Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A glue application mechanism includes: a base plate 1, on which a bracket 2 is fixedly mounted; a glue dispensing mechanism installed on the side of the bracket 2 for uniformly applying glue; and a glue application mechanism installed on the side of the bracket 2, with the glue dispensing mechanism located on one side of the glue application mechanism for receiving glue from the glue dispensing mechanism and applying glue.

[0028] It should be noted that this equipment is installed below the conveyor equipment and automatically applies adhesive as the screen is conveyed through the equipment.

[0029] In an optional embodiment: such as Figure 1 and Figure 2 As shown, the glue dispensing mechanism includes a glue dispensing valve 5, a glue dispensing pipe 6, a mounting bracket 18, a glue storage tank 19, and a glue quantity regulating valve 20;

[0030] Mounting bracket 18 is fixedly installed on the side of bracket 2, glue tank 19 is fixedly installed inside mounting bracket 18, glue quantity regulating valve 20 is fixedly installed on the top of bracket 2, glue dispensing valve 5 is fixedly installed on the side of bracket 2, glue tank 19 is connected to the inlet of glue quantity regulating valve 20 through glue delivery pipe 8, glue quantity regulating valve 20 is connected to the inlet of glue dispensing valve 5 through glue delivery pipe 8, and glue outlet pipe 6 is fixedly installed on the glue outlet of glue dispensing valve 5.

[0031] The interior of the glue storage tank 19 is sealed with a sealing cover 11, and an air inlet hose is connected to the sealing cover 11.

[0032] It should be noted that by opening the sealing cap 11, UV glue can be poured into the glue storage tank 19. After pouring the UV glue into the glue storage tank 19, the sealing cap 11 is installed inside the glue storage tank 19 to seal the glue storage tank 19. The air inlet hose is connected to an external air supply device, which supplies air into the inside of the glue storage tank 19 through the air inlet hose to increase the pressure inside the glue storage tank 19. The air pressure difference steadily pressurizes the UV glue in the glue storage tank 19 to the glue quantity regulating valve 20. The glue quantity regulating valve 20 controls the glue dispensing amount of the dispensing valve 5. After the UV glue is delivered to the dispensing valve 5 through the glue delivery pipe 8, the controlled UV glue flows onto the glue strip 9 through the glue dispensing pipe 6.

[0033] In an optional embodiment: such as Figure 3 and Figure 4 As shown, it also includes an angle transformation adjustment mechanism 7, which includes a first drive motor 71, an arc frame 72, a drive gear 74 and a support wheel 75.

[0034] The first drive motor 71 is fixedly installed on the side of the bracket 2, the drive gear 74 is fixedly installed on the output shaft of the first drive motor 71, the support wheel 75 is rotatably installed on the side of the bracket 2, the arc frame 72 has an integrally formed anti-detachment protrusion 73, the support wheel 75 has a positioning groove 76 for positioning the arc frame 72, the anti-detachment protrusion 73 is located in the positioning groove 76, the side of the arc frame 72 has multiple sets of teeth, and the drive gear 74 meshes with the teeth on the arc frame 72.

[0035] It should be noted that by cooperating with the first drive motor 71, the arc frame 72, the drive gear 74 and the support wheel 75, the position of the guide wheel 4 on the arc frame 72 can be adjusted. When adjusting the arc frame 72, the adhesive strip 9 can be adjusted to ensure that the adhesive can perfectly fit the glass edge contour of the display screen.

[0036] Specifically, the first drive motor 71 is started, and the output shaft of the first drive motor 71 drives the drive gear 74 to rotate. When the drive gear 74 rotates, the transmission arc frame 72 moves on the support wheel 75, thereby completing the adjustment of the adhesive strip 9.

[0037] The first drive motor 71 is configured as a motor with a brake. After the first drive motor 71 is de-energized, the arc frame 72 is subjected to force to prevent the drive gear 74 from rotating and affecting the operation.

[0038] In an optional embodiment: such as Figures 1 to 3 As shown, the glue application mechanism includes a glue strip drive wheel 3, a guide wheel 4, a glue application strip 9, and a second drive motor 10;

[0039] The second drive motor 10 is fixedly installed on the side of the bracket 2. The adhesive strip drive wheel 3 is fixedly installed on the output shaft of the second drive motor 10. There are multiple sets of guide wheels 4, of which three sets of guide wheels 4 are rotatably installed on the side of the bracket 2, and two sets of guide wheels 4 are rotatably installed on the arc frame 72. The adhesive strip 9 is provided on the multiple sets of guide wheels 4 and the adhesive strip drive wheel 3. The adhesive outlet tube 6 is bent, and one end of the adhesive outlet tube 6 is in contact with the adhesive strip 9.

[0040] It should be noted that the adhesive strip drive wheel 3, guide wheel 4, adhesive strip 9 and second drive motor 10 work together to rotate the adhesive strip 9, so that the adhesive strip 9 coated with UV glue is close to the display screen and the UV glue is applied to the glass of the display screen.

[0041] In an optional embodiment: such as Figure 3 As shown, it also includes a first scraper 13 and a second scraper 14 fixedly installed on the side of the bracket 2 for scraping off excess glue from the glue strip 9. The top of the first scraper 13 and the bottom of the second scraper 14 are both provided with semi-circular scraping grooves, and the glue strip 9 is disposed in the semi-circular scraping grooves.

[0042] It should be noted that, through the cooperation of the first scraper 13 and the second scraper 14, when the adhesive strip 9 passes through the first scraper 13 and the second scraper 14, the excess adhesive on the adhesive strip 9 is scraped off by the semi-circular scraping groove on the arc plate 12 and the second scraper 14.

[0043] In an optional embodiment: such as Figure 1 and Figure 2 As shown, it also includes an arc-shaped plate 12 fixedly installed on the side of the bracket 2. The arc-shaped plate 12 is inclined and located below the first scraper 13 and the second scraper 14.

[0045] It should be noted that, due to the setting of the arc plate 12, the excess glue scraped off the glue strip 9 falls onto the arc plate 12, flows along the arc plate 12, and is collected in the recycling glue box 15 through the discharge port 17.

[0046] The usage process of this utility model is as follows: Start the second drive motor 10. The output shaft of the second drive motor 10 drives the adhesive strip drive wheel 3 to rotate. The rotation of the adhesive strip drive wheel 3, in conjunction with the guide wheel 4, drives the adhesive strip 9 to rotate.

[0047] The air supply equipment delivers air into the glue storage tank 19 through the air inlet hose, increasing the pressure inside the glue storage tank 19. The air pressure difference steadily pressurizes the UV glue in the glue storage tank 19 to the glue quantity regulating valve 20. The glue quantity regulating valve 20 controls the glue dispensing amount of the dispensing valve 5. After the UV glue is delivered to the dispensing valve 5 through the glue delivery pipe 8, the UV glue flows onto the glue application strip 9 through the glue outlet pipe 6. The glue application strip 9 is rotated by the glue strip drive wheel 3 and guide wheel 4, thereby evenly dispensing the UV glue onto the glass edge of the display screen to achieve the purpose of glue edge sealing. Excess glue is scraped off by the first glue scraper 13 and the second glue scraper 14 below. The glue flows into the glue recycling box 15 through the arc plate 12. The recycled glue can be reused.

[0048] The control method in this application is automatic control through a programmable logic controller (PLC). The control circuit of the PLC can be easily implemented by those skilled in the art through simple programming, and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so the control method and circuit connection will not be explained in detail here. The device is powered by a built-in power supply or an external power supply.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
