Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module processing technology, specifically a photovoltaic module edge trimming device. Background Technology

[0002] Photovoltaic modules, also known as solar panels or photovoltaic panels, are devices that directly convert sunlight into electrical energy. They are mainly composed of multiple solar cell units encapsulated in protective materials to enhance durability and environmental adaptability. After being laid out before lamination, photovoltaic modules must undergo a lamination process to tightly bond the cells, encapsulant film, and glass in a lamination cavity to form a photovoltaic module laminate. Due to factors such as misalignment of the encapsulant film within the cavity, the melting of the encapsulant film can cause residual adhesive to overflow from the glass edges. After lamination, an edge trimming machine is often used to trim the edges of the laminate. If the edges are not trimmed, it can easily lead to the laminate bursting during frame assembly. Residual burrs from the trimming process can cause the adhesive to curl and overflow from the frame after assembly, which not only affects the product's aesthetics but also seriously impacts the module's reliability and lifespan in adverse environments. To solve the problem of edge trimming in module laminates, improve trimming efficiency, and reduce the defect rate in module production, a photovoltaic module edge trimming device has been proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a photovoltaic module edge trimming device, which can trim the edges of photovoltaic modules during production using an edge trimming knife, and can rotate the edge trimming knife to switch to the unworn blade position using a ratchet mechanism, thereby reducing the frequency of edge trimming knife replacement.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] A photovoltaic module edge trimming device includes: a base, an edge trimming blade disposed on the top of the base, a pressure block disposed on the top of the edge trimming blade, four hexagonal flange nuts disposed on the top of the pressure block, and a ratchet mechanism disposed at the bottom of the base for adjusting the position of the edge trimming blade.

[0006] Optionally, the ratchet mechanism includes: a base shell, a ratchet, a locking lever, and a paddle. The base shell is mounted on the top of the base, and the ratchet is disposed inside the base shell. Two locking levers are disposed on one side of the inside of the base, and a paddle is disposed between the two locking levers. The paddle and the locking levers are rotatably connected to the base shell via rotating shafts. A lever is connected to the top of the paddle. A slot is formed on one side of the outer end of the base. A spring is disposed between the locking lever and the base shell. A connecting rod is installed between the ratchet and the base. The bottom of the ratchet is rotatably connected to the base shell via a rotating shaft. The ratchet mechanism composed of the base shell, ratchet, locking lever, and paddle is used to adjust the operating angle of the beveling tool.

[0007] Optionally, four threaded rods are installed on the top of the base, and four through holes are opened on the top of the edge-cutting blade and the pressure block. The top end of the threaded rod passes through the through hole and protrudes from the top of the pressure block. The outer wall of the hexagonal flange nut is threadedly connected to the inner wall of the threaded rod. An edge-cutting machine slide rail is provided at the bottom of the base, and the bottom of the base is connected to the sliding component in the edge-cutting machine slide rail. The threaded rods and the hexagonal flange nut are used for assembling and disassembling the edge-cutting blade.

[0008] The beneficial effects of this utility model are:

[0009] The advantage of this utility model is that the edge trimming knife can achieve efficient and precise edge trimming during the production process of photovoltaic modules. This not only effectively improves the efficiency and consistency of the edge trimming operation, but also significantly reduces the defect rate of modules caused by irregular edges, thereby improving the overall production yield and product quality.

[0010] Secondly, the beveling blade can be rotated via a ratchet mechanism. Since the beveling blade has a cross-shaped structure and can rotate, after the beveling blade wears out, it can be rotated to switch to the unworn blade position, reducing the frequency of beveling blade replacement and improving production efficiency in the photovoltaic module production process.

Detailed Implementation

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-6 As shown, a photovoltaic module edge trimming device includes: a base 1, an edge trimming blade 101 is provided on the top of the base 1, a pressure block 102 is provided on the top of the edge trimming blade 101, four hexagonal flange nuts 103 are provided on the top of the pressure block 102, and a ratchet mechanism is provided at the bottom of the base 1. The ratchet mechanism includes: a bottom shell 2, a ratchet 201, a locking rod 202, and a lever 203.

[0021] The base 1 has a bottom shell 2 mounted on top. A ratchet 201 is installed inside the bottom shell 2. Two locking rods 202 are located on one side of the base 1, with a lever 203 positioned between the two locking rods 202. When the position of the edge-trimming blade 101 needs to be adjusted, the lever 203 is rotated clockwise or counterclockwise. This rotation of the lever 203 causes the locking rods 202 to rotate and compress the spring 302. At this time, the base 1 can be rotated, causing the ratchet 201 to rotate, thus rotating the edge-trimming blade 101 to adjust its position. After the position of the edge-trimming blade 101 is adjusted, the spring force of the spring 302 pushes the locking rods 202, causing the locking rods 202 to... 2 One end engages with the ratchet teeth on the outside of the ratchet 201, thereby limiting the ratchet 201. This fixes the positions of the ratchet 201, the base 1, and the beveling blade 101. Since there are locking levers 202 on both sides of the ratchet 201, when the lever 203 rotates the left locking lever 202, the ratchet 201 can rotate clockwise. When the lever 203 rotates the right locking lever 202, the ratchet 201 can rotate counterclockwise. Since the beveling blade 101 has a cross structure and can rotate, after the beveling blade 101 is worn, it can be rotated to switch to the unworn blade position, reducing the frequency of beveling blade replacement and improving production efficiency in the photovoltaic module production process.

[0022] The paddle 203 and the lever 202 are rotatably connected to the base shell 2 via a rotating shaft. The top of the paddle 203 is connected to the lever 3. A slot 301 is provided on one side of the outer end of the base 1. A spring 302 is provided between the lever 202 and the base shell 2. Since the paddle 203 and the lever 202 are rotatably connected to the base shell 2 via a rotating shaft, the paddle 203 and the lever 202 can be rotated by the rotating shaft. The lever 3 makes it easy for the operator to rotate the paddle 203. The slot 301 is used to ensure that one end of the lever 3 passes through the base shell 2 and protrudes from the outside of the base shell 2.

[0023] A connecting rod 4 is installed between the ratchet 201 and the base 1. The bottom of the ratchet 201 is rotatably connected to the bottom shell 2 through a rotating shaft. When the operator rotates the base 1, the ratchet 201 can be rotated through the connecting rod 4. Since the ratchet 201 is rotatably connected to the bottom shell 2 through the rotating shaft, the bottom shell 2 can support the ratchet 201 without affecting its rotation.

[0024] The base 1 has four threaded rods 5 mounted on its top. The tops of the chamfering cutter 101 and the pressure block 102 each have four through holes 501. The tops of the threaded rods 5 protrude from the tops of the pressure block 102 through the through holes 501. The outer wall of the hexagonal flange nut 103 is threadedly connected to the inner wall of the threaded rods 5. When the chamfering cutter 101 needs to be replaced, the hexagonal flange nut 103 can be rotated off from the outside of the threaded rods 5. Then, the pressure block 102 and the chamfering cutter 101 are moved upwards sequentially until the pressure block 102 and the chamfering cutter 101 are completely replaced. The blades 101 slide out from the outside of the threaded rod 5, and then the unused edge-cutting blades 101 are placed outside the threaded rod 5 through the through hole 501 and fall on the top of the base 1. The pressure block 102 is placed on top of the edge-cutting blades 101 through the through hole 501 on the top of the pressure block 102. Finally, the four hexagonal flange nuts 103 are rotated to the outside of the threaded rod 5 until the bottom of the hexagonal flange nuts 103 is in contact with the pressure block 102, thereby fixing the edge-cutting blades 101 and the pressure block 102 on the top of the base 1.

[0025] The base 1 has a beveling machine slide rail 6 at its bottom, and the bottom of the base 1 is connected to the sliding component in the beveling machine slide rail 6. Since the bottom of the base 1 is connected to the sliding component in the beveling machine slide rail 6, the beveling machine slide rail 6 can drive the base 1 and the beveling cutter 101 to move laterally. Since the beveling machine slide rail 6 is a conventional means in the prior art, and this application has not improved the beveling machine slide rail 6, this application has not provided a detailed description of the usage method of the beveling machine slide rail 6.

[0026] Working principle:

[0027] When using this device, since the bottom of the base 1 is connected to the sliding component in the edge-trimming machine slide rail 6, the edge-trimming machine slide rail 6 can drive the base 1 and the edge-trimming blade 101 to move laterally. Therefore, the edge-trimming blade 101 can be used to trim the photovoltaic module. After prolonged use, the edge-trimming blade 101 will become dull. At this time, the lever 203 can be rotated clockwise or counterclockwise. When the lever 203 rotates, it will drive the locking lever 202 to rotate and compress the spring 302. At this time, the base 1 can be rotated to drive the ratchet 201 to rotate, so that the base 1... The movable beveling cutter 101 is rotated to adjust its position. After the position is adjusted, the spring force of the spring 302 pushes the locking lever 202, causing one end of the locking lever 202 to engage with the ratchet teeth on the outside of the ratchet 201, thus limiting the ratchet 201. Therefore, the positions of the ratchet 201, the base 1, and the beveling cutter 101 are fixed. Since locking levers 202 are provided on both sides of the ratchet 201, when the lever 203 rotates the left locking lever 202, the ratchet 201 can rotate clockwise. 3. When the right-hand lever 202 is rotated, the ratchet 201 can rotate counterclockwise. Since the edge-cutting blade 101 has a cross-shaped structure and can rotate, after the edge-cutting blade 101 is worn, it can be rotated to switch to the unworn blade position, reducing the frequency of edge-cutting blade replacement and improving production efficiency in the photovoltaic module production process. After multiple blade positions of the edge-cutting blade 101 become dull, the hexagonal flange nut 103 can be rotated off from the outside of the threaded rod 5. Then, the pressure block 102 and the edge-cutting blade 101 are moved upwards in sequence until the pressure block 102 is fully extended. 2. The edge-cutting blade 101 slides out from the outside of the threaded rod 5. Then, the unused edge-cutting blade 101 is placed outside the threaded rod 5 through the through hole 501 and falls on the top of the base 1. The pressure block 102 is placed on top of the edge-cutting blade 101 through the through hole 501 on the top of the pressure block 102. Finally, the four hexagonal flange nuts 103 are rotated to the outside of the threaded rod 5 until the bottom of the hexagonal flange nuts 103 is in contact with the pressure block 102, thereby fixing the edge-cutting blade 101 and the pressure block 102 on the top of the base 1. Therefore, the edge-cutting blade 101 is replaced.
