Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensers, in particular to a quantitative glue dispenser. Background Art

[0002] A quantitative glue dispenser is an automated device used to accurately dispense a specific volume or weight of glue. This equipment is very useful in industrial production, especially in electronic manufacturing, adhesive production, and laboratory research, because it can improve the quality and consistency of products while reducing the need for manual operation. This equipment usually includes a control system for setting the required volume or weight of glue, a metering system for accurately dispensing glue, and a delivery system to deliver the dispensed glue into a loading tube.

[0003] When delivering glue to the loading tube, the glue needs to be injected from the bottom of the loading tube. This is because injecting from the bottom can reduce the chance of glue contacting with air, thereby reducing the generation of bubbles. Bubbles may form in the glue and cause uneven filling or voids, affecting the quality of the product. Injecting glue from the bottom can ensure that the long tube is filled evenly, avoiding the top being filled first and leaving an unfilled area at the bottom. Therefore, in order to be able to inject glue from the bottom of the carrier tube, a longer guide tube needs to be set so that the guide tube can extend to the bottom of the carrier tube. However, the glue is easy to adhere to the inside of the guide tube, and the length of the guide tube is long. This results in that after the filling is completed, when the transfer to the guide tube is stopped, the glue in the guide tube will slowly flow downward. In order to ensure work efficiency, it is impossible to wait for a long time for the glue in the guide tube to drip naturally into the carrier tube. The carrier tube needs to be taken out quickly. If the carrier tube is taken out, the glue is easy to drip onto the workbench, causing waste, and the glue in the guide tube cannot be completely entered into the carrier tube. Utility Model Content

[0004] The utility model aims to solve the problem mentioned in the background technology that the glue in the guide tube will slowly flow downwards and the glue will easily drip onto the workbench when the carrying tube is taken out, and proposes a quantitative glue dispenser that can quickly discharge the glue in the guide tube.

[0006] A flow guide pipe fixedly mounted on the feeding device;

[0007] The anti-drip mechanism is installed on the base and inside the flow guide tube, and the anti-drip mechanism scrapes off the glue adhered in the flow guide tube.

[0009] Optionally, the anti-drip mechanism includes a delivery pipe fixedly mounted on the stop valve, the delivery pipe is located inside the guide pipe, the length of the delivery pipe is smaller than the guide pipe, a slider is slidably mounted inside the guide pipe, a first magnet is fixedly mounted on the slider, a driving block is slidably mounted outside the guide pipe, a plurality of second magnets are fixedly mounted on the driving block, a first push rod motor is fixedly mounted on the base, and the output shaft of the first push rod motor is fixedly connected to the driving block.

[0010] Optionally, the driving block is provided with a through hole for allowing the conveying pipe to pass through, and the sliding block is provided with a blocking mechanism, and the blocking mechanism blocks the through hole.

[0011] Optionally, the blocking mechanism includes a mounting groove arranged at the bottom of the slider, a plurality of blocking plates rotatably installed in the mounting groove, a limiting rod fixedly installed in the mounting groove, and a return spring fixedly installed in the mounting groove, and the other end of the return spring is fixedly connected to the blocking plate.

[0028] Example

[0029] like Figure 1 As shown, a quantitative glue dispenser proposed by the utility model comprises a base 1, a feeding device mounted on the base 1, and a guide tube 5 fixedly mounted on the feeding device. The feeding device comprises a barrel 2 fixedly mounted on the base 1, a metering pump 201, and a stop valve 202, the input end of the metering pump 201 is fixedly connected to the barrel 2, the output end of the metering pump 201 is fixedly connected to the stop valve 202, and the guide tube 5 is fixedly mounted on the stop valve 202. The barrel 2 is used to hold glue, and the metering pump 201 can control the flow rate and pressure very accurately, and the error is usually within a very small range. The glue is transported to the stop valve 202 by the metering pump 201, and the glue can enter the guide tube 5 by opening the stop valve 202.

[0030] like Figure 2-6As shown, the quantitative glue dispenser also includes an anti-drip mechanism, which is installed on the base 1 and inside the guide tube 5. The anti-drip mechanism scrapes off the glue adhering to the guide tube 5. The anti-drip mechanism includes a delivery tube 6 fixedly installed on the stop valve 202, the delivery tube 6 is located inside the guide tube 5, the length of the delivery tube 6 is smaller than the guide tube 5, a slider 601 is slidably installed inside the guide tube 5, a first magnet 602 is fixedly installed on the slider 601, a driving block 603 is slidably installed outside the guide tube 5, a plurality of second magnets 604 are fixedly installed on the driving block 603, a first push rod motor 606 is fixedly installed on the base 1, and the output shaft of the first push rod motor 606 is fixedly connected to the driving block 603. The glue passing through the stop valve 202 will enter the delivery tube 6, and enter the guide tube 5 through the delivery tube 6. At this time, the slider 601 is located on the upper side of the delivery tube 6. When the glue is transported, a large amount of glue will adhere to the inner wall of the guide tube 5. Since the length of the conveying tube 6 is short, it is not easy for glue to remain inside the conveying tube 6. At this time, the first push rod motor 606 is started to drive the driving block 603 to move downward. Since the first magnet 602 and the second magnet 604 attract each other, the movement of the second magnet 604 can drive the first magnet 602 to move, and then drive the slider 601 to move downward. Since the slider 601 is in contact with the inner wall of the guide tube 5. The glue on the inner wall of the guide tube 5 can be scraped off by the movement of the slider 601, and the glue adhering to the guide tube 5 can be quickly moved downward, so that the glue on the inner wall of the guide tube 5 can be quickly flowed out of the guide tube 5. The problem of glue dripping on the workbench is prevented.

[0031] Furthermore, the driving block 603 is provided with a through hole 605 for the conveying pipe 6 to pass through, and the slider 601 is provided with a blocking mechanism, which blocks the through hole 605. The blocking mechanism includes a mounting groove 607 provided at the bottom of the slider 601, a plurality of blocking plates 608 rotatably mounted in the mounting groove 607, a limit rod 609 fixedly mounted in the mounting groove 607, and a return spring 610 fixedly mounted in the mounting groove 607, and the other end of the return spring 610 is fixedly connected to the blocking plate 608. When the slider 601 moves upward, the conveying pipe 6 will pass through the through hole 605 and apply resistance to the blocking plate 608. As the blocking plate 608 continues to rise, the blocking plate 608 will flip on the slider 601. Thus, the return spring 610 is stretched at this time. When the slider 601 moves downward and passes through the delivery pipe 6, the blocking plate 608 can rotate under the action of the return spring 610, so that the blocking plate 608 blocks the through hole. This prevents the glue from entering the upper side of the slider 601 through the through hole 605. This can effectively ensure that the glue in the guide pipe 5 can be completely discharged. And under the limiting action of the limiting rod 609 on the blocking plate 608, the blocking plate 608 can be prevented from rotating in the opposite direction. This can ensure the tightness of the blocking plate 608 blocking the through hole 605.

[0032] like Figure 1 As shown, a clamping mechanism is installed on the base 1, and the clamping mechanism includes a slide 3 provided on the base 1, a mounting seat 301 slidably mounted in the slide 3, and a clamping claw motor 302 fixedly mounted on the mounting seat 301, and the loading tube 4 is clamped on the clamping claw motor 302. The loading tube 4 can be clamped and fixed by the clamping claw motor 302. A second push rod motor 303 is fixedly mounted on the base 1, and the output shaft of the second push rod motor 303 is fixedly connected to the mounting seat 301. The mounting seat 301 can be driven to rise and fall by the second push rod motor 303, and then the loading tube 4 can be driven to rise and fall. The bottom of the loading tube 4 can be moved to the bottom of the guide tube 5 by the second push rod motor 303. And as the glue is gradually injected into the loading tube 4, the second push rod motor 303 drives the loading tube 4 to gradually descend. Thereby, the generation of bubbles can be prevented.

[0033] Working principle: The loading tube 4 can be clamped and fixed by the clamping claw motor 302. The mounting seat 301 can be driven to rise and fall by the second push rod motor 303, thereby driving the loading tube 4 to rise and fall. The bottom of the loading tube 4 can be moved to the bottom of the guide tube 5 by the second push rod motor 303. The glue is transported to the stop valve 202 by the metering pump 201, and the glue can enter the guide tube 5 by opening the stop valve 202. The glue passing through the guide tube 5 will enter the inside of the loading tube 4. As the glue is gradually injected into the inside of the loading tube 4, the second push rod motor 303 drives the loading tube 4 to gradually descend. This can prevent the generation of bubbles. After loading is completed, the first push rod motor 606 is started to drive the drive block 603 to move downward. Since the first magnet 602 and the second magnet 604 attract each other, the movement of the second magnet 604 can drive the first magnet 602 to move, and then drive the slider 601 to move downward, so that the glue on the inner wall of the guide tube 5 can be scraped off by the movement of the slider 601, and the glue adhering to the guide tube 5 can be quickly moved downward, so that the glue on the inner wall of the guide tube 5 can be quickly flowed out of the guide tube 5. The problem of glue dripping on the workbench is prevented.
