Description

Technical Field

[0001] This utility model relates to a uniform solder paste coating device for LED strip production, belonging to the technical field of LED strip production. Background Technology

[0002] LED light strips require multiple processing steps during production, one of which involves tinning the copper wires on the mold. Tinning makes it easier to solder the LED chips onto the copper wires later.

[0003] Currently, in the solder paste application process of LED strip production, the LED strip is laid flat on a conveyor belt, and then a large amount of solder paste is applied to the copper wires on the back of the LED strip using a brush. The solder paste tends to accumulate on both sides of the brush edge, making it difficult to clean and resulting in solder paste waste. Furthermore, the accumulated solder paste cannot be evenly coated on the back of the LED strip, easily causing more or less solder paste residue, which affects the drying process in the next step. Therefore, there is an urgent need for a solder paste uniform coating device for LED strip production to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a uniform solder paste coating device for LED strip production, thereby solving the problems mentioned in the background section. This invention has a reasonable structure and is easy to operate. It can not only effectively save solder paste usage and improve utilization, but also facilitate the cleaning of accumulated solder paste on both sides of the conveyor belt, ensuring uniform coating on every part of the back of the LED strip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform solder paste coating device for LED strip production, comprising a lifting control rod, a main drive motor, a solder paste spraying pipe, auxiliary components, a coating component, a mounting plate, a mounting interface, a fixing screw, a threaded post, a threaded ring, and an internal thread.

The solder paste spraying pipe is fixed to the side of the main drive motor, and auxiliary components are mounted on both the left and right sides of the main drive motor. The threaded post passes through the mounting interface, and the threaded post... A fixing screw head is installed on the top, and a threaded ring is also provided at the bottom of the threaded column. The coating assembly is installed on the mounting interface on the left side of the drive main motor. The coating assembly includes a coating pusher plate, an anti-stick layer, and a threaded interface. An anti-stick layer is provided on the front end of the coating pusher plate, and a threaded interface is provided on the first mounting rod at the rear end of the coating pusher plate. The auxiliary assembly includes a side fixing groove, a connecting rod, a scraper, a second mounting rod, an inner bearing, and auxiliary rollers. The side fixing groove is assembled on the left and right sides of the drive main motor, and a connecting rod is connected to the side fixing groove. A scraper is assembled at the bottom of the connecting rod. Auxiliary rollers are installed on the left and right ends of the second mounting rod through the inner bearing.

[0006] Furthermore, the second mounting rod is the same size as the first mounting rod on the rear end of the applicator, and threaded interfaces are also provided on both the left and right ends of the second mounting rod.

[0007] Furthermore, the bottom of the application plate, the scraper, and the auxiliary roller are all on the same horizontal plane.

[0008] Furthermore, the threaded ring at the bottom of the threaded column has an internal thread that matches the threaded interface.

[0009] Furthermore, the side fixing groove is welded to the left and right sides of the drive motor, and the scraper connected to the side fixing groove is chamfered with the inclined surface facing inward.

[0010] Furthermore, the threaded block at the bottom of the fixed screw head matches the threaded groove specification of the threaded column.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a uniform solder paste coating device for LED light strip production. Because this utility model adds a scraper, a second mounting rod, an inner bearing, an auxiliary roller, a coating pusher, an anti-stick layer, and a threaded interface, the scraper with a chamfered shape and an inward inclined surface helps to scrape off the solder paste accumulated on both sides of the conveyor belt. The solder paste will then re-enter the middle area for uniform coating by the coating pusher. The auxiliary roller is set to press and stabilize the edge of the LED light strip in front, ensuring that the light strip is flat during solder paste coating. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5This utility model provides a technical solution: a uniform solder paste coating device for LED light strip production, including a lifting control rod 1, a main drive motor 2, a solder paste spraying pipe 3, auxiliary components 4, a coating component 5, a fixed mounting plate 6, a mounting interface 7, a fixing screw head 8, a threaded post 9, a threaded ring 10, and an internal thread 11. The bottom of the lifting control rod 1 is connected to the top of the main drive motor 2, and fixed mounting plates 6 are provided on both the left and right sides of the bottom of the main drive motor 2. The fixed mounting plates 6 have multiple mounting interfaces 7. The solder paste spraying pipe 3 is fixed to the side of the main drive motor 2, and auxiliary components 4 are assembled on both the left and right sides of the main drive motor 2. The threaded post 9 passes through the mounting interface 7, and a fixing screw head 8 is installed on the top of the threaded post 9. A threaded ring 10 is also provided at the bottom. The coating assembly 5 is installed on the mounting interface 7 on the left side of the drive main motor 2. The coating assembly 5 includes a coating pusher plate 51, an anti-stick layer 52, and a threaded interface 53. An anti-stick layer 52 is provided on the front end of the coating pusher plate 51, and a threaded interface 53 is provided on the first mounting rod at the rear end of the coating pusher plate 51. The auxiliary assembly 4 includes a side fixing groove 41, a connecting rod 42, a scraper 43, a second mounting rod 44, an inner bearing 45, and an auxiliary roller 46. The side fixing groove 41 is assembled on the left and right sides of the drive main motor 2, and a connecting rod 42 is connected to the side fixing groove 41. A scraper 43 is assembled at the bottom of the connecting rod 42. The auxiliary roller 46 is installed on the left and right ends of the second mounting rod 44 through the inner bearing 45.

[0021] As the first embodiment of this utility model: the threaded block at the bottom of the fixing screw head 8 matches the threaded groove specification of the threaded column 9. This design, by setting the top of the threaded column 9 as a detachable fixing screw head 8 and threaded groove, facilitates the disassembly and assembly of the first mounting rod and the second mounting rod 44. The side fixing groove 41 is welded to the left and right sides of the drive main motor 2, and the scraper 43 connected to the side fixing groove 41 is chamfered with the inclined surface facing inward. The bottom of the applicator 51, the scraper 43, and the auxiliary roller 46 are all on the same horizontal plane. This design, by setting the scraper 43 with a chamfered shape and the inclined surface facing inward, facilitates the disassembly and assembly of the first mounting rod and the second mounting rod 44. The plate 43 helps to scrape off the solder paste accumulated on both sides of the conveyor belt, and the solder paste will re-enter the back of the light strip so that the coating pusher 51 can evenly apply it. The threaded ring 10 at the bottom of the threaded post 9 has an internal thread 11 that matches the threaded interface 53. The second mounting rod 44 has the same size as the first mounting rod at the rear end of the coating pusher 51, and the left and right ends of the second mounting rod 44 are also provided with threaded interfaces 53. This design allows the second mounting rod 44 and the first mounting rod to be installed with the threaded ring 10 by screwing in the thread, thereby realizing the horizontal pushing and coating of solder paste by the coating pusher 51 and the auxiliary roller 46.

[0022] As a second embodiment of this utility model: the main drive motor 2 of the LED strip production equipment is connected to the lifting control rod 1 to adjust the overall height. When applying solder paste to the back of the LED strip, the strip is pushed by the conveyor belt, and the solder paste spraying tube 3 sprays the solder paste onto the back of the strip. Then, the auxiliary roller 46 on the first mounting rod will press and stabilize the edge of the strip. The coating pusher 51 on the second mounting rod 44 will flatten the sprayed solder paste and then press it to make the back of the strip evenly coated. However, the solder paste will accumulate on both sides when flattened. At this time, the scraper 43 can scrape the solder paste accumulated on both sides and scrape it back to the middle area, where it is flattened again by the coating pusher 51. The coating pusher 51 is provided with an anti-stick layer 52, which can effectively prevent the solder paste from sticking and being wasted.
