Technical Field
[0001] This utility model relates to the field of industrial automation, specifically to an automatic glue application and dispensing machine. Background Technology
[0002] In the field of industrial automation production, dispensing is a key process in scenarios such as electronic component packaging, medical device assembly, and automotive parts manufacturing. Its core is to accurately apply glue to designated locations to achieve functions such as component bonding, sealing, or insulation. With the continuous improvement of production efficiency and product precision requirements, dispensing equipment that can only perform a single glue application action can no longer meet the needs. Automatic glue-wiping dispensing machines have emerged to address this issue. Based on the traditional dispensing function, they integrate an automatic glue-wiping module, which can remove residual glue residue from the dispensing needle and excess glue from the workpiece surface after each dispensing. This prevents glue from drying and clogging the needle, affecting the accuracy of subsequent dispensing, and reduces the defect rate of workpieces due to glue residue. It is an important piece of equipment to ensure continuous and high-precision production.
[0003] However, traditional dispensing technologies generally rely on manual labor or simple mechanical structures to complete the glue application: manual glue application requires operators to frequently clean the needle and workpiece manually, which not only consumes a lot of labor costs, but also makes it difficult to unify the glue application force and frequency, easily resulting in incomplete glue removal or excessive wiping that damages the needle and workpiece; simple mechanical glue application structures mostly use fixed brushes or scrapers, which can only clean a single part of the needle or a part of the workpiece, and cannot be adapted to different specifications of needles and complex workpiece shapes. In addition, the glue application and dispensing actions in traditional technologies lack coordination, and the glue application process often needs to be interrupted, which greatly extends the production time of a single process and is difficult to adapt to the high-speed operation requirements of modern production lines, thus restricting the improvement of overall production efficiency. To address this, we propose an automatic glue application and dispensing machine. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic glue application and dispensing machine, which solves the aforementioned problems.

A cylindrical rotating shaft is fixedly mounted at the center of the top surface of the spur gear, and the rotating shaft is fixedly mounted to the motor shaft of the motor housing through a through hole in the support beam.

[0009] Preferably, the rotating structure includes a rotating rod, a secondary gear, and a rotating column. The rotating rod is an L-shaped rocker that rotates 90 degrees, and four sets of rotating rods are distributed in a ring at equal intervals. The horizontal end of the rotating rod is fixedly installed at the center of the side of the secondary gear, and the horizontal end of the rotating rod is rotatably connected to the rotating hole. The secondary gear meshes with the gear ring. A cylindrical rotating column is fixedly installed on the side of the vertical end of the rotating rod, and four sets of rotating columns are distributed in a ring at equal intervals. The length of the vertical end of the rotating rod is equal to half the length of the square inside the support column.
[0010] Preferably, the lifting structure includes a connecting rod, a rotating hole, a lifting block, and a wiping block.

This fully meets the high-speed, continuous production needs of modern production lines, resulting in a significantly higher single-shift output compared to traditional equipment.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-4 An automatic glue dispensing machine includes a three-axis base 1, a housing 2, a support beam 3, a dispensing structure 4, and a motor housing 5. The three-axis base 1 is a gantry-type three-axis worktable. The housing 2 is fixedly installed on the side of the Z-axis slider of the three-axis base 1. The support beam 3 is fixedly installed on the inner side wall of the housing 2, and the top surface of the support beam 3 has a through groove. The dispensing structure 4 is fixedly installed in the through groove of the support beam 3. The motor housing 5 is fixedly installed on the inner upper right side wall of the housing 2. An automatic adhesive application assembly is installed on the bottom surface of the support beam 3. The automatic adhesive application assembly includes a fixed structure, a transmission structure, a rotating structure, and a lifting structure. The fixed structure is installed on the bottom surface of the support beam 3 at the position corresponding to the through groove. The transmission structure is installed on the side of the fixed structure. The rotating structure is installed inside the fixed structure and connected to the transmission structure. The lifting structure is installed inside the fixed structure and connected to the rotating structure.
[0016] Furthermore, the outer shell 2 is a hollow cube with an opening at the bottom. Two sets of support beams 3 are vertically equidistant, and each support beam 3 has a through-hole on the top surface of the motor housing 5. The hollow cube design of the outer shell 2 with an opening at the bottom provides a closed installation and working space for the core components such as the internal support beams 3 and the automatic adhesive application assembly, preventing external dust and impurities from entering, reducing component wear, and ensuring long-term stable operation of the equipment. On the other hand, the bottom opening allows the automatic adhesive application assembly to smoothly complete the adhesive application operation by lifting and lowering, avoiding interference from the outer shell 2 on the component's movement. The vertically equidistant distribution of the two sets of support beams 3, with through-holes on the top surface of the motor housing 5, allows the support beams 3 to evenly distribute the weight of the dispensing structure 4 and the automatic adhesive application assembly, improving the overall structural stability and preventing component deformation due to excessive local stress.
[0017] Furthermore, the fixing structure includes a support column 6 and rotating holes 7. The support column 6 is a hollow cylinder with an internal square shape, and both its top and bottom surfaces have openings. The support column 6 is fixedly installed on the bottom surface of the support beam 3 at the corresponding through slot position. The internal sidewalls of the support column 6 are all provided with through-holes 7, and four sets of rotating holes 7 are distributed in a ring at equal intervals. The hollow internal square design of the support column 6 in the fixing structure, combined with the four sets of rotating holes 7, provides installation and rotation positioning for the rotating rods 13 of the rotating structure, allowing the four sets of rotating rods 13 to be positioned in the same plane. The ring rotates stably at equal intervals; the top and bottom openings facilitate the passage of the dispensing structure 4, while the internal square space provides lifting space for the lifting block 18 of the lifting structure, preventing the support column 6 from obstructing the up-and-down movement of the lifting block 18. The four sets of ring-shaped equally spaced rotating holes 7, in addition to forming a rotational fit with the horizontal end of the rotating rod 13, can also keep the force and movement of the four sets of rotating rods 13 synchronized through the evenly distributed holes, preventing the rotation angle deviation of the rotating rod 13 due to uneven distribution of the rotating holes 7, thereby ensuring that the subsequent lifting structure can smoothly drive the dispensing block 19 to rise and fall, improving the uniformity and accuracy of the dispensing operation.
[0018] Furthermore, the transmission structure includes a rotating groove 8, a gear ring 9, a rotating rail 10, a secondary gear ring 11, and a spur gear 12. The support column 6 has dovetail-shaped rotating grooves 8 on its side, with two sets of rotating grooves 8 vertically equidistantly distributed. The gear ring 9 is a hollow cylinder with an internal hollow core, and two sets of gear rings 9 are axially symmetrically distributed. Dovetail-shaped rotating rails 10 are fixedly installed on the inner sidewalls of each gear ring 9, and the rotating rails 10 are rotatably connected to the rotating grooves 8. A secondary gear ring 11 is fixedly installed on the side of one set of gear rings 9. A cylindrical rotating shaft is fixedly installed at the center of the top surface of the spur gear 12, and the rotating shaft is fixedly installed to the motor shaft of the motor housing 5 through the through hole of the support beam 3. The spur gear 12 meshes with the secondary gear ring 11. The two sets of vertically equidistant dovetail-shaped rotating grooves 8 on the side of the support column 6 form a rotatable engagement with the dovetail-shaped rotating rails 10 inside the gear ring 9. The engagement method not only restricts the movement trajectory of the gear ring 9, allowing it to rotate only around the axis of the support column 6, thus preventing the gear ring 9 from shifting up and down or wobbling during rotation; at the same time, the dovetail structure design increases the contact area between the rotating rail 10 and the rotating groove 8, improving the stability and load-bearing capacity of their connection. This allows the gear ring 9 to withstand greater torque when driving the rotating structure, reducing energy loss during transmission. The two sets of gear rings 9 are symmetrically distributed, with one set of side-fixed auxiliary gear ring 11 meshing with the spur gear 12. When the motor housing 5 drives the spur gear 12 to rotate, the auxiliary gear ring 11 will synchronously drive the corresponding gear ring 9 to rotate, thereby driving the auxiliary gears between the two sets of gear rings 9 to rotate in both directions. This ensures that the rotating rods 13 of the four rotating structures are evenly stressed and operate synchronously, providing a guarantee for the stable lifting of the lifting structure.
[0019] Furthermore, the rotating structure includes a rotating rod 13, a secondary gear 14, and a rotating column 15. The rotating rod 13 is an L-shaped rocker arm that rotates 90 degrees, and four sets of rotating rods 13 are distributed in a ring at equal intervals. The horizontal end of the rotating rod 13 is fixedly installed at the center of the side of the secondary gear 14, and the horizontal end of the rotating rod 13 is rotatably connected to the rotating hole 7. The secondary gear 14 meshes with the gear ring 9. A cylindrical rotating column 15 is fixedly installed on the side of the vertical end of the rotating rod 13, and four sets of rotating columns 15 are distributed in a ring at equal intervals. The length of the vertical end of the rotating rod 13 is equal to half the length of the square inside the support column 6. The four sets of ring-shaped rotating rods 13, distributed at equal intervals and in a 90-degree L-shape, have their horizontal ends rotatably connected to the rotating hole 7 and their vertical ends fixed to the rotating column 15. The L-shaped structure design allows the rotating rod 13 to... Within the limited internal space of the support column 6, the circular rotation around the rotating hole 7 is transformed into an arc motion of the rotating column 15. The equidistant distribution in a ring ensures that the movement of the four sets of rotating rods 13 remains highly synchronized, preventing the lifting structure from becoming unbalanced due to uneven distribution of the rotating rods 13. This also prevents the wiping block 19 from tilting during lifting. The length of the vertical end of the rotating rod 13 is equal to half the length of the square inside the support column 6. This size design allows the rotating column 15 at the vertical end of the rotating rod 13 to form the maximum effective radius of motion inside the support column 6 when the rotating rod 13 rotates. This allows the rotating column 15 to drive the lifting block 18 through the connecting rod 16 to achieve sufficient lifting stroke, while avoiding collision between the rotating column 15 and the inner wall of the support column 6 during movement, ensuring the smooth operation of the rotating structure.
[0020] Furthermore, the lifting structure includes a connecting rod 16, a rotating hole 17, a lifting block 18, and a wiping block 19. The connecting rod 16 is an oblong block, and four sets of connecting rods 16 are distributed in a ring at equal intervals. The sides of each connecting rod 16 have through rotating holes 17, and two sets of rotating holes 17 are distributed vertically at equal intervals. The length of the connecting rod 16 is equal to the length of the vertical end of the rotating rod 13, and the rotating hole 17 at the top of the connecting rod 16 is rotatably connected to the rotating column 15. The lifting block 18 is a hollow, circular block. The lifting block 18 has cylindrical columns fixedly installed on its sides. The columns on the sides of the lifting block 18 are rotatably connected to the rotating holes 17 at the bottom of the connecting rod 16. The inner sidewalls and bottom surfaces of the lifting block 18 are fixedly fitted with adhesive blocks 19. Four sets of annularly distributed elongated oval connecting rods 16 have rotating holes 17 at their tops that are rotatably connected to rotating columns 15, and rotating holes 17 at their bottoms that are rotatably connected to the columns on the sides of the lifting block 18. The elongated oval structure design allows the connecting rods 16 to rotate the arc of the rotating columns 15. The smooth motion is transformed into the linear lifting motion of the lifting block 18; the equidistant ring distribution ensures that the lifting block 18 maintains a horizontal lifting state under the synchronous drive of the four sets of connecting rods 16, preventing the lifting block 18 from tilting or deviating, and allowing the adhesive wiping block 19 to evenly contact the workpiece surface. The lifting block 18 has a hollow circular interior and fixed columns on the sides. The hollow circular design can be adapted to the shape of the dispensing needle, allowing the adhesive wiping block 19 to perform adhesive wiping operations on the dispensing needle and the top surface of the workpiece. The cooperation between the side columns and the bottom rotating holes 17 of the connecting rods 16 provides a stable mounting point for the connecting rods 16, enabling the connecting rods 16 to transmit power efficiently. At the same time, the cylindrical structure of the columns reduces friction with the rotating holes 17, improving the smoothness of the lifting block 18's lifting motion. The adhesive wiping blocks 19, which are fixed on both the inner side walls and the bottom surface of the lifting block 18, can simultaneously wipe the dispensing needle and the top surface of the workpiece. Compared with single-sided adhesive wiping, this can significantly improve the adhesive wiping efficiency and quality, and avoid local adhesive residue on the workpiece.
[0021] Structural Description: Three-axis base 1: It is a gantry-type three-axis worktable. The X, Y and Z axes are driven by motors to move and position the whole machine, so that the dispensing and wiping positions are accurate. Outer shell 2: Outer shell 2 is a hollow cube with an open bottom, used to accommodate components such as support beams and dispensing structures, providing a closed space to prevent dust and impurities, and not hindering the movement of internal components; Support beam 3: The support beam 3 is vertically and equidistantly distributed inside the shell.

Dispensing structure 4: The dispensing structure 4 is fixed in the through groove of the support beam 3. It is the core component of the dispensing function, which controls the amount and position of dispensing and completes the dispensing operation on the workpiece.

Support column 6: Support column 6 is fixed to the corresponding position of the through groove on the bottom surface of support beam 3. It is a square hollow cylinder inside, providing installation space and support for the rotating structure and lifting structure. Rotary hole 7: Rotary hole 7 is opened on the inner side wall of support column 6, and four sets of annular equidistant distribution are used to cooperate with the horizontal end of rotating rod 13, so that rotating rod 13 can rotate around it in a circle. Rotary groove 8: Rotary groove 8 is opened on the side of the support column 6, in the shape of a dovetail, with two sets of vertically equidistantly distributed, which cooperate with the inner rotating rail 10 of the gear ring 9 to limit the movement trajectory of the gear ring 9; Gear ring 9: Gear ring 9 is a hollow cylinder with two sets of axially symmetrically distributed. The inner rotating rail 10 rotates in conjunction with the rotating groove 8 and drives the rotating rod 13 to move by meshing with the auxiliary gear 14. Rotary rail 10: Rotary rail 10 is fixed to the inner wall of gear ring 9, and is dovetail shaped. It rotates and engages with the rotating groove 8 on the side of the support column 6, so that gear ring 9 can rotate stably around the axis. Secondary gear ring 11: The secondary gear ring 11 is fixed on the side of a set of gear rings 9 and meshes with the spur gear 12 to transmit the power of the spur gear 12 to the gear ring 9, thereby realizing transmission. Spur Gear 12: The top surface of spur gear 12 is connected to the motor shaft of motor housing 5 and meshes with the auxiliary gear ring 11 to transmit motor power and drive the gear ring 9 to rotate; Rotating rod 13: Rotating rod 13 is L-shaped with four sets of rings evenly distributed. The horizontal end is matched with the rotating hole 7, and the vertical end is fixed with the rotating column 15, which converts the circular motion into the lifting power of the lifting block 18. Secondary gear 14: The secondary gear 14 is fixed at the center of the horizontal end of the rotating rod 13, meshes with the gear ring 9, receives the power of the gear ring 9, and drives the rotating rod 13 to rotate; Rotating column 15: The rotating column 15 is fixed to the side of the vertical end of the rotating rod 13 and cooperates with the rotating hole 17 at the top of the connecting rod 16 to convert the rotation of the rotating rod 13 into the movement of the connecting rod 16. Link 16: Link 16 is an elongated oval block with four sets of equidistant rings. The top of the link cooperates with the rotating column 15 and the bottom of the lifting block 18 column to make the lifting block 18 rise and fall smoothly.

The side column and the connecting rod 16 cooperate with each other. The adhesive wiping block 19 is fixed inside and on the bottom to realize the adhesive wiping action. Glue removal block 19: The glue removal block 19 is fixed to the inner side wall and bottom surface of the lifting block 18. It is made of elastic and wear-resistant material and is used to remove glue residue from the dispensing needle and the workpiece surface.
[0022] Working Principle: During operation of the automatic glue dispensing machine, after dispensing is completed, the motor housing 5 opens, the motor runs, and drives the spur gear 12 to rotate. The spur gear 12 is securely connected to the motor shaft via a cylindrical rotating shaft at the center of its top surface and a through hole in the support beam 3. The spur gear 12 meshes with a secondary gear ring 11 on the side of a set of gear rings 9. When the spur gear 12 rotates, the secondary gear ring 11 synchronously drives the corresponding gear ring 9 to rotate around the axis of the support column 6. Simultaneously, the rotation of the gear ring 9, through meshing with the secondary gear 14, drives another set of gear rings 9 to rotate synchronously in the opposite direction. Four sets of equally spaced, annular secondary gears 14 are fixed at the center of the horizontal end of the rotating rod 13. As the gear rings 9 rotate, the secondary gears 14 also rotate accordingly, thereby driving the connected rotating rod 13 to rotate around the rotating hole 7 of the support column 6. The horizontal end of the rotating rod 13 rotatably engages with the rotating hole 7, and the vertical end is fixed to the rotating column 15. The circular rotation is converted into the arc motion of the rotating column 15, and the rotating rod 13 drives the lifting block 18 to move vertically up and down through the connecting rod 16. The lifting block 18 is circular and hollow inside, which is adapted to the shape of the dispensing needle. The inner side wall and bottom surface are fixed with the glue wiping block 19. When the rotating rod 13 drives the connecting rod 16 to move, the lifting block 18 is driven by the four sets of connecting rods 16 in a synchronous manner to maintain a horizontal state for lifting and lowering. When it descends, the glue wiping block 19 on the inner side wall can perform glue wiping operation on the dispensing needle. When it descends beyond the dispensing needle, the motor box 5 pauses and the glue wiping block 19 stops. The dispensing program of the dispensing needle is run again. The glue wiping block 19 on the bottom surface performs glue wiping operation on the top surface of the workpiece. Because the glue wiping block 19 is made of elastic and wear-resistant material, it can effectively remove glue stains. And through elasticity, it can adapt to a certain deviation, so that the glue wiping is comprehensive and uniform. Then the motor box 5 is opened, and the lifting block 18 is raised back into the support column 6, exposing the dispensing needle to continue the glue dispensing operation.
