Description

Technical Field

[0001] This utility model relates to the field of electrostatic dust removal technology, and in particular to an electrostatic dust removal structure for buffer paper. Background Technology

[0002] PCB hot-pressing buffer paper is a key material in PCB manufacturing. It plays a role in buffering and evenly distributing pressure during the hot-pressing stage, thereby ensuring the quality and consistency of PCB lamination.

[0003] When processing PCB hot-pressing cushioning paper separately, surface cleaning before cutting is a critical step. Its main function is to remove surface dust, fibers, and hard particles to ensure smooth, burr-free cut edges and improve dimensional accuracy. Furthermore, the cleaning process effectively reduces damage to the cutting blades from impurities, extends equipment lifespan, and maintains processing stability. Cleaned cushioning paper has a more uniform thickness distribution, preventing uneven pressure or contaminant transfer from affecting product quality during subsequent PCB hot pressing, ultimately ensuring the efficiency and reliability of the hot pressing process.

[0004] In the existing cleaning process for PCB hot-pressing buffer paper, the conventional procedure involves initial cleaning with a double-roller brush, followed by electrostatic dust removal using two opposing ionizers. These ionizers are located on either side of the buffer paper, with their outlets facing inwards (towards the buffer paper surface). While this arrangement improves dust removal efficiency, over long-term use, the outlets of the ionizers tend to accumulate debris, leading to blockages. Furthermore, the opposing installation design of the two ionizers, with their outlets facing the narrow gaps in the buffer paper, severely restricts the cleaning space, significantly increasing maintenance difficulty and operational inconvenience. Utility Model Content

[0005] This invention is a buffer paper electrostatic dust removal structure proposed to overcome the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a buffer paper electrostatic dust removal structure, including a frame, wherein a bidirectional moving component is symmetrically fixedly connected to one side of the top of the frame, and two connecting rods are rotatably connected to the two movable ends of the bidirectional moving component, and a sliding seat is rotatably connected to the other end of the four connecting rods.

[0007] Each of the four slides is provided with a mounting base, and the four mounting bases are in pairs. The two mounting bases in the same group can be detachably and fixedly installed with an ion air bar.

[0008] An adjustment assembly is fixedly installed on one side of the outer surface of the frame. Both ends of the adjustment assembly are slidably connected to movable rods, which pass through adjacent slide seats and are slidably connected to them. Both movable rods are connected to adjacent mounting seats by a transmission assembly.

[0009] Furthermore, the bidirectional moving assembly includes a bearing housing, which is fixedly connected to the frame. The inner ring of the bearing housing is fixedly connected to a bidirectional screw. Two movable plates are symmetrically threaded on the outer surface of the bidirectional screw, and the movable plates are rotatably connected to two adjacent connecting rods. The bearing housing provides support for the bidirectional screw, which facilitates the installation of the bidirectional screw.

[0010] Furthermore, a first handwheel is fixedly connected to one end of the bidirectional screw, which facilitates manual driving of the bidirectional screw to rotate.

[0011] Furthermore, the outer surface of the frame is provided with stroke holes that extend into the interior on both sides, and the slide is slidably connected to the stroke holes. The stroke holes limit the movement of the slide and ensure the stability of the slide movement.

[0012] Furthermore, the adjustment assembly includes a fixed base, which is fixedly connected to the frame. A second handwheel is fixedly connected to one side of the fixed base, and a one-way screw is fixedly connected to one side of the outer surface of the second handwheel. The one-way screw passes through the fixed base and is rotatably connected to the fixed base. A movable sleeve is threaded onto the outer surface of the one-way screw, and the movable sleeve slides onto the outer surface of two movable rods, enabling the two movable rods to move synchronously.

[0013] Furthermore, both of the aforementioned transmission components include racks, and the racks are fixedly connected to the movable rods. A gear is meshed with one side of the outer surface of the rack, and the gear is fixedly connected to an adjacent mounting base. The rack and pinion transmission has high transmission accuracy and reliability, which can ensure the accuracy and stability of angle adjustment.

[0014] The beneficial effects of this utility model are:

[0015] In use, this utility model provides an electrostatic dust removal structure for buffer paper. Through the arrangement of a bidirectional one-end component, connecting rod, slide, mounting base, adjustment component, movable rod, and transmission component, it can not only easily adjust the distance between the two ion air bars to accommodate buffer paper of different thicknesses, but also adjust the orientation of the air outlet of the ion air bars to move them out of narrow spaces for easier cleaning, thus reducing maintenance and operation difficulties.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figs. 1 to 3 As shown, a buffer paper electrostatic dust removal structure is disclosed, including a frame 1. A bidirectional moving assembly is symmetrically fixedly connected to one side of the top of the frame 1. Two connecting rods 12 are rotatably connected to the two movable ends of the bidirectional moving assembly. The bidirectional moving assembly includes a bearing seat 2, which is fixedly connected to the frame 1. A bidirectional screw 3 is fixedly connected to the inner ring of the bearing in the bearing seat 2. Two movable plates 4 are symmetrically threaded on the outer surface of the bidirectional screw 3, and the movable plates 4 are rotatably connected to the two adjacent connecting rods 12. A first handwheel 6 is fixedly connected to one end of the bidirectional screw 3, and a slide 8 is rotatably connected to the other end of the four connecting rods 12. The thread helix angle (α) of the bidirectional screw 3 is less than the friction angle (ρ), and the screw has a self-locking capability to prevent it from shifting due to vibration or load.

[0024] Both sides of the outer surface of the frame 1 are provided with stroke holes 18 that extend into the interior, and the slide 8 is slidably connected to the stroke holes 18. The stroke holes 18 have a limiting effect on the slide 8.

[0025] Each of the four slides 8 is equipped with a mounting base 7. The four mounting bases 7 are arranged in pairs. The two mounting bases 7 in the same group can be detachably fixed to the ion air bar 5. The ion air bar 5 is fixed to the mounting base 7 with bolts, which facilitates disassembly and assembly.

[0026] An adjustment assembly is fixedly installed on one side of the outer surface of the frame 1. Both ends of the adjustment assembly are slidably connected to movable rods 10, which pass through adjacent slide blocks 8 and are slidably connected thereto. A transmission assembly is installed between each of the two movable rods 10 and adjacent mounting seats 7. The adjustment assembly includes a fixed seat 14, which is fixedly connected to the frame 1. A second handwheel 13 is fixedly connected to one side of the fixed seat 14. A one-way screw 16 is fixedly connected to one side of the outer surface of the second handwheel 13, and the one-way screw 16 passes through the fixed seat 14. The screw 16 is rotatably connected to the fixed base 14. The outer surface of the one-way screw 16 is threaded with a movable sleeve 17, and the movable sleeve 17 is slidably fitted on the outer surface of the two movable rods 10. Both transmission components include racks 15, and the racks 15 are fixedly connected to the movable rods 10. A gear 11 is meshed on one side of the outer surface of the rack 15, and the gear 11 is fixedly connected to the adjacent mounting base 7. The thread helix angle (α) of the one-way screw 16 is less than the friction angle (ρ). The screw has a self-locking capability to prevent it from shifting due to vibration or load.

[0027] Spacing adjustment: Rotating the first handwheel 6 drives the bidirectional screw 3 to rotate, and through the threaded transmission, the two movable plates 4 move towards each other or away from each other. The movable plates 4 push the slide 8 to slide synchronously along the stroke hole 18 through the connecting rod 12, which drives the two sets of mounting seats 7 to realize the symmetrical opening and closing movement of the ion air bar 5, adapting to buffer paper of different thicknesses.

[0028] Angle adjustment: Rotating the second handwheel 13 causes the one-way screw 16 to rotate, driving the movable sleeve 17 to move axially. The movable sleeve 17 pushes the movable rods 10 on both sides to slide synchronously. The movable rods 10 are driven by the meshing of the rack 15 and the gear 11, forcing the mounting base 7 to rotate within the slide 8. This ultimately achieves the joint adjustment of the outlet angle of the ion air bar 5, which optimizes the dust removal effect and provides convenience for maintenance operations.

[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
