Description

Technical Field

[0001] This application relates to the field of rubber product technology, and in particular to an improved rubber product appearance inspection device. Background Technology

[0002] Rubber, due to its excellent shock absorption, cushioning and tensile strength, can be made into rubber joints, which are used as connecting elements between key components. Rubber joints are usually concentric with different diameters, large at both ends and thin in the middle.

[0003] In related technologies, the appearance quality of rubber joints directly affects their performance and service life. Therefore, the produced rubber joints need to undergo a strict appearance inspection process to screen out defective products. Rubber appearance inspection agencies generally adopt machine vision solutions, using industrial cameras for two-dimensional planar inspection.

[0004] Existing rubber product appearance inspection equipment has the following problems: due to technical reasons, the machine's inspection mechanism is generally limited to a unidirectional or bidirectional inspection direction, resulting in relatively low inspection efficiency. Summary of the Invention

[0005] To improve the inspection efficiency of rubber joints, this application provides an improved rubber product appearance inspection device.

[0006] The improved rubber product appearance inspection device provided in this application adopts the following technical solution: An improved rubber product appearance inspection device includes: a worktable, a support component, a first inspection component, and a second inspection component. The support component is disposed on the worktable and is used to support a rubber joint. The first inspection component includes a first support frame and a first inspection camera. The first support frame is mounted on the worktable, and the first inspection camera is slidably disposed on the first support frame along the X / Y axis. The second inspection component is disposed at the rear end of the first inspection component. The first inspection component cooperates with the second inspection component to perform multi-directional inspection of the workpiece.

[0007] By adopting the above solution, compared with the traditional rubber product appearance inspection device which is limited to at most two inspection positions, the first inspection camera can slide on the first support frame to achieve multi-directional appearance inspection, thereby improving the appearance inspection efficiency of rubber joints.

[0008] Preferably, the first support frame includes a first support base, a support rod, and a cantilever. The support rod is horizontally arranged and vertically fixed to the side wall of the first support base. The cantilever is mounted on the support rod and is located above the load-bearing component. The cantilever is cross-shaped. Each of the four arms of the cantilever is provided with a first connecting block. The first connecting block is perpendicular to the cantilever. The arms of the cantilever are also provided with a sliding groove along their length. One end of the first connecting block is threaded to the sliding groove, and the other end of the first connecting block is connected to the first detection camera.

[0009] By adopting the above solution, the bolts passing between the first connecting block and the slide groove are loosened, the restriction on the first connecting block is released, and the first connecting block can drive the first detection camera to slide on the cantilever, thereby realizing the rapid adjustment and positioning of the first detection camera.

[0010] Preferably, one end of the support rod has a plurality of arc-shaped holes, which are arranged in a circle and have the centers of the arc-shaped holes coincide. Bolts pass through the arc-shaped holes to make the support rod and the cantilever threaded together.

[0011] By adopting the above scheme, the cross-shaped structure facilitates the cantilever's own force balance. Because the arc-shaped hole provides clearance for the fasteners, the cantilever can rotate at a certain angle during installation, thereby adjusting the initial position of the first detection camera.

[0012] Preferably, one end of the first connecting block is provided with a carrier block, the carrier block is rotatably supported on the first connecting block, and the first detection camera is supported on the carrier block.

[0013] By adopting the above solution, the bolts passing through the carrier block and the first connecting block are loosened, the restriction on the carrier block is removed, and the carrier block can drive the first detection camera to rotate and adjust the pitch angle of the first detection camera within a certain range.

[0014] Preferably, each of the four arms of the cantilever is provided with a scale along its own length.

[0015] By adopting the above scheme and quantifying the position information of the first inspection camera on the cantilever arm, the time required to adjust the focal length of the first inspection camera can be reduced before the inspection process begins, thereby indirectly improving inspection efficiency.

[0016] Preferably, the supporting component includes a rotary motor and a transparent turntable, the rotary motor is mounted on the worktable, and the transparent turntable is coaxially fixed with the output shaft of the rotary motor.

[0017] By adopting the above scheme, the rotary motor drives the transparent turntable to rotate at a constant speed of 360° around the output shaft. The rubber joint can be rotatably supported on the transparent turntable, and at the same time, it works with the first detection component and the second detection component to achieve multi-dimensional appearance quality inspection.

[0018] Preferably, the second detection component includes a second detection camera, a second support frame, and a second connecting block. The second support frame is disposed on the worktable, one end of the second connecting block is connected to the second detection camera, and the second connecting block is slidably disposed on the second support frame.

[0019] By adopting the above scheme, the detection end of the second detection camera can face the transparent turntable from top to bottom, and is responsible for detecting the appearance quality of the upper and lower surfaces of the rubber joint.

[0020] Preferably, the first detection component further includes a first detection lamp and a lighting lamp. The first connecting block is provided in several groups. The first detection lamp and the first detection camera are respectively installed on two groups of the first connecting blocks. The lighting lamp is fixedly connected to the side wall of the first support base. The lighting lamp is located below the transparent turntable and the light source faces upward.

[0021] By adopting the above scheme, the lighting lamp is responsible for reducing the shadow in the rubber joint detection area, and the first detection lamp is responsible for reducing the occurrence of reflection interference with the detection camera. The two light sources are used in combination to help improve the detection accuracy of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The first and second detection components work together to achieve a multi-faceted machine vision inspection solution, which improves the appearance inspection efficiency of the device; 2. The detection position and corresponding focal length of the first detection camera can be quickly adjusted before the detection process begins by using the scale set on the cantilever and the cantilever support arm, saving working time and indirectly improving the working efficiency of the device; 3. The use of both a spotlight and a detection light improves the detection accuracy of the device. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses an improved appearance inspection device for rubber products. (Refer to...) Figure 1-2 An improved rubber product appearance inspection device includes a workbench 1, a support component 2, a first inspection component 3, and a second inspection component 4. The support component 2 is disposed on the workbench 1 and is used to support the rubber joint 5. The first inspection component 3 is disposed on the workbench 1, and the second inspection component 4 is disposed at the rear end of the first inspection component 3. The first inspection component 3 cooperates with the second inspection component 4 to perform multi-directional inspection of the workpiece.

[0028] Specifically, the supporting component 2 includes a rotary motor 21 and a transparent turntable 22. The rotary motor 21 is installed inside the workbench 1, and the output shaft of the rotary motor 21 extends through the upper surface of the workbench 1. The transparent turntable 22 is fixed coaxially with the output shaft of the rotary motor 21 and is horizontally positioned. The rotary motor 21 drives the transparent turntable 22 to rotate 360° at a uniform speed around the output shaft. The rubber joints 5 are arranged on one side of the edge of the upper surface of the transparent turntable 22 and rotate with the transparent turntable 22, thereby reducing the detection blind zone of the device.

[0029] Correspondingly, the first detection component 3 includes a first support frame 34 and a first detection camera 31. The first support frame 34 is mounted on the worktable 1 and located on one side of the transparent turntable 22. The first detection camera 31 is slidably mounted on the first support frame 34 along the X / Y axis direction, and the detection end of the first detection camera 31 faces the upper surface of the transparent turntable 22.

[0030] Specifically, the first support frame 34 includes a first support base 341, a support rod, and a cantilever 344. The first support base 341 is installed on the upper surface of the workbench 1 and is located outside the transparent turntable 22. The support rod is horizontally set and vertically fixed to the side wall of the first support base 341. The cantilever 344 is installed on the support rod and is located above the transparent turntable 22. The cantilever 344 has a cross-shaped structure and is horizontally set. Each of the four arms of the cantilever 344 is provided with a first connecting block 346. The first connecting block 346 is perpendicular to the cantilever 344. The arms of the cantilever 344 are also provided with a sliding groove 345 along their own length direction. One end of the first connecting block 346 is threadedly connected to the sliding groove 345, and the other end of the first connecting block 346 is connected to the first detection camera 31.

[0031] Therefore, the first detection camera 31 can be displaced along the slide groove 345. By loosening the bolt between the first connecting block 346 and the slide groove 345, the bolt's restriction on the first connecting block 346 is released, allowing the first connecting block 346 to drive the first detection camera 31 to slide on the cantilever 344. Correspondingly, by tightening the bolt between the first detection camera 31 and the slide groove 345 again, the first connecting block 346, carrying the first detection camera 31, is fixed on the cantilever 344, realizing flexible adjustment of the detection position of the first detection camera 31. Compared with traditional rubber product appearance inspection devices that are limited to at most two fixed detection positions, this detection device can cover multi-directional detection areas, improving the detection efficiency of the rubber joint 5.

[0032] Furthermore, a carrier block 347 is provided at one end of the first connecting block 346. The carrier block 347 is threadedly connected to one end of the first connecting block 346. The first detection camera 31 is supported on the carrier block 347. A bent hole 348 is provided at one end of the carrier block 347. The bent hole 348 provides clearance for the fasteners between the carrier block 347 and the detection camera. By loosening the bolts between the carrier block 347 and the first connecting block 346, the carrier block 347 can move a certain distance along the inner wall of the bent hole 348. After retightening the bolts, the carrier block 347 is fixed again, and the pitch angle of the first detection camera 31 can be adjusted, thereby improving the detection range.

[0033] Furthermore, the cross-shaped structure of the cantilever 344 facilitates the balancing of the forces on the four arms, reducing the occurrence of excessive stress concentration.

[0034] Meanwhile, one end of the support rod is provided with several arc-shaped holes 343. In this example, there are four arc-shaped holes 343 in total. The four arc-shaped holes 343 are arranged in a circle and the centers of the four arc-shaped holes 343 coincide. The bolt passes through the arc-shaped holes 343 to make the support rod and the cantilever 344 threadedly connected. Because the arc-shaped holes 343 have a clearance effect on the fasteners, the cantilever 344 can rotate a certain angle relative to the center of the arc-shaped holes 343 during installation, thereby adjusting the detection position of the first detection camera 31 in the horizontal direction.

[0035] In addition, each of the four arms of the cantilever 344 is provided with a scale 349 (not shown in the figure) along its own length direction. The scale 349 is bonded and fixed to the outside of the slide groove 345 and is set parallel to the cantilever 344. In this embodiment, the scale 349 can provide standard accuracy in the range of 0-200mm. By quantifying the position information of the first detection camera 31 on the arm of the cantilever 344, the time for adjusting the focal length of the first detection camera 31 can be reduced before the detection process begins, thereby indirectly improving the detection efficiency.

[0036] On the other hand, the second detection component 4 includes a second detection camera 43, a second support frame 41, and a second connecting block 42. The second support frame 41 is disposed on the workbench 1. One end of the second connecting block 42 is connected to the second detection camera 43. The second connecting block 42 is slidably disposed on the second support frame 41 in the vertical direction. The second detection camera 43 further expands the detection range by moving up and down on the second support frame 41. The second detection camera 43 can be responsible for detecting the appearance quality of the upper and lower surfaces of the rubber joint 5.

[0037] On the other hand, the first detection component 3 also includes a first detection lamp 32 and a lighting lamp 33. In this embodiment, there are four sets of first connecting blocks 346, with two first connecting blocks 346 in each set. The four sets of first connecting blocks 346 are respectively set on the four arms of the cantilever 344. The first detection lamp 32 and the first detection camera 31 are respectively installed on the two first connecting blocks 346 in the same set. The first detection lamp 32 is located in front of and higher than the first detection camera 31 in the horizontal direction. The lighting lamp 33 is fixedly connected to the side wall of the first support 341 and is located below the transparent turntable 22. The light source of the lighting lamp 33 faces upward.

[0038] Furthermore, the second detection component 4 also includes a second detection light 44. In this embodiment, the second support frame 41 is provided in three sets. One set of the second support frame 41 is used to support the second detection camera 43, and the other two sets of the second support frame 41 are slidably provided with the second detection light 44.

[0039] Furthermore, in this embodiment, the light sources emitted by the first detection lamp 32 and the illumination lamp 33 are both white. The illumination lamp 33 is responsible for initially reducing the shadow area on the rubber joint 5. The cross-section of the first detection lamp 32 is U-shaped. The first detection lamp 32 is located in front of and above the first detection camera 31 in the horizontal direction. The first detection lamp 32 can reduce the interference of reflections in the device on the final imaging of the first detection camera 31.

[0040] Furthermore, the second detection lamp 44 emits a blue light source, which is responsible for reflecting and distinguishing possible impurities, cracks and other defects on the rubber joint 5. The two light sources are used together to help improve the detection accuracy of the device.

[0041] The implementation principle of an improved rubber product appearance inspection device according to an embodiment of this application is as follows: the detection position of the component that plays the main detection function can be adjusted through the mechanical structure in the device, thereby expanding the detection angle, covering a multi-directional detection area, and improving the detection efficiency of rubber joints.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
