[0029] like Figure 1-Figure 3 As shown, an intelligent and highly conductive anti-static screwdriver device is provided, the device comprising: a screwdriver body 1, the screwdriver body 1 comprising a housing 11, a motor 12 and an output shaft 13, the motor 12 is installed in the housing 11, and the output shaft 13 is drivingly connected to the output end of the motor 12;

[0030] The conductive member 2 is sleeved on the output shaft 13 , the inner wall of the conductive member 2 abuts against the output shaft 13 , and the outer wall of the conductive member 2 abuts against the housing 11 .

[0031] The housing 11 is provided with a bearing seat 111, and a first bearing 112 and a second bearing 113 are installed in the bearing seat 111. The first bearing 112 and the second bearing 113 are arranged at an interval, and a mounting groove 114 is formed between the first bearing 112 and the second bearing 113. The output shaft 13 is installed in the first bearing 112 and the second bearing 113, and the conductive member 2 is located in the mounting groove 114, and the outer wall of the conductive member 2 abuts against the bearing seat 111.

[0032] The conductive member 2 is a beryllium copper reed, which is sleeved on the output shaft 13 and located in the mounting groove 114 .

[0033] The beryllium copper reed is provided with an opening. The beryllium copper reed comprises a connecting portion 21, two ends of the connecting portion 21 are provided with a bending portion 22, one end of the bending portion 22 away from the connecting portion 21 forms an abutting portion 23 inwardly, the connecting portion 21 and the bending portion 22 abut against the output shaft 13, and the bending portion 22 abuts against the bearing seat 111.

[0034] The inner side surfaces of the connecting portion 21 and the abutting portion 23 are both planes, and the width of the connecting portion 21 is equal to the width of the abutting portion 23 .

[0035] The outer side surface of the bending portion 22 is an arc surface. The width of the bending portion 22 is greater than the widths of the connecting portion 21 and the abutting portion 23 .

[0036] Specifically, in an embodiment of the present invention, with the popularization of automated equipment and the demand for intelligent assembly line assembly, the application of smart screwdrivers tends to be widespread, and the requirements for intelligence, automation, high precision, and anti-static for the production line of electronic equipment are getting higher and higher. Static electricity is generated by friction during the rotation of the smart screwdriver. Most of the existing smart screwdrivers do not have the function of eliminating static electricity. The generated static electricity is mostly directed to the product through metal screws, which will cause the risk of damaging the product workpiece. In view of this, the present invention provides an intelligent and highly conductive anti-static screwdriver device to eliminate the static electricity generated during the rotation of the smart screwdriver to avoid damage to the workpiece.

[0037] like Figure 1 and 2 As shown, the screwdriver includes a screwdriver body 1 and a conductive member 2, wherein the screwdriver body 1 includes a shell 11, a motor 12 and an output shaft 13, wherein the motor 12 is installed in the shell 11, and the output shaft 13 is transmission-connected to the output end of the motor 12; the conductive member 2 is sleeved on the output shaft 13, the inner wall of the conductive member 2 abuts against the output shaft 13, and the outer wall of the conductive member 2 abuts against the shell 11.

[0038] In the present screwdriver, it can be understood that the conductive member 2 is made of metal and has good conductivity. Since the conductive member 2 is sleeved on the output shaft 13, the inner wall of the conductive member 2 abuts against the output shaft 13, and the outer wall of the conductive member 2 abuts against the housing 11, that is, the housing 11, the motor 12 and the conductive member 2 form a conductive loop. When the screwdriver is working, the generated static electricity is eliminated through the conductive loop, effectively preventing the static electricity from affecting the workpiece and avoiding the static electricity from damaging the workpiece.

[0039] like Figure 1 and 2As shown, in this embodiment, a bearing seat 111 is provided on the housing 11, and a first bearing 112 and a second bearing 113 are installed in the bearing seat 111. The first bearing 112 and the second bearing 113 are arranged at intervals, and a mounting groove 114 is formed between the first bearing 112 and the second bearing 113. The output shaft 13 is installed in the first bearing 112 and the second bearing 113, and the conductive member 2 is located in the mounting groove 114, and the outer wall of the conductive member 2 abuts against the bearing seat 111. In this structure, the output shaft 13 is installed in the first bearing 112 and the second bearing 113. As an embodiment, a spline is installed in the first bearing 112 and the second bearing 113, and the transmission connection between the output end of the motor 12 and the output shaft 13 is realized by the spline; the mounting groove 114 is formed between the first bearing 112 and the second bearing 113 to facilitate the installation of the conductive member 2; the outer wall of the conductive member 2 abuts against the bearing seat 111 to form a conductive loop, and the generated static electricity is eliminated through the conductive loop.

[0040] like Figure 1 and 2 As shown, in this embodiment, the conductive member 2 is a beryllium copper reed, which is sleeved on the output shaft 13 and located in the mounting groove 114. In this structure, the conductive member 2 is a beryllium copper reed. On the one hand, the beryllium copper reed has good conductivity, which is conducive to eliminating the generated static electricity through the conductive loop. On the other hand, the beryllium copper reed has elasticity, which can ensure that the inner wall of the beryllium copper reed abuts against the output shaft 13, and the outer wall of the beryllium copper reed abuts against the bearing seat 111, ensuring the formation of a conductive loop.

[0041] like Figure 1-3 As shown, in this embodiment, the beryllium copper reed is set in an open position. In this structure, the beryllium copper reed is set in an open position, which is convenient for the installation of the beryllium copper reed, not only reducing the difficulty of processing and assembly, but also improving the overall elasticity of the beryllium copper reed, and achieving better conductivity and low friction when the output shaft 13 has a large runout.

[0042] like Figure 3 As shown, in this embodiment, the beryllium copper reed includes a connecting portion 21, and a bending portion 22 is provided at both ends of the connecting portion 21. The end of the bending portion 22 away from the connecting portion 21 forms an abutting portion 23 inwardly, and the connecting portion 21 and the bending portion 22 abut against the output shaft 13, and the bending portion 22 abuts against the bearing seat 111. In this structure, a bending portion 22 is provided at both ends of the connecting portion 21, and the end of the bending portion 22 away from the connecting portion 21 forms an abutting portion 23 inwardly, and the connecting portion 21 and the bending portion 22 abut against the output shaft 13, that is, the beryllium copper reed has three faces abutting against the output shaft 13, achieving multi-point contact, ensuring the formation of a conductive circuit, and facilitating the elimination of static electricity.

[0043] like Figure 3As shown, in this embodiment, the inner side surfaces of the connecting portion 21 and the abutting portion 23 are both planes, and the width of the connecting portion 21 is equal to the width of the abutting portion 23. The outer side surface of the bending portion 22 is an arc surface; the width of the bending portion 22 is greater than the width of the connecting portion 21 and the abutting portion 23. In this structure, the outer side surface of the bending portion 22 is an arc surface, and the width of the bending portion 22 is greater than the width of the connecting portion 21 and the abutting portion 23, ensuring that when the bending portion 22 of the beryllium copper spring contacts the outer ring of the bearing, the connecting portion 21 and the abutting portion 23 do not contact the inner ring of the bearing.

[0044] That is to say, in the embodiment of the present invention, the device is provided with an output shaft, a bearing, a bearing seat, a motor, and a beryllium copper reed; wherein the output shaft is connected to the motor by a spline, there are two bearings between the output shaft and the bearing seat, the bearing is installed in the bearing seat by an interference fit, the beryllium copper reed is directly fitted on the output shaft and installed between the two bearings, wherein the beryllium copper yellow sheet is designed as follows Figure 3 As shown, the outer ring has two arc surfaces that contact the inner hole of the bearing seat, and the inner ring has three planes that achieve multi-point contact with the output shaft body. The axial width of the outer ring arc surface is wider than the inner ring plane, ensuring that when the beryllium copper spring contacts the outer ring of the bearing, the inner ring does not contact the inner ring of the bearing. The overall open design not only reduces the difficulty of processing and assembly, but also improves the overall elasticity, and can achieve better conductivity and low friction when the output shaft has large vibration.

[0045] In other words, the high elasticity of the beryllium copper reed conducts the electricity of the smart screwdriver motor to the housing. The multi-point contact design ensures effective contact and reduces friction on the rotating shaft. The special installation position does not require additional grounding space.

[0046] In general, the present invention provides an intelligent and highly conductive anti-static screwdriver device, that is, the device includes: a screwdriver body, the screwdriver body includes a shell, a motor and an output shaft, the motor is installed in the shell, and the output shaft is transmission-connected to the output end of the motor; a conductive member, the conductive member is sleeved on the output shaft, the inner wall of the conductive member is abutted against the output shaft, and the outer wall of the conductive member is abutted against the shell; the design of line contact can effectively ensure conductivity, and batch manufacturing can be completed by only a stamping molding process, so that the processing technology is simple and efficient, and the device has a highly elastic opening design, which is simple and fast to install and has low maintenance costs; no additional space is required, and it is integrated in the intelligent screwdriver body.

[0047] That is to say, through the scheme of the present invention, the conductive part is sleeved on the output shaft, the inner wall of the conductive part abuts against the output shaft, and the outer wall of the conductive part abuts against the shell, that is, the shell, the motor and the conductive part form a conductive circuit. When the screwdriver is working, the static electricity generated is eliminated through the conductive circuit, effectively preventing the static electricity from affecting the workpiece and avoiding static electricity from damaging the workpiece.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention.
