[0001] This invention relates to the field of heat dissipation technology, and in particular to a heat dissipation component, a light source component, and a vision component. [Background Technology]

[0002] Existing die bonders are equipped with vision devices for acquiring image information of the substrate and the chip; in order to improve the quality of the image information acquired by the vision devices, a light source component is usually provided for the vision devices.

[0003] However, during use, the light source component generates a lot of heat, and usually needs to be equipped with a heat dissipation component. However, the heat dissipation airflow of the existing heat dissipation component will affect the vision component that works with the light source component, resulting in a decrease in the clarity of the image information acquired by the vision component. [Summary of the Invention]

[0004] To address the issue that existing air-cooled heat dissipation components of die bonders can negatively impact vision components, this invention provides a heat dissipation component, a light source, and a vision component.

[0005] The present invention provides a heat dissipation component, comprising a main body, wherein the main body includes a stacked heat dissipation section and a connecting section, the connecting section being used to install a light source for use with a vision device; the heat dissipation section has a hollow section extending through the heat dissipation section along the stacking direction for installing the vision device; the connecting section has a clearance hole corresponding to the hollow section for avoiding obstruction of the vision device's shooting path; the heat dissipation section has an air duct surrounding the hollow section and communicating with the outside, the air duct not communicating with the hollow section; the path of the air duct is set corresponding to the position of the light source on the connecting section.

[0006] Preferably, the air duct is spirally arranged, and the number of spiral layers on one side of the air duct is greater than or equal to two layers.

[0007] Preferably, the connecting part is provided with a receiving cavity for installing a light source, and the position of the air duct projected on the connecting part corresponds to the position of the receiving cavity.

[0008] Preferably, the receiving cavity is arranged around the clearance hole.

[0009] Preferably, the connecting part includes a heat-conducting element, which is disposed at a position corresponding to the air duct in the connecting part.

[0010] Preferably, the heat dissipation part and the connecting part are detachably connected.

[0011] Preferably, the connection between the heat dissipation part and the connecting part is provided with a sealing structure.

[0012] Preferably, the main body is further provided with a temperature detector for detecting the temperature of the connection part and a wind speed controller for controlling the flow rate of the heat dissipation airflow, wherein the temperature detector and the wind speed controller are electrically connected.

[0013] To solve the above-mentioned technical problems, the present invention also provides a light source assembly, including a light source and the above-mentioned heat dissipation assembly, wherein the light source is disposed within the connecting portion.

[0014] To solve the above-mentioned technical problems, the present invention also provides a vision component, including a vision device and the above-mentioned light source component, wherein the vision device is disposed within the hollow portion, and the light source component is used to assist the vision device in acquiring external image information.

[0015] Compared with the prior art, the heat dissipation component, light source component, and vision component of the present invention have the following advantages:

[0016] 1. The heat dissipation component of the present invention provides a hollow section on the heat dissipation part, and the hollow section is not connected to the air duct. In existing air-cooled heat dissipation components, the hollow section is connected to the air duct, so the heat dissipation airflow can enter the hollow section. This inevitably affects the vision device that works with the light source component in the hollow section, resulting in a decrease in the clarity of the image information acquired by the vision component. The present solution can effectively prevent the heat dissipation airflow in the air duct from flowing into the hollow section, thus solving the problem that the air-cooled heat dissipation component will affect the vision component.

[0017] 2. The number of spiral layers on one side of the air duct of the present invention is greater than or equal to two layers. This design can increase the contact area between the heat dissipation airflow and the heat sink, thereby enhancing the heat dissipation performance of the heat dissipation component. It can be understood that increasing the number of spiral layers on one side of the air duct means increasing the number of spiral layers on one side of the heat sink. Since the heat sink and the air duct are spiral in shape, there are air ducts on both sides of the heat sink, and heat dissipation airflow will pass through both sides of the heat sink. Therefore, increasing the number of spiral layers on one side of the air duct can effectively improve the heat dissipation performance of the heat dissipation component.

[0018] 3. The position of the air duct projected on the connecting part of the present invention corresponds to the position of the receiving cavity. This design allows the heat of the light source to be better conducted into the air duct, which is beneficial to enhancing the heat dissipation performance of the heat dissipation component.

[0019] 4. The receiving cavity of the present invention is surrounded by the avoidance hole, that is, the light source of the present invention is surrounded by the avoidance hole. This design can prevent the light source from blocking the shooting path of the vision component and affecting the operation of the vision component; the air duct is surrounded by the hollow part. This design is conducive to optimizing the structure of the heat dissipation component and allowing the air duct to better dissipate heat from the light source.

[0020] 5. The heat-conducting component of the present invention allows the heat emitted by the light source to be better conducted to the heat sink, further enhancing the heat dissipation performance of the heat dissipation component.

[0021] 6. The heat dissipation part and the connecting part of the present invention are detachably connected, which facilitates later maintenance and reduces maintenance costs.

[0022] 7. The connection between the heat dissipation part and the connecting part of the present invention is provided with a sealing structure. This design helps to ensure the sealing of the heat dissipation part and further ensures that the heat dissipation airflow will not leak out, thus avoiding the adverse effects of heat dissipation airflow leakage on the visual components.

[0023] 8. The heat dissipation component of the present invention can automatically adjust the heat dissipation airflow through a temperature detector and a wind speed controller, which helps to improve the automation level of the heat dissipation component.

[0024] 9. A light source assembly of the present invention has the same beneficial effects as the heat dissipation assembly described above.

[0025] 10. A visual component of the present invention has the same beneficial effects as the light source component described above. [Attached Image Description]

Detailed Implementation Methods

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The terms “vertical,” “horizontal,” “left,” “right,” “up,” “down,” “upper left,” “upper right,” “lower left,” “lower right,” “lower left,” “lower right,” and similar expressions used in this article are for illustrative purposes only.

[0039] Please combine Figure 1 and Figure 2 The first embodiment of the present invention provides a heat dissipation assembly 100, including a main body 1. The main body 1 includes a heat dissipation part 11 and a connecting part 12 stacked together. The connecting part 12 is used to install a light source for use with a vision device. The heat dissipation part 11 is provided with a hollow part 114 that runs through the heat dissipation part along the stacking direction for installing the vision device. The connecting part 12 is provided with a clearance hole 121 corresponding to the hollow part 114 for avoiding the shooting path of the vision device. The heat dissipation part 11 is provided with an air duct 113 that surrounds the hollow part 114 and communicates with the outside. The air duct 113 is not connected to the hollow part 114. The path of the air duct 113 is set to correspond to the position of the light source on the connecting part 12.

[0040] Understandably, the heat dissipation assembly 100 of the present invention provides a hollow portion 114 on the heat dissipation part 11, and the hollow portion 114 is not connected to the air duct 113. In the existing air-cooled heat dissipation assembly 100, the hollow portion 114 is connected to the air duct 113, so the heat dissipation airflow can enter the hollow portion 114, which inevitably affects the vision device inside the hollow portion 114, resulting in a decrease in the clarity of the image information acquired by the vision device. However, the present solution can effectively prevent the heat dissipation airflow in the air duct 113 from easily flowing into the hollow portion 114, thus solving the problem that the air-cooled heat dissipation assembly 100 will affect the vision device 300.

[0041] Specifically, in this embodiment, the connecting part 12 is located below the heat dissipation part 11, the hollow part 114 is a cylindrical hole that penetrates the middle region of the heat dissipation part 11, and the clearance hole 121 is a cylindrical hole that penetrates the middle region of the connecting part 12. The axis of the hollow part 114 coincides with that of the connecting part 12 and the cross-sectional diameter is equal.

[0042] Furthermore, the heat dissipation part 11 includes a body 110 and a top cover 111 disposed on the body 110. The air duct 113 is disposed inside the body 110. The top cover 111 and the connecting part 12 respectively seal the opposite sides of the air duct 113. The position of the air duct 113 projected on the connecting part 12 corresponds to the position of the light source on the connecting part 12.

[0043] Understandably, the present invention seals the upper and lower openings of the air duct 113 by sealing the top cover 111 and the connecting part 12 respectively, thereby sealing the heat dissipation airflow inside the heat dissipation part 11 and preventing the heat dissipation airflow from leaking out and affecting the outside world.

[0044] Furthermore, the heat sink 112 within the air duct 113 extends spirally from the top cover 111 towards the connecting portion 12. It is understood that the heat sink 112 extending spirally from the top cover 111 towards the connecting portion 12 within the air duct 113 of the present invention effectively increases the heat dissipation area of ​​the heat dissipation assembly 100, thereby further enhancing the heat dissipation performance of the heat dissipation assembly 100.

[0045] Furthermore, the air duct 113 is defined by a heat sink 112 extending from the top cover 111 to the connecting portion 12. It is understood that the air duct 113 of the present invention is defined by the heat sink 112 extending from the top cover 111 to the connecting portion 12, so that heat generated by the light source can be conducted along the heat sink to the entire air duct 113, ensuring that the heat dissipation performance of the heat dissipation assembly 100 is fully utilized.

[0046] Optionally, the top cover 111 and the heat sink 112 are fixedly connected, or the top cover 111 and the heat sink 112 are an integral structure. Specifically, in this embodiment, the top cover 111 and the heat sink 112 are fixedly connected.

[0047] Furthermore, a sealing structure is provided at the connection between the heat dissipation part 11 and the connecting part 12. This design helps to ensure the airtightness of the heat dissipation part 11, further ensuring that the heat dissipation airflow will not leak out, thus avoiding any adverse effects on the visual components caused by the leakage of heat dissipation airflow.

[0048] Specifically, in this embodiment, the sealing structure is a sealing ring. It is understood that in other embodiments, a sealing groove for cooperating with the sealing ring may be provided on the heat dissipation part 11 or the connecting part 12; or other sealing structures may be used.

[0049] Furthermore, the heat dissipation part 11 and the connecting part 12 are detachably connected. This facilitates later maintenance and reduces maintenance costs. Specifically, in this embodiment, the heat dissipation part 11 and the connecting part 12 are connected by a threaded component; the outer walls of the heat dissipation part 11 and the connecting part 12 are respectively provided with protrusions, and threaded holes and mating holes for engaging with the threaded component are respectively provided on the corresponding protrusions.

[0050] Please continue reading. Figure 2 The air duct 113 is spirally arranged, with two or more spiral layers on one side. Understandably, this design effectively increases the total length of the air duct 113, thereby enhancing the heat dissipation performance of the heat dissipation component 100.

[0051] This design increases the contact area between the heat dissipation airflow and the heat sink 112, thereby enhancing the heat dissipation performance of the heat dissipation component 100. It is understandable that increasing the number of spiral layers on one side of the air duct 113 means increasing the number of spiral layers on one side of the heat sink 112. Since the heat sink 112 and the air duct 113 are spiral-shaped, and air ducts 113 exist on both sides of the heat sink 112, heat dissipation airflow passes over both sides of the heat sink 112. Therefore, increasing the number of spiral layers on one side of the air duct 113 effectively improves the heat dissipation performance of the heat dissipation component 100.

[0052] Specifically, in this embodiment, the single-sided spiral layer of the air duct 113 is three layers; the overall outer contour of the air duct 113 is elliptical. It is understood that in other embodiments, the overall outer contour of the air duct 113 may also be circular or square or other shapes, and the direction of the air duct 113 may also adopt other types of straight or curved lines, such as serpentine lines.

[0053] Furthermore, the air inlet 1131 and air outlet 1132 of the air duct 113 are both located on the top surface of the top cover 111; or, the air inlet 1131 of the air duct 113 is located on the side wall of the top cover 111, and the air outlet 1132 of the air duct 113 is located on the top surface of the top cover 111. This design facilitates the diversification of the structure of the heat dissipation component 100.

[0054] Specifically, in this embodiment, the air inlet 1131 and the air outlet 1132 of the air duct 113 are both located on the top surface of the top cover 111. The air inlet 1131 is located near the outer edge of the top cover 111, and the air outlet 1132 is located near the middle area of ​​the top cover 111.

[0055] Understandably, the air inlet 1131 of the air duct 113 is connected to the air intake pipe, and the end of the air intake pipe away from the air inlet 1131 is connected to an airflow delivery device. In other embodiments, a blower device can also be installed to generate cooling airflow.

[0056] Please combine Figures 1 to 3The connecting portion 12 is provided with a receiving cavity 122 for mounting a light source. A heat-conducting element 123 is provided on the connecting portion 12 at a position corresponding to the air duct 113. A portion of the heat-conducting element 123 is located within the receiving cavity 122, and the light source within the receiving cavity 122 is connected to the heat-conducting element 123. It can be understood that the heat-conducting element 123 on the connecting portion 12 of the present invention allows the heat emitted by the light source to be better conducted to the heat sink 112, further enhancing the heat dissipation performance of the heat dissipation assembly 100.

[0057] Furthermore, the cavity 122 has an inlet / outlet hole 124 on its side wall near the outside for the light source to lead out its wire.

[0058] Furthermore, the receiving cavity 122 is arranged around the obstruction hole 121, and the air duct 113 is arranged around the hollow portion 114. It can be understood that the arrangement of the receiving cavity 122 around the obstruction hole 121 in this invention means that the light source of this invention is arranged around the obstruction hole 121. This design can prevent the light source from blocking the shooting path of the vision component 300 and affecting the operation of the vision component 300. The arrangement of the air duct 113 around the hollow portion 114 is beneficial for optimizing the structure of the heat dissipation component 100, allowing the air duct 113 to better dissipate heat from the light source.

[0059] Furthermore, the heat-conducting component 123 has a mating groove 1231 on the side near the air duct 113 for mating with the heat sink 112.

[0060] Understandably, the mating groove 1231 can mate with the heat sink 112 to facilitate assembly. At the same time, it can increase the contact area between the connecting part 12 and the heat sink 112, thereby accelerating the heat conduction speed and further enhancing the heat dissipation performance of the heat dissipation component 100.

[0061] In other embodiments, the heat-conducting element 123 and the heat sink 112 can also be integrally formed.

[0062] Furthermore, the main body 1 is also equipped with a temperature detector for detecting the temperature of the connection part 12 and a fan speed controller for controlling the airflow speed of the heat dissipation component. The temperature detector and the fan speed controller are electrically connected. The heat dissipation component 100 of the present invention can realize automatic adjustment of the heat dissipation airflow through the temperature detector and the fan speed controller, which is beneficial to improving the automation level of the heat dissipation component 100.

[0063] Furthermore, the temperature detector can monitor the temperature of the receiving cavity 122 and / or the temperature of the heat-conducting component 123 in real time. When the temperature value detected by the temperature detector is greater than the first threshold, the airflow delivery device is activated to introduce heat dissipation airflow into the air duct 113 and make the flow rate of the heat dissipation airflow reach the first preset value to dissipate heat from the heat sink 112. When the temperature value detected by the temperature detector is greater than the second threshold, the flow rate of the heat dissipation airflow is adjusted by the wind speed controller in conjunction with the airflow delivery device and made the flow rate of the heat dissipation airflow reach the second preset value to enhance the heat dissipation performance of the heat dissipation component 100. When the temperature value detected by the temperature detector is less than the first threshold, the airflow delivery device will be controlled to stop delivering the heat dissipation airflow.

[0064] Please combine Figure 1 and Figure 4 The second embodiment of the present invention provides a light source assembly 200, including a light source 1001 and the above-mentioned heat dissipation assembly 100. The light source 1001 is disposed in the connecting part, and the heat dissipation assembly 100 can effectively dissipate heat from the light source 1001, avoiding the impact on the service life of the light source assembly 200 due to excessive heat generation.

[0065] Please combine Figure 1 , Figure 4 and Figure 5 The third embodiment of the present invention provides a vision component 300, including a vision device 2001 and the aforementioned light source component 200. The vision device 2001 is disposed in the hollow portion 114, and the light source component 200 is used to assist the vision device 2001 in acquiring external image information.

This inevitably affects the vision device that works with the light source component in the hollow section, resulting in a decrease in the clarity of the image information acquired by the vision component. The present solution can effectively prevent the heat dissipation airflow in the air duct from flowing into the hollow section, thus solving the problem that the air-cooled heat dissipation component will affect the vision component.

[0068] 2. The number of spiral layers on one side of the air duct of the present invention is greater than or equal to two layers. This design can increase the contact area between the heat dissipation airflow and the heat sink, thereby enhancing the heat dissipation performance of the heat dissipation component. It can be understood that increasing the number of spiral layers on one side of the air duct means increasing the number of spiral layers on one side of the heat sink. Since the heat sink and the air duct are spiral in shape, there are air ducts on both sides of the heat sink, and heat dissipation airflow will pass through both sides of the heat sink. Therefore, increasing the number of spiral layers on one side of the air duct can effectively improve the heat dissipation performance of the heat dissipation component.

[0069] 3. The position of the air duct projected on the connecting part of the present invention corresponds to the position of the receiving cavity. This design allows the heat of the light source to be better conducted into the air duct, which is beneficial to enhancing the heat dissipation performance of the heat dissipation component.

This design can prevent the light source from blocking the shooting path of the vision component and affecting the operation of the vision component; the air duct is surrounded by the hollow part. This design is conducive to optimizing the structure of the heat dissipation component and allowing the air duct to better dissipate heat from the light source.
