[0035] Specifically, please refer to Figures 1 to 5 , an embodiment of the present application provides a glue supply device. The glue supply device includes a machine body 10 and at least two glue spraying modules 20. The machine body 10 is configured with a heating cavity. The heating cavity forms a first glue inlet 110 and at least two first glue outlets 120 on the outer surface of the machine body 10. At least two glue spraying modules 20 are all installed on the machine body 10. Each glue spraying module 20 corresponds to and is connected to a first glue outlet 120. Among them, at least two glue spraying modules 20 are arranged at intervals.

[0036] In some embodiments, the molten glue is reheated through the heating cavity in the machine body 10 to facilitate spraying it onto the backplane. Based on the fact that at least two glue spraying modules 20 are installed on the machine body 10 at intervals, at least two glue spraying modules 20 can spray glue simultaneously to form at least two glue layers, thereby improving the glue spraying efficiency.

[0037] At least two glue spraying modules 20 can be arranged at intervals in the horizontal direction. For example, the glue spraying modules 20 are set to two, and the two glue spraying modules 20 are arranged at intervals in the left-right direction, or the two glue spraying modules 20 are arranged at intervals in the front-back direction. The heights of at least two glue spraying modules 20 can be flush.

[0038] In some embodiments, the distance between every two adjacent glue spraying modules 20 can be set to 1 cm to 15 cm (centimeters). For example, the glue spraying modules 20 are set to two, and the distance between the two glue spraying modules 20 is 5 cm. Among them, the distance between every two adjacent glue spraying modules 20 can be actually selected based on the model of the display backplane, or reasonably selected based on the glue spraying requirements. The present application does not limit the distance value between every two adjacent glue spraying modules 20.

[0039] A heating mechanism can be arranged in the machine body 10, and the heating mechanism is used to reheat the molten glue. Among them, the heating mechanism can adopt a heating resistor. For example, a resistance wire is arranged in the machine body 10, and the resistance wire is arranged around the heating cavity.

[0040] A power interface line is also electrically connected to the body 10. The power interface line is used to connect to the 220V (volt) mains power supply, so as to supply power to the heating wire and realize the heating of the heating wire. The 220V mains power supply can also supply power to the following air supply mechanism 50 and pressure regulating mechanism 60 to realize the ejection of the melted glue.

[0041] Among them, the number of the first glue inlet 110 is only set to one. The first glue inlet 110 is used to communicate with the glue melting furnace. It can be understood that the glue melting furnace is constructed with a glue outlet pipe of a certain length. The glue outlet pipe is connected to the first glue inlet 110 to input the melted glue from the first glue inlet 110 into the heating cavity to realize the secondary heating of the melted glue.

[0042] The power and capacity of the glue melting furnace are large enough to support multiple spraying modules 20 to spray glue simultaneously.

[0043] Based on the glue outlet pipe of the glue melting furnace, the temperature of the melted glue will drop to a certain extent. The heating mechanism in the body 10 performs secondary heating on the melted glue located in the heating cavity to ensure normal glue spraying. Among them, the secondary heating temperature of the heating mechanism for the melted glue is 180°C to 200°C (degrees Celsius).

[0044] Such as Figure 3 and Figure 4 As shown, in some embodiments, a spraying cavity 210 is formed in the spraying module 20. The spraying cavity 210 forms a second glue inlet 220, a second glue outlet 230 and an adjustment port 240 on the outer surface of the spraying module 20. The second glue inlet 220 is communicated with the first glue outlet 120. The second glue outlet 230 is connected with a nozzle 250. The adjustment port 240 is connected with an adjusting member 260. The adjusting member 260 is configured to adjust the volume of the spraying cavity 210.

[0045] It can be understood that the melted glue in the heating cavity can flow into the spraying cavity 210 from the first glue outlet 120 and the second glue inlet 220, and be ejected from the second glue outlet 230 and the nozzle 250 to realize the glue coating on the back plate. The adjusting member 260 is installed at the adjustment port 240 of the spraying module 20 to adjust the volume of the spraying cavity 210. Thus, the spraying cavity 210 of a suitable size can be adjusted based on different usage requirements to control the spraying effect of the melted glue.

[0046] Generally speaking, the nozzle 250 of the spraying module 20 is located at its bottom. Thus, the second glue outlet 230 is usually arranged on the lower surface of the spraying module 20 and is communicated with the spraying cavity 210. For the convenience of adjustment, the adjustment port 240 is usually arranged opposite to the second glue outlet 230. Thus, the adjustment port 240 is usually arranged on the upper surface of the spraying module 20 and is communicated with the spraying cavity 210. Among them, the second glue inlet 220 is located on the side surface of the spraying module 20. To adapt to the glue inlet of spraying cavities 210 of different sizes, the second glue inlet 220 is usually arranged at a position close to the second glue outlet 230.

[0047] Please refer to Figure 4 Figure 4 , in some embodiments, the adjusting member 260 includes an adjusting portion 2610 and a driving portion 2620. The adjusting portion 2610 is disposed in the spraying cavity 210. The circumferential side of the adjusting portion 2610 is in contact with the cavity wall surface of the spraying cavity 210. The adjusting portion 2610 is spaced apart from the second glue outlet 230, and the area between the adjusting portion 2610 and the second glue outlet 230 is defined as the volume of the spraying cavity 210. One end of the driving portion 2620 is located outside the spraying cavity 210, and the other end passes through the adjusting opening 240 and is disposed in the spraying cavity 210 and is connected to the adjusting portion 2610. The driving portion 2620 is configured to drive the adjusting portion 2610 to move to change the distance between the adjusting portion 2610 and the second glue outlet 230.

[0048] It can be understood that after the circumferential side of the adjusting portion 2610 is in contact with the cavity wall surface of the spraying cavity 210, based on the driving portion 2620 driving the adjusting portion 2610 to move in the direction close to the second glue outlet 230, the volume of the spraying cavity 210 can be reduced. Based on the driving portion 2620 driving the adjusting portion 2610 to move in the direction away from the second glue outlet 230, the volume of the spraying cavity 210 can be increased.

[0049] Among them, the spraying cavity 210 is usually set as a cylindrical cavity, and the adjusting portion 2610 can be a circular plate. The diameter of the adjusting portion 2610 is the same as the diameter of the spraying cavity 210.

[0050] The driving portion 2620 is a rotatable mechanism, and the driving portion 2620 changes the distance between the adjusting portion 2610 and the second glue outlet 230 through its own rotation.

[0051] For example, the driving portion 2620 can be set as a bolt, and the adjusting opening 240 is configured with internal threads. The driving portion 2620 is threadedly connected to the adjusting opening 240. At the same time, based on the rotation of the driving portion 2620, the length of the driving portion 2620 passing through the inside of the spraying cavity 210 is adjusted. When the driving portion 2620 is screwed into the spraying cavity 210, the adjusting portion 2610 will move in the direction close to the second glue outlet 230. Thus, the distance between the adjusting portion 2610 and the second glue outlet 230 is reduced, thereby reducing the volume of the spraying cavity 210. When the driving portion 2620 is screwed out of the spraying cavity 210, the adjusting portion 2610 will move in the direction away from the second glue outlet 230. Thus, the distance between the adjusting portion 2610 and the second glue outlet 230 is increased, thereby increasing the volume of the spraying cavity 210.

[0052] For example, the driving part 2620 can be set as a lead screw. The adjusting port 240 is configured with a bearing, and the lead screw is connected to the inner ring of the bearing. At this time, an installation hole can be opened in the adjusting part 2610, and a ball bearing is installed in the installation hole. At the same time, a limiting groove can be configured around the adjusting part 2610, and a limiting post extending along the height direction of the cavity wall surface of the spraying cavity 210 is configured on the cavity wall surface of the spraying cavity 210, so that the limiting post is clamped in the limiting groove. Thus, based on the rotation of the lead screw, the adjusting part 2610 can be driven to slide along the height direction of the spraying cavity 210. When the lead screw rotates clockwise, the adjusting part 2610 will move towards the direction close to the second glue outlet 230. Thus, the distance between the adjusting part 2610 and the second glue outlet 230 is reduced, thereby reducing the volume of the spraying cavity 210. When the lead screw rotates counterclockwise, the adjusting part 2610 will move towards the direction away from the second glue outlet 230. Thus, the distance between the adjusting part 2610 and the second glue outlet 230 is increased, thereby increasing the volume of the spraying cavity 210.

[0053] The driving part 2620 can also be a retractable structure, and the driving part 2620 changes the distance between the adjusting part 2610 and the second glue outlet 230 by the expansion and contraction of its own piston rod.

[0054] For example, the driving part 2620 can be set as a linear motor. The piston rod of the linear motor penetrates through the adjusting port 240 and is arranged in the spraying cavity 210. When the piston rod extends, the adjusting part 2610 will move towards the direction close to the second glue outlet 230. Thus, the distance between the adjusting part 2610 and the second glue outlet 230 is reduced, thereby reducing the volume of the spraying cavity 210. When the piston rod retracts, the adjusting part 2610 will move towards the direction away from the second glue outlet 230. Thus, the distance between the adjusting part 2610 and the second glue outlet 230 is increased, thereby increasing the volume of the spraying cavity 210.

[0055] Please refer to Figure 3 , in some embodiments, the second glue inlet 220 is connected with a glue inlet joint 270, and a filter screen is sleeved on the glue inlet joint 270, wherein the glue inlet joint 270 penetrates through the first glue outlet 120.

[0056] It can be understood that the glue inlet joint 270 is inserted into the first glue outlet 120 to realize the mutual conduction between the spraying glue module 20 and the machine body 10. Among them, the filter screen sleeved on the glue inlet joint 270 plays the role of filtering the molten glue. Thus, the purity of the molten glue can be improved, the nozzle 250 can be prevented from being blocked, the production efficiency and product quality can be improved. At the same time, the maintenance cost can be reduced, and the service life of the equipment can be prolonged.

[0057] Among them, through holes are configured on the outer surface of the glue inlet joint 270, and the through holes are communicated with the channels inside the glue inlet joint 270. The filtered molten glue falls into the channels inside the glue inlet joint 270 through the through holes and flows into the spraying cavity 210 from the channels.

[0058] The filter screen can be a high-temperature resistant filter screen to prevent the molten glue from damaging the filter screen. The filter screen is detachably sleeved on the glue inlet joint 270 for easy disassembly. After the glue supply device has worked for a certain period, the filter screen can be disassembled for cleaning or directly replaced with a new one, so as to ensure the filtering effect and the flow rate of the molten glue.

[0059] Please refer to Figure 1 , in some embodiments, a first fixing member 30 and a second fixing member 40 are provided on the body 10. The body 10 is arranged as a quadrilateral, and the first fixing member 30 and the second fixing member 40 are respectively located on adjacent sides of the body 10.

[0060] It can be understood that both the first fixing member 30 and the second fixing member 40 can fix the body 10 to the area to be installed. After the body 10 is fixed by using the first fixing member 30 or the second fixing member 40, subsequent spraying is carried out. Since the first fixing member 30 and the second fixing member 40 are located on adjacent sides of the body 10, it is possible to choose to fix the body 10 by using the first fixing member 30 or the second fixing member 40 based on the actual situation. Based on the selection of the first fixing member 30 and the second fixing member 40, the distribution of at least two glue spraying modules 20 can be adjusted to meet different glue application requirements.

[0061] For example, when it is necessary to obtain multiple parallel distributed glue layers, the body 10 can be installed in the area to be installed by using the first fixing member 30. At this time, the interval direction of at least two glue spraying modules 20 is perpendicular to the moving direction of the back plate. Thus, at least two parallel distributed glue layers can be formed on the back plate.

[0062] For example, when it is necessary to obtain a thickened glue layer, the body 10 can be installed in the area to be installed by using the second fixing member 40. At this time, the interval direction of at least two glue spraying modules 20 is the same as the moving direction of the back plate. Thus, a thicker glue layer can be formed on the back plate.

[0063] Please refer to Figure 5 , in some embodiments, the first fixing member 30 includes a first fixing portion 310 and a first connecting portion 320 which are connected at an angle. The first fixing portion 310 is configured with a first fixing hole 330. The first fixing hole 330 is connected to the body 10 through a first fastener. The first connecting portion 320 is configured with a first mounting notch 340. The first mounting notch 340 is configured to be fixed to the area to be installed through a second fastener.

[0064] It can be understood that the first fixing portion 310 is used to connect with the body 10, and the first connecting portion 320 is used to connect with the area to be installed. Thus, the body 10 is fixed to the area to be installed. Among them, the first fixing portion 310 is fixed to the body 10 by a first fastener passing through the first fixing hole 330, and the first fastener also passes through the threaded hole of the body 10. The first connecting portion 320 is fixed to the area to be installed by a second fastener passing through the first installation notch 340, and the second fastener also passes through the threaded hole of the area to be installed.

[0065] The first fixing portion 310 and the first connecting portion 320 can be integrally formed. The first fixing portion 310 and the second fixing portion are vertically connected to form a first fixing member 30 that is generally L-shaped. Among them, both the first fastener and the second fastener are bolts.

[0066] Based on the construction of the first installation notch 340 on the first connecting portion 320, the first installation notch 340 can extend a certain length along the first connecting portion 320, so as to facilitate adjusting the relative position between the first connecting portion 320 and the area to be installed, and thus adjusting the fixing position of the body 10. Among them, if the first connecting portion 320 extends in the height direction, the first installation notch 340 also extends in the height direction to adjust the fixing position of the body 10 in the height direction of the area to be installed.

[0067] In some embodiments, the second fixing member 40 includes a second fixing portion and a second connecting portion that are angularly connected. The second fixing portion is provided with a second fixing hole. The second fixing hole is connected to the body 10 by a third fastener. The second connecting portion is provided with a second installation notch. The second installation notch is configured to be fixed to the area to be installed by a fourth fastener.

[0068] It can be understood that the second fixing portion is used to connect with the body 10, and the second connecting portion is used to connect with the area to be installed. Thus, the body 10 is fixed to the area to be installed. Among them, the second fixing portion is fixed to the body 10 by a third fastener passing through the second fixing hole, and the third fastener also passes through the threaded hole of the body 10. The second connecting portion is fixed to the area to be installed by a fourth fastener passing through the second installation notch, and the fourth fastener also passes through the threaded hole of the area to be installed.

[0069] The second fixing portion and the second connecting portion can be integrally formed. The second fixing portion and the second fixing portion are vertically connected to form a second fixing member 40 that is generally L-shaped. Among them, both the third fastener and the fourth fastener are bolts.

[0070] By constructing a second mounting notch on the second connecting portion, the second mounting notch can extend along the second connecting portion for a certain length, thereby facilitating the adjustment of the relative position between the second connecting portion and the area to be mounted, so as to adjust the fixing position of the body 10. Wherein, the second connecting portion can extend in the height direction, and the second mounting notch also extends in the height direction to adjust the fixing position of the body 10 in the height direction of the area to be mounted.

[0071] As Figure 3 shown, in some embodiments, the glue spraying module 20 is configured with a thimble hole 280. A thimble valve is provided in the thimble hole 280. The thimble valve is configured to control the on-off of the glue spraying module 20 and the first glue outlet 120. Wherein, the thimble valve makes the glue spraying module 20 communicate with the first glue outlet 120 under the action of air pressure.

[0072] It can be understood that the thimble valve has a first state and a second state. In the first state, the thimble valve controls the communication between the glue spraying module 20 and the first glue outlet 120. At this time, the molten glue in the heating cavity can flow from the first glue outlet 120 into the spraying cavity 210 of the glue spraying module 20. In the second state, the thimble valve controls the disconnection between the glue spraying module 20 and the first glue outlet 120. At this time, the molten glue in the heating cavity cannot flow from the first glue outlet 120 into the spraying cavity 210 of the glue spraying module 20. Wherein, the thimble valve can be switched from the second state to the first state under the action of air pressure. That is: when gas is blown into the thimble hole 280, the thimble valve can be driven to switch from the second state to the first state. When the gas is withdrawn, the thimble valve switches from the first state to the second state based on self-return.

[0073] Wherein, the thimble valve has an elastic member. When gas is blown into the thimble hole 280, the gas pushes the thimble valve to act so that the thimble valve switches from the second state to the first state. During this process, the elastic member gradually contracts. When the gas is withdrawn, the elastic member pushes the thimble valve to reset through self-return so that the thimble valve switches from the first state to the second state.

[0074] In some embodiments, the thimble hole 280 can communicate with the spraying cavity 210, and the gas entering and leaving the thimble hole 280 can flow into the spraying cavity 210 and finally be discharged from the nozzle 250.

[0075] As Figure 1 and Figure 2 shown, in some embodiments, the glue supply device further includes a gas supply mechanism 50. The gas supply mechanism 50 is installed on the body 10. The gas supply mechanism 50 is connected with a first gas supply pipe 510. A gas guiding channel is formed in the body 10. One end of the gas guiding channel communicates with the first gas supply pipe 510, and the other end communicates with the thimble hole 280.

[0076] By setting the air supply mechanism 50 to input pressurized air flow into the thimble valve, the driving of the thimble valve is achieved. Among them, a conductor channel intake port and a conductor channel outlet port are formed on the surface of the body 10 for the conductor channel. The air guide channel intake port 130 is communicated with the first air supply pipe 510, and the conductor channel outlet port is communicated with the thimble hole 280. Specifically, the pressurized air flow generated by the air supply mechanism 50 is blown into the thimble hole 280 from the first air supply pipe 510 and the air guide channel, thereby driving the thimble valve to switch from the second state to the first state. At this time, the molten glue in the heating chamber can flow into the spraying chamber 210 of the spraying module 20 from the first glue outlet 120 to achieve glue spraying.

[0077] Among them, the air supply mechanism 50 can adopt an air supply solenoid valve.

[0078] Please continue to refer to Figure 1 , in some embodiments, the glue supply device further includes a pressure regulating mechanism 60. The pressure regulating mechanism 60 is installed on the spraying module 20. The air supply mechanism 50 is also connected with a second air supply pipe 520. The second air supply pipe 520 is communicated with the intake end of the pressure regulating mechanism 60. The outlet end of the pressure regulating mechanism 60 is communicated with the spraying module 20, and is used to drive the molten glue in the spraying module 20 to spray out from the nozzle 250 of the spraying module 20.

[0079] It can be understood that, on the one hand, the pressure regulating mechanism 60 can receive the pressurized air flow output from the second air supply pipe 520 of the air supply mechanism 50 and input the pressurized air flow into the spraying module 20, so that the molten glue in the spraying module 20 sprays out from the nozzle 250 to achieve glue spraying. On the other hand, the pressure regulating mechanism 60 can also adjust the air pressure input by the air supply mechanism 50 into the spraying module 20 to control the glue spraying effect. The greater the air pressure set by the pressure regulating mechanism 60, the wider, thinner and sparser the glue layer formed by the sprayed molten glue. The smaller the air pressure set by the pressure regulating mechanism 60, the narrower, thicker and denser the glue layer formed by the sprayed molten glue. Thus, the output air pressure of the pressure regulating mechanism 60 can be set based on different glue spraying requirements to form a glue layer adapted to the usage scenario.

[0080] Among them, the pressure regulating mechanism 60 can adopt a constant pressure valve.

[0081] In some embodiments, both the air supply mechanism 50 and the pressure regulating mechanism 60 are set to at least two, and each spraying module 20 corresponds to an air supply mechanism 50 and a pressure regulating mechanism 60.

[0082] It can be understood that if the air supply mechanism 50, the pressure regulating mechanism 60 and the spraying module 20 correspond one by one, then according to needs, one or some of the spraying modules 20 can be selected to work, based on turning on the air supply mechanism 50 and the pressure regulating mechanism 60 corresponding to one or some of the spraying modules 20. Thus, independent control of each spraying module 20 can be achieved, which is more suitable for the production working conditions in application and improves the practicability.

[0083] The glue supply device provided by the embodiment of the present application has a length controlled between 13 cm and 15 cm and a width controlled between 5 cm and 7 cm. With a relatively small overall size, it can prevent the glue supply device from colliding with the robotic arm and causing interference, and is also conducive to the maintenance of the glue supply device. For example, the length of the glue supply device is set to 13.4 cm and the width is set to 6 cm. By arranging at least two glue spraying modules 20 on a body 10, the glue supply device can not only improve the glue spraying efficiency but also enhance the utilization rate of the melting furnace.
