Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

Referring to Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the machine tool with touch lamp of the present invention comprises: a machine platform 2 (only partially represented in Fig. 2), a touch lamp 3, a A control circuit 4, and a workbench 5 which is arranged on the machine platform 2 and can accommodate a work object (not shown in the figure).

The touch lamp 3 includes a lamp holder 31 arranged on the machine platform 2 and made of electrically insulating material, and a connecting member arranged on the lamp holder 31 and extending outward from the lamp holder 31 and made of a flexible material. The support portion 32 , a lampshade 33 disposed on the end of the connecting support portion 32 away from the lamp socket 31 , and a light emitting element 34 disposed on the lampshade 33 .

In this embodiment, the lamp holder 31 is made of plastic material, but it can also be other electrically insulating materials, and is not limited thereto.

In this embodiment, the touch lamp 3 is a gooseneck lamp, and the connecting support portion 32 can be flexed by the user to adjust the lighting position of the light emitting element 34 , but it is not limited thereto.

The control circuit 4 includes: an isolation transformer 41 receiving an input power supply Vin to output an internal power supply Vi; An electronic switch 42 for switching between non-conduction, and a touch control module 43 for receiving a touch signal and outputting the control signal.

In this embodiment, the electronic switch 42 is a bidirectional thyristor (Triode ACsemiconductor switch, abbreviated as TRIAC), but it can also be other non-mechanical switches and switching elements that are not affected by falling dust, and the input power Vin can be Direct use of mains power supply is not limited to this.

In general use, the user only needs to touch the connecting support portion 32 or the lampshade 33 to generate the touch signal, and the touch control module 43 outputs the control signal after receiving the touch signal to control the electronic switch 42 to operate. Switch between conduction and non-conduction. When the electronic switch 42 is turned on, the light-emitting element 34 is in a light-emitting state. When the electronic switch 42 is not conducting, the light-emitting element 34 is in a non-light-emitting state. The touch action controls whether the light emitting element 34 emits light or not through the electronic switch 42 .

In this embodiment, the user can generate the touch signal by touching the connection support part 32 or the lampshade 33, but it can also be designed to only touch the connection support part 32 or only by touching the lampshade 33 to generate the touch signal, but not limited thereto.

Through the above description, the advantages of this embodiment can be summarized as follows:

1. By setting the touch lamp 3 and using the electronic switch 42 (triac thyristor) in this embodiment to replace the physical mechanical switch, it is possible to avoid mechanical jamming and contact failure caused by dust accumulation. Short circuit or equipment abnormality, and the electronic switch 42 has a long service life, which can also reduce the impact caused by the instantaneous current when the touch lamp 3 is started (such as light flickering, etc.), and increase the comfort and safety of use.

2. Generally, when the machine 2 leaks electricity without a complete grounding loop, the user will get an electric shock when touching the touch lamp 3, causing hidden worries in public safety. In this embodiment, by setting an electrical insulation The lamp holder 31 made of different materials can insulate the touch-type lamp 3 from the machine 2, so that electric shock accidents can be avoided and safety in use can be improved.

3. When the user holds the connecting support part 32 or the lampshade 33 to adjust the lighting position of the light emitting element 34, the touch signal can be generated by touching the connecting supporting part 32 or the lampshade 33, thereby It is possible to control the light-emitting element 34 to emit light or extinguish while adjusting the lighting position, for example: when adjusting the position where the light-emitting element 34 illuminates the required lighting, control the light-emitting element 34 to emit light at the same time, and when adjusting the light-emitting element 34 back to its original position Controlling the light-emitting element 34 to go out does not need to turn on the mechanical switch before adjusting the lighting position as in the prior art, which is more convenient and time-saving in use.

4. Because the touch lamp 3 is very sensitive to the change of charge, it is easy to cause the malfunction of the touch lamp 3 due to the interference of electrical noise. At present, the AC noise that generally causes the malfunction of the touch lamp 3 in the factory is mainly The source of transient surges is usually lightning strikes, transmission line faults, ground faults of large power equipment, starting or stopping of large motor-driven equipment, instantaneous current of arc starting and breaking in welding operations, and instantaneous current of large circuit breakers when they are opened and closed. By setting the isolation transformer 41, the influence of the transient surge can be isolated.

This is because many transient surges will interfere with the circuit from the ground terminal (or ground wire), and the primary side of the isolation transformer 41 is completely isolated from the secondary side, so it can also isolate the transient state transmitted by the ground terminal. Surge, this is a problem that cannot be solved by a common grounded transformer (such as an autotransformer). In addition, the iron core of the isolation transformer 41 (not shown in the figure, generally uses a silicon steel sheet) will lose high-frequency signals. Therefore, by using an isolation transformer 41. It also has the effect of suppressing high-frequency noise, and can prevent high-frequency AC noise from interfering with circuits.

The method of using the above-mentioned machine tool with a touch lamp includes the following steps:

(A) Place the workpiece on the workbench 5 .

(B) Move the touch lamp 3 so that the position of the light emitting element 34 corresponds to the working object, and touch and turn on the touch lamp 3 at the same time to make the light emitting element 34 emit light.

(C) Touch to turn off the touch lamp 3 so that the light emitting element 34 does not emit light.

In step (C), it is also possible to touch and turn off the touch lamp 3 when moving the touch lamp 3 back to its original position so that the light emitting element 34 does not emit light.

In summary, the present invention can not only avoid equipment abnormalities caused by falling dust, improve safety in use, but also isolate transient surges and reduce malfunctions caused by electrical noise interference, so it can indeed achieve the purpose of the present invention Purpose.
