[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] This embodiment provides a printed circuit board static removal device. Figures 1 to 3 As shown, it includes: a processing platform 1, a static electricity removal mechanism 2, a transmission mechanism 3 and a pushing mechanism 4; the processing platform 1 is divided into a transmission area 5, a pushing area 6 and a placement area 7; the transmission area 5, the pushing area 6 and the placement area 7 are arranged in the transmission direction in sequence; the transmission mechanism 3 is arranged in the transmission area 5, for driving the movement of the printed circuit board; the static electricity removal mechanism 2 is arranged in the pushing area 6, for exporting the static electricity generated in the process of printing the circuit board; the pushing mechanism 4 is arranged in the pushing area 6, for pushing the printed circuit board in the pushing area 6 to the placement area 7.

[0022] The transmission mechanism 3 includes a transmission roller 8, a guide roller 9 and a servo motor 10. The transmission roller 8 is rotatably arranged on the processing platform 1. The output end of the servo motor 10 is connected to any transmission roller 8. The guide roller 9 is arranged on the top of the transmission roller 8. The gap between the guide roller 9 and the transmission roller 8 is passed by the printed circuit board. After the servo motor 10 is started, the output shaft of the servo motor 10 drives the transmission roller 8 to transmit. Several transmission rollers 8 are driven by the transmission belt. The guide roller 9 located on the top of the transmission roller 8 plays a guiding and limiting role in the transmission process of the printed circuit board.

[0023] The static electricity removal mechanism 2 includes a copper rod 11 and a static electricity conductive copper wire 12; the copper rod 11 is installed on the outdoor ground, one end of the static electricity conductive copper wire 12 contacts the printed circuit board in the material pushing area 6, and the other end of the static electricity conductive copper wire 12 is installed on the processing platform 1 through a tightening member, and the static electricity conductive copper wire 12 is connected to the copper rod 11. When the printed circuit board is transmitted to the material pushing area 6 along the transmission area 5, the static electricity conductive copper wire 12 contacts the upper end surface of the printed circuit board, so that the static electricity on the printed circuit board is guided by the static electricity conductive copper wire 12 to the copper rod 11 to the ground.

[0024] The pushing mechanism 4 includes a cylinder 13 and a pushing plate 14. The cylinder 13 is arranged in the pushing area 6, and the pushing plate 14 is arranged at the output end of the cylinder 13. When the printed circuit board is transferred to the processing platform 1 in the pushing area 6, the cylinder 13 pushes the printed circuit board from the pushing area 6 to the placement area 7, so as to facilitate manual picking. After the cylinder 13 pushes, it continues to retreat and reset, and the solid line pushes the material again. The reciprocating cycle continuously feeds the printed circuit board;

[0025] A plurality of welding rods 15 are arranged in a linear array on the processing platform 1, and a certain height difference is formed between the plurality of welding rods 15 and the processing platform 1. The welding rods are raised to create a spacing height between the processing platform 1, so as to facilitate manual picking of the manufactured printed circuit board.

[0026] A fan 16 is also installed on the transmission area 5 for washing the surface of the printed circuit board. The fan 16 is placed toward the transmission position of the printed circuit board, and the fan 16 blows away dust and impurities on the printed circuit board during the transmission process of the printed circuit board.

[0027] The printed circuit board is transmitted on the processing platform 1 by the transmission mechanism 3, and the transmission area 5 is transmitted to the pushing area 6. The static electricity removal mechanism 2 on the pushing area 6 contacts the end face of the printed circuit board, so that the static electricity attached to the production and manufacturing of the printed circuit board is conducted to the copper rod 11 by the static electricity conducting copper wire 12, and finally to the ground, thereby reducing the impact of static electricity on the operation of electrical components and damage during the use of the printed circuit board.

[0028] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
