Description
Technical Field
[0001] This utility model relates to the field of glue dispensing machine technology, specifically to an anti-drip device for a dual-liquid automatic glue dispensing machine. Background Technology
[0002] In modern industrial production, dual-component automatic dispensing machines are a key piece of equipment widely used in numerous fields such as electronics, automotive, aerospace, and new energy. They precisely mix two different adhesives according to a preset ratio and automatically dispense them into specific parts of a product, achieving efficient and accurate bonding, sealing, and filling processes. For example, in electronic device manufacturing, they are used for chip packaging and circuit board coating; in automotive manufacturing, they are used for headlight sealing and bonding of body structural components. Precise dispensing operations play a crucial role in ensuring product quality and improving product performance.
[0003] However, in practice, two-component automatic dispensing machines often face the following problems:
[0004] Glue dripping problem: During the glue dispensing process, especially after dispensing is complete, residual glue often drips from the outlet of the dispensing tube. This dripping glue not only contaminates the work surface but may also drip onto the product, affecting its appearance and quality. Particularly in high-precision fields, such as electronic component packaging, glue dripping can lead to short circuits or functional failures.
[0005] Adhesive accumulation problem: Existing anti-drip devices usually use baffles to directly block the filling pipe outlet. Although this can prevent glue from dripping to a certain extent, the adhesive tends to accumulate on the baffles, requiring cleaning after each use, which increases the burden on operators and reduces production efficiency.
[0006] Difficulty in collecting adhesive: Existing anti-drip devices lack an effective adhesive collection mechanism, resulting in the inability to effectively collect and reuse dripping adhesive, causing waste of adhesive and increasing production costs.
[0007] Complex equipment maintenance: Existing anti-drip devices have complex structures, making maintenance and cleaning difficult. In particular, after prolonged use, the adhesive tends to solidify inside the device, leading to increased equipment failure rates and higher maintenance costs. Utility Model Content
[0008] The purpose of this utility model is to provide an anti-drip device for a two-component automatic dispensing machine, in order to solve the problem mentioned in the background art that the dispensing tube head is directly sealed by a baffle, and the glue falls onto the baffle and easily accumulates, which means that it needs to be cleaned every time it is used, and the glue cannot be effectively collected.
[0009] To achieve the above objectives, this utility model provides the following technical solution: an anti-drip device for a dual-liquid automatic dispensing machine, comprising a base and a connecting block. Support frames are installed on both the left and right sides of the base, and a top plate is installed between the support frames. A dispensing pipe is installed on the top plate. A movable box is provided above the base, and a connecting block is installed above the movable box. A ball screw is installed on the connecting block. An internal groove is provided inside the movable box, and a connecting plate is installed inside the internal groove. A forward and reverse motor is installed on the left side of the connecting plate. A rotating shaft is installed inside the internal groove through a bearing seat, and a scraper assembly is installed above the rotating shaft.

[0010] A guide block is installed on the right side of the movable box, and a movable strip runs through the guide block. A sealing plate is installed above the movable strip, and a collection through hole is opened on the sealing plate. A storage box is installed below the sealing plate.
[0011] Preferably, a dispensing head is installed on the top of the filling tube, and channels are provided on both the left and right sides of the dispensing head. The filling tube has two channels inside, and the two channels inside the dispensing head are respectively connected to the two channels inside the filling tube.
[0012] With the above structural design, the two-component adhesive in the dispensing head is delivered to the two channels in the filling tube through the internal dual channels, and then output through the filling tube to achieve dispensing.
[0013] Preferably, the movable box is equipped with a toolbox inside, a guide rod is installed on the left side of the movable box, the guide rod passes through the support frame on the left side, the guide rod is slidably connected to the support frame, a servo motor is installed on the left side of the left support frame, and the right side of the servo motor is connected to the ball screw through the output shaft.
[0014] With the above structural design, the servo motor is started, and the servo motor drives the ball screw to rotate. Since the movable box is installed on the ball screw through the connecting block, and the guide rod on the left side of the movable box passes through the left support frame and is slidably connected to it, the movable box will move left and right along the ball screw under the guidance of the guide rod. When dispensing glue, the movable box is moved to the left. When cleaning the lower end of the filling tube or sealing the lower end of the filling tube, the movable box is moved to the right.
[0015] Preferably, the rotating shaft passes through the upper right side of the movable box, and an inspection door is provided on the left side of the built-in slot. The inspection door is provided with heat dissipation holes. A transmission shaft is installed on the right side of the forward and reverse motor via an output shaft, and a first bevel gear is installed on the transmission shaft.
[0016] With the above structural design, when it is necessary to clean the lower end of the filling tube, the movable box is moved to the right until the scraper assembly is located at the lower end of the filling tube and abuts against the lower end of the filling tube. The forward and reverse motors are started, and the output shaft of the forward and reverse motors drives the transmission shaft to rotate. The first bevel gear on the transmission shaft rotates accordingly. The first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the rotating shaft to rotate, which in turn causes the scraper assembly above the rotating shaft to rotate. During the rotation, the scraper assembly scrapes off the residual adhesive on the filling tube.
[0017] Preferably, a second bevel gear is mounted on the rotating shaft, and the second bevel gear is perpendicular to and meshes with the first bevel gear. The rotating shaft reciprocates and rotates under the drive of the forward and reverse motors.
[0018] With the above structural design, when the first bevel gear rotates under force, it drives the second bevel gear to rotate, and the second bevel gear drives the rotating shaft to rotate.

[0020] With the above structural design, the scraped adhesive will slide down the inclined surface into the collection boxes on the front and rear sides, realizing the initial collection of residual adhesive. The collection box and the scraper assembly are detachably connected, which facilitates regular cleaning and replacement of the collection box.
[0021] Preferably, an installation plate is installed on the lower right side of the movable box, and a threaded rod is installed on the installation plate. The movable bar is connected to the threaded rod. The storage box is located directly below the collection through hole. Abutment blocks are installed on both the left and right sides of the upper surface of the storage box, and strong magnetic blocks are installed on the upper surface of the abutment blocks. The strong magnetic blocks are attracted to the lower surface of the sealing plate. When the movable box moves to the left, it drives the sealing plate to move to the left. When it moves away from the filling tube, the sealing plate does not contact the ball screw.
[0022] With the above structural design, when sealing the filling tube, the scraper assembly is rotated away from the filling tube, and then the threaded rod on the mounting plate is rotated. The movable strip moves upward under the guidance of the guide block, which in turn drives the sealing plate and the storage box to move upward. The sealing plate seals the bottom of the filling tube to prevent glue leakage. A small amount of glue in the filling tube will fall into the storage box below through the collection hole, which is convenient for collecting the glue.

[0035] Please see Figures 1-6This utility model provides a technical solution: an anti-drip device for a dual-liquid automatic dispensing machine, comprising a base 1, a support frame 2, a top plate 3, a dispensing tube 4, a dispensing head 5, a movable box 6, a connecting block 7, a servo motor 8, a ball screw 9, a guide rod 10, an internal groove 11, a connecting plate 12, a forward and reverse motor 13, a transmission shaft 14, a first bevel gear 15, a rotating shaft 16, a second bevel gear 17, a scraper assembly 18, a collection box 19, a mounting plate 20, a threaded rod 21, a movable strip 22, a guide block 23, a sealing plate 24, a collection through hole 25, a storage box 26, an abutment block 27, and a strong magnetic block 28. Support frames 2 are installed on both the left and right sides of the base 1, and a top plate 3 is installed between the support frames 2. A dispensing tube 4 is installed on the top plate 3. A dispensing head 5 is installed above the base 1, and channels are provided on both the left and right sides of the dispensing head 5. The filling tube 4 has two internal channels, which are connected to the two internal channels of the filling tube 4. The two-component adhesive in the dispensing head 5 is delivered to the two internal channels of the filling tube 4, and then output through the filling tube 4, thus completing the dispensing process. A movable box 6 is installed above the base 1, containing a toolbox. A guide rod 10 is installed on the left side of the movable box 6, passing through the left support frame 2 and slidably connected to it. A servo motor 8 is installed on the left side of the left support frame 2, and its right side is connected to a ball screw 9 via an output shaft. When the servo motor 8 is started... The ball screw 9 is driven to rotate. Since the movable box 6 is mounted on the ball screw 9 via the connecting block 7, and the guide rod 10 on the left side of the movable box 6 passes through the left support frame 2 and is slidably connected to it, the movable box 6 moves left and right along the ball screw 9 under the guidance of the guide rod 10. When dispensing glue, the movable box 6 is moved to the left; when cleaning the lower end of the filling tube 4 or sealing the lower end of the filling tube 4, the movable box 6 is moved to the right. A connecting block 7 is installed on the top of the movable box 6, and the ball screw 9 is installed on the connecting block 7. An internal groove 11 is opened inside the movable box 6, and a connecting plate 12 is installed inside the internal groove 11. A forward / reverse motor 13 is installed on the left side of the connecting plate 12. A rotating shaft 16 is installed inside the internal groove 11 via a bearing seat, and the rotating shaft 16... A scraper assembly 18 is installed at the top, and collection boxes 19 are installed on both the front and rear sides of the scraper assembly 18. A rotating shaft 16 passes through the upper right side of the movable box 6. An inspection door with heat dissipation holes is provided on the left side of the internal slot 11. A drive shaft 14 is installed on the right side of the forward and reverse motor 13 via an output shaft, and a first bevel gear 15 is installed on the drive shaft 14. When it is necessary to clean the lower end of the filling tube 4, the movable box 6 is moved to the right until the scraper assembly 18 is located directly below the filling tube 4 and abuts against the lower end of the filling tube 4. The forward and reverse motor 13 is started, and the output shaft of the forward and reverse motor 13 drives the drive shaft 14 to rotate. The first bevel gear 15 on the drive shaft 14 rotates accordingly, and the first bevel gear 15 drives the second bevel gear 17 to rotate.The second bevel gear 17 drives the rotating shaft 16 to rotate, which in turn causes the scraper assembly 18 above the rotating shaft 16 to rotate. During rotation, the scraper assembly 18 scrapes off the residual adhesive on the filling tube 4. The rotating shaft 16 is equipped with the second bevel gear 17, which is perpendicular to and meshes with the first bevel gear 15. Driven by the forward and reverse motor 13, the rotating shaft 16 reciprocates. When the first bevel gear 15 rotates under force, it drives the second bevel gear 17 to rotate, which in turn drives the rotating shaft 16 to rotate. The collection box 19 is detachably connected to the scraper assembly 18. The upper surface of the scraper assembly 18 has a sloped design, allowing the scraped adhesive to slide down the slope into the collection boxes 19 on both sides, achieving initial collection of residual adhesive. The detachable connection between the collection box 19 and the scraper assembly 18 facilitates regular cleaning and replacement of the collection box 19.
[0036] A guide block 23 is installed on the right side of the movable box 6, and a movable strip 22 runs through the guide block 23. A sealing plate 24 is installed above the movable strip 22, and a collection through hole 25 is opened on the sealing plate 24. A storage box 26 is installed below the sealing plate 24. An installation plate 20 is installed on the lower right side of the movable box 6, and a threaded rod 21 is installed on the installation plate 20. The movable strip 22 is connected to the threaded rod 21. The storage box 26 is located directly below the collection through hole 25. Abutment blocks 27 are installed on both the left and right sides of the upper surface of the storage box 26, and strong magnetic blocks 28 are installed on the upper surface of the abutment blocks 27. The strong magnetic blocks 28 are attracted to the lower surface of the sealing plate 24. The movable box 6 moves to the left, causing the sealing plate to move. When the sealing plate 24 moves to the left, away from the filling tube 4, it does not contact the ball screw 9. When sealing the filling tube 4, the scraper assembly 18 is rotated away from the filling tube 4, and then the threaded rod 21 on the mounting plate 20 is rotated. The movable bar 22 will move upward under the guidance of the guide block 23, thereby driving the sealing plate 24 and the storage box 26 to move upward. The bottom of the filling tube 4 is sealed by the sealing plate 24 to prevent glue leakage. A small amount of glue in the filling tube 4 will fall into the storage box 26 below through the collection hole 25, which is convenient for collecting the glue. When disassembling the storage box 26, simply pull the storage box 26 downward to make the strong magnet 28 away from the sealing plate 24.
[0037] Working principle: When using the anti-drip device for the dual-liquid automatic dispensing machine, firstly, start the servo motor 8, which drives the ball screw 9 to rotate. Since the movable box 6 is installed on the ball screw 9 through the connecting block 7, and the guide rod 10 on the left side of the movable box 6 passes through the left support frame 2 and is slidably connected to it, the movable box 6 will move left and right along the ball screw 9 under the guidance of the guide rod 10. When dispensing glue, move the movable box 6 to the left. When cleaning the lower end of the filling tube 4 or sealing the lower end of the filling tube 4, move the movable box 6 to the right.
[0038] When it is necessary to clean the lower end of the filling tube 4, move the movable box 6 to the right until the scraper assembly 18 is located directly below the filling tube 4 and abuts against the lower end of the filling tube 4. Start the forward and reverse motor 13. The output shaft of the forward and reverse motor 13 drives the transmission shaft 14 to rotate. The first bevel gear 15 on the transmission shaft 14 rotates accordingly. The first bevel gear 15 drives the second bevel gear 17 to rotate. The second bevel gear 17 drives the rotating shaft 16 to rotate, which in turn causes the scraper assembly 18 above the rotating shaft 16 to rotate. During the rotation, the scraper assembly 18 scrapes off the residual adhesive on the filling tube 4. The scraped adhesive slides down the inclined surface into the collection boxes 19 on the front and rear sides, achieving the initial collection of residual adhesive. The collection box 19 is detachably connected to the scraper assembly 18, which is convenient for regular cleaning and replacement of the collection box 19.
[0039] When sealing the filling tube 4, rotate the scraper assembly 18 away from the filling tube 4, and then rotate the threaded rod 21 on the mounting plate 20. The movable bar 22 will move upward under the guidance of the guide block 23, thereby driving the sealing plate 24 and the storage box 26 upward. The sealing plate 24 seals the bottom of the filling tube 4 to prevent glue leakage. A small amount of glue in the filling tube 4 will fall into the storage box 26 below through the collection hole 25 for easy collection. When disassembling the storage box 26, simply pull the storage box 26 downward to move the strong magnet 28 away from the sealing plate 24, thus completing a series of operations. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
