[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, a PU glue coating device for a glass cover plate includes a PU glue coating device body 1, a work station 2 is fixedly installed on the middle part of the upper side of the PU glue coating device body 1, a U-shaped plate 4 is fixedly connected to the upper side of the PU glue coating device body 1, a threaded shaft 5 is rotatably connected to the inner side of the U-shaped plate 4, a lifting block 6 is threadedly connected to the outer surface of the threaded shaft 5, and a fixed plate 7 is connected to the front side of the lifting block 6;

[0028] Two symmetrically arranged U-shaped mounting seats 8 are installed on the front side of the fixed plate 7, and the wire mesh plate 9 is clamped on the front side of the two U-shaped mounting seats 8. The inner side surfaces of the two U-shaped mounting seats 8 are slidably connected with array-distributed positioning round rods 13, and a first connecting spring 14 is connected in an array between the positioning round rods 13 and the U-shaped mounting seats 8. The upper side of the positioning round rods 13 is fixedly connected to the top plate 15, and the front sides of the two U-shaped mounting seats 8 are rotatably connected with two limit rotating plates 16 for fixing the wire mesh plate 9.

[0029] An electric slide 10 is fixed on the front side of the fixed plate 7, and an electric slider 11 is installed on one side of the electric slide 10. A horizontal plate 12 is fixedly connected to the front side of the electric slider 11, and a cylinder 17 is fixed on the lower side of the horizontal plate 12. A base plate 18 is installed on the lower side of the cylinder 17, and a scraper 19 is fixedly connected to the lower side of the base plate 18. The PU glue smearing device can select three-layer scrapers of different hardness according to the smearing requirements. At this time, a three-layer scraper is produced, which is hard in the middle and soft on both sides. It is used for smearing and printing on glass cover plates, reducing the number of times the scraper is replaced. At the same time, it can be installed on the scraper 19 according to the size of the silk-screen pattern and the length of the three-layer scraper required for cutting. Then, the pressure and angle of the scraper 19 are adjusted to determine the smearing and printing parameters and improve the smearing effect.

[0030] The front side of the work station seat 2 is clamped with a tooling plate 3, and an adapter groove 333 is opened on the upper side of the tooling plate 3. The glass cover body 222 is clamped inside the adapter groove 333. The bottom end of the tooling plate 3 is slidably connected to the movable push plate 20. A second connecting spring 21 is fixedly connected between the movable push plate 20 and the tooling plate 3. The front side of the tooling plate 3 is clamped with an L-shaped positioning plug-in plate 22 for fixing the movable push plate 20. Through the setting of the L-shaped positioning plug-in plate 22, the movable push plate 20 is pressed downward, and then the L-shaped positioning plug-in plate 22 is clamped to the front of the movable push plate 20 for The elastic movable push plate 20 is positioned to facilitate the subsequent pushing out of the glass cover. The rear side of the L-shaped positioning plug plate 22 passes through the tooling plate 3 and extends to the front side of the movable push plate 20. Both ends of the tooling plate 3 are fixedly installed with reinforcing protrusions 23 for fixing the tooling plate 3. Through the setting of the reinforcing protrusions 23, the two reinforcing protrusions 23 can be used to drive the tooling plate 3 to be clamped and fixed to the inside of the work station seat 2, so that different tooling plates 3 can be quickly replaced for processing glass cover plates of different sizes. It is easy to use. U-shaped handles 24 are respectively installed on the front sides of the tooling plates 3.

[0031] A fixed block 27 is fixedly connected to the upper side of the top plate 15, and a support rotating plate 28 for supporting the top plate 15 is rotatably connected inside the fixed block 27. Through the setting of the support rotating plate 28, when the support rotating plate 28 is in a vertical state, it can be used to limit the two top plates 15, so that the elastic positioning round rod 13 can be away from the wire mesh plate 9 to facilitate the removal of the wire mesh plate 9.

[0032] The upper side of the threaded shaft 5 passes through the U-shaped plate 4 and extends to the upper side of the U-shaped plate 4. The servo motor 25 is fixedly installed on the upper side of the threaded shaft 5 through the motor mounting plate. The upper side of the positioning rod 13 passes through the U-shaped mounting seat 8 and extends to the upper side of the U-shaped mounting seat 8. The inner side surface of the U-shaped plate 4 is connected to two guide rods 26. The outer surfaces of the two guide rods 26 are slidably connected to the inner side of the lifting block 6. The two guide rods 26 can be used to guide the moving trajectory of the lifting block 6, so that the lifting block 6 can smoothly drive the silk screen plate 9 to move up and down, which is convenient for smearing and printing on the glass cover.

[0033] The upper side of the screen plate 9 is provided with an array of grooves 111 , which are matched with the positioning rods 13 . The lower side of the positioning rods 13 is snap-fitted to the upper side of the screen plate 9 through the grooves 111 .

[0034] The working principle of the PU glue coating device for glass cover provided by the utility model is as follows:

[0035] By clamping the screen plate 9 to the inside of the two U-shaped mounting seats 8, the two supporting rotating plates 28 are rotated respectively to release the limit of the two top plates 15, so that the two groups of positioning round rods 13 equipped with the first connecting springs 14 can automatically extend downward, so that the two groups of positioning round rods 13 with elastic force can be clamped into the grooves 111 of the screen plate 9 for preliminary clamping and fixing the screen plate 9, and then the two limiting rotating plates 16 are rotated in turn to the front of the screen plate 9 to squeeze the limiting screen plate 9 and ensure the stability of the screen plate 9. In this way, the plug-in method is used to facilitate the loading and unloading of the screen plate 9 and the replacement of the screen plate 9 with other patterns, which saves time and effort in operation, thereby improving the overall processing efficiency of the PU glue coating device. Then, the PU glue is sprayed onto the screen plate 9, and the cylinder 17 drives the scraper 19 to move to the inside of the screen plate 9. Then, the motor of the electric slide 10 is used to drive the electric slider 11 to move on the electric slide 10, so that the scraper 19 scrapes the PU glue onto the pattern of the screen plate 9, so that the pattern shape on the screen plate 9 is coated on the glass cover plate;

[0036] By placing the glass cover plate body 222 into the adapter groove 333 of the tooling plate 3, the glass cover plate body 222 is limited and fixed, so that the glass cover plate can be stably and reliably coated with PU glue, and then the output shaft of the servo motor 25 drives the threaded shaft 5 to rotate, so that the lifting block 6 on the threaded shaft 5 can move downward, so as to drive the screen plate 9 to fit above the glass cover plate body 222, so that the scraper 19 can be used to apply the pattern on the glass cover plate, and then the U-shaped mounting seat 8 is moved upward and away from the glass cover plate body 222 to complete the reset work, and then the L-shaped positioning plug 22 is pulled out, so that the limit of the movable push plate 20 equipped with the second connecting spring 21 can be released, so that the elastic force of the second connecting spring 21 can be used to allow the movable push plate 20 to automatically push out the glass cover plate body 222, thereby facilitating the removal of the glass cover plate after the pattern is applied.
