Description

Technical Field

[0001] The present application relates to the technical field of switch production, and in particular to a reverse screw loosening mechanism. Background Art

[0002] Switch production is a device used to control the switch of electric lights or other electrical equipment. It is usually installed on the wall of the room, control equipment, etc., so that people can easily control the switch status of lights or electrical equipment when entering or leaving the room. The switch production process requires the production and processing of various components of the switch, and finally assembling them. In the processing process, the components need to be installed on the carrier mechanism and fixed with screws so that the components cannot fall off the carrier mechanism to complete the processing of the components.

[0003] After the above-mentioned components are processed, the components need to be transported by the carrier mechanism to the bottom of the mechanism for reverse loosening the screws, so as to change the degree of clamping of the components by the carrier mechanism, so as to facilitate the removal of the components from the carrier mechanism in the next process. Firstly, in the process of reverse loosening the screws, the device used is not equipped with any sensors, so that the screws of the carrier mechanism will be reverse loosened regardless of whether the components are installed on the carrier mechanism, thereby wasting unnecessary energy and time. Secondly, the carrier mechanism sets the transportation distance and positioning status through the control system. When the relative position of the carrier mechanism and the device used changes slightly, it is impossible for the drill bit to be accurately engaged with the screw, thus affecting the use effect.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Reference Figure 1-3 A reverse screw loosening mechanism comprises a transfer mechanism 1, a plurality of evenly arranged carrier mechanisms 2 are installed around the upper surface of the transfer mechanism 1, a support mechanism 3 is arranged on one side of the transfer mechanism 1, a loosening mechanism 4 is installed on the upper end of the support mechanism 3, a guide cylinder 5 passes through the lower end of the loosening mechanism 4, and the guide cylinder 5 is installed at the front end of the support mechanism 3, a photoelectric sensor 6 is installed on the side of the support mechanism 3, and a laser emitter 7 is installed under the front end plate of the support mechanism 3.

[0027] Reference Figure 1-3The transfer mechanism 1 includes a first motor 101, a turntable 102 is installed at the output end of the first motor 101, and a carrier mechanism 2 is installed at the edge of the upper surface of the turntable 102. The carrier mechanism 2 includes a mounting block 201, a clamping opening 202 is opened in the middle of one side of the mounting block 201, a tightening screw 203 is threadedly connected to the end of the upper surface of the mounting block 201 away from the first motor 101, and a laser sensor 204 is installed in the middle of the side of the mounting block 201 away from the center of the turntable 102. When in use, the first motor 101 drives the turntable 102 to rotate to realize the transportation of the carrier mechanism 2, and the tightening screw 203 on the carrier mechanism 2 is responsible for fixing the components to be processed inside the clamping opening 202, that is, to realize the transportation of the components to be processed.

[0028] Reference Figure 1-3 The support mechanism 3 includes a support rod 301, which is located at one side of the transfer mechanism 1. A top plate 303 is fixedly connected to the support rod 301. The loosening mechanism 4 is installed below the top plate 303. A bracket 302 is fixedly connected to the upper end of the support rod 301 and located below the top plate 303. A guide cylinder 5 is installed on the bracket 302 and located below the loosening mechanism 4. The top plate 303 is responsible for supporting the loosening mechanism 4 and maintaining the relative position between the loosening mechanism 4 and the carrier mechanism 2. The bracket 302 corrects the output direction of the loosening mechanism 4 through the guide cylinder 5 to ensure the implementation effect.

[0029] Reference Figure 1-3 The loosening mechanism 4 includes an electric telescopic rod 401, the upper end of which is connected to the top plate 303, and a second motor 402 is installed below the electric telescopic rod 401. A drill bit 403 is fixedly connected to the output end of the second motor 402, and the drill bit 403 is set through the guide cylinder 5. When the carrier mechanism 2 is transported to the bottom of the loosening mechanism 4, the electric telescopic rod 401 extends to push the second motor 402 to move downward along the guide cylinder 5, so that the drill bit 403 below the second motor 402 is connected to the tightening screw 203, and then the second motor 402 drives the drill bit 403 and the tightening screw 203 to rotate, thereby achieving the effect of loosening the tightening screw 203.

[0030] Reference Figure 1-3 , the laser emitter 7 is installed below the bracket 302, and the laser emitter 7 is located at the upper end of the rotation path of the laser sensor 204. When the transfer mechanism 1 transports the carrier mechanism 2 to the bottom of the loosening mechanism 4, the laser emitter 7 and the laser sensor 204 are located on the same vertical line. The laser sensor 204 receives the signal from the laser emitter 7 and prompts the transfer mechanism 1 to stop transporting the carrier mechanism 2, thereby achieving the effect of automatically aligning the carrier mechanism 2 and the loosening mechanism 4 according to its actual relative position.

[0031] Reference Figure 1-3The photoelectric sensor 6 is installed on one side of the bracket 302, and the photoelectric sensor 6 is located at an obliquely upper position of the rotation path of the carrier mechanism 2. After the transport carrier and the loosening mechanism 4 are automatically aligned, the photoelectric sensor 6 is responsible for detecting whether there is a component to be processed on the carrier mechanism 2. If there is, the loosening mechanism 4 is prompted to loosen the component. If not, the loosening mechanism 4 is stopped and the transport operation is ignored, thereby avoiding the waste of time, energy and other resources.

[0032] Working principle: When in use, the first motor 101 drives the turntable 102 to rotate to realize the transportation of the carrier mechanism 2. The tightening screw 203 on the carrier mechanism 2 is responsible for fixing the component to be processed inside the clamp 202, that is, realizing the transportation of the component to be processed. The top plate 303 is responsible for supporting the loosening mechanism 4 and maintaining the relative position of the loosening mechanism 4 and the carrier mechanism 2. The bracket 302 corrects the output direction of the loosening mechanism 4 through the guide cylinder 5 to ensure the implementation effect. When the carrier mechanism 2 is transported to the bottom of the loosening mechanism 4, the electric telescopic rod 401 extends to push the second motor 402 to move downward along the guide cylinder 5, so that the drill bit 403 under the second motor 402 is connected to the tightening screw 203, and then the second motor 402 drives the drill bit 403 and the tightening screw 203 to rotate, thereby achieving the effect of loosening the tightening screw 203;

[0033] When the transfer mechanism 1 transports the carrier mechanism 2 to the bottom of the loosening mechanism 4, the laser emitter 7 and the laser sensor 204 are located on the same vertical line. The laser sensor 204 receives the signal from the laser emitter 7 and prompts the transfer mechanism 1 to stop transporting the carrier mechanism 2, thereby achieving the effect of the device automatically aligning the carrier mechanism 2 and the loosening mechanism 4 according to its actual relative position. After the transport carrier and the loosening mechanism 4 are automatically aligned, the photoelectric sensor 6 is responsible for detecting whether there is a component to be processed on the carrier mechanism 2. If so, the loosening mechanism 4 is prompted to perform the loosening operation. If not, the loosening mechanism 4 is stopped and the transport operation is ignored, thereby avoiding the waste of time, energy and other resources.

[0034] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
