Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a conductive film covering machine for a circuit board, including a fixed frame 1. One outer wall of the fixed frame 1 is fixedly connected with a machine frame 2. By setting the machine frame 2, the reciprocating lead screw 41 is driven to rotate and the start-stop adjustment is carried out. An adjustment mechanism 4 is arranged on the fixed frame 1. By setting the adjustment mechanism 4, the circuit board is clamped and fixed and the flipping angle is adjusted. An auxiliary mechanism 5 is arranged on the adjustment mechanism 4. By setting the auxiliary mechanism 5, the brush holder 48 is conveniently disassembled, assembled and maintained. The adjustment mechanism 4 includes a U-shaped frame 40. The U-shaped frame 40 is fixedly connected to one outer wall of the fixed frame 1. One inner wall of the U-shaped frame 40 is rotatably connected with a reciprocating lead screw 41 through a bearing. By setting the reciprocating lead screw 41, the movable block 43 is driven to move and adjust. A slideway 42 is opened on one inner wall of the machine frame 2. The reciprocating lead screw 41 is threadedly connected with a movable block 43. The two inner walls of the movable block 43 are hinged with movable rods 44. By setting the movable rods 44 to cooperate with the movable block 43, the two clamps 45 are driven to approach and expand each other, so as to quickly clamp and fix and separate the circuit board. One end of the movable rod 44 away from the movable block 43 is hinged with a clamp 45. A clamping head plate 47 is clamped on the top inner wall of the clamp 45. A brush holder 48 is clamped on the top inner wall of the U-shaped frame 40. By setting the brush holder 48, after each circuit board processing is completed, the clamp 45 is expanded outwards and passes through the brush holder 48 to wipe and clean the clamp 45 to a certain extent.

[0027] Refer to Figures 2 - 4 , one end of the reciprocating lead screw 41 away from the U-shaped frame 40 is fixedly connected to the output end of the machine frame 2 through a coupling. The movable block 43 is slidably connected to the two inner walls of the slideway 42. The clamp 45 is slidably connected to the two inner walls of the U-shaped frame 40. A limiting groove 46 is opened on the top outer wall of the clamp 45. The clamping head plate 47 is slidably connected to the two inner walls of the limiting groove 46. By setting the clamping head plate 47, the circuit board is clamped and fixed. The brush holder 48 is slidably connected to the side outer wall of the clamping head plate 47. One inner wall of the clamp 45 is threadedly connected with a screw 49. By setting the screw 49 to cooperate with the limiting groove 46, the clamping head plate 47 is conveniently installed and separated. One end of the screw 49 penetrates through one inner wall of the clamping head plate 47. One outer wall of the machine frame 2 away from the fixed frame 1 is rotatably connected with a rotating unit 3 through a bearing. The machine frame 2 is fixedly connected to the output end of the rotating unit 3 through a coupling. By setting the rotating unit 3, the machine frame 2 and the overall equipment on the machine frame 2 are driven to carry out flipping adjustment. The above mechanisms are prior art, so no more details are described.

[0028] Refer to Figures 3 - 4, the auxiliary mechanism 5 includes an installation groove 51 which is opened on the inner wall of the top of the U-shaped frame 40. A shifting piece 52 is slidably connected to the inner wall of one side of the brush holder 48. By providing the shifting piece 52, it is not necessary for personnel to use other tools for the convenient assembly and separation of the brush holder 48. A clamping block 53 is fixedly connected to the outer wall of one side of the shifting piece 52. A telescopic spring 54 is fixedly connected to the outer wall of the side of the shifting piece 52 away from the clamping block 53. By providing the telescopic spring 54, a continuous thrust is generated on the shifting piece 52. An indication mark is opened on the outer wall of one side of the shifting piece 52. By providing the indication mark, the operation method is prompted. The brush holder 48 is slidably connected to the inner walls of both sides of the installation groove 51. The clamping block 53 penetrates through the inner wall of one side of the brush holder 48 and extends to the outer wall of one side of the brush holder 48. The clamping block 53 is clamped to the inner wall of one side of the installation groove 51. The end of the telescopic spring 54 away from the shifting piece 52 is fixedly connected to the inner wall of one side of the brush holder 48.

[0029] Working principle: By starting the frame 2 to drive the reciprocating lead screw 41 to rotate, the rotation of the reciprocating lead screw 41 drives the moving block 43 to move. The movement of the moving block 43 drives the two moving rods 44 to move. The movement of the moving rods 44 drives the fixture 45 to move, so that the two fixtures 45 approach each other simultaneously, driving the two chuck plates 47 to quickly clamp and fix and separate the circuit board. At the same time, when the film needs to be flipped, by starting the rotating unit 3 to drive the whole frame 2 to rotate, the clamped circuit board rotates. At the same time, after the circuit board is processed, the fixture 45 expands to both sides to loosen the circuit board. At the same time, when the fixture 45 moves outwards, it contacts the brush holder 48 to wipe and clean the dust and dirt on the surface of the fixture 45 to a certain extent. At the same time, when the brush holder 48 needs to be maintained after long-term use, by pulling the shifting piece 52 to compress the telescopic spring 54, at the same time, the movement of the shifting piece 52 drives the clamping block 53 to move. The movement of the clamping block 53 separates from the inner wall of one side of the installation groove 51. Then, the brush holder 48 is lifted to separate from the installation groove 51 for maintenance.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
