Description

Technical Field

[0001] This invention relates to the field of photovoltaic device manufacturing technology, specifically to a clamping tool for manufacturing photovoltaic components. Background Technology

[0002] In the photovoltaic industry, silicon-based ring workpieces, photovoltaic ceramic carrier disks and other devices will have processing oil, dust and tiny debris adhering to their surfaces during the manufacturing process. If the oil remains in the inner ring, gaps and micropores of the workpiece, it will directly affect the quality of subsequent processes such as coating.

[0003] Currently, the clamping devices used in the industry for such photovoltaic components mainly adopt split-type tooling equipment. Moreover, the clamping tooling mostly uses rigid jaws to clamp and position the inner ring, which can easily cause squeezing damage or scratches to the photovoltaic workpiece. At the same time, the workpiece is subjected to uneven force, which can easily lead to loosening and slippage, resulting in insufficient positioning stability and making it difficult to meet the requirements of batch continuous production. Secondly, the existing degreasing of devices mostly adopts simple soaking cleaning, which can only remove surface oil and cannot remove stubborn oil stains attached to the pores, resulting in many dead corners and incomplete cleaning.

[0004] Therefore, the present invention proposes a clamping tool for manufacturing photovoltaic components. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: This clamping fixture for manufacturing photovoltaic components features a clamping assembly inside its housing. This assembly allows for the batch clamping and positioning of annular photovoltaic devices. A U-shaped structure composed of limiting blocks and clamping blocks clamps and limits the inner ring surface of the device, improving clamping stability. Simultaneously, a limiting air cushion, limiting sleeve, fixing rod, compression spring, and through-hole work together. When the limiting air cushion is compressed by the inner ring of the annular photovoltaic device, the gas inside flows into the limiting sleeve through the through-hole, achieving dynamic pressure balance within the cavity. The flexible expansion of the limiting air cushion provides multi-point clamping and limiting of the inner ring of the device, adapting to disc-shaped devices of different inner diameters. The clamping force is uniform, effectively preventing device rotation and displacement, significantly improving clamping reliability.

[0017] This clamping fixture for manufacturing photovoltaic components integrates an oil removal component and a circulating liquid guiding component. The housing incorporates an ultrasonic transducer and a circulating liquid guiding structure. The ultrasonic transducer generates a cavitation effect in the cleaning fluid, which, combined with the cleaning agent continuously sprayed from the positioning column's outlet, forms a composite cleaning mode of ultrasonic waves and sprayed liquid flow. This allows it to penetrate deep into the pores and crevices of disc-shaped components to remove oil and impurities. It excels at cleaning fine oil stains from complex structural components, providing thorough cleaning without any blind spots. Through a linkage turntable and transmission gears, the drive motor synchronously rotates the rotating chassis and the circulating liquid guiding component. The components rotate at a uniform speed with the positioning column, ensuring even contact between the ultrasonic field and the cleaning fluid across all parts of the components, guaranteeing effective oil removal and cleaning.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 The present invention provides a technical solution: a clamping auxiliary tool for manufacturing photovoltaic components, including a housing 1, wherein a clamping component 2 and an oil removal component 3 are disposed inside the housing 1.

[0022] A filter box 302 is fixedly installed on the inner wall of the housing 1. Multiple sets of strip-shaped filter holes are evenly distributed on the surface of the filter box 302, and a filter screen 304 is fixedly embedded inside each strip-shaped filter hole. Several sets of ultrasonic transducers 303 are fixedly installed on the sides of the filter box 302 and the bottom wall of the housing 1. The ultrasonic transducers 303 are connected to multiple ultrasonic power supplies and are electrically connected to the controller panel 6. During operation, the ultrasonic transducers 303 are immersed in the cleaning fluid, utilizing high-frequency vibration to generate a cavitation effect in the liquid, which, in conjunction with the cleaning agent, achieves oil removal. The filter screen 304 can filter the returned cleaning fluid, intercepting oil particles, silica flakes, and solid impurities, preventing impurities from adhering to the surface of the ultrasonic transducers 303 and affecting the vibration effect.

[0023] A protective cover 101 is fixedly installed on the outer side of the bottom of the housing 1. Inside the protective cover 101, there is a drive mechanism 4 and a circulating liquid guiding assembly 5. The drive mechanism 4 includes a drive motor 401, which is fixedly installed on the inner bottom wall of the protective cover 101. The output shaft end of the drive motor 401 is fixedly connected to a drive gear 402. A drive sleeve 403 is rotatably mounted on the lower surface of the housing 1 through a bearing. A driven gear 404 is fixedly mounted on the surface of the drive sleeve 403. The driven gear 404 meshes with the drive gear 402. When the drive motor 401 is running, it drives the drive sleeve 403 to rotate as a whole through gear meshing.

[0024] The top of the drive sleeve 403 extends upward into the interior of the housing 1, and the top is fixedly connected to the cylindrical support shell 405. The cylindrical support shell 405, drive sleeve 403, housing 1, and rotating chassis 201 are arranged coaxially. The bottom of the cylindrical support shell 405 is rotatably connected to the bottom wall of the housing 1 through a bearing. The upper surface of the cylindrical support shell 405 is fixedly connected to the lower surface of the rotating chassis 201. When the drive sleeve 403 rotates, it can synchronously drive the cylindrical support shell 405 and the rotating chassis 201 to rotate together, thereby making the device above the rotating chassis 201 rotate at a uniform speed, allowing the device surface to come into full contact with the cleaning fluid and ultrasonic field, ensuring that the cleaning effect of the entire batch of devices is uniform and consistent.

[0025] A rotating shaft 406 is rotatably mounted on the lower surface of the housing 1 via bearings. A transmission gear 407 is fixedly mounted on the outer side of the rotating shaft 406. The transmission gear 407 meshes with the driven gear 404, and the transmission ratio between the driven gear 404 and the transmission gear 407 is set to 50:1, enabling the rotating shaft 406 to operate stably at high speed. The bottom end of the rotating shaft 406 extends downward into the interior of the protective cover 101, and the bottom end is fixedly connected to the linkage turntable 408. A reciprocating push rod 409 is rotatably connected to the lower surface of the linkage turntable 408 at an eccentric position. The rotating shaft 406 drives the linkage turntable 408 to rotate in a circular motion, and the eccentrically arranged reciprocating push rod 409 performs a reciprocating push-pull motion accordingly, providing power input to the circulating liquid guiding assembly 5. The entire drive mechanism 4 uses a single motor to centrally drive a single drive motor 401 to simultaneously realize the rotation of the device and the circulation of the cleaning liquid, without the need for an additional power source. The equipment structure is more compact, energy consumption is lower, and the degree of automation integration is higher.

[0026] The circulating liquid guiding assembly 5 includes a liquid guiding cylinder 501, which is horizontally fixed to the lower surface of the housing 1. A piston disc 502 is slidably mounted inside the liquid guiding cylinder 501. A piston rod 503 is coaxially fixedly connected to the right side of the piston disc 502. The right end of the piston rod 503 extends out of the liquid guiding cylinder 501 and is fixedly connected to a movable plate 504 at its end. A rotating seat is provided on the top right side of the movable plate 504. The end of the reciprocating push rod 409 is rotatably connected to the rotating seat through a rotating shaft. When the reciprocating push rod 409 reciprocates, it can pull the movable plate 504, the piston rod 503, and the piston disc 502 to slide back and forth inside the liquid guiding cylinder 501, thereby realizing the extraction and transportation of cleaning fluid.

[0027] The left end of the liquid guide tube 501 is fixedly embedded with an inlet conduit 507, which extends upward into the interior of the housing 1. Its output port is connected to the interior of the impurity removal filter box 302. A one-way inlet valve is fixedly installed on the body of the inlet conduit 507. The lower surface of the liquid guide tube 501 is fixedly embedded with a drain conduit 505, which is laid downward and then bent upward to extend into the interior of the cylindrical support shell 405. Three diversion horizontal pipes 506 are branched at the top of the drain conduit 505. The three diversion horizontal pipes 506 are respectively connected to the interior of the three positioning columns 202. A one-way drain valve is fixedly installed on the body of the drain conduit 505.

[0028] During the leftward movement of the piston disc 502, a negative pressure is formed inside the liquid guide cylinder 501. The cleaning fluid that has been filtered inside the housing 1 is drawn into the liquid guide cylinder 501 through the impurity removal filter box 302 and the liquid inlet pipe 507. When the piston disc 502 moves to the right, the pressure inside the liquid guide cylinder 501 increases, and the cleaning fluid is transported to the three positioning columns 202 through the drain pipe 505 and the diversion horizontal pipe 506, completing the closed-loop circulation of the cleaning fluid, realizing continuous supply of cleaning fluid, and ensuring the continuous operation of the oil removal work.

[0029] The clamping assembly 2 includes a rotating base 201, which is horizontally fixed on the top of the cylindrical support shell 405. Three positioning posts 202 are vertically fixed on the upper surface of the rotating base 201. The three positioning posts 202 are evenly distributed in a ring, which can simultaneously complete the batch clamping operation of multiple sets of devices. The single positioning post 202 has a hollow shell structure. Multiple sets of rectangular through holes 203 are formed on the side wall of the positioning post 202. All rectangular through holes 203 are symmetrically distributed on the surface of the positioning post 202 in pairs. A retaining block 204 is movably assembled inside the rectangular through hole 203. Limiting blocks 205 are fixedly connected to the upper and lower ends of the retaining block 204. The limiting blocks 205 on the upper and lower sides of the same retaining block 204 form a U-shaped structure with the retaining block 204. The limiting blocks 205 slide in contact with the inner wall of the rectangular through hole 203, which can both limit the upper and lower movement of the retaining block 204 and ensure that the retaining block 204 can slide horizontally along the rectangular through hole 203. Rubber anti-slip blocks 212 are fixedly attached to the inner surfaces of the two sets of limiting blocks 205. The two rubber anti-slip blocks 212 are symmetrically arranged on the upper and lower sides of the limiting air cushion 206. The rubber anti-slip blocks 212 prevent the device from loosening or slipping during rotation and cleaning.

[0030] A limiting air cushion 206 is fixedly connected to the side of the clamping block 204 facing outwards from the positioning post 202, and a limiting sleeve 207 is fixedly connected to the side of the clamping block 204 facing inwards from the positioning post 202. A fixing rod 208 is slidably assembled in the cavity inside the limiting sleeve 207. A vertical partition 209 is vertically fixed in the middle of the cavity inside the positioning post 202, dividing the inside of the positioning post 202 into two independent left and right chambers. One end of the fixing rod 208 away from the limiting sleeve 207 is fixedly connected to the surface of the vertical partition 209. A compression spring 210 is installed inside the limiting sleeve 207, one end of which is fixedly connected to the end of the fixing rod 208, and the other end abuts against the end face of the cavity inside the limiting sleeve 207. A through-hole 211 is opened at the middle position of the clamping block 204. The through-hole 211 connects the internal cavity of the limiting air cushion 206 and the internal cavity of the limiting sleeve 207. The through-hole 211 is located between the limiting air cushion 206 and the limiting sleeve 207, forming a complete gas communication channel.

[0031] When the annular photovoltaic device is fitted onto the outside of the positioning post 202 from the outside, the inner ring wall of the device will compress the limiting air cushion 206. The limiting air cushion 206 deforms under compression, and the gas stored inside it flows rapidly into the limiting sleeve 207 through the through-hole 211. After the gas enters the limiting sleeve 207, it changes the cavity air pressure, pushing the limiting sleeve 207 to slide inward toward the positioning post 202. At this time, the limiting sleeve 207 will simultaneously compress the internal compression spring 210, and the compression spring 210 will generate a reverse elastic force, which, together with the cavity air pressure, achieves dynamic air pressure balance. Relying on the mutual balance between air pressure and spring force, the limiting air cushion 206 always maintains an outward pressing force, providing flexible multi-point clamping and limiting of the inner ring of the annular photovoltaic device. The clamping component 2 can be adapted to various disc and ring devices with different inner diameters, making it more versatile. On the other hand, the flexible clamping force is uniform, which will not cause squeezing damage to thin, brittle, and easily cracked photovoltaic components. At the same time, the multiple limiting structures work together to completely prevent the device from shifting or rotating during the rotation cleaning process.

[0032] The degreasing assembly 3 also includes multiple sets of liquid outlet holes 301 formed on the side wall of the positioning column 202. These outlet holes 301 are evenly arranged longitudinally along the axial direction of the positioning column 202, and are staggered with the rectangular through holes 203 without interfering with each other. The positioning column 202 is a hollow cavity. After the cleaning fluid is introduced into the positioning column 202 through the diversion horizontal pipe 506, it can be sprayed outward from each outlet hole 301, directly flushing the inner ring surface, gaps, and small pores of the device. Combined with the ultrasonic cavitation effect generated by the ultrasonic transducer 303 inside the housing 1, a composite degreasing mode of ultrasonic vibration plus high-pressure spraying is formed. The ultrasonic cavitation effect can penetrate deep into the fine pores of the device to remove stubborn oil stains, and the sprayed liquid flow can promptly flush away the detached oil stains and impurities, resulting in thorough cleaning without dead angles.

[0033] The controller panel 6 installed on the outside of the housing 1 integrates operation buttons, parameter display screen, start and stop switch and other components. Multiple ultrasonic power supplies, all ultrasonic transducers 303 and drive motors 401 are electrically connected to the controller panel 6. Operators can use the controller panel 6 to set operating parameters, control the start and stop of the whole machine, and adjust ultrasonic power and motor speed.

[0034] Working principle: The operator sequentially places the photovoltaic component onto the outside of the three positioning posts 202, with the inner ring of the component initially contacting the limiting air pad 206. During the insertion process, the inner ring of the component compresses the limiting air pad 206, and the gas inside the limiting air pad 206 flows into the limiting sleeve 207 through the through air hole 211. The limiting sleeve 207 slides inward under pressure and compresses the compression spring 210. Under the dynamic balance of air pressure and spring force, the limiting air pad 206 continuously pushes the inner ring of the component outward, which, together with the rubber anti-slip blocks 212 on the upper and lower sides, completes the limiting of the component, ensuring that the component is fixed in position and does not loosen.

[0035] After the components are loaded, the degreasing cleaning agent is poured into the housing 1. Then, the drive motor 401 is started through the controller panel 6. The output of the drive motor 401 drives the drive gear 402 to rotate. The drive gear 402 meshes with the driven gear 404 and the drive sleeve 403 to rotate synchronously. The drive sleeve 403 drives the cylindrical support shell 405, the rotating base 201 and the three positioning pins 202 to rotate at a constant speed, so that all the clamped components rotate synchronously. On the other hand, the driven gear 404 meshes with the transmission gear 407 and the rotating shaft 406 to rotate at a low speed. The linkage turntable 408 at the bottom of the rotating shaft 406 rotates accordingly. The eccentrically arranged reciprocating push rod 409 pulls the movable plate 504, the piston rod 503 and the piston disc 502 to make reciprocating linear motion inside the liquid guide cylinder 501.

[0036] During the reciprocating sliding of the piston disc 502, the cleaning fluid is circulated in conjunction with the one-way inlet valve and the one-way outlet valve. After impurities are filtered through the impurity removal filter box 302 and the impurity removal filter screen 304, the cleaning fluid in the housing 1 is drawn into the liquid guide cylinder 501 through the inlet conduit 507. The cleaning fluid is then transported to the three hollow positioning columns 202 through the outlet conduit 505 and the diversion horizontal pipe 506, and then sprayed outward from the outlet hole 301 on the surface of the positioning column 202, continuously rinsing the surface and crevices of the device. Then, the multi-channel ultrasonic power supply is simultaneously turned on through the controller panel 6. After the ultrasonic transducer 303 is powered on, it generates high-frequency vibration, forming a large number of cavitation bubbles in the cleaning fluid inside the housing 1. The bubbles are continuously generated and burst, creating impacts, and using the cavitation effect to peel off the oil stains on the surface of the device and in the small pores.
