[0002] Color mark sensors play a crucial role in industrial automation and many related fields. They are mainly used to detect various labels. Even if there are slight differences in the background color, they can quickly and accurately complete the detection task. Their working principle is not to directly measure the color, but to detect the color mark by comparing the difference between the reflection or absorption of the light beam and the surrounding material.

[0003] The existing long-distance color mark sensor mounting structure is not stable enough. At the same time, the heat generated by some internal electrical components during operation cannot be dissipated in time, which reduces the heat dissipation effect of the long-distance color mark sensor. Therefore, the heat accumulated inside damages the electrical components, accelerates the aging process, and thus shortens the service life of the long-distance color mark sensor.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] This utility model provides, for example Figures 1-5 The long-range color mark sensor shown includes a housing 1 and a base 2. A positioning seat 3 is fixedly connected to the surface of the base 2. A retaining seat 4 is fixedly connected to the bottom of the inner cavity of the housing 1. The base 2 is snapped into the bottom of the housing 1 by the positioning seat 3. The positioning seat 3 is snapped into the inner side wall of the retaining seat 4. A fastening component 5 is provided between the base 2 and the retaining seat 4 to cooperate with the housing 1. The snapping cooperation between the positioning seat 3 and the retaining seat 4 can provide a limiting effect on the connection between the base 2 and the housing 1. Subsequently, the cooperation of the fastening component 5 enhances the stability of the overall structural connection, making it difficult for the housing 1 and the base 2 to separate.

[0024] A heat dissipation assembly 6 is installed on the positioning base 3. A circuit board 7 is provided on the surface of the heat dissipation assembly 6. An electrical component 8 for use by the long-distance color mark sensor is provided on the surface of the circuit board 7.

An optical fiber 11 connected to the electrical component 8 is inserted into the inner cavity of the protective sleeve 10. A display 12 for use by the long-distance color mark sensor is installed on the top of the housing 1. Light is emitted by the LED light source and illuminated on the detection target. The detection range of the long-distance color mark sensor is between 30 and 500 mm. There is a difference in the amount of light reflected or absorbed by the color mark and the surrounding materials. The reflected light is transmitted through the optical fiber 11 to the part connected to the electrical component 8. The electrical component 8 processes and analyzes the light signal to determine whether a color mark is detected, and displays the detection result intuitively through the display 12 installed on the top of the housing 1, which is convenient for the operator to observe and record. Thus, the operation of the long-distance color mark sensor is completed. In addition, the heat dissipation assembly 6 can dissipate the heat generated by the long-distance color mark sensor during use.

[0025] Note: For long-distance color mark sensors, the recommended model is DLBC-500N when NPN output is selected, and DLBC-500P when PNP output is selected.

[0026] The fastening assembly 5 includes a limiting hole 51 and a positioning hole 52. The limiting hole 51 is formed on the surface of the outer shell 1, and the positioning hole 52 is formed on the positioning seat 3 and the retaining seat 4. The limiting hole 51 and the positioning hole 52 are positioned correspondingly. The inner cavities of the limiting hole 51 and the positioning hole 52 are threadedly connected to a positioning bolt 53. The outer end of the positioning bolt 53 is engaged in the limiting hole 51. A sealing sleeve 54 is engaged in the limiting hole 51. The inner wall of the sealing sleeve 54 is fitted onto the outer end of the positioning bolt 53. By threading the positioning bolt 53 into the limiting hole 51 and the positioning hole 52, the outer shell 1 and the base 2 are firmly connected. The sealing sleeve 54 engaged in the limiting hole 51 is fitted onto the outer end of the positioning bolt 53, which not only provides a sealing function but also further prevents the positioning bolt 53 from loosening, thereby ensuring the stability of the entire connection structure.

[0027] The heat dissipation assembly 6 includes a heat sink 61, on which two symmetrical sides are mounted on a positioning seat 3 via multiple positioning components 62. Heat dissipation holes 63 are symmetrically positioned on the surface of the heat sink 61. A cooling fan 64 is mounted on the lower surface of the heat sink 61 at the location of the heat dissipation holes 63. A heat dissipation channel 65 is formed between the positioning seat 3 and the heat sink 61. Heat dissipation vents 66, which cooperate with the heat dissipation channel, are correspondingly positioned at both ends of the outer shell 1, the card holder 4, and the positioning seat 3. The positioning component 62 includes a insertion hole 621 and a positioning pin 622. The insertion hole 621 is located on both sides of the heat sink 61 and the mounting seat, and the positioning pin 622 is inserted into the heat sink. The heat sink 61 is installed on the positioning base 3 via multiple positioning components 62, which are connected to the socket 621. The positioning components 62 consist of the socket 621 and the positioning pin 622. The socket 621 is respectively opened on both sides of the heat sink 61 and the mounting base. The positioning pin 622 is inserted into the socket 621, which facilitates installation and ensures the accuracy of the installation position of the heat sink 61. The heat sink 61 has symmetrical heat dissipation holes 63 on its surface. The cooling fan 64 is installed on the lower surface at the position of the heat dissipation hole 63. When the cooling fan 64 is working, it exhausts the hot air around the heat sink 61 through the heat dissipation hole 63, accelerates air circulation, and dissipates the heat from the surface of the circuit board 7.

[0028] The distance between any two adjacent sockets 621 is equal. The edges of the outer casing 1 and the base 2 are rounded. By rounding the originally sharp corners, the sharpness of the corners is reduced, thus lowering the risk of accidental injury to the operator.

[0029] In practical use, the snap-fit ​​between the positioning seat 3 and the card holder 4 firstly provides a limiting effect on the connection between the base 2 and the outer shell 1. The outer shell 1 and the base 2 are then firmly connected by the positioning bolt 53 threaded into the limiting hole 51 and the positioning hole 52. The sealing sleeve 54, snapped into the limiting hole 51, is fitted onto the outer end of the positioning bolt 53, not only providing a seal but also further preventing the positioning bolt 53 from loosening, thus ensuring the stability of the entire connection structure and making it difficult for the outer shell 1 and the base 2 to separate. When the long-distance color mark sensor is working, the added heat dissipation component 6 can dissipate heat from the internal circuit board 7 and electrical components 8. The positioning component 62 consists of a socket 621 and a positioning pin 622. The socket 621 is respectively opened on both sides of the heat sink 61 and the fixing base. The positioning pin 622 is inserted into the socket 621, which facilitates installation and ensures the accuracy of the installation position of the heat sink 61. The heat sink 61 has symmetrical heat dissipation holes 63 on its surface. A cooling fan 64 is installed on the lower surface at the position of the heat dissipation hole 63. When the cooling fan 64 is working, it exhausts the hot air around the heat sink 61 through the heat dissipation hole 63, accelerates air circulation, and dissipates heat from the surface of the circuit board 7. This slows down the aging of the internal electrical components 8 of the long-distance color mark sensor, thereby extending the service life of the long-distance color mark sensor.
