Description

Technical Field

[0001] The present invention relates to the technical field of glue filling, and particularly to a high-precision glue discharging mechanism of a glue filling machine. Background Art

[0002] A glue filling machine is a device used in industrial production, mainly for coating or spraying glue or sealant on products during the manufacturing process. Glue filling machines are usually applied in industries such as electronics, automotive, aerospace, and furniture, for precise glue coating during product assembly, packaging, or processing. A glue filling machine generally includes components such as a control system, a glue storage and conveying system, and a glue discharging mechanism. Among them, the glue discharging mechanism of the glue filling machine refers to the components and mechanisms used to output glue or sealant from the glue filling machine and coat it on the surface of the target object. The design of the glue discharging mechanism has an important impact on the performance of the glue filling machine and the glue coating effect.

[0003] Currently, the glue discharging mechanism of the glue filling machine has a simple structure and low functionality. During its operation, since it uses pressure as the driving force, when the pressure control is improper, glue leakage will occur when the pressure is too high or too low, resulting in waste during the production process and an increase in the defective rate. In addition, the channels of the glue discharging mechanism will be blocked due to glue solidification or impurities, resulting in abnormal glue outflow and affecting production efficiency. Moreover, currently, general glue filling machines only allow one or two glue discharging mechanisms to be used simultaneously, and the glue discharging mechanisms are generally fixed on the glue filling machine, making it impossible to quickly replace them when they are damaged, thus affecting production efficiency. Summary of the Invention

[0006] Preferably, the driving component includes an air pump, the outer wall of the air pump is fixedly connected to the top of the mounting seat, the driving end of the air pump is fixedly connected to a conduit, and the other end of the conduit is fixedly connected to the top of the housing.

[0007] Preferably, an inner liner is fixedly connected to the inner wall of the housing, a connecting pipe penetrates and connects the outer walls of the inner liner and the housing, and a push plate is slidably connected to the inner wall of the inner liner.

[0008] Preferably, a leak-proof component is arranged at the bottom of the inner liner, a trachea penetrates and connects to the outer wall of the conduit, an electromagnetic valve is connected to the middle of the trachea, and a clamping component is fixedly connected to the bottom of the trachea.

[0009] Preferably, the leak-proof component includes a plurality of movable blades, the tops of the plurality of movable blades are rotatably connected to the bottom of the inner liner, a plurality of groups of connecting rods are rotatably connected between the inner liner and the movable blades, a moving plate is fixedly connected to the opposite side of each group of connecting rods, a sleeve is slidably connected to the outer wall of each moving plate, and a third spring is fixedly connected to the opposite side of every two opposite moving plates.

[0010] Preferably, the clamping component includes a fixed pipe frame, the top of the fixed pipe frame is fixedly connected to the bottom of the housing, two pistons are slidably connected to the inner wall of the fixed pipe frame, a moving frame is fixedly connected to the opposite side of each of the two pistons, a fourth spring is sleeved outside the two moving frames, the outside of the fourth spring is arranged inside the fixed pipe frame, an arc plate is fixedly connected to the opposite side of each of the two moving frames, and the outer walls of the two arc plates are in contact with the outer walls of the plurality of movable blades.

[0011] Preferably, two sliding grooves are formed in the outer wall of the mounting seat, and L-shaped insertion rods are slidably connected to the inner walls of the two sliding grooves. A plurality of insertion holes are formed in the upper surface of the moving seat.

[0012] Preferably, a vacuum gas is filled between the outer shell and the inner tank.

[0013] Working principle: When using a glue filling machine for glue filling processing, according to the actual glue filling situation, select the required number of glue outlet mechanisms, and then sequentially install and fix the glue outlet mechanisms on the outer wall of the moving seat. Just align the socket on the mounting seat with the connecting seat, and then press the pressing sleeve. When pressing, as the pressing sleeve slides on the inner wall of the mounting seat, after contacting the second spring, it will squeeze the second spring, causing the second spring to compress. At the same time, the second ball will separate from the inner wall of the pressing sleeve, and the pressing sleeve will push the annular plate to move on the inner wall of the mounting seat, squeezing the first spring to compress it. At the same time, as the annular plate moves, the third ball will contact the recess on the outer wall of the socket. At this time, as the third ball enters the recess, it will relatively squeeze the socket, thereby pushing the socket to move away from the connecting seat, and then driving the first ball to move on the outer wall of the connecting seat, and then pushing the first ball into the first limiting groove. At this time, the hole on the socket opens. Then, push the socket towards the connecting seat, so that the connecting seat enters the hole on the socket. During the process when the outer wall of the mounting seat is in close contact with the outer wall of the moving seat, the pressing sleeve can be released. Under the reaction force of the second spring and the first spring, the first ball on the socket contacts the recess on the outer wall of the connecting seat, so that the socket is stuck outside the connecting seat, thus completing the fixation of the glue outlet mechanism on the outer wall of the moving seat. At this time, connect the tube on the glue bucket to the connecting tube to start the glue filling processing. When filling the glue, start the air pump to generate gas. The gas enters the inner tank through the conduit, and then pushes the push plate to move downward on the inner wall of the inner tank, and then pushes the glue out from the bottom. At the same time, according to the required amount of gas, through the solenoid valve, part of the gas can be controlled to enter the trachea, and then enter the fixed pipe rack, pushing the pistons on both sides to move in opposite directions, thereby squeezing the fourth spring, causing the fourth spring to compress and generate a reaction force. And driven by the pistons, the moving frame moves in the opposite direction, so that the two arc-shaped plates separate. At this time, as the glue at the bottom of the inner tank is removed, the glue will push a plurality of movable blades to open, and then the connecting rod moves in the sleeve, and then drives the moving plate to stretch the third spring, generating a reaction force of springback. When the glue filling is completed and the air pump stops delivering gas into the inner tank, the stretched third spring will quickly drive the two connecting rods to reset, and then several movable blades will close. At the same time, the compressed fourth spring generates a reaction force of springback, so that the arc-shaped plates on both sides reset. Then, under the relative extrusion of the arc-shaped plates on both sides, the closing of several movable blades is promoted, thus avoiding the occurrence of glue leakage.

[0014] The present invention provides a high-precision glue dispensing mechanism for a glue filling machine, with the following beneficial effects:

[0015] 1. By pressing the pressing sleeve in the present invention, the connecting seat can enter the holes on the socket. Subsequently, when the pressing sleeve is released, the two-sided ball bearings are stuck in the recesses on the outer wall of the socket, so that the mounting seat is fixedly installed on the outer wall of the moving seat, thus realizing the simultaneous use of multiple glue dispensing mechanisms, making the glue filling machine more applicable, improving the glue filling efficiency, and being able to quickly replace the damaged glue dispensing mechanism, further ensuring the working efficiency.

[0016] 2. By designing two layers of glue hoses and injecting vacuum gas between the outer shell and the inner liner in the present invention, the heat inside the pipe body cannot be transferred out, thus ensuring that the temperature of the glue during the glue filling process will not quickly cool down, which is beneficial to improving the glue filling quality, avoiding the waste of glue, and at the same time preventing the glue from solidifying inside the pipeline.

[0017] 3. By introducing a certain amount of gas into the fixed pipe rack of the clamping assembly in the present invention, the two-sided arc-shaped plates are opened, releasing the extrusion on several movable blades. And after the glue filling is completed, when the injection of gas stops, the two-sided arc-shaped plates quickly close, thus pushing the multiple movable blades to quickly close, thereby avoiding the occurrence of excess metered glue droplets falling, and ensuring the glue dispensing accuracy of the glue dispensing mechanism.

[0018] 4. By providing a leak-proof component at the bottom of the inner liner in the present invention, it is ensured that after the glue filling, the glue will not drip and at the same time prevent dust and other impurities from entering the inside of the inner liner to contaminate the glue, thus ensuring the glue filling quality.

Detailed implementation manners

[0032] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment:

[0034] Please refer to the attached Figure 1 - attached Figure 4, an embodiment of the present invention provides a high-precision glue dispensing mechanism for a glue filling machine, including a linear guide rail 1. A moving seat 2 is arranged outside the linear guide rail 1. A plurality of connecting seats 3 are connected to the outer wall of the moving seat 2. Mounting seats 4 are sleeved outside each of the plurality of connecting seats 3. A socket 5 is arranged inside each mounting seat 4. The socket 5 is sleeved on the outer wall of the connecting seat 3. A first limiting groove 6 is opened on both sides of the socket 5. A first ball 7 is arranged on the inner wall of each first limiting groove 6. A first spring 8 is sleeved on the outer wall of the socket 5. A circular plate 9 is slidably connected to the inner wall of each mounting seat 4. The outside of the first spring 8 is arranged at the rear side of the circular plate 9. An installation groove 11 is opened on the front side of the socket 5. A second spring 10 is fixedly connected to the inner wall of the installation groove 11. A second limiting groove 12 is opened on both sides of the socket 5. A pressing sleeve 14 is slidably connected to the inner wall of the mounting seat 4. The inner wall of the pressing sleeve 14 is in contact with the outer wall of the socket 5. A second ball 13 is arranged on the inner walls of the second limiting groove 12 and the pressing sleeve 14. Two third balls 15 are arranged between the pressing sleeve 14 and the circular plate 9. A driving assembly is fixedly connected to the top of the mounting seat 4. A housing 18 is fixedly connected to the front side of the mounting seat 4.

[0035] Specifically, the glue dispensing mechanism is installed and fixed on the outer wall of the moving seat 2. Only need to align the socket 5 on the mounting seat 4 with the connecting seat 3, and then press the pressing sleeve 14. When pressing, as the pressing sleeve 14 slides on the inner wall of the mounting seat 4, after contacting the second spring 10, it will squeeze the second spring 10, causing the second spring 10 to compress. At the same time, the second ball 13 will separate from the inner wall of the pressing sleeve 14, and the pressing sleeve 14 will push the annular plate 9 to move on the inner wall of the mounting seat 4, squeezing the first spring 8 to compress it. At the same time, as the annular plate 9 moves, the third ball 15 will contact the recess on the outer wall of the socket 5. At this time, as the third ball 15 enters the recess, it will relatively squeeze the socket 5, thereby pushing the socket 5 to move away from the connecting seat 3, and then driving the first ball 7 to move on the outer wall of the connecting seat 3, and then pushing the first ball 7 into the first limiting groove 6. At this time, the hole on the socket 5 is opened, and then push the socket 5 towards the connecting seat 3, so that the connecting seat 3 enters the hole on the socket 5. During the process when the outer wall of the mounting seat 4 is in close contact with the outer wall of the moving seat 2, the pressing sleeve 14 can be released. Under the reaction force of the second spring 10 and the first spring 8, the first ball 7 on the socket 5 contacts the recess on the outer wall of the connecting seat 3, so that the socket 5 is stuck outside the connecting seat 3, thus completing the fixation of the glue dispensing mechanism on the outer wall of the moving seat 2. Among them, both the first spring 8 and the second spring 10 will be squeezed to generate a rebounding reaction force, which helps the movement of the pressing sleeve 14 and the socket 5. At the same time, the outer wall of the connecting seat 3 is designed with a concave and smooth part, which is convenient for the first ball 7 to roll along its outer wall, thus facilitating installation and fixation and subsequent removal of fixation. At the same time, the side of the pressing sleeve 14 close to the third ball 15 is designed with an inclined surface, which is convenient for squeezing the third ball 15 to make it enter the recess on the outer wall of the socket 5. At the same time, the second ball 13 is fixed on the inner wall of the second limiting groove 12, but the other side protrudes, which is convenient for contacting the inner wall of the pressing sleeve 14 to prevent falling off. Through this installation and fixation component, multiple glue dispensing mechanisms can be used simultaneously, improving the applicability of the glue filling machine, improving the glue filling efficiency, and being able to quickly replace the damaged glue dispensing mechanism, further ensuring the working efficiency.

[0036] Please refer to the appendix Figure 1 - appendix Figure 2 , the driving component includes an air pump 16. The outer wall of the air pump 16 is fixedly connected to the top of the mounting seat 4, and the driving end of the air pump 16 is fixedly connected to a conduit 17. The other end of the conduit 17 is fixedly connected to the top of the housing 18.

[0037] Specifically, by driving the air pump 16, gas enters the inside of the conduit 17 and then enters the inside of the pipeline, which is convenient for controlling the dosage of the dispensed glue through air pressure.

[0038] Please refer to the appendix Figure 5, the inner wall of the outer shell 18 is fixedly connected with an inner tank 19. A connecting pipe 21 runs through and connects the outer walls of the inner tank 19 and the outer shell 18. A push plate 20 is slidably connected to the inner wall of the inner tank 19.

[0039] Specifically, when gas is input into the inner tank 19, the push plate 20 is pushed by the gas and will move downward inside the inner tank 19. Thus, the push plate 20 pushes out an appropriate dose of glue. At the same time, the connecting pipe 21 can be connected to the feeding pipe on the glue storage tank, thereby facilitating the conveyance of glue into the glue discharging mechanism.

[0040] A leak-proof component is provided at the bottom of the inner tank 19. An air pipe 32 runs through and connects to the outer wall of the conduit 17. A solenoid valve 33 is connected to the middle of the air pipe 32. The bottom of the air pipe 32 is fixedly connected with a clamping component.

[0041] Specifically, the solenoid valve 33 can control some gas to enter the air pipe 32, thereby driving the operation of the clamping component.

[0042] Please refer to the appendix Figure 6 and the appendix Figure 9 - appendix Figure 11 , the leak-proof component includes a number of movable blades 22. The tops of the number of movable blades 22 are rotatably connected to the bottom of the inner tank 19. Multiple groups of connecting rods 23 are rotatably connected between the inner tank 19 and the movable blades 22. The opposite sides of each group of connecting rods 23 are fixedly connected with a moving plate 25. The outer walls of each group of moving plates 25 are slidably connected with a sleeve 24. A third spring 26 is fixedly connected between the opposite sides of every two opposite moving plates 25.

[0043] Specifically, during glue discharging, under the push of the glue, the number of movable blades 22 will open, so that the connecting rods 23 drive the moving plates 25 to move in opposite directions inside the sleeves 24, thereby stretching the third spring 26. Thus, the third spring 26 generates a reaction force of resilience. After the glue discharging ends and the conveyance of glue stops, the driving force disappears. The third spring 26 generates a reaction force of resilience, thereby driving the number of movable blades 22 to close. This ensures that after glue filling, the glue will not drip and at the same time prevents dust and other impurities from entering the inner tank 19 to contaminate the glue, thus ensuring the quality of glue filling.

[0044] Please refer to the appendix Figure 7 - appendix Figure 9, the clamping assembly includes a fixed pipe bracket 27, the top of the fixed pipe bracket 27 is fixedly connected to the bottom of the outer shell 18, two pistons 28 are slidably connected to the inner wall of the fixed pipe bracket 27, a moving frame 29 is fixedly connected to the opposite side of each of the two pistons 28, a fourth spring 31 is sleeved outside the two moving frames 29, the outside of the fourth spring 31 is arranged inside the fixed pipe bracket 27, arc-shaped plates 30 are fixedly connected to the opposite sides of the two moving frames 29, and the outer walls of the two arc-shaped plates 30 are in contact with the outer walls of a plurality of movable blades 22.

[0045] Specifically, under the control of the solenoid valve 33, a certain amount of gas enters the inside of the fixed pipe bracket 27, pushing the pistons 28 on both sides to move in opposite directions, thereby squeezing the fourth spring 31, causing the fourth spring 31 to compress and generate a reaction force. And driven by the piston 28, the moving frame 29 moves in the opposite direction, so that the two arc-shaped plates 30 are separated. Subsequently, after the glue application is completed, the gas supply to the inside of the fixed pipe bracket 27 is stopped, so that the compressed fourth spring 31 generates a reaction force of resilience, thereby driving the two arc-shaped plates 30 to move relatively, and then pushing a plurality of movable blades 22 to close quickly, thus avoiding the occurrence of excessive metered glue droplets falling and ensuring the glue application accuracy of the glue application mechanism.

[0046] Please refer to the appendix Figure 12 , two chutes 34 are opened on the outer wall of the mounting seat 4, L-shaped insertion rods 35 are slidably connected to the inner walls of the two chutes 34, and a plurality of insertion holes 36 are opened on the upper surface of the moving seat 2.

[0047] Specifically, after the glue application mechanism is installed and fixed, the L-shaped insertion rod 35 is pushed downward to make it enter the corresponding insertion hole 36, thereby further fixing the glue application mechanism and avoiding damage to the connecting seat 3 due to excessive force.

[0048] A vacuum gas is filled between the outer shell 18 and the inner tank 19.

[0049] Specifically, by designing two layers of rubber hoses and injecting a vacuum gas between the outer shell 18 and the inner tank 19, the heat inside the pipe body cannot be transferred out, thereby ensuring that the temperature of the glue during the glue filling process will not cool down quickly, which is beneficial to improving the glue filling quality, avoiding waste of glue, and at the same time preventing the glue from solidifying inside the pipeline.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
