Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 6 The device shown is an automatic screw-tightening device for a light bulb threaded end, comprising a light bulb tightening device 1, which includes a light bulb 101. One end of the light bulb 101 is provided with a threaded connecting plate 102, which is rotatably connected to the light bulb 101. A button 103 is provided on the circumferential surface of the threaded connecting plate 102 near the light bulb 101. A motor A104 is fixedly connected to the inner surface of the threaded connecting plate 102. A connecting rod 105 is fixedly connected to the fixed output shaft of the motor A104. A rotating rod 106 is fixedly connected to the circumferential surface of the connecting rod 105 away from the motor A104. The device also includes a cleaning device 2 for cleaning the surface of the light bulb 101 and an auxiliary device 3 for improving cleaning efficiency. The cleaning device 2 includes a cylindrical plate 203, and a rotating plate 301 is fixedly connected to the circumferential surface of the cylindrical plate 203.

[0026] The cleaning device 2 includes an annular plate 201. A motor B202 is fixedly connected to the inner surface of the annular plate 201. A cylindrical plate 203 is fixedly connected to the fixed output shaft of the motor B202. A semi-annular plate 204 passes through the circumferential surface of the cylindrical plate 203 away from the motor B202 and is rotatably connected to the cylindrical plate 203. A rotating column 205 passes through the end of the semi-annular plate 204 away from the cylindrical plate 203 and is rotatably connected to the semi-annular plate 204. A fixing plate 206 is fixedly connected to one end of the rotating column 205. A circular column 207 passes through the circumference of the 204 and is slidably connected to the semi-circular plate 204. A spring 208 is fitted on the circumference of the circular column 207 away from the bulb 101 and is fixedly connected to the circular column 207. A support plate 209 is hinged to the end of the circular column 207 near the bulb 101. A cleaning plate 210 is fixedly connected to the end of the support plate 209 away from the circular column 207. In the above design, the cylindrical plate 203 is driven to rotate by the motor B202 through the output shaft, providing a power source for the cleaning device 2.

[0027] A circular plate 201 is disposed on the circumferential surface of the bulb 101. One end of a fixing plate 206 is fixedly connected to the inner surface of the circular plate 201. There are several cleaning plates 210, which are evenly distributed along the circumferential surface of the semi-circular plate 204. The circumferential surface of the semi-circular plate 204 near the bulb 101 is disposed on the circumferential surface of the bulb 101, and the side of the cleaning plate 210 away from the support plate 209 is disposed on the surface of the bulb 101. In the above design, the even distribution of the cleaning plates 210 can achieve all-round synchronous cleaning and coverage of the surface of the bulb 101.

[0028] The threaded connecting plate 102 has a cavity inside. The bottom of the motor A104 is fixedly connected to the surface of the cavity inside the threaded connecting plate 102. The end of the rotating rod 106 away from the connecting rod 105 is fixedly connected to the inner surface of the threaded connecting plate 102. In the above design, by providing stable support for the motor A104, it is ensured that its output torque is effectively transmitted to the connecting rod 105 to perform the tightening operation.

[0029] Specifically: First, the cylindrical plate 203, fixedly connected to its fixed output shaft, is driven to rotate by the motor B202. This rotation causes the semi-annular plate 204, which is rotatably connected to it, to oscillate back and forth around the circumference of the bulb 101. Since the semi-annular plate 204 is rotatably connected to the fixed plate 206, which is fixedly connected inside the annular plate 201, through the rotating column 205, several circular columns 207 evenly distributed on the circumference of the semi-annular plate 204 slide axially under the preload of the spring 208, thereby pushing the cleaning end connected to the support plate 209. The plate 210 is always pressed against the surface of the bulb 101. As the semi-ring plate 204 moves in conjunction with the cleaning plate 204, the cleaning plate 210 forms a continuous and uniform wiping action on the surface of the bulb 101. Secondly, the ring plate 201 is fixedly fitted onto the circumference of the bulb 101 to provide support, ensuring the stability and thoroughness of the cleaning operation. This solves the problem that dust accumulated on the surface of the bulb 101 due to long-term operation will hinder light transmission, form diffuse reflection, and cause a significant decrease in lighting brightness and efficiency. It may also affect heat dissipation and indirectly shorten the life of the bulb 101.

[0030] Example 2

[0031] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0032] In a preferred embodiment, the auxiliary device 3 further includes a rotating wheel 302. A connecting plate 303 is provided on one side of the rotating wheel 302. A spring telescopic rod 304 is fixedly connected to the side of the connecting plate 303 away from the rotating wheel 302. A baffle 305 is fixedly connected to the end of the spring telescopic rod 304 away from the connecting plate 303. A pressure plate 306 is fixedly connected to the side of the connecting plate 303 near the rotating wheel 302. An airbag 307 is provided on the side of the pressure plate 306 away from the rotating wheel 302. A connecting pipe 308 is fixedly connected to the top of the airbag 307. A spray pipe 309 is fixedly connected to the end of the connecting pipe 308 away from the airbag 307.

[0033] In a preferred embodiment, a rotating wheel 302 is hinged to one end of the rotating plate 301 away from the cylindrical plate 203. There are four rotating plates 301, which are evenly distributed along the circumference of the cylindrical plate 203. The above design ensures that the rotating plate 301 can drive the rotating wheel 302 smoothly and continuously, so as to achieve periodic and uniform compression of the airbag 307.

[0034] In a preferred embodiment, the airbag 307 is fixedly connected to the surface of the baffle 305 on the circumferential surface away from the pressure plate 306. A plurality of nozzles are provided on the circumferential surface of the spray pipe 309, and the end of the nozzle away from the spray pipe 309 is located at the connection between the cleaning plate 210 and the bulb 101. The above design sprays cleaning gas to the contact area between the cleaning plate 210 and the bulb 101, improving cleaning efficiency and reducing dust.

[0035] The working process of this utility model is as follows: First, the cylindrical plate 203 rotates to drive four evenly distributed rotating plates 301 to make circular motion, thereby causing the rotating wheel 302 hinged at the far end of the rotating plate 301 to generate periodic displacement. When the rotating wheel 302 contacts and squeezes the connecting plate 303, it pushes the pressure plate 306 fixedly connected to the connecting plate 303 to move towards the airbag 307, thereby realizing the compression operation of the airbag 307. At this time, the spring telescopic rod 304 is compressed and stores energy under pressure, thereby increasing the internal pressure of the airbag 307 after compression, and pressing the cleaning gas stored inside into the spray pipe 309 through the connecting pipe 308 fixedly connected at the top, and finally spraying it precisely atomized by several nozzles set on the circumferential surface of the spray pipe 309 to the contact area between the cleaning plate 210 and the surface of the bulb 101. When the rotating wheel 302 disengages from the connecting plate 303, the spring telescopic rod 304 releases its stored energy to push the connecting plate 303 to reset the pressure plate 306. This allows the airbag 307 to return to its original shape and form a negative pressure, preparing for the next compression spray. This softens stubborn stains, effectively prevents dust from being generated during cleaning, and reduces the frictional resistance between the cleaning plate 210 and the surface of the bulb 101, significantly improving cleaning efficiency and effectiveness.

[0036] The above describes the working principle of this automatic screw-tightening device for light bulb threads.
