Description

Technical Field

[0001] The utility model relates to the technical field of dust removal of reinforcement plates, in particular to automatic dust removal equipment for FR4 reinforcement plates. Background Art

[0002] FPC flexible circuit board is a kind of flexible printed circuit board with high reliability made of polyimide or polyester film as the base material. Since FPC flexible circuit board has low mechanical strength and is easy to crack, it needs to be bonded with reinforcing materials to enhance the strength of FPC. FR4 reinforcing plate is a material used to reinforce flexible circuit boards. It mainly solves the flexibility of flexible circuit boards, improves the strength of the plug-in parts, and facilitates the overall assembly of the product.

[0003] In the production and processing of FR4 reinforcing plates, dust is inevitably attached to the surface of the reinforcing plates. In order to prevent the dust on the surface of the reinforcing plates from affecting the later lamination effect, it is generally necessary to perform dust removal operations before lamination. However, existing reinforcing plate dust removal equipment usually uses a brush roller to wipe the dust on the surface of the reinforcing plates. However, since the dust easily floats into the air and the surface of the brush roller cannot be cleaned at any time during the cleaning process, the dust removal effect on the reinforcing plates is limited. Therefore, an automatic dust removal device for FR4 reinforcing plates is proposed. Utility Model Content

The utility model provides an automatic dust removal device for FR4 reinforcement plates.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

Two groups of The positioning assembly 10 for positioning and fixing the reinforcing steel sheet, and the two ends of the base 1 are respectively provided with an unwinding machine 11 and a winding machine 12 for unwinding and winding the reinforcing steel sheet.

The unwinding assembly 7 moves synchronously to a suitable position, so that the sticky paper 9 wound on the unwinding assembly 7 can fit with the reinforcement plate passing the surface of the conveyor belt 2. Since the rewinder 12 continuously rewinds the reinforcement plate, the unwinder 11 continuously unwinds the reinforcement plate, and the unwinding assembly 7 and the rewinding assembly 8 also continuously unwind and rewind the sticky paper 9. The sticky paper 9 wound on the unwinding assembly 7 also continuously contacts the reinforcement plate while unwinding, so that the sticky paper 9 is used to stick the dust on the surface of the reinforcement plate. At the same time, the hydraulic rod 3 also cooperates to drive the connecting block 5, the inclined plate 6, the unwinding assembly 7, and the rewinding assembly 8 to move downward synchronously. The unwinding assembly 7 and the winding assembly 8 are moved so that the sticky paper 9 wound on the unwinding assembly 7 can always keep in contact with the reinforcing plate. If the reinforcing plate cannot be rolled into a tube, the reinforcing plate can be laid flat on the surface of the conveyor belt 2, and the driving assembly 4 is used to drive the hydraulic rod 3 to perform a linear reciprocating motion along the side of the base 1. Every time the driving assembly 4 drives the hydraulic rod 3 to perform a linear reciprocating motion, the unwinding assembly 7 and the winding assembly 8 unwind and rewind the sticky paper 9. At the same time, the hydraulic rod 3 also cooperates to drive the connecting block 5, the inclined plate 6, the unwinding assembly 7, and the winding assembly 8 to move downward synchronously, so that the reinforcing plate laid flat on the surface of the conveyor belt 2 can be cleaned of dust sticking.

The two ends of the sticky paper 9 are respectively wound on the unwinding shaft 72 and the winding shaft 82. It should be noted that the servo motor 71 can drive the unwinding shaft 72 to rotate at a preset angle and speed, thereby unwinding the sticky paper 9 wound on the unwinding shaft 72, and the servo motor 81 can drive the winding shaft 82 to rotate at a preset angle and speed, thereby winding the sticky paper 9 wound on the winding shaft 82.

[0024] like Figure 1 As shown, the driving assembly 4 includes a rectangular frame 41, a rectangular frame 41 is fixedly installed on the side of the base 1, a servo motor 42 is fixedly installed at one end of the rectangular frame 41, the output end of the servo motor 42 extends to the inside of the rectangular frame 41 and is fixedly connected to a threaded rod 43, a movable block 44 is threadedly connected to the threaded rod 43, the movable block 44 is movably installed in the inside of the rectangular frame 41, a mounting plate 45 is fixedly installed on the side of the movable block 44 away from the base 1, and a hydraulic rod 3 is fixedly installed on the top of the mounting plate 45.

[0025] like Figure 1 , Figure 3 As shown, the positioning assembly 10 includes a U-shaped frame 101, and two groups of U-shaped frames 101 are arranged on the top of the base 1, a rectangular plate 102 is fixedly installed on one side of each U-shaped frame 101, a servo motor three 103 is fixedly installed on the top of each rectangular plate 102, and the output end of each servo motor three 103 extends to the inside of the corresponding U-shaped frame 101 and is fixedly connected with a bidirectional screw rod 104, and both ends of each bidirectional screw rod 104 are respectively threadedly connected with a positioning block 105, and a limit rod 106 is fixedly installed inside each U-shaped frame 101, and each limit rod 106 passes through the corresponding two positioning blocks 105. It should be noted that the servo motor three 103 can drive the corresponding bidirectional screw rod 104 to reciprocate at a preset angle and speed, so that the corresponding two positioning blocks 105 are close to or away from each other until they move to a suitable position, so that the reinforcement plate passing through the surface of the conveyor belt 2 passes through the middle of the two adjacent positioning blocks 105 respectively, thereby preventing the reinforcement plate from being offset.

Each slider 109 is movably installed inside the adjacent slide groove 108. It should be noted that if the reinforcement plate cannot be rolled into a cylindrical shape, the two U-shaped frames 101 can be moved after the reinforcement plate is laid flat on the surface of the conveyor belt 2. Each U-shaped frame 101 drives the corresponding two hydraulic rods 2 1010 and the two sliders 109 to slide inside the corresponding slide groove 108 respectively, until the two U-shaped frames 101 are moved to the appropriate positions, and each adjacent two positioning blocks 105 are also moved to the appropriate positions, each hydraulic rod 2 1010 drives the U-shaped frame 101 to move downward, and at this time, each positioning block 105 moves downward synchronously, and the reinforcement plate laid flat on the surface of the conveyor belt 2 is pressed and fixed by four positioning blocks 105.

[0028] In summary:

[0029] First, the reinforcing plate rolled into a tube is sleeved on the unwinding machine 11, and then the free end of the reinforcing plate is wound on the winding machine 12, and the reinforcing plate passing through the surface of the conveyor belt 2 passes under the two positioning components 10, and the positioning components 10 are used to prevent the reinforcing plate from deflecting. In advance, the hydraulic rod 3 drives the connecting block 5 to move upward or downward to a suitable position, and the connecting block 5 drives the unwinding component 7 and the winding component 8 to move to a suitable position synchronously through the inclined plate 6, so that the sticky paper 9 wound on the unwinding component 7 can fit with the reinforcing plate passing through the surface of the conveyor belt 2. Since the winding machine 12 continuously winds the reinforcing plate, the unwinding machine 11 continuously unwinds the reinforcing plate, and the unwinding component 7 and the winding component 8 also continuously unwind and rewind the sticky paper 9, the sticky paper 9 wound on the unwinding component 7 is unwound while It also keeps in contact with the reinforcing plate, so that the dust on the surface of the reinforcing plate is pasted away by the sticky paper 9. At the same time, the hydraulic rod 3 also cooperates to drive the connecting block 5, the inclined plate 6, the unwinding assembly 7, and the winding assembly 8 to move downward synchronously, so that the sticky paper 9 wound on the unwinding assembly 7 can always keep in contact with the reinforcing plate. If the reinforcing plate cannot be rolled into a tube, the reinforcing plate can be flattened on the surface of the conveyor belt 2. The driving assembly 4 is used to drive the hydraulic rod 3 to perform a linear reciprocating motion along the side of the base 1. Every time the driving assembly 4 drives the hydraulic rod 3 to perform a linear reciprocating motion, the unwinding assembly 7 and the winding assembly 8 unwind and rewind the sticky paper 9. At the same time, the hydraulic rod 3 also cooperates to drive the connecting block 5, the inclined plate 6, the unwinding assembly 7, and the winding assembly 8 to move downward synchronously, so that the reinforcing plate laid on the surface of the conveyor belt 2 can be cleaned of dust sticking.
