Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to a rotary testing device. Background Technology

[0002] In automated inspection, there is often a need for multi-directional inspection to achieve clear and comprehensive product imaging for defect detection. For example, in automated lens inspection, because lenses have many layers and complex shapes, the inspection camera needs to shoot the edges of each lens from above or below the lens at an angle. However, this method can only illuminate a corner of the lens, so the inspection position needs to have the function of rotating the lens itself to meet the requirement of inspecting the edges of each lens globally.

[0003] To address this, existing testing equipment on the market typically achieves the rotation function of the testing position by adding numerous drive structures, such as equipping each station with a separate motor to drive the rotation of the testing position. These structures obstruct the installation space of the testing light source and testing camera, require a large overall testing station space, and are costly and difficult to miniaturize and lighten. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by proposing a rotary testing device that can quickly switch between or connect to different workstations and realize the rotation of the workpiece under test. It is small, lightweight, and low in cost.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model proposes a turntable-type inspection device, including a first motor, a turntable, a rotating wheel, multiple workpiece inspection units, a second mounting base, and a second motor. The first motor is used to drive the turntable to rotate. The second mounting base is connected to the turntable. The second motor is connected to the second mounting base and is used to drive the rotating wheel to rotate. The rotation axes of the turntable and the rotating wheel are coaxial. Each workpiece inspection unit is circumferentially distributed on the turntable, and each workpiece inspection unit includes a rotating seat for accommodating the workpiece to be inspected. The rotating seat is rotatably connected to the turntable and achieves rotation through the rotating wheel. The rotation axes of the rotating seat and the rotating wheel are parallel.

[0007] Preferably, the rotary detection device further includes a belt, which is sleeved on the outside of the rotating wheel and contacts each rotating seat.

[0008] Preferably, the workpiece inspection unit further includes a bearing, a snap ring, and several screws. The rotating seat is rotatably connected to the turntable via the bearing. The snap ring is attached to the rotating seat and used to limit the axial movement of the rotating seat. The screws are connected to the turntable and used to limit the axial movement of the bearing.

[0009] Preferably, the rotary detection device further includes a first reducer and a second reducer, wherein the first motor drives the rotary table to rotate through the first reducer, and the second motor drives the rotating wheel to rotate through the second reducer.

[0010] Preferably, the rotary detection device further includes a position detection unit, which includes a position sensor and a sensing plate. The position sensor is connected to the fixed part of the second motor, and the sensing plate is connected to the rotating part of the second motor.

[0011] Preferably, the rotary detection device further includes a conductive slip ring, which is coaxially mounted on the rotary table and electrically connected to the second motor and the position detection unit.

[0012] Preferably, the rotary detection device further includes a connecting seat, which is connected to the rotating part of the first motor and the rotary table respectively, and a conductive slip ring is built into the connecting seat.

[0013] Preferably, there are eight workpiece detection units, which are evenly distributed around the turntable.

[0014] Preferably, the rotary detection device further includes a first mounting base, and a first motor is mounted on an external device via the first mounting base. The external device includes a frame and at least one camera. Both the first mounting base and the camera are connected to the frame. The camera is used to photograph the workpiece to be tested in the workpiece detection unit.

[0015] Preferably, both the first motor and the second motor are stepper motors.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] While the device rotates the turntable to realize the flow of workstations, it can also contact the workpiece detection unit through the rotating wheel. Under the action of the rotating wheel, the workpiece detection unit is driven to rotate at all workstations, thereby driving the workpiece to be tested to rotate and complete the detection. The rotation of the workpiece detection unit at each workstation can be achieved by a single motor drive, reducing the installation of electrical and mechanical components. The structure is simple and provides more installation space for the detection equipment. It can also quickly switch between different workstations, resulting in high work efficiency, small size, lightweight design, and low cost. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application.

[0027] like Figure 1-6 As shown, a rotary table inspection device includes a first motor 1, a turntable 4, a rotating wheel 5, multiple workpiece inspection units 7, a second mounting base 8, and a second motor 9. The first motor 1 drives the turntable 4 to rotate. The second mounting base 8 is connected to the turntable 4. The second motor 9 is connected to the second mounting base 8 and drives the rotating wheel 5 to rotate. The rotation axes of the turntable 4 and the rotating wheel 5 are coaxial. Each workpiece inspection unit 7 is circumferentially distributed on the turntable 4, and each workpiece inspection unit 7 includes a rotating seat 71 for accommodating the workpiece 11 to be inspected. The rotating seat 71 is rotatably connected to the turntable 4 and is driven to rotate by the rotating wheel 5. The rotation axes of the rotating seat 71 and the rotating wheel 5 are parallel.

[0028] The workpiece 11 to be tested, such as a lens, is placed in the rotating seat 71 of the workpiece detection unit 7. The first motor 1 drives the turntable 4 to rotate to realize the station flow, and the second motor 9 drives the rotating wheel 5 to rotate. The rotating wheel 5 and the workpiece detection unit 7 are driven by the belt 6 to realize the rotation of all stations, thereby driving the workpiece 11 to be tested to rotate for detection.

[0029] In one embodiment, the rotary detection device further includes a belt 6, which is sleeved around the rotating wheel 5 and contacts each rotating seat 71. The uniform contact between the belt 6 and the rotating seat 71 reduces friction noise and facilitates replacement and maintenance. It is readily understood that the rotating seat 71 is rotatably connected to the turntable 4 and driven by the rotating wheel 5 to achieve rotation; other methods in the prior art, such as achieving rotation through gear meshing, can also be used.

[0030] In one embodiment, the workpiece inspection unit 7 further includes a bearing 72, a retaining ring 73, and several screws 74. The rotating seat 71 is rotatably connected to the turntable 4 via the bearing 72. The retaining ring 73 is engaged with the rotating seat 71 and is used to limit the axial movement of the rotating seat 71. The screws 74 are connected to the turntable 4 and are used to limit the axial movement of the bearing 72. The screws 74 and the retaining ring 73 ensure that the rotating seat 71 is securely installed and rotates stably.

[0031] The screws 74 can be any number, but two are preferred. The turntable 4 has several shaft holes corresponding one-to-one with the rotating seat 71. The rotating seat 71 passes through the shaft holes. The bearing 72 and the retaining ring 73 are coaxially sleeved on the outside of the rotating seat 71. The bearing 72 is also mounted on the turntable 4 and is pressed against the outer ring by screws 74 for positioning. That is, the inner ring of the bearing 72 mates with the rotating seat 71, and the outer ring mates with the shaft hole of the turntable 4. The retaining ring 73 is engaged at the lower end of the rotating seat 71 and contacts the lower end face of the turntable 4 to prevent loosening.

[0032] In one embodiment, the rotary detection device further includes a first reducer 2 and a second reducer 10. The first motor 1 drives the rotary table 4 to rotate via the first reducer 2, and the second motor 9 drives the rotating wheel 5 to rotate via the second reducer 10. The motor speed can be adjusted via the reducers.

[0033] In one embodiment, the rotary detection device further includes a position detection unit 14, which includes a position sensor and a sensing plate. The position sensor is connected to the fixed part of the second motor 9, and the sensing plate is connected to the rotating part of the second motor 9. The position detection unit 14 is used for limiting the movement of the second motor 9, such as stopping the movement when the rotating seat 71 completes a full revolution, thereby improving detection efficiency.

[0034] In one embodiment, the rotary detection device further includes a conductive slip ring 13, which is coaxially disposed on the rotary table 4 and electrically connected to the second motor 9 and the position detection unit 14.

[0035] In one embodiment, the rotary detection device further includes a connecting seat 12, which is connected to the rotating part of the first motor 1 and the rotary table 4 respectively, and a conductive slip ring 13 is built into the connecting seat 12.

[0036] The conductive slip ring 13 can be installed directly or indirectly at the rotation center of the turntable 4 through the connecting seat 12 to connect the wires of various electrical components, ensuring that the transmission of power and signals is not affected by continuous rotation.

[0037] In one embodiment, there are eight workpiece detection units 7, which are evenly distributed circumferentially on the turntable 4. The specific number and position can be adjusted according to actual needs.

[0038] In one embodiment, the rotary inspection device further includes a first mounting base 3. The first motor 1 is mounted on an external device via the first mounting base 3. The external device includes a frame and at least one camera. Both the first mounting base 3 and the camera are connected to the frame. The camera is used to capture images of the workpiece 11 to be inspected in the workpiece inspection unit 7. For example, cameras can be arranged above and below the workpiece inspection unit 7 at the corresponding workstation to achieve image acquisition of the workpiece 11 for inspection.

[0039] In one embodiment, both the first motor 1 and the second motor 9 are stepper motors. For example, the first motor 1 is a 57-stepper motor, and the second motor 9 is a 42-stepper motor. The specific configuration can be adjusted according to actual needs.

[0040] Working principle:

[0041] During operation, the first motor 1 drives the turntable 4 to rotate via the first reducer 2, enabling station rotation. When connected to the imaging station, the second motor 9 drives the rotating wheel 5 to rotate via the second reducer 10. The rotating wheel 5 and the workpiece detection unit 7 are connected by a belt 6, enabling the rotation of all stations. Images are then captured by a camera to obtain images from different directions. This device can also be used for lens cleaning and has a wide range of applications.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely specific and detailed examples of the embodiments described in this application, and should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
