cylinder 1 and the photovoltaic module. This design prevents the fixing cylinder 1 from squeezing the photovoltaic module and causing it to break.

[0038] The lower end of the cutting cylinder 4 is provided with a plurality of evenly spaced, horizontally distributed locking blocks 43, which extend towards the center of the cutting cylinder 4. In this embodiment, there are three locking blocks 43. Figure 6 As shown, the lower side of the locking block 43 has a downward-facing, T-shaped slot 42, into which the cutter 5 is inserted. The slot 42 extends towards the center of the cutting cylinder 4, and the cutter 5 also extends towards the center of the cutting cylinder 4. This design offers the following advantages: 1. It facilitates the installation and removal of the cutter 5; 2. It provides high positional stability for the cutter 5; 3. During cutting, the groove wall of the slot 42 effectively supports the cutter 5, resulting in higher cutting efficiency; 4. During cutting, the force direction on the cutter 5 is perpendicular to the length direction of the slot 42, preventing displacement and ensuring stable cutting.

[0039] In this embodiment, as Figure 4 As shown, the length of the cutter 5 decreases sequentially along the cutting direction. The junction box 3 is positioned such that the area of ​​the junction box 3 covered by the region formed by the 360° rotation of the cutter 5 increases with the increase of the cutter 5 length; the area formed by the longest cutter 5 rotating 360° covers the entire junction box 3. This configuration has the following advantages: 1. The insertion of the cutting cylinder 4 into the fixing cylinder 1 makes the position of the cutter 5 more stable. Under the combined action of the gravity of the cutting cylinder 4, the cutter 5 will not float up and down, resulting in a smoother cutting surface for the silicone and reducing the likelihood of the cutter 5 cutting the junction box 3 or the photovoltaic module. 2. Through the rotating multi-length cutter 5 design, the cutting cylinder 4 gradually expands the cutting area during rotation, achieving gradual separation of the silicone adhesive layer, avoiding damage to the junction box 3 or module structure caused by violent disassembly, and significantly improving disassembly efficiency. 3. It eliminates the risk of corrosion to the junction box housing and internal components without relying on chemical solvents, ensuring secondary use performance and reducing consumable costs; the tools are reusable, reducing the overall cost of photovoltaic module recycling and maintenance.

[0040] The upper end of the cutting cylinder 4 extends radially outward with a retaining ring 41. Multiple evenly distributed adjusting bolts 6 are threaded onto the retaining ring 41, with the threaded ends of the adjusting bolts 6 abutting against the upper end of the retaining cylinder 1. This arrangement allows for adjustment of the height of the cutter 5 and maintains a stable height. Therefore, even if downward pressure is accidentally applied by hand while rotating the cutting cylinder 4, the pressure will only be transmitted to the retaining cylinder 1 and not to the cutter 5, preventing pressure from being generated between the cutter 5 and the photovoltaic module, thus protecting the photovoltaic module from damage.

[0041] A locking nut 8 is threaded onto the adjusting bolt 6; after the adjusting bolt 6 is adjusted, the locking nut 8 is close to the upper end of the fixed cylinder 1. This locks the adjusting bolt 6, preventing it from rotating under external force and causing deviation in the height of the cutter 5.

[0042] The lower end of the adjusting bolt 6 is also fitted with a ball bearing 7, which enables the cutting cylinder 4 to roll and connect with the fixed cylinder 1, thereby reducing friction and making the cutting cylinder 4 roll more easily.

[0043] like Figure 5 As shown, the upper end of the fixed cylinder 1 is also provided with an annular arc groove 11, and the ball 7 is engaged in the arc groove 11. This is used to limit the movement of the ball 7 and to guide the rotation of the cutting cylinder 4. This not only improves the rolling stability of the ball 7, but also improves the coaxiality between the cutting cylinder 4 and the fixed cylinder 1 when the cutting cylinder 4 rotates, making the cutting of the cutter 5 more stable.

[0044] A horizontally arranged handle 44 is provided at the upper end of the cutting cylinder 4; the center of the handle 44 coincides with the center of the upper end of the cutting cylinder 4. This arrangement not only maximizes the length of the handle 44, making it easier for workers to grip and apply force, but also ensures that the cutting cylinder 4 is subjected to uniform force, making it less likely for one end to tilt up and cause the cutter 5 to become misaligned.

[0045] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
