Description

Technical Field

[0001] This invention relates to the field of display screen inspection, and more particularly to a visual inspection device for automatic verification of mobile phone displays. Background Art

[0002] With the development of technology, the network and communication have become increasingly advanced, and mobile phones have become more and more popular, becoming one of the indispensable communication tools in people's production and life. The whole-machine testing of mobile phones in the production process involves hardware testing and software testing. At the same time, it is also necessary to automatically verify the visual communication part of the mobile phone, namely the screen, especially to test the touch screen effect.

[0003] For example, Chinese Patent Application No. 202110221001.9 discloses an automatic verification and visual inspection device and method for mobile phone displays, including a support frame; a cylindrical turntable is rotatably connected to the support frame, one side of the turntable is connected to a motor via a rotating shaft, a positioning cavity with a rectangular cross-section is opened on the side wall of the turntable, the opening of the positioning cavity gradually increases from the inside to the outside, a visual inspection instrument is installed at the bottom of the positioning cavity, a robotic arm is provided at the top of the middle of the turntable, and a suction cup made of elastic rubber is provided at the bottom of the robotic arm. This invention can automatically verify and accurately position the mobile phone, greatly improving the accuracy of mobile phone displays during inspection. At the same time, the device has a simple structure, only requiring the robotic arm to automatically adjust its own position during the rotation of the mobile phone display, preventing the mobile phone from having low inspection efficiency due to its own position adjustment.

[0004] like Figure 13 The image shows a foldable screen phone in the prior art. The phone screen can be folded and unfolded. The foldable screen phone has an inner screen and an outer screen. However, the prior art solutions represented by the above patent, when dealing with this kind of phone with two screens in different positions, not only do they require the frequent opening and closing of the inner and outer screens using specially designed clamps, but they also need to be transferred between different verification mechanisms to complete the verification of the two screens. This results in a discontinuous testing process and greatly reduces the efficiency of automatic verification of this type of foldable screen phone. Summary of the Invention

[0018] The beneficial effects of the present invention are:

[0019] (1) The present invention, through the combined action of the transmission mechanism, clamping component, unfolding component and touch detection component, can quickly verify the inner and outer screens of the foldable screen phone. It does not require frequent opening and closing of the foldable screen phone, nor does it require transfer between different verification mechanisms, which greatly improves the automatic verification efficiency of this type of foldable screen phone. Specifically, the transmission mechanism transmits the foldable screen phone, the clamping component holds the foldable screen phone, the unfolding component unfolds the foldable screen phone, and the touch detection component detects the inner and outer screens of the foldable screen phone, which facilitates the use of the device.

[0020] (2) In this invention, the rotating drive a drives the foldable screen phone to rotate 90°, the linear drive a drives the inclined plate, the rotating frame and the L-shaped plate to move to one side of the clamping assembly, the rotating drive b drives the rotating frame and the L-shaped plate to rotate to a horizontal state (the L-shaped plate contacts the top of the foldable screen phone), the rotating drive c rotates and pulls the rope, causing the inverted clamp to clamp the upper part of the foldable screen phone; it drives the rotating frame and the L-shaped plate to rotate outward by 180°, thereby unfolding the foldable screen phone, which facilitates the subsequent touch detection assembly to detect the inner screen.

[0021] (3) By driving the sliding ring to slide in the sliding groove (rotating along the 0 axis), driving the rotating ring to rotate (rotating along the P axis), and driving the sliding rod b to move along the M axis, the present invention can realize the free movement of the touch rod within a certain space range, and thus can drag the icons on the screen at will, which facilitates the detection of the screen.

[0022] (4) This invention transmits the foldable screen phone to the flip plate, drives the rotating rod a to rotate, drives the connecting rod to rotate inward, drives the clamping wheel to clamp the two sides of the foldable screen phone from both sides, drives the rotating rod c to rotate through the motor, drives the clamping wheel to rotate through the belt c, and drives the foldable screen phone to move forward to the center of the flip plate; the flip plate stops rotating, and the foldable screen phone is positioned; that is to say, the driving clamping part can achieve the effect of the foldable screen phone being stationary (the clamping wheel does not rotate), and can also achieve the downward transmission of the foldable screen phone (the clamping wheel rotates).

[0023] (5) In this invention, the rotating drive component b drives the rotating frame and L-shaped plate to rotate inward by 90° through the belt b, thereby driving one end of the foldable screen phone to rotate to a vertical position. The flip plate is driven to rotate by 90° through the motor, thereby driving the other end of the foldable screen phone to rotate to a vertical position. The clamping wheel is driven to rotate through the belt c, thereby realizing the downward transmission of the foldable screen phone into the pipe.

[0024] (6) The present invention uses a conveyor belt to transport a foldable screen phone into the channel. The rotating block is driven by the rotating drive e to rotate 180° along the Y-axis, which can adjust the outer screen of the foldable screen phone to face upward. At the same time, when the foldable screen phone is transported to the flip plate, the rotating drive a drives the flip plate to rotate 0° or 180° to adjust the position of the foldable screen phone, which is convenient for subsequent screen detection.

[0025] (7) In this invention, the rotating drive g drives the rotating sleeve to rotate 180° via the belt d, thereby rotating the touch rod into the groove and rotating the detection rod out. The linear drive b drives the detection rod to move downward, so that the detection rod contacts the inner screen. The detection rod is equipped with a position sensor. Then, by rotating along the O axis and the P axis, the positions of multiple points are collected on both sides of the inner screen, thereby detecting the inner screen angle of the foldable screen phone.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0051] Example 1

[0052] like Figure 13 The image shows a foldable screen phone in the prior art, which has an outer screen and an inner screen. It has a folding function, and both the outer screen and the inner screen can be used for touch display. It is highly operable and therefore very popular with consumers.

[0053] like Figures 1 to 12 As shown, this embodiment provides a visual inspection device for automatic verification of mobile phone display screens, including a frame 1, a transmission mechanism 2, and a foldable screen mobile phone transmitted by the transmission mechanism 2 mounted on the frame 1. It should be noted that the foldable screen mobile phone is in a folded state when the transmission mechanism 2 is transmitting the phone. The display screen detection mechanism 3 mounted on the transmission mechanism 2 detects the inner screen and outer screen of the foldable screen mobile phone respectively.

[0054] like Figure 2 Figure 8 As shown, the display detection mechanism 3 includes: a clamping component 31, which is installed in the transmission mechanism 2 to clamp the foldable screen phone; an unfolding component 32, which unfolds the inner screen of the foldable screen phone; and a touch detection component 33, which detects the inner and outer screens of the foldable screen phone.

[0055] In this embodiment, the present invention, through the combined action of the transmission mechanism 2, the clamping component 31, the unfolding component 32, and the touch detection component 33, can quickly verify the two screens inside and outside the foldable screen of the foldable phone. It does not require frequent opening and closing of the foldable screen phone, nor does it require transfer between different verification mechanisms, which greatly improves the automatic verification efficiency of this type of foldable screen phone.

[0056] like Figure 4 and Figure 5 As shown, the clamping assembly 31 includes: a base plate 311, which is mounted on the frame 1; a rotation drive a312, which is mounted on the base plate 311; a working plate 313, which is mounted on the output end of the rotation drive a312; a flip plate 314, which is rotatably mounted on the working plate 313; and a drive clamping part 315, which is mounted on the flip plate 314 and is used to drive the foldable screen phone to move or remain stationary.

[0057] Furthermore, such as Figure 7 and Figure 8 As shown, the drive clamping part 315 includes: a protective cover 3151, which is installed on both sides of the flip plate 314, and has a clearance groove 31511; a rotating rod a 3152, with multiple sets of rotating rods a 3152 installed inside the protective cover 3151; a connecting rod 3153, which is installed on the rotating rod a 3152; a clamping wheel 3154, which is installed on one end of the connecting rod 3153; a rotating rod b 3155, which is installed on the clamping wheel 3154; and a rotating rod c 3156, which is rotatably disposed inside the rotating rod a 3152. The rotating rod c 3156 and the rotating rod b 3155 are connected by a belt c 3157, and the multiple sets of rotating rods a 3152 are synchronously driven by a sprocket and chain, and the multiple sets of rotating rods c 3156 are synchronously driven by a sprocket and chain.

[0058] In this embodiment, as Figure 14 As shown, the transmission mechanism 2 transmits the foldable screen phone to the flip plate 314. The motor drives the rotating rod a3152 to rotate, which in turn drives the connecting rod 3153 to rotate inward, causing the clamping wheels 3154 to clamp the two sides of the foldable screen phone. The motor drives the rotating rod c3156 to rotate, which in turn drives the clamping wheels 3154 to rotate via the belt c3157, thereby driving the foldable screen phone to move forward until the foldable screen phone moves to the center of the flip plate 314. The flip plate 314 stops rotating, and the foldable screen phone is positioned.

[0059] In other words, the drive clamping part 315 can achieve the effect of keeping the foldable screen phone stationary (clamping wheel 3154 does not rotate), and can also achieve the downward transmission of the foldable screen phone (clamping wheel 3154 rotates).

[0060] like Figure 4As shown, the unfolding assembly 32 includes: a fixed frame 321, which is mounted on the frame 1; a linear drive a322, which is mounted on the fixed frame 321; a motion plate 323, which is mounted on the output end of the linear drive a322; an inclined plate 324, which is mounted on both ends of the motion plate 323; a rotating frame 325, which is rotatably disposed between the two sets of inclined plates 324; an L-shaped plate 326, which is slidably disposed on the rotating frame 325, and one end of the L-shaped plate 326 is provided with an inverted buckle 3261; and a driving unit 327, which drives the rotating frame 325 to rotate and the L-shaped plate 326 to move.

[0061] Furthermore, such as Figure 4 As shown, the drive unit 327 includes: a rotary drive component b3271, which is mounted on the inclined plate 324; a fixed rod b3272, which is mounted on one end of the rotating frame 325, and the output end of the rotary drive component b3271 is connected to the fixed rod b3272 via a belt b3273; a rotary drive component c3274, which is mounted on the moving plate 323; a groove 3251 is provided in the rotating frame 325, and the L-shaped plate 326 slides in the groove 3251; an elastic connector a3275, which is disposed between the groove 3251 and the L-shaped plate 326; and a rope 3276, which passes through the elastic connector a3275 and is connected at one end to the L-shaped plate 326, and at the other end to the output shaft of the rotary drive component c3274.

[0062] In this embodiment, the rotary drive a312 drives the working plate 313 to rotate 90°, thereby rotating the foldable screen phone by 90°. The linear drive a322 drives the motion plate 323 to move forward, moving the inclined plate 324, the rotating frame 325, and the L-shaped plate 326 to one side of the clamping assembly 31. The rotary drive b3271 drives the rotating frame 325 and the L-shaped plate 326 to rotate to a horizontal state (the L-shaped plate 326 contacts the top of the foldable screen phone) via the belt b3273. The rotary drive c3274 rotates and pulls the rope 3276, driving the L-shaped plate 326 to slide in the slide groove 3251 (the elastic connector a3275 is compressed by force), causing the buckle 3261 to clamp the upper part of the foldable screen phone. The rotary drive b3271 drives the rotating frame 325 and the L-shaped plate 326 to rotate outward by 180° via the belt b3273, thereby unfolding the foldable screen phone, which facilitates the subsequent touch detection assembly 33 to detect the inner screen.

[0063] Furthermore, such as Figure 11 and Figure 12As shown, the touch detection assembly 33 includes: a truss 331; a slider 332 that slides on the truss 331; a linear drive b333 that is mounted on the bottom of the slider 332; a lifting block 334 that is mounted on the output end of the linear drive b333 and has a sliding groove 3341; a sliding ring 335 that slides within the sliding groove 3341; a rotary drive f336 that is mounted on the sliding ring 335; a rotating ring 337 that is mounted on the output shaft of the rotary drive f336; a swing rod 338 that is mounted on the rotating ring 337; a telescopic part 339 that is mounted on the swing rod 338; and a touch rod 330 that is mounted on the bottom of the telescopic part 339.

[0064] like Figure 11 and Figure 12 As shown, the telescopic part 339 includes: a fixed sleeve 3391, which is mounted on the swing rod 338; a sliding rod b3392, which is slidably disposed within the fixed sleeve 3391, and has a spiral groove 33921 ​​on its outer side; a fixed connecting block 3393, which is mounted within the fixed sleeve 3391 and slides within the spiral groove 33921; a rotary drive d3394, which is mounted within the fixed sleeve 3391; a rotating rod 3395, which is mounted on the output shaft of the rotary drive d3394; and a block 3396, which is mounted on the rotating rod 3395, and the block 3396 and the rotating rod 3395 are inserted into the sliding rod b3392.

[0065] In this embodiment, the slider 332 moves on the truss 331, and the linear drive b333 drives the touch rod 330 to move downward until the touch rod 330 moves above the foldable screen phone. The motor then drives the gear e3352 to rotate, thereby causing the sliding ring 335 to slide within the sliding groove 3341 (along a path such as...). Figure 15 Rotation in the 0-axis direction), the rotary drive f336 drives the rotating ring 337 to rotate (along such as... Figure 15 The rotating drive d3394 rotates along the P-axis, causing the rotating rod 3395 and the block 3396 to rotate, which in turn causes the sliding rod b3392 to rotate. The fixed connecting block 3393 slides in the spiral groove 33921, thereby driving the sliding rod b3392 to move along the M-axis, which in turn causes the touch rod 330 to click on the icon on the outer screen of the foldable phone and drag the icon to move. If the icon moves with the touch rod 330, the outer screen of the foldable phone is qualified; otherwise, it is unqualified. The slider 332 is preferably driven by a cylinder in the truss 331.

[0066] Similarly, when the foldable screen is unfolded, the touch stick 330 is driven to tap the icon on the inner screen of the foldable phone and drag the icon to move it. If the icon moves with the touch stick 330, the inner screen of the foldable phone passes the test; otherwise, it fails.

[0067] It should be noted that: the sliding ring 335 is driven to slide within the sliding groove 3341 (along such that...) Figure 15 Rotating along the 0 axis direction, driving the rotating ring 337 to rotate (along such as...) Figure 15 The P-axis rotation drives the slider b3392 to move along the M-axis, allowing the touch bar 330 to move freely within a certain space, thus enabling the icons on the screen to be dragged at will, facilitating screen detection.

[0068] like Figure 1 and Figure 2 As shown, this embodiment also includes a material dropping mechanism 4, which includes a pipe 41 mounted on the frame 1, with the top of the pipe 41 in a horn-like position.

[0069] When the foldable screen phone passes the inspection, the rotating drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate inward by 180° via the belt b3273, thereby folding the unfolded foldable screen phone up. The inverted buckle 3261 is removed from the foldable screen phone. The rotating drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate outward by 180° via the belt b3273. The rotating drive component a312 drives the working plate 313 to rotate by 90°, thereby driving the foldable screen phone to rotate. The belt c3157 drives the clamping wheel 3154 to rotate, thereby driving the foldable screen phone to move forward onto the conveyor belt 22. The conveyor belt 22 continues to transport the qualified foldable screen phone downward.

[0070] When the foldable phone fails the inspection: the rotating drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate inward by 90° via belt b3273, causing one end of the foldable phone to rotate to a vertical position. The motor then drives the flip plate 314 to rotate 90°, causing the other end of the foldable phone to rotate to a vertical position (its state is as follows). Figure 20 As shown, the belt c3157 drives the clamping wheel 3154 to rotate, so that the foldable screen phone is transferred downward into the pipe 41;

[0071] Furthermore, such as Figure 2 As shown, the transmission mechanism 2 includes: a transmission belt 22, which is mounted on the frame 1 to transmit the foldable screen phone; and a Y-axis rotation adjustment component 23, which rotates along the Y-axis to adjust the position of the foldable screen phone.

[0072] like Figure 3As shown, the Y-axis rotation adjustment assembly 23 includes: a connecting frame a231, which is mounted on the frame 1; an arc-shaped track 232, which is mounted on the connecting frame a231; a rotating disk 233, which is rotatably disposed within the arc-shaped track 232, and a toothed block 2331 is provided on the outer side of the rotating disk 233; a rotating block 234, which is mounted on the rotating disk 233, and a through groove 2341 is provided in the rotating block 234; a rotation drive e235, which is mounted on the connecting frame a231; and a gear d236, which is mounted on the output end of the rotation drive e235 and meshes with the toothed block 2331.

[0073] It should be noted that there are four possible positions for the foldable phone transported on conveyor belt 22 (two with the outer screen facing up and two with it facing down). Therefore, the position of the foldable phone transported on conveyor belt 22 needs to be adjusted. When the foldable phone is transported into the through slot 2341, the rotating block 234 is rotated 180° along the Y-axis by the rotation drive e235, which can adjust the outer screen of the foldable phone to face up. At the same time, when the foldable phone is transported to the flip plate 314, the rotating plate 314 is rotated 0° or 180° by the rotation drive a312 to adjust the position of the foldable phone, which is convenient for subsequent screen inspection.

[0074] Example 2

[0075] like Figure 12 and Figure 15 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0076] like Figure 12 As shown, the display detection mechanism 3 in this embodiment includes an angle detection component 34, which detects the angle between the two sides of the inner screen of the foldable phone; as Figure 13 The foldable phone shown has an angle between the two ends of the inner screen when it is in its natural state. If the angle exceeds 5°, the crease of the inner screen is obvious, and the foldable phone is unqualified.

[0077] The included angle detection assembly 34 includes: a fixed block 341, which is installed at the end of the sliding rod b3392, and a groove 3411 is provided in the fixed block 341; a rotating sleeve 342, which is rotatably disposed in the groove 3411, and a contact rod 330 is installed at one end of the rotating sleeve 342; a detection rod 343, which is installed at the other end of the rotating sleeve 342; a fixed rod d344, which is installed on the rotating sleeve 342; and a rotation drive g345, which is installed on the fixed block 341, and the output end of the rotation drive g345 is connected to the fixed rod d344 via a belt d346.

[0078] In this embodiment, the rotary drive component g345 drives the rotating sleeve 342 to rotate 180° via the belt d346, thereby rotating the contact rod 330 into the groove 3411, and then rotating the detection rod 343 out. The linear drive component b333 drives the detection rod 343 to move downward, so that the detection rod 343 contacts the inner screen. The detection rod 343 is equipped with a position sensor. By rotating along the O-axis and the P-axis, the positions of multiple points are collected on both sides of the inner screen, thereby detecting the screen angle. If the angle is qualified, it is transmitted downward.

[0079] It should be noted that: such as Figure 17 As shown, the inner screen of the foldable phone is divided into G-side and H-side. The moving detection rod 343 contacts the G-side and H-side respectively, and samples several points on the G-side and H-side. Then, the computer fits the G-side and H-side and calculates the angle between the G-side and H-side. If the angle is ≥5°, the foldable phone is unqualified.

[0080] Additionally, during the angle detection, one end of the foldable phone is in a natural state when unfolded, so it is necessary to adjust the buckle 3261 and the clamping wheel 3154 to prevent them from contacting the foldable phone.

[0081] Work steps

[0082] Step 1, Transmission Process: The foldable screen phone is transmitted on conveyor belt 22;

[0083] Step 2, Clamping process: (e.g.) Figure 14 As shown, the foldable phone is transferred to the flip plate 314. The motor drives the rotating rod a3152 to rotate, which in turn drives the connecting rod 3153 to rotate inward. This causes the clamping wheels 3154 to clamp the two sides of the foldable phone. The motor drives the rotating rod c3156 to rotate, which in turn drives the clamping wheels 3154 to rotate via the belt c3157. This causes the foldable phone to move forward until it reaches the center of the flip plate 314. The flip plate 314 then stops rotating, and the foldable phone is positioned.

[0084] Step 3, External Screen Inspection Process: Slider 332 moves on truss 331, linear drive b333 drives touch rod 330 downward until touch rod 330 moves above the foldable screen phone, motor drives gear e3352 to rotate, thereby driving sliding ring 335 to slide in sliding groove 3341 (along such a path) Figure 15 Rotation in the O-axis direction), the rotary drive f336 drives the rotating ring 337 to rotate (along such as... Figure 15 The rotating drive d3394 rotates along the P-axis direction, causing the rotating rod 3395 and the block 3396 to rotate, which in turn causes the sliding rod b3392 to rotate. The fixed connecting block 3393 slides in the spiral groove 33921, thereby driving the sliding rod b3392 to move along the M-axis direction. This causes the touch rod 330 to click on the icon on the outer screen of the foldable phone and drag the icon to move it. If the icon moves with the touch rod 330, the outer screen of the foldable phone is qualified; otherwise, it is unqualified.

[0085] Step 4, Foldable Phone Unfolding Process: Rotary drive component a312 drives the working plate 313 to rotate 90°, causing the foldable phone to rotate 90°. Linear drive component a322 drives the motion plate 323 forward, causing the inclined plate 324, rotating frame 325, and L-shaped plate 326 to move to one side of the clamping assembly 31. Rotary drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate to a horizontal state via belt b3273 (L-shaped plate 326 contacts the top of the foldable phone). Rotary drive component c3274 rotates and pulls the rope 3276, driving the L-shaped plate 326 to slide in the slide groove 3251 (elastic connector a3275 is compressed), causing the buckle 3261 to clamp the upper part of the foldable phone. Rotary drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate outward by 180° via belt b3273, thereby unfolding the foldable phone.

[0086] Step 5, Internal Screen Inspection Process: Drive the touch stick 330 to click on the icon on the internal screen of the foldable phone and drag the icon to move it. If the icon moves with the touch stick 330, the internal screen of the foldable phone passes the inspection; otherwise, it fails.

[0087] Step Six: Screen Angle Detection Process: Rotary drive component a345 drives rotating sleeve 342 to rotate 180° via belt d346, thereby rotating touch rod 330 into groove 3411, and then rotating detection rod 343 out. Linear drive component b333 drives detection rod 343 downward, so that detection rod 343 contacts the inner screen. Detection rod 343 is equipped with a position sensor. By rotating along the 0 axis and P axis, the positions of multiple points on both sides of the inner screen are collected to detect the screen angle. If the angle is qualified, the data is transmitted downward.

[0088] Step 7, Qualified Product Unloading Process: The rotating drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate inward by 180° via the belt b3273, thereby folding up the unfolded foldable screen phone, and the inverted buckle 3261 is removed from the foldable screen phone. The rotating drive component b3271 drives the rotating frame 325 and L-shaped plate 326 to rotate outward by 180° via the belt b3273.

[0089] The rotating drive component a312 drives the working plate 313 to rotate 90°, thereby driving the foldable screen phone to rotate. The belt c3157 drives the clamping wheel 3154 to rotate, thereby driving the foldable screen phone to move forward onto the conveyor belt 22 for downward transmission.

[0090] Step 8, Non-conforming Product Unloading Process: The rotating drive component b3271, via belt b3273, drives the rotating frame 325 and L-shaped plate 326 to rotate inward by 90°, causing one end of the foldable phone to rotate to a vertical position. The motor then drives the flip plate 314 to rotate 90°, causing the other end of the foldable phone to rotate to a vertical position (its state is as follows). Figure 20 As shown, the belt c3157 drives the clamping wheel 3154 to rotate, so that the foldable screen mobile phone is transferred downward into the pipe 41.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
