TECHNICAL FIELD
[0001] The application relates to the technical field of glue supply, in particular to a two-component screw type pressure disc pump. BACKGROUND
[0002] In the field of high-end precision manufacturing such as electronic manufacturing (such as semiconductor chip packaging), automobile assembly (such as power battery pack sealing), aerospace (such as composite material structure bonding), etc., two-component glue has become an indispensable core material for key processes such as component fixing, gap sealing and structure bonding due to its excellent bonding strength, medium corrosion resistance and sealing performance after curing. Such glue usually has high viscosity and is sensitive to the environment, so the requirements for the glue supply system are relatively strict.
[0003] Typically, on the one hand, in order to ensure that the glue coating track is regular and the glue layer is uniform, high-precision constant pressure output needs to be achieved, and the pressure fluctuation needs to be controlled within a very small range; on the other hand, in order to avoid serious quality problems such as uneven glue coating, glue layer defects, insufficient bonding strength and sealing failure, bubble-free delivery of the glue needs to be achieved, and it is necessary to ensure that air is not mixed into the delivered glue to form voids.
[0004] At present, the existing glue supply mostly adopts a screw pump. For the screw pump, the screw can be rotated by a driving device, and the helical tooth profile of the screw can push the glue to move continuously in the closed cavity along the axial direction of the screw. The periodic change of the cavity realizes the pumping and delivery of the glue. Generally, this delivery method can effectively overcome the flow resistance of the glue and ensure that the delivered glue is quantified and has stable pressure.
[0005] The above universal screw pump can only achieve quantitative and stable pressure delivery of the glue and has no reliable air exhaust function. During the pumping and delivery of the glue, air is easily mixed into the glue to form voids, the quality of the glue does not meet the supply requirements, and subsequent glue coating defects will occur, which affects the bonding and sealing quality. SUMMARY
[0006] In order to prevent the glue from forming voids as much as possible to ensure the supply quality, the application provides a two-component screw type pressure disc pump.
[0007] The two-component screw type pressure disc pump provided by the application adopts the following technical scheme: A two-component screw type pressure disc pump, comprising a glue pressing driving member, the glue pressing driving member being connected with a glue discharging mechanism, the glue discharging mechanism being connected with a pressure disc mechanism; the two-component screw type pressure disc pump further comprises a glue storage barrel. The pressure disc mechanism comprises a pumping member connected to the glue discharging mechanism and an air exhaust assembly connected to the pumping member, the air exhaust assembly comprising an air cavity in communication with the pumping member and an air exhaust channel at an end of the air cavity and capable of blocking glue.
[0008] By adopting the technical scheme, after the glue is stored in the glue storage barrel, the pressure material driving member can drive the discharging mechanism and the pressing disc mechanism to move into the glue storage barrel to contact the glue, wherein the discharging mechanism contacts the glue to discharge the glue for supply, and the pressing disc mechanism can press the glue to assist the supply of the glue and discharge the air in the glue storage barrel and the air possibly carried by the glue. Specifically, after the exhaust assembly enters the glue storage barrel, the air in the glue storage barrel reaches the air cavity through the exhaust channel, and the air in the air cavity is sucked away by the suction member, so that the glue in the glue storage barrel is discharged by the discharging mechanism without gap.
[0009] Preferably, the exhaust assembly comprises a connecting member adsorbed to the suction member and a first plate member connected to the connecting member, and the exhaust channel is formed on the first plate member and between the first plate member and the connecting member.
[0010] By adopting the technical scheme, the connecting member and the first plate member can be detached for replacement or cleaning, and other types of connecting member and first plate member can be adapted to different sizes of storage barrels and different viscosities of glue.
[0011] Preferably, the connecting member comprises a second plate member, an air cavity is formed between the first plate member and the second plate member, the second plate member is provided with a connecting structure, the suction member is adsorbed to the connecting structure, and a sealing ring is connected to the outer periphery of the second plate member, and the sealing ring has a deformation ability.
[0012] By adopting the technical scheme, the first plate member and the second plate member form a sealed air cavity, effectively preventing air leakage during air collection and ensuring the stability of the exhaust effect. The connecting structure provides a precise and firm mounting adsorption site for the suction member, ensuring the sealing of the communication between the suction member and the air cavity, and avoiding the decrease of adsorption force caused by negative pressure leakage. The sealing ring with deformation ability can tightly fit the inner wall of the storage barrel to block the mixing of external air into the glue from the gap between the exhaust assembly and the storage barrel, further improving the purity of glue transportation.
[0013] Preferably, the diameter of the sealing ring gradually decreases towards the bottom end of the glue storage barrel.
[0014] By adopting the technical scheme, the tapered design forms a natural guide when the sealing ring is installed in the storage barrel, reducing the entry resistance.
[0015] Preferably, the connecting structure is located in the sealing ring, a clamping groove is formed between the connecting structure and the sealing ring, and the discharging mechanism comprises a mounting member, and the mounting member is clamped in the clamping groove.
[0016] By adopting the technical scheme, the exhaust assembly can be separated from the discharging mechanism.
[0017] Preferably, the connecting structure comprises a vent head connected to the first plate member and a vent plug detachably mounted to the vent head.
[0018] By adopting the above technical scheme, the vent head provides a directional channel for air flow, ensuring that the air in the air cavity can flow accurately and smoothly to the suction member. The type of vent plug can be flexibly selected according to the actual working conditions such as the viscosity of the rubber material and the air content, realizing controllable adjustment of the exhaust flow. For example, for high-viscosity rubber material, a vent plug with a small vent hole diameter can be selected to avoid excessive negative pressure causing the rubber material to be sucked into the air cavity through the exhaust channel.
[0019] Preferably, the connecting member further comprises a shunt assembly connected to the second plate member, the shunt assembly being located in the air cavity, the shunt assembly having a clamping block, the first plate member having a clamping hole, and the clamping block being clamped in the clamping hole.
[0020] By adopting the above technical scheme, the shunt assembly located in the air cavity can guide the air in the air cavity, breaking the phenomenon of air accumulation in the local air cavity, making the air evenly distributed and quickly converging to the exhaust channel, and significantly improving the exhaust efficiency. At the same time, the shunt assembly is clamped and fixed with the clamping hole of the first plate member through the clamping block, which is convenient to assemble, firmly connected and easy to disassemble.
[0021] Preferably, the exhaust channel comprises an exhaust ring groove formed between the outer periphery of the first plate member and the connecting member, and a plurality of exhaust holes uniformly distributed on the first plate member.
[0022] By adopting the above technical scheme, the exhaust ring groove between the outer periphery of the first plate member and the connecting member forms a ring-shaped main exhaust channel, which cooperates with the plurality of exhaust holes uniformly distributed on the first plate member to build a high-efficiency exhaust system with multi-point air suction and ring-shaped exhaust. The plurality of uniformly distributed exhaust holes can simultaneously extract air from different areas of the rubber material, ensuring uniform exhaust and avoiding local air residue. The exhaust ring groove realizes the centralized export of air, shortens the exhaust path and increases the exhaust flow, and the two work together to further improve the exhaust efficiency, ensuring that the air in the rubber material is completely exhausted and the rubber material is bubble-free.
[0023] Preferably, the discharging mechanism comprises a mounting seat connected to a material pressing driving member, the mounting seat being connected with a discharging pipe, the mounting seat being provided with a driving rotating member, the driving rotating member being connected with a screw rod, the screw rod being located in the discharging pipe; the exhaust assembly further comprises a material running channel, the discharging pipe being in communication with the material running channel.
[0024] By adopting the above technical scheme, after the exhaust assembly enters the storage barrel, the rubber material will enter the material running channel, and at this time the driving of the driving rotating member can drive the screw rod to rotate to discharge the rubber material through the discharging pipe.
[0025] Preferably, the suction member comprises an elastic nozzle portion in contact with the exhaust assembly.
[0026] By adopting the above technical solution, the elastic nozzle portion enables the exhaust assembly to have a micro-motion capability. When the exhaust assembly contacts the rubber compound, the rubber compound has viscosity, so the exhaust assembly encounters a large resistance. Therefore, the exhaust assembly with the micro-motion capability can ensure the air exhaust reliability of the rubber compound and the structure of the exhaust assembly is not damaged.
[0027] In summary, the present application has at least one of the following beneficial technical effects: 1. After the rubber compound is stored in the storage barrel, the pressure driving member can drive the discharging mechanism and the pressure disc mechanism to move into the storage barrel to contact the rubber compound. The discharging mechanism contacts the rubber compound to discharge the rubber compound for supply, and the pressure disc mechanism can press the rubber compound to assist the supply of the rubber compound and discharge the air in the storage barrel and the air possibly carried by the rubber compound. Specifically, after the exhaust assembly enters the storage barrel, the air in the storage barrel flows into the air cavity through the exhaust passage, and the air in the air cavity is sucked away by the suction member, so that the rubber compound in the storage barrel is discharged without gaps by the discharging mechanism; 2. The vent head provides a directional passage for air flow, ensuring that the air in the air cavity can flow to the suction member accurately and smoothly. The vent plug type can be flexibly selected according to the actual working conditions such as the viscosity of the rubber compound and the air content, to realize controllable adjustment of the exhaust flow. For example, for high-viscosity rubber compound, a vent plug with a small vent hole diameter can be selected to avoid the rubber compound being sucked into the air cavity through the exhaust passage due to excessive negative pressure; 3. The elastic nozzle portion enables the exhaust assembly to have a micro-motion capability. When the exhaust assembly contacts the rubber compound, the rubber compound has viscosity, so the exhaust assembly encounters a large resistance. Therefore, the exhaust assembly with the micro-motion capability can ensure the air exhaust reliability of the rubber compound and the structure of the exhaust assembly is not damaged.

[0032] The embodiment of the application discloses a double-component screw type pressing plate pump. The double-component screw type pressing plate pump can send out rubber without gap so as to facilitate subsequent processing and use.

[0035] Reference Figure 3 and Figure 4Specifically, the moving plate 42 is provided with a plurality of first connecting holes, and the moving plate 42 is provided with a pressing piece 43 corresponding to each first connecting hole. The pressing piece 43 is provided with a second connecting hole 431, and the first connecting hole and the second connecting hole 431 can be connected with a bolt to fix the position of the pressing piece 43. A plurality of pressing pieces 43 are arranged around the glue storage barrel 5 and press the glue storage barrel 5.
[0036] After the glue is stored in the glue storage barrel 5, the pressing driving element 11 can drive the discharging mechanism 2 and the pressing disc mechanism 3 to move downward into the glue storage barrel 5 to contact the glue. The discharging mechanism 2 can send out the glue to supply the glue, and the pressing disc mechanism 3 can press the glue to assist the supply of the glue and discharge the air in the glue storage barrel 5 and the air carried by the glue.
[0037] In the present application, in order to facilitate the supply of two-component glue, the above structure is provided with two groups.
[0038] Referring to Figure 2 and Figure 5 , the discharging mechanism 2 comprises a mounting seat 21 connected to the pressing driving element 11, and the mounting seat 21 is connected with a discharging pipe 22. The discharging pipe 22 has a vertical rigid pipe 221 and a flexible pipe 222 connected to the rigid pipe 221. The mounting seat 21 is provided with a driving element 23, for example, a motor. The driving element 23 is connected with a screw rod, and the screw rod is located in the discharging pipe 22. The flexible pipe 222 is close to the top end of the screw rod. The specific structure of the screw rod is a prior art and will not be described here. The specific structure diagram of the screw rod is not shown. The air exhaust assembly 32 comprises a material passing channel 3211, and the rigid pipe 221 is communicated with the material passing channel 3211.
[0039] When the pressing disc mechanism 3 and the discharging mechanism 2 move downward into the glue storage barrel 5, the pressing disc mechanism 3 can press the glue to make the glue enter the material passing channel 3211 and then reach the discharging pipe 22. At this time, driving the driving element 23 to rotate the screw rod can make the glue be transported to the flexible pipe 222 and then be discharged.
[0040] In the present application, the conveying amount and conveying pressure of the glue are related to the screw rod speed and the screw rod shape. The higher the screw rod speed, the greater the conveying pressure and the conveying amount.
[0041] Referring to Figure 2 and Figure 5 , the discharging mechanism 2 further comprises a mounting member 24 connected to the rigid pipe 221. The pressing disc mechanism 3 comprises a suction element 31 connected to the mounting member 24 through a screw and an air exhaust assembly 32 adsorbed and fixed on the suction element 31. The suction element 31 has an elastic nozzle portion 311 in contact with the air exhaust assembly 32, which provides the air exhaust assembly 32 with a micro-motion capability. Specifically, the suction element 31 is a rubber suction nozzle in the present embodiment.
[0042] With reference to Figure 5 and Figure 6 , the exhaust assembly 32 comprises a connecting member adsorbed to the suction member 31 and a first plate member 321 connected to the connecting member, the first plate member 321 is arranged transversely, an exhaust passage 33 capable of exhausting but not allowing the rubber material to pass through is formed on the first plate member 321 and between the first plate member 321 and the connecting member, and an air cavity 34 is also formed between the first plate member 321 and the connecting member, and a material passing passage 3211 is arranged at the middle position of the first plate member 321.
[0043] With reference to Figure 5 and Figure 6 , the connecting member comprises a second plate member 35, the second plate member 35 is arranged in parallel with the first plate member 321 and above the first plate member 321, the air cavity 34 is formed between the first plate member 321 and the second plate member 35, and the air cavity 34 is communicated with the suction member 31; the second plate member 35 is provided with a connecting structure 36, the suction member 31 is adsorbed to the connecting structure 36, the connecting structure 36 provides a precise and firm mounting adsorption site for the suction member 31 and ensures the sealing of the communication between the suction member 31 and the air cavity 34. The second plate member 35 is connected with a sealing ring 37, the sealing ring 37 has elastic deformation ability, the connecting structure 36 is located in the sealing ring 37, the diameter of the sealing ring 37 gradually decreases towards the bottom end of the storage barrel 5, and the connecting structure 36 is located in the sealing ring 37. Figure 3 When the sealing ring 37 enters the storage barrel 5, at least part of the outer wall of the sealing ring 37 will be matched with the inner wall of the storage barrel 5 to form a closed space in the area below the sealing ring 37 in the storage barrel 5, in addition, the tapered design will form a natural guide when the sealing ring 37 is loaded into the storage barrel, reducing the entry resistance.
[0044] With reference to Figure 5 and Figure 6 , the connecting structure 36 comprises a ventilation head 361 connected to the first plate member 321 and a ventilation plug 362 installed in the ventilation head 361, the suction member 31 is adsorbed and fixed to the ventilation head 361, the ventilation plug 362 is made of sponge, and the ventilation plug 362 is plugged into the ventilation head 361 by using its elastic deformation ability.
[0045] With reference to Figure 5 , a clamping groove 38 is formed between the ventilation head 361 and the sealing ring 37, and Figure 2 , the mounting member 24 is clamped in the clamping groove 38, so that the position reliability of the connecting member in the application is guaranteed by the suction member 31 on one hand and by the clamping cooperation of the clamping groove 38 and the mounting member 24 on the other hand.
[0046] With reference to Figure 5 and Figure 6The exhaust passage 33 includes an exhaust ring groove 331 and a plurality of exhaust holes 332. The exhaust ring groove 331 is provided with two, one of which is formed between the first plate 321 outer periphery and the sealing ring 37, and the other is formed between the discharge pipe 22 and the material passage 3211. The plurality of exhaust holes 332 are uniformly distributed on the first plate 321.
[0047] After the first plate 321 enters the glue storage barrel 5, at least part of the sealing ring 37 will be attached to the inner wall of the glue storage barrel 5. As the exhaust assembly 32 moves downward, the air in the glue storage barrel 5 will enter the air cavity 34 through the exhaust ring groove 331 and the plurality of exhaust holes 332 and then be sucked out by the suction piece 31, thereby achieving the exhaust of the glue storage barrel 5. After the first plate 321 moves to press the glue, the air that may be carried in the glue will be pressed out and also enter the air cavity 34 from the exhaust ring groove 331 and the plurality of exhaust holes 332, thereby achieving the exhaust of the glue.
[0048] It should be noted that when the first plate 321 applies pressure to the glue, the free volume of the glue is compressed, and the tiny air bubbles originally dissolved or dispersed in the glue will gather into larger air bubbles under the action of pressure. At the same time, the pressure will drive the air bubbles to migrate to the low-pressure area of the glue, such as the surface of the glue, and eventually escape the surface of the glue and enter the exhaust hole 332 after being separated. In addition, due to the design of the elastic nozzle part 311 in the present application, the first plate 321 has a micro-motion capability, which can slow down the pressing speed and then return to the original position, which can give the air bubbles enough time to migrate to the surface and reduce the probability of being wrapped by the glue.
[0049] After the suction piece 31 is released from the suction fixing of the connecting member, the connecting member and the first plate 321 can be disassembled. Other types of connecting members and first plate 321 styles can adapt to different sizes of storage barrels and different viscosities of glue. For example, compared with high-viscosity glue, low-viscosity glue needs to be designed with smaller diameter exhaust holes 332 to prevent it from entering the air cavity 34 through the exhaust passage 33.
[0050] The air vent head 361 provides a directional channel for air flow, ensuring that the air in the air cavity 34 can flow accurately and smoothly to the suction piece 31. The air vent plug 362 type can be flexibly selected according to the actual working conditions such as glue viscosity and air content, to achieve controllable adjustment of the exhaust flow. For example, for high-viscosity glue, a small-diameter air vent plug 362 can be selected, so that the amount of air flowing through the air vent plug 362 at the same time is limited, avoiding excessive negative pressure that causes the glue to be sucked into the air cavity 34 through the exhaust passage 33.
[0051] The exhaust ring groove 331 between the outer periphery of the first plate member 321 and the connecting member forms a ring-shaped main exhaust passage 33 in cooperation with the plurality of exhaust holes 332 uniformly distributed on the first plate member 321, and an efficient exhaust system of multi-point suction and ring-shaped exhaust is constructed. The plurality of uniformly distributed exhaust holes 332 can suck from different areas in the glue storage barrel 5, ensuring uniformity of exhaust, avoiding local air residue, and the plurality of uniformly distributed exhaust holes 332 also facilitate subsequent reception of bubbles floating to the surface of the rubber compound; the exhaust ring groove 331 realizes the centralized export of air in the glue storage cylinder, shortens the exhaust path, and increases the exhaust flux, and the two work together to further improve the exhaust efficiency, ensure that the air in the rubber compound is completely exhausted, and ensure that the rubber compound is bubble-free during transportation.
[0052] Referring to Figure 6 and Figure 7 , the connecting member further comprises a shunt assembly 363 connected to the second plate member 35, and the shunt assembly 363 is located in the air cavity 34; specifically, the shunt assembly 363 comprises a plurality of shunt plates 3631, the shunt plates 3631 are vertically arranged, and the plurality of shunt plates 3631 are distributed in the circumferential direction, each shunt plate 3631 has an air passage 3632, and each shunt plate 3631 has a clamping block 3633, and the first plate member 321 has a clamping hole 3212 corresponding to each shunt plate 3631, and the clamping block 3633 is clamped in the clamping hole 3212. Therefore, in the present application, the first plate member 321 can also be replaced separately.
[0053] The plurality of shunt plates 3631 can guide and shunt the air in the air cavity 34, break the phenomenon of local accumulation of air in the air cavity 34, and make the air uniformly distributed and quickly converge to the exhaust passage 33, thereby significantly improving the exhaust efficiency.
[0054] The implementation principle of a two-component screw type pressure disc pump in an embodiment of the present application is as follows: After the rubber compound is stored in the glue storage barrel 5, the pressure driving member 11 drives the first plate member 321 to enter the glue storage barrel 5, at least part of the sealing ring 37 will be attached to the inner wall of the glue storage barrel 5, at this time, as the first plate member 321 moves downward, the air in the glue storage barrel 5 will enter the air cavity 34 through the exhaust ring groove 331 and the plurality of exhaust holes 332 and then be sucked away by the suction member 31, thereby realizing the exhaust of the glue storage barrel 5, and after the first plate member 321 moves to press the rubber compound, the air possibly carried in the rubber compound will be pressed out and also enter the air cavity 34 from the exhaust ring groove 331 and the plurality of exhaust holes 332, thereby realizing the exhaust of the rubber compound; then, the continuous pressing of the first plate member 321 will make the rubber compound enter the discharge pipe 22, at this time, the driving driving member 23 drives the screw to rotate, thereby making the rubber compound transported to the flexible pipe 222 and then discharged.
[0055] The embodiments of the present application are preferred embodiments of the present application, and do not limit the protection scope of the present application, and therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
