Description

Technical Field

[0001] This utility model relates to the field of needle-based adhesive application technology, and more particularly to an adhesive application device. Background Technology

[0002] In modern manufacturing, especially in high-precision fields such as electronics, semiconductors, precision instruments and LED technology, dispensing plays a crucial role. As a key piece of equipment on automated production lines, the stability and accuracy of dispensing machines directly affect product quality and production efficiency. However, during the dispensing process, the cleanliness of the needle, as the part that directly contacts the adhesive, directly affects the coating effect of the adhesive and the final quality of the product.

[0003] Traditionally, needle cleaning has relied on manual operation. The operator holds the first side of a lint-free cloth and uses the second side (the side not in direct contact with the hand) to clean the dispensing needle – a very simple process. However, this method has a significant drawback: once the operator holds the first side of the lint-free cloth, contaminants from their hand quickly transfer to that side, rendering it unusable for cleaning and resulting in low utilization of the lint-free cloth.

[0004] Therefore, improvements to existing technologies are necessary.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figures 1-3This utility model designs a glue-wiping device, which includes a fixed plate 1, a feeding roller 2, a first conveying roller 7, a flipping assembly, a take-up roller 13, and a glue-wiping block with a receiving space. The feeding roller 2, the first conveying roller 7, and the take-up roller 13 are all rotatably connected to the fixed plate 1. A lint-free cloth 6 is wound on the feeding roller 2. The feeding roller 2 and the take-up roller 13 are provided on one side of the glue-wiping block, and the first conveying roller 7 and the flipping assembly are provided on the other side of the glue-wiping block. The needle assembly is located in the receiving space. The flipping assembly is used to receive the lint-free cloth 6 transmitted by the first conveying roller 7 and flip it 180 degrees. The feeding roller 2 and the first conveying roller 7 cooperate to allow the lint-free cloth 6 to pass through the receiving space and to wipe one side of the needle assembly with the first side of the lint-free cloth 6. The flipping assembly and the take-up roller 13 cooperate to allow the lint-free cloth 6 to pass through the receiving space and to wipe the other side of the needle assembly with the second side of the lint-free cloth 6.

[0032] It should be noted that neither the first nor the second side of the cleanroom cloth 6 of this invention comes into contact with human hands and is therefore uncontaminated. The cleanroom cloth 6, starting from the feeding roller 2, is guided by the first conveying roller 7 and enters the receiving space of the wiping block. At this point, the first side of the cleanroom cloth 6 contacts and wipes one side of the needle assembly. After wiping, the cleanroom cloth 6 continues to be conveyed to the flipping assembly, where it is flipped 180 degrees. The flipped cleanroom cloth 6 is then guided by the second conveying roller 11 and re-enters the receiving space of the wiping block. At this point, the second side of the cleanroom cloth 6 contacts and wipes the other side of the needle assembly. Finally, the wiped cleanroom cloth 6 is conveyed to the winding roller 13 for winding. The flipping assembly achieves automatic flipping of the cleanroom cloth 6, ensuring that both sides of the cleanroom cloth 6 are fully utilized.

[0033] Specifically, the adhesive application device also includes a first tensioning component, which is located between the feeding roller 2 and the adhesive application block and is rotatably connected to the fixed plate 1.

[0034] Specifically, the first tensioning assembly includes two first tensioning rollers 3, which are arranged in an alternating manner. The two alternating first tensioning rollers 3 can effectively control the tension of the cleanroom cloth 6 between the feed roller 2 and the wiping block, ensuring that the cleanroom cloth 6 remains stable during transmission and avoiding deviation or wrinkles caused by uneven tension.

[0035] Specifically, the adhesive application device also includes a second tension roller 8, which is located between the first conveyor roller 7 and the flipping assembly, and is rotatably connected to the fixed plate 1. The second tension roller 8 of this invention helps maintain the flatness of the lint-free cloth 6, laying a good foundation for subsequent flipping and wiping operations.

[0036] Specifically, the flipping assembly includes a first flipping block 9 and a second flipping block 10 arranged at intervals. The first flipping block 9 has a first notch, and the second flipping block 10 has a second notch. The first notch and the second notch are arranged facing each other. The first notch is close to the second tensioning roller 8 and is inclined in the northeast direction, and the second notch is close to the second conveying roller 11 and is inclined in the northwest direction.

[0037] When the cleanroom cloth 6 of this invention passes through the first notch and the second notch, it will be guided and constrained by the first notch and the second notch, thus causing it to flip over.

[0038] Specifically, the adhesive application device also includes a third tensioning assembly, which is located between the take-up roller 13 and the adhesive application block, and includes two third tensioning rollers 12, which are staggered. The two staggered third tensioning rollers 12 also play a role in controlling the tension, avoiding loosening or tangling problems that may occur during the take-up process.

[0039] Specifically, the adhesive application device also includes a first motor 15 and a second motor 16. The first motor 15 is connected to the feeding roller 2, and the second motor 16 is connected to the take-up roller 13. The addition of the first motor 15 and the second motor 16 enables automatic driving of the feeding roller 2 and the take-up roller 13, further improving the automation level of the device.

[0040] Specifically, the adhesive application device also includes a bidirectional threaded rod, a fixed plate 1 connected to a guide rail 14, and an adhesive application block including a first clamping block 4 and a second clamping block 5, both of which are mounted on the guide rail 14. The first threaded end of the bidirectional threaded rod is threaded to the first clamping block 4, and the second threaded end of the bidirectional threaded rod is threaded to the second clamping block 5, to adjust the accommodating space. The combined use of the bidirectional threaded rod and the guide rail 14 allows for easy adjustment of the distance between the first clamping block 4 and the second clamping block 5 in the adhesive application block, thereby accommodating the application of needles of different sizes.

[0041] Specifically, the adhesive application device also includes a telescopic rod and several grippers, the needle assembly includes several needles, the fixing plate 1 has an opening corresponding to the location of the accommodating space, the telescopic rod is located below the opening, the several grippers are connected to the telescopic end of the telescopic rod and clamp the needles, and the arrangement direction of the several needles is parallel to the moving direction of the cleanroom cloth 6.

[0042] The gripper of this invention can firmly hold the needle, ensuring that the needle will not shake or fall off during the wiping process, thereby improving the stability and effect of wiping. The telescopic rod can drive the needle through the opening to the receiving space.

[0043] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
