Description

Technical Field

[0001] The utility model relates to the technical field of solder paste coating, in particular to a solder paste coating device for a light strip. Background Art

[0002] With the rapid development of LED lighting technology, light strips have gained widespread application in home, commercial, and industrial lighting due to their high efficiency, long lifespan, energy conservation, and environmental friendliness. During the light strip production process, to ensure good electrical connectivity and soldering quality, a layer of solder paste is often applied to the soldering areas. To address this need, the industry has developed a variety of solder paste coating devices to meet these production requirements.

[0003] Existing solder paste coating devices for light strips often use a fixed coating template design. This involves securing the template directly to the machine using bolts and other fasteners, and precisely transferring the solder paste to the light strip through holes in the template. However, this design has significant shortcomings. First, cleaning or replacing the template to accommodate different light strip specifications is cumbersome and time-consuming, impacting production efficiency. Second, because the template easily accumulates residue after prolonged use, if it is not cleaned promptly and effectively, it can affect the uniformity and coating quality of the solder paste, thereby reducing product quality.

[0004] In order to solve the above problems, we propose a solder paste coating device for light strips, which can quickly disassemble and replace the coating template. Utility Model Content

[0005] In order to overcome the shortcomings of fixed-installed coating templates that are complicated and time-consuming to disassemble and replace, affecting production efficiency, the utility model provides a solder paste coating device for light strips, which can quickly disassemble and replace the coating template.

[0006] Technical solution: A solder paste coating device for a light strip, comprising a base, a transversely symmetrical collection box fixedly connected to the top of the base, a coating template placed on the top of the base, an electric guide rail fixedly connected to the base, a first slide slidably connected to the electric guide rail, a coating plate rotatably connected to the first slide, a drive motor fixedly connected to the first slide, the output shaft of the drive motor is fixedly connected to the coating plate, a fixing component for fixing the coating template is provided on the base, a cleaning component is provided on the first slide and the coating plate, and the cleaning component is used to clean the residual solder paste on the coating plate.

[0007] In addition, it is particularly preferred that both upper and lower ends of the coating plate are tapered to facilitate scraping the solder paste into the coating template.

[0008] In addition, it is particularly preferred that the fixing assembly includes equidistantly distributed cylinders, the equidistantly distributed cylinders are fixedly connected to the base, the telescopic ends of the cylinders are fixedly connected to the mounting seats, and the coating template is fixedly connected to two transversely symmetrical fixed blocks on both longitudinal sides, a sliding rod is slidably connected inside the fixed block, a clamping block is fixedly connected to the side of the sliding rod close to the mounting seat, and a first spring is connected between the sliding rod and the adjacent fixed block.

[0009] In addition, it is particularly preferred that the clamping block is wedge-shaped and is clamped into an adjacent mounting seat.

[0010] In addition, it is particularly preferred that the cleaning assembly includes two vertically symmetrical guide rods, the two vertically symmetrical guide rods are fixedly connected to the first slide, two vertically symmetrical mounting plates are fixedly connected to the coating plate, a screw is rotatably connected to the mounting plate, a dual-axis motor is fixedly connected between the two mounting plates, the output shaft of the dual-axis motor is fixedly connected to the adjacent screw, a second slide is slidably connected to the two guide rods, the second slide is threadedly connected to the adjacent screw, the second slide is sleeved on the coating plate, two laterally symmetrical scrapers are slidably connected to the second slide, and two longitudinally symmetrical second springs are connected between the scraper and the adjacent second slide.

[0011] In addition, it is particularly preferred that the end of the scraper close to the coating plate is tapered and fits the scraper surface.

[0012] Compared with the prior art, the utility model has the following advantages: the cylinder telescopically controls the movement of the coating template within the time limit, so as to take and place the parts of the light strip that need to be soldered, and when the coating plate moves left and right, the solder paste can be brushed onto the light strip parts below through the holes on the coating template. After the solder paste coating is completed, the scraper moves up and down to clean up the residual solder paste on the coating plate. When the coating template needs to be replaced, the control block is separated from the mounting base to release the coating template so that the coating template can be quickly replaced.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] Example 1: A solder paste coating device for a light strip, such as Figures 1-8 As shown, it includes a base 1, a collecting box 2, a coating template 3, an electric guide rail 4, a first slide 5, a coating plate 6, a driving motor 7, a fixing component and a cleaning component.

The cleaning component is used to clean the residual solder paste on the coating plate 6.

[0024] When the coating template 3 needs to be replaced, the staff can control the fixing assembly to loosen the coating template 3 so that the coating template 6 can be quickly replaced.

[0025] Example 2: Based on Example 1, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the fixing assembly includes a cylinder 8, a mounting seat 9, a fixing block 10, a sliding rod 11, a clamping block 12 and a first spring 13. The front and rear parts of the base 1 are fixedly connected to the left-right symmetrical cylinder 8, and the telescopic ends of the cylinder 8 are fixedly connected to the mounting seat 9. The front and rear sides of the coating template 3 are fixedly connected to the left-right symmetrical fixing blocks 10. The sliding rod 11 is slidingly connected in the fixing block 10. The side of the sliding rod 11 close to the mounting seat 9 is fixedly connected to the clamping block 12. The clamping block 12 is wedge-shaped and is inserted into the adjacent mounting seat 9. A first spring 13 is connected between the sliding rod 11 and the adjacent fixed block 10.

[0026] When using the device, the staff controls the cylinder 8 to extend and drive the mounting seat 9 to move upward, and the mounting seat 9 moves upward and drives the coating template 3 to move upward and lift, so that the staff can place the parts of the light strip that need to be soldered. When the light strip parts are placed, the staff controls the cylinder 8 to shorten and drive the mounting seat 9 to move downward, and the mounting seat 9 moves downward and drives the coating template 3 to move downward and reset. When the coating template 3 needs to be replaced, the staff controls the coating template 3 to move directly upward, and the coating template 3 moves upward to squeeze the blocks 12 on the left and right sides to move toward each other, and the blocks The sliding rods 11 slide toward each other when the first spring 13 is deformed, and the blocking block 12 no longer blocks the coating template 3 after the movement toward each other, so that the coating template 3 can be removed from the mounting seat 9. After the coating template 3 is disengaged from the blocking block 12, the sliding rod 11 drives the blocking block 12 to move backward and reset under the action of the first spring 13. Then the staff puts the new coating template 3 on the mounting seat 9. When the coating template 3 is installed downward, the coating template 3 will squeeze the blocking block 12 again to move, thereby making the blocking block 12 stuck in the mounting seat 9 to fix the coating template 3.

The front part of the first slide 5 is fixedly connected to the guide rod 14 which is symmetrical up and down. The front side of the coating plate 6 is fixedly connected to the mounting plate 15 which is symmetrical up and down. The mounting plate 15 is rotatably connected with the screw 16. The dual-axis motor 18 is fixedly connected between the upper and lower mounting plates 15. The output shaft of the dual-axis motor 18 is fixedly connected to the adjacent screw 16. The upper and lower guide rods 14 are slidably connected with the second slide 17. The second slide 17 is threadedly connected to the adjacent screw 16. The second slide 17 is sleeved on the coating plate 6. The second slide 17 is slidably connected to the left and right symmetrical scraper 19. The end of the scraper 19 close to the coating plate 6 is conical and fits the surface of the scraper 19. A front-to-back symmetrical second spring 20 is connected between the scraper 19 and the adjacent second slide 17.

[0028] When using this device, after the solder paste coating is completed, the staff drives the screw 16 to rotate through the dual-axis motor 18, and the rotation of the screw 16 drives the second slide 17 to slide backward, and the backward sliding of the second slide 17 drives the scraper 19 to move backward. The backward movement of the scraper 19 can scrape off the residual solder paste on the coating plate 6, and under the action of the expansion and contraction of the second spring 20, the scraper 19 will also move left and right to fit the coating plate 6, thereby ensuring the cleaning effect.
