[0031] Specifically, by starting the second motor 30, under the action of the output end of the second motor 30, the threaded block 19 is threadedly rotated along the outer wall of the first threaded rod 20, thereby driving the movement of the placement plate 6, so that circuit boards of different sizes can be moved for dispensing glue, and by starting the first motor 12, one of the second gears 9 is driven to rotate in meshing with the toothed belt 10, and at the same time, one of the first gears 8 is driven to rotate. Under the action of the toothed belt 10, the other second gear 9 meshing with the toothed belt 10 is driven to rotate, and at the same time, the other first gear 8 is driven to rotate, so that the two first gears 8 are meshed with the two racks 7, so that the two racks 7 can be raised and lowered.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The moving component includes a moving groove 5, which is opened on one side of the inner part of the placement plate 6. The outer side of the placement plate 6 is fixedly connected with a support plate 27, the top of the support plate 27 is fixedly connected with a cylinder 4, the output end of the cylinder 4 is slidably connected to the inside of the moving groove 5, the output end of the cylinder 4 is fixedly connected with a sliding column 13, the bottom of the sliding column 13 is fixedly connected with a conveying block 26, the outer side of the conveying block 26 is rotatably connected with two rollers 15, and the inner bottom of the conveying block 26 is threadedly connected with a threaded dispensing head 25.

[0033] Specifically, under the action of the moving component, the glue dispensing machine can accurately dispense glue at different positions on the circuit board. The output end of the cylinder 4 slides inside the moving groove 5, so that the cylinder 4 can be more stable during operation. By starting the cylinder 4, under the action of the output end of the cylinder 4, the sliding column 13 is driven to slide along the inner wall of the moving groove 5. The threaded glue dispensing head 25 can move more stably for glue dispensing through the glue dispensing groove 17. The movement coordination of the two wheel grooves 18 and the two rollers 15 allows the sliding column 13 to move more smoothly and smoothly. The sliding column 13 is a telescopic sliding column. When different glue dispensing heads need to be replaced, other glue heads can be replaced to dispense glue on the circuit board by twisting the threaded glue dispensing head 25.

[0034] Reference Figure 1 and Figure 4 The bottom of the placement plate 6 is fixedly connected to two telescopic rods 14, the bottom of the telescopic rod 14 is fixedly connected to a lifting plate 16, the outer side of the lifting plate 16 is provided with two rotating wheel grooves 18, and the outer side of the lifting plate 16 is provided with a glue groove 17.

[0035] Specifically, the telescopic rod 14 makes the lifting plate 16 more solid and prevents the lifting plate 16 from falling off. The wheel groove 18 provides a moving platform for the roller 15 so that the roller 15 can move more stably. The glue dispensing groove 17 provides a sliding platform for the conveying block 26 so that the conveying block 26 can slide stably.

[0036] Reference Figure 1 The outer side of the mounting base plate 1 is fixedly connected with a slide rod 2, and the outer side of the slide rod 2 is slidably connected with a slide plate 3.

[0037] Specifically, the sliding plate 3 moves along the outer wall of the sliding rod 2, so that the placement plate 6 can move smoothly.

[0038] Reference Figure 1 Two limit blocks 22 are fixedly connected to the top of the installation base plate 1, the inner part of the limit block 22 is rotatably connected to the second threaded rod 21, and the outer side of the second threaded rod 21 is threadedly connected to the threaded clamping plate 23.

[0039] Specifically, under the action of the limit block 22, the circuit board is consolidated to glue the circuit board, and the second threaded rod 21 can effectively play its threaded role, thereby driving the movement of the threaded clamp 23, so as to better fix the circuit board and can fix circuit boards of different sizes.

[0040] Reference Figure 4 Two auxiliary rods 29 are fixedly connected to the inside of the placement plate 6, and the outer side of the auxiliary rod 29 is rotatably connected to the third gear 28.

[0041] Specifically, the auxiliary rod 29 provides a mounting platform for the third gear 28 , and under the action of the third gear 28 , the rack 7 can be supported more stably when the lifting of the rack 7 stops.

[0042] Reference Figure 3 and Figure 4 The inner side of the toothed belt 10 is meshedly connected with the two second gears 9 , the outer side of the second gears 9 is fixedly connected with the outer side of the transmission rod 11 , and the outer side of the transmission rod 11 is also fixedly connected with one of the first gears 8 .

[0043] Specifically, by rotating one of the second gears 9, the toothed belt 10 is driven to rotate, thereby driving the rotation of another second gear 9, so that the second gear 9 drives the rotation of one of the first gears 8, so that the other rack 7 moves. This approach reduces the use of motors and saves equipment costs.

[0044] Reference Figure 1 and Figure 4 The top of the sliding column 13 is slidably connected to the inside of the moving groove 5, the two rollers 15 are rotatably connected to the inside of the two rotating wheel grooves 18, and the conveying block 26 is slidably connected to the inside of the glue dispensing groove 17.

[0045] Specifically, the movable groove 5 provides a stable platform and a sliding platform for the sliding column 13. The cooperation between the two rollers 15 and the two rotating wheel grooves 18 allows the upper layer to operate more stably. Under the action of the glue dispensing groove 17, the conveying block 26 can operate more stably, sharing some pressure for the movable groove 5.

[0046] Working principle: When it is necessary to dispense glue on the circuit board, the second motor 30 is started at this time. Under the action of the output end of the second motor 30, the threaded block 19 is threadedly rotated along the outer wall of the first threaded rod 20, and the sliding plate 3 is moved along the outer wall of the sliding rod 2, thereby driving the movement of the placement plate 6, so that circuit boards of different sizes can be dispensed. When the staff needs to adjust the height of the glue dispenser to facilitate the dispensing of the circuit board, the first motor 12 is started to drive one of the second gears 9 to engage and rotate with the toothed belt 10. At the same time, the first motor 12 drives one of the first gears 8 to rotate. Under the action of the toothed belt 10, the other second gear 9 engaged with the toothed belt 10 is driven to rotate, and then the transmission rod 11 is driven to move. Then the transmission rod 11 drives the movement of the other first gear 8, so that the two first gears 8 are engaged with the two racks 7, so that the two racks 7 drive the lifting and lowering movement of the lifting plate 16.

[0047] In addition, when it is necessary to accurately dispense glue to the circuit board, the cylinder 4 is started at this time. Under the action of the output end of the cylinder 4, the sliding column 13 is driven to slide along the inner wall of the movable groove 5. Under the action of the glue dispensing groove 17, the threaded glue dispensing head 25 can move more stably, so as to dispense glue to the circuit board. Under the movement coordination of the two rotating wheel grooves 18 and the two rollers 15, the sliding column 13 can move more smoothly and smoothly, and the stability of the sliding column 13 is maintained, so as to ensure accurate and uniform glue dispensing of the circuit board 13. When it is necessary to replace a different glue dispensing head, the threaded glue dispensing head 25 is twisted to The threaded glue dispensing head 25 is removed from the inner bottom of the conveying block 26 and then replaced. When the circuit board needs to be fixed so as to dispense glue on it stably, the two second threaded rods 21 are twisted to drive the movement of the two threaded clamps 23. When the outer surface of the threaded clamp 23 is close to the side outer surface of the circuit board, the twisting of the second threaded rod 21 is stopped to complete the fixation of the circuit board. When the dispensing is completed, the second threaded rod 21 is twisted in the opposite direction to make the outer surface of the threaded clamp 23 away from the side outer surface of the circuit board, thereby completing the disassembly of the circuit board.
