Description

Technical Field

[0001] The utility model relates to the technical field of fixing parts of a CCD photographing mechanism, in particular to an installation and fixing structure of a CCD photographing mechanism. Background Art

[0002] A CCD photographing mechanism is a device that uses a CCD image sensor to capture images. The CCD photographing mechanism is widely used in industrial inspection, medical imaging and other fields. The CCD photographing mechanism captures images of parts on a conveyor belt assembly line, and then a computer detects the parts according to the images of the CCD photographing mechanism.

[0003] The CCD photographing mechanism is fixed above the conveyor belt assembly line through a lifting mechanism. The CCD photographing mechanism adjusts the distance from the conveyor belt assembly line along with the lifting mechanism. The CCD photographing mechanism and the lifting mechanism are directly fixed by bolts. During the lifting process of the CCD photographing mechanism along with the lifting mechanism, the lifting angle of the CCD photographing mechanism will also change. The CCD photographing mechanism uses an L-shaped connecting frame to perform horizontal and vertical direction conversions with the lifting mechanism. If the angle is still not appropriate, it is necessary to bend the L-shaped connecting frame to further adjust the inclination of the CCD photographing mechanism, which is very inconvenient to use. Summary of the Invention

[0004] The embodiment of the present disclosure relates to an installation and fixing structure of a CCD photographing mechanism. While the first fixing frame is fixed to the CCD photographing mechanism by bolts, the side fixing frame and the tail limiting convex block clamp and fix both sides of the CCD photographing mechanism. With double fixing, the fixing of the CCD photographing mechanism is more firm and stable. The worm rod member meshes with and drives the worm wheel member to rotate, and the first fixing frame and the CCD photographing mechanism are adjusted for the inclination angle, so that the CCD photographing mechanism is adjusted to a suitable photographing direction, ensuring the stability of the CCD photographing and imaging quality.

[0005] In the first aspect of the present disclosure, there is provided an installation and fixing structure of a CCD photographing mechanism, which specifically includes: a first fixing frame, a second fixing frame and a side fixing frame. The second fixing frame is arranged at the rear of the first fixing frame, and side fixing frames are arranged on both sides of the front part of the first fixing frame. A first bolt through hole is formed through the middle of the first fixing frame. Side sliding frames are fixed on both sides of the first fixing frame. A middle screw tube is fixed on the outer side of the side sliding frame. A lower connecting block is fixed at the lower part of the first fixing frame. A connecting rotating shaft is fixed at the tail of the lower connecting block, and a worm wheel member is fixed at the head of the connecting rotating shaft.

[0006] Further, a middle screw rod is rotatably arranged on the outer side of the side fixing frame, and tail limiting convex blocks protrude inwards from both the upper and lower parts of the head of the side fixing frame.

[0007] Furthermore, the side fixing bracket is of an H-shaped structure, and the side fixing bracket is slidably connected downward with the side sliding bracket. The middle screw rod and the middle screw tube are penetrated and screwed, and the middle screw rod moves axially while rotating axially along the thread of the middle screw tube.

[0008] Furthermore, a second bolt through hole is penetrated through the middle of the second fixing bracket, and a worm member is rotated on one side of the lower part of the second fixing bracket.

[0009] Furthermore, the lower part of the second fixing bracket is rotatably connected through the connecting rotating shaft, the worm member is meshed and connected with the worm gear member, and the worm member meshes and drives the worm gear member to rotate.

[0010] Furthermore, when the worm member meshes and rotates the worm gear member, the first fixing bracket rotates around the connecting rotating shaft as the center, and the first fixing bracket and the CCD photographing mechanism adjust the tilting angle.

[0011] Furthermore, the middle screw rod moves axially while rotating circumferentially along the middle screw tube. The side fixing bracket moves synchronously along the side sliding bracket. The middle screw tube, the side fixing bracket and the tail limiting convex block move synchronously. The tail limiting convex block moves closer to the first fixing bracket. The tail limiting convex block and the first fixing bracket clamp on both opposite sides of the CCD photographing mechanism, and the side fixing bracket and the tail limiting convex block clamp and fix the CCD photographing mechanism.

[0012] The present utility model provides an installation and fixing structure for a CCD photographing mechanism, which has the following beneficial effects:

[0013] While the first fixing bracket and the CCD photographing mechanism are fixed by bolts, the side fixing bracket and the tail limiting convex block clamp and fix both sides of the CCD photographing mechanism. With double fixing, the fixing of the CCD photographing mechanism is more firm and stable.

[0014] The worm member meshes and drives the worm gear member to rotate, and the first fixing bracket and the CCD photographing mechanism adjust the tilting angle, so that the CCD photographing mechanism is adjusted to a proper photographing direction, ensuring the stability of the CCD photographing imaging quality.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0029] Embodiment 1: Please refer to Figures 1 to 6 :

[0030] The present utility model provides a mounting and fixing structure for a CCD photographing mechanism, including: a first fixing frame 1, a second fixing frame 2, and a side fixing frame 3. A first bolt through-hole 101 is provided through the middle of the first fixing frame 1. The first bolt through-hole 101 is an elliptical structure, and the elliptical first bolt through-hole 101 can adapt to bolt hole positions with different width intervals. Side sliding frames 102 are fixed on both sides of the first fixing frame 1. A middle screw tube 103 is fixed on the outer side of the side sliding frame 102. A lower connecting block 104 is fixed at the lower part of the first fixing frame 1. A connecting rotating shaft 105 is fixed at the tail of the lower connecting block 104. A worm gear member 106 is fixed at the head of the connecting rotating shaft 105. A second fixing frame 2 is arranged at the rear of the first fixing frame 1. A second bolt through-hole 201 is provided through the middle of the second fixing frame 2. The second bolt through-hole 201 is an elliptical structure, and the elliptical second bolt through-hole 201 can adapt to bolt hole positions with different width intervals. A worm rod member 202 is rotatably arranged at one side of the lower part of the second fixing frame 2. The lower part of the second fixing frame 2 and the connecting rotating shaft 105 are rotatably connected through. The spiral teeth outside the worm rod member 202 are meshed and connected with the tooth blocks arrayed outside the worm gear member 106. The meshing of the worm rod member 202 drives the worm gear member 106 to rotate. Side fixing frames 3 are arranged on both sides of the front part of the first fixing frame 1. A middle screw rod 301 is rotatably arranged on the outer side of the side fixing frame 3. Tail limiting protrusions 302 protrude inwards from both the upper and lower parts of the head of the side fixing frame 3. The side fixing frame 3 is an H-shaped structure. The side fixing frame 3 is slidably connected with the side sliding frame 102 in the downward direction. The middle screw rod 301 and the middle screw tube 103 are screwed through. The middle screw rod 301 moves axially while rotating axially along the thread of the middle screw tube 103.

[0031] In the embodiments of the present disclosure, as Figure 2 , 3 , as shown in FIGS. 4, when the worm rod member 202 meshes with the worm gear member 106 to rotate, the first fixing frame 1 rotates around the connecting rotating shaft 105 as the center. The inclination angle of the first fixing frame 1 and the CCD photographing mechanism is adjusted. The first fixing frame 1 and the CCD photographing machine are adjusted for conversion in different directions such as horizontal and vertical. The CCD photographing mechanism is adjusted to a suitable photographing angle. The CCD photographing mechanism adjusts the angle according to the change in height. The CCD photographing mechanism ensures that the photographing component is in the centered position, improving the recognition efficiency of the photographed image.

[0032] In the embodiments of the present disclosure, as Figure 1 , 2As shown in FIGS. 4, the middle screw rod 301 rotates circumferentially along the middle screw tube 103 while moving axially. The side fixing frame 3 moves synchronously along the side sliding frame 102. The middle screw tube 103, the side fixing frame 3 and the tail limiting convex block 302 move synchronously. The tail limiting convex block 302 moves closer to the first fixing frame 1. The tail limiting convex block 302 and the first fixing frame 1 clamp on both opposite sides of the CCD photographing mechanism. The side fixing frame 3 and the tail limiting convex block 302 clamp and fix the CCD photographing mechanism. After the CCD photographing mechanism is positioned, there is no need for manual fixing operation. The CCD photographing mechanism is directly installed and fixed through the first bolt through hole 101. The bolt hole alignment installation of the CCD photographing mechanism and the first fixing frame 1 is faster.

[0033] Embodiment 2: On the basis of Embodiment 1, rubber layers are provided on the contact surfaces of the first fixing frame 1, the side fixing frame 3, the tail limiting convex block 302 and the CCD photographing mechanism. The first fixing frame 1, the side fixing frame 3 and the tail limiting convex block 302 are in contact with the CCD photographing mechanism through the rubber layers. The rubber layers play a role in moving buffering and improve the stability of the CCD photographing mechanism.

[0034] The working principle of this Embodiment 1: The CCD photographing mechanism is a device that uses a CCD image sensor to capture images. The middle part of the CCD photographing mechanism is a rectangular block-shaped connection structure. The first bolt through hole 101 is screwed and fixed to the threaded hole of the CCD photographing mechanism through a bolt, realizing the bolt fixation of the first fixing frame 1 and the CCD photographing mechanism. The middle screw rod 301 rotates, and the middle screw rod 301 moves axially along the middle screw tube 103. The middle screw tube 103, the side fixing frame 3 and the tail limiting convex block 302 move synchronously. The tail limiting convex block 302 moves closer to the first fixing frame 1. The tail limiting convex block 302 and the first fixing frame 1 clamp on both opposite sides of the CCD photographing mechanism. The side fixing frame 3 and the tail limiting convex block 302 clamp and fix the CCD photographing mechanism. With the double fixation of bolts and clamping, the fixation of the CCD photographing mechanism is more firm and stable. The clamping of the first fixing frame 1 and the first fixing frame 1 on the CCD photographing mechanism can also perform the positioning operation before the bolt fixation of the CCD photographing mechanism. After the CCD photographing mechanism is positioned, there is no need for manual alignment of the first bolt through hole 101, which is convenient for the bolt hole alignment installation operation of the CCD photographing mechanism;

[0035] The second fixing frame 2 is bolt-fixed to the lifting frame through the second bolt through-hole 201. Driven by the lifting frame, the second fixing frame 2, the first fixing frame 1, and the CCD photographing mechanism move to adjust the height and the photographing range. The worm rod member 202 meshes with and drives the worm wheel member 106 to rotate. The worm wheel member 106, the connecting rotating shaft 105, the lower connecting block 104, and the first fixing frame 1 rotate synchronously around the connecting rotating shaft 105 as the center. The first fixing frame 1 and the CCD photographing mechanism adjust the tilt angle. The first fixing frame 1 and the CCD camera perform conversion adjustments in different directions such as horizontal and vertical. The CCD photographing mechanism is adjusted to a suitable photographing direction to ensure that the photographed component is in the centered position, ensuring the stability of the CCD photographing imaging quality, improving the recognition efficiency of the photographed image, eliminating the operation of further adjusting the tilt of the CCD photographing mechanism by bending the L-shaped connecting frame, and making the angle adjustment of the CCD photographing mechanism more convenient.
