[0026] This utility model proposes a grinding device.

[0027] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the grinding device includes a frame 1 and a first conveyor belt 2, a spray assembly 3, a grinding assembly, a peeling member 5, and a second conveyor belt 6 disposed on the frame 1. The first conveyor belt 2 has an inlet end 21 and an outlet end 22. The inlet end 21 is used for feeding flexible circuit boards. The spray assembly 3 and the grinding assembly are disposed around the periphery of the first conveyor belt 2. The spray assembly 3 is used to spray liquid onto the first conveyor belt 2 so that the first conveyor belt 2 can adsorb the flexible circuit boards through the liquid. The grinding assembly is used to brush the flexible circuit boards adsorbed on the first conveyor belt 2. The peeling member 5 is rotatably disposed between the outlet end 22 and the second conveyor belt 6. The peeling member 5 is used to peel the brushed flexible circuit boards onto the second conveyor belt 6 by rotation. The second conveyor belt 6 is used to transport the brushed flexible circuit boards outward.

[0028] The technical solution of this utility model uses a spray assembly 3 to spray liquid onto the first conveyor belt 2, thereby fixing the flexible circuit board by liquid adsorption. Compared with the prior art, which uses a vacuum adsorption device on the first conveyor belt 2 to fix the flexible circuit board, this avoids the wrinkling of the flexible circuit board caused by the adsorption device. In addition, the structure of the spray assembly 3 is simpler and the use and maintenance costs are lower, thereby reducing the production cost of the flexible circuit board. By using a peeling member 5 rotatably disposed between the board exit end 22 and the second conveyor belt 6, it is convenient for the peeling member 5 to peel the brushed flexible circuit board on the first conveyor belt 2 onto the second conveyor belt 6.

[0029] In this embodiment, the first conveyor belt 2 can be used to transport flexible circuit boards, facilitating the brushing process of the flexible circuit boards and their transfer to the second conveyor belt 6. The first conveyor belt 2 has an inlet end 21 and an outlet end 22 at both ends along its conveying direction. An external feeding device can transport the flexible circuit boards from the previous process to the first conveyor belt 2 via the inlet end 21. The first conveyor belt 2 can cooperate with the peeling member 5 via the outlet end 22 to transport the brushed flexible circuit boards to the second conveyor belt 6. To facilitate the spraying assembly 3 spraying liquid onto the first conveyor belt 2, the spraying assembly 3 can be mounted on the frame 1 and located around the periphery of the first conveyor belt 2. The spraying assembly 3 sprays liquid toward the first conveyor belt 2 to wet its surface, increasing its adhesion and allowing the flexible circuit boards to be better adhered to its surface. In one embodiment, the liquid sprayed by the spraying assembly 3 can be water.

[0030] In this embodiment, to improve the processing efficiency of the grinding assembly on the flexible circuit board, the grinding assembly can be mounted on the frame 1 and located on the periphery of the first conveyor belt 2. After the first conveyor belt 2 absorbs the flexible circuit board with liquid, it transports the flexible circuit board to the grinding assembly. While the grinding assembly brushes the flexible circuit board, the first conveyor belt 2 transports the flexible circuit board along a direction close to the second conveyor belt 6. This application employs a peeling member 5 rotatably disposed between the exit end 22 and the second conveyor belt 6. When the brushed flexible circuit board is transported to the exit end 22 by the first conveyor belt 2, the peeling member 5 rotates and contacts the flexible circuit board to peel it onto the second conveyor belt 6, thereby improving the transfer efficiency of the flexible circuit board from the first conveyor belt 2 to the second conveyor belt 6. To facilitate the peeling of the flexible circuit board by the peeling member 5, the exit end 22 can be located at the arc segment of the first conveyor belt 2 close to the second conveyor belt 6, and the rotation direction of the peeling member 5 can be the same as the rotation direction of the first conveyor belt 2.

[0031] like Figure 1As shown, in one embodiment, the first conveyor belt 2 has a first position 23 for spraying liquid by the spray assembly 3 and a second position 24 for adsorbing flexible circuit boards. The spray assembly 3 is disposed on the side of the frame 1 near the first position 23, and the grinding assembly is disposed on the side of the frame 1 near the second position 24.

[0032] In this embodiment, the first position 23 and the second position 24 of the first conveyor belt 2 can be arranged on both sides of the first conveyor belt 2 in the vertical direction. The second position 24 can be arranged on the side of the first conveyor belt 2 near the inlet end 21, so as to facilitate the feeding device to feed the flexible circuit board onto the first conveyor belt 2. After the spraying assembly 3 sprays liquid onto the first conveyor belt 2, the surface of the first conveyor belt 2 carries the liquid and rotates to the second position 24, so as to facilitate the first conveyor belt 2 to adsorb the flexible circuit board.

[0033] like Figure 2 As shown, in one embodiment, the peeling member 5 includes a body 51 and a peeling portion 52 disposed on the outer peripheral wall of the body 51. The peeling portion 52 extends along the axial direction of the body 51 and is used to peel off the flexible circuit board when the peeling member 5 rotates.

[0034] In this embodiment, to improve the efficiency of the peeling member 5 in peeling the flexible circuit board from the first conveyor belt 2, this application employs a peeling part 52 extending axially along the body 51. The peeling part 52 can be configured as a soft brush. When the flexible circuit board passes through the brush and is conveyed to the output end 22, the peeling part 52 rotates and contacts the flexible circuit board, peeling it off from the first conveyor belt 2. Simultaneously, it cleans the liquid on the first conveyor belt 2, preventing uneven liquid distribution or excessive liquid accumulation that could reduce the adhesion to the flexible circuit board. In one embodiment, the peeling member 5 can also be rotated via a belt drive or other driving method. In one embodiment, the grinding device further includes a second driving member (not shown), which can be configured as a drive motor or other similar device. The second driving member drives the peeling member 5 to rotate.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the grinding device further includes a rotating shaft 7, a transmission assembly 71, and a first driving member 72. The rotating shaft 7 is connected to the first conveyor belt 2. The transmission assembly 71 is connected to the rotating shaft 7 and the stripping member 5 respectively. The first driving member 72 is connected to the transmission assembly 71 and is used to drive the transmission assembly 71 to rotate so as to drive the first conveyor belt 2 and the stripping member 5 to rotate synchronously.

[0036] In this embodiment, the transmission assembly 71 may include a first transmission member 711, a second transmission member 712, and a third transmission member 713, which may be configured as transmission gears. The first transmission member 711 is driveably connected to the rotating shaft 7, the second transmission member 712 is mounted on the frame 1, and the third transmission member 713 is driveably connected to the body 51. The second transmission member 712 is driveably connected to both the first transmission member 711 and the third transmission member 713. This application uses a first driving member 72 to drive the first transmission member 711 to rotate, thereby driving the rotating shaft 7, the first conveyor belt 2, and the second transmission member 712 to rotate. This allows the second transmission member 712 to drive the third transmission member 713 to rotate, thereby driving the peeling member 5 to rotate. This facilitates the synchronous rotation of the first conveyor belt 2 and the peeling member 5, thereby improving the efficiency of the peeling member 5 in peeling the flexible circuit board off the first conveyor belt 2.

[0037] like Figure 1 and Figure 3 As shown, in one embodiment, the spray assembly 3 includes a first pipe 31 and a first mounting bracket 32. The first mounting bracket 32 ​​is disposed on the frame 1, and the first pipe 31 is disposed on the first mounting bracket 32. The first pipe 31 has a plurality of first spray holes 311 on the side facing the first conveyor belt 2. The plurality of first spray holes 311 are spaced apart along the extension direction of the first pipe 31. The first pipe 31 is used to connect to an external water source.

[0038] In this embodiment, to improve the stability of the connection between the spray assembly 3 and the frame 1, a first pipe 31 is mounted on the frame 1 via a first mounting bracket 32. To facilitate the dripping of liquid from the first pipe 31 onto the first conveyor belt 2, the first pipe 31 is connected to an external liquid source and is positioned above the first position 23 of the first conveyor belt 2. To increase the spray area of ​​the spray assembly 3 onto the first conveyor belt 2, the first pipe 31 has multiple first spray holes 311 on the side facing the first conveyor belt 2. These multiple first spray holes 311 are spaced apart along the extension direction of the first pipe 31, thereby making the liquid distribution more uniformly sprayed onto the first conveyor belt 2. In one embodiment, the spray assembly 3 may employ an atomized spraying method to keep the surface of the first conveyor belt 2 moist.

[0039] like Figure 1 and Figure 3 As shown, in one embodiment, the spray assembly 3 further includes a regulating valve 33 connected in series with the first pipe 31, and the regulating valve 33 is used to control the flow rate of the first pipe 31.

[0040] In this embodiment, in order to control the flow rate of the first pipe 31, a regulating valve 33 is connected in series with the first pipe 31. The regulating valve 33 changes the valve core opening to achieve precise control of the liquid flow rate in the first pipe 31, thereby preventing the spray assembly 3 from spraying a large amount of liquid onto the first conveyor belt 2.

[0041] like Figure 1 As shown, in one embodiment, the grinding device further includes a pressure roller 8, which is disposed on the side of the frame 1 near the second position 24, and the pressure roller 8 is used to restrict the separation of the flexible circuit board from the first conveyor belt 2.

[0042] In this embodiment, in order to improve the stability of the flexible circuit board and the first conveyor belt 2, the present application adopts a pressure roller 8 disposed on the side of the frame 1 near the second position 24. The pressure roller 8 limits and abuts against the flexible circuit board to prevent the flexible circuit board from accidentally falling off the first conveyor belt 2 during the brushing process.

[0043] like Figure 1 As shown, in one embodiment, the pressure roller 8 is provided in multiple ways, and the multiple pressure rollers 8 are arranged along the extension direction of the first conveyor belt 2.

[0044] In this embodiment, the present application employs multiple pressure rollers 8 disposed on the side of the frame 1 near the second position 24, and the multiple pressure rollers 8 are located below the first conveyor belt 2. The multiple pressure rollers 8 are arranged along the extension direction of the first conveyor belt 2, and the multiple pressure rollers 8 limit and abut against the flexible circuit board, thereby further improving the stability of the flexible circuit board in contact with the first conveyor belt 2 throughout the brushing process.

[0045] like Figure 1 As shown, in one embodiment, the grinding assembly includes at least two grinding brushes 4, which are rotatably mounted on the frame 1. The at least two grinding brushes 4 are located on the side of the frame 1 near the second position 24, and are arranged along the extension direction of the first conveyor belt 2.

[0046] In this embodiment, to improve the brushing quality of the flexible circuit board, at least two brushes 4 are used. The brushes 4 can be made of aluminum oxide. The brushes 4 brush the surface of the flexible circuit board at high speed, thereby ensuring the brushing effect of the entire surface of the flexible circuit board. In one embodiment, at least two brushes 4 can be provided, with one brush 4 located on the side of the frame 1 near the board inlet end 21 and the other brush 4 located on the side of the frame 1 near the board outlet end 22.

[0047] like Figure 1As shown, in one embodiment, the grinding device further includes a water spray assembly 9, which includes a second pipe 91, a nozzle 92, and a second mounting bracket. The second mounting bracket is disposed on the side of the frame 1 near the second position 24. The second pipe 91 is disposed on the second mounting bracket, and the nozzle 92 is disposed on the second pipe 91 and communicates with the second pipe 91. The nozzle 92 has a second spray hole 921 for spraying water toward the second position 24 of the first conveyor belt 2.

[0048] In this embodiment, to improve the stability of the connection between the water spray assembly 9 and the frame 1, a second pipe 91 is installed on the frame 1 via a second mounting bracket. To facilitate the water spray assembly 9 in cooling the grinding assembly, the second pipe 91 is connected to an external water source and is located below the second position 24 of the first conveyor belt 2. To increase the spray area of ​​the water spray assembly 9 on the first conveyor belt 2, multiple water spray assemblies 9 are provided, arranged along the extension direction of the first conveyor belt 2, thereby allowing water to be sprayed more evenly onto the first conveyor belt 2 through the second spray holes 921 on the nozzle 92.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
