Description

Technical Field

[0001] This invention relates to the field of workpiece coating technology, specifically a rotation angle detection device based on workpiece coating. Background Technology

[0002] In the field of workpiece coating technology, high-quality coating of workpieces is a crucial step in ensuring product performance and appearance. However, the detection and control of rotation angle during the coating process currently faces numerous challenges, becoming a significant factor restricting the improvement of coating quality.

[0003] For example, CN218329814U discloses a workpiece disk rotation angle detection device for use in coating equipment, including a workpiece disk rotation device. One end of the workpiece disk rotation device is fixedly connected to the inside of a vacuum chamber via a connecting shaft, and the other end is detachably connected to a workpiece disk. The other end of the connecting shaft is connected to an angle detection device, which is located outside the vacuum chamber.

[0004] This patent connects a workpiece disk rotation device set inside a vacuum chamber to a connecting shaft, and sets an angle detection device at the other end of the connecting shaft. The angle detection device is set outside the vacuum chamber. The angle detection device can not only measure the rotation angle of the workpiece disk relatively accurately, but some devices rely on simple mechanical limits or rough angle markings to determine the rotation angle of the workpiece. This is difficult to meet the increasingly stringent requirements of modern industry for coating precision. For example, in the coating process of precision optical instruments, even a small angular deviation may lead to uneven film thickness, which will affect optical performance and cause abnormal light refraction and reduced imaging quality. Summary of the Invention

[0005] To address the issue that even minute angular deviations in the coating process of precision optical instruments can lead to uneven film thickness, thereby affecting optical performance and causing abnormal light refraction and reduced image quality, this invention proposes a rotation angle detection device based on workpiece coating.

[0006] The technical solution adopted by this invention to solve its technical problem is: a rotation angle detection device based on workpiece coating, comprising a base plate:

[0007] An angle adjustment mechanism and a moving mechanism are fixedly connected to the top of the base plate;

[0008] The angle adjustment mechanism includes a first fixed column, which is fixedly connected to the top of the base plate. A first connecting column is fixedly connected to one end of the first fixed column. A worm gear is fixedly connected to the outer side of the first connecting column. A locking column is movably connected to the inner cavity of the first fixed column. A second connecting column is fixedly connected to the top of the locking column. A discharge column is fixedly connected to the top of the second connecting column. A worm is movably connected to the inner cavity of the discharge column. The worm and the worm gear are meshed together.

[0009] Preferably, the angle adjustment mechanism further includes a scale, which is fixedly opened in the inner cavity on one side of the fixed column, and the scale has a scale portion with measuring function.

[0010] Preferably, the angle adjustment mechanism further includes a baffle, which is fixedly connected to one end of the feeding column, movably disposed at one end of the worm gear, and the end of the feeding column away from the baffle is fixedly connected to a motor.

[0011] Preferably, the angle adjustment mechanism further includes a controller, which is fixedly connected to one end of the feeding column. The inner cavity at the top of the feeding column is provided with a feeding groove, and the end of the feeding column near the scale is provided with an angle mark.

[0012] Preferably, the moving mechanism includes a second fixed column, which is fixedly connected to the top of the base plate. A third connecting column is fixedly connected to the top of the second fixed column, and a second motor is fixedly connected to the top of the third connecting column.

[0013] Preferably, the moving mechanism further includes a moving frame, which is fixedly connected to one end of the connecting column three. A screw is movably connected to the inner cavity of the moving frame, and the screw is connected to the motor two through the moving frame. A moving shaft is fixedly connected to the inner cavity of the moving frame.

[0014] Preferably, the moving mechanism further includes a moving column, which is movably connected to the outside of the moving shaft and the screw. The inner cavity of the moving column is threaded, and the thread engages with the thread on the surface of the screw.

[0015] Preferably, the moving mechanism further includes a cylinder, which is fixedly connected to the bottom end of the moving column. A telescopic rod is fixedly connected to the bottom end of the cylinder, and a coating device is fixedly connected to the bottom end of the telescopic rod.

[0016] The advantages of this invention are:

[0017] 1. This invention utilizes an angle adjustment mechanism to drive a feeding column to rotate via a motor. The rotation of the feeding column is transmitted to the worm gear and related structures through the meshing of a worm and worm wheel, thus enabling the feeding column to rotate the workpiece. Simultaneously, a scale and angle markings are used to measure the rotation angle, a baffle ensures transmission stability, and a controller precisely controls the operation of the motor. This allows for accurate detection and control of the workpiece's rotation angle during coating. The angle adjustment mechanism allows for multi-angle adjustment of the workpiece, facilitating coating from multiple directions.

[0018] 2. This invention utilizes a structural design for a moving mechanism. A motor drives a screw to rotate, and through the threaded engagement between the screw and the moving column, the moving column moves linearly under the guidance of a moving shaft, achieving horizontal displacement adjustment. Furthermore, a cylinder controls the extension and retraction of a telescopic rod, adjusting the height of the coating device. This allows the coating device to coat the workpiece at different positions. In conjunction with an angle adjustment mechanism, it completes coating work on the workpiece at different angles and positions. 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. Obviously, the described embodiments are only some embodiments of the present invention, and 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] Example 1

[0028] Please see Figures 1-3 As shown, a rotation angle detection device based on workpiece coating includes a base plate 1:

[0029] An angle adjustment mechanism 2 and a moving mechanism 3 are fixedly connected to the top of the base plate 1;

[0030] The angle adjustment mechanism 2 includes a first fixed column 201, which is fixedly connected to the top of the base plate 1. One end of the first fixed column 201 is fixedly connected to a first connecting column 202. A worm gear 203 is fixedly connected to the outer side of the first connecting column 202. A locking column 205 is movably connected to the inner cavity of the first fixed column 201. A second connecting column 206 is fixedly connected to the top of the locking column 205. A discharge column 207 is fixedly connected to the top of the second connecting column 206. A worm 208 is movably connected to the inner cavity of the discharge column 207. The worm 208 and the worm gear 203 are meshed together.

[0031] During operation, the workpiece to be coated is placed in the feeding groove 212 at the top of the feeding column 207. The motor 210 is started, which drives the feeding column 207 to rotate. When the feeding column 207 rotates, it drives the worm gear 208 to rotate synchronously. Since the worm gear 208 and the worm wheel 203 are meshed, the rotation of the worm gear 208 will drive the worm wheel 203 to rotate, which in turn drives the connecting column 202, the fixing column 201, and the locking column 205 to rotate. Finally, the feeding column 207 drives the workpiece to rotate, which facilitates coating operations on the workpiece at different angles.

[0032] Furthermore, the angle adjustment mechanism 2 also includes a scale 204, which is fixedly opened in the inner cavity at the side end of the fixed column 201. The scale 204 has a scale portion with measuring function.

[0033] During operation, as the feeding column 207 drives the workpiece to rotate, the operator can intuitively understand the rotation angle of the feeding column 207 and the workpiece by observing the correspondence between the angle mark 213 at the end of the feeding column 207 near the scale 204 and the scale 204, thereby accurately controlling the coating angle.

[0034] Furthermore, the angle adjustment mechanism 2 also includes a baffle 209, which is fixedly connected to one end of the feeding column 207, and is movably disposed at one end of the worm gear 208. The end of the feeding column 207 away from the baffle 209 is fixedly connected to the motor 210.

[0035] During operation, the baffle 209 plays a certain limiting role, preventing the worm 208 from axially moving during rotation, ensuring that the worm 208 and the worm wheel 203 always maintain a good meshing state, ensuring the stability of the transmission, and thus ensuring the accuracy of the workpiece rotation angle driven by the feed column 207.

[0036] Furthermore, the angle adjustment mechanism 2 also includes a controller 211, which is fixedly connected to one end of the feeding column 207. The inner cavity at the top of the feeding column 207 is provided with a feeding groove 212, and the end of the feeding column 207 near the scale 204 is provided with an angle mark 213.

[0037] During operation, the controller 211 can control the operation of the motor 210, such as controlling the start, stop, and speed of the motor 210. By adjusting the speed of the motor 210, the rotation speed of the workpiece driven by the feeding column 207 can be adjusted. Combined with the angle mark 213 and the scale 204, the rotation angle required for workpiece coating can be controlled more precisely.

[0038] Working principle: The feeding column 207 is driven to rotate by motor 210. The rotation of the feeding column 207 is transmitted to the worm wheel 203 and related structures through the meshing transmission of worm gear 208 and worm wheel 203, thus enabling the feeding column 207 to drive the workpiece to rotate. Simultaneously, the rotation angle is measured using scale 204 and angle marker 213, and the transmission stability is ensured by baffle 209. The operation of motor 210 is precisely controlled by controller 211, thereby achieving accurate detection and control of the workpiece coating rotation angle.

[0039] Example 2

[0040] Please see Figures 4-5 As shown, in contrast to Embodiment 1, which is another implementation of the present invention, a moving mechanism 3 is also included:

[0041] The moving mechanism 3 includes a second fixed column 301, which is fixedly connected to the top of the base plate 1. A third connecting column 302 is fixedly connected to the top of the second fixed column 301, and a second motor 303 is fixedly connected to the top of the third connecting column 302.

[0042] When in operation, motor 2 303 is started, which drives the connecting column 3 302 to rotate. When the connecting column 3 302 rotates, it drives the moving frame 304 and other structures connected to it to move.

[0043] Furthermore, the moving mechanism 3 also includes a moving frame 304, which is fixedly connected to one end of the connecting column 302. A screw 305 is movably connected to the inner cavity of the moving frame 304. The screw 305 is connected to the motor 303 through the moving frame 304. A moving shaft 306 is fixedly connected to the inner cavity of the moving frame 304.

[0044] During operation, motor 303 drives screw 305 to rotate within movable frame 304. Since the inner cavity of movable column 307 has a thread that meshes with the thread on the surface of screw 305, and movable column 307 is also movably connected to movable shaft 306, when screw 305 rotates, movable column 307 will move linearly along the axial direction of screw 305 under the restriction of movable shaft 306.

[0045] Furthermore, the moving mechanism 3 also includes a moving column 307, which is movably connected to the outside of the moving shaft 306 and the screw 305. The inner cavity of the moving column 307 is provided with threads, which are engaged with the threads on the surface of the screw 305.

[0046] During operation, the movable column 307 is driven by the screw 305 to translate along the direction of the movable shaft 306, thereby achieving horizontal position adjustment and driving the cylinder 308 and the coating device 310 fixed at its bottom to move together.

[0047] Furthermore, the moving mechanism 3 also includes a cylinder 308, which is fixedly connected to the bottom end of the moving column 307. A telescopic rod 309 is fixedly connected to the bottom end of the cylinder 308, and a coating device 310 is fixedly connected to the bottom end of the telescopic rod 309.

[0048] During operation, when the moving column 307 moves the cylinder 308 and the coating device 310 to a suitable horizontal position, the cylinder 308 is activated, and the telescopic rod 309 of the cylinder 308 extends or retracts to adjust the height of the coating device 310 so that the coating device 310 can reach the appropriate coating position on the workpiece surface to perform the coating operation.

[0049] Working principle: Motor 303 drives screw 305 to rotate. Through the threaded engagement between screw 305 and moving column 307, moving column 307 moves linearly under the guidance of moving shaft 306, achieving horizontal displacement adjustment. Cylinder 308 controls the extension and retraction of telescopic rod 309, adjusting the height of coating device 310, allowing it to coat the workpiece at different positions. In conjunction with angle adjustment mechanism 2, it completes coating work on the workpiece at different angles and positions.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
