Description

Technical Field

[0001] The present application belongs to the technical field of imaging lighting, and specifically relates to a lighting auxiliary imaging device. Background Art

[0002] CCD is a photosensitive coupled component, also known as a charge coupled device. It is an integrated circuit that can sense light and convert video into digital signals. It is widely used in digital photography, optical telemetry technology, optical and spectrum telescopes, and high-speed photography technology, such as lucky imaging. Monochromatic light is helpful for some morphological surface analysis, which can improve resolution and image quality. Therefore, auxiliary lighting mechanisms are usually set in some CCD imaging devices to use the monochromatic light of the auxiliary lighting mechanism to improve resolution and image quality.

[0003] In the related art, the auxiliary lighting mechanism is usually a ring-shaped light strip coaxially arranged at the bottom of the CCD, so that the light emitted by the ring-shaped light strip can surround the scanned object; however, since the irradiation position of the ring-shaped light strip cannot be adjusted, when imaging different scanned objects, the irradiation position of the auxiliary lighting mechanism needs to be adjusted according to the size of the scanned object, which results in poor flexibility of the auxiliary lighting mechanism, thereby affecting the imaging quality of the CCD. Utility Model Content

[0004] The present application provides an illumination auxiliary imaging device to increase the flexibility of an auxiliary illumination mechanism, thereby ensuring the imaging quality of a CCD.

[0005] The technical solution adopted in this application is:

[0006] A lighting auxiliary imaging device comprises a mounting ring, a monochromatic light emitter arranged on the mounting ring, a lens located at the top of the mounting ring and a CCD arranged on the top of the lens, wherein the lens and the CCD are coaxially arranged with the mounting ring, an even number of the monochromatic light emitters are evenly spaced along the circumference of the mounting ring, and each of the monochromatic light emitters can move relative to the mounting ring so that the irradiation position of each of the monochromatic light emitters can be adjusted.

[0007] By adopting the above-mentioned technical solution, since each monochromatic light emitter in the present application can be installed to move relative to the ring, the irradiation position of each monochromatic light emitter can be adjusted. That is to say, when imaging different scanned objects, the irradiation position of the monochromatic light emitter can be adjusted as needed to ensure the imaging resolution and imaging quality, thereby increasing the flexibility of the monochromatic light emitter and solving the problem of the CCD imaging quality being affected by the inability to adjust the illumination position, thereby ensuring the imaging quality and resolution of the CCD.

[0008] Optionally, each of the monochromatic light emitters is hinged to the mounting ring, and the rotation axis of each of the monochromatic light emitters is arranged perpendicular to the axial direction of the mounting ring, so that when the monochromatic light emitter rotates relative to the mounting ring, the irradiation position of the monochromatic light emitter changes.

[0009] By adopting the above technical solution, since each monochromatic light emitter is hinged to the mounting ring, when adjusting the monochromatic light emitter, it is only necessary to rotate the monochromatic light emitter, so that the monochromatic light emitter and the mounting ring rotate relative to each other, so that the irradiation position of the monochromatic light emitter changes. In this process, it is only necessary to rotate the monochromatic light emitter, thereby achieving the effect of facilitating the adjustment of the irradiation position of the monochromatic light emitter.

[0010] Optionally, the mounting ring is provided with a plurality of mounting blocks, and the mounting blocks are arranged in one-to-one correspondence with the monochromatic light emitters, each of the monochromatic light emitters is hinged to the corresponding mounting block, and each of the mounting blocks can move relative to the mounting ring.

[0011] By adopting the above technical solution, since the monochromatic light emitter is hinged to the mounting block, when the monochromatic light emitter is adjusted, the monochromatic light emitter and the mounting block rotate relative to each other, that is, the relative position of the monochromatic light emitter and the mounting block changes, so as to achieve the adjustment of the irradiation position of the monochromatic light emitter; if the irradiation position of the monochromatic light emitter still cannot meet the demand after the monochromatic light emitter is adjusted to the extreme position, the mounting block can be adjusted at this time so that the mounting block drives the monochromatic light emitter to move, so that the irradiation position of the monochromatic light emitter can be further adjusted, thereby further increasing the flexibility of the monochromatic light emitter, so as to further ensure the imaging resolution and imaging quality of the CCD.

[0012] Optionally, the mounting block is provided with a waist-shaped hole and a fixing bolt passing through the waist-shaped hole, the fixing bolt is threadedly connected to the mounting ring, the fixing bolt has a locking state in which the bolt head is pressed against the mounting block and an adjustment state in which the bolt head is separated from the mounting block, and when the fixing bolt is in the adjustment state, the mounting block and the mounting ring can move relative to each other.

[0013] By adopting the above technical solution, when adjusting the mounting block, the fixing bolt is first screwed to separate the bolt head of the fixing bolt from the mounting block, and then the fixing bolt is moved to the adjustment state, and then the mounting block is pushed to make the fixing bolt and the waist-shaped hole slide relative to each other, and then the relative position of the mounting block and the mounting ring changes; after the relative position of the mounting block and the mounting ring is adjusted, the fixing bolt is rotated in the opposite direction to make the bolt head of the fixing bolt press against the mounting block, and then the fixing bolt is moved to the locking state to complete the adjustment of the mounting block. In this process, it is only necessary to screw the fixing bolt and push the mounting block, thereby achieving the effect of facilitating the adjustment of the mounting block and increasing the connection stability between the mounting block and the mounting ring.

[0014] Optionally, the mounting block is provided with a strip hole, the monochromatic light emitter is passed through the strip hole, and hinge shafts passing through the wall of the strip hole are provided on opposite sides of the monochromatic light emitter.

[0015] By adopting the above technical solution, since the monochromatic light emitter is inserted into the strip hole, the position of the monochromatic light emitter is made as close to the central area of ​​the mounting block as possible, so as to avoid the situation where the volume of the lighting auxiliary imaging device increases due to the monochromatic light emitter being arranged on the outside of the mounting block, thereby achieving the effect of facilitating the miniaturization design of the lighting auxiliary imaging device.

[0016] Optionally, connecting holes are provided on opposite sides of the strip-shaped hole, the two hinge shafts are respectively passed through the two connecting holes, and a damping member in contact with the hole wall of the connecting hole is sleeved on the hinge shaft.

[0017] By adopting the above technical solution, when the monochromatic light emitter is rotated, the monochromatic light emitter drives the hinge shaft to rotate, and the hinge shaft drives the damping member to rotate, thereby causing the damping member and the hole wall of the connecting hole to rotate relative to each other. By setting the damping member, the friction between the hinge shaft and the hole wall of the connecting hole is increased to avoid the situation where the monochromatic light emitter rotates under the action of its own gravity after being adjusted to the set position, thereby increasing the stability of the monochromatic light emitter to further ensure the imaging resolution and imaging quality of the CCD.

[0018] Optionally, the mounting ring is provided with a plurality of avoidance notches, and the avoidance notches are arranged in one-to-one correspondence with the monochromatic light emitters.

[0019] By adopting the above technical solution, since the mounting ring is provided with an avoidance gap corresponding to the monochromatic light emitter, the monochromatic light emitter can be closer to the central axis of the mounting ring, thereby further reducing the volume of the lighting auxiliary imaging device, and at the same time reducing the weight of the lighting auxiliary imaging device.

[0020] Optionally, the mounting ring is provided with a support rod, and the CCD is arranged on the support rod.

[0021] By adopting the above technical solution, since the CCD is arranged on the support rod, the CCD is integrated into the mounting ring, thereby reducing the number of assembly parts required when installing the lighting auxiliary imaging device to other structures, so as to achieve the effect of facilitating the installation of the lighting auxiliary imaging device to other structures, while ensuring that the CCD and the lens are in a coaxial state with the mounting ring.

[0022] Optionally, the CCD is provided with a connecting bracket, the connecting bracket is sleeved on the supporting rod, and the connecting bracket is threadedly connected with a locking rod capable of pressing against the supporting rod.

[0023] By adopting the above technical solution, when adjusting the CCD, first turn the locking rod to separate the locking rod from the support rod, and then slide the CCD, so that the CCD drives the connecting bracket to move, and the connecting bracket and the support rod move relative to each other, so as to adjust the relative position of the CCD and the mounting ring; after adjusting the position of the CCD, turn the locking rod in the opposite direction to make the locking rod press against the support rod to complete the adjustment of the CCD. In the process of adjusting the position of the CCD, it is only necessary to turn the locking rod and slide the CCD, thereby achieving the effect of facilitating the adjustment of the position of the CCD.

[0024] Optionally, a plurality of mounting holes are provided on the circumference of the mounting ring so as to allow the mounting ring to be connected to an external structure.

[0025] By adopting the above technical solution, when installing the lighting auxiliary imaging device to the external structure, it is only necessary to extend the rod-shaped structure on the external structure into the mounting hole to achieve the effect of facilitating the installation of the lighting auxiliary imaging device to the external structure. At the same time, the provision of multiple mounting holes increases the connection stability between the lighting auxiliary imaging device and the external structure.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0027] 1. The lighting-assisted imaging device in the present application includes a mounting ring, a monochromatic light emitter arranged on the mounting ring, a lens located at the top of the mounting ring and a CCD arranged on the top of the lens. The lens and the CCD are coaxially arranged with the mounting ring. An even number of monochromatic light emitters are evenly spaced along the circumference of the mounting ring, and each monochromatic light emitter can move relative to the mounting ring so that the irradiation position of each monochromatic light emitter can be adjusted. That is to say, when imaging different scanned objects, the irradiation position of the monochromatic light emitter can be adjusted as needed to ensure the resolution and quality of the imaging, thereby increasing the flexibility of the monochromatic light emitter and solving the problem of affecting the imaging quality of the CCD due to the inability to adjust the illumination position, thereby ensuring the imaging quality and resolution of the CCD.

[0028] 2. The monochromatic light emitters in the present application are all hinged to the mounting ring, and the rotation axis of each monochromatic light emitter is perpendicular to the axial setting of the mounting ring, so that when the monochromatic light emitter and the mounting ring rotate relative to each other, the irradiation position of the monochromatic light emitter changes, and then when the monochromatic light emitter is adjusted, it is only necessary to rotate the monochromatic light emitter, so that the monochromatic light emitter and the mounting ring rotate relative to each other, so that the irradiation position of the monochromatic light emitter changes. In this process, it is only necessary to rotate the monochromatic light emitter, thereby achieving the effect of facilitating the adjustment of the irradiation position of the monochromatic light emitter.

[0044] Reference Figures 1 to 6 , discloses a lighting-assisted imaging device, which includes a mounting ring 1, a monochromatic light emitter 2 arranged on the mounting ring 1, a lens 3 located at the top of the mounting ring 1, and a CCD 4 arranged on the top of the lens 3, the lens 3 and the CCD 4 are both coaxially arranged with the mounting ring 1, an even number of monochromatic light emitters 2 are evenly spaced along the circumference of the mounting ring 1, and each monochromatic light emitter 2 can move relative to the mounting ring 1 so that the irradiation position of each monochromatic light emitter 2 can be adjusted.

[0045] It should be noted that CCD is the abbreviation of Charge-coupled Device, which represents a photosensitive coupled device.

[0046] Since each monochromatic light emitter 2 in the present application can be installed relative to the ring 1, the irradiation position of each monochromatic light emitter 2 can be adjusted. That is to say, when imaging different scanned objects, the irradiation position of the monochromatic light emitter 2 can be adjusted as needed to ensure the imaging resolution and imaging quality, thereby increasing the flexibility of the monochromatic light emitter 2 and solving the problem of the imaging quality of CCD4 being affected by the inability to adjust the illumination position, thereby ensuring the imaging quality and resolution of CCD4.

[0047] The present application does not specifically limit the structure of the monochromatic light emitter 2. Preferably, the monochromatic light emitter 2 is an LD laser with a fiber-coupled output, which has the characteristics of small size and simple driving and power supply, so as to facilitate its integration into the mounting ring 1. At the same time, the laser is also the most ideal monochromatic light source to ensure the imaging resolution and imaging quality of the lighting-assisted imaging device. In other embodiments, the monochromatic light emitter 2 can also be an LED lamp.

[0048] The present application does not impose any specific limitation on the number of the monochromatic light emitters 2, which can be as follows: Figure 1 and Figure 2 Although four are shown, two or even six may also be provided.

[0049] The present application does not specifically limit the method of mounting the monochromatic light emitter 2 to the mounting ring 1, and it may adopt any one of the following embodiments:

[0050] Embodiment 1. In this embodiment, each monochromatic light emitter 2 is hinged to the mounting ring 1, and the rotation axis of each monochromatic light emitter 2 is arranged perpendicular to the axial direction of the mounting ring 1, so that when the monochromatic light emitter 2 rotates relative to the mounting ring 1, the irradiation position of the monochromatic light emitter 2 changes.

[0051] It can be understood that each monochromatic light emitter 2 is directly hinged to the mounting ring 1, so that when adjusting the monochromatic light emitter 2, it is only necessary to rotate the monochromatic light emitter 2, so that the monochromatic light emitter 2 and the mounting ring 1 rotate relative to each other, so that the irradiation position of the monochromatic light emitter 2 changes. In this process, it is only necessary to rotate the monochromatic light emitter 2, thereby achieving the effect of facilitating the adjustment of the irradiation position of the monochromatic light emitter 2.

[0052] Implementation method 2. In this implementation method, refer to Figures 1 to 4 The mounting ring 1 is provided with a plurality of mounting blocks 11, and the mounting blocks 11 are arranged one by one corresponding to the monochromatic light emitters 2. Each monochromatic light emitter 2 is hinged to the corresponding mounting block 11, and each mounting block 11 can move relative to the mounting ring 1.

[0053] It can be understood that each monochromatic light emitter 2 is connected to the mounting ring 1 via a mounting block 11, and each monochromatic light emitter 2 is hinged to the corresponding mounting block 11, so that when the monochromatic light emitter 2 is adjusted, the monochromatic light emitter 2 and the mounting block 11 rotate relative to each other, that is, the relative position of the monochromatic light emitter 2 and the mounting block 11 changes, so as to adjust the irradiation position of the monochromatic light emitter 2; if the irradiation position of the monochromatic light emitter 2 still cannot meet the requirements after the monochromatic light emitter 2 is adjusted to the extreme position, the mounting block 11 can be adjusted at this time, so that the mounting block 11 drives the monochromatic light emitter 2 to move, so that the irradiation position of the monochromatic light emitter 2 is further adjusted, so as to further increase the adjustment range of the irradiation position of the monochromatic light emitter 2, and then further increase the flexibility of the monochromatic light emitter 2, so as to further ensure the imaging resolution and imaging quality of the CCD4.

[0054] Further, see Figure 2 , Figure 3 and Figure 4 The mounting block 11 is provided with a waist-shaped hole 111 and a fixing bolt passing through the waist-shaped hole 111. The fixing bolt is threadedly connected to the mounting ring 1. The fixing bolt has a locking state in which the bolt head is tightly pressed against the mounting block 11 and an adjustment state in which the bolt head is separated from the mounting block 11. When the fixing bolt is in the adjustment state, the mounting block 11 and the mounting ring 1 can move relative to each other.

[0055] When adjusting the mounting block 11, the fixing bolt is first tightened to separate the bolt head of the fixing bolt from the mounting block 11, and then the fixing bolt moves to the adjustment state, and then the mounting block 11 is pushed to make the fixing bolt and the waist-shaped hole 111 slide relative to each other, and then the relative position of the mounting block 11 and the mounting ring 1 changes; after the relative position of the mounting block 11 and the mounting ring 1 is adjusted, the fixing bolt is rotated in the opposite direction to make the bolt head of the fixing bolt press against the mounting block 11, and then the fixing bolt moves to the locking state to complete the adjustment of the mounting block 11. In this process, it is only necessary to tighten the fixing bolt and push the mounting block 11, thereby achieving the effect of facilitating the adjustment of the mounting block 11 and increasing the connection stability between the mounting block 11 and the mounting ring 1.

[0056] Better, refer to Figure 2 , Figure 3 and Figure 4 The fixing bolt is a hexagon socket bolt, the waist-shaped hole 111 is a stepped hole, and the aperture of the waist-shaped hole 111 close to the mounting ring 1 is smaller than the aperture of the waist-shaped hole 111 away from the mounting ring 1. As a result, when the fixing bolt is in a locked state, the bolt head of the fixing bolt can be hidden in the waist-shaped hole 111, so as to increase the aesthetics of the lighting auxiliary imaging device and increase the connection stability between the mounting block 11 and the mounting ring 1.

[0057] Further, refer to Figure 2 , Figure 3 and Figure 4 The mounting block 11 is provided with a bar hole 112, and the monochromatic light emitter 2 is passed through the bar hole 112. Both opposite sides of the monochromatic light emitter 2 are provided with hinge shafts 21 passed through the wall of the bar hole 112, so that the position of the monochromatic light emitter 2 is as close to the central area of ​​the mounting block 11 as possible to avoid the increase in the volume of the lighting-assisted imaging device due to the monochromatic light emitter 2 being arranged on the outside of the mounting block 11, thereby achieving the effect of facilitating the miniaturization design of the lighting-assisted imaging device.

[0058] Better, refer to Figure 3 , Figure 4 and Figure 5 , connecting holes 113 are provided on the opposite sides of the strip hole 112, and two hinge shafts 21 are respectively inserted into the two connecting holes 113, and the hinge shafts 21 are sleeved with damping members in contact with the hole walls of the connecting holes 113 to increase the friction between the hinge shaft 21 and the connecting holes 113 to avoid the situation where the monochrome light emitter 2 rotates under the action of its own gravity after the monochrome light emitter 2 is adjusted to the set position, thereby increasing the stability of the monochrome light emitter 2 to further ensure the imaging resolution and imaging quality of the CCD4.

[0059] The present application does not specifically limit the structure of the damping member. Preferably, the damping member is a silicone damping ring to facilitate the assembly of the lighting-assisted imaging device and reduce the production cost of the lighting-assisted imaging device. In other implementation examples, the damping member can also be a rubber sleeve sleeved outside the hinge shaft 21.

[0060] In a preferred embodiment, referring to Figure 5 The mounting ring 1 is provided with a plurality of avoidance notches 12, and the avoidance notches 12 are arranged one-to-one corresponding to the monochromatic light emitters 2, so that the monochromatic light emitters 2 can be closer to the central axis of the mounting ring 1, so as to further reduce the volume of the lighting auxiliary imaging device, and at the same time reduce the weight of the lighting auxiliary imaging device.

[0061] In a preferred embodiment, referring to Figure 1 The mounting ring 1 is provided with a support rod 13, and the CCD4 is arranged on the support rod 13, thereby realizing the integration of the CCD4 into the mounting ring 1, thereby reducing the number of assembly parts required when the lighting auxiliary imaging device is installed on other structures, so as to achieve the effect of facilitating the installation of the lighting auxiliary imaging device on other structures, and at the same time ensure that the CCD4 and the lens 3 are in a coaxial state with the mounting ring 1.

[0062] Further, see Figure 1The CCD4 is provided with a connecting bracket 41, which is sleeved on the supporting rod 13, and the connecting bracket 41 is threadedly connected with a locking rod that can be pressed against the supporting rod 13.

[0063] When adjusting CCD4, first twist the locking rod to separate the locking rod from the support rod 13, and then slide CCD4, so that CCD4 drives the connecting bracket 41 to move, and the connecting bracket 41 and the support rod 13 move relative to each other, so as to adjust the relative position of CCD4 and the mounting ring 1; after adjusting the position of CCD4, twist the locking rod in the opposite direction to make the locking rod press against the support rod 13, so that the locking rod and the support rod 13 are tightly matched to lock the connecting bracket 41, so as to complete the adjustment of CCD4. In the process of adjusting the position of CCD4, it is only necessary to twist the locking rod and slide CCD4, so as to achieve the effect of facilitating the adjustment of the position of CCD4.

[0064] In a preferred embodiment, referring to Figure 1 A plurality of mounting holes 14 are provided on the circumferential side of the mounting ring 1 for connecting the mounting ring 1 to an external structure. When the lighting auxiliary imaging device is subsequently mounted on the external structure, it is only necessary to extend the rod-shaped structure on the external structure into the mounting hole 14, so as to facilitate the installation of the lighting auxiliary imaging device on the external structure. At the same time, the provision of the plurality of mounting holes 14 increases the connection stability between the lighting auxiliary imaging device and the external structure.
