Description

Technical Field

[0001] This invention discloses a projector, and more particularly relates to a projector for use with optical components. Background Technology

[0002] Projectors used for optical components are used to detect the form and position tolerances, dimensional accuracy and surface quality of optical components, and to detect the contour and surface shape of optical components to ensure that the production and processing meet the design requirements. When in use, they are observed through high-definition optical lenses, and two-dimensional images of objects are acquired by optical imaging systems. Combined with image processing algorithms, precise dimensional measurements are achieved.

[0003] During use, components are placed on the worktable, and the device is turned on for detection and scanning. In existing technologies, to ensure the accuracy of scanning measurements, the lens of this device is usually cleaned regularly to prevent excessive dust from affecting the measurement. To address this issue and reduce dust, some large industries place this device in cleanrooms to reduce or avoid dust accumulation. However, most small industries can only place it in relatively enclosed or dust-free environments. Even with long-term use, dust will still accumulate. For ordinary detection or detection of larger objects, where the magnification and resolution do not need to be too high, a small amount of dust will not have a significant impact. However, when detecting smaller components that require more precise and clear images, the magnification is often increased, and the lens is moved closer to the component to shorten the distance. This makes the dust more magnified and clearer, affecting the measurement, reducing image clarity, and increasing edge detection errors. Therefore, a new solution is proposed: when the lens needs to be adjusted to move closer, a clearer image is required, and the device can automatically clean and absorb dust. Summary of the Invention

[0004] The purpose of this invention is to provide a projector for optical components in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a projector for optical components, comprising a column and a base connected to the column, a worktable for placing components on the base, a cover on the column, and an optical lens at the bottom of the cover, the optical lens and the cover being slidably connected by a fixing member, the cover having a connecting member that moves synchronously with the fixing member on the side of the fixing member, the connecting member being divided into a first connecting member and a second connecting member and distributed on the left and right sides of the fixing member, a storage box on the first connecting member on one side of the optical lens, a rotating member being rotatably connected to the second connecting member, a plurality of wiping papers for wiping the optical lens being provided in the storage box, and a pulling component for pulling the wiping papers to wipe the optical lens on the second connecting member;

[0006] The pulling assembly includes a gear 1 mounted on a rotating component, a rack that meshes with the gear 1 fixedly mounted on the cover at the connecting component 2, a protrusion fixedly mounted on the outer ring of the side of the rotating component, a pushing component rotatably connected to the connecting component 2 at the lower end of the gear, a driving component that extends towards the gear 1 fixedly mounted on the pushing component, a groove 1 that accommodates the protrusion to be embedded and pushed, a half gear rotatably connected to the pushing component, and a moving block that meshes with the half gear slidably connected to the bottom of the connecting component 2.

[0007] The moving block is fixedly connected to a crossbar at the end away from the pusher. The crossbar is equipped with a nozzle for spraying the optical lens. On both sides of the nozzle, the crossbar is equipped with a negative pressure suction head for adsorbing wiping paper. The connecting member is equipped with a guide groove for guiding the movement of the crossbar. The connecting member is equipped with a drive assembly for controlling the spraying of the nozzle and the opening of the negative pressure suction head.

[0008] Preferably, the drive assembly includes a switch that is disposed in a guide groove and abuts against a crossbar, and the cover is provided with a water storage device that is controlled by the switch to release water, and the water storage device is connected to the nozzle through a hose.

[0009] Preferably, the storage box has an opening at the bottom to accommodate a crossbar for inserting the absorbent wiping paper. The storage box has several rotating rollers on both sides of the opening that abut against the wiping paper. The storage box has a crossbar on the side away from the optical lens. The crossbar has a negative pressure suction head that functions the same as the negative pressure suction head. Both the negative pressure suction head and the negative pressure suction head are activated by a switch.

[0010] Preferably, the second crossbar is provided with a connecting rod that abuts against the first crossbar, the connecting rod is provided with a magnetic block 1 on the side near the optical lens, and the first crossbar is provided with a magnetic block 2 on the side near the optical lens and abutting against the connecting rod.

[0011] Preferably, the first connector is provided with a winding component at the rear end of the storage box and the second crossbar. A pull rope is wound around the winding component. One end of the pull rope is connected to the winding component and the other end is connected to the second crossbar. A spring connected to the first connector is provided inside the winding component. The elasticity of the spring is less than the magnetic force of the mutual attraction between the first and second magnetic blocks. The pulling force of the moving block is greater than the attraction force of the first and second magnetic blocks.

[0012] Preferably, the movable block and the crossbar are both provided with support rods, and the connectors are provided with guide grooves for the support rods. The guide grooves are staggered vertically. The guide groove includes three sections: groove 1, groove 2, and groove 3. Groove 1 is connected to groove 2, and the end of groove 2 away from groove 1 is connected to groove 3. The other end of groove 3 extends to groove 1 and is connected to groove 1. The end of groove 2 connected to groove 1 is lower than groove 1, while the end of groove 2 connected to groove 3 is higher than groove 3. The connection between groove 3 and groove 1 is higher than the connection between groove 1 and groove 2.

[0013] Preferably, both the connecting rod and the crossbar are provided with sliders embedded in the guide grooves, and springs are provided between the sliders and the connecting rod and the crossbar.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Firstly, when measuring small components using this device, the drive fixing component and optical lens are moved down along the cover. This causes the fixing component to move connector one and connector two down synchronously, and the rotating component and gear one on connector two also move down synchronously. As the gear moves down, it meshes with the rack on the cover. The fixed rack pushes gear one and the rotating component to rotate. The rotation of gear one causes the protrusion to revolve synchronously around the center of gear one. During rotation, the protrusion pushes the drive component to swing left and right along the slide groove one of the drive component, and drives the connected push component to rotate around the rotation point. This causes the half gear connected to the other end of the push component to rotate synchronously, and the teeth on the half gear mesh with the teeth of the bottom moving block, pushing the moving block forward. This causes the crossbar one to move into the storage box on the other side of the optical lens and to adhere to the wiping paper. As the crossbar moves, it comes into contact with switch one. Pressing switch one controls the nozzle and negative pressure suction head one to open, and the nozzle sprays cleaning fluid onto the optical lens. After the negative pressure suction head one adheres to and absorbs the wiping paper, the protrusion on gear one drives the drive component to swing and reset. During the reset process of the drive component, it drives the upper half gear of the push component to reverse, driving the moving block and crossbar one to reset. The crossbar one then pulls the wiping paper along the surface of the optical lens through the negative pressure suction head one, thus adhering to the surface of the optical lens and wiping it. The wiping paper removes the cleaning fluid and dust. The spraying of cleaning fluid can eliminate the static electricity caused by the friction between the wiping paper and the optical lens, thereby achieving an automatic cleaning effect. This ensures that when measuring smaller objects at higher magnification, the dust removal will not affect the measurement. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] A projector for optical components, such as Figures 1-9 As shown, the device includes a column 1 and a base 2 connected to the column 1. A worktable 3 for placing components is mounted on the base 2. A cover 4 is mounted on the column 1, and an optical lens 5 is located at the bottom of the cover 4. When using this device normally, if the component being measured is small, the optical lens 5 can be moved closer to the component using a side rocker or cylinder, and the magnification can be increased for easier measurement. For normal measurements where no adjustment of the optical lens 5 is needed, the object can be moved directly via the worktable 3 while the optical lens 5 remains fixed. Alternatively, the optical lens 5 can be moved left or right. However, except in cleanrooms, dust will gradually accumulate over time, reducing the image clarity of the optical lens 5 and affecting measurement accuracy. Therefore, manual cleaning is generally required before each use.

[0028] The optical lens 5 and the cover 4 are slidably connected by a fixing member 6. The cover 4 is provided with a connecting member on the side of the fixing member 6, which moves synchronously with the fixing member 6. The connecting member is divided into a first connecting member 7 and a second connecting member 8, which are distributed on the left and right sides of the fixing member 6. A storage box 9 is provided on the first connecting member 7 on one side of the optical lens 5. A rotating member 10 is rotatably connected to the second connecting member 8. The storage box 9 contains several wiping papers for wiping the optical lens 5. The second connecting member 8 is provided with a pulling component for pulling the wiping papers to wipe the optical lens 5. The pulling component includes a gear 11 provided on the rotating member 10. A rack 12 that meshes with the gear 11 is fixedly provided on the cover 4 at the second connecting member 8. A protrusion 13 is fixedly provided on the outer ring of the side of the rotating member 10. The second connecting member 8 is located at the gear 11. A pusher 14 is rotatably connected to the lower end of the device. A drive 15 extending towards gear 11 is fixedly mounted on the pusher 14. The drive 15 has a groove 16 for accommodating and pushing a protrusion 13. A half gear 17 is rotatably connected to the pusher 14. A moving block 18 that meshes with the half gear 17 is slidably connected to the bottom of the connector 8. A crossbar 19 is fixedly connected to the end of the moving block 18 away from the pusher 14. A nozzle 20 for spraying the optical lens 5 is mounted on the crossbar 19. Negative pressure suction heads 21 for adsorbing wiping paper are located on both sides of the nozzle 20 on the crossbar 19. When using this device, if it is necessary to move the optical lens 5 down to measure closer to the component, the internal fixing part 6 and the downward movement of the optical lens 5 are used simultaneously. The entire connecting piece 7 and connecting piece 8 move down synchronously and are fixed by the rack 12 on the side cover 4. Meanwhile, gear 11 and rotating piece 10 move down synchronously, thus engaging with the teeth of rack 12. The teeth of rack 12 push rotating piece 10 and gear 11 to rotate. Simultaneously, as gear 11 rotates, it drives the protrusion 13 on its outer ring to rotate synchronously along the center of gear 11. The protrusion 13, when rotating, pushes and swings the drive piece 15 along the slide groove 16 of the drive piece 15, causing the drive piece 15 to drive the pusher 14 to swing and rotate along the rotation point of the pusher 14. This, in turn, drives the connected half gear 17 to rotate synchronously. As half gear 17 rotates, its teeth drive the bottom meshing component to rotate. The moving block 18 moves towards the optical lens 5, causing the crossbar 19 to embed into the storage box 9. This causes the negative pressure suction head 21 on the crossbar 19 to adhere to the wiping paper. During the movement of the crossbar 19, it comes into contact with the switch, pressing the switch 23. This causes the switch 23 to control the water storage component 24 to spray cleaning fluid from the nozzle 20 onto the optical lens 5. At the same time, the negative pressure suction head 21 also opens, adhering to the wiping paper with suction force. Thus, when the protrusion 13 rotates to reset, it pushes the drive component 15 to reset, simultaneously pulling the push component 14 and the half gear 17 to rotate and reset. When the half gear 17 resets, it drives the meshing moving block 18 to reset as well, thereby pulling the crossbar 19 to reset and moving the wiping paper along the surface of the optical lens 5.This setup achieves the effect of wiping the surface of the optical lens 5 with cleaning fluid and removing dust. The proportions of the aforementioned structure can be adjusted according to the size of the device or the distance. By lowering the optical lens 5 closer to the components, it automatically cleans the lens, preventing excessive dust accumulation that could obscure the image when the magnification is increased. It also avoids dust affecting detection, reducing image clarity, and increasing edge detection errors.

[0029] The second connector 8 is provided with a guide groove 22 for guiding the movement of the crossbar 19. The second connector 8 is provided with a drive assembly for controlling the spraying of the nozzle 20 and the opening of the negative pressure suction head 21. The drive assembly includes a switch 23 disposed in the guide groove 22 and abutting against the crossbar 19. The cover 4 is provided with a water storage component 24 whose water output is controlled by the switch 23. The water storage component 24 is connected to the nozzle 20 through a hose. The storage box 9 has an opening 25 at the bottom to accommodate the crossbar 19 for inserting the absorbent wiping paper. Several rotating rollers 26 that abut against the wiping paper are located on both sides of the opening 25. A crossbar 27 is located on the side of the storage box 9 away from the optical lens 5. A negative pressure suction head 28 that functions the same as the negative pressure suction head 21 is located on the crossbar 27. Both the negative pressure suction head 21 and the negative pressure suction head 28 are activated by the switch 23. A connecting rod 29 that abuts against the crossbar 19 is located on the crossbar 27. A magnet 30 is located on the side of the connecting rod 29 near the optical lens 5. A magnet 31 is located on the side of the crossbar 19 near the optical lens 5 that abuts against the connecting rod 29.After being pushed by the half-gear 17, the moving block 18 will drive the crossbar 19 to move along the guide groove 22 and abut against and press the switch 23, causing the water storage device 24 to open and drain. Water will then be discharged through the hose into the nozzle 20. This setting is equivalent to an electrically controlled valve controlled by the switch 23. Each activation of the switch 23 controls the valve to open once and then automatically closes. This is existing technology and will not be discussed further here. It ensures that water is sprayed once after each activation. Then, wait for the crossbar 19 to open. The other side of the moving optical lens 5 will be embedded into the storage box 9 and inserted into the storage box 9 along the bottom opening 25, adhering to the wiping paper. At the same time, when switch 1 23 is turned on, the negative pressure suction head 1 21 will also turn on, so that the wiping paper can be tightly adsorbed when it is attached, and the wiping paper can be moved together when the crossbar 1 19 is reset. When the crossbar 1 19 is embedded into the opening 25, the crossbar 1 19 will be attached to the connecting rod 29, and will be attached to each other through the magnetic block 1 30 and the magnetic block 2 31. The adsorption mechanism connects the crossbar 19 to the connecting rod 29, ensuring that when the crossbar 19 resets, it can pull the connecting rod 29 and the crossbar 27 to move synchronously. When the switch 23 is turned on, the negative pressure suction head 28 also turns on simultaneously, adsorbing the attached wiping paper. Thus, when the wiping paper in the storage box 9 is pulled, both ends of the wiping paper move steadily, resulting in more stable wiping. In contrast, if only one end is fixed, and the wiping paper is pulled along the optical lens 5, the other end will droop and fail to adhere to the optical lens 5, meaning only one end is ever wiped, potentially leaving dust residue. By supporting the wiping paper at both ends, the entire wiping paper can adhere to and move with the optical lens 5. When the wiping paper at the front end, connected to the negative pressure suction head 21, first comes into contact with more dust, if it is not cleaned properly, the rear wiping paper continues to move, providing multiple cleaning steps and preventing dirt and dust residue. This design improves the cleaning effect.

[0030] Connector 1 7 is located at the rear end of storage box 9 and crossbar 2 27 and has a winding component 32. A pull rope 33 is wound on the winding component 32. One end of the pull rope 33 is connected to the winding component 32 and the other end is connected to the crossbar 2 27. The winding component 32 has a spring 34 connected to connector 1 7. The pulling force of the moving block 18 is greater than the attraction force of magnetic block 1 30 and magnetic block 2 31. After the crossbar 27 is moved by the connecting rod 29, it will simultaneously pull and unfold the pull rope 33. The unfolding of the pull rope 33 will also cause the winding component 32 to rotate, compressing the spring 34 to ensure the synchronous movement of the crossbar 27. The elasticity of the spring 34 is less than the magnetic force of the attraction between the first magnet 30 and the second magnet 31, thus ensuring that the crossbar 19 pulls the connecting rod 29 and the crossbar 27 without separating the first magnet 30 and the second magnet 31. Therefore, when pulled, the wiping paper moves along the rotating roller 26, avoiding excessive friction that hinders movement. The rotation of the rotating roller 26 makes the movement of the wiping paper smoother. After the first horizontal bar 19 is fully reset, and the connecting rod 29 and the second horizontal bar 27 are pulled until the pull rope 33 is fully extended, the first horizontal bar 19 continues to move backward. The interaction between the pulling force of the first horizontal bar 19 and the constraint of the pull rope 33 causes the first magnetic block 30 and the second magnetic block 31 to separate, thus escaping the pulling force of the first horizontal bar 19. The elastic force of the spring 34 will drive the winding component 32 to reset, and the winding pull rope 33 will simultaneously pull the second horizontal bar 27 and the connecting rod 29 to reset and re-fit into the storage box 9. Through the above settings, it is ensured that the second horizontal bar 27 can move synchronously and automatically reset, while also ensuring continuous reuse.

[0031] Both the movable block 18 and the crossbar 27 are equipped with support rods 35. The connecting piece 28 and the connecting piece 17 are equipped with guide grooves 26 for guiding the support rods 35. The sliding groove 2 and the guide groove 1 are vertically offset. The guide groove 1 22 includes three sections: groove 1 37, groove 2 38, and groove 39. Groove 1 37 communicates with groove 2 38, and the end of groove 2 38 furthest from groove 1 37 communicates with groove 39. The other end of groove 39 extends to groove 1 37 and communicates with it. The end of groove 2 38 communicating with groove 1 37 is lower than groove 1 37, while the end of groove 2 38 communicating with groove 39 is higher than groove 39. The connection point between groove 39 and groove 1 37 is higher than the connection point between groove 1 37 and groove 2 38. Both the connecting rod 29 and the crossbar 19 are equipped with sliders 40 embedded in the guide groove 1 22. A spring 41 is provided between the slider 40 and the connecting rod 29 and the crossbar 19.When the movable block 18 is pushed, the support rod 35 on the side of the movable block 18 moves along the second guide groove 36, while the slider 40 on the side of the crossbar 19 moves along the first groove 37 of the first guide groove 22. When it moves to the connection between groove 37, groove 2, and groove 39, the thickness of groove 39 at this point is greater than that at the connection between groove 1, 37 and groove 2, 38, thus blocking the slider 40 from moving along groove 39. This forces the slider 40 to enter groove 2, 38, which is lower than groove 1, 37, and continue moving forward. As it moves forward into groove 2, 38, the middle position of groove 2, 38 is lower than groove 1, 37, and groove 39, causing the crossbar 19 to drive the movable block 18 to rotate along the support rod 35. The horizontal bar 19 is lowered slightly, causing the nozzle 20 to move downwards and create a certain distance between it and the optical lens 5. This prevents the nozzle from adhering to the optical lens 5 before the wiping paper is absorbed. As the slider 40 on the horizontal bar 19 moves along the groove 2 38 to the end of the groove 2 38 where it connects with the groove 3 39, the groove 2 38 thickens and becomes higher than the groove 3 39. When the horizontal bar 19 enters the groove 3 39, it also rises again and adheres to the wiping paper, aligning with the height of the optical lens 5. After the moving block 18 is moved and reset by the half-gear 17, it resets the horizontal bar 19, causing the slider 40 on the horizontal bar 19 and the slider 40 on the connecting rod 29 to move along the groove 3 39 and become higher than the groove 3 39. The groove 38 at the second position prevents the connecting rod 29 from moving downwards into the groove 38, thus ensuring that the horizontal bar 19 pulls the connecting rod 29 to move in contact with the optical lens 5, thereby ensuring that the wiping paper is in contact with the optical lens 5 to wipe the optical lens 5. Similarly, when the slider 40 on the connecting rod 29 is driven to move along the groove 39 to the groove 137 and needs to be reset, it will be consistent with the path of the slider 40 on the horizontal bar 19 moving towards the storage position. During the movement, the guide groove 122 and the guide groove 26 are misaligned to ensure that the movement path of the horizontal bar 19 and the connecting rod 29 is synchronized, while the movement path of the horizontal bar 27 and the moving block 18 is consistent, thus avoiding the problem of confusion and mutual interference caused by the intersection. Through the above settings, the horizontal bar 19 and the horizontal bar 29 can be guaranteed to move in a synchronized manner. When lever 27 is not adsorbing the wiping paper, it will not adhere to the optical lens 5, ensuring that the optical lens 5 is not scratched during movement. When adsorbing and wiping the lens, it will lift and move so that the wiping paper adheres to the optical lens 5, thus ensuring the wiping and cleaning of the optical lens 5. Finally, a cylinder can be installed in the fixing part 6. Its switch is connected to gear 11. When gear 11 rotates, cylinder 1 automatically opens, causing the lens to retract upward to the same height as the head. After cleaning the optical lens 5, the cylinder resets, causing the optical lens 5 to protrude, which makes cleaning more convenient. At the same time, the protruding optical lens 5 also makes it easier to wipe manually. Finally, after the wiping paper is wiped, the automatic suction stops and the wiping paper will fall down, which the operator can directly remove.
