Description

Technical Field

[0001] This utility model relates to the field of adhesive stretching machines, and in particular to a COB LED strip adhesive stretching machine. Background Technology

[0002] COB LED strips, as a new type of linear lighting strip, have an exquisite appearance and offer advantages such as soft and uniform light, no light spots, multiple waterproof options, good heat dissipation, and a longer lifespan. They are the preferred lighting product for home lighting, outdoor lighting, and hotel lighting.

[0003] The production of COB LED strips requires encapsulating a chip onto a strip made of flexible printed circuit board (FPCB). Then, a layer of encapsulating adhesive mixed with phosphor is directly applied to the chip surface, thus forming the COB LED strip. To automate the production process and ensure dispensing accuracy, current COB LED strip manufacturing often employs a continuous dispensing method, where adhesive is continuously applied to the FPCB. However, existing methods typically use a belt conveyor to deliver the LED strip to the dispensing mechanism. The drawback of this approach is that inconsistent belt thickness or belt undulations during transport can cause uneven belt height, resulting in uneven adhesive distribution when the strip reaches the dispensing mechanism. This affects the dispensing effect, leading to unstable product quality, lower yield rates, and higher processing costs.

[0004] Therefore, it is necessary to improve the existing COB LED strip stretching machine. Utility Model Content

The adhesive pulling device includes a positioning frame, a conveying structure, and an adhesive pulling mechanism. The conveying structure is placed on the positioning frame, and the adhesive pulling mechanism includes an adhesive dispensing mechanism located above the conveying structure and an adhesive separating structure located in the middle section of the conveying structure.

[0008] The conveying structure includes a material conveying channel placed on the positioning frame, a transmission belt, and a moving component for conveying a drive light strip forward along the material conveying channel. The material conveying channel includes a first substrate and a second substrate, which are mounted one after the other on the positioning frame. The glue separation structure is disposed between the first substrate and the second substrate and is located on the same horizontal plane as the material conveying channel.

[0009] The moving component is disposed on the positioning frame. The moving component includes a drive motor and a conveyor roller group. The conveyor roller group is located below the glue separation structure. The transmission belt is wound around the first substrate, the conveyor roller group and the second substrate.

[0010] In some embodiments, the conveying roller group includes a first conveying roller, a second conveying roller, a third conveying roller, a fourth conveying roller, a fifth conveying roller, and a sixth conveying roller.

[0024] Figure 3 yes Figure 2 A three-dimensional schematic diagram of part A in the middle;

[0025] Figure 4 This is an exploded view of the adhesive-pulling device in the embodiment. Detailed Implementation

[0026] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0027] like Figures 1 to 4 As shown, this embodiment provides a COB LED strip adhesive pulling machine, including a frame 1, on which an adhesive pulling device 2 is provided. The adhesive pulling device 2 includes a positioning frame 3, a conveying structure 4, and an adhesive pulling mechanism 5. The conveying structure 4 is placed on the positioning frame 3. The adhesive pulling mechanism 5 includes an adhesive dispensing mechanism 51 located above the conveying structure 4 and an adhesive separating structure 52 located in the middle section of the conveying structure 4.

[0028] The conveying structure 4 includes a material conveying channel 6, a transmission belt 7, and a moving component 8 that drives the LED strip to move forward along the material conveying channel 6, all placed on the positioning frame 3. The material conveying channel 6 includes a first substrate 61 and a second substrate 62, which are mounted one after the other on the positioning frame 3. The adhesive dispensing structure 52 is located between the first substrate 61 and the second substrate 62 and is on the same horizontal plane as the material conveying channel 6. The adhesive dispensing structure 52 differs from the conventional design where a single belt transports the LED strip to the end. Instead, when the LED strip passes the adhesive-pulling mechanism 5, the transmission belt 7 moves under the adhesive dispensing structure 52. After the LED strip is dispensed, the transmission belt 7 returns to the surface and continues to transport it forward. This ensures that the LED strip is in a uniformly flat state during adhesive dispensing, preventing unevenness caused by inconsistent thickness of the transmission belt 7 or belt undulations and folds.

[0029] The moving component 8 is mounted on the positioning frame 3. The moving component 8 includes a drive motor 81 and a conveyor roller group 82. The conveyor roller group 82 is located below the glue-separating structure 52. The transmission belt 7 is wound around the first substrate 61, the conveyor roller group 82, and the second substrate 62. Because the belt cannot continuously move along the material conveying channel 6 due to the influence of the glue-separating structure 52, the design of the moving component 8 drives the transmission belt 7 to maintain cyclical movement.

[0030] Specifically, the conveyor roller assembly 82 includes a first conveyor roller 821, a second conveyor roller 822, a third conveyor roller 823, a fourth conveyor roller 824, a fifth conveyor roller 825, and a sixth conveyor roller 826. The positioning frame 3 has several positioning holes 31 facing corresponding positions. The ends of the first conveyor roller 821, the second conveyor roller 822, the third conveyor roller 823, the fourth conveyor roller 824, and the sixth conveyor roller 826 are rotatably connected to the positioning frame 3 through the positioning holes 31. This facilitates the movement of the transmission belt 7 through the conveyor roller assembly 8, and because the front and back sides contact different conveyor rollers during the conveying process, the transmission belt 7 can regain its flatness through movement when it becomes uneven or folded. The design of protective covers 32 on the outer side of the positioning frame 3 and on the ends of the conveyor rollers prevents workers from coming into contact with the conveyor rollers and getting injured.

[0031] Furthermore, the positioning frame 3 has a groove 33 on its outer side facing a corresponding position, and the end of the fifth conveying roller 825 can pass through the groove 33. A fixing seat 34 is provided in front of the groove 33, and the fixing seat 34 has a first bolt hole 341. The end of the fifth conveying roller 825 has a second bolt hole 8251 that cooperates with the first bolt hole 341. The second bolt hole 8251 is detachably connected to the first bolt hole 341 by a bolt. The end of the fifth conveying roller 825 can move along the groove 33, and the second bolt hole 8251 and the first bolt hole 341 can be detachably connected by a bolt, thereby adjusting the tension of the transmission belt 7.

[0032] Specifically, one side of the drive motor 81 is fixed to the positioning frame 3. The end of the second conveying roller 822 passes through the protective cover 32 and is connected to the first gear 8221. A second gear 811 is provided at the end of the drive motor 81. The first gear 8221 and the second gear 811 are connected by a transmission belt to form a belt drive system. The drive motor 81 drives the conveying roller group 82 to rotate through the belt drive system. Thus, multiple conveying rollers can be driven by one motor, which not only saves motors and reduces the production cost of this LED strip adhesive stretching machine, but also reduces the difficulty of daily maintenance.

[0033] Preferably, the first conveyor roller 821 is positioned below the end of the first substrate 61, the third conveyor roller 823 is positioned below the front end of the second substrate 62 with the first conveyor roller 821 and the third conveyor roller 823 at the same height, the second conveyor roller 822 is positioned below the adhesive separation structure 52 with a height lower than the first conveyor roller 821 and the third conveyor roller 823, the fourth conveyor roller 824 is positioned below and behind the third conveyor roller 823, the sixth conveyor roller 826 is positioned below and in front of the first conveyor roller 821 with the heights of the fourth conveyor roller 824 and the sixth conveyor roller 826 being the same as the height of the second conveyor roller 822, and the fifth conveyor roller 825 is positioned below the first conveyor roller 821 and the sixth conveyor roller 826 with a height lower than the sixth conveyor roller 826. This arrangement ensures a reasonable distribution of the conveyor rollers and prevents them from colliding with each other.

[0034] Furthermore, the drive belt 7 is placed on the material conveying channel 6, moving from the front end of the first substrate 61 to the end of the first substrate 61, sequentially passing through the first conveying roller 821, the second conveying roller 822, the third conveying roller 823, the second substrate 62, the fourth conveying roller 824, the fifth conveying roller 825, and the sixth conveying roller 826 before returning to the first substrate 61 in a cyclical motion. Both sides of the drive belt 7 can contact different conveying rollers during the movement. If the drive belt 7 has undulated or folded during the previous movement, it can become flat again during this process. At the same time, it facilitates the smooth feeding of the light strip into the adhesive separation structure 52, allowing it to seamlessly return to the drive belt 7 to continue moving forward.

[0035] Preferably, the adhesive dispensing structure 52 includes a positioning plate 521 and a pressing buffer device 522. The positioning plate 521 is made of rigid material and is fixedly installed between the first substrate 61 and the second substrate 62. Because the positioning plate 521 has a hollow design and is made of rigid material, it has good support and will not easily deform over long-term use, maintaining a smooth and flat surface for an extended period, thus achieving the technical effect of flat arrangement of the LED strips during adhesive dispensing.

[0036] The downward pressure buffer device 522 includes support seats 523 disposed at both ends of the positioning plate 521, and a support plate 524 fixedly disposed between the support seats 523. Two lifting devices 525 are fixedly disposed on the side of the support plate 524 facing the second substrate 62. A dispensing positioning grid plate 526 is connected below the lifting devices 525. A spring is provided inside the lifting device 525 to drive the dispensing positioning grid plate 526 to rise / fall. When the light strip enters the positioning plate 521, the lifting device 525 descends, causing the dispensing positioning grid plate 526 to gently press down on the light strip. The design of the downward pressure buffer device 522 mainly serves to flatten the light strip and provide a buffering effect. When the light strip enters the positioning plate 521, the lifting device 525 gently presses down on the light strip. If the thickness of the light strip is different, the lifting device 525 will rise and fall with the light strip, thereby gently pressing down on the light strip, achieving a flattening effect and making the dispensing more uniform.

[0037] Furthermore, the material conveying channel 6 also includes a pressing structure 63. The pressing structure 63 includes profiles 631 on both sides of the material conveying channel 6 and several roller seats 632 positioned opposite each other on the profiles 631. Several pressing rollers 633 are spaced across the material conveying channel 6 in the front-to-back direction on the profiles 631 for pressing the light strip. This not only helps maintain the light strip's flat alignment but also facilitates better adhesive distribution on the light strip after roller pressing.

[0038] Preferably, a visual detector 9 is provided on the front side of the adhesive dispensing structure 52. The visual detector 9 is used to acquire a visual image of the LED strip within the adhesive dispensing structure 52. This helps staff to promptly monitor the adhesive application status of the LED strip.

[0039] Preferably, the frame 1 is equipped with a control system, and the conveying structure 4, the adhesive application mechanism 5, and the vision detector 9 are electrically connected. This makes the design more automated and easier to operate, helping workers, especially newcomers, to quickly master the operation of this LED strip adhesive application machine.

[0040] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
