Description

Technical Field

[0001] This utility model relates to the field of roller plate threading technology, and in particular to a roller plate threading device for conveying rollers in circuit board cleaning lines. Background Technology

[0002] The conveyor rollers in a circuit board cleaning line are key equipment for the efficient transfer of circuit boards, and their design ensures stable movement of the boards during the cleaning process. Employing a roller-shaft-through device, where the central shaft passes through multiple rollers, provides more even support, reduces friction and wear, and effectively prevents damage to the circuit boards. Furthermore, this structure helps improve conveying efficiency and automation, ensuring a smooth and consistent cleaning process, thereby enhancing overall production quality and efficiency.

[0003] Traditional circuit board cleaning lines utilize a conveyor roller system where a central shaft is inserted through multiple rollers, forming a roller system. These rollers are fixed to the shaft, and as the shaft rotates, they propel the circuit boards smoothly along the cleaning line. During cleaning, the circuit boards are evenly supported by these rollers, reducing friction and damage while ensuring stable movement in the cleaning solution. This device achieves efficient operation and automated production of the cleaning line by using the rotation of the rollers to smoothly move the circuit boards.

[0004] Traditional conveyor roller inserting devices typically rely on manual insertion of the rollers onto the outer wall of the central shaft, followed by manual adjustment of the spacing. This makes it difficult to achieve precise spacing control and lacks an automated positioning device, resulting in unstable roller positions. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a conveyor roller plate threading device for circuit board cleaning lines, which aims to improve the problem that traditional conveyor roller plate threading devices are difficult to achieve precise spacing control and lack automated positioning devices, resulting in unstable roller plate positions.

[0011] Furthermore, the linkage component includes a rack, the upper surface of which is fixedly connected to the lower surface of the triangular snap-fit ​​plate, and the rack is rotatably connected inside the push plate, the rack meshing with a gear.

[0012] Furthermore, each of the lower limiting plate and the upper limiting plate is provided with a locking hole at one end, which is used to position one end of the central shaft.

[0024] 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.

[0025] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a conveying roller plate through-shaft device for a circuit board cleaning line, including a fixed bracket 1. A roller plate placement chamber 2 is fixedly connected to the upper surface of the fixed bracket 1. Heated roller plates can be placed in the roller plate placement chamber 2, which facilitates the picking and placing of the roller plates by a robotic arm 3. A robotic arm 3 is provided on the upper surface of the fixed bracket 1. The robotic arm 3 delivers the roller plates inside the roller plate placement chamber 2 to the interior of the lower limiting plate 4. A lower limiting plate 4 is fixedly connected to the middle of the upper surface of the fixed bracket 1. A fixed frame 5 is fixedly connected to one side of the lower limiting plate 4. A pressing component is provided on the outer wall of the fixed frame 5. The pressing component is used to fix the roller plates. A cylinder 2 9 is fixedly connected to the upper surface of the fixed bracket 1. A push plate 10 is fixedly connected to the output end of the cylinder 2 9. Starting the cylinder 2 9 drives the push plate 10 and one end of the central shaft to move. A guide component is provided on the lower surface of the push plate 10. The guide component is used to guide the movement of the push plate 10.

[0026] The pressing component includes a cylinder 6, the outer wall of which is fixedly connected to the outer wall of the fixed frame 5. The output end of the cylinder 6 is fixedly connected to an upper limiting plate 7, which is in contact with a lower limiting plate 4. When the cylinder 6 is activated, it drives the upper limiting plate 7 to move downward, thereby causing the upper limiting plate 7 to slide on the outer wall of the fixed frame 5 and to fit with the lower limiting plate 4. At this time, the pre-set grooves inside the upper limiting plate 7 and the lower limiting plate 4 facilitate the fixing of the roller piece and also form a complete locking hole 8. The guiding component includes a slider 11, the upper surface of which is fixedly connected to the lower surface of the push plate 10. The slider 11 is slidably connected to a guide rail 12. When the push plate 10 moves, it will drive the slider 11 to slide on the outer wall of the guide rail 12, thereby guiding the slider 11 and the push plate 10 through the guide rail 12.

[0027] Reference Figure 3An electric push rod 13 is fixedly connected inside the push plate 10. A connecting block 14 is fixedly connected to the inner end of the electric push rod 13. A triangular locking plate 15 is fixedly connected to the lower surface of the connecting block 14. The outer wall of the triangular locking plate 15 is slidably connected to the inside of the push plate 10. An elastic rubber sheet 16 is fixedly connected to one side of the outer wall of the triangular locking plate 15. When the electric push rod 13 is activated, the connecting block 14 moves, thereby causing the triangular locking plate 15 and the elastic rubber sheet 16 on one side to slide inside the push plate 10. A linkage component is provided on the lower surface of the triangular locking plate 15. The linkage component is used to drive the triangular locking plate 15 on the other side to move synchronously. The linkage component includes a rack 17. The upper surface of the rack 17 is fixedly connected to the lower surface of the triangular locking plate 15. The rack 17 is rotatably connected inside the push plate 10. The rack 17 meshes with a gear 18 and is connected to the triangular locking plate 15. The movement of the connecting plate 15 drives the rack 17 to move. The meshing of the rack 17 and the gear 18 causes the gear 18 to rotate as the rack 17 moves. The rotation of the gear 18 then drives the rack 17 on the other side to move with the triangular locking plate 15. This causes the triangular locking plates 15 on both sides to move relative to the elastic rubber sheet 16, thus fixing the central shaft. One end of the lower limiting plate 4 and the upper limiting plate 7 is provided with a locking hole 8, which is used to position one end of the central shaft. One side of the outer wall of the upper limiting plate 7 is slidably connected to the outer wall of the fixing frame 5. The fixing frame 5 is used to guide the upper limiting plate 7. The lower surface of the guide rail 12 is fixedly connected to the upper surface of the fixing bracket 1. The guide rail 12 is used to guide the slider 11. The top of the fixing bracket 1 is provided with a central shaft placement chamber 19, which is used to place the central shaft.

[0028] Working principle: When the conveyor rollers of the circuit board cleaning line need to be used, the rollers are first soaked in hot water, and then placed inside the roller placement chamber 2. At this time, the robot arm 3 places the rollers inside the roller placement chamber 2 into the preset grooves inside the slots 8 as needed. After placement, the cylinder 6 is activated to drive the upper limit plate 7 to slide on the outer wall of the fixed frame 5, so that the upper limit plate 7 and the lower limit plate 4 are in contact. At this time, the slots 8 at one end of the lower limit plate 4 and the upper limit plate 7 match to form a complete circular groove. Then, one end of the central shaft is placed inside the slot 8, and the other end of the central shaft is placed in the preset groove inside the push plate 10. Then, the electric push rod 13 is activated. The connecting block 14 and the triangular locking plate 15 move inside the push plate 10. At this time, the movement of the triangular locking plate 15 drives the rack 17 to move, which in turn drives the gear 18 to rotate. Then, the rotation of the gear 18 drives the rack 17 and the triangular locking plate 15 on the other side to move. At this time, the triangular locking plates 15 on both sides drive the elastic rubber sheet 16 to move relative to each other to clamp and fix the central shaft. Finally, the cylinder 2 9 is activated to drive the push plate 10 and one end of the central shaft to move. At the same time, the slider 11 and the guide rail 12 guide the central shaft to pass through the middle of the lower limit plate 4 and the upper limit plate 7, and then through multiple roller pieces. After passing through, the central shaft is taken out. At this time, the central hole of the roller piece gradually shrinks and is fixed on the outer wall of the central shaft.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
