Description

Technical Field

[0001] This utility model relates to the field of manufacturing equipment technology in the photovoltaic industry, and in particular to a silver paste recovery device. Background Technology

[0002] In the production process of the photovoltaic industry, silver paste scraping and transfer is a key process. It usually requires first etching a specific pattern onto a carrier to form a groove, then applying silver paste to the entire carrier, and then using a scraper to scrape off the paste on the surface of the carrier, leaving only the silver paste in the groove to achieve pattern transfer. However, silver paste itself has low activity, and after being applied to the carrier, it must be processed and recycled by the scraper on the recycling equipment before it can be reused.

[0003] Existing silver paste recycling methods generally suffer from problems such as low recycling efficiency, incomplete silver paste recycling, and poor cleaning effect on the squeegee. Furthermore, if too much silver paste remains on the squeegee, it will cause silver paste to accumulate at the starting point of the squeegee on the carrier board, which will seriously affect the subsequent transfer accuracy and product quality.

[0004] Currently, it is difficult to meet the growing demand of the photovoltaic industry for efficient recycling and high-quality production of silver paste.

[0005] In conclusion, there is an urgent need for a silver paste recovery device to solve the above problems. Utility Model Content

[0008] Furthermore, the scraping module (including the linear motor, the rotary motor, and one or more scrapers) and the recycling module (including a pair of clamping cylinders and one or more shovels connected to the output end of the clamping cylinders) are integrated on the base plate.

[0009] Furthermore, the cutting edge of the shovel is made of a special wear-resistant material.

[0010] Furthermore, the shape and size of the scraper can be customized according to the specific specifications of the carrier plate and the coating requirements.

[0011] Furthermore, both the linear motor and the rotary motor are connected to an advanced control system.

[0012] Furthermore, the clamping force of the clamping cylinder can be flexibly adjusted by a dedicated air pressure regulating device.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example: A silver paste recovery device, such as Figures 1-4As shown, the system includes a base plate 1, a mounting bracket 2, a linear motor 3, a mounting plate 301, a rotary motor 4, a scraper 5, a fixing bracket 6, a clamping cylinder 7, a contact block 8, a scraper 9, and a recovery plate 10. The base plate 1 serves as the mounting carrier for the parts. The scraping module (including the linear motor 3, the rotary motor 4, and one or more scrapers 5) and the recovery module (including a pair of clamping cylinders 7 and one or more scrapers 9 connected to the output end of the clamping cylinders 7) are integrated on the base plate 1, facilitating rapid switching and efficient connection between the scraper's working state and the recovery state. The upper side of the base plate 1... A mounting bracket 2 is connected, on which a linear motor 3 is bolted. A mounting plate 301 is connected to the output end of the linear motor 3, and a rotary motor 4 is bolted to the mounting plate 301. Both the linear motor 3 and the rotary motor 4 are connected to an advanced control system for automating and intelligently operating the device. A scraper 5 is rotatably and detachably connected to the mounting plate 301. The left end of the scraper 5 is connected to the output shaft of the rotary motor 4 via a coupling. The shape and size of the scraper 5 can be customized according to the specific specifications of the carrier plate and the coating requirements. This design allows for wide application in various photovoltaic manufacturing scenarios. A mounting bracket 6 is connected to the side of the base plate 1, located behind the mounting frame 2. Clamping cylinders 7 are symmetrically mounted on the mounting bracket 6. The clamping force of the clamping cylinders 7 can be flexibly adjusted via a dedicated air pressure regulating device to accommodate silver pastes of different thicknesses and viscosities. A contact block 8 is connected to the telescopic rod of the clamping cylinder 7. Scrapers 9 are symmetrically slidably connected to the mounting bracket 6, with each scraper 9 connected to the corresponding telescopic rod of the clamping cylinder 7. A scraper 5 is located between the two scrapers 9. The cutting edge is made of a special wear-resistant material to improve the service life of the scraper 9. A recycling plate 10 is connected to the contact block 8. The recycling plate 10 is located in front of the scraper 9. The control system controls the rotary motor 4 to drive the scraper 5 to rotate, thereby changing the orientation of the scraper 5. The linear motor 3 controls the rotary motor 4 and the scraper 5 to move up and down, and scrape the material onto the carrier plate. The clamping cylinder 7 controls the clamping action. The scraper 9 on both sides thoroughly cleans the slurry on the scraper, and the recycling plate 10 collects it, thereby achieving effective recovery of silver paste.

[0022] When this device is needed, the scraper 9 is initially in the open state. The control system controls the fixing device to move the carrier plate above the scraper 5. According to the requirements of the carrier plate, the corresponding type of scraper 5 is installed on the mounting plate 301. Then, the linear motor 3 is started. The output end of the linear motor 3 drives the mounting plate 301, the rotary motor 4, and the scraper 5 to move upward. After the scraper 5 is separated from the scraper 9, the rotary motor 4 is started. The output shaft of the rotary motor 4 rotates, driving the scraper 5 to rotate upward. After the scraper 5 rotates to a suitable angle, the rotary motor 4 is stopped. The above operation can change the orientation of the scraper 5. The linear motor 3 is then controlled to move the scraper 5 upward. When the scraper 5 contacts the surface of the carrier plate, the scraper 5 scrapes off the slurry from the surface of the carrier plate. The slurry sticks to the surface of the scraper 5. After scraping is completed, the scraping is finished. The control system controls the fixed equipment to move the carrier plate to the collection area. Then, it controls the rotary motor 4 to operate in reverse so that the scraper 5 faces downward. The control system then controls the rotary motor 4 to shut down. The control system then controls the activation of the two clamping cylinders 7. The extension rods of the two clamping cylinders 7 move, causing the two scrapers 9 to move towards each other and close. The control system then controls the clamping cylinders 7 to stop operating. The linear motor 3 is then controlled to operate in reverse so that the above components move downward, causing the scraper 5 to return to between the two scrapers 9. The scrapers 9 on both sides thoroughly clean the slurry on the scraper 5, leaving the slurry on the recovery plate 10. The above operation can achieve effective recovery of silver paste. The extension rods of the clamping cylinders 7 are controlled to move in reverse so that the two scrapers 9 move in opposite directions and open. The carrier plates are then operated in the same way to achieve recovery. Finally, the slurry on the recovery plate 10 is processed.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
