Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a photoelectric sensor which is easy to install. Background Art

[0002] Photoelectric sensors generally consist of two parts: processing pathways and processing elements. The basic principle is based on the photoelectric effect, which converts the measured changes into changes in light signals, and then further converts non-electrical signals into electrical signals with the help of photoelectric elements. The photoelectric effect refers to the use of light to illuminate an object, which can be regarded as a series of photons with a certain energy bombarding the object. At this time, the photon energy is transferred to the electron, and the entire energy of a photon is absorbed by an electron at one time. After the electron obtains the energy transmitted by the photon, its state will change, thereby causing the object illuminated by light to produce a corresponding electrical effect.

[0003] Existing photoelectric sensors are generally screwed onto the equipment by fastening bolts. This installation method requires opening a pre-hole on the equipment, and then fixing the photoelectric sensor to the equipment by fastening bolts. This installation method is not only cumbersome, but also difficult to adjust the installation position of the photoelectric sensor, and cannot meet the needs of quick installation of the photoelectric sensor.

[0019] The following is a further detailed description through specific implementation methods:

[0020] like Figures 1 to 4 As shown:

[0021] A photoelectric sensor that is easy to install, including a sensor body 5, the sensor body 5 is an existing mature product, which will not be described in detail here. The photoelectric sensor also includes a base 1, a plurality of suction and pressure modules, an adsorption module and a magnetic module. The sensor body 5 is installed on the base 1, and the base 1 is used to support and install the sensor body 5. The adsorption module and the magnetic module are both installed at the bottom of the base 1. The adsorption module and the magnetic module can work together. The photoelectric sensor is installed on the equipment. The magnetic module is located on the outside of the adsorption module, so that the magnetic module and the adsorption module will not interfere with each other, so that the two can work independently. The suction and pressure module is installed on the top of the base 1. The suction and pressure module is used to extract air, so that negative pressure is generated in the adsorption module, so that the adsorption module is firmly adsorbed on the equipment;

[0022] The pressure extraction module includes a mounting support 4, a driving bolt 43 and a piston 44. The mounting support 4 is fixedly mounted on the base 1. A second negative pressure chamber 41 is arranged in the mounting base 1. The piston 44 is adapted to the second negative pressure chamber 41 and the piston 44 is slidably mounted in the second negative pressure chamber 41. The end of the threaded end of the driving bolt 43 is mounted on the top of the piston 44 and the driving bolt 43 is rotatably connected with the piston 44, so that when the driving bolt 43 is screwed and moved upward on the mounting support 4, the piston 44 is driven to move upward together, so that the space of the second negative pressure chamber 41 below the piston 44 becomes larger, thereby making the space in the negative pressure state. The driving bolt 43 is connected to the mounting support 4 by threads, so that the driving bolt 43 can drive the piston 44 to move up and down.

[0023] A first negative pressure chamber 11 is arranged in the base 1, and an air guide hole 12 is opened on the top of the base 1. The first negative pressure chamber 11 is connected to the second negative pressure chamber 41 through the air guide hole 12. The air guide hole 12 balances the air pressure in the first negative pressure chamber 11 and the second negative pressure chamber 41. When the second negative pressure chamber 41 is in a negative pressure state, the first negative pressure chamber 11 can also be in a negative pressure state, thereby making each suction cup 3 of the adsorption module installed on the bottom of the base 1 and connected to the first negative pressure chamber 11 in a negative pressure state, so that the suction cup 3 can be better adsorbed on the equipment.

[0024] The magnetic attraction module is a ring-shaped magnet 2 , which is fixedly mounted on the bottom of the base 1 and surrounds the outer side of the suction cup 3 , so that the magnet 2 and the suction cup 3 do not interfere with each other.

[0025] A countersunk hole 42 is provided on the top of the mounting bracket 4, and a driving bolt 43 is located at the countersunk hole 42 to prevent the driving bolt 43 from protruding too much and scratching other equipment.

[0026] A fixing bracket 7 is installed on the base 1, and the sensor body 5 is mounted on the mounting bracket. An external thread 51 is provided on the outer side of the sensor body 5, and two fastening nuts 6 are screwed on the external thread 51 of the sensor body 5, so that the two fastening nuts 6 are clamped on both sides of the fixing bracket 7, thereby fixing the sensor body 5 on the fixing bracket 7.

[0027] The specific implementation process is as follows:

[0028] When using the photoelectric sensor which is easy to install, firstly, the sensor body 5 is mounted on the fixed bracket 7 on the base 1, and then the two fastening nuts 6 are sleeved on the external thread 51 of the sensor body 5 so that the two fastening nuts 6 are clamped on both sides of the fixed bracket 7, thereby fixing the sensor body 5 on the fixed bracket 7, and then the photoelectric sensor can be installed on the device. When installing the photoelectric sensor, the bottom of the base 1 is pressed down to the device, and the magnet 2 can be adsorbed on the device. At the same time, the suction cup 3 is pressed down to discharge part of the air inside it, so that the suction cup 3 is adsorbed on the surface of the device, and then the driving bolt 43 can be screwed to make the driving bolt 43 move up on the mounting support 4, driving the piston 44 to move together, so that the space of the second negative pressure chamber 41 under the piston 44 becomes larger, and the air in the suction cup 3 and the first negative pressure chamber 11 is extracted, thereby forming a negative pressure at the second negative pressure chamber 41, the first negative pressure chamber 11 and the suction cup 3, so that the adsorption force of the suction cup 3 is stronger, thereby making the photoelectric sensor more firmly fixed on the device.

[0029] This easy-to-install photoelectric sensor can initially install the sensor body 5 on the equipment through the magnetic suction module, and extract the air in each suction cup 3 through the suction and pressure module to make the suction cup 3 a negative pressure state, so that the suction cup 3 can be firmly adsorbed on the equipment. This photoelectric sensor is quick and convenient to install, and its installation position is easy to adjust, which can meet the installation requirements of the sensor body 5.
