Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, specifically to a continuous adhesive application device. Background Technology

[0002] Currently, in the early stages of computer screen assembly, most use adhesive application equipment to continuously adhere optical adhesive to the screen surface through automated technology. This improves the optical performance of the display, making the image clearer and more vibrant, and reducing visual interference caused by light reflection and refraction.

[0003] Most adhesive application equipment uses electric push rods to roll the optical adhesive onto the computer screen surface, thus applying the optical adhesive to the computer screen surface. Existing computer screens are usually thin, and if the rolling pressure of the pressure roller is too high, it can easily damage the computer screen. If the rolling pressure of the pressure roller is too low, it can easily lead to poor adhesion, thus affecting the adhesive application effect on the computer screen.

[0004] Based on this, the present invention designs a continuous adhesive application device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a continuous adhesive application device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A continuous adhesive applicator includes an adhesive applicator with an electric push rod fixedly connected to its inner top wall. It also includes a rolling mechanism, which comprises a slide cylinder fixedly connected to the telescopic end of the electric push rod. A bracket is slidably connected to the inner wall of the slide cylinder, and two rollers are rotatably connected to the inner wall of the bracket. A storage cylinder is fixedly connected to the inner top wall of the adhesive applicator, and the slide cylinder and storage cylinder are in communication. Both the slide cylinder and the storage cylinder store hydraulic oil. A moving rod is slidably connected to the inner wall of the storage cylinder, and a marking block is fixedly connected to the surface of the storage cylinder. A scraper is slidably connected to the inner wall of the bracket.

[0008] Furthermore, a first spring is fixedly connected to the opposite end of the slide cylinder and the bracket.

[0009] Furthermore, a second spring is fixedly connected to the inner top wall of the storage cylinder, and the bottom end of the second spring is fixedly connected to the end of the moving rod.

[0010] Furthermore, the bottom of the scraper forms an angle with the horizontal plane, and the bottom of the scraper is curved into an arc shape.

[0011] Furthermore, both the upper end of the inner wall of the slide cylinder and the lower end of the inner wall of the storage cylinder are fixedly connected to a stop block.

[0012] Furthermore, a fixed frame is fixedly connected to the surface of the electric push rod, and the surface of the bracket is slidably connected to the inner wall of the fixed frame.

[0013] Furthermore, the inner wall of the bracket is slidably connected to an elongated block, the surface of which is engaged with the inner wall of the scraper.

[0014] Furthermore, the surfaces of the rollers, scrapers, and long blocks are all made of silicone.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] 1. By cooperating with the slide cylinder, storage cylinder, moving rod and marking block, the roller and scraper are pressed evenly on the surface of the optical adhesive and the computer screen, avoiding damage to the computer screen, thus making the optical adhesive firmly adhere to the surface of the computer screen. The scraper is used to evenly scrape and press the optical adhesive, making the optical adhesive adhere smoothly to the surface of the computer screen, avoiding air bubbles at the adhesion point between the optical adhesive and the computer screen, thus ensuring the adhesive effect on the computer screen.

[0017] 2. The bottom of the scraper is curved into an arc shape and forms an angle with the horizontal plane, which ensures a large contact area with the optical adhesive and the computer screen surface. The bottom of the scraper is relatively smooth, which reduces damage to the computer screen and optical adhesive, achieves uniform scraping pressure over a large area, reduces the situation of excessive or insufficient local pressure, and improves the overall bonding quality.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0027] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A continuous adhesive applicator includes an adhesive applicator 100, an electric push rod 200 fixedly connected to the inner top wall of the adhesive applicator 100, and a rolling mechanism 300. The rolling mechanism 300 includes a slide cylinder 301 fixedly connected to the telescopic end of the electric push rod 200. A bracket 302 is slidably connected to the inner wall of the slide cylinder 301. Two rollers 303 are rotatably connected to the inner wall of the bracket 302. A storage cylinder 304 is fixedly connected to the inner top wall of the adhesive applicator 100. The slide cylinder 301 and the storage cylinder 304 are connected in communication. Both the slide cylinder 301 and the storage cylinder 304 store hydraulic oil. A moving rod 305 is slidably connected to the inner wall of the storage cylinder 304. A marking block 306 is fixedly connected to the surface of the storage cylinder 304. A scraper 307 is slidably connected to the inner wall of the bracket 302.

[0028] The slide cylinder 301 and the storage cylinder 304 are connected by a corrugated pipe. The bracket 302 and the moving rod 305 are both polyurethane rubber components, which have good elasticity and sealing performance, ensuring that the moving rod 305 is tightly attached to the inner wall of the storage cylinder 304 and the bracket 302 is tightly attached to the inner wall of the slide cylinder 301.

[0029] The adhesive applicator 100 typically consists of a feeding mechanism, an electric push rod 200, a rolling mechanism 300, a transmission mechanism, a PLC touch screen, a receiving mechanism, and a vision positioning mechanism. These are common and well-known technologies in the field and are not closely related to the technical issues of this application. Therefore, no detailed description has been provided.

[0030] In this embodiment of the invention, when applying adhesive to a computer screen, a suitable optical adhesive is selected based on the screen's size and shape, and then installed on the feeding mechanism of the adhesive applicator 100. Simultaneously, the quality and adhesion of the optical adhesive are checked to ensure it meets the bonding requirements. Based on the computer screen's specifications and bonding requirements, parameters of the adhesive applicator 100, such as bonding speed and temperature, are set. Through trial bonding operations, the equipment is adjusted and optimized to ensure the best bonding effect.

[0031] The cleaned computer screen is precisely placed on the transmission mechanism of the adhesive applicator 100. The conveyor belt on the transmission mechanism transports the computer screen, and the feeding mechanism starts to release optical adhesive, moving it to the bonding position according to the set speed and tension.

[0032] When the optical adhesive reaches the bonding position, manually activate the electric push rod 200. The telescopic end of the electric push rod 200 moves downward, causing the slide cylinder 301, bracket 302, roller 303, and scraper 307 to move downward, rolling the optical adhesive onto the computer screen surface. At this time, the telescopic end of the electric push rod 200 continues to move downward, causing the slide cylinder 301 to move downward on the surface of the bracket 302, so that some hydraulic oil inside the slide cylinder 301 is delivered to the storage cylinder 304. Excess hydraulic oil in the storage cylinder 304 pushes the moving rod 305 upward. When the end of the moving rod 305 touches the bottom of the marker block 306, manually close the electric push rod 200, so that the roller 303 and scraper 307 press evenly on the optical adhesive and the computer screen surface. The scraper 307 scrapes and presses the optical adhesive evenly, eliminating air bubbles between the optical adhesive and the computer screen, so that the optical adhesive and the computer screen are flat and bonded. The roller 303 rolls and presses the optical adhesive and the screen evenly, so that the optical adhesive and the screen are tightly bonded.

[0033] After bonding is completed, the bonding quality is inspected. The inspection includes checking whether the optical adhesive is fully bonded and whether there are defects such as bubbles, wrinkles, or curling edges.

[0034] After the bonding inspection is passed, the receiving mechanism collects and sorts the waste materials generated during the bonding process, such as release paper. At the same time, the bonded computer screens are removed from the conveyor belt for subsequent packaging and storage.

[0035] In this embodiment of the utility model, the sliding cylinder 301, storage cylinder 304, moving rod 305 and marking block 306 cooperate with each other to achieve the balance of pressure between the roller 303 and scraper 307 on the surface of the optical adhesive and the computer screen, avoiding damage to the computer screen, thereby making the optical adhesive firmly adhere to the surface of the computer screen. The scraper 307 evenly scrapes and presses the optical adhesive, making the optical adhesive adhere smoothly to the surface of the computer screen, avoiding air bubbles at the adhesion point between the optical adhesive and the computer screen, thus ensuring the adhesive effect on the computer screen.

[0036] In some embodiments, such as Figure 2-3As shown, in a preferred embodiment of this utility model, a first spring 308 is fixedly connected to the opposite ends of the slide cylinder 301 and the support 302, a second spring 309 is fixedly connected to the inner top wall of the storage cylinder 304, the bottom end of the second spring 309 is fixedly connected to the end of the moving rod 305, and a stop block 310 is fixedly connected to the upper end of the inner wall of the slide cylinder 301 and the lower end of the inner wall of the storage cylinder 304, a fixing frame 312 is fixedly connected to the surface of the electric push rod 200, and the surface of the support 302 is slidably connected to the inner wall of the fixing frame 312. The slide cylinder 301, the storage cylinder 304, the first spring 308, the second spring 309, and the stop block 310 are all stainless steel components.

[0037] In this embodiment of the utility model, the upward movement of the telescopic end of the electric push rod 200 causes the slide cylinder 301, the bracket 302, the roller 303 and the scraper 307 to move upward a certain height. The elastic force of the first spring 308 pushes the bracket 302 downward, and the elastic force of the second spring 309 pushes the moving rod 305 downward, so that the hydraulic oil in the storage cylinder 304 flows back into the slide cylinder 301, ensuring that the roller 303 and the scraper 307 can press evenly on the optical adhesive and the computer screen next time.

[0038] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the bottom of the scraper 307 forms an angle with the horizontal plane, the bottom of the scraper 307 is curved into an arc shape, and a long block 311 is slidably connected to the inner wall of the bracket 302. The surface of the long block 311 is engaged with the inner wall of the scraper 307. The surfaces of the roller 303, the scraper 307 and the long block 311 are all silicone components.

[0039] In this embodiment of the invention, the roller 303 and scraper 307 of the silicone component flexibly abut against the surface of the optical adhesive and the computer screen, reducing damage to the optical adhesive and the computer screen.

[0040] The scraper 307, with its curved bottom forming an angle with the horizontal plane, ensures a large contact area with the optical adhesive and the computer screen surface. The smooth bottom of the scraper 307 reduces damage to the computer screen and optical adhesive, achieves uniform scraping over a large area, reduces local pressure that is too high or too low, and improves the overall bonding quality.

[0041] The elongated block 311 facilitates the replacement of different sized scrapers 307, ensuring effective scraping of optical adhesive and computer screens.

[0042] It should be noted that the adhesive applicator 100 and electric push rod 200 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the adhesive applicator 100 and electric push rod 200 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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 will 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.
