DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1, reference Figure 1-2 A desktop automatic glue dispensing machine includes a glue dispensing machine body 1 and a frame 2. A feed barrel 3 is arranged on the frame 2. A mesh plate 13 is movably arranged inside the feed barrel 3. In an initial state, the mesh plate 13 is located at the bottom of the feed barrel 3.

[0029] Reference Fig. 9 A pipe fitting 6 is installed on the top of the threaded rod 10, a disc 9 is slidably arranged on the outside of the pipe fitting 6, a plate body 23 is arranged on the outside of the pipe fitting 6, a vertical groove 22 is arranged on the inner side of the disc 9, and the plate body 23 slides in the vertical groove 22, and a chassis 20 is installed on the top of the outer side of the supply barrel 3.

[0030] Reference Figure 7 The top of the pipe fitting 6 extends into the chassis 20, and a transmission assembly 4 is arranged at the top of the pipe fitting 6. The transmission assembly 4 includes a first transmission tooth 41, a stepper motor 42 and a second transmission tooth 43. The second transmission tooth 43 is arranged at the end of the output shaft of the stepper motor 42. The stepper motor 42 is installed on the top of the chassis 20. The first transmission tooth 41 is installed on the pipe fitting 6, and the first transmission tooth 41 and the second transmission tooth 43 are meshed with each other.

[0031] A threaded rod 10 is provided at the center of the bottom of the feed barrel 3 , a threaded sleeve 12 is installed at the center of the mesh plate 13 , the threaded rod 10 penetrates the threaded sleeve 12 , and the threaded sleeve 12 and the threaded rod 10 cooperate with each other.

[0032] Reference Figure 8 A guide assembly 14 is arranged between the mesh plate 13 and the inner wall of the feed barrel 3. The guide assembly 14 includes a guide rail 141 and a connecting block 142. The guide rail 141 is vertically opened in the feed barrel 3. The connecting block 142 is connected to the side wall of the mesh plate 13. The connecting block 142 is slidably arranged in the guide rail 141. When the mesh plate 13 is about to reach the highest point, the activated carbon rod 5 will rotate at the upper end position of the mesh plate 13.

[0033] A conveying crawler is provided on the base of the dispensing machine body 1, and the object to be processed is placed on the upper end for position control. At the same time, the frame 2 can move in the horizontal direction, and the dispensing head can adjust the height. The dispensing machine is a commonly used dispensing equipment on the existing market, and no further details will be given here.

[0034] After the glue is injected into the feed barrel 3 through the pump body, during the actual operation of the equipment, the glue head is often blocked, the glue is broken and tailing occurs due to impurities in the glue. The impurities in the glue are suspended by stirring and then filtered, which will increase the number of bubbles in the glue.

[0035] To this end, the power output of the stepper motor 42 is used to drive the first transmission tooth 41 and the second transmission tooth 43 to rotate, and the kinetic energy is transferred 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, it will form a screw structure 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. The connecting block 142 cooperates with the guide rail 141 on the feed box 3 to provide a guiding effect for the mesh plate 13. During the movement of the mesh plate 13 to the upper end, after the impurities contact 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, thereby avoiding the problem of these substances entering the dispensing head and causing blockage.

[0036] Example 2, reference Figure 3-5 The difference between this embodiment and embodiment 1 is that an adsorption assembly is arranged above the mesh plate 13, and the adsorption assembly includes an activated carbon rod 5, a circular tube 7, a slot 8 and a disc 9. The circular tube 7 is rotatably arranged between the disc 9 and the activated carbon rod 5, and the interior of the activated carbon rod 5 is hollow. The slot 8 is opened on the outer surface of the activated carbon rod 5 along the axial direction of the activated carbon rod 5, and the interior of the activated carbon rod 5 is connected to the interior of the disc 9 through the circular tube 7.

[0037] When these suspended matter and colloid are located at the upper end of the mesh plate 13, they need to be collected and transferred in a timely manner.

[0038] To this end, activated carbon rods 5 are rotatably arranged on the outside of the disc 9 through multiple circular tubes 7. When the mesh plate 13 rises, it contacts the activated carbon rods 5. At this time, the mesh plate 13 has an upward lifting force on the activated carbon rods 5, so that the disc 9 is lifted upward on the outside of the pipe 6. When the position of the disc 9 is lifted, the plate body 23 on the outside of the pipe 6 moves upward in the vertical groove 22 inside the disc 9. At the same time, since the plate body 23 contacts the vertical groove 22 during rotation, the disc 9 can still rotate when it is lifted. During the rotation, 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 matter and colloid on the surface of the mesh plate 13.

[0039] Example 3, reference Figure 6The difference between this embodiment and embodiment 1 and embodiment 2 is that the inner side of the pipe 6 is filled with an anti-seepage agent, a plurality of second diversion holes 21 are evenly provided on the disc 9, and the second diversion holes 21 correspond to the reserved hole positions on the pipe 6 one by one, a plurality of longitudinal chambers 17 are evenly provided inside the disc 9, and an adjustment component is provided on the inner side of the chamber 17, and the adjustment component includes an elastic column 16, a movable seat 18 and a first diversion hole 19; the movable seat 18 slides in the chamber 17, and the first diversion hole 19 is through-opened on the movable seat 18, an elastic column 16 is also provided between the top of the chamber 17 and the movable seat 18, and the first diversion hole 19 and the second diversion hole 21 correspond to each other.

[0040] refer to Figure 4-5 An annular groove 15 is provided at the bottom of the disc 9, and the annular groove 15 is communicated with a plurality of chambers 17. An annular plate 11 is installed on the top of the threaded sleeve 12. In the initial state, the first diversion hole 19 and the second diversion hole 21 do not overlap with each other. When the annular plate 11 rises to the highest point, the annular plate 11 pushes the moving seat 18 upward, and at this time, the first diversion hole 19 and the second diversion hole 21 overlap with each other.

[0041] During the dispensing process, the problem of contamination will occur, and it is necessary to add an anti-seepage agent to the glue to suppress the occurrence of this situation. However, under the premise that it cannot be stirred, the fluidity of the glue is poor and the added anti-seepage agent cannot be evenly spread in the glue.

[0042] Therefore, during the rising process of the disc 9, the second diverter hole 21 on the disc 9 will overlap with the reserved hole position on the outer side of the pipe 6. At this time, the anti-seepage agent previously stored in the pipe 6 enters the second diverter hole 21. At the same time, the annular plate 11 pushes the movable seat 18 upward, so that the second diverter hole 21 and the first diverter hole 19 overlap each other. The anti-seepage agent flows along the second diverter hole 21 and the first diverter hole 19 through the circular tube 7 into the activated carbon rod 5. In the initial state of the activated carbon rod 5, the slot 8 on the outer side is located at the highest point. When the activated carbon rod 5 rolls, , causing the position of the slot 8 to change, the anti-seepage agent leaks out of the slot 8 and falls on the mesh 13, and as the activated carbon rod 5 rolls, the anti-seepage agent is evenly applied to the mesh 13. It should be noted that after the activated carbon rod 5 adsorbs the colloid and the suspended matter, it continues to contact with the mesh 13 and will not throw out the adsorbed colloid and the suspended matter. This is because the activated carbon has a huge specific surface area and 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.

[0043] When the mesh plate 13 is about to reach the highest point, the stepper motor 42 is started to reverse and drive the mesh plate 13 to descend. Since the mesh plate 13 is porous, 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 side of the mesh holes on the mesh plate 13, which increases the distribution area of ​​the anti-seepage agent and 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 increase in the contact area, the collision probability between the two liquid molecules increases, and the mixing rate will also increase accordingly, so that the anti-seepage agent can be evenly diffused into the glue.

[0044] The working principle of the device is: A conveying crawler is provided on the base of the dispensing machine body 1, and the object to be processed is placed on the upper end for position control. At the same time, the frame 2 can move in the horizontal direction, and the dispensing head can adjust the height. The dispensing machine is a commonly used dispensing equipment on the existing market. Its working principle and model will not be elaborated here.

[0045] After the glue is injected into the feed barrel 3 through the pump body, during the actual operation of the equipment, the glue head is often blocked, the glue is broken and tailing occurs due to impurities in the glue. The impurities in the glue are suspended by stirring and then filtered, which will increase the number of bubbles in the glue.

[0046] To this end, the power output of the stepper motor 42 is used to drive the first transmission tooth 41 and the second transmission tooth 43 to rotate, and the kinetic energy is transferred 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, it will form a screw structure 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. The connecting block 142 cooperates with the guide rail 141 on the feed box 3 to provide a guiding effect for the mesh plate 13. During the movement of the mesh plate 13 to the upper end, after the impurities contact 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, thereby avoiding the problem of these substances entering the dispensing head and causing blockage.

[0047] When these suspended matter and colloid are located at the upper end of the mesh plate 13, they need to be collected and transferred in a timely manner.

[0048] To this end, activated carbon rods 5 are rotatably arranged on the outside of the disc 9 through multiple circular tubes 7. When the mesh plate 13 rises, it contacts the activated carbon rods 5. At this time, the mesh plate 13 has an upward lifting force on the activated carbon rods 5, so that the disc 9 is lifted upward on the outside of the pipe 6. When the position of the disc 9 is lifted, the plate body 23 on the outside of the pipe 6 moves upward in the vertical groove 22 inside the disc 9. At the same time, since the plate body 23 contacts the vertical groove 22 during rotation, the disc 9 can still rotate when it is lifted. During the rotation, 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 matter and colloid on the surface of the mesh plate 13.

[0049] During the dispensing process, the problem of contamination will occur, and it is necessary to add an anti-seepage agent to the glue to suppress the occurrence of this situation. However, under the premise that it cannot be stirred, the fluidity of the glue is poor and the added anti-seepage agent cannot be evenly spread in the glue.

[0050] Therefore, during the rising process of the disc 9, the second diverter hole 21 on the disc 9 will overlap with the reserved hole position on the outer side of the pipe 6. At this time, the anti-seepage agent previously stored in the pipe 6 enters the second diverter hole 21. At the same time, the annular plate 11 pushes the movable seat 18 upward, so that the second diverter hole 21 and the first diverter hole 19 overlap each other. The anti-seepage agent flows along the second diverter hole 21 and the first diverter hole 19 through the circular tube 7 into the activated carbon rod 5. In the initial state of the activated carbon rod 5, the slot 8 on the outer side is located at the highest point. When the activated carbon rod 5 rolls, , causing the position of the slot 8 to change, the anti-seepage agent leaks out of the slot 8 and falls on the mesh 13, and as the activated carbon rod 5 rolls, the anti-seepage agent is evenly applied to the mesh 13. It should be noted that after the activated carbon rod 5 adsorbs the colloid and the suspended matter, it will not throw out the adsorbed colloid and the suspended matter during the process of continuing to contact with the mesh 13. This is because the activated carbon has a huge specific surface area and 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.

[0051] When the mesh plate 13 is about to reach the highest point, the stepper motor 42 is started to reverse and drive the mesh plate 13 to descend. Since the mesh plate 13 is porous, 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 side of the mesh holes on the mesh plate 13, which increases the distribution area of ​​the anti-seepage agent and 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 increase in the contact area, the collision probability between the two liquid molecules increases, and the mixing rate will also increase accordingly, so that the anti-seepage agent can be evenly diffused into the glue.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
