Description

Technical Field

[0001] This utility model relates to the field of light source connection structure technology, and in particular, to a quick-change connection structure for a light source. Background Technology

[0002] In color matching experiments and camera photography tests, a light source (i.e., a lightbox) is required for illumination. However, during testing on automated production lines, a robotic arm is needed to move the light source. In actual production, different light sources need to be used for different test objects, requiring a detachable connection between the light source and the chassis at the end of the robotic arm. Currently, the light source's casing is typically fixed to the chassis using bolts or screws, a method that is cumbersome to install and remove, hindering quick replacement of the light source. Furthermore, to dissipate heat during operation, a cooling fan is usually installed on the light source's casing, increasing both its size and weight, which negatively impacts the stable connection between the robotic arm and the light source, resulting in poor reliability. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a quick-change connection structure for light sources that is easy to replace and uses reliable light sources is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a quick-change connection structure for a light source, including a light source and a chassis. The chassis is used to connect with a robotic arm. The light source includes a housing, a bottom cover installed at one end of the housing, and a lamp plate disposed inside the housing. The space between the lamp plate and the bottom cover inside the housing forms a heat dissipation cavity. A heat sink is disposed inside the heat dissipation cavity. Heat dissipation holes communicating with the heat dissipation cavity are opened on the housing and the bottom cover. The chassis and the bottom cover are magnetically connected. Between the two connecting surfaces of the chassis, one of them is provided with a positioning groove, and the other is provided with a positioning protrusion that is aligned and inserted into the positioning groove. The chassis is disposed away from the heat dissipation holes on the bottom cover.

[0005] Furthermore, between the connecting surfaces of the chassis and the bottom cover, one surface is provided with a magnetic element and the other surface is provided with a magnetic attracting element. The magnetic attracting element corresponds to the magnetic element, and the magnetic element can magnetically attract the magnetic attracting element.

[0006] Furthermore, the end of the positioning protrusion is configured as a spherical structure.

[0007] Furthermore, the length of the positioning protrusion along the direction of insertion into the positioning groove is less than the depth of the positioning groove.

[0008] Furthermore, the chassis has a clearance groove on its side, which is aligned and connected with the heat dissipation hole on the bottom cover.

[0009] Furthermore, there are four magnetic suction components, which are evenly arranged on the chassis. There are also four magnetic elements, each corresponding to one of the magnetic suction components, and each magnetic element is magnetically connected to its corresponding magnetic suction component.

[0010] Furthermore, there are three positioning grooves, which are formed on the bottom cover. There are also three positioning protrusions, which correspond one-to-one with the positioning protrusions. The positioning protrusions are aligned and connected with the corresponding positioning grooves.

[0011] Furthermore, the heat sink is fixedly mounted on the surface of the lamp panel near the bottom cover.

[0012] Furthermore, the light source also includes a light guide plate and a diffuser plate. There are two light guide plates installed inside the housing. Both light guide plates are parallel to each other with respect to the lamp plate. The two light guide plates are arranged alternately on the side of the lamp plate away from the bottom cover. The diffuser plate is disposed on the end of the housing away from the bottom cover.

[0013] The beneficial effects of this utility model are as follows: The quick-change connection structure for the light source of this utility model has heat dissipation holes on the outer shell and bottom cover, eliminating the need for a cooling fan on the light source, reducing its size and weight, lowering the load on the chassis, and making it more reliable in use. At the same time, the chassis and the heat dissipation holes are separated, ensuring that the heat inside the light source is fully dissipated, resulting in good heat dissipation. In addition, when connecting the light source to the chassis, the position is first determined by the positioning groove and positioning protrusion, and then the two are fixed by magnetic connection. Compared with the traditional connection method using bolts or screws and other fasteners, the operation is simpler and more convenient, which is conducive to the quick replacement of the light source.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figure 1 This utility model provides a quick-change connection structure for a light source, including a light source 10 and a chassis 20. The chassis 20 is used to connect with a robotic arm. The light source 10 is detachably mounted on the chassis 20. The detachable connection between the light source 10 and the chassis 20 achieves the purpose of replacing the light source 10.

[0024] Please see Figures 4-6 The light source 10 includes a housing 11, a bottom cover 12, a lamp panel 13, and a heat sink 14. The housing 11 has a square shell structure that extends through both ends. The bottom cover 12 is fixedly installed at one end of the housing 11. The lamp panel 13 is fixedly installed inside the housing 11 at the end near the bottom cover 12. The heat sink 14 is fixedly installed on the surface of the lamp panel 13 near the bottom cover 12. In this embodiment, the space inside the housing 11 between the lamp panel 13 and the bottom cover 12 forms a heat dissipation cavity 110, and the heat sink 14 is located inside the heat dissipation cavity 110. To achieve heat dissipation and prevent the lamp panel 13 from malfunctioning due to high temperature, heat dissipation holes 120 communicating with the heat dissipation cavity 110 are provided on both the housing 11 and the bottom cover 12.

[0025] The lamp board 13 emits light when powered on. During operation, the heat generated by the lamp board 13 is transferred to the heat sink 14, causing the temperature inside the heat dissipation cavity 110 to rise. The heat in the heat dissipation cavity 110 can then escape through the heat dissipation holes 120 on the outer shell 11 and the bottom cover 12, thus achieving heat dissipation and cooling of the lamp board 13. In this embodiment, the lamp board 13 includes an aluminum substrate and LED beads mounted on the aluminum substrate. The aluminum substrate is fixedly connected to the heat sink 14 by bolts. Furthermore, the heat sink 14 is a finned heat sink with a large heat dissipation area, which can effectively dissipate the heat generated by the lamp board 13, resulting in good heat dissipation. In this embodiment, by providing heat dissipation holes 120 on the outer shell 11 and the bottom cover 12, there is no need to install a cooling fan on the outer shell 11, reducing the size and weight of the light source, lowering the load on the robotic arm, and making it more reliable.

[0026] The light source 10 also includes a light guide plate 15 and a diffuser plate 16. Two light guide plates 15 are installed inside the housing 11. Both light guide plates 15 are parallel to the lamp plate 13 and are spaced apart on the side of the lamp plate 13 away from the bottom cover 12. The diffuser plate 16 is located on the end of the housing 11 away from the bottom cover 12. The light guide plate 15 disperses the concentrated light emitted by the LED beads into a uniform surface light source; the diffuser plate 16 disperses the luminous flux, ensuring uniform light distribution. Used in conjunction with the light guide plate 15, the emitted light is more comprehensive and uniform.

[0027] Please see Figure 2 , Figure 3 The chassis 20 and the bottom cover 12 are detachably fixedly connected. Specifically, the chassis 20 is connected to the surface of the bottom cover 12 away from the lamp panel 13, and the chassis 20 and the bottom cover 12 are magnetically connected. Between the two connecting surfaces of the chassis 20 and the bottom cover 12, one of them is provided with a positioning groove 31 and the other is provided with a positioning protrusion 32. The positioning protrusion 32 is aligned and inserted into the positioning groove 31. The chassis 20 is set to avoid the heat dissipation holes 120 on the bottom cover 12.

[0028] When the light source 10 needs to be connected to the chassis 20, the positioning protrusion 32 is first aligned with the positioning groove 31. At this time, the relative position between the light source 10 and the chassis 20 is determined, achieving initial positioning. Then, the chassis 20 is fixed by the magnetic attraction between it and the bottom cover 12. When it is necessary to replace a different light source 10, simply release the magnetic connection between them. Compared with the traditional connection using bolts or screws, the operation is simpler and more convenient, facilitating the quick replacement of the light source 10.

[0029] In this embodiment, a magnetic element 33 is provided on one of the connecting surfaces of the chassis 20 and the bottom cover 12, and a magnetic attracting element 34 is provided on the other. The magnetic attracting element 34 corresponds to the magnetic element 33, and the magnetic element 33 can magnetically attract the magnetic attracting element 34 to achieve a magnetic connection between the chassis 20 and the bottom cover 12. The magnetic element 33 is a magnet, and the magnetic element 34 is made of ferromagnetic materials such as iron, nickel, or chromium.

[0030] In one specific embodiment, there are four magnetic suction members 34, which are evenly arranged on the chassis 20. Correspondingly, there are four magnetic members 33, which correspond one-to-one with the magnetic suction members 34 and are magnetically connected to their respective magnetic suction members 34. Additionally, there are three positioning grooves 31, which are formed on the bottom cover 12. Correspondingly, there are three positioning protrusions 32, which correspond one-to-one with the positioning grooves 31 and are aligned and connected to their respective positioning grooves 31. In this embodiment, the line connecting the centers of the three positioning grooves 31 forms an equilateral triangle.

[0031] In a preferred embodiment, the end of the positioning protrusion 32 is configured with a spherical structure. During the alignment process between the chassis 20 and the bottom cover 12, the positioning protrusion 32 may rub against the surface of the bottom cover 12. The spherical structure at the end of the positioning protrusion 32 can reduce the degree of wear on the bottom cover 12, thereby preventing the bottom cover 12 from being severely scratched. Furthermore, the length of the positioning protrusion 32 along the direction of insertion into the positioning groove 31 is less than the depth of the positioning groove 31, so that when the positioning protrusion 32 is inserted into the positioning groove 31, the magnetic attracting element 34 and the magnetic element 33 can be closer together, the magnetic attraction is more sufficient, and thus the magnetic attraction strength is ensured.

[0032] In this embodiment, a clearance groove 210 is provided on the side of the chassis 20. The clearance groove 210 is aligned and communicates with the heat dissipation hole 120 on the bottom cover 12. Thus, when the chassis 20 is connected to the bottom cover 12, the clearance groove 210 prevents the chassis 20 from blocking the heat dissipation hole 120 on the bottom cover 12, which facilitates the dissipation of heat in the heat dissipation cavity 110 through the heat dissipation hole 120. In other embodiments not shown, a cooling fan can also be installed on the robotic arm. The air outlet of the cooling fan can be directed away from the heat dissipation hole 120. In this way, when the cooling fan is started, the heat at the location of the heat dissipation hole 120 is carried away by the air flow, thereby accelerating heat dissipation.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
