[0030] The embodiment of the present application discloses a cleaning device for an FPC board.

[0031] Reference Figure 1-5 , a cleaning device for an FPC board, comprising a frame 1, on which a feeding roller 2, a traction component 3, a dust sticking component 4, a cleaning component 5, a deviation correction component 6 and a winding roller 7 are arranged, the feeding roller 2 and the winding roller 7 are arranged at both ends of the frame 1, the dust sticking components 4 are arranged on both sides of the cleaning component 5, and the traction component 3 is located below the dust sticking component 4;

[0032] The cleaning assembly 5 includes a rubber roller set 51, an ultrasonic cleaning machine 52, a lifting member 53 and a vacuum adsorption platform 54. The rubber roller set 51 is located on both sides of the ultrasonic cleaning machine 52, and the rubber roller set 51 is rotatably mounted on the frame 1. The lifting member 53 is fixedly arranged on the frame 1, and the lifting member 53 drives the ultrasonic cleaning machine 52 to rise and fall. The vacuum adsorption platform 54 is located below the ultrasonic cleaning machine 52. The FPC board passes between the ultrasonic cleaning machine 52 and the vacuum adsorption platform 54. The lifting member 53 is preferably in the form of a conventional screw rod and a slide rod, or in the form of a cylinder 62.

[0033] In this embodiment, the lifting member 53 is in the form of a conventional screw rod and a sliding rod. The screw rod is threadedly connected to the ultrasonic cleaning machine 52, and the sliding rod is slidingly connected to the ultrasonic cleaning machine 52. The rotation of the screw rod can drive the ultrasonic cleaning machine 52 to adjust the upward and downward displacement. The rubber roller group 51 is composed of two upper and lower rubber rollers.

[0034] During use, the FPC circuit board is unloaded from the turning roller and transmitted over the traction component 3. At the same time, when the FPC circuit board is driven and transmitted by the traction component 3, the front dust-adhesive component 4 adheres dust and impurities to the upper end of the FPC circuit board, and then passes under the ultrasonic cleaning machine 52 in the cleaning component 5 to perform ultrasonic cleaning on the edges of both sides of the FPC board. The dust particles are then adsorbed by the vacuum adsorption platform 54, and then pass through the rear dust-adhesive component 4 for surface cleaning again. Finally, the cleaned FPC board is rolled up on the winding roller 7. Through the setting of the ultrasonic cleaning machine 52 of the cleaning component 5, the edges of both sides of the EPC circuit board can be better cleaned, which relieves the cleaning pressure of the rear dust-adhesive rubber roller 41. At the same time, the vacuum adsorption platform 54 can effectively adsorb and collect the dust particles that fall during cleaning to prevent the dust particles from splashing.

[0035] Reference Figure 3-4 The traction assembly 3 includes a rotating rubber roller 31, a mounting frame 32 and a first motor 33. The mounting frame 32 is fixedly arranged on both ends of the frame 1. Both ends of the rotating rubber roller 31 are rotatably arranged on the mounting frame 32. The first motor 33 is fixedly arranged on the mounting frame 32, and the first motor 33 drives one end of the rotating rubber roller 31 to rotate. When in use, the first motor 33 drives the rotating rubber roller 31 to rotate at the lower end of the mounting frame 32, and drives the FPC to be transmitted forward by the rotating rubber roller 31.

[0036] Reference Figure 3-4 The dust sticking assembly 4 includes a dust sticking rubber roller 41, a dust sticking paper roll 42 and a mounting plate 43. The mounting plate 43 is slidably arranged on the upper end of the mounting frame 32. The dust sticking paper roll 42 is rotatably arranged on the mounting plate 43. Both ends of the dust sticking rubber roller 41 are rotatably arranged on the mounting frame 32, and the dust sticking paper roll 42 abuts against the upper end of the dust sticking rubber roller 41.

[0037] When in use, the FPC board is transported under the sticky rubber roller 41, and at the same time, the sticky rubber roller 41 adheres to the upper end surface of the FPC circuit board to remove dust and impurities, effectively adhering to the impurities on the surface of the FPC circuit board, and then the dust impurities adhered to the surface of the sticky rubber roller 41 are adhered by the sticky paper roll 42 above. In this embodiment, the mounting plate 43 can effectively adjust the moving distance of the mounting plate 43 on the mounting frame 32 through bolts.

[0038] Reference Figure 3-4The mounting frame 32 includes a first mounting bar 321, a second mounting bar 322, a spring 323 and a fixing rod 324. The first mounting bar 321 is fixedly arranged at the bottom of the mounting frame 32. The fixing rod 324 is fixedly arranged on the first mounting bar 321. The second mounting bar 322 is slidably arranged on the fixing rod 324. The spring 323 is arranged between the first mounting bar 321 and the second mounting bar 322, and the spring 323 is sleeved on the fixing rod 324.

[0039] When in use, the sticky rubber roller 41 is rotatably arranged on the second mounting strip 322, and the sticky paper roll 42 abuts against the sticky rubber roller 41, so that the sticky rubber roller 41 has downward pressure, and the arrangement of the spring 323 and the fixing rod 324 can effectively ensure the stability of the downward movement of the second mounting strip 322, and prevent the sticky rubber roller 41 from applying excessive pressure to the FPC circuit board, thereby causing damage to the FPC circuit board, and effectively ensure the stability of the sticky rubber roller 41 when in use, and prevent the sticky rubber roller 41 from deviating, thereby causing the FPC circuit board to deviate during the cleaning process.

[0040] Reference Figure 5 The deflection correction component 6 includes a mobile platform 61, a cylinder 62, a slide rail 63 and a deflection correction sensor 64. The slide rail 63 is fixedly arranged on the frame 1, and the deflection correction sensor 64 is fixedly arranged on the frame 1, and the deflection correction sensor 64 is located on one side of the mobile platform 61. The mobile platform 61 is slidably arranged on the slide rail 63, and the cylinder 62 drives the mobile platform 61 to move; when in use, the deflection correction sensor 64 monitors the position of the FPC circuit board in real time. If it is found that the FPC circuit board is offset during the cleaning process, the deflection correction sensor 64 alarms, and drives the mobile platform 61 to move on the slide rail 63 through the cylinder 62, so that the winding roller 7 is displaced, and the position of the offset FPC circuit board is effectively corrected.

[0041] Reference Figure 1 A tear-off film roller 21 is provided on one side of the unwinding roller 2, and a release film roller 71 is provided on one side of the winding roller 7. Through the setting of the tear-off film roller 21 and the release film roller 71, it can be ensured that in each stage of the FPC manufacturing process, the film, covering layer or substrate can be accurately peeled or torn off, thereby ensuring the quality and performance of the final product.
