Description

Technical Field

[0001] The present invention relates to the technical field of optical image detectors, and in particular to an optical image detector for industrial camera detection and a method for using the same. Background Art

[0002] Optical image detector is a device that uses optical principles and technologies to measure and analyze the surface of objects. In industrial production, the industrial camera on the optical image detector and the workbench for holding materials are often used to measure products.

[0003] When some existing optical image detectors use industrial cameras for shooting and inspection, it is necessary to place the product on a workbench and move the workbench under the industrial camera for measurement. However, due to long-term use, stains (such as oil and dust) are prone to appear on the workbench and industrial camera. If these stains remain in key positions such as the industrial camera lens and the material placement table on the optical image detector, the industrial camera used for measurement will be affected by the stains during the measurement process, resulting in a reduction in accuracy, which needs to be improved. Summary of the invention

[0004] The object of the present invention is to provide an optical image detector for industrial camera detection and a method of using the same to solve the problems raised in the above-mentioned background technology.

[0007] Two fixing plates are provided and both are arranged on the mounting frame, and the fixing plates are used to position and install the material placement table;

[0008] A guide plate is arranged between the two fixed plates, and the guide plate is connected to the material placement table through a connecting shaft, so as to facilitate the control of the rotation of the material placement table to unload materials and reduce the contact between the staff and the material placement table when taking the product;

[0009] A protective cover is arranged on the periphery of the industrial camera to provide protection for the industrial camera;

[0010] A protective plate, used to cooperate with the protective cover to provide protection for the lens part of the industrial camera;

[0011] A fitting plate, used to guide the protective plate to move its position and to use the industrial camera;

[0012] A slide plate, provided on the protective cover, for autonomous movement when the industrial camera is used;

[0013] A limit assembly is provided on the slide plate, and is used to guide the movement of the bonding plate during the use of the industrial camera to avoid obstructing the use of the industrial camera;

[0014] The position of the material placement table is adjusted by sliding on the fixed plate, and the material placement table is tilted by rotating the connecting shaft, so that the product slides down autonomously, thereby preventing the material placement table from being stained when the product is taken out;

[0015] The protective plate and the protective cover cooperate to form a cover body, which provides protection for the industrial camera to prevent it from being stained.

[0016] Two support frames are connected to the material loading platform, and guide plates are connected to the two support frames. The support frames are used to enable the guide plates to move synchronously with the material loading platform. A cross plate is connected to the guide plate, and a rotating shaft is arranged on the cross plate. A connecting plate is connected to the rotating shaft, and an arc-shaped cover plate is arranged on one side of the connecting plate. Two extension plates are arranged on the arc-shaped cover plate, and a guide groove is arranged on the arc-shaped cover plate. A sliding block is slidably installed in the guide groove, and the sliding block is connected to the inner wall of the guide groove by a connecting spring, and the sliding block is connected to the connecting plate as a whole. The two arc-shaped cover plates can provide shielding protection for the material loading platform for holding products during the detection process.

[0017] Two translational slide grooves are provided at the bottom end of the protective cover, and the translational slide grooves are adapted to the size of the slide plate, and the two slide plates are respectively located in the two translational slide grooves, and the translational slide grooves are each provided with a return spring, and the return spring can facilitate the sliding plate to be pushed out of the translational slide groove, and four movable slide grooves are also provided at the bottom end of the protective cover, and the movable slide grooves are each slidably installed with a slider, and the four sliders are respectively connected to one of the fitting plates, and the slider and the inner wall of the movable slide groove are connected by a docking spring, and the docking spring can facilitate the pulling of the protective plate to move and adjust the position.

[0018] The protective cover is connected to a limit baffle, and an inclined portion is provided on the limit baffle.

[0026] Step 2: As the guide plate moves, the slide plate will move along its surface, allowing the protective plate to be moved away from directly under the industrial camera, allowing product inspection to begin.

[0027] Step 3: After the inspection is completed, pull the loading table to move. At this time, the arc cover plate is rotated upward by rotating the shaft, and the four protective plates are contracted by the reset spring to provide protection for the bottom of the industrial camera again. When the loading table moves to the position where it is disconnected from the fixed plate, the loading table can be rotated by connecting the rotating shaft to make the product on the loading table slide off, avoiding stains on the loading table when the staff takes the product.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention controls the material placement table to rotate downward through the connecting shaft, so that the products to be tested on the material placement table slide down autonomously, thereby preventing the staff from directly taking the products on the material placement table with their hands, causing stains on the material placement table.

[0030] By pushing the sliding plate to move through the L-shaped limit plate, the touch plate on the sliding plate pushes the bonding plate to move, so that the four protective plates installed on the bonding plate can shield and protect the lens part of the industrial camera, thereby preventing the lens part of the industrial camera from being stained when the industrial camera is not in use.

[0031] By moving two arc cover plates and two extension plates to the top of the material placement table, it is possible to provide light shielding protection for the products located on the top of the material placement table during the inspection process, and avoid placing other products on the material placement table during the inspection process, which would cause confusion in the inspection information.

The slider is placed into the slide groove, and the slider slides in the slide groove to ensure that the guide plate 5 and the loading platform 1 can make a translational movement between the two fixed plates 4. An L-shaped positioning frame 3 is arranged on the mounting frame 2. After the guide plate 5 slides and fits the L-shaped positioning frame 3, it is prompted that the guide plate 5 and the loading platform 1 are installed in place. After the inspection is completed, the loading platform 1 is pulled to move. When the loading platform 1 moves to completely break the contact with the fixed plate 4, the loading platform 1 can be controlled to rotate downward through the connecting shaft 6, so that the product being inspected on the loading platform 1 can slide down autonomously, so as to prevent the staff from directly taking the product on the loading platform 1 with their hands, causing stains on the loading platform 1.

[0045] Two support frames 7 are fixedly installed on the top of the material loading platform 1, and guide plates 8 are fixedly installed on the tops of the two support frames 7. A cross plate 10 is fixedly installed on the two guide plates 8, and through holes are provided on the two cross plates 10, and a rotating shaft 11 is rotatably installed in the through hole. The rotating shaft 11 is connected to the inner wall of the through hole on the cross plate 10 by a torsion spring so that it can rotate independently. A connecting plate 12 is fixedly connected to the outer wall of the rotating shaft 11, and a baffle is provided on the side wall of the cross plate 10 close to the connecting plate 12. The baffle can prevent the torsion spring from controlling the connecting plate 12 to rotate excessively, resulting in the connecting plate 12 being unable to move to the bottom of the protective cover 18 under the guidance of the inclined part on the limit baffle 20. A sliding block 16 is fixedly installed on the side of the connecting plate 12 away from the rotating shaft 11. Two arc-shaped cover plates 13 are movably placed on the top of the material loading platform 1, and guide grooves 15 are provided on the two arc-shaped cover plates 13, and two guide grooves 15 are provided on the two arc-shaped cover plates 13.

The two sliding blocks 16 extend into the two guide slots 15 respectively, and connecting springs 17 are provided in the guide slots 15, and the two ends of the connecting springs 17 are respectively connected to the inner wall of the top of the guide slot 15 and the top of the sliding block 16. Two openings are provided on the side where the two arc-shaped cover plates 13 are close to each other, and extension plates 14 are movably installed in the openings. The extension plates 14 are made of rubber plates, and the extension plates 14 are connected to the inner walls of the openings on the arc-shaped cover plates 13 through springs, which can facilitate pushing the extension plates 14 out of the open inner cavity on the arc-shaped cover plates 13, and move to the top of the loading platform 1 through the two arc-shaped cover plates 13 and the two extension plates 14, so as to provide light shielding protection for the products at the top of the loading platform 1 during the detection process, and avoid placing other products on the loading platform 1 during the detection process, which causes confusion in the detection information.

[0046] An industrial camera 19 is installed on the mounting frame 2, and a fill light is provided at the bottom end of the industrial camera 19 to facilitate fill light during the detection process and to facilitate detection. A controller and an information processor are provided on the mounting frame 2, and the information processor and the controller are connected to the industrial camera 19 through lines to facilitate product detection. A protective cover 18 is installed on the outer wall of the industrial camera 19, and a limit baffle 20 is fixedly installed on the outer wall of the protective cover 18, and an inclined portion is provided on the limit baffle 20. When the guide plate 5 and the material placement table 1 are moved between the two fixed plates 4, the arc cover plate 13 will contact the inclined portion on the limit baffle 20 during the movement, and under the guidance of the inclined portion, the arc cover plate 13 will affect the rotating shaft 11, so that the rotating shaft 11 rotates and drives the arc cover plate 13 to rotate downward and is located at the top of the material placement table 1, and two translation slides 21 are provided at the bottom end of the protective cover 18, and slide plates 22 are slidably installed in the two translation slides 21, and a rubber is fixedly installed on the side wall of the side where the slide plate 22 extends out of the translation slide 21 The slide plate 22 has a certain elasticity, and the slide plate 22 is connected to the inner wall of the translational slide groove 21 by a return spring 23, and the slide plate 22 can be pulled into the translational slide groove 21 by the return spring 23. The bottom end of the slide plate 22 is fixedly installed with a limit assembly 24, and the limit assembly 24 includes a touch plate 28, and the touch plate 28 is fixedly installed on the slide plate 22. Two fixed rods 29 are fixedly installed on the touch plate 28. The two fixed rods 29 are both hollow cylinders and have holes on one side of the side wall. The inner cavity of the fixed rod 29 is A telescopic rod 30 is movably installed, and one side of the telescopic rod 30 extends out of the inner cavity of the fixed rod 29 through the hole on the fixed rod 29, and the side wall of the telescopic rod 30 that does not extend out of the inner cavity of the fixed rod 29 is connected to the inner wall of the fixed rod 29 through a spring, which ensures that the telescopic rod 30 can provide a limiting effect on the bonding plate 26 during the movement, and an anti-slip plate is fixedly installed on the telescopic rod 30, which contacts the bonding plate 26 through the anti-slip plate to prevent the bonding plate 26 from being separated from the telescopic rod 30 during the movement.

[0047] Four movable slots 25 are also provided at the bottom end of the protective cover 18, and sliders are slidably installed in the four movable slots 25, and a bonding plate 26 is fixedly installed on the slider, and the slider is connected to the inner wall of the movable slot 25 by a docking spring 34. The two ends of the bonding plate 26 are made of rubber to prevent the two ends of the bonding plate 26 from being at the angle between the touch plate 28 and the telescopic rod 30 during the movement of the bonding plate 26, because the bonding plate 26 cannot continue to move due to its hard texture. Protective plates 27 are fixedly installed on the four bonding plates 26. During use, the slide plate 22 is moved into the translation slot 21, so that the touch plate 28 and the telescopic rod 30 on the slide plate 22 push the bonding plate 26 to move toward the bottom center position of the protective cover 18. When the four protective plates 27 are assembled together, they can provide shielding protection for the industrial camera 19 to prevent the lens of the industrial camera 19 from being stained when the industrial camera 19 is not in use.

[0048] Two U-shaped blocks 31 are fixedly installed on the mounting frame 2, and a rotating rod 32 is rotatably installed on each of the two U-shaped blocks 31. An L-shaped limit plate 33 is fixedly installed on the outer wall of the rotating rod 32. The rotating rod 32 is connected to the U-shaped block 31 through a torsion spring. The torsion spring can be used to control the L-shaped limit plate 33 on the rotating rod 32 to rotate downward and fit the slide plate 22. The torsion spring used to connect the rotating rod 32 to the U-shaped block 31 generates a greater torsion force than the sum of the thrusts generated by the docking spring 34 and the return spring 23, thereby avoiding the L-shaped The limiting plate 33 cannot push the slide plate 22 into the translational slide groove 21, so after the loading table 1 is pulled out from between the two fixed plates 4, the guide plate 8 lacks restriction on the slide plate 22. The L-shaped limiting plate 33 rotates downward and contacts the slide plate 22, so that the slide plate 22 can be pushed to move into the translational slide groove 21. When the four protective plates 27 are assembled together, the slide plate 22 and the L-shaped limiting plate 33 will stop moving, which is convenient for providing protection for the lens part of the industrial camera 19 when the industrial camera 19 is not in use.

[0049] A pry plate 9 is installed on the guide plate 8, and an inclined surface and a placement groove are provided on the guide plate 8. When the material placement table 1 moves horizontally between the two fixed plates 4, the L-shaped limit plate 33 and the slide plate 22 are in a fitted state. The pry plate 9 will contact the L-shaped limit plate 33 in the process of following the movement of the guide plate 8, and the L-shaped limit plate 33 will break the contact with the slide plate 22 when guided by the inclined surface on the pry plate 9. At this time, the slide plate 22 will contact the guide plate 8, and the guide plate 8 will contact the inclined surface on the guide plate 8 during the continuous movement. At this time, the docking spring 34 pushes the fitting plate 26 to move. The fitting plate 26 contacts the telescopic rod 30 during the movement, and pushes the telescopic rod 30, the touch plate 28, and the slide plate 22 to move. When the guide plate 5 on the material placement table 1 contacts the L-shaped positioning frame 3, the slide plate 22 will enter the placement groove on the guide plate 8 and stop moving. At this time, the four protective plates 27 will move their positions, and the lens part of the industrial camera 19 will be exposed, and detection can be carried out.

[0050] A method for using an optical image detector for industrial camera detection, the method comprising the following steps:

[0051] Step 1: Place the product on the loading platform 1 and push the loading platform 1 to move it directly under the industrial camera 19. During the movement, the L-shaped limit plate 33 is pushed to rotate by the tripod plate 9 so that the slide plate 22 fits the guide plate 8.

[0052] Step 2: The slide plate 22 moves along the surface of the guide plate 8 during its movement, so that the protective plate 27 is moved away from directly below the industrial camera 19, and the product can be inspected;

[0053] Step three: After the inspection is completed, pull the loading table 1 to move. At this time, the arc cover plate 13 is rotated upward by the rotating shaft 11, and the four protective plates 27 are contracted by the reset spring 23 to provide protection for the bottom of the industrial camera 19 again. When the loading table 1 moves to the position where it is disconnected from the fixed plate 4, the loading table 1 can be rotated by connecting the rotating shaft 6 to make the products on the loading table 1 slide off, thereby preventing the loading table 1 from being stained when the staff takes the products.

[0054] When the present invention is in use, the product is placed at the center position of the top of the material placement table 1, and the material placement table 1 is pushed to move between the two fixed plates 4 until the guide plate 5 contacts the L-shaped positioning frame 3. During the movement of the material placement table 1, the tripod plate 9 pushes the L-shaped limit plate 33 to move, so that the slide plate 22 contacts the guide plate 8, and under the guidance of the guide plate 8, the slide plate 22 partially extends out of the translation groove 21. At this time, when the four protective plates 27 move their positions, the lens part of the industrial camera 19 is exposed, and the product is started to be inspected.

[0055] After the inspection is completed, the material placement table 1 is pulled to move and disengage from the contact with the fixed plate 4. At this time, the L-shaped limit plate 33 contacts the slide plate 22 and pushes the slide plate 22 into the translation slide groove 21, so that the four protective plates 27 and the protective cover 18 form a cover body to provide protection for the industrial camera 19 to prevent its lens from being stained. At this time, the material placement table 1 is tilted by rotating the connecting shaft 6, and the product on the material placement table 1 can be removed.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
