Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1, refer to Figure 1-2 , a desktop automatic glue dispenser, including a glue dispenser main body 1 and a frame 2. A feeding bucket 3 is arranged on the frame 2. A screen plate 13 is movably arranged inside the feeding bucket 3. In the initial state, the screen plate 13 is located at the bottom of the feeding bucket 3.

[0034] Refer to Figure 9 , a pipe fitting 6 is installed at the top of the threaded rod 10. A disc 9 is slidably arranged outside the pipe fitting 6. A plate body 23 is arranged outside the pipe fitting 6. A vertical slot 22 is arranged inside the disc 9, and the plate body 23 slides in the vertical slot 22. A chassis 20 is installed at the outer top of the feeding bucket 3.

[0035] Refer to Figure 7 , the top of the pipe fitting 6 extends into the chassis 20, and a transmission assembly 4 is arranged at the top position of the pipe fitting 6. The transmission assembly 4 includes a first transmission gear 41, a stepping motor 42 and a second transmission gear 43. The second transmission gear 43 is arranged at the end of the output shaft of the stepping motor 42. The stepping motor 42 is installed on the top of the chassis 20. The first transmission gear 41 is installed on the pipe fitting 6, and the first transmission gear 41 meshes with the second transmission gear 43.

[0036] A threaded rod 10 is arranged at the center position of the bottom of the feeding bucket 3. A threaded sleeve 12 is installed at the center position of the screen plate 13. The threaded rod 10 passes through the threaded sleeve 12, and the threaded sleeve 12 cooperates with the threaded rod 10.

[0037] Refer to Figure 8 , a guiding assembly 14 is arranged between the screen plate 13 and the inner wall of the feeding bucket 3. The guiding assembly 14 includes a guide rail 141 and a connecting block 142. The guide rail 141 is vertically arranged inside the feeding bucket 3. The connecting block 142 is connected to the side wall of the screen plate 13. The connecting block 142 is slidably arranged in the guide rail 141. When the screen plate 13 is about to reach the highest point, the activated carbon rod 5 will rotate at the upper end position of the screen plate 13.

[0038] A conveyor track is provided on the base of the main body 1 of the dispensing machine. The object to be processed is placed on the upper end for position control. At the same time, the frame 2 can move horizontally, and the dispensing head can be adjusted in height. The dispensing machine is a commonly used dispensing device in the existing market, and will not be elaborated here.

[0039] After injecting the glue into the supply barrel 3 through the pump body, during the actual operation of the equipment, the glue head is often blocked due to impurities in the glue, resulting in glue breakage and trailing. By stirring, the impurities in the glue are suspended and then filtered, which will increase the bubbles in the glue.

[0040] Therefore, through the power output of the stepping motor 42, the first transmission gear 41 and the second transmission gear 43 are driven to rotate, and the kinetic energy is transmitted to the pipe fitting 6. Since the pipe fitting 6 is connected to the threaded rod 10, during the rotation of the threaded rod 10, a lead screw structure will be formed with the threaded sleeve 12 on the screen plate 13, driving the screen plate 13 to lift. Secondly, during the upward movement of the screen plate 13, in order to prevent the screen plate 13 from deflecting, a connecting block 142 is provided on one side. The connecting block 142 cooperates with the guide rail 141 on the supply barrel 3 to provide a guiding effect on the screen plate 13. During the upward movement of the screen plate 13, after the impurities come into contact with the screen plate 13, the impurities are adsorbed on the surface of the screen plate 13 and rise together with the lifting of the screen plate 13, separating the insoluble suspended impurities and colloids contained in the glue from the glue, and avoiding the problem of blockage when these substances enter the dispensing head.

[0041] Example 2, refer to Figures 3-5 , the difference between this embodiment and Embodiment 1 is that an adsorption assembly is provided above the screen plate 13. The adsorption assembly includes an activated carbon rod 5, a round tube 7, a slot hole 8 and a disc 9. The round tube 7 is rotatably arranged between the disc 9 and the activated carbon rod 5, and the inside of the activated carbon rod 5 is hollow. The slot hole 8 is opened on its outer surface along the axis direction of the activated carbon rod 5. The inside of the activated carbon rod 5 is interconnected with the inside of the disc 9 through the round tube 7.

[0042] When these suspended substances and colloids are located above the screen plate 13, they need to be collected and transferred in a timely manner.

[0043] To this end, activated carbon rods 5 are rotatably arranged outside the disc 9 through multiple round tubes 7 and come into contact with the activated carbon rods 5 during the upward movement of the mesh plate 13. At this time, the mesh plate 13 has an upward lifting force on the activated carbon rods 5, causing the disc 9 to lift upward outside the pipe fitting 6. When the position of the disc 9 is lifted, the plate body 23 outside the pipe fitting 6 moves upward in the vertical groove 22 inside the disc 9. At the same time, since the plate body 23 comes into contact with the vertical groove 22 during rotation, when the position of the disc 9 is lifted, rotation can still be achieved. During the rotation process, the activated carbon rods 5 roll on the surface of the mesh plate 13, enabling the outer surface of the activated carbon rods 5 to uniformly adsorb the suspended substances and colloids on the surface of the mesh plate 13.

[0044] Example 3, refer to Figure 6 , the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the inner side of the pipe fitting 6 is filled with an anti-seepage agent. A plurality of second diversion holes 21 are uniformly formed in the disc 9, and the positions of the second diversion holes 21 correspond one by one to the reserved holes on the pipe fitting 6. A plurality of longitudinal chambers 17 are uniformly formed inside the disc 9. An adjusting assembly is arranged inside the chamber 17. The adjusting assembly includes an elastic column 16, a moving seat 18, and a first diversion hole 19; the moving seat 18 slides inside the chamber 17, the first diversion hole 19 is formed through the moving seat 18, and an elastic column 16 is further arranged between the top of the chamber 17 and the moving seat 18, and the first diversion hole 19 corresponds to the second diversion hole 21.

[0045] Refer to Figures 4-5 , an annular groove 15 is formed at the bottom of the disc 9, and the annular groove 15 is communicated with the plurality of chambers 17. An annular plate 11 is installed at the top of the threaded sleeve 12. In the initial state, the first diversion hole 19 and the second diversion hole 21 do not coincide with each other. When the annular plate 11 rises to the highest point, the annular plate 11 jacks up the moving seat 18 upward. At this time, the first diversion hole 19 and the second diversion hole 21 coincide with each other.

[0046] During the dispensing process, the problem of infiltration will occur, and an anti-seepage agent needs to be added to the glue to inhibit this situation. However, on the premise that stirring is not allowed, the fluidity of the glue is poor, and the added anti-seepage agent cannot be evenly spread in the glue.

[0047] Therefore, during the upward movement of the disc 9, the second diversion holes 21 on the disc 9 will coincide with the positions of the reserved holes outside the pipe fitting 6. At this time, the anti-seepage agent pre-stored inside the pipe fitting 6 enters the second diversion holes 21. Meanwhile, the annular plate 11 pushes the moving seat 18 upward, causing the second diversion holes 21 to coincide with the first diversion holes 19. The anti-seepage agent flows through the second diversion holes 21 and the first diversion holes 19 and enters the activated carbon rods 5 through the round pipe 7. When the activated carbon rods 5 are in the initial state, the slot holes 8 on their outer sides are at the highest position. When the activated carbon rods 5 roll, the positions of the slot holes 8 change, and the anti-seepage agent leaks out from the slot holes 8 and falls on the mesh plate 13. As the activated carbon rods 5 roll, the anti-seepage agent is evenly smeared on the mesh plate 13. It should be noted that during the process when the activated carbon rods 5 continue to contact the mesh plate 13 after adsorbing the colloid and suspended substances, the adsorbed colloid and suspended substances will not be thrown out. This is because activated carbon has a huge specific surface area and a rich pore structure, and can adsorb impurities through the van der Waals force between molecules. Once the impurities are adsorbed on the activated carbon, they will not be easily desorbed.

[0048] When the mesh plate 13 is about to reach the highest point, start the stepping motor 42 to reverse, driving the mesh plate 13 to descend. Since the mesh plate 13 is in a porous state, the anti-seepage agent forms a film on the surface of the mesh plate 13. At the same time, the anti-seepage agent can adhere to the inner sides of the mesh holes on the mesh plate 13, which also increases the area where the anti-seepage agent is distributed and also increases the contact area with the glue. When the mesh plate 13 descends and contacts the glue, these glues contact the anti-seepage agent in the sieve holes. Due to the increased contact area, the collision probability between the molecules of the two liquids increases, and the mixing rate will also increase accordingly, enabling the anti-seepage agent to be evenly diffused into the glue.

[0049] The working principle of this device is as follows:

[0050] On the base of the dispensing machine main body 1, there are conveyor tracks. Place the object to be processed on the upper end for position control. Meanwhile, the frame 2 can move horizontally, and the dispensing head can adjust the height. The dispensing machine is a commonly used dispensing device in the existing market, and its working principle and model will not be elaborated here.

[0051] After injecting the glue into the supply bucket 3 through the pump body, during the actual operation of the equipment, since the glue often contains impurities, it may cause the glue head to be blocked, resulting in glue breakage and trailing. By stirring, the impurities in the glue are suspended, and then filtered, which will increase the bubbles in the glue.

[0052] To this end, through the power output of the stepper motor 42, the first transmission gear 41 and the second transmission gear 43 are driven to rotate, and the kinetic energy is transmitted to the pipe fitting 6. Since the pipe fitting 6 is connected to the threaded rod 10, during the rotation of the threaded rod 10, a lead screw structure will be formed with the threaded sleeve 12 on the mesh plate 13, driving the mesh plate 13 to lift. Secondly, during the upward movement of the mesh plate 13, in order to prevent the mesh plate 13 from deflecting, a connecting block 142 is provided on one side thereof, and the connecting block 142 cooperates with the guide rail 141 on the feeding bucket 3 to provide a guiding effect on the mesh plate 13. During the upward movement of the mesh plate 13, after the impurities come into contact with the mesh plate 13, the impurities are adsorbed on the surface of the mesh plate 13 and rise together with the lifting of the mesh plate 13, separating the insoluble suspended impurities and colloids contained in the glue from the glue, and avoiding the problem of blockage when these substances enter the dispensing head.

[0053] When these suspended substances and colloids are located at the upper end of the mesh plate 13, it is necessary to collect and transfer them in a timely manner.

[0054] To this end, activated carbon rods 5 are rotatably arranged outside the disc 9 through a plurality of round tubes 7. During the upward movement of the mesh plate 13, it comes into contact with the activated carbon rods 5. At this time, the mesh plate 13 has an upward lifting force on the activated carbon rods 5, causing the disc 9 to lift upward outside the pipe fitting 6. When the position of the disc 9 is lifted, the plate body 23 outside the pipe fitting 6 moves upward in the vertical groove 22 inside the disc 9. At the same time, since the plate body 23 comes into contact with the vertical groove 22 during rotation, when the position of the disc 9 is lifted, it can still rotate. During the rotation process, the activated carbon rods 5 roll on the surface of the mesh plate 13, so that the outer surface of the activated carbon rods 5 evenly adsorbs the suspended substances and colloids on the surface of the mesh plate 13.

[0055] During the dispensing process, the problem of infiltration will occur, and it is necessary to add an anti-seepage agent to the glue to inhibit this situation. However, on the premise that stirring is not allowed, the fluidity of the glue is poor, and the added anti-seepage agent cannot be evenly distributed in the glue.

[0056] For this purpose, during the upward movement of the disc 9, the second diversion holes 21 on the disc 9 will coincide with the positions of the reserved holes outside the pipe fitting 6. At this time, the anti-seepage agent previously stored inside the pipe fitting 6 enters the second diversion holes 21. Meanwhile, the annular plate 11 pushes the moving seat 18 upward, causing the second diversion holes 21 to coincide with the first diversion holes 19. The anti-seepage agent flows through the second diversion holes 21 and the first diversion holes 19 and enters the activated carbon rod 5 through the round tube 7. When the activated carbon rod 5 is in its initial state, the slot holes 8 on its outer side are at the highest position. When the activated carbon rod 5 rolls, the positions of the slot holes 8 change, and the anti-seepage agent leaks out from the slot holes 8 and falls on the mesh plate 13. As the activated carbon rod 5 rolls, the anti-seepage agent is evenly smeared on the mesh plate 13. It should be noted that after the activated carbon rod 5 adsorbs the colloid and suspended matter, during the process of continuing to contact the mesh plate 13, it will not throw out the adsorbed colloid and suspended matter. This is because activated carbon has a huge specific surface area and a rich pore structure, and can adsorb impurities through the van der Waals force between molecules. Once the impurities are adsorbed on the activated carbon, they will not be easily desorbed.

[0057] When the mesh plate 13 is about to reach the highest point, the stepping motor 42 is started to reverse, driving the mesh plate 13 to descend. Since the mesh plate 13 is in a porous state, the anti-seepage agent forms a thin film on the surface of the mesh plate 13. At the same time, the anti-seepage agent can adhere to the inner sides of the mesh holes on the mesh plate 13, which also increases the area of distribution of the anti-seepage agent and also increases the contact area with the glue. When the mesh plate 13 descends and contacts the glue, the glue contacts the anti-seepage agent in the sieve holes. Due to the increased contact area, the collision probability between the molecules of the two liquids increases, and the mixing rate will also increase accordingly, enabling the anti-seepage agent to be evenly diffused into the glue.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
