Description

Technical Field

[0001] This invention relates to the field of fixture technology for screen visual inspection, and specifically to a continuous flexible fixture for screen visual inspection. Background Technology

[0002] With the rapid development of electronic technology, electronic products have gradually become an indispensable part of daily life, especially smart products such as smartphones and tablets. These products all use screens. During processing and transportation, the screen surface is prone to appearance defects that affect product quality, such as stress marks, dents, dents, scratches, etc. Therefore, inspection equipment has emerged to collect images and identify defects one by one.

[0003] During this process, the screen needs to be clamped onto the inspection equipment. Traditional rigid clamping tools are prone to causing secondary damage to the screen, and the rigid clamping tools can also cause the screen to deform under force during the clamping process, which will also affect the image acquisition accuracy during visual inspection.

[0004] For the clamping and unloading parts in screen visual inspection, we designed a flexible unloading process and a flexible clamping device to meet the appearance inspection needs of screens of different sizes. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a continuous flexible fixture for screen visual inspection.

[0006] The technical solution adopted by this invention to solve its technical problem is: a continuous flexible fixture for screen visual inspection, comprising a detection component, a detection box, an unloading component, a second cylinder, a first cylinder, a conveying component, a clamping component, a fixed platform, a reference plate, and a fixed frame as the main body; the detection component, the unloading component, and the conveying component are all mounted on the upper surface of the detection box, and the detection component and the conveying component are perpendicular to each other at a 90° angle; the clamping component is mounted on the conveying component, and the conveying component drives the clamping component to move horizontally; the clamping component has a movable seat at the bottom and a fixed platform installed in the middle, and the fixed platform has a fixed frame, a first-stage flexible end plate, a second-stage flexible end plate, a third-stage flexible end plate, and three support columns; the front end of the first-stage flexible end plate has a fixed shaft fixedly connected to it, and the fixed shaft passes through the fixed frame and can rotate. The primary, secondary, and tertiary flexible end plates are respectively provided with a movable shaft, a transition arc segment, a limiting edge, and a stopping edge between adjacent plates. The transition arc segment allows all three plates to rotate and unfold around the movable shaft, while the limiting and stopping edges restrict their retracted state. The fixed frame is provided with an auxiliary slope, the arc segment of which is greater than a quarter circle, facilitating the adjustment of the angle and direction of the primary, secondary, and tertiary flexible end plates as they slide against the auxiliary slope. The reference plate is provided with a positioning hole sleeve, a protective plate, and an open end cavity, with the open end cavity facing the fixed frame. The unloading assembly can extend into the bottom of the reference plate to lift and move it.

[0007] In this embodiment, the three support columns are arranged in a right-angled triangle shape on the surface of the fixed platform, so that the three support columns can define a plane, and the top of the support columns is provided with a positioning ball head that is fixedly connected to the support column.

[0008] In this embodiment, the positioning ball head is spherical, so that when the positioning hole sleeve comes into contact with the positioning ball head, it can quickly fit and position itself. The positioning ball head is magnetic, and during the contact between the positioning hole sleeve and the positioning ball head, the magnetic positioning ball head guides the placement of the reference plate in a directional manner.

[0009] In this embodiment, after the positioning hole sleeve and the positioning ball head come into contact and are attracted together under the action of magnetic force, the positioning hole sleeve and the positioning ball head can be separated after the reference plate is subjected to a thrust greater than 4.5N on the horizontal plane.

[0010] In this embodiment, the positioning hole sleeve is annularly embedded in the reference plate, that is, the positioning hole sleeve and the reference plate are interference fit, and the material of the positioning hole sleeve can be attracted to the positioning ball head.

[0011] In this embodiment, the primary flexible end plate, the secondary flexible end plate, and the tertiary flexible end plate are made of composite materials, that is, 4.5%-10% cotton and silk are added to rubber to enhance its bending resistance and fatigue resistance.

[0012] In this embodiment, the first-level flexible end plate, the second-level flexible end plate, and the third-level flexible end plate are respectively provided with movable magnetic strips that fit against the inner surfaces of the first-level flexible end plate, the second-level flexible end plate, and the fixed frame is provided with fixed magnetic strips. The attraction between the movable magnetic strips and the fixed magnetic strips causes the first-level flexible end plate, the second-level flexible end plate, and the third-level flexible end plate to unfold and fit against the side of the fixed frame, thereby increasing the friction of the first-level flexible end plate, the second-level flexible end plate, and the third-level flexible end plate when moving on the auxiliary ramp.

[0013] In this embodiment, the protective plate is located at the opposite end of the opening through the cavity, and the vertical surface of the protective plate is in the shape of a right triangle, so that the protective plate blocks the side of the screen while facilitating the screen to be moved out of the reference plate in the vertical direction.

[0014] In this embodiment, the unloading assembly is provided with a support frame, a second cylinder, a push arm, a lifting arm, a guide rail, and a first cylinder. The lifting arm is connected to the first cylinder via the guide rail. The second cylinder is connected to the push arm and is fixed to the surface of the detection box via the support frame.

[0015] The beneficial effects of this invention are: during the contact between the positioning hole sleeve and the positioning ball head, the magnetic positioning ball head guides the placement of the reference plate in a specific direction; and during the process of the unloading assembly extending into the bottom of the reference plate to lift and move it, the reference plate is flexibly separated, making operation simple; by utilizing the characteristics of the composite materials of the first-level flexible end plate, the second-level flexible end plate, and the third-level flexible end plate, as well as the different states of convergence and aggregation, screens of different sizes are pressed against the reference plate, which is a flexible clamping method that can adapt to screen sizes with a large range. The design is ingenious and easy to use. Attached Figure Description

[0028] To make the technical solution of the present invention clearer, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] like Figure 1-11As shown, the continuous flexible fixture for screen visual inspection of the present invention comprises a detection component 1, a detection box 2, an unloading component 3, a second cylinder 32, a first cylinder 36, a conveying component 4, a clamping component 5, a fixed platform 56, a reference plate 7, and a fixed frame 9 as its main components. The detection component 1, the unloading component 3, and the conveying component 4 are all mounted on the upper surface of the detection box 2, and the detection component 1 and the conveying component 4 are perpendicular to each other at a 90° angle. The clamping component 5 is mounted on the conveying component 4, and the conveying component 4 drives the clamping component 5 to move horizontally. The clamping component 5 has a movable seat 41 at its bottom and a fixed platform 56 in the middle. The fixed platform 56 is provided with a fixed frame 9, a primary flexible stop plate 51, a secondary flexible stop plate 52, a tertiary flexible stop plate 53, and three support columns 101. The front end of the primary flexible stop plate 51 is provided with a fixed shaft 8 fixedly connected to it. The fixed shaft 8 passes through the fixed frame 9 and can rotate. The primary flexible stop plate 51... The primary flexible end plate 52 and the tertiary flexible end plate 53 are respectively provided with a movable shaft 6, a transition arc segment 61, a limiting edge 62, and a stopping edge 63 between adjacent parts. The transition arc segment 61 allows the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53 to rotate and unfold around the movable shaft 6. The limiting edge 62 and the stopping edge 63 restrict the retracted state of the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53. The frame 9 is provided with an auxiliary slope 91, and the arc of the auxiliary slope 91 is greater than a quarter circle arc, so as to facilitate the change of angle and direction during the sliding of the first-level flexible end plate 51, the second-level flexible end plate 52 and the third-level flexible end plate 53 against the auxiliary slope 91; the reference plate 7 is provided with a positioning hole sleeve 73, a guard plate 71 and an open end cavity 72, and the open end cavity 72 faces the side of the fixed frame 9; the unloading assembly 3 can extend into the bottom of the reference plate 7 to lift and move the reference plate 7.

[0030] In this embodiment, the three support columns 101 are arranged in a right-angled triangle shape on the surface of the fixed platform 56, so that the three support columns 101 can define a plane, and the top of the support column 101 is provided with a positioning ball head 102 fixedly connected to the support column 101.

[0031] In this embodiment, the positioning ball head 102 is spherical, so that when the positioning hole sleeve 73 comes into contact with the positioning ball head 102, it can quickly fit and position itself. The positioning ball head 102 is magnetic, and during the contact between the positioning hole sleeve 73 and the positioning ball head 102, the magnetic positioning ball head 102 guides the placement of the reference plate 7 in a directional manner.

[0032] In this embodiment, after the positioning hole sleeve 73 and the positioning ball head 102 come into contact and are attracted together under the action of magnetic force, the positioning hole sleeve 73 and the positioning ball head 102 can be separated after the reference plate 7 is subjected to a thrust greater than 4.5N on the horizontal plane.

[0033] In this embodiment, the positioning hole sleeve 73 is annularly embedded in the reference plate 7, that is, the positioning hole sleeve 73 and the reference plate 7 are interference fit, and the material of the positioning hole sleeve 73 can be attracted to the positioning ball head 102.

[0034] In this embodiment, the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53 are made of composite materials, that is, 4.5%-10% cotton and silk are added to rubber to enhance its bending resistance and fatigue resistance.

[0035] In this embodiment, the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53 are respectively provided with movable magnetic strips 54 that fit against the inner surfaces of the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53, and the fixing frame 9 is provided with fixed magnetic strips 55. The attraction between the movable magnetic strips 54 and the fixed magnetic strips 55 causes the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53 to unfold and fit against the side of the fixing frame 9, thereby increasing the friction of the primary flexible end plate 51, the secondary flexible end plate 52, and the tertiary flexible end plate 53 when they move on the auxiliary ramp 91.

[0036] In this embodiment, the protective plate 71 is located opposite the opening through the end cavity 72. The vertical surface of the protective plate 71 is in the shape of a right triangle, so that the protective plate 71 blocks the side of the screen while facilitating the screen to move out of the reference plate 7 in the vertical direction.

[0037] In this embodiment, the unloading assembly 3 is provided with a support frame 31, a second cylinder 32, a push arm 33, a lifting arm 34, a guide rail 35 and a first cylinder 36. The lifting arm 34 is connected to the first cylinder 36 through the guide rail 35. The second cylinder 32 is connected to the push arm 33 and is fixed to the surface of the detection box 2 through the support frame 31.

[0038] When in use, the reference plate 7 needs to be placed on the fixed platform 56. During this process, the positioning hole sleeve 73 contacts the positioning ball head 102, and the magnetic positioning ball head 102 guides the placement of the reference plate 7 in a directional manner. The three support columns 101 support the bottom of the reference plate 7 in a right-angled triangle shape.

[0039] Furthermore, the first-level flexible end plate 51, the second-level flexible end plate 52, and the third-level flexible end plate 53 are initially in an unfolded state. After the screen is placed on the reference plate 7, the third-level flexible end plate 53 is pushed. Next, the first-level flexible end plate 51, the second-level flexible end plate 52, and the third-level flexible end plate 53 change their angle and direction as they slide against the auxiliary slope 91. During this process, the first-level flexible end plate 51, the second-level flexible end plate 52, and the third-level flexible end plate 53 form a planar spiral state and press against the screen. The characteristics of the composite material and the different states of contraction and aggregation are used to press screens of different sizes against the reference plate 7, thereby adapting to screen sizes with a large range. The design is ingenious and easy to use.

[0040] Furthermore, after the visual inspection component 1 completes the inspection, it moves to the unloading component 3. At this time, the unloading component 3 extends into the bottom of the reference plate 7 and lifts the reference plate 7. During the movement, the reference plate 7 is flexibly separated from the clamping component 5, thereby reducing the vibration generated by the screen and making the operation simple.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
