Description

Technical Field

[0002] Photovoltaic glass consists of glass, solar cells, film, back glass, and special metal wires. It has a wide range of applications, such as solar smart windows, solar pavilions, photovoltaic glass building roofs, and photovoltaic glass curtain walls. It is divided into two main categories: crystalline silicon photovoltaic glass and thin-film photovoltaic glass. The former is further divided into monocrystalline silicon and polycrystalline silicon, and is commonly used as a curtain wall material. Photovoltaic glass is a special type of glass that converts natural light into electrical energy by encapsulating solar cell modules within glass layers. It typically uses low-iron tempered glass or double-layered glass, coated with an anti-reflective coating and a transparent conductive layer. The production process of photovoltaic glass requires the coating of anti-reflective coatings and transparent conductive layers on the surface.

[0003] In the current photovoltaic glass production coating process, due to the different shapes and structures of photovoltaic glass, it is necessary to constantly replace the support structure to adapt to it, and to finely adjust the replacement support structure, which is time-consuming and labor-intensive and affects the processing efficiency. During the coating process, some coating is prone to dripping and running along the edge of the photovoltaic glass, resulting in coating waste and contamination of other surfaces of the photovoltaic glass. This requires a cleaning process before coating other surfaces, which affects the overall photovoltaic glass production efficiency.

[0015] A method for operating a coating equipment for photovoltaic glass production includes the following steps:

[0016] Step 1: The servo motor drives the rotating column to decelerate and rotate via the transmission component. The picking robot arm rotates with the rotating column. When a single picking robot arm moves close to the photovoltaic glass to be processed that is slowly descending on the conveyor belt, the second cylinder drives the pneumatic gripper to extend to the center of the bottom of the photovoltaic glass to be processed. The pneumatic gripper opens with air circulation, and the picking suction cup adsorbs the photovoltaic glass to be processed. The picking robot arm is intermittently rotated by the rotating column to above the main suction cup. The side suction cup and the main suction cup are driven by the lifting cylinder. The main suction cup first rises, passes through the middle of the pneumatic gripper, and contacts the center of the bottom of the photovoltaic glass to be processed for initial adsorption and fixation. Multiple sets of... The side suction cup is driven by the first cylinder to approach the photovoltaic glass to be processed. After the main suction cup rises, it is driven by the lifting cylinder to approach and adsorb the photovoltaic glass to be processed. During the process of the main suction cup contacting the photovoltaic glass to be processed and adsorbing and locking it, the material picking suction cup is reset and disconnected from the adsorption and locking of the photovoltaic glass to be processed. The second cylinder drives the pneumatic gripper to reset and is driven by the rotating column to disengage from the top of the turntable. After the photovoltaic glass to be processed is adsorbed, locked and fixed, the servo motor drives the turntable to rotate clockwise at a uniform speed through the coupling. The turntable drives the photovoltaic glass to be processed, which is adsorbed and locked at multiple points, to rotate synchronously through the main suction cup and multiple sets of side suction cups.

[0017] Step 2: During the process of the photovoltaic glass to be processed being fixed by multiple adsorption points, multiple sets of fourth cylinders inside the sealing ring drive the traction frame to approach the photovoltaic glass to be processed until the traction frame and the support block contact the outer wall and bottom edge of the photovoltaic glass to be processed. The elastic membrane is moved closer to the photovoltaic glass to be processed by the traction frame. The rubber strip in the middle of the elastic membrane shrinks as the multiple sets of traction blocks approach each other. The holes in the middle of the elastic membrane shrink synchronously and adhere to the outer wall of the photovoltaic glass to be processed. When the turntable rotates, the drive motor drives the sealing ring and the turntable to rotate synchronously and uniformly through the meshing of the rotating teeth and the tooth groove. The limiting convex ring is slidably connected to multiple sets of limiting slides.

[0018] Step 3: The electric push rod drives the moving block to move axially along the slide groove. The moving block drives the sliding main arm to approach the photovoltaic glass to be processed along the slide groove axis. The rotary motor drives the sliding auxiliary arm to rotate along the sliding main arm through the output end until the spray nozzle is separated from the sliding main arm and faces the photovoltaic glass to be processed. The metering pump draws paint from the paint tank and transports it to the spray nozzle through the pipeline. The spray nozzle guides the paint to be sprayed on the top surface of the photovoltaic glass to be processed.

[0019] Step 4: Inside the lifting frame, the first push cylinder drives the sliding beam rod to slide down along the Y-axis. Inside the sliding beam rod, the second push cylinder drives the limiting block to move laterally along the X-axis until the scraper moves laterally above the photovoltaic glass to be processed. The output end of the micro motor is threaded with the lead screw and drives the sliding upright rod to slide down along the Y-axis along the middle of the limiting block until the scraper contacts the photovoltaic glass to be processed. The output end of the drive motor drives the scraper to rotate counterclockwise along the surface of the photovoltaic glass to be processed, and evenly scrapes the coating sprayed on the surface of the photovoltaic glass to be processed. The sliding upright rod moves back and forth along the sliding beam rod through the limiting block until the surface of the photovoltaic glass to be processed is evenly coated, resulting in the finished photovoltaic glass coating. Excess coating is guided by the scraper to fall onto the elastic membrane. The electric push rod is driven by the third cylinder to bring the suction port close to the elastic membrane. The suction pump is connected to the suction port and the waste bin through the fittings. The suction port is sucked up by the suction force of the suction pump and enters the waste bin.

[0020] The beneficial effects of this invention are:

[0021] This invention utilizes a robotic arm that operates in conjunction with a turntable to transport photovoltaic glass along a fixed trajectory over the turntable and apply a coating. The main suction cup and multiple sets of side suction cups work together to hold and fix the photovoltaic glass at multiple points during the coating process, preventing the photovoltaic glass from shaking or tilting due to the coating process, and improving the uniformity of the coating thickness and the coating efficiency.

[0022] The sealed ring-assisted turntable rotates synchronously to perform temporary edge attachment treatment on the photovoltaic glass that has been adsorbed and fixed. This helps to collect excess paint during the photovoltaic glass coating process and prevents excess paint from dripping and flowing along the edges of the photovoltaic glass, causing pollution and waste of paint on the rest of the photovoltaic glass surface. The suction port is used to assist the waste bin to actively absorb and collect excess paint on the elastic membrane, thereby realizing the recycling of excess material and reducing material costs.

[0023] The scraping component is used with an auxiliary turntable and sealing ring. The multi-axis flexible adjustment scraper contacts the photovoltaic glass during the processing, and performs uniform scraping treatment on the surface of the sprayed coating. With the help of a metering pump, the amount of coating is precisely controlled, so as to achieve precise control of the material used in the coating process of photovoltaic glass and reduce the loss of coating due to adhesion of coating tools during the coating process.

[0024] Through the coordinated operation of the base, material handling robotic arm, feeding assembly, ring drive frame, sealing ring, and scraping assembly, it can achieve both stable and fixed-track conveying of photovoltaic glass and multi-point pneumatic adsorption support and fixation. It can also achieve precise quantitative spraying of coating and residual material suction recovery, as well as flexible adjustment of the scraper through multi-axis linkage to uniformly coat the photovoltaic glass with coating. Furthermore, it can utilize elastic molds to temporarily attach and protect the edges of the photovoltaic glass during the processing. Attached Figure Description

[0036] Example 1

[0037] This embodiment addresses the problem that in the existing photovoltaic glass production coating process, due to the different shapes and structures of photovoltaic glass, it is necessary to constantly replace the matching support structure and perform fine-tuning on the replaced support structure, which is time-consuming, labor-intensive, and affects processing efficiency.

[0038] Please see Figure 1 - Figure 3As shown, this embodiment is a coating equipment and method for photovoltaic glass production, including a base 1, a turntable 104 rotatably connected to the top of the base 1, a main suction cup 103 installed at the center of the top of the turntable 104, multiple sets of side suction cups 102 arranged in a rectangular array on the side of the main suction cup 103, multiple sets of material-picking robotic arms 5 installed on one side of the top of the base 1 near the main suction cup 103, a rotating column 501 rotatably connected to the top of the base 1 in the middle of the multiple sets of material-picking robotic arms 5, a feeding assembly 2 near the base 1 on the side of the material-picking robotic arms 5, a first cylinder 101 connected to the side suction cups 102 embedded in the top of the turntable 104, and a connection between the bottom of the side suction cups 102 and the first cylinder 101. 01 The movable rod is sleeved and connected to the connecting block that limits the sliding on the surface of the turntable 104. The bottom of the main suction cup 103 is sleeved with a lifting cylinder 105 that is fixed to the top center of the turntable 104. The bottom of the base 1 is embedded with a servo motor 106 that is driven and connected to the turntable 104. The output end of the servo motor 106 is sleeved with a transmission component 107 that is driven and connected to the rotating column 501. The transmission component 107 consists of a belt, gears, reducers and couplings. The top outer side of the picking robot arm 5 is fixedly installed with a second cylinder 502. The end of the second cylinder 502 away from the rotating column 501 is sleeved with a pneumatic gripper 503. The top of the pneumatic gripper 503 is fixedly installed with multiple sets of picking suction cups 504.

[0039] The servo motor 106 drives the rotating column 501 to decelerate and rotate via the transmission component 107. The picking robot arm 5 rotates with the rotating column 501. When a single picking robot arm 5 moves close to the photovoltaic glass to be processed that is slowly descending on the conveyor belt, the second cylinder 502 drives the pneumatic gripper 503 to extend to the center of the bottom of the photovoltaic glass to be processed. The pneumatic gripper 503 is ventilated and opens, and the picking suction cup 504 adsorbs the photovoltaic glass to be processed. The picking robot arm 5 is intermittently rotated by the rotating column 501 to above the main suction cup 103. The side suction cups 102 and the main suction cup 103 are driven by the lifting cylinder 105. The main suction cup 103 first rises, passes through the middle of the pneumatic gripper 503, and contacts the center of the bottom of the photovoltaic glass to be processed for initial adsorption and fixation. Multiple sets of side suction cups 102 are driven by the first cylinder 101 to approach the photovoltaic glass to be processed. After the main suction cup 103 rises, they are simultaneously driven by the lifting cylinder 105 to approach and adsorb the photovoltaic glass to be processed, forming a multi-point uniform adsorption. During the process of the main suction cup 103 contacting and locking the photovoltaic glass to be processed, the material-retrieving suction cup 504 resets and disconnects the suction and locking of the photovoltaic glass to be processed. The second cylinder 502 drives the pneumatic gripper 503 to reset and is driven by the rotating column 501 to disengage from above the turntable 104. After the photovoltaic glass to be processed is suction-locked and fixed, the servo motor 106 drives the turntable 104 to rotate clockwise at a uniform speed via the coupling. The turntable 104 drives the photovoltaic glass to be processed, which is suction-locked at multiple points, to rotate synchronously via the main suction cup 103 and multiple sets of side suction cups 102. Through the linkage and mutual cooperation between the material-retrieving robotic arm 5 and the turntable 104, the photovoltaic glass is transported and conveyed along a fixed trajectory above the turntable 104 and scraped. The main suction cup 103 and multiple sets of side suction cups 102 jointly suction-support and fix the photovoltaic glass to be processed at multiple points during the scraping process, so as to prevent the photovoltaic glass from shaking and tilting due to scraping, and improve the uniformity of the scraped coating thickness and the coating efficiency.

[0040] Example 2

[0041] This embodiment addresses the problem that during the coating process, some coating easily drips and flows along the edges of the photovoltaic glass, causing coating waste and contamination of other surfaces of the photovoltaic glass. This necessitates a cleaning process before coating other surfaces, thus affecting the overall production efficiency of photovoltaic glass.

The main arm 206 moves axially along the slide groove 205 towards the photovoltaic glass to be processed. The rotary motor 207 drives the sliding auxiliary arm 208 to rotate along the sliding main arm 206 through the output end until the spray nozzle 209 disengages from the sliding main arm 206 and faces the photovoltaic glass to be processed. The metering pump 202 draws paint from the paint tank 201 and transports it to the spray nozzle 209 through the pipeline. The spray nozzle 209 guides the paint to be sprayed onto the top surface of the photovoltaic glass to be processed. The sealing ring 6 assists the turntable 104 to rotate synchronously and perform temporary edge attachment treatment on the photovoltaic glass that has been adsorbed and fixed.

The elastic membrane 602 has a hole in its middle, and the inner wall of the hole has an adhesive strip that engages with the traction frame 605. During the process of the photovoltaic glass to be processed being fixed by multi-point adsorption, multiple sets of fourth cylinders 604 inside the sealing ring 6 drive the traction frame 605 to approach the photovoltaic glass to be processed until the traction frame 605 and the support block are engaged. 606 contacts the outer wall and bottom edge of the photovoltaic glass to be processed. The elastic film moves closer to the photovoltaic glass to be processed by the traction frame 605. The adhesive strip in the middle of the elastic film contracts as multiple sets of traction blocks come together, causing the holes in the middle of the elastic film to contract synchronously and adhere to the outer wall of the photovoltaic glass to be processed.

The sliding rod 404 moves back and forth along the sliding beam rod 403 via the limit block until the surface of the photovoltaic glass to be processed is evenly coated, and the finished photovoltaic glass coating is obtained. Excess coating is guided by the scraper 406 to fall onto the elastic membrane.
