[0004] The above and the prior art have the following defects: During the use of the vision camera, since the vision camera is installed in a fixed position, it is difficult to adjust the orientation of the vision camera in a timely manner according to needs, resulting in the vision camera being difficult to accurately photograph the surface of the product, thereby reducing the practicability of the vision camera.

[0005] Therefore, a camera adjustment structure for machine vision is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the defect that since the vision camera is installed in a fixed position, it is difficult to adjust the orientation of the vision camera in a timely manner according to needs, resulting in the vision camera being difficult to accurately photograph the surface of the product, and to propose a camera adjustment structure for machine vision.

[0007] To achieve the above object, the present invention adopts the following technical solution: A camera adjustment structure for machine vision, including a CCD camera, on the surface of which an adapter plate is fixedly assembled. On the surface of the adapter plate, a sliding plate is rotatably connected. Inside the sliding plate, a truss is slidably connected. It further includes:

[0008] An adjustment device arranged on the surface of the sliding plate for adjusting the shooting orientation of the CCD camera. The adjustment device includes a fixed plate fixedly installed on the surface of the sliding plate, a gear and a rack for horizontally moving the CCD camera, and an adjustment plate for rotating the CCD camera.

[0009] A cleaning device arranged on the surface of the fixed plate for cleaning the surface of the rack. The cleaning device includes an extension plate fixedly installed on the surface of the fixed plate and a first brush wire for cleaning the rack.

[0010] An auxiliary device arranged on the surface of the fixed plate for reducing the wear of the first brush wire. The auxiliary device includes a rectangular block fixedly installed on the surface of the fixed plate, a top block and a round rod that cooperate to adjust the height of the first brush wire.

[0011] The effects achieved by the above components are as follows: By setting the adjustment device, during the use of the CCD camera, the position and angle of the CCD camera can be adjusted in time according to needs, enabling the CCD camera to be aligned with the area to be detected of the product, improving the practicability of the CCD camera. By setting the cleaning device, during the horizontal movement of the CCD camera, the first brush wire will clean the dust and other foreign objects attached to the surface of the rack, avoiding the situation where foreign objects interfere with the normal meshing of the gear and the rack. By setting the auxiliary device, during the cleaning of the tooth surface of the rack, through the cooperation of the round rod and the top block, while ensuring the normal cleaning of the rack, the wear of the first brush wire is reduced, and the service life of the first brush wire is extended.

[0012] Preferably, a rotating shaft is rotatably connected inside the fixed plate. The gear is fixedly installed on the circumferential surface of the rotating shaft. The rack is fixedly installed on the upper surface of the truss. The gear meshes with the rack. An electric push rod is fixedly assembled on the lower surface of the sliding plate. The adjustment plate is fixedly installed at the output end of the electric push rod. The adjustment plate abuts against the surface of the CCD camera.

[0013] The effects achieved by the above components are as follows: When it is necessary to adjust the horizontal position of the CCD camera, the servo motor is turned on. The output end of the servo motor drives the rotating shaft to rotate, and the rotating shaft drives the gear to rotate. Since the gear meshes with the rack, the rotation of the gear causes the sliding plate to slide horizontally along the truss, thereby driving the CCD camera to move horizontally, realizing the adjustment of the shooting horizontal position. When it is necessary to rotate and adjust the CCD camera, the electric push rod is started. The output end of the electric push rod extends or retracts, driving the adjustment plate to move. The adjustment plate pushes the CCD camera to rotate around the axis at the connection between the connection plate and the sliding plate. The two adjustment plates simultaneously abut against the surface of the CCD camera and can also fix the position of the CCD camera. Therefore, during the use of the CCD camera, the position and angle of the CCD camera can be adjusted in a timely manner according to needs.

[0014] Preferably, a fixed tube is fixedly assembled on the lower surface of the sliding plate. A sliding rod is slidably connected to the inner wall of the fixed tube, and the sliding rod is fixedly connected to the adjustment plate.

[0015] The effects achieved by the above components are as follows: The arrangement of the fixed tube and the sliding rod provides guidance and stable support for the movement of the adjustment plate, ensuring the smoothness of the rotation adjustment of the CCD camera.

[0016] Preferably, two positioning blocks are fixedly assembled on the surface of the CCD camera, and the two adjustment plates are located between the two positioning blocks.

[0017] The effects achieved by the above components are as follows: The positioning blocks play a role in restricting the rotation range of the CCD camera, thereby realizing the precise rotation adjustment of the shooting angle of the CCD camera.

[0018] Preferably, a connecting tube is slidably penetrated in the extension plate. A connecting block is snap-connected to the inner wall of the connecting tube. The lower surface of the connecting block is fixedly assembled with a mounting plate, and the first brush wire is fixedly installed on the lower surface of the mounting plate. One end of the mounting plate is in a triangular structure, and the connecting block is in a hexagonal prism structure.

[0019] The effects achieved by the above components are as follows: During the horizontal movement of the CCD camera, the sliding plate drives the fixed plate to move, the fixed plate drives the extension plate to move, the extension plate drives the connecting tube to move, the connecting block moves following the connecting tube and drives the mounting plate to move, the mounting plate drives the first brush wire to slide along the tooth surface of the rack, and the first brush wire cleans the dust and other foreign matters attached to the surface of the rack, avoiding the occurrence of foreign matters interfering with the normal meshing of the gear and the rack.

[0020] Preferably, a magnetic block is fixedly assembled on the inner wall of the connecting tube. The connecting block is made of iron and abuts against the surface of the magnetic block.

[0021] The effect achieved by the above components is that when the connecting block contacts the magnetic block, the magnetic block will attract the connecting block, thereby limiting the position of the connecting block, and further limiting the position of the first brush filament.

[0022] Preferably, a first spring is sleeved on the surface of the connecting pipe, and two ends of the first spring are fixedly connected to the connecting pipe and the extension plate respectively.

[0023] The effect achieved by the above components is that the first spring continues to contract, and the connecting tube will squeeze the mounting plate with the help of the elastic force of the first spring, thereby ensuring that the first brush wire can stably rest against the tooth surface of the rack.

[0025] The effect achieved by the above components is: in the process of cleaning the tooth surface of the rack, the rotation of the shaft will drive the paddle to rotate, the paddle will squeeze the transmission plate, the transmission plate will drive the strip plate to move, at this time the sliding directions of the strip plate and the slide plate are opposite, the movement of the strip plate will drive the top block to move, the top block will squeeze the round rod, the round rod will drive the connecting tube to move upward, with the cooperation of the magnetic block, the connecting block will drive the mounting plate to move upward, so that the first brush wire is out of contact with the rack, so in the process of the CCD camera moving in the horizontal direction, only one first brush wire on the mounting plate will clean the rack, thereby reducing the wear of the first brush wire.

[0026] Preferably, the vertical cross-section of the top block is triangular.

[0027] The effect achieved by the above components is that the inclined surface of the top block with a triangular vertical section can squeeze the round rod to move the round rod upward.

[0028] Preferably, a support plate is fixedly mounted on the surface of the fixed plate, a square plate is fixedly mounted on the surface of the strip plate, and a second spring is fixedly mounted between the support plate and the square plate.

[0029] The effect achieved by the above components is that the second spring can reset the strip plate by means of its own elastic force.

[0045] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0046] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0047] Embodiment 1:

[0048] As Figures 1 - 8 shown, the present invention provides a camera adjustment structure for machine vision, including a CCD camera 1, a connecting plate 2 fixedly assembled on the surface of the CCD camera 1, a slide plate 3 rotatably connected to the surface of the connecting plate 2, and a truss 4 slidably connected to the inner wall of the slide plate 3. It also includes: an adjusting device 5 arranged on the surface of the slide plate 3 for adjusting the shooting orientation of the CCD camera 1, and the adjusting device 5 includes a fixed plate 501 fixedly installed on the surface of the slide plate 3, a gear 503 and a rack 504 for horizontally moving the CCD camera 1, and an adjusting plate 506 for rotating the CCD camera 1; a cleaning device 6 arranged on the surface of the fixed plate 501 for cleaning the surface of the rack 504, and the cleaning device 6 includes an extension plate 61 fixedly installed on the surface of the fixed plate 501 and a first brush wire 65 for cleaning the rack 504; an auxiliary device 7 arranged on the surface of the fixed plate 501 for reducing the wear of the first brush wire 65, and the auxiliary device 7 includes a rectangular block 71 fixedly installed on the surface of the fixed plate 501, a top block 73 and a round bar 74 that cooperate with each other to adjust the height of the first brush wire 65.

[0049] As Figures 2 - 5As shown, a rotating shaft 510 is rotatably connected inside the fixing plate 501. A servo motor 502 is fixedly assembled on the surface of the fixing plate 501. The output end of the servo motor 502 is fixedly connected to the rotating shaft 510. A gear 503 is fixedly installed on the circumferential surface of the rotating shaft 510. A rack 504 is fixedly installed on the upper surface of the truss 4. The gear 503 meshes with the rack 504. An electric push rod 505 is fixedly assembled on the lower surface of the sliding plate 3. An adjusting plate 506 is fixedly installed at the output end of the electric push rod 505. The adjusting plate 506 abuts against the surface of the CCD camera 1. When it is necessary to adjust the horizontal position of the CCD camera 1, the servo motor 502 is turned on. The output end of the servo motor 502 will drive the rotating shaft 510 to rotate. The rotating shaft 510 drives the gear 503 to rotate. Since the gear 503 meshes with the rack 504, the rotation of the gear 503 will cause the sliding plate 3 to slide horizontally along the truss 4, thereby driving the CCD camera 1 to move horizontally, realizing the adjustment of the shooting horizontal position. When it is necessary to perform rotational adjustment on the CCD camera 1, the electric push rod 505 is started. The output end of the electric push rod 505 extends or retracts, driving the adjusting plate 506 to move. The adjusting plate 506 will push the CCD camera 1 to rotate around the axis at the connection between the connecting plate 2 and the sliding plate 3. The two adjusting plates 506 simultaneously abut against the surface of the CCD camera 1 and can also fix the position of the CCD camera 1. Therefore, during the use of the CCD camera 1, the position and angle of the CCD camera 1 can be adjusted in a timely manner according to needs. A fixed tube 507 is fixedly assembled on the lower surface of the sliding plate 3. A sliding rod 508 is slidably connected to the inner wall of the fixed tube 507. The sliding rod 508 is fixedly connected to the adjusting plate 506. The settings of the fixed tube 507 and the sliding rod 508 provide guidance and stable support for the movement of the adjusting plate 506, ensuring the smoothness of the rotational adjustment of the CCD camera 1. Two positioning blocks 509 are fixedly assembled on the surface of the CCD camera 1. The two adjusting plates 506 are located between the two positioning blocks 509. The positioning blocks 509 play a role in restricting the rotation range of the CCD camera 1, thereby realizing the precise rotational adjustment of the shooting angle of the CCD camera 1.

[0050] As Figure 2 and Figure 6 as well as Figure 7As shown, a connecting pipe 62 slides through the extension plate 61. A connecting block 63 is snap-fitted to the inner wall of the connecting pipe 62. An installation plate 64 is fixedly assembled to the lower surface of the connecting block 63. The first brush filaments 65 are fixedly installed on the lower surface of the installation plate 64. One end of the installation plate 64 is triangular in structure, and the connecting block 63 is hexagonal prism-shaped. During the horizontal movement of the CCD camera 1, the sliding plate 3 drives the fixed plate 501 to move. The fixed plate 501 drives the extension plate 61 to move. The extension plate 61 drives the connecting pipe 62 to move. The connecting block 63 moves along with the connecting pipe 62 and drives the installation plate 64 to move. The installation plate 64 drives the first brush filaments 65 to slide along the tooth surface of the rack 504. The first brush filaments 65 clean dust and other foreign objects adhering to the surface of the rack 504, avoiding the occurrence of foreign objects interfering with the normal meshing of the gear 503 and the rack 504. A magnetic block 66 is fixedly assembled to the inner wall of the connecting pipe 62. The connecting block 63 is made of iron and abuts against the surface of the magnetic block 66. When the connecting block 63 contacts the magnetic block 66, the magnetic block 66 attracts the connecting block 63, thereby restricting the position of the connecting block 63 and further restricting the position of the first brush filaments 65. A first spring 67 is sleeved on the surface of the connecting pipe 62. The two ends of the first spring 67 are fixedly connected to the connecting pipe 62 and the extension plate 61 respectively. As the first spring 67 continuously contracts, the connecting pipe 62 presses the installation plate 64 by means of the elastic force of the first spring 67, ensuring that the first brush filaments 65 can stably abut against the tooth surface of the rack 504.

[0051] As Figure 5 and Figure 8As shown, a strip plate 72 slides through a rectangular block 71. A top block 73 is fixedly installed on the surface of the strip plate 72. A round rod 74 is fixedly installed on the outer wall of a connecting pipe 62. A plurality of paddles 78 are fixedly assembled on the circumferential surface of a rotating shaft 510. A transmission piece 79 is fixedly assembled at the position of the strip plate 72 relative to the paddle 78. During the process of cleaning the tooth surface of a rack 504, the rotation of the rotating shaft 510 will drive the paddle 78 to rotate. The paddle 78 will squeeze the transmission piece 79. The transmission piece 79 will drive the strip plate 72 to move. At this time, the sliding direction of the strip plate 72 is opposite to that of a sliding plate 3. The movement of the strip plate 72 will drive the top block 73 to move. The top block 73 will squeeze the round rod 74. The round rod 74 will drive the connecting pipe 62 to move upward. With the cooperation of a magnetic block 66, a connecting block 63 will drive a mounting plate 64 to move upward, so that a first brush wire 65 is separated from the rack 504. Therefore, during the process of the CCD camera 1 moving horizontally, only the first brush wire 65 on one mounting plate 64 will clean the rack 504, thus reducing the wear of the first brush wire 65. The vertical section of the top block 73 is triangular. The inclined surface of the top block 73 with a triangular vertical section can squeeze the round rod 74 to make the round rod 74 move upward. A support plate 75 is fixedly assembled on the surface of a fixing plate 501. A square plate 76 is fixedly assembled on the surface of the strip plate 72. A second spring 77 is fixedly assembled between the support plate 75 and the square plate 76. The second spring 77 can make the strip plate 72 reset by means of its own elastic force.

[0052] The overall working principle is that when it is necessary to adjust the horizontal position of the CCD camera 1, the servo motor 502 is turned on. The output end of the servo motor 502 will drive the rotating shaft 510 to rotate. The rotating shaft 510 drives the gear 503 to rotate. Since the gear 503 meshes with the rack 504, the rotation of the gear 503 will make the sliding plate 3 slide horizontally along the truss 4, thereby driving the CCD camera 1 to move horizontally to realize the adjustment of the shooting horizontal position. When it is necessary to rotate and adjust the CCD camera 1, the electric push rod 505 is started. The output end of the electric push rod 505 extends or retracts to drive an adjusting plate 506 to move. The adjusting plate 506 will push the CCD camera 1 to rotate around the axis at the connection of the connecting plate 2 and the sliding plate 3. The two adjusting plates 506 are simultaneously abutted against the surface of the CCD camera 1 and can also fix the position of the CCD camera 1. Therefore, during the use of the CCD camera 1, the position and angle of the CCD camera 1 can be adjusted in time according to needs, so that the CCD camera 1 can be aligned with the part to be detected of the product, improving the practicability of the CCD camera 1. The positioning block 509 plays a role in limiting the rotation range of the CCD camera 1, so as to realize the precise rotation adjustment of the shooting angle of the CCD camera 1. The setting of the fixed pipe 507 and the sliding rod 508 provides guidance and stable support for the movement of the adjusting plate 506, ensuring the smoothness of the rotation adjustment of the CCD camera 1.

[0053] During the horizontal movement of the CCD camera 1, the skateboard 3 drives the fixed plate 501 to move, the fixed plate 501 drives the extension plate 61 to move, the extension plate 61 drives the connecting pipe 62 to move, and the connecting block 63 follows the movement of the connecting pipe 62 to drive the mounting plate 64 to move. The mounting plate 64 drives the first brush wire 65 to slide along the tooth surface of the rack 504. The first brush wire 65 cleans the dust and other foreign objects attached to the surface of the rack 504, avoiding the interference of foreign objects with the normal meshing of the gear 503 and the rack 504. During this process, the first spring 67 continuously contracts, and the connecting pipe 62 squeezes the mounting plate 64 by means of the elastic force of the first spring 67, so as to ensure that the first brush wire 65 can stably abut against the tooth surface of the rack 504. At the same time, since one end of the mounting plate 64 is triangular in structure, the distribution of the first brush wire 65 on the surface of the mounting plate 64 will be restricted. During the movement of the first brush wire 65, foreign objects will be pushed from the middle of the rack 504 to both sides of the rack 504, thus improving the cleaning effect. The connecting block 63 in the shape of a regular hexagonal prism can limit the movement path of the mounting plate 64, so that the first brush wire 65 is aligned with the rack 504. When the first brush wire 65 needs to be replaced, pull up the connecting pipe 62, then move the mounting plate 64 to pull out the connecting block 63 from the connecting pipe 62, remove the old first brush wire 65, and then move the mounting plate 64 with the new first brush wire 65 so that the connecting block 63 is inserted into the connecting pipe 62. When the connecting block 63 contacts the magnetic block 66, the magnetic block 66 will attract the connecting block 63, thereby restricting the position of the connecting block 63 and further restricting the position of the first brush wire 65. Then release the connecting pipe 62, and the first brush wire 65 will abut against the tooth surface of the rack 504.

[0054] During the process of cleaning the tooth surface of the rack 504, the rotation of the rotating shaft 510 will drive the paddle 78 to rotate. The paddle 78 will squeeze the transmission piece 79, and the transmission piece 79 will drive the strip plate 72 to move. At this time, the sliding direction of the strip plate 72 is opposite to that of the sliding plate 3. The movement of the strip plate 72 will drive the top block 73 to move. The inclined surface of the top block 73 with a triangular vertical cross-section will squeeze the round rod 74, and the round rod 74 will drive the connecting pipe 62 to move upward. With the cooperation of the magnetic block 66, the connecting block 63 will drive the mounting plate 64 to move upward, so that the first brush wire 65 is separated from the rack 504. Therefore, during the horizontal movement of the CCD camera 1, only the first brush wire 65 on one mounting plate 64 will clean the rack 504, thus reducing the wear of the first brush wire 65. The movement of the strip plate 72 will drive the square plate 76 to move. At this time, the second spring 77 will be stretched or compressed. The paddle 78 will continue to rotate and disengage from the transmission piece 79, and then the next paddle 78 will quickly abut against the surface of the transmission piece 79 to prevent the transmission piece 79 from resetting, so as to ensure that the first brush wire 65 is separated from the rack 504. When the output end of the servo motor 502 rotates in the reverse direction, the second spring 77 will use its own elastic force to reset the strip plate 72. With the cooperation of the paddle 78 and the transmission piece 79, the first brush wire 65 that did not originally contact the rack 504 will abut against the tooth surface of the rack 504, and the first brush wire 65 abutting against the tooth surface of the rack 504 will be separated from the rack 504. Therefore, while ensuring the normal cleaning of the rack 504, the wear of the first brush wire 65 is reduced, and the service life of the first brush wire 65 is extended.

[0055] Embodiment 2:

[0056] As Figures 1 - 10 shown, this embodiment further illustrates Embodiment 1. A moving component 68 is provided on the lower surface of the mounting plate 64. The moving component 68 includes a ball rod 681 rotatably mounted on the lower surface of the mounting plate 64. The lower end of the ball rod 681 is rotatably connected to a rigid plate 682. A plurality of second brush wires 683 are fixedly assembled on the lower surface of the rigid plate 682. A third spring 684 is fixedly assembled between the rigid plate 682 and the mounting plate 64. The third spring 684 is always in a compressed state. During the process of cleaning the rack 504, with the cooperation of the ball rod 681 and the third spring 684, the reaction force generated when the second brush wire 683 moves along the surface of the rack 504 will cause the rigid plate 682 to move irregularly relative to the mounting plate 64, and then the second brush wire 683 will move irregularly, further improving the cleaning effect of the second brush wire 683.

[0057] Embodiment 3:

[0058] In comparison with the second embodiment of the present application, the end part of the second brush wire 683 movably penetrates through the hard board 682 and is fixedly connected to the mounting plate 64. When the hard board 682 moves under the action of the cue 681 and the third spring 684, the hard board 682 moves relative to the second brush wire 683, avoiding the accumulation of impurities at the junction between the second brush wire 683 and the hard board 682.

[0059] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
