[0028] The following will further describe the present invention in detail in conjunction with the attached Figures 1-3 drawings.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] Embodiment 1: Refer to Figures 1-3 As shown in the figure, a screen glue injection device is shown, including a machine base 4. A conveying mechanism 1 for conveying the screen, a transfer mechanism 2 for transferring the screen, and a glue injection mechanism 3 for screen glue injection are arranged on the machine base 4. The conveying mechanism 1 and the glue injection mechanism 3 are arranged along the width direction of the machine base 4, and the transfer mechanism 2 is arranged between the conveying mechanism 1 and the glue injection mechanism 3.

[0031] In this embodiment, a glue injection station is arranged on the machine base 4. The glue injection mechanism 3 includes a loading component 31 and a glue injection component 32. The loading component 31 includes an upper mold base 311 suspended above the glue injection station, a lower mold base 312 that can be lifted and translated along a direction close to or away from the glue injection station, and a first driving module 315 for driving the movement of the lower mold base 312. Among them, the translation direction of the lower mold base 312 is the same as the width direction of the machine base 4. The first driving module 315 includes a cylinder for driving the lifting of the lower mold base 312 and a linear motor for driving the translation of the lower mold base 312. A first sliding seat 316 is carried at the bottom of the lower mold base 312, and the first sliding seat 316 is slidably connected to the above-mentioned linear motor. The cylinder is installed on the first sliding seat 316, and the piston rod of the cylinder is connected to the lower mold base 312.

[0032] A top die base 311 is provided with a top die groove 313 at the bottom, and a bottom die base 312 is provided with a bottom die groove 314 at the top. When the bottom die base 312 is located at the glue injection station, the projection of the top die groove 313 at the glue injection station coincides with the bottom die groove 314. The bottom die base 312 has a die closing position for docking with the top die base 311 during its movement stroke. The top die groove 313 and the bottom die groove 314 are correctly docked at the die closing position and enclose a die cavity. The glue injection assembly 32 is used to inject glue into the die cavity.

[0033] During glue injection, the conveying mechanism 1 and the transfer mechanism 2 cooperate with each other and transfer the carrier loaded with the screen into the bottom die groove 314. The bottom die base 312 drives the carrier to translate and lift and closes the die with the top die base 311. Subsequently, the glue injection of the screen can be completed through the glue injection assembly 32. There is no need to manually load the screen, which not only improves the glue injection efficiency, but also the correctly docked top die groove 313 and bottom die groove 314 can greatly improve the die closing accuracy, thereby improving the glue injection quality of the screen.

[0034] In this embodiment, the top die base 311 includes a receiving plate 3111, three die openings penetrating through the receiving plate 3111, and three templates 3112 respectively covering the three die openings. Each template 3112 and the corresponding die opening enclose a top die groove 313; there are three bottom die bases 312 and three first driving modules 315. The three bottom die bases 312 correspond to the three top die grooves 313 one by one. Each bottom die base 312 is driven by the corresponding first driving module 315 and docks with the corresponding top die groove 313. The three bottom die bases 312 and the corresponding three top die grooves 313 can simultaneously inject glue into three screens to improve the glue injection efficiency.

[0035] In this embodiment, the glue injection mechanism 3 further includes a vacuum assembly 33. The vacuum assembly 33 includes a vacuum pump 331 provided on the machine base 4 and a vacuum tube 332 connected to the vacuum pump 331. The vacuum tube 332 includes a main pipeline 3321 and three branch pipelines 3322 connected to the main pipeline 3321. The main pipeline 3321 is connected to the vacuum pump 331. The three branch pipelines 3322 are respectively connected to the corresponding templates 3112 and communicate with the top die groove 313. Each template 3112 is also provided with a vacuum breaking valve 333 communicating with the corresponding top die groove 313. Before glue injection, the vacuum pump 331 is turned on and the three die cavities are evacuated. The negative pressure environment in the die cavity can facilitate the flow of glue to prevent the air in the die cavity from affecting the glue injection, effectively improving the uniformity of the glue injection.

[0036] In this embodiment, there are six groups of glue filling assemblies 32. Every two groups of glue filling assemblies 32 correspond to one template 3112. Each group of glue filling assemblies 32 respectively includes a glue bucket 321, a glue pump 322, and a glue gun 326 that are sequentially connected through a pipeline 325. A glue needle 323 is arranged at the end of the glue gun 326. The two glue needles 323 that form two groups of glue filling assemblies 32 are inserted into the corresponding same template 3112 and communicate with the upper mold cavity 313. The two glue needles 323 can simultaneously fill the diagonal positions of the same screen with glue. At the same time, the glue needle 323 can always be in a docking state with the upper mold base 311 during the glue filling process, without the need to position the glue needle 323, which can ensure that the glue is accurately poured into the upper mold cavity 313.

[0037] In this embodiment, each group of glue filling assemblies 32 also respectively includes an exhaust module 324. The exhaust module 324 and the glue pump 322 are both arranged in an installation box 5 on the upper part of the machine base 4. The exhaust module 324 includes a transparent exhaust seat 3241, a glue conveying pipe 3242 penetrating through the exhaust seat 3241, and a three-way valve 3243. There are two glue pumps 322, and these two glue pumps 322 are respectively connected to the glue bucket 321 and the glue gun 326. The exhaust module 324 is arranged between the two glue pumps 322. One end of the glue conveying pipe 3242 is communicated with the first glue pump 322, and the other end is communicated with the inlet of the three-way valve 3243. One of the outlets of the three-way valve 3243 is a glue outlet communicated with the glue needle 323, and the other outlet is an exhaust port for discharging air bubbles. The glue outlet is communicated with the second glue pump 322.

[0038] A camera (not shown in the figure) is arranged above the exhaust seat 3241. The camera can photograph the glue flow condition in the exhaust seat 3241 and feedback it to the control system. The control system is a PLC controller (not shown in the figure) arranged on the machine base 4. If the glue in the exhaust seat 3241 flows normally, the control system controls the three-way valve 3243 to remain in the glue outlet path. At this time, the inlet of the three-way valve 3243 is connected to the glue outlet. If air bubbles appear in the exhaust seat 3241, the control system controls the three-way valve 3243 to switch to the exhaust path. At this time, the inlet of the three-way valve 3243 is communicated with the exhaust port, and the air bubbles can be output from the exhaust port, preventing the glue with air bubbles from being poured into the mold cavity and affecting the glue filling quality of the screen.

[0039] In this embodiment, the glue filling mechanism 3 further includes three glue cleaning components 34. Each glue cleaning component 34 is respectively used to clean the glue of two groups of glue filling components 32 corresponding to the same template 3112. Each glue cleaning component 34 respectively includes a glue discharging box 345 which is liftable and translatable along the direction close to or away from the glue filling station, two glue cleaning seats 341 installed on the glue discharging box 345, a glue cleaning groove 342 opened on the glue cleaning seat 341 for inserting the glue needle 323, and a blowing air pipe 343 arranged on the glue cleaning seat 341. The two glue cleaning seats 341 are respectively used to clean the glue needles 323 on two groups of glue filling components 32 corresponding to the same template 3112. The glue cleaning groove 342 is communicated with the glue discharging box 345. One end of the blowing air pipe 343 is communicated with the glue cleaning groove 342, and the other end is communicated with a blowing air module. The glue cleaning component 34 further includes a second driving module 344 for driving the glue cleaning seat 341 to move.

[0040] Among them, the blowing air module is an air pump in the prior art, which can output compressed air outward; the moving direction of the glue discharging box 345 is the same as the width direction of the machine base 4. The second driving module 344 is a cylinder for driving the glue discharging box 345 to lift. The translation of the glue discharging box 345 is driven by the linear motor constituting the first driving module 315. That is to say, the corresponding glue discharging box 345 and the lower die base 312 are arranged on the same linear motor. The bottom of the glue discharging box 345 bears a second sliding seat 346. The second sliding seat 346 is slidably connected with the linear motor. The cylinder is installed on the second sliding seat 346, and the piston rod of the cylinder is connected with the glue discharging box 345. Before starting glue filling, the glue discharging box 345 is translated to the glue filling station, then rises and docks with the upper die groove 313. The glue needle 323 is inserted into the glue cleaning groove 342. Subsequently, the blowing air module blows the glue on the glue needle 323, and the dropped waste glue falls into the glue discharging box 345. After the glue cleaning is completed, the glue discharging box 345 resets. Subsequently, the lower die base 312 moves and is clamped with the upper die base 311.

[0041] In this embodiment, the conveying mechanism 1 includes two conveyor belt assemblies 11 arranged side by side and extending along the length direction of the machine base 4, and two lifting assemblies 12 corresponding to the two conveyor belt assemblies 11 respectively.

[0042] The two conveyor belt assemblies 11 are respectively used for loading and unloading the screen carrier. After the conveyor belt assembly 11 for loading transports the carrier in place, the blocking block 126 can rise and block the carrier, the first clamping module 124 clamps the carrier, the lifting plate 122 rises and bears the carrier, and then the first clamping module 124 releases the carrier, and the lifting plate 122 continues to rise and docks with the transfer assembly to reduce the transfer stroke of the transfer assembly and facilitate the transfer assembly to grab the carrier; when the transfer assembly transfers the screen with glue injection completed to the conveyor belt assembly 11 for unloading, the lifting plate 122 bears the carrier and drives the carrier to descend. When the carrier descends onto the conveyor belt assembly 11, the blocking block 126 rises and blocks the carrier, the first clamping module 124 clamps the carrier, the blocking block 126 descends, the first clamping module 124 releases the carrier, and the carrier is stably output on the conveyor belt assembly 11.

Each second clamping module 24 includes two clamping jaws, and the seventh driving module 25 is a clamping jaw cylinder for driving the two clamping jaws to open and close.

[0045] When the transfer seat 22 reaches the lower die base 312, one of the two groups of second clamping modules 24 grabs the screen that has been glued in the lower die base 312, and the other group of second clamping modules 24 places the unglued screen into the lower die groove 314; when the transfer seat 22 reaches the conveying mechanism 1, one of the two groups of second clamping modules 24 places the screen that has been glued onto the conveyor belt assembly 11 for unloading, and the other clamping module 24 grabs the screen on the conveyor belt assembly 11 for loading.
