Description

Technical Field

[0001] This invention relates to the field of separation device technology, and in particular to a separation device capable of completely separating the glass of retired photovoltaic modules. Background Technology

[0002] Solar energy, as a new energy source, plays a significant role in alleviating the current global energy crisis and ecological environmental problems. The photovoltaic industry has subsequently experienced rapid development. However, with the retirement of the first batch of photovoltaic modules, the issue of recycling these retired modules has become increasingly prominent. A photovoltaic module consists of a junction box, aluminum alloy frame, glass, EVA film, crystalline silicon panel, and backsheet. Efficiently and energy-savingly separating the complete glass, crystalline silicon panel, and backsheet is a pressing problem that needs to be solved.

[0003] Currently, there are three main methods for separating glass, silicon wafers, and backsheets: physical crushing, chemical decomposition, and physical pyrolysis. Physical crushing is cumbersome, time-consuming, labor-intensive, and has low recycling efficiency due to the good flexibility of the EVA film, resulting in high costs and significantly reduced glass recycling value. Chemical decomposition, on the other hand, has low dissolution efficiency because the EVA film is only soluble in a few organic and inorganic acid solvents such as trichloroethylene, thus reducing separation efficiency and producing harmful substances like toluene and acetaldehyde, which can easily cause secondary pollution. Finally, physical pyrolysis currently mainly involves cutting the adhesive layer with blades and wire ropes. However, the EVA film is very thin, making it difficult for blades and wire ropes to cut into it accurately, easily causing scratches and damage to the recycled items, requiring further sorting, increasing production steps, and reducing recycling efficiency. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the existing physical pyrolysis method mainly uses blades and steel wire ropes to cut the adhesive layer. However, the thickness of the EVA film is very small, and the blades and steel wire ropes cannot cut into the EVA film completely and correctly, which can easily lead to scratches and damage to the recycled items. This requires re-sorting, increases the production process, and reduces the recycling efficiency. The present invention provides a separation device that can completely separate the glass of retired photovoltaic modules.

[0005] The technical solution adopted by this invention to solve its technical problem is: a separation device for completely separating the glass of a decommissioned photovoltaic module, comprising a frame and a fixing mechanism, a glass clamping mechanism, a pulse separation mechanism, and a first heating mechanism disposed on the frame. The fixing mechanism is used to fix the decommissioned photovoltaic module, the glass clamping mechanism is used to clamp the glass on the decommissioned photovoltaic module, the first heating mechanism is used to heat the decommissioned photovoltaic module, and the pulse separation mechanism is used to generate a pulse airflow and separate the glass on the decommissioned photovoltaic module. The frame is provided with a first displacement mechanism and a second displacement mechanism, and the fixing mechanism is disposed on the first displacement mechanism. The first displacement mechanism is used to control the fixing mechanism to move closer to or away from the pulse separation mechanism, and the second displacement mechanism is used to drive the glass clamping mechanism to move towards the decommissioned photovoltaic module.

[0006] The pulse separation mechanism includes a separation blade and a gap sealing mechanism. One end of the separation blade has a cutting edge, and a gas chamber is disposed within the blade body, connected to an external gas source. An air outlet is located at the end of the blade near the cutting edge, connected to the gas chamber. The gap sealing mechanism is disposed within the gas chamber and is used to contact the displaced decommissioned photovoltaic module. It controls the intermittent opening or closing of the air outlet, causing high-pressure pulsed gas to be ejected from the outlet, thus separating the glass on the decommissioned photovoltaic module. Compared to existing technologies, this solution uses an intermittent mechanism to contact the photovoltaic module and controls the gap mechanism to intermittently close or open the air outlet, enabling the ejection of high-pressure pulsed gas. This better cuts the EVA film between the decommissioned photovoltaic module and the glass, improving the separation efficiency of the decommissioned photovoltaic module.

[0007] To achieve an intermittent sealing mechanism, in some preferred embodiments, the intermittent sealing mechanism includes a cam rotatably mounted inside the gas chamber. The outer contour surface of the cam is positioned opposite the gas outlet. The outer contour surface of the cam has a sealing section and a gas outlet section. The outer contour surface of the sealing section contacts and seals the gas outlet, while a gap exists between the outer contour surface of the gas outlet section and the gas outlet. A transmission mechanism is provided on the cam, which is used to contact the crystalline silicon wafer surface of the retired photovoltaic module and drive the cam to rotate. By setting the cam inside the gas chamber, the sealing section and the gas outlet section on the cam can intermittently seal and open the gas outlet when rotating. During sealing, the gas pressure inside the gas chamber is stored, and during opening, the stored gas is released, resulting in a high-pressure pulse gas being ejected from the gas outlet. This gas can cut the heated EVA film, achieving glass separation.

[0008] To implement the transmission mechanism, in some preferred embodiments, the transmission mechanism includes a roller rotatably mounted on the separating blade body, and the roller is connected to a cam drive. By rotatably mounting the roller on the separating blade body and driving the roller to the cam drive, that is, when the roller contacts the decommissioned photovoltaic module, it drives the cam to rotate, thereby intermittently opening or blocking the air outlet.

[0009] To better cut the EVA film, in some preferred embodiments, a second heating mechanism for heating the gas is provided between the gas chamber and an external gas source. The second heating mechanism heats the gas in the gas chamber, and a high-temperature, high-pressure pulsed gas is ejected from the gas outlet, improving the separation efficiency of the decommissioned photovoltaic modules.

[0010] Because retired photovoltaic modules of different specifications have varying thicknesses, the positions of the glass also differ. To ensure the precise positioning of the separating blade during glass separation, in some preferred embodiments, a third displacement mechanism is provided on the frame to control the displacement of the separating blade along the frame height. By controlling the displacement of the separating blade along the frame height through this third displacement mechanism, the blade is positioned as required, satisfying the separation needs of retired photovoltaic modules of different specifications and improving the applicability of the equipment.

[0011] To implement the third displacement mechanism, in some preferred embodiments, the third displacement mechanism includes a third screw and a third motor. The third motor is fixedly mounted on the frame, and the third screw is rotatably mounted on the frame. The third screw is drively connected to the third motor, and the separating blade is threadedly connected to the third screw. The third motor drives the third screw to rotate, thereby displacing the separating blade on the frame.

[0012] To achieve the fixing mechanism, in some preferred embodiments, the fixing mechanism includes a first negative pressure suction cup that is in communication with an external negative pressure source.

[0013] To realize the first displacement mechanism, in some preferred embodiments, the first displacement mechanism includes a lower displacement platform, a first screw and a first motor. The first negative pressure suction cup is disposed on the lower displacement platform, the first motor is fixedly mounted on the frame, the first screw is rotatably mounted on the frame, the first screw is drivenly connected to the first motor, and the lower displacement platform is threadedly connected to the first screw.

[0014] In order to realize the glass clamping mechanism, in some preferred embodiments, the glass clamping mechanism includes a second negative pressure suction cup that is connected to an external negative pressure source.

[0015] To realize the second displacement mechanism, in some preferred embodiments, the second displacement mechanism includes a linear motor mounted on the frame, a second negative pressure suction cup slidably mounted on the frame, and the second negative pressure suction cup is disposed on the displacement end of the linear motor.

[0016] The beneficial effects of this invention are as follows: The separation device for completely separating retired photovoltaic module glass utilizes an intermittent mechanism in contact with the photovoltaic module. The intermittent sealing or opening of the gas outlet by the intermittent mechanism allows for the ejection of high-pressure pulsed gas, which effectively cuts the EVA film between the retired photovoltaic module and the glass, improving the separation efficiency of the retired photovoltaic module, maintaining the integrity of the glass and silicon wafer, and enabling rapid separation without environmental pollution and low energy consumption. This avoids the problems of existing physical pyrolysis methods, which primarily rely on blades and wire ropes to cut the adhesive layer. However, the EVA film is very thin, making it difficult for blades and wire ropes to cut into it completely and accurately, easily causing scratches and damage to the recycled items, requiring further sorting, increasing production steps, and reducing recycling efficiency.

[0040] like Figure 1-10 As shown, a separation device for completely separating the glass of a decommissioned photovoltaic module includes a frame 1, a fixing mechanism 2, a glass clamping mechanism 3, a pulse separation mechanism 4, and a first heating mechanism 5. The fixing mechanism 2, the glass clamping mechanism 3, the pulse separation mechanism 4, and the first heating mechanism 5 are all mounted on the frame 1. The fixing mechanism 2 is used to fix the decommissioned photovoltaic module. The glass clamping mechanism 3 is used to clamp the glass on the decommissioned photovoltaic module and play an auxiliary separation role. The first heating mechanism 5 is used to heat the EVA film between the glass on the decommissioned photovoltaic module and the crystalline silicon wafer and the backsheet. The pulse separation mechanism 4 is used to generate pulse airflow and separate the glass on the decommissioned photovoltaic module. The frame 1 is provided with a first displacement mechanism 6 and a second displacement mechanism 7. The fixing mechanism 2 is mounted on the first displacement mechanism 6. The first displacement mechanism 6 is used to control the fixing mechanism 2 to move longitudinally along the frame 1 and move closer to or away from the pulse separation mechanism 4. The second displacement mechanism 7 is used to drive the glass clamping mechanism 3 to move longitudinally along the frame 1 and move closer to or away from the decommissioned photovoltaic module.

[0041] The pulse separation mechanism 4 includes a separation blade 401 and a gap sealing mechanism. The separation blade 401 has a blade 4011 at one end near the fixing mechanism 2. A closed air chamber 4012 is provided inside the separation blade 401, which is connected to an external air source. An air outlet 4013 is opened at one end of the separation blade 401 near the blade 4011, which is connected to the air chamber 4012. The gap sealing mechanism is located inside the air chamber 4012. The gap sealing mechanism is used to contact the displaced retired photovoltaic module and control the air outlet 4013 to open or close intermittently, so that the air outlet 4013 sprays out high-pressure pulse gas. The high-pressure pulse gas cuts the EVA film, thereby separating the glass on the retired photovoltaic module.

[0042] The gap sealing mechanism includes a cam 402 and a transmission mechanism. The cam 402 is rotatably mounted in the air chamber 4012. The outer contour surface of the cam 402 is opposite to the air outlet 4013. The outer contour surface of the cam 402 has a sealing section 4021 and an air outlet section 4022. The outer contour surface of the sealing section 4021 contacts and seals the air outlet 4013. Therefore, the sealing section 4021 is the maximum stroke point of the cam 402. The sealing section 4021 is arc-shaped and can seal the air outlet 4013 for a period of time. The duration of the seal depends on the usage. The length of the blocking section 4021 of the cam 402 is designed. There is a gap between the outer contour surface of the air outlet section 4022 and the air outlet 4013. The air outlet section 4022 is the other stroke of the cam 402. The other stroke can be the intermediate transition stroke or the minimum stroke. The transmission mechanism is set on the cam 402. The transmission mechanism is used to contact the crystalline silicon wafer surface of the retired photovoltaic module and drive the cam 402 to rotate. The transmission mechanism includes a roller 403. The roller 403 is rotatably mounted on the separating blade body 401. The roller 403 and the cam 402 are connected to each other through a gear set.

[0043] A second heating mechanism 404 for heating the gas is provided between the gas chamber 4012 and the external gas source. In this embodiment, the second heating mechanism 404 is a pipe heater in the prior art, which can assist in heating the gas passing through the pipe heater. Meanwhile, the first heating mechanism 5 is fixed on the frame 1 by a support frame. The first heating mechanism 5 is a laser, which emits laser light to heat a region on the decommissioned photovoltaic module.

[0044] The frame 1 is provided with a third displacement mechanism 8 for controlling the displacement of the separating blade 401 along the height of the frame 1. The third displacement mechanism 8 includes a third screw 801 and a third motor 802. The third motor 802 is fixedly installed on the frame 1, and the third screw 801 is rotatably installed on the frame 1. The third screw 801 is connected to the third motor 802 in a transmission connection, and the separating blade 401 is threadedly connected to the third screw 801.

[0045] The fixing mechanism includes a first negative pressure suction cup 201, which is connected to an external negative pressure source. The first displacement mechanism 6 includes a lower displacement platform 601, a first screw 602, and a first motor 603. The first negative pressure suction cup 201 is fixed on the upper surface of the lower displacement platform 601 and faces upward. The lower displacement platform 601 slides longitudinally on the frame 1. The first motor 603 is fixedly installed on the frame 1. The first screw 602 is rotatably installed on the frame 1 and is connected to the first motor 603 in a transmission connection. The lower displacement platform 601 is threadedly connected to the first screw 602.

[0046] The glass clamping mechanism 3 includes an upper displacement platform, a clamping platform, a second negative pressure suction cup 301, a second motor, and a second screw. The second negative pressure suction cup 301 is connected to an external negative pressure source. The second negative pressure suction cup 301 is fixed on the clamping platform and faces downward. The clamping platform slides along the height direction on the upper displacement platform. The second screw is rotatably mounted on the upper displacement platform. The second motor is fixedly mounted on the upper displacement platform. The output end of the second motor is connected to the second screw. The second screw is threadedly connected to the clamping platform. The second displacement mechanism 7 includes a linear motor mounted on the frame 1. The displacement platform on the second negative pressure suction cup 301 slides along the longitudinal direction of the frame 1 on the frame 1. The upper displacement platform is mounted on the displacement end of the linear motor.

[0047] In use, the aforementioned separation device for completely separating the glass of decommissioned photovoltaic modules involves the decommissioned photovoltaic module being held and fixed by the first negative pressure suction cup 201 on the fixing mechanism 2. Then, the first motor 603 at the first displacement mechanism 6 drives the first screw 602 to rotate, causing the lower displacement platform 601 of the fixing mechanism 2 to move towards the separation blade 401. The laser at the first heating mechanism 5 is located above the decommissioned photovoltaic module and emits a planar laser beam downwards to locally heat the entire horizontal direction of the module. The linear motor at the glass clamping mechanism 3 operates, causing the upper displacement platform to move on the frame 1. Simultaneously, the second motor on the upper displacement platform drives the screw to rotate, causing the clamping platform to move downwards and the second negative pressure suction cup 301 to move downwards until the second negative pressure suction cup 301 holds the glass on the decommissioned photovoltaic module. Furthermore, the separation blade 401 at the pulse separation mechanism 4 is driven by the third motor 802 to rotate the third screw 801, causing the separation blade 401 to move and be positioned as required. The blade 4011 of the separation blade 401 faces the gap between the glass and the silicon wafer, and the air outlet 4013 also faces the gap. After the second displacement mechanism 7 drives the second negative pressure suction cup 301 to open a 3-5mm slit between the glass and the silicon wafer, the blade 4011 of the separation blade 401, together with the high temperature and high pressure pulse air knife from the air outlet 4013, enters the slit. At the same time, as the first displacement mechanism 6 drives the fixing mechanism 2 to slowly move towards the separation blade 401, the roller 403 contacts the upper surface of the silicon wafer. The contact drive gear drives the cam 402 to rotate within the air chamber 4012, causing the blocking section 4021 and the air outlet section 4022 of the cam 402 to alternately correspond to the air outlet 4013, thus blocking or opening the air outlet 4013 and achieving the ejection of pulsed high-temperature and high-pressure gas from the air outlet. Meanwhile, the gas inside the air chamber 4012 is heated to 180-200°C by the second heating mechanism 404, which can further dissolve and remove the cooled EVA film, thereby allowing the upper glass to be peeled off completely and without damage.

[0048] The specific steps are as follows:

[0049] Step 1: The system is reset and returns to zero. The retired photovoltaic module is placed on the fixing mechanism 2. The back panel is held and fixed by the first negative pressure suction cup 201. The first displacement mechanism 6 drives the fixing mechanism 2 to move towards the pulse separation mechanism 4. The first heating mechanism 5 locally heats the EVA film.

[0050] Step 2: When the decommissioned photovoltaic module is moved to the bottom of the first heating mechanism 5, the decommissioned photovoltaic module is detected by the ball bar detection device, and the detection information is fed back to the control unit. The control unit controls the pulse separation mechanism 4 to move along the Z-axis of the frame 1 and makes the blade 4011 aligned with the EVA film between the glass and the silicon wafer of the decommissioned photovoltaic module.

[0051] Step 3: When the head of the decommissioned photovoltaic module moves directly under the laser, the laser begins to preheat. After about 10 seconds of preheating, the temperature of the beam emitted by the laser reaches 180-200℃. At this time, the first displacement mechanism 6 drives the fixing mechanism 2 to move the decommissioned photovoltaic module forward at a speed of 5mm / s and perform local heating.

[0052] Step 4: When the travel of the heating zone on the retired photovoltaic module reaches 60mm, the retired photovoltaic module is at the set position. The second negative pressure suction cup 301 of the glass clamping device descends through the second displacement mechanism 7 and sucks up the glass of the retired photovoltaic module. After sucking up the glass, the glass is slowly pried up at a speed of 0.06mm / s. At the same time, the linear motor drives the upper displacement platform to move synchronously with the retired photovoltaic module in the direction of displacement.

[0053] Step 5: When the decommissioned photovoltaic module reaches the cutting position, a cut has been made between the glass and the silicon wafer. As the decommissioned photovoltaic module moves, the blade 4011 of the separating blade 401 is precisely inserted along the cut. At the same time, the roller 403 presses against the upper surface of the silicon wafer and drives the roller 403 to rotate, realizing the continuous rotation of the cam 402. The air outlet realizes the pulse of high-pressure gas. The gas inside the gas chamber 4012 is heated to 180-200℃ by the gas heater to form a high-temperature and high-pressure pulse air knife, which can further dissolve and remove the cooled EVA film. The glass gradually separates from the silicon wafer and the backsheet. The glass moves above the separating blade 401 and is recycled. The silicon wafer and the backsheet move below the separating blade 401 and enter the next process of recycling the valuable metal materials inside the silicon wafer.

[0054] The above description, based on the preferred embodiments of the present invention, provides inspiration. Those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
