Description

Technical Field

[0001] This application relates to the field of dispensing machine technology, and in particular to a high-efficiency dispensing machine for vacuum environments. Background Technology

[0002] Today, with the rapid development of manufacturing fields such as automotive electronics, capacitor coils, new energy, and electronic engineering, the requirements for product sealing, anti-interference, and service life are constantly increasing. Vacuum potting technology has become the core process to ensure the potting quality of such products (such as automotive sensors, new energy battery modules, and precision circuit boards) because it can effectively prevent air from mixing into the adhesive and forming bubbles. As a result, potting machines in a vacuum environment have become key equipment in the product potting process.

[0003] In existing technologies, traditional vacuum dispensing machines typically employ a single-station, door-opening design for material feeding and discharging. Each time a product to be dispensed or a dispensed product is removed, the machine door must be opened to disrupt the vacuum environment inside the machine. After the material feeding and discharging operations are completed, the door must be closed again and the vacuum pump must be restarted to re-evacuate the vacuum. This operating mode requires vacuuming once after material feeding and once after material discharging, which not only leads to frequent vacuum disruptions inside the machine and repeated consumption of vacuum building time, but also prolongs the interruption time of dispensing operations. Especially in mass production scenarios, frequent vacuum disruptions can significantly extend the work cycle, making it difficult to improve production efficiency.

[0004] Therefore, we propose a high-efficiency dispensing machine for vacuum environments to solve the above problems. Utility Model Content

[0027] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] See Figures 1-5 This application provides a high-efficiency dispensing machine under vacuum conditions, including a chassis 1. Support legs 2 are fixedly installed at each of the four corners of the chassis 1's bottom. A vacuum pump 7 is fixedly installed on the right outer wall of the chassis 1. An air suction pipe 8 is fixedly connected to the suction end of the vacuum pump 7, with one end of the suction pipe 8 extending into the chassis 1. A one-way valve is fixedly installed inside the suction pipe 8. A vacuum pressure gauge 9 is fixedly installed on the right outer wall of the chassis 1. By controlling the operation of the vacuum pump 7, air can be extracted from the chassis 1 through the suction pipe 8, creating a sealed vacuum space inside the chassis 1. The vacuum pressure gauge 9 monitors the vacuum level inside the chassis 1 in real time, ensuring that the dispensing process is always conducted in a stable vacuum environment. In this system, air is effectively prevented from mixing into the adhesive and forming bubbles. The one-way valve effectively prevents external air from flowing back into the housing 1, maintaining a stable vacuum level inside the housing 1 and ensuring the continuity and reliability of the vacuum environment. The housing 1 is equipped with an adhesive dispensing mechanism 3 and a feeding / discharging mechanism 4. The feeding / discharging mechanism 4 is used to control the insertion and removal of products. The feeding / discharging mechanism 4 includes a support base 41, a hydraulic cylinder 42, a crossbeam 43, an upper sealing plate 44, an upper U-shaped seat 45, a middle sealing plate 46, a lower U-shaped seat 47, a lower sealing plate 48, and two clamping and positioning assemblies. The support base 41 is fixedly installed on the left outer wall of the housing 1, and the hydraulic cylinder 42 is fixedly installed on the top of the support base 41 and is vertically arranged. Figures 1-3As shown, hydraulic cylinder 42 is in an extended state. A crossbeam 43 is fixedly installed on the output shaft end of hydraulic cylinder 42 and located above the housing 1. An upper sealing plate 44 is fixedly installed on the bottom of the crossbeam 43. An upper U-shaped seat 45 is fixedly installed on the bottom of the upper sealing plate 44. The top of the housing 1 has an upper through hole 5, through which the bottom of the upper U-shaped seat 45 passes. An intermediate sealing plate 46 is fixedly installed on the bottom of the upper U-shaped seat 45, sealingly fitting against the inner top wall of the housing 1. A lower U-shaped seat 47 is fixedly installed on the bottom of the intermediate sealing plate 46. The bottom of the housing 1 has a lower through hole 6. The bottom of the lower U-shaped seat 47 has a through hole 6. The lower sealing plate 48 is fixedly installed at the bottom of the lower U-shaped seat 47. The lower sealing plate 48 is sealed and fitted to the bottom of the housing 1. A three-layer sealing structure consisting of the upper sealing plate 44, the middle sealing plate 46, and the lower sealing plate 48, along with the upper U-shaped seat 45 and the lower U-shaped seat 47 passing through the upper through hole 5 and the lower through hole 6 of the housing 1 respectively, is used. When the hydraulic cylinder 42 drives the upper U-shaped seat 45 and the lower U-shaped seat 47 to rise to achieve product entry and exit, the upper U-shaped seat 45 moves out of the housing 1, and the lower U-shaped seat 47 and the product clamped and fixed inside it enter the housing 1. The middle sealing plate 46... The upper sealing plate 44 seals the upper through hole 5, and the lower sealing plate 48 seals the lower through hole 6, effectively preventing vacuum leakage. This facilitates the potting process of the product clamped and fixed in the lower U-shaped seat 47, and also makes it easy for operators to remove the potted product from the upper U-shaped seat 45. When the hydraulic cylinder 42 drives the upper U-shaped seat 45 and the lower U-shaped seat 47 to descend and realize the product entry and exit, at this time, the lower U-shaped seat 47 moves out of the machine housing 1, and the upper U-shaped seat 45 and the product clamped and fixed inside it enter the machine housing 1. The upper sealing plate 44 seals the upper through hole 5, and the middle sealing plate 46 seals the lower through hole 6, effectively preventing vacuum leakage. This design facilitates the gluing process on products clamped and fixed within the upper U-shaped seat 45, and also allows operators to easily remove products that have undergone gluing on the lower U-shaped seat 47. Consequently, the vacuum inside the chassis 1 is only broken once during product insertion and removal. Furthermore, the alternating use of the upper U-shaped seat 45 and the lower U-shaped seat 47 creates a dual-station gluing process, reducing waiting time and enhancing the continuity of the gluing operation. This effectively solves the problems of frequent vacuum disruptions during product insertion and removal in a vacuum environment, as well as the lack of continuity in the gluing process, significantly shortening the work cycle and improving work efficiency.

[0029] In this embodiment, two clamping and positioning components are respectively installed on the upper U-shaped seat 45 and the lower U-shaped seat 47. The clamping and positioning components are used to clamp and fix the product. Two symmetrically distributed pads 49 are fixedly installed on the bottom inner wall of the upper U-shaped seat 45 and the bottom inner wall of the lower U-shaped seat 47. Both clamping and positioning components include two electric telescopic rods 410 and two clamping plates 411. The electric telescopic rods 410 are fixedly installed on the corresponding pads 49, and the clamping plates 411 are fixedly installed on the output shaft end of the electric telescopic rods 410. The electric telescopic rods 410 are used to control the linear movement of the clamping plates 411. By utilizing the cooperative action of the two clamping plates 411 on the upper U-shaped seat 45, the product can be clamped and fixed in the upper U-shaped seat 45. By utilizing the cooperative action of the two clamping plates 411 on the lower U-shaped seat 47, the product can be clamped and fixed in the lower U-shaped seat 47, thereby avoiding product displacement during the glue dispensing process and causing glue dispensing deviation.

[0030] In this embodiment, the cross-sectional dimension of the upper sealing plate 44 is larger than that of the upper through hole 5, and the cross-sectional dimension of the upper through hole 5 is larger than that of the upper U-shaped seat 45. The upper sealing plate 44, the middle sealing plate 46 and the lower sealing plate 48 have the same shape and size, and the upper U-shaped seat 45 and the lower U-shaped seat 47 have the same shape and size. This not only ensures the smoothness of the upper U-shaped seat 45 and the lower U-shaped seat 47 entering the chassis 1, but also ensures the effectiveness of sealing the upper through hole 5 and the lower through hole 6.

[0031] In this embodiment, the glue dispensing mechanism 3 is used for glue dispensing processing of the product. The glue dispensing mechanism 3 includes two glue storage cylinders 31, two glue outlet pipes 32, two glue metering pumps 33, two glue delivery hoses 34, a second hydraulic cylinder 35, an L-shaped plate 36, a second electric telescopic rod 37, a dual-glue mixing valve 38, and a glue dispensing head 39. The two glue storage cylinders 31 are fixedly installed on the top of the housing 1. The two glue storage cylinders 31 are used to hold two-component glue solutions (such as glue A and glue B) respectively, which are adapted to the dual-glue mixing and potting requirements. The two glue outlet pipes 32 are respectively fixedly connected to the bottom of the corresponding glue storage cylinders 31. The two glue metering pumps 33 are both fixedly installed on the top inner wall of the housing 1. One end of the two glue outlet pipes 32 is fixedly connected to the suction end of the corresponding glue metering pump 33. The two glue delivery hoses 34 are respectively fixedly connected to the discharge end of the corresponding glue metering pump 33. The second hydraulic cylinder 35 is fixedly installed on the right inner wall of the housing 1 and is arranged horizontally. The L-shaped plate 36 is fixedly installed on the output shaft of the second hydraulic cylinder 35. At one end, the electric telescopic rod 37 is fixedly installed on the top inner wall of the L-shaped plate 36. The dual-adhesive mixing valve 38 is fixedly installed on the output shaft end of the electric telescopic rod 37. The dual-adhesive mixing valve 38 is provided with one glue outlet port and two glue inlet ports. One end of each of the two glue delivery hoses 34 is fixedly connected to the two glue inlet ports of the dual-adhesive mixing valve 38. The dispensing head 39 is fixedly connected to the glue outlet port of the dual-adhesive mixing valve 38. Using two glue metering pumps 33, two kinds of glue can be pumped separately, and the glue output of the two kinds of glue can be precisely controlled. The two kinds of glue are then transported to the dual-adhesive mixing valve 38 through the two glue delivery hoses 34 for uniform mixing. Finally, the uniformly mixed dual glue is discharged from the dispensing head 39 for glue dispensing processing of products. The water position of the dispensing head 39 can be adjusted by the hydraulic cylinder 35, and the height position of the dispensing head 39 can be adjusted by the electric telescopic rod 37. The dispensing position can be flexibly adjusted to adapt to products of different sizes and dispensing points.

[0032] In this embodiment, the top of the L-shaped plate 36 is provided with a clearance hole 310, and both glue delivery hoses 34 pass through the clearance hole 310. When adjusting the position of the glue dispensing head 39, it will not be obstructed by the two glue delivery hoses 34.

[0033] In this embodiment, an L-shaped support rod 311 located below the hydraulic cylinder 35 is fixedly installed on the right side of the L-shaped plate 36. The bottom end of the L-shaped support rod 311 slides against the bottom inner wall of the housing 1, and the right side of the L-shaped support rod 311 abuts against the right inner wall of the housing 1. The design of the L-shaped support rod 311 enhances the stability of the L-shaped plate 36 during movement.

[0034] In this embodiment, a vacuum pump 312 is fixedly installed on the top of the glue storage cylinder 31. A suction pipe 313 is fixedly connected to the suction end of the vacuum pump 312. A one-way valve is fixedly installed inside the suction pipe 313. One end of the suction pipe 313 extends into the glue storage cylinder 31. A vacuum pressure gauge 314 is fixedly installed on the left side of the glue storage cylinder 31. The design of the one-way valve can effectively prevent external air from flowing back into the glue storage cylinder 31, avoid the vacuum level in the glue storage cylinder 31 from decreasing due to backflow, ensure the continuity and reliability of the vacuum environment, and provide a stable foundation for high-precision glue dispensing.

[0035] In this embodiment, a motor 315 is fixedly installed at the top center of the glue storage cylinder 31. The output shaft of the motor 315 extends into the glue storage cylinder 31 and is fixedly installed with a stirring rod 316. Multiple uniformly distributed stirring paddles 317 are fixedly installed on the stirring rod 316. The motor 315 is used to drive the stirring rod 316 and the stirring paddles 317 to rotate, which can stir the glue liquid in the glue storage cylinder 31, avoid the glue liquid from settling and layering due to long-term standing, ensure uniform glue liquid concentration, and reduce glue dispensing quality problems caused by uneven glue liquid from the source. A feeding hole is opened at the top of the glue storage cylinder 31, and a stopcock 318 is fixedly installed in the feeding hole. The design of the stopcock 318 and the feeding hole facilitates the replenishment of glue liquid into the glue storage cylinder 31.

[0036] In this embodiment, an observation port is provided on the front side wall of the chassis 1, and a transparent observation mirror 10 is fixedly installed in the observation port. The design of the transparent observation mirror 10 and the observation port allows for real-time observation of the potting process inside the chassis 1, so as to promptly detect any abnormalities. The transparent observation mirror 10 is made of transparent tempered glass, which has the advantages of good light transmission and durability.

[0037] In this embodiment, it should be noted that the vacuum pump 7, adhesive metering pump 33, hydraulic cylinder 35, electric telescopic rod 37, dual adhesive mixing valve 38, vacuum pump 312, motor 315, hydraulic cylinder 42, and electric telescopic rod 410 are all commercially available. Their wiring connection and control methods are mature technologies in the field and have been fully disclosed, so they will not be described in detail here. Manually or electrically controlled vacuum breaking valves (not shown in this article, but are conventional technical means in the field) are installed on both the housing 1 and the adhesive storage cylinder 31 to break the vacuum in the housing 1 and the adhesive storage cylinder 31 respectively according to the usage requirements.

[0038] Based on the above structure, the working principle of the high-efficiency dispensing machine in a vacuum environment provided in this application is as follows:

[0039] Before the glue dispensing operation, pour different types of glue (e.g., glue A and glue B) into the two glue storage cylinders 31 respectively. Then, start the vacuum pump 312 at the top of the two glue storage cylinders 31 and extract the air from the glue storage cylinders 31 through the suction pipe 313. With the help of the vacuum pressure gauge 314, an independent vacuum environment is formed in the glue storage cylinders 31. This can remove the air dissolved in the glue in the glue storage cylinders 31. Doing a good job of preparation before the operation helps to reduce the probability of air bubbles being generated during the subsequent glue dispensing process.

[0040] When starting the glue-dispensing operation, first, take a product to be dispensed and place it between the two clamping plates 411 on the inner bottom wall of the upper U-shaped seat 45. Then, control the extension of the two electric telescopic rods 410 on the inner bottom wall of the upper U-shaped seat 45, so that the two clamping plates 411 move closer to each other, thus clamping and fixing the product. After the product is clamped and fixed, control the retraction and reset of the hydraulic cylinder 42 to control the vertical descent of the crossbeam 43. The crossbeam 43 drives the upper U-shaped seat 45 to descend vertically. The sealing plate 44, upper U-shaped seat 45, middle sealing plate 46, lower U-shaped seat 47 and lower sealing plate 48 descend vertically. The upper U-shaped seat 45 and the product clamped and fixed inside it gradually enter the machine box 1. The lower U-shaped seat 47 gradually moves downward and out of the machine box 1. When the upper sealing plate 44 descends and presses against the top surface of the machine box 1, the operation of hydraulic cylinder 42 stops. At this time, the upper sealing plate 44 completely seals and covers the upper through hole 5, and the middle sealing plate 46 completely seals and covers the lower through hole 6.

[0041] Next, control the operation of vacuum pump 7 to extract air from the casing 1 through suction pipe 8. During the extraction process, the vacuum level in the casing 1 can be monitored in real time by observing vacuum pressure gauge 9. When the preset vacuum value is reached in the casing 1, stop the operation of vacuum pump 7.

[0042] After vacuuming is completed, according to the size of the product to be glued and the glued position in the machine box 1, the hydraulic cylinder 2 35 is controlled to extend and run. Its output shaft drives the L-shaped plate 36 to move laterally, thereby adjusting the horizontal position of the electric telescopic rod 2 37, the dual glue mixing valve 38 and the glued head 39 on the L-shaped plate. Then, the electric telescopic rod 2 37 is started, and its output shaft drives the dual glue mixing valve 38 and the glued head 39 to rise and fall vertically, so that the glued head 39 can be adjusted to be aligned with the glued position of the product.

[0043] After the alignment point of the dispensing head 39 is adjusted, the two glue metering pumps 33 are controlled to run, and the dual glue mixing valve 38 is started. At this time, the glue in the two glue storage cylinders 31 enters the suction end of the corresponding glue metering pump 33 through the glue outlet pipe 32 at the bottom of each cylinder. The glue metering pump 33 accurately controls the glue output according to the preset dosage (the preset dosage can be adjusted by professionals according to the glue dispensing requirements of the product). Then, it is delivered to the dual glue mixing valve 38 through the corresponding glue delivery hose 34, so that the two glues can be evenly mixed in the dual glue mixing valve 38. Then, the mixed glue flows into the dispensing head 39, which can be accurately poured into the potting area of ​​the product.

[0044] During the process of applying glue to the product inside the chassis 1, the operator can take another product to be glued and place it between the two clamps 411 on the bottom inner wall of the lower U-shaped seat 47. Then, control the two electric telescopic rods 410 on the bottom inner wall of the lower U-shaped seat 47 to extend and move, so that the two clamps 411 move closer to each other. The product can then be clamped and fixed by the two clamps 411, thus completing the preparation work before applying glue.

[0045] After the product is filled with adhesive inside the housing 1, stop the operation of the two adhesive metering pumps 33, and control the hydraulic cylinder 35 and the electric telescopic rod 37 to retract and reset, thereby controlling the dispensing head 39 to return to its initial position. Then, control the hydraulic cylinder 42 to extend, thereby controlling the crossbeam 43 to rise vertically. The crossbeam 43 drives the upper sealing plate 44, upper U-shaped seat 45, middle sealing plate 46, lower U-shaped seat 47, and lower sealing plate 48 to rise vertically. The upper U-shaped seat 45 and the filled product inside it gradually rise and move out of the housing 1, while the lower U-shaped seat 47 and the product clamped and fixed inside it gradually rise and enter the housing 1. When the middle sealing plate 46 rises and presses tightly against the top surface of the housing 1, stop. When hydraulic cylinder 42 is in operation, the middle sealing plate 46 completely seals and covers the upper through hole 5, and the lower sealing plate 48 completely seals and covers the lower through hole 6. At this time, the vacuum level in the machine box 1 is judged by observing the vacuum pressure gauge 9. The vacuum pump 7 is controlled to run once to extract the air in the machine box 1 until the vacuum level in the machine box 1 is extracted to the specified range. Then, the hydraulic cylinder 35 is extended and the electric telescopic rod 37 is operated again to adjust the glue dispensing head 39 to the glue dispensing point of the product in the machine box 1. Then, the two glue metering pumps 33 and the double glue mixing valve 38 are operated again to perform glue dispensing processing on the product clamped and fixed in the lower U-shaped seat 47.

[0046] During the glue-filling process of the product clamped and fixed in the lower U-shaped seat 47, the operator takes a product to be glued and places it between two clamping plates 411 on the inner wall of the bottom of the upper U-shaped seat 45. Then, the operator controls the two electric telescopic rods 410 on the inner wall of the bottom of the upper U-shaped seat 45 to extend and move, so that the product can be clamped and fixed by the two clamping plates 411. This completes the preparation work before glue filling. By following the above operation steps and using the alternating use of the upper U-shaped seat 45 and the lower U-shaped seat 47, a dual-station glue filling process is formed, which reduces the waiting time for glue filling operations, enhances the continuity of the glue filling operation, and ensures that the vacuum degree inside the machine box 1 is only broken once during the product removal and placement process. This effectively solves the problem of frequent breaking of the vacuum degree inside the machine box 1 and the discontinuity of glue filling operations when products are placed and removed in a vacuum environment, greatly shortens the operation cycle, and improves work efficiency.
