Description

Technical Field

[0001] This application relates to the field of dispensing machines, and more specifically, to a dispensing machine with a metering structure. Background Technology

[0002] Dispensing machines are commonly used for the mass encapsulation of electronic products and equipment. In particular, for the production of electronic components such as LEDs, dispensing machines can achieve highly accurate metering and mixing of two or more raw material liquids, and can accurately control the amount of liquid and glue dispensed. When encapsulating different electronic products, the amount of glue required for different products is different, which can easily lead to uneven dispensing. Too much or too little glue will have a certain impact on the later use of electronic equipment.

[0003] Chinese patent application CN202420429169.8 discloses a dispensing machine metering mechanism, which includes a base with four evenly spaced openings on the top. A glue tube is fixedly inserted into each of the four openings, with the bottom of the four glue tubes flush with the bottom of the base. The top of each of the four glue tubes is open, and a sealing plug is movably inserted into the top of each of the four glue tubes. A sleeve is fixedly installed on the top of the side wall of each of the four sealing plugs, and each sleeve is movably fitted onto the outside of the corresponding glue tube. A storage groove is provided on the top of each of the four sealing plugs, and a first hydraulic rod is fixedly installed in each of the four storage grooves. This invention allows the sleeves to move up and down by controlling the second hydraulic rod to drive the connecting frame, thus moving the sealing plugs between the sleeves up and down within the glue tube, thereby changing the internal capacity of the glue tube. Finally, controlling the first hydraulic rod to push the piston down within the glue tube enables dispensing of different quantities of glue.

[0004] The above solution has the following shortcomings: when in use, glue tends to get stuck at the dispensing nozzle and is not easy to scrape off in time. The accumulated residual glue tends to form hard lumps, which can cause blockage and affect the use of the dispensing machine. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a dispensing machine with a metering structure, which aims to improve the problem that glue tends to accumulate at the dispensing nozzle during use, making it difficult to remove in time. The residual glue tends to accumulate and form hard lumps, which can lead to blockage and affect the use of the dispensing machine.

[0006] This application provides a dispensing machine with a metering structure, including a dispensing structure and a cleaning structure. The dispensing structure includes a worktable, three glue cylinders, a U-shaped frame, and a dispensing assembly. The three glue cylinders are all fixedly connected to the worktable, and the U-shaped frame is fixedly connected to one side of the worktable. The dispensing assembly is connected to the U-shaped frame and fits against the inner wall of the glue cylinder. The cleaning structure includes three toothed plates, a linkage assembly, a dispensing pipe, and a scraper. The three toothed plates are all disposed on one side of the dispensing assembly and are slidably connected to the worktable. The linkage assembly is connected to the toothed plates, and the dispensing pipe is connected to the linkage assembly. The dispensing pipe is rotatably connected to one side of each of the three glue cylinders and communicates with the glue cylinder. The scraper is disposed inside the glue cylinder and fits against the inner wall of the dispensing pipe.

[0007] In one specific implementation, the glue-dispensing assembly includes a hydraulic cylinder, a lifting plate, a U-shaped plate, a connecting plate, and a piston. The hydraulic cylinder is installed on one side of the U-shaped frame. The lifting plate is fixedly connected to the movable end of the hydraulic cylinder and slidably connected to the U-shaped frame. The U-shaped plate is fixedly connected to one side of the lifting plate. The connecting plate is fixedly connected to the U-shaped plate and slidably connected to the glue cylinder. The piston is fixedly connected to one side of the connecting plate and fits against the inner wall of the glue cylinder.

[0008] In the above process, the hydraulic cylinder, lifting plate, U-shaped plate, connecting plate and piston can be set up to facilitate the synchronous dispensing of glue into the three glue cylinders.

[0009] In one specific implementation, sliders are fixedly connected to both sides of the lifting plate, and the U-shaped frame has a sliding groove, with the sliders slidably connected to the sliding groove.

[0010] In the above implementation process, the movement of the lifting plate can be easily limited by the sliding connection between the slider and the slide groove.

[0011] In one specific implementation, the linkage assembly includes two support plates, gears, a rotating shaft, a first bevel gear, and a second bevel gear. The two support plates are arranged parallel to each other on the bottom of the workbench. The gears are meshed on one side of each of the three gear plates. The gears are fixedly connected to the outer ring of the rotating shaft. The rotating shaft is rotatably connected to the support plates. The first bevel gear is fixedly connected to the outer ring of the rotating shaft. The second bevel gear is fixedly connected to the outer ring of the dispensing tube. The second bevel gear meshes with the first bevel gear.

[0012] In the above implementation process, the arrangement of two support plates, gears, rotating shafts, first bevel gears and second bevel gears makes it easy to rotate the glue tube during the glue dispensing process, so that the scraper can clean the glue residue on the inner wall of the glue tube and avoid blockage.

[0013] In one specific implementation, a sealed bearing is fixedly connected to the bottom of each of the three glue tubes, and the glue outlet tube is interference-fitted with the inner ring of the sealed bearing.

[0014] In the above process, by using an interference fit between the dispensing tube and the inner ring of the sealed bearing, the dispensing tube and the glue cylinder can be easily connected for rotation, while preventing glue leakage.

[0015] In one specific implementation, the bottom of each of the three glue tubes is connected to a glue inlet pipe, and the glue inlet pipe is equipped with a one-way valve.

[0016] In the above implementation process, the glue inlet tube facilitates glue injection, and the one-way valve in the glue inlet tube can easily prevent glue backflow during dispensing.

[0017] In one specific implementation, all three rubber tubes have graduation lines on their outer rings, and all three rubber tubes are transparent tubes.

[0018] In the above implementation process, by setting graduation lines on the outer ring of the glue tube, it is easy to measure and realize different amounts of glue dispensing.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: by setting up the glue dispensing component, it is convenient to dispense glue to the three glue tubes simultaneously, which improves the work efficiency. By using the three toothed plates and the linkage component, it is convenient to link the glue dispensing tube to rotate during the glue dispensing process, so that the scraper can clean the glue residue on the inner wall of the glue dispensing tube and avoid blockage.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Please see Figure 1 This application provides a dispensing machine with a metering structure, including a dispensing structure 10 and a cleaning structure 20.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The glue-dispensing structure 10 includes a workbench 110, three glue tubes 120, a U-shaped frame 130, and a glue-dispensing assembly 140. The three glue tubes 120 are all fixedly connected inside the workbench 110. The U-shaped frame 130 is fixedly connected to one side of the workbench 110. The glue-dispensing assembly 140 is connected to the U-shaped frame 130 and is attached to the inner wall of the glue tubes 120.

[0030] In a specific configuration, the glue-dispensing assembly 140 includes a hydraulic cylinder 141, a lifting plate 142, a U-shaped plate 143, a connecting plate 144, and a piston 145. The hydraulic cylinder 141 is installed on one side of the U-shaped frame 130. The lifting plate 142 is fixedly connected to the movable end of the hydraulic cylinder 141 and slidably connected to the U-shaped frame 130. The U-shaped plate 143 is fixedly connected to one side of the lifting plate 142. The connecting plate 144 is fixedly connected to the U-shaped plate 143 and slidably connected to the glue cylinder 120. The piston 145 is fixedly connected to one side of the connecting plate 144 and fits against the inner wall of the glue cylinder 120. The configuration of the hydraulic cylinder 141, lifting plate 142, U-shaped plate 143, connecting plate 144, and piston 145 facilitates simultaneous glue dispensing from the three glue cylinders 120.

[0031] In the specific setup, sliders 150 are fixedly connected to both sides of the lifting plate 142, and the U-shaped frame 130 is provided with a sliding groove. The sliders 150 are slidably connected to the sliding groove. The sliding connection between the sliders 150 and the sliding groove can conveniently limit the movement of the lifting plate 142.

[0032] In the specific setup, the bottom of each of the three glue tubes 120 is fixedly connected with a sealed bearing, and the glue outlet tube 230 is interference-fitted with the inner ring of the sealed bearing. The interference fit between the glue outlet tube 230 and the inner ring of the sealed bearing facilitates the rotational connection between the glue outlet tube 230 and the glue tube 120, while preventing glue leakage.

[0033] In the specific setup, the bottom of each of the three glue tubes 120 is connected to a glue inlet pipe 160. The glue inlet pipe 160 is equipped with a one-way valve. The glue inlet pipe 160 facilitates glue injection, and the one-way valve in the glue inlet pipe 160 can easily prevent glue backflow during glue dispensing.

[0034] In the specific setup, all three glue tubes 120 have scale lines on their outer rings. All three glue tubes 120 are transparent tubes. By setting scale lines on the outer rings of the glue tubes 120, it is easy to measure and achieve different amounts of glue dispensing.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The cleaning structure 20 includes three toothed plates 210, a linkage assembly 220, a dispensing tube 230, and a scraper 240. The three toothed plates 210 are all located on one side of the dispensing assembly 140 and are slidably connected to the worktable 110. The linkage assembly 220 is connected to the toothed plates 210, and the dispensing tube 230 is connected to the linkage assembly 220. The dispensing tube 230 is rotatably connected to one side of each of the three glue cylinders 120 and communicates with the glue cylinders 120. The scraper 240 is located inside the glue cylinders 120 and is in contact with the inner wall of the dispensing tube 230.

[0036] In a specific configuration, the linkage component 220 includes two support plates 221, a gear 222, a rotating shaft 223, a first bevel gear 224, and a second bevel gear 225. The two support plates 221 are arranged parallel to each other at the bottom of the workbench 110. Gears 222 are meshed on one side of each of the three toothed plates 210. The gears 222 are fixedly connected to the outer ring of the rotating shaft 223. The rotating shaft 223 is rotatably connected to the support plates 221. The first bevel gear 224 is fixedly connected to the outer ring of the rotating shaft 223. The second bevel gear 225 is fixedly connected to the outer ring of the glue dispensing tube 230 and meshes with the first bevel gear 224. The configuration of the two support plates 221, gear 222, rotating shaft 223, first bevel gear 224, and second bevel gear 225 facilitates the rotation of the glue dispensing tube 230 during the glue dispensing process, allowing the scraper 240 to clean the glue residue on the inner wall of the glue dispensing tube 230 and prevent clogging.

[0037] The working principle of this dispensing machine with a metering structure is as follows: When using the dispensing machine with a metering structure, the hydraulic cylinder 141 drives the lifting plate 142 to rise and fall along the slide groove of the U-shaped frame 130, which drives the U-shaped plate 143, the connecting plate 144, and the piston 145 to move synchronously. Metering is achieved by observing the scale line of the glue cylinder 120 and controlling the height of the piston 145. External glue is pumped into the glue cylinder 120 through the glue inlet pipe 160. During dispensing, the piston 145 descends and squeezes the glue, which is then discharged through the glue outlet pipe 230 at the bottom of the glue cylinder 120. Simultaneously, the lifting plate 142 drives the toothed plate 210 to move downward. The gear 222 meshes with the toothed plate 210, driving the rotating shaft 223 and the first bevel gear 224 to rotate. This, in turn, drives the dispensing tube 230 to rotate through the second bevel gear 225, causing the scraper 240 to clean the residual glue on the inner wall of the tube. When the piston 145 returns to its original position and rises, the toothed plate 210 moves in the opposite direction, causing the dispensing tube 230 to reverse and perform a secondary cleaning. This allows the scraper 240 to clean the glue residue on the inner wall of the dispensing tube 230, preventing blockage and completing the coordinated operation of dispensing and cleaning.

[0038] It should be noted that the specific model and specifications of the hydraulic cylinder 141 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0039] The power supply and principle of the hydraulic cylinder 141 are clear to those skilled in the art and will not be described in detail here.

[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
