Description

Technical Field

[0001] This application relates to the field of automation technology, and more specifically, to a glue dispensing mechanism. Background Technology

[0002] The application of adhesive tape is common in many industries, including advertising, automotive heating pads, woven bags, and cardboard boxes. Currently, the tape application process in these industries is done manually, which is inefficient. Existing tape application mechanisms often suffer from problems such as tape sticking to the mechanism during application, difficulty in measuring excess tape, and high costs.

[0003] The structure of the product can be referenced from the transmission positioning device disclosed in Chinese patent document 2014205757895. Although it achieves automatic glue dispensing function, there is still a problem that the glue is easily stuck to the mechanism during the dispensing process.

[0004] Currently, there is no adhesive dispensing mechanism that is convenient for dispensing adhesive and prevents it from sticking together. Summary of the Invention

This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a glue-dispensing mechanism, including:

[0007] Support device;

[0008] The tape pulling device includes a drive assembly and a tape clamping assembly. The tape clamping assembly is used to clamp one end of the tape and pull out a set length of tape under the drive of the drive assembly.

[0009] A tape-cutting device is used to cut the tape pulled out by the tape-pulling device.

[0010] Both the glue-pulling device and the glue-cutting device are fixed on the support device.

[0011] This application ensures that the tape can be stably stretched to a specified length through the action of the tape-pulling device; and through the action of the tape-cutting device, it ensures the neatness of the cut and ensures that each cut yields an extra piece of tape for the next clamping device to pick up; thus achieving an automated tape-picking effect.

[0012] Furthermore, the rubber cutting device includes a rubber cutting knife, a rubber cutting cylinder, a sliding block, a sliding cylinder, and a rubber cutting device base; the rubber cutting knife is fixed on the lifting rod of the rubber cutting cylinder, the rubber cutting cylinder is fixed on the sliding block, the sliding block is mounted on the piston rod of the sliding cylinder, and the sliding cylinder is fixed on the rubber clamping device base.

[0013] Furthermore, the base of the rubber cutting device is equipped with an air supply cylinder, a piston rod is provided at one end of the air supply cylinder, an air inlet and an air outlet are provided at one end of the air supply cylinder, a one-way valve is provided in the air inlet, and a first magnet is provided at the end of the piston rod that extends outward.

[0014] Furthermore, a limit plate is fixedly installed on one side of the rubber cutting cylinder. The limit plate has a first air blowing hole and a through hole. The through hole is connected to the first air blowing hole. One end of the through hole is connected to the air inlet through an air supply pipe. The rubber cutting blade has a second air blowing hole. The second air blowing hole is connected to the through hole through an air supply pipe. Several first air blowing holes and second air blowing holes are provided.

[0015] Furthermore, the adhesive clamping assembly includes an adhesive pulling base, an upper clamping plate, a mounting plate, a lower clamping plate, a clamping plate cylinder, and a second spring; the adhesive pulling base is moved under the control of the drive assembly, the mounting plate is fixed on the adhesive pulling base, the upper clamping plate is fixed on the mounting plate, the lower clamping plate is hinged on the mounting plate, the clamping plate cylinder is fixed on the adhesive pulling base, the lifting rod of the clamping plate cylinder abuts against the lower part of the lower clamping plate, and the second spring is installed between the upper part of the lower clamping plate and the mounting plate, and the lower clamping plate is L-shaped.

[0016] Furthermore, the laminated assembly includes a cylinder with a second magnet at one end.

[0017] Furthermore, the support device includes a base and a fixing seat; the fixing seat is set on the base, and the rubber cutting device, the drive assembly and the rubber clamping assembly are all installed on the base.

[0018] Furthermore, the drive assembly includes a servo motor, a drive belt, a synchronous pulley, a drive slider, and a drive rail; the servo motor drives the synchronous pulley, the drive belt is mounted on the synchronous pulley, the drive rail is mounted on the base, the drive slider is mounted on the drive rail, and the drive slider is fixedly connected to the drive belt.

[0020] Furthermore, the fixing base also includes a spring mounting hook, on which a first spring is provided, and the other end of the first spring is connected to the pressure plate mounting rod.

[0021] The beneficial effects of this application are as follows: When the adhesive pulling seat is reset, the second magnet on the adhesive pulling seat will contact the first magnet again, pushing the piston rod to slowly reset. When the piston rod resets, it will change the air pressure in the cylinder, squeezing the gas from the air outlet into the first through hole, and then blowing the gas through the first and second air blowing holes, thereby blowing the tape up, so that the tape can float between the upper and lower clamping plates, which is convenient for the upper and lower clamping plates to clamp it in the future, improving the efficiency of subsequent processing. At the same time, it eliminates the need for manual clamping and fixing of the tape, saving labor costs and improving the efficiency of automation. At the same time, blowing can prevent the tape from sticking to the limit block during the tape pulling process, further ensuring that the tape can be pulled stably. Attached Figure Description

[0037] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Reference Figure 1A glue-taking mechanism includes a support device, a glue-pulling device 2, and a glue-cutting device 3. The glue-pulling device 2 and the glue-cutting device 3 are respectively mounted on the support device. The support device includes a base 4 and a fixed seat 5. The fixed seat 5 is mounted on the base 4. The fixed seat 5 includes a material surplus detection sensor 6, a tape mounting shaft 7, a pressure plate 81 mounting rod 8, a limiting rod 82, and a spring mounting hook 9. The material surplus detection sensor 6 is mounted on the fixed seat 5. The material surplus detection sensor 6 is a diffuse reflection sensor, which is existing technology and will not be described in detail. It is used to detect the remaining amount of tape roll and issue a prompt. The tape roll mounting shaft is mounted on the fixed seat 5. The fixed seat 5 is also equipped with a pressure plate 81 mounting rod 8. The pressure plate 81 mounting rod 8 is equipped with a pressure plate 81 and a limiting rod 82. Under the action of the pressure plate 81 and the limiting rod 82, the tape is clamped and pressed, which facilitates subsequent cutting and ensures the flatness of the tape when it is stretched. At the same time, the limiting rod 82 can also limit the height of the tape.

[0039] Furthermore, the fixed base 5 is provided with a spring mounting hook 9, and the spring mounting hook 9 is provided with a first spring 10. The other end of the first spring 10 is connected to the mounting rod 8 of the pressure plate 81, thereby ensuring that the pressure plate 81 clamps and presses the tape, so that the tape is in a tightened state, which is convenient for stretching and cutting.

[0040] Reference Figure 1 The tape-pulling device 2 includes a drive assembly and a tape-clamping assembly; it is used to clamp one end of the tape and pull out a set length of tape under the drive of the drive assembly; the drive assembly includes a servo motor 21, a transmission belt 22, a synchronous pulley 23, a transmission slider 24, and a transmission guide rail 25; the servo motor 21 is provided on the base 4 and on the side near the fixed seat 5, the drive end of the servo motor 21 is provided with a synchronous pulley 23, there are at least two synchronous pulleys 23, the transmission belt 22 is provided on the two synchronous pulleys 23, and the transmission guide rail 25 is provided on the base 4. A transmission slider 24 is provided on the guide rail 25. The transmission slider 24 is fixedly connected to the transmission belt 22. A glue clamping assembly is provided on the transmission slider 24. When the servo motor 21 drives the synchronous pulley 23 to rotate, the synchronous pulley 23 rotates and drives the transmission belt 22 to drive. The transmission belt 22 drives the transmission slider 24 to slide on the transmission guide rail 25. The transmission slider 24 drives the glue clamping assembly to move. The drive motor precisely drives the transmission slider 24 to move a set distance, and drives the glue pulling device 2 to complete the precise glue pulling, thereby ensuring that the tape is stretched to the preset length.

[0041] Reference Figure 3The adhesive clamping assembly includes a tape-pulling base 26, a mounting plate 27, an upper clamping piece 28, a lower clamping piece 29, a clamping piece cylinder 211, and a second spring 212. The tape-pulling base 26 is fixedly connected to the transmission slider 24. The mounting plate 27 is provided on the tape-pulling base 26, and the upper clamping piece and the lower clamping piece 29 are provided on the mounting plate 27. The lower clamping piece 29 is hinged to the mounting plate 27 and is L-shaped. The clamping piece cylinder 211 is fixed on the tape-pulling base 26. The lifting rod of the clamping piece cylinder 211 contacts the lower part of the L-shaped lower clamping piece 29. The second spring 212 is located between the upper part of the L-shaped lower clamping piece 29 and the mounting plate 27. During the tape clamping process, the clamping piece cylinder 211 opens, the lifting rod extends, and the L-shaped lower clamping piece 29 and the upper clamping piece 28 work together to clamp the tape, ensuring that the tape can be stably stretched to the specified length.

[0042] Furthermore, a drag chain 41 and a limit block for the adhesive tray 26 are also provided on the base plate. One end of the drag chain 41 is connected to the adhesive tray 26, and a limit block for the adhesive tray 26 is provided on one side of the adhesive tray 26. The movement distance of the adhesive tray 26 is limited by the action of the drag chain 41 and the limit block for the adhesive tray 26.

[0043] Reference Figure 4 The tape-cutting device 3 includes a tape-cutting device base 4, a sliding cylinder 32, a sliding block 33, a tape-cutting cylinder 34, and a tape-cutting knife 35. The base 4 is mounted on a fixed seat 5. The sliding cylinder 32 is mounted on the base 4, and the sliding block 33 is mounted on the sliding cylinder 32. The sliding block 33 can slide relative to the sliding cylinder 32. The tape-cutting cylinder 34 is mounted on the sliding block 33. The tape-cutting knife 35 is mounted on the lifting rod of the tape-cutting cylinder 34. The tape-cutting knife includes a blade 351 and a blade holder 352. The blade holder 352 has the blade 351 mounted on it. When cutting the tape, the sliding cylinder 32 drives the sliding block 33 forward a certain distance. Then, the tape-cutting cylinder 34 opens, and the lifting rod moves upward, causing the tape-cutting knife 35 to cut the tape. After cutting the tape, the sliding cylinder 32 drives the sliding block 33 back to its original position. This ensures that an extra piece of tape is available for the next clamping device to pick up.

[0044] Specifically, an air supply cylinder is provided inside the base 4 of the rubber cutting device. A piston rod 36 is provided at one end of the air supply cylinder. An air inlet and an air outlet are provided at one end of the air supply cylinder. A one-way valve is provided in the air inlet. The air supply cylinder is existing technology. A first magnet 37 is provided at the extended end of the piston rod 36. A cylinder 213 is provided on one side of the rubber pulling seat 26. A second magnet 214 is provided at the end of the cylinder 213. When the rubber pulling seat 26 moves to a certain distance and the piston rod 36 is limited and cannot move to the right, the pulling force of the rubber pulling seat 26 on the second magnet 214 is greater than the attraction between the first magnet 37 and the second magnet 214. At this time, the first magnet 37 and the second magnet 214 will separate, thereby preventing the piston rod 36 from extending excessively and ensuring the service life of the piston rod 36.

[0045] Specifically, a limiting plate 38 is fixedly provided on one side of the rubber cutting cylinder 34. The limiting plate 38 is provided with a first air blowing hole 381 and a through hole. The through hole is connected to the first air blowing hole 381, and one end is connected to the air inlet through an air supply pipe. A second air blowing hole 382 is provided on the blade holder 352. The second air blowing hole 382 is connected to the through hole through an air supply pipe. There are at least two first air blowing holes 381 and second air blowing holes 382.

[0046] When the adhesive-pulling seat 26 resets, the second magnet 214 on the adhesive-pulling seat 26 will re-contact the first magnet 37, pushing the piston rod 36 to slowly reset. When the piston rod 36 resets, it will change the air pressure in the cylinder, squeezing the gas from the air outlet into the first through hole, and then blowing the gas through the first air blowing hole 381 and the second air blowing hole 382, ​​thereby blowing the tape up, so that the tape can float between the upper clamping plate 28 and the lower clamping plate 29, which is convenient for the upper clamping plate 28 and the lower clamping plate 29 to clamp it in the future, improving the efficiency of subsequent processing. At the same time, it eliminates the need for manual clamping and fixing of the tape, saving labor costs and improving the efficiency of automation. At the same time, blowing air can prevent the tape from sticking to the limit block during the tape pulling process, further ensuring that the tape can be pulled stably.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
