Description
Technical Field
[0001] This utility model relates to the technical field of support devices, specifically a support device for inspecting the appearance of plastic shells. Background Technology
[0002] In the production process of plastic casings, visual inspection is a crucial step in ensuring product quality. Accurate and comprehensive inspection of the plastic casing's appearance can promptly detect defects such as scratches, cracks, deformation, and color differences on the casing's surface.
[0003] The most common method for inspecting the appearance of plastic casings is manual inspection. Operators place the plastic casing on a simple support platform and observe its appearance by hand or with the naked eye. Most existing support platforms are simple in structure, providing only basic placement functions and unable to allow for flexible rotation of the plastic casing. During the inspection process, operators need to move the plastic casing constantly to observe its appearance from different angles, making it difficult to conduct a comprehensive inspection of all parts of the casing and easily leading to omissions. When rotating the plastic casing for appearance inspection, operators find it difficult to accurately determine whether it has been rotated to the preset angle, which can easily lead to omissions or repeated inspections. Therefore, a support device for the appearance inspection of plastic casings is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a support device for inspecting the appearance of plastic shells, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a support device for inspecting the appearance of a plastic shell, comprising an operating table, a turntable on the top of the operating table, and a plastic shell body placed on the top of the turntable; The top of the operating table is equipped with a rotating component, which is used to drive the plastic housing body of the appearance inspection to rotate circumferentially. A limiting component is provided on one side of the rotating component, and the limiting component is used to indicate the rotation angle of the plastic shell body; The rotating assembly includes a fixed frame, a connecting frame fixed to the top of the fixed frame, a placement groove provided on the inner side of the connecting frame, a second rotating shaft rotatably connected to the inner wall of the placement groove, and a worm gear fixed to the outer side of the second rotating shaft; The inner wall of the fixed frame is rotatably connected to a first rotating shaft, and a worm gear is fixedly sleeved on the outer side of the first rotating shaft.
[0006] Preferably, the worm gear is meshed with a worm wheel, the worm wheel is located inside the placement groove, and the top of the turntable is provided with anti-slip texture.
[0007] Preferably, a handwheel is fixed to one end of the second rotating shaft; When the worm gear meshes with the worm wheel, it drives the turntable to rotate.
[0008] Preferably, the first rotating shaft is fixed at the bottom center of the turntable, and the fixing bracket is fixed to the top of the operating table.
[0009] Preferably, a light is installed on the top of the operating table, and a background panel is installed on one side of the operating table.
[0010] Preferably, the limiting component includes a support frame, the support frame having a groove inside, and a sliding plate slidably connected to the inner side of the groove.
[0011] Preferably, a plurality of limiting grooves are provided on the outer side of the first rotating shaft, a protrusion is fixed on one side of the slide block, a ball socket is provided on one side of the protrusion, a ball is ball-connected to the inner side of the ball socket, and the ball is adapted to the inner side of the limiting groove.
[0012] Preferably, a cover plate is bolted to one side of the support frame, and a spring is connected between the cover plate and the slide plate. The support frame is fixed to the outside of the fixed frame.
[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: 1. Through the worm gear-worm wheel transmission structure of the rotating component, the operator only needs to turn the handwheel to drive the turntable and the plastic housing body to achieve circumferential rotation. The meshing transmission of the worm and worm wheel has a self-locking characteristic. After the turntable is adjusted to the target angle, it can automatically lock the position to prevent accidental rotation caused by external force during the inspection process, thus meeting the requirements of 360° all-round appearance inspection.
[0014] Second, by switching the state of the ball between the limiting groove and the outer wall of the first rotating shaft, the obvious jamming sensation when the ball is inserted into a certain limiting groove, and the "click" sound and jerking sensation in the hand when the ball is ejected from the current limiting groove and bounced into the new limiting groove during subsequent rotation, the operator is provided with a clear and definite signal indicating that the ball has been rotated to the preset angle. This avoids situations where the operator cannot accurately judge the rotation angle, resulting in missed detections or repeated detections. Attached Figure Description

[0020] Example Please see Figure 1-5 This utility model provides a technical solution: a support device for inspecting the appearance of a plastic shell, including an operating table 1, a turntable 6 on the top of the operating table 1, the turntable 6 being made of plastic and having a rubber layer on the top, and a plastic shell body 7 placed on the top of the turntable 6; an illumination lamp 2 is installed on the top of the operating table 1, the illumination lamp 2 being a planar light source or a ring light source, and a background plate 4 is installed on one side of the operating table 1, the background plate 4 being pure black, pure white, or other standard contrasting colors. In this embodiment, the support device can be used for manual visual inspection of the outside of the plastic shell body 7, or it can be rotated with manual assistance and photographed by a camera.
[0021] The top of the operating table 1 is equipped with a rotating component 3, which is used to drive the plastic housing body 7 for appearance inspection to rotate circumferentially; a limiting component 5 is provided on one side of the rotating component 3, which is used to indicate the rotation angle of the plastic housing body 7. The rotating assembly 3 includes a fixed frame 31, a connecting frame 33 fixed to the top of the fixed frame 31, a placement groove 37 provided on the inner side of the connecting frame 33, a second rotating shaft 36 rotatably connected to the inner wall of the placement groove 37, and a worm gear 38 fixed to the outer side of the second rotating shaft 36; a first rotating shaft 32 rotatably connected to the inner wall of the fixed frame 31, and a worm wheel 35 fixedly sleeved on the outer side of the first rotating shaft 32.
[0022] The worm 38 is meshed with the worm wheel 35, which is located inside the placement groove 37. The top of the turntable 6 is provided with anti-slip texture. A handwheel 34 is fixed to one end of the second rotating shaft 36. When the worm 38 and the worm wheel 35 mesh and drive, the turntable 6 is rotated. The inspector rotates the handwheel 34 by hand. The rotation of the handwheel 34 drives the second rotating shaft 36 and the worm 38 fixed thereto to rotate together in the placement groove 37.
[0023] The first rotating shaft 32 is fixed at the bottom center of the turntable 6, and the fixing bracket 31 is fixed to the top of the operating table 1. The rotating worm 38 meshes with the worm wheel 35. Due to the characteristics of the worm wheel 35 and worm 38 mechanism, the worm 38 can easily drive the worm wheel 35, but the reverse is difficult. This forms a self-locking mechanism, which allows the turntable 6 to stop stably at any angle and not to rotate on its own due to external force. The worm wheel 35 transmits the rotational motion to the turntable 6 through the first rotating shaft 32. The turntable 6 drives the plastic housing body 7 on it to achieve a slow circumferential rotation, which makes it convenient for the inspector to observe every angle of its side from a fixed position.
[0024] The limiting component 5 includes a support frame 51, with a groove 53 inside the support frame 51. A slide plate 56 is slidably connected to the inside of the groove 53. Several limiting grooves 58 are provided on the outside of the first rotating shaft 32. A protrusion 54 is fixed on one side of the slide plate 56. A ball socket is provided on one side of the protrusion 54. A ball 55 is ball-connected to the inside of the ball socket. The ball 55 is adapted to the inside of the limiting groove 58. Under the elastic force of the spring 57, the slide plate 56 is pushed towards the direction of the first rotating shaft 32 in the groove 53. When the turntable 6 needs to be rotated, the torque applied by the operator to the handwheel 34 will overcome the elastic force of the spring 57, forcing the ball 55 to slide out of the current limiting groove 58. The first rotating shaft 32 rotates accordingly. When the first rotating shaft 32 rotates to the position where the next limiting groove 58 is aligned with the ball 55, the ball 55 will quickly spring into the new limiting groove 58 with a "click" under the action of the spring 57. The "click" sound and the jolt in the hand are a clear indication signal that a preset angle has been rotated. The angle range of the adjacent limiting grooves 58 is 30°-120°.
[0025] A cover plate 52 is bolted to one side of the support frame 51. A spring 57 is connected between the cover plate 52 and the slide plate 56. The support frame 51 is fixed to the outside of the fixed frame 31. The bolts on one side of the cover plate 52 are removed periodically, and the spring 57 is taken out and replaced. The spring 57 has a certain compression and a certain elastic potential energy.
[0026] Working principle: First, the plastic shell body 7 to be inspected is placed on the turntable 6 on the top of the operating table 1. Because the top of the turntable 6 has anti-slip texture, the plastic shell body 7 can be prevented from shifting during the inspection process. At the same time, the lighting lamp 2 installed on the top of the operating table 1 provides sufficient light, and together with the background plate 4 on one side of the operating table 1, a clear observation environment is created for appearance inspection. When the angle of the plastic housing body 7 needs to be adjusted for comprehensive appearance inspection, the operator rotates the handwheel 34 at one end of the second rotating shaft 36 in the rotating assembly 3, causing the second rotating shaft 36 to rotate within the inner wall of the placement groove 37 on the inner side of the connecting frame 33. Since a worm 38 is fixed to the outside of the second rotating shaft 36, and the worm 38 is meshed with a worm wheel 35 fixedly sleeved on the outside of the first rotating shaft 32, according to the transmission principle of the worm 38 and worm wheel 35, the rotation of the worm 38 will drive the worm wheel 35 to rotate synchronously. Furthermore, since the first rotating shaft 32 is fixed at the bottom axis of the turntable 6, and the first rotating shaft 32 is rotatably connected to the inner wall of the fixed frame 31, the worm wheel 35 ultimately drives the first rotating shaft 32 to rotate, thereby enabling the turntable 6 and the plastic housing body 7 above it to achieve circumferential rotation, meeting the inspection requirements at different angles. When the first rotating shaft 32 rotates with the turntable 6, the ball 55 switches between the limiting groove 58 and the outer wall of the first rotating shaft 32: when the ball 55 is stuck in a certain limiting groove 58, a clear jamming sensation will be produced, indicating to the operator that the current rotation has reached the preset angle; if it is necessary to continue rotating, the operator needs to apply a larger torque to drive the first rotating shaft 32 through the handwheel 34 to overcome the elastic force of the spring 57, so that the ball 55 is dislodged from the current limiting groove 58 and slides to the adjacent limiting groove 58. Under the action of the spring 57, the ball 55 will quickly spring into the new limiting groove 58 with a "click". The "click" sound and the jerking sensation in the hand are a clear indication signal that a preset angle has been rotated. Repeating this process can achieve the indication of the rotation angle.
[0027] After all angles of the plastic housing body 7 have been inspected, stop turning the handwheel 34. At this time, the ball 55 will be inserted into the nearest limiting groove 58, keeping the turntable 6 stable. The operator can then remove the inspected plastic housing body 7 to complete one inspection process.
[0028] In summary, through the worm gear 38-worm wheel 35 transmission structure of the rotating component 3, the operator only needs to turn the handwheel 34 to drive the turntable 6 and the plastic housing body 7 to achieve circumferential rotation. The meshing transmission of the worm gear 38 and the worm wheel 35 has a self-locking characteristic. After the turntable 6 is adjusted to the target angle, it can automatically lock the position to prevent accidental rotation caused by external force during the inspection process, thus meeting the requirements of 360° all-round appearance inspection.
[0029] By switching the state of the ball 55 between the limiting groove 58 and the outer wall of the first rotating shaft 32, the obvious jamming sensation when it is inserted into a certain limiting groove 58, and the "click" sound and hand-feeling jolt as the ball 55 detaches from the current limiting groove 58 and bounces into the new limiting groove 58 during subsequent rotation, provide the operator with a clear and definite signal indicating that the preset angle has been reached. This avoids situations where the operator cannot accurately judge the rotation angle, resulting in missed detections or repeated detections.
