[0002] Based on the folding accuracy requirements of folding screen mobile phones, it is necessary to detect the folding screen rotating shaft after machine or manual assembly to timely discover quality defects caused by processing or assembly.

[0003] In the prior art, usually, a clamping fixture is manually used in combination with a two-dimensional or three-dimensional measuring instrument to detect the actual rotation angle of the folding screen rotating shaft. In this process, since the angles of the upper and lower parts of the rotating shaft cannot be measured simultaneously, not only does it involve repeated clamping, increasing the detection error, but also the measurement process is quite cumbersome. Moreover, it cannot automatically identify the measurement and requires manual identification and data comparison, resulting in manual judgment errors and low work efficiency. In addition, the accuracy and timeliness of the measurement data cannot be guaranteed. Content of the Utility Model

[0004] To solve the above problems, the present application provides a folding screen rotating shaft synchronism detection device with a reasonable structure, so as to realize the synchronism detection of the rotating shaft under one clamping, which is convenient to operate, has good practicability, and effectively guarantees the accuracy and timeliness of data.

[0011] The fixed plate is fixedly installed relative to the support seat. A moving plate is arranged in parallel on the side of the fixed plate. A connecting rod vertically installed on the side of the moving plate passes through the fixed plate, and an elastic member is sleeved on the connecting rod to drive the moving plate to fit towards the fixed plate.

[0012] The fixed clamping mechanism includes a back plate arranged vertically. A clamping plate is installed on one side of the back plate. A static clamping block is installed at the lower part of the side of the clamping plate. A clamping cylinder is installed on the other side of the back plate.

The moving clamping block and the static clamping block cooperate to clamp the upper and lower ends of the product.

[0013] A convex pin for product positioning and fitting is installed on the side of the clamping plate; a sensor and a suction cup are also installed on the clamping plate.

[0014] The bottom end of the back plate is installed on the second adjusting plate. The second adjusting plate is installed on the first adjusting plate.

Long holes are arranged on the first adjusting plate and the second adjusting plate in a vertically intersecting manner in the horizontal direction. After an external fastener passes through the long holes, the first adjusting plate or the second adjusting plate is locked and fixed to the corresponding support or the first adjusting plate.

[0015] A through hole is formed through the rotating table and the working platform up and down. A second CCD camera located below the working platform takes pictures of the product upward through the through hole; a transparent plate is installed at the through hole.

[0016] A support assembly is installed through the working platform up and down. A first CCD camera and a second CCD camera are respectively installed on the support assemblies above and below the working platform, and light sources corresponding to the first CCD camera and the second CCD camera are respectively installed.

The elasticity of the clamping mechanism absorbs the inconsistency between the upper and lower parts of the product during rotation, and the upper and lower cameras are respectively used for angle detection after rotation;

[0022] When placing the product towards the fixed clamping mechanism, when the sensor senses the product, it triggers the suction cup to adsorb the product, and then the clamping cylinder works to clamp the product and release the vacuum adsorption; through the setting of vacuum adsorption, it can effectively prevent the clamping cylinder from clamping the hand and causing injury when placing the product;

[0035] The following combines with the attached drawings to illustrate the specific embodiments of the present utility model

[0036] As Figure 1 shown, a folding screen rotation shaft synchronism detection device of this embodiment includes a working platform 1. A rotating table 7 is installed on the working platform 1. A fixed clamping mechanism 6 is installed on the working platform 1 outside the side of the rotating table 7. A follower clamping mechanism 3 that rotates therewith is installed on the rotating table 7. The fixed clamping mechanism 6 and the follower clamping mechanism 3 respectively clamp the left and right parts of the product 10 that rotate relative to each other along the vertical axis; It also includes a first CCD camera 5 and a second CCD camera 8 that are arranged vertically opposite above and below the product 10

[0037] During detection, the rotating table 7 rotates a preset angle. The follower clamping mechanism 3 drives the first plate group 11 clamped on the product 10 to rotate with the rotating table 7. The second plate group 12 rotatably installed on the product 10 with the first plate group 11 is fixed by the fixed clamping mechanism 6. After the rotating table 7 rotates, the first CCD camera 5 and the second CCD camera 8 respectively capture the actual angle data of the upper and lower parts from above and below, obtain the angle error value, and can compare the angle data with the preset value, so as to realize the synchronism detection of the rotation shaft under one-time clamping

[0038] The follower clamping mechanism 3 is a non-powered elastic clamping mechanism, and further includes an unlocking mechanism 2. The unlocking mechanism 2 unlocks the clamping state of the follower clamping mechanism 3 to facilitate the loading or unloading of the product 10

[0039] In this embodiment, the follow - up clamping mechanism 3 adopts an elastic clamping mechanism. While effectively ensuring the stable clamping of the product 10, it can smoothly rotate synchronously with the rotation of the rotating table 7. The elasticity of the clamping mechanism absorbs the inconsistency between the upper and lower parts of the product 10 during rotation, and after rotation, the upper and lower cameras are respectively used for angle detection.

[0040] As Figure 3 shown, the structure of the follow - up clamping mechanism 3 is as follows: It includes a vertical plate 31 installed on the rotating part 72 of the rotating table 7. A support seat 33 is installed on the side of the vertical plate 31 through a Z - direction slide 32. A clamping assembly 34 is installed on the side of the support seat 33. The clamping assembly 34 includes a fixed plate 343 and a moving plate 344 that approach each other under the action of an elastic member 342, as Figure 4 shown;

[0041] The unlocking mechanism 2 includes a horizontally arranged unlocking cylinder 22, and the output end of the unlocking cylinder 22 is vertically facing the extension plate 345 of the moving plate 344.

[0042] In this embodiment, the fixed plate 343 and the moving plate 344 in the follow - up clamping mechanism 3 are elastically attached to each other under the elastic action of the elastic member 342 to clamp the product 10; when the unlocking mechanism 2 works, the action of the unlocking cylinder 22 applies a force to the extension plate 345, overcoming the elastic force of the elastic member 342, so that the moving plate 344 moves away from the fixed plate 343, thereby releasing the elastic clamping between the fixed plate 343 and the moving plate 344.

[0043] In this embodiment, the unlocking cylinder 22 can be installed and fixed on the working platform 1 through a support plate 21, or the support plate 21 can be fixedly installed on the fixed seat 71 of the rotating table 7.

[0044] In this embodiment, when the rotating table 7 is in the reset state, the output end of the unlocking cylinder 22 in the unlocking mechanism 2 is facing the extension plate 345 fixed to the moving plate 344 in the clamping assembly 34, which is convenient for the loading and unloading operations of the product 10 at the clamping assembly 34.

[0045] The fixed plate 343 is fixedly installed relative to the support seat 33. A moving plate 344 is arranged in parallel on the side of the fixed plate 343. A connecting rod 341 vertically installed on the side of the moving plate 344 passes through the fixed plate 343, and an elastic member 342 for driving the moving plate 344 to fit towards the fixed plate 343 is sleeved on the connecting rod 341.

[0046] In this embodiment, the elastic member 342 is sleeved on the connecting rod 341 after passing through the fixed plate 343, and an end plate for preventing the elastic member 342 from coming out is extended or assembled at the end of the connecting rod 341.

[0047] As Figure 2As shown in the figure, the fixed clamping mechanism 6 includes a vertically arranged back plate 64. On one side of the back plate 64, a clamping plate 63 is installed. At the lower part of the side of the clamping plate 63, a static clamping block 631 is equipped. On the other side of the back plate 64, a clamping cylinder 65 is installed. The upward output end of the clamping cylinder 65 is installed with a moving clamping block 66. The moving clamping block 66 and the static clamping block 631 cooperate to clamp the upper and lower ends of the product 10.

[0048] In this embodiment, the moving clamping block 66 and the static clamping block 631 jointly clamp the product 10 from the upper and lower sides via a V-shaped structure arranged oppositely, and the clamping is stable and reliable.

[0049] On the side of the clamping plate 63, a convex pin 67 for positioning and fitting the product 10 is installed. Coarse positioning during the feeding and placing of the product 10 is achieved via the convex pin 67; a sensor 69 and a suction cup 68 are also installed on the clamping plate 63.

[0050] When placing the product 10 towards the fixed clamping mechanism 6, when the sensor 69 senses the product 10, the suction cup 68 is triggered to adsorb the product 10. Then, the product 10 is clamped by the operation of the clamping cylinder 65, and the vacuum adsorption is released; through the setting of vacuum adsorption, it can effectively prevent the clamping cylinder 65 from clamping the hand and causing injury when placing the product 10.

[0051] The bottom end of the back plate 64 is installed on the second adjusting plate 62, the second adjusting plate 62 is installed on the first adjusting plate 61, and the first adjusting plate 61 is installed on the working platform 1 via the support 60; long holes are provided on the first adjusting plate 61 and the second adjusting plate 62 and are arranged perpendicular to each other in the horizontal direction. After an external fastener passes through the long hole, the first adjusting plate 61 or the second adjusting plate 62 is locked and fixed to the corresponding support 60 or the first adjusting plate 61; the relative position of the back plate 64 can be adjusted in the X and Y directions according to actual needs, so as to adjust the relative position of the product 10 relative to the rotating table 7 after clamping.

[0052] A through hole is provided through the rotating table 7 and the working platform 1 up and down. The second CCD camera 8 located below the working platform 1 takes pictures of the product 10 upward through the through hole, effectively realizing synchronous detection from below and above; a transparent plate 70 is installed at the through hole, which not only does not affect the camera's picture taking but also effectively prevents dust from falling.

[0053] In this embodiment, the rotating table 7 includes a fixed seat 71 fixedly installed with the working platform 1, and a rotating part 72 rotatably fitted on the fixed seat 71. The rotating part 72 is driven by a motor 73 to rotate relative to the fixed seat 71.

[0054] In this embodiment, the rotating table 7 can select a standard off-the-shelf component.

[0055] A support assembly 4 is installed on the upper and lower through working platform 1. A first CCD camera 5 and a second CCD camera 8 are respectively installed on the support assemblies 4 above and below the working platform 1, and light sources 40 corresponding to the first CCD camera 5 and the second CCD camera 8 respectively; thus, it can effectively ensure that the first CCD camera 5 and the second CCD camera 8 are directly opposite to each other above and below the rotation point of the product 10.

[0056] As Figure 5 shown, the structure of the support assembly 4 is: including two columns 41 installed through the upper and lower parts of the working platform 1. The upper and lower parts of the column 41 are respectively installed with a support plate 44 through a bushing seat 43. A first CCD camera 5 and a second CCD camera 8 are installed on the support plate 44 through an XY two-way adjustment slide 45; the lens of the first CCD camera 5 is arranged downward, and the lens of the second CCD camera 8 is arranged upward. It also includes light sources 40 corresponding to the first CCD camera 5 and the second CCD camera 8 respectively. The light sources 40 are supported on the two columns 41 through brackets 42.

[0057] In this embodiment, the bushing seat 43 is clamped and fixed around the column 41. By loosening the fastener, the bushing seat 43 can be driven to move up and down relative to the column 41 for adjustment. Tightening the fastener fixes the bushing seat 43 on the column 41; a connecting column 46 is installed between the two bushing seats 43 supported under the same support plate 44, which is convenient for realizing the synchronous up and down adjustment of the two bushing seats 43 on the corresponding columns 41.

[0058] The usage method of the utility model is as follows:

[0059] Loading: Place the second board group 12 of the product 10 at the clamping plate 63 of the fixed clamping mechanism 6. After the sensor 69 senses the product 10, the suction cup 68 works to adsorb the second board group 12 on the clamping plate 63. Then the clamping cylinder 65 works, driving the moving clamping block 66 to move downward, and combining with the lower static clamping block 631 to clamp and fix the second board group 12, and the suction cup 68 breaks the vacuum to release the adsorption; at the same time, the unlocking cylinder 22 in the unlocking mechanism 2 works, pushing the extension plate 345 to make the moving plate 344 away from the fixed plate 343, clamping the first board group 11 of the product 10 between the fixed plate 343 and the moving plate 344, and the unlocking mechanism 2 resets.

[0060] Detection: The rotating table 7 works, driving the first board group 11 in the product 10 to rotate with the rotating table 7 through the follow-up clamping mechanism 3. The first board group 11 rotates a preset angle relative to the second board group 12. Then the first CCD camera 5 and the second CCD camera 8 respectively obtain the actual rotation angle from above and below, compare to obtain the angle error value, and can compare the actual rotation angle with the preset rotation angle, so as to realize the synchronous detection of the rotating shaft under one clamping.

[0061] According to the actual detection requirements, in combination with the rotation of the rotary table 7, the folding screen rotating shaft can be opened or closed by a preset angle value to detect the actual deviation.

[0062] The utility model is simple to operate and realizes the synchronous detection of the rotating shaft under one-time clamping. It not only effectively simplifies the detection process, avoids the cumbersome process of repeated clamping and the error of repeated clamping, improves work efficiency, but also can effectively ensure the accuracy and timeliness of data, and has good practicability.
