Description

Technical Field

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

[0002] For the production of electronic and electromechanical products, adhesive application equipment is not only a fundamental process tool but also an indispensable key link in ensuring product quality, improving production efficiency, and achieving automated production. In devices such as smartphones and tablets, components like camera modules, displays, batteries, and sensors require precise dispensing technology for secure bonding to ensure these components do not loosen or detach during use. Critical components such as motor windings, relay coils, and connector terminals also need to be fixed with adhesive to prevent displacement or damage in vibrating environments. Different adhesives have different viscosities and curing characteristics, requiring specially designed nozzles to ensure optimal dispensing results. Depending on the specific application requirements, dispensing patterns may be needed, such as dotted, linear, or surface application. For example, precise dispensing on tiny components in electronic products requires nozzles with small orifices; while for larger-area applications, fan-shaped or wide-mouth nozzles are needed. By selecting appropriate nozzle size and shape, the accuracy of adhesive application can be significantly improved.

[0003] When using an adhesive applicator, different adhesive nozzles need to be changed for different types of products. However, changing the adhesive nozzles of existing adhesive applicators is very inconvenient, making it difficult to adapt to different adhesive application needs. Therefore, an adhesive applicator is provided. Utility Model Content

[0004] The main objective of this invention is to provide an adhesive application device to solve the problems raised in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a glue application device is provided, including a base plate, a rotating shaft rotatably mounted on one side of the base plate, a connecting rod slidably mounted inside the rotating shaft, and further including: a glue feeding part rotatably mounted on one end of the connecting rod; and a replacement part fixedly mounted on the lower end of the glue feeding part, the replacement part including a replacement rotating shaft, a plurality of nozzles fixedly mounted inside the replacement rotating shaft, and different nozzles being used by rotating the replacement rotating shaft.

[0006] Furthermore, a height adjustment groove is provided inside the rotating shaft, and one end of the connecting rod is slidably installed in the height adjustment groove. The connecting rod has an L-shaped structure.

[0007] Furthermore, the glue feeding part includes an angle adjusting block, one end of which is rotatably installed inside the connecting rod, and the other end of which is fixedly installed with a glue feeding tube.

[0008] Furthermore, the angle adjustment block includes a rotating shaft, one end of which passes through the connecting rod and is exposed to the outside. A mounting plate is fixedly installed on one end of the rotating shaft. The side wall of the mounting plate has several fixing screw holes arranged in a ring array, and fixing bolts are installed in the internal threads of the fixing screw holes.

[0009] Furthermore, the replacement part includes a mounting block, which is fixedly mounted on one side of the glue delivery tube, and an adjusting shaft is rotatably mounted inside the mounting block.

[0010] Furthermore, a telescopic groove is provided on the lower surface of the adjusting shaft, and a telescopic block is slidably installed in the telescopic groove. A spring is fixedly installed on one side of the telescopic block, and the other end of the spring is fixedly installed in the telescopic groove.

[0011] Furthermore, the replacement shaft is fixedly installed at the lower end of the telescopic block. The surface of the replacement shaft has several insertion holes arranged in a circular array. The nozzle is fixedly installed at the lower end of the insertion holes. One end of the glue delivery tube is inserted into the insertion hole. The side wall of the replacement shaft has several positioning screw holes that connect to the insertion holes. Positioning bolts are installed in the internal threads of the positioning screw holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a cylinder to push a connecting rod that slides up and down within a height adjustment groove. The connecting rod has an L-shaped structure, and its horizontal section drives the entire glue delivery section to rise and fall vertically, thus accommodating glue delivery tubes of different lengths and ensuring the optimal distance between the nozzle and the coating surface. Rotating the mounting plate causes the angle adjustment block to rotate along the rotating shaft, thereby changing the angle of the glue delivery tube. After adjusting to the desired angle, tightening the fixing bolts on the mounting plate locks the angle, allowing the glue delivery tube to flexibly adapt to inclined and vertical glue application requirements. When changing the nozzle, manually pull down the replacement shaft and rotate it. The insertion hole rotates accordingly, aligning the next required nozzle with the glue delivery tube outlet. After releasing, the spring returns to its original position, and the glue delivery tube is inserted into the insertion hole. Tightening the positioning bolt in the positioning screw hole secures the side wall of the glue delivery tube, fixing the position of the replacement shaft and ensuring stability and reliability. By sliding the connecting rod within the height adjustment groove, it can adapt to electronic products of different heights. There is no need to disassemble the glue delivery tube; simply rotating the replacement shaft is sufficient to change different nozzles, reducing replacement time. The entire process requires no disassembly of the pipe or the use of tools, enabling rapid nozzle change. Attached Figure Description

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] This embodiment provides a glue application device, including a base plate 1, a rotating shaft 11 rotatably mounted on one side of the base plate 1, a connecting rod 12 slidably mounted inside the rotating shaft 11, and also includes: a glue feeding part 2, which is rotatably mounted on one end of the connecting rod 12; and a replacement part 3, which is fixedly mounted on the lower end of the glue feeding part 2. The replacement part 3 includes a replacement rotating shaft 34, and a plurality of nozzles 342 are fixedly mounted inside the replacement rotating shaft 34. Rotating the replacement rotating shaft 34 allows for the use of different nozzles 342.

[0024] like Figure 1 , Figure 2 As shown, a height adjustment groove 111 is provided inside the rotating shaft 11. One end of the connecting rod 12 is slidably installed in the height adjustment groove 111. The connecting rod 12 has an L-shaped structure. A cylinder is fixedly installed at the bottom of the height adjustment groove 111. The piston rod of the cylinder is fixedly installed at the lower end of the connecting rod 12. The cylinder pushes the connecting rod 12 to slide up and down in the height adjustment groove 111. The connecting rod 12 has an L-shaped structure. Its horizontal section drives the entire glue feeding part 2 to achieve vertical lifting and lowering, thereby adapting to glue feeding tubes 22 of different lengths and ensuring that the nozzle 342 maintains the optimal distance from the glue coating surface.

[0025] like Figure 2 , Figure 3 As shown, the glue feeding part 2 includes an angle adjustment block 21. One end of the angle adjustment block 21 is rotatably mounted on the end of the connecting rod 12, and the other end of the angle adjustment block 21 is fixedly mounted with a glue feeding tube 22.

[0026] like Figure 3As shown, the angle adjustment block 21 includes a rotating shaft. One end of the rotating shaft passes through the connecting rod 12 and is exposed to the outside. A mounting plate 211 is fixedly installed on one end of the rotating shaft. The side wall of the mounting plate 211 has a number of fixing screw holes 212 arranged in a ring. Fixing bolts are installed in the internal threads of the fixing screw holes 212. Rotating the mounting plate 211 causes the angle adjustment block 21 to rotate along the rotating shaft, thereby changing the angle of the glue delivery tube 22. After adjusting to the required angle, the fixing bolts on the mounting plate 211 are tightened. The fixing bolts press against the side wall of the connecting rod 12 to lock the angle, so that the glue delivery tube 22 can flexibly adapt to the needs of inclined and vertical glue application.

[0027] like Figure 4 As shown, the replacement unit 3 includes a mounting block 31, which is fixedly installed on one side of the glue delivery tube 22, and an adjusting shaft 32 is rotatably installed inside the mounting block 31.

[0028] like Figure 4 As shown, a telescopic groove 321 is provided on the lower surface of the adjusting shaft 32. A telescopic block 33 is slidably installed in the telescopic groove 321. A spring 331 is fixedly installed on one side of the telescopic block 33, and the other end of the spring 331 is fixedly installed in the telescopic groove 321.

[0029] like Figure 4 As shown, the replacement shaft 34 is fixedly installed at the lower end of the telescopic block 33. The surface of the replacement shaft 34 has several insertion holes 341 arranged in a circular array. The nozzle 342 is fixedly installed at the lower end of the insertion holes 341. One end of the glue delivery tube 22 is inserted into the insertion hole 341. The side wall of the replacement shaft 34 has several positioning screw holes 343 communicating with the insertion holes 341. Positioning bolts are installed in the internal threads of the positioning screw holes 343. When replacing the nozzle 342, the replacement shaft 34 is manually pulled downwards and then rotated. 41 rotates to align the next required nozzle 342 with the outlet of the dispensing tube 22. After releasing, the spring 331 returns to its original position, and the dispensing tube 22 is inserted into the insertion hole 341. Tighten the positioning bolt in the positioning screw hole 343. The positioning bolt presses against the side wall of the dispensing tube 22, fixing the position of the replacement shaft 34 to ensure stability and reliability. There is no need to disassemble the dispensing tube 22. Only the replacement shaft 34 needs to be rotated to change to a different nozzle 342, reducing replacement time. The whole process does not require disassembling the pipe or using tools, achieving quick nozzle change.

[0030] In practical use, this invention uses a cylinder to push the connecting rod 12 to slide up and down within the height adjustment groove 111. The connecting rod 12 has an L-shaped structure, and its horizontal section drives the entire glue delivery section 2 to achieve vertical lifting and lowering, thereby adapting to glue delivery tubes 22 of different lengths and ensuring that the nozzle 342 maintains the optimal distance from the coating surface. Rotating the mounting plate 211 causes the angle adjustment block 21 to rotate along the rotation axis, thereby changing the angle of the glue delivery tube 22. After adjusting to the required angle, tightening the fixing bolts on the mounting plate 211 locks the angle, allowing the glue delivery tube 22 to flexibly adapt to inclined and vertical glue application requirements. When replacing the nozzle 342, manually pull down the replacement shaft. After rotating the shaft 34, the insertion hole 341 rotates accordingly, aligning the next required nozzle 342 with the outlet of the glue delivery tube 22. After releasing, the spring 331 returns to its original position, and the glue delivery tube 22 is inserted into the insertion hole 341. Tighten the positioning bolt in the positioning screw hole 343. The positioning bolt presses against the side wall of the glue delivery tube 22, fixing the position of the shaft 34 to ensure stability and reliability. The shaft slides in the height adjustment groove 111 via the connecting rod 12 to adapt to electronic products of different heights. There is no need to disassemble the glue delivery tube 22; simply rotating the shaft 34 is sufficient to change to a different nozzle 342, reducing replacement time. The entire process does not require disassembling pipes or using tools, achieving rapid nozzle change.
