Description

Technical Field

[0001] The utility model relates to the field of visual detection systems, in particular to a visual detection light source which is convenient for heat dissipation. Background Art

[0002] In industrial production, the requirements for product quality and production efficiency are increasing day by day, and product inspection and quality control need to be carried out quickly and accurately. Visual inspection systems can replace traditional manual inspections and improve inspection accuracy and speed.

[0003] At present, LED light source is the most common and widely used light source in visual inspection system. LED light source has the advantages of low energy consumption, long life, fast start-up, adjustable color temperature, etc. In visual inspection system, LED light source can provide stable and uniform illumination, which is suitable for most industrial and machine vision applications. Although most visual inspection systems use LED light source nowadays, heat dissipation is also very important for LED light source. Most visual inspection systems now use sealed LED light source. Such design will inevitably lead to poor heat dissipation of LED chips and circuit boards. If the LED light source is operated for a long time, it is easy to cause the luminous effect to deteriorate (brightness reduction, spectrum shift) due to overheating of the LED light source. In most existing visual inspection systems, the LED light source itself does not have a power switch, and its on and off state is usually controlled by a specially designed circuit or controller. In this way, the LED light source cannot be turned on and off by its own switch key in some actual needs where the light source is not needed, that is, the flexibility of the LED light source is not strong enough.

[0004] Therefore, it is necessary to provide a visual inspection light source that can effectively dissipate heat and improve flexibility. Utility Model Content

[0044] Please refer to Figure 1 - Figure 7 , an embodiment of the present utility model provides a vision detection light source 100 that is easy to dissipate heat, characterized in that the light source 100 includes: a first bracket 10, a frame 20, blades 30, a second bracket 40, and a first substrate 50.

[0045] The frame 20 is fixedly connected to the first bracket 10. The blade 30 is fixedly connected to the frame 20 and is located on the side of the frame 20 away from the first bracket 10. The second bracket 40 is provided with a sliding switch 41. The second bracket 40 is fixedly connected to the frame 20 and is located on the side of the frame 20 away from the blade 30. The first substrate 50 is fixedly connected to the second bracket 40 and is located on the side of the second bracket 40 away from the blade 30. The surface formed by the first substrate 50 is denoted as the first surface S1. The first substrate 50 is electrically connected to the frame 20, and the first substrate 50 drives the blade 30 to rotate through the frame 20.

[0046] Among them, the blade 30 is located on the side of the frame 20 away from the first bracket 10. The rotation of the frame 20 drives the blade 30 to rotate, which helps to increase air flow and promote heat dissipation. The frame 20, as the main heat dissipation structure, is fixed on the first bracket 10 to provide stable support and at the same time transfer heat to the first bracket 10, which helps to dissipate heat. The first substrate 50 is electrically connected to the frame 20, and the motor mechanism of the frame 20 drives the blade 30 to rotate, enhancing the heat dissipation effect. The microcontroller 53 and the drive chip 52 are electrically connected to the first substrate 50 to control the operation of the motor, thereby adjusting the rotation speed of the blade 30 and further optimizing the heat dissipation effect. The sliding switch 41 controls the on / off of the power supply to ensure that the power supply can be manually or automatically turned off when needed to protect the circuit. The side of the second bracket 40 away from the blade 30 is fixedly connected to the frame 20, providing additional stability and supporting the fixation of the first substrate 50 to ensure the structural stability.

[0047] More preferably, the light source 100 further includes: a second substrate 60. The second substrate 60 is fixedly connected to the first bracket 10 and is located on the side of the first bracket 10 away from the frame 20.

[0048] Among them, the second substrate 60 is kept at a certain distance from the frame 20 and the blade 30, avoiding heat concentration in one area, which helps to reduce the local temperature and prevent overheating. The first bracket 10 serves as a heat-conducting medium, which can effectively conduct the heat of the second substrate 60 out, enhancing the overall heat dissipation effect. The second substrate 60 is fixed on the first bracket 10. By using the stable support provided by the first bracket 10, it is ensured that the second substrate 60 will not be affected by vibration or movement during operation, increasing the reliability of the device. Fixing the second substrate 60 on the side of the first bracket 10 away from the frame 20 helps to disperse mechanical stress, reduce the direct load on the frame 20, and extend the service life of the device. The area where the second substrate 60 is far from the frame 20 and the blade 30 can reduce electromagnetic interference and ensure the stability and reliability of the circuit. Fixing the second substrate 60 on the side of the first bracket 10 away from the frame 20 provides more space for circuit design, which helps to arrange components more reasonably and improve the layout efficiency of the overall circuit. Multiple lamp beads 61 are fixed on the second substrate 60 and are effectively cooled by the first bracket 10, keeping the operating temperature of the lamp beads 61 within a reasonable range, thereby improving the efficiency and service life of the light source 100. The second substrate 60 is arranged away from the frame 20, which can avoid the light shielding of the frame 20 structure, ensure that the irradiation range of the light source 100 is more uniform, and is beneficial to improving the visual detection effect.

[0049] More preferably, the second substrate 60 includes: lamp beads 61. A plurality of the lamp beads 61 are located on the side of the second substrate 60 away from the first bracket 10. The lamp beads 61 are bonded to the second substrate 60 and are electrically connected to the substrate.

[0050] Among them, installing the lamp beads 61 on one side of the second substrate 60 enables the first bracket 10 to serve as a heat-conducting support, which helps to quickly conduct the heat generated by the lamp beads 61 and effectively reduce the operating temperature of the lamp beads 61. Through this setting, it is possible to avoid overheating caused by the concentration of the lamp beads 61 in one area, thereby extending the service life of the lamp beads 61 and improving the stability and reliability of the light source 100. Distributing the lamp beads 61 on one side can irradiate the target area more evenly and avoid uneven illumination caused by the concentrated light source 100, thereby improving the accuracy and precision of the visual detection system. Through the electrical connection with the second substrate 60, it is convenient to connect the lamp beads 61 with the control circuit, making the circuit layout more compact and effective. The first bracket 10 serves as a physical isolation layer, which can, to a certain extent, reduce the electromagnetic interference of the lamp bead 61 circuit on other parts and improve the overall electrical performance and stability. The second substrate 60 is fixed on the first bracket 10, providing stable mechanical support, which helps to prevent the lamp beads 61 from being damaged or failing due to vibration or movement during operation.

[0051] Preferably, the second substrate 60 is electrically connected to the first substrate 50. When observed in a direction parallel to the first surface S1, the first substrate 50 is parallel to the second substrate 60.

[0052] Among them, through the electrical connection, the second substrate 60 can transmit signals and power to the control circuit on the first substrate 50. This setting simplifies the circuit design and wiring, making the electrical connection of the system more stable and reliable. The parallel arrangement ensures that the second substrate 60 and the first substrate 50 maintain good alignment during installation and use, which helps to prevent mechanical failure or connection loosening caused by errors or vibrations. The first substrate 50 serves as the main control board of the entire light source 100 system, while the second substrate 60 is responsible for the light source 100 part. Through the parallel arrangement and electrical connection, it facilitates the integration and maintenance of the system, and also supports a more flexible system modular design. The design enables the second substrate 60 to be maintained and replaced relatively independently without affecting the functions and operations of other parts on the first substrate 50, improving the maintainability and serviceability of the system.

[0053] Preferably, the first substrate 50 includes: a terminal 51. The terminal 51 is electrically connected to the first substrate 50, and the terminal 51 is located on a side of the first substrate 50 facing away from the second bracket 40. The light source 100 is powered on through the terminal 51 to connect an external circuit.

[0054] Among them, installing the terminal 51 on one side of the substrate makes it more convenient to connect the external circuit. Users or maintenance personnel can easily access and connect the power supply or control signal lines without having to disassemble the entire light source 100 system. The position selection of the terminal 51 is usually based on the design considerations of the overall structure. Placing it on the back side of the substrate can effectively utilize the space and make the physical layout of the entire system more compact and tidy. The position setting of the terminal 51 makes the maintenance of the light source 100 system more convenient. When maintenance or replacement is required, the maintenance personnel can directly access the terminal 51 to perform circuit connection or replacement operations, improving the maintainability of the system. The position selection of the terminal 51 should ensure firm connection and easy identification. Placing it on the back side can reduce the risk of accidental touch or damage, while ensuring the safety and reliability of the electrical connection.

[0055] Preferably, the first substrate 50 further includes: a driving chip 52 and a microcontroller 53.

[0056] The microcontroller 53 is electrically connected to the first substrate 50, and when observed in a direction perpendicular to the first surface S1, the microcontroller 53 is located on a side of the driving chip 52 facing away from the terminal 51. The microcontroller 53 drives the motor in the frame 20 to rotate through the driving chip 52.

[0057] Among them, the microcontroller 53 usually needs to cooperate closely with the driving chip 52 to control and regulate the operation of the system. By installing the microcontroller 53 on the side of the driving chip 52, the signal connection and communication path between them can be simplified, which helps to reduce the wiring complexity on the circuit board. The microcontroller 53 generates a certain amount of heat during operation. Installing it on the side farther from the terminal 51 can help better distribute and handle the heat in the whole system, avoiding heat concentration from affecting other components or causing unnecessary thermal problems. Installing on the back side of the driving chip 52 can effectively utilize the space of the substrate, making the overall design more compact and efficient. This arrangement also helps to ensure the appropriate distance and mechanical compatibility between the microcontroller 53 and other key components. The position selection of the microcontroller 53 should take into account the convenience of maintenance and service. Placing it on the back side of the driving chip 52 means that when needed, maintenance personnel can directly access the microcontroller 53 for debugging, updating or replacement operations, thus improving the maintainability of the system.

[0058] Preferably, when observed in a direction perpendicular to the first surface S1, the driving chip 52 controls the blade 30 to rotate in a first direction.

[0059] Among them, by designing the driving chip 52 to control the blade 30 to rotate in a consistent direction, it helps to ensure that the mechanical operation of the system is consistent and predictable. Such a setting can avoid chaos and misunderstanding, and simplify the operation and maintenance process. Maintaining the consistency of the rotation direction of the driving chip 52 and the blade 30 helps to reduce the mechanical stress caused by incoordination or inconsistency inside the system. This can improve the long-term stability and reliability of the system and reduce the failure rate. Setting the driving chip 52 in this way enables more precise control of the rotation angle and speed of the blade 30. This is very important for applications such as the vision detection light source 100 that require precise and rapid response. In engineering design, consistency is often regarded as one of the design standardizations and best practices. By ensuring that the driving chip 52 controls the rotation of the blade 30 in a specific direction, the design can better conform to industry standards and general design principles.

[0060] Preferably, the slide switch 41 is electrically connected to the first substrate 50, and when observed in a direction perpendicular to the first surface S1, the slide switch 41 is fixedly connected to the second bracket 40. When the slide switch 41 is turned on, the light source 100 is powered on, and when the slide switch 41 is turned off, the light source 100 is powered off.

[0061] Among them, the on and off of the light source 100 is controlled by a sliding switch 41, which is easy to operate. Users can easily control the power state of the device by moving the switch without using complex control methods or tools. The sliding switch 41 can instantly turn on or off the power. This direct operation method can quickly cut off the power when needed, thus enhancing the safety of the device, especially in emergency situations or when the device needs to be quickly stopped. By controlling the power through the sliding switch 41, the power can be effectively isolated or disconnected, thus simplifying the circuit design and operation process during maintenance and repair, and reducing potential problems caused by operation errors or maintenance requirements. By regularly turning off the light source 100 to save energy or preventing unnecessary energy consumption when not needed, it helps to extend the service life of the light source 100 and other related electronic components and reduce the operating cost. This design allows users to directly participate in the power control of the device, enhancing the user's sense of control and participation in the device functions and improving the overall user experience.

[0062] Preferably, the light source 100 is further provided with a bolt 70 and a nut 80, and the bolt 70 and the nut 80 fix the components of the light source 100.

[0063] Among them, the bolt 70 and the nut 80 provide a reliable connection method, which can effectively fix each component of the light source 100, ensure that each part remains firm during use, and avoid loosening or displacement. In the operating environment, there may be vibrations or impacts. The fixing method of the bolt 70 and the nut 80 can provide higher anti-vibration performance and prevent the device from being damaged or failing due to vibrations. The use of the bolt 70 and the nut 80 makes the connection between components detachable, facilitating the maintenance, repair and replacement of parts of the device, reducing the difficulty and time of maintenance. When the device needs to be adjusted or reconfigured, it can be achieved by simply loosening or tightening the bolt 70 and the nut 80 without complex reassembly of the device. The bolt 70 and the nut 80 are common fasteners, with low cost and easy access. Using these standard parts can reduce the manufacturing cost while ensuring the reliability of the connection. Using the common bolt 70 and nut 80 can reduce the need for specially designed connectors, simplify the supply chain and manufacturing process. The use of the bolt 70 and the nut 80 supports modular design, enabling each component of the light source 100 to be independently manufactured and assembled, thus improving production efficiency and product consistency. This fixing method has high adaptability and can adapt to different installation environments and requirements, enabling the light source 100 to be flexibly applied in different scenarios.

[0064] Preferably, the first bracket 10, the frame 20 and the second bracket 40 each have four through holes, the nut 80 is located between the through holes, and the bolt 70 passes through the through holes and the nut 80 in sequence to fix the first bracket 10, the frame 20 and the second bracket 40.

[0065] Among them, through the way of multiple through holes and bolts 70, the uniform fixation between the first bracket 10, the frame 20 and the second bracket 40 can be ensured, avoiding the situation of excessive local stress or loosening during use. Through the design of bolts 70 and through holes, it can be ensured that the first bracket 10, the frame 20 and the second bracket 40 can be accurately aligned, making the assembly of the device more simple and rapid. During the assembly process, the fine adjustment and adjustment of the structure can be realized by adjusting the tightening degree of the bolts 70 to adapt to different installation requirements and scenarios. When any one of the components needs to be maintained or replaced, only the corresponding bolts 70 need to be disassembled without affecting the structure of other parts, improving the maintenance efficiency and convenience. The simple and effective assembly method can greatly reduce the assembly time and cost and is applicable to the large-scale production environment.

[0066] Thereby, by driving the blade 30 to rotate through the second substrate 60, the light source 100 can dissipate heat effectively, and by the way that the light source 100 is provided with a slide switch 41, the flexibility of the light source 100 is improved.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
