Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display detection equipment, and specifically to a detection tool for manufacturing waterproof liquid crystal displays. Background Art

[0002] A liquid crystal display is a type of display used in digital clocks and many portable computers. The liquid crystal display uses two pieces of polarized material, and between them is a liquid crystal solution. When an electric current passes through the liquid, the crystals are rearranged so that light cannot pass through them.

[0003] Among them, there is a phenomenon of screen replacement in current mobile phone screens, replacing the original screen with a fog screen, thereby reducing the manufacturing cost of mobile phones. This leads to the need to detect the quality of the screen before screen assembly to prevent a small amount of fog screens from being mixed in. For the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a detection tool for manufacturing waterproof liquid crystal displays, including a bracket. A conveyor belt is fixedly connected to the top of the bracket. A fixed frame is fixedly connected to the outer wall of the bracket. A fixed rod is fixedly connected to the inner wall of the fixed frame. A camera is fixedly connected to the side wall of the fixed rod; A support mechanism is fixedly connected to the inner wall of the fixed frame and is used to drive ultraviolet light to move towards the liquid crystal screen; A limiting mechanism is slidably connected to the side wall of the support mechanism and is used to irradiate ultraviolet rays on the outer wall of the screen; A resistance mechanism is fixedly connected to the bottom of the support mechanism and is used to apply resistance to the operation of the support mechanism, so that the extension speeds of the two support mechanisms are different; Among them, before use, first place the liquid crystal screen on the top of the conveyor belt. Driven by the conveyor belt, it reaches the bottom of the fixed frame. Subsequently, the support mechanism drives the limiting mechanism and the resistance mechanism to irradiate ultraviolet rays on the outer wall of the screen to complete the basic detection process.

[0005] Preferably, the support mechanism includes: A driving component, which is fixedly connected to the inside of the fixed frame through a driving member; The driving member includes a support frame fixedly connected to the inner wall of the fixed frame. An electric telescopic rod is fixedly connected to the side wall of the support frame. The end of the electric telescopic rod away from the support frame is fixedly connected to a fixing plate; A linkage component, which is fixedly connected to the outer wall of the fixing plate through a pressing member; The pressing member includes a rotating frame fixedly connected to the side wall of the fixing plate. A toothed column is rotatably connected to the inner wall of the rotating frame; Among them, when detection is required, the two groups of driving components will be synchronously powered on, forcing the electric telescopic rod to extend, and the electric telescopic rod will drive the limiting mechanism and the resistance mechanism to detect the liquid crystal screen.

[0006] Preferably, the limiting mechanism includes: A reset component, which is slidably connected to the inner wall of the fixed plate through a sliding member; The sliding member includes a sliding frame slidably connected to the inner wall of the chute of the fixed plate. A sliding plate is fixedly connected to the inner wall of the sliding frame. Among them, an ultraviolet lamp is fixedly connected to the inner wall of the sliding frame; A light-shielding component, which is rotatably connected to the inner wall of the sliding plate through a shielding member; The shielding member includes a light-shielding plate rotatably connected to the bottom of the sliding plate. A limiting rod is fixedly connected to the outer wall of the light-shielding plate, and a reflecting mirror is installed on the inner wall of the light-shielding plate; Among them, when the sliding plate is pulled upward, since the outer wall of the light-shielding plate contacts the outer wall of the sliding frame, the resistance received by the light-shielding plate will force the light-shielding plate to rotate around the connection point. At this time, the four light-shielding plates will approach each other and finally form a semi-closed lampshade.

[0007] Preferably, the resistance mechanism includes: A plugging component, which is fixedly connected to the bottom of the support frame through a limiting member; The limiting member includes a hydraulic cylinder fixedly connected to the bottom of the support frame. A piston is slidably connected to the inner wall of the hydraulic cylinder, and a one-way valve is connected through the side wall of the piston; A rotating component, which is rotatably connected to the inner wall of the piston through a pressure-receiving member; The pressure-receiving member includes a rotating tube rotatably connected to the inner wall of the central through hole of the piston. A through hole one is opened on the side wall of the piston, and a through hole two is opened on the side wall of the rotating tube; Among them, both the through hole one and the through hole two are irregular through holes, and the rotating tube can only rotate inside the piston and cannot move horizontally.

[0008] Preferably, the driving component includes a U-shaped sliding rod slidably connected to the side wall of the fixed plate. A rack one is fixedly connected to the side wall of the U-shaped sliding rod, and a spring sliding rod is fixedly connected to the side wall of the fixed plate; Among them, when the two U-shaped sliding rods are mutually extruded, the U-shaped sliding rod will slide along the inner wall of the fixed plate, squeeze the spring sliding rod to deform, and accumulate potential energy.

[0009] Preferably, the linkage component includes a rack two slidably connected to the side wall of the fixed plate. The outer wall of the rack two is meshed with the outer wall of the tooth column, and the outer wall of the tooth column is meshed with the outer wall of the rack one; When the U-shaped slide bar is pressed and slides, the gear bar 1 drives the gear bar 2 to move downward through the gear column, and the gear bar 2 forces the limiting mechanism to move downward along the inner wall of the slide groove of the fixed plate.

[0010] Preferably, the reset assembly includes a spring fixedly connected to the side wall of the fixed plate, and the other end of the spring is fixedly connected to the top of the sliding plate; When the limiting mechanism moves downward, the spring is pulled to drive the sliding plate to move upward along the inner wall of the sliding frame.

[0011] Preferably, the shading assembly includes a torsion spring fixedly connected to the inner wall of the shading plate, and one end of the torsion spring away from the shading plate is fixedly connected to the inner wall of the sliding plate; When the shading plate is compressed and rotated, the torsion spring will be deformed by the rotation pressure and accumulate potential energy. When the sliding plate moves downward again, the shading plate will move downward under the push of the torsion spring. When the outer wall of the shading plate is free from the restriction of the outer wall of the sliding plate, the shading plate will open outward again.

[0012] Preferably, the blocking assembly comprises a sliding rod fixedly connected to the side wall of the piston, and one end of the sliding rod away from the through hole is fixedly connected to the side wall of the fixed plate; Among them, the inner wall of the hydraulic cylinder is filled with liquid, and the mass of the liquid is equal to that of water. When the piston moves laterally, water will flow through the one-way valve, and when the piston moves toward one end of the fixed plate, the one-way valve is in a closed state, and when the piston moves toward the support frame, the one-way valve is in an outwardly extended state.

[0013] Preferably, the rotating assembly includes a fan blade fixedly connected to the inner wall of the rotating tube; When the piston moves toward the support frame, most of the liquid will flow through the central hole of the rotating tube and the inner wall of the one-way valve, and the pressure of the liquid flow will force the rotating tube to rotate.

[0014] The present invention has the following beneficial effects: (1) The present invention utilizes the characteristic of the fog screen itself that it can absorb light, and sets a U-shaped sliding rod inside the device. As the two electric telescopic rods extend, the two U-shaped sliding rods will contact and squeeze each other, forcing the two U-shaped sliding rods to slide along the inner wall of the fixed plate, and the U-shaped sliding rod drives the tooth column to rotate through the tooth bar 1, and the rotating tooth column pushes the sliding frame to slide downward through the tooth bar 2, so that the ultraviolet light source at the bottom of the sliding frame is close to the outer wall of the display screen, thereby enhancing the fog screen's absorption efficiency of ultraviolet rays and improving the device's screen detection efficiency; (2) By utilizing the characteristic of the downward movement of the above-mentioned limiting mechanism, a light-shielding component is arranged inside the device. When the sliding frame moves downward, during the downward movement, the spring will pull the sliding plate, forcing the sliding plate to move upward along the sliding frame. When the sliding plate moves upward under the pulling force, since the outer wall of the light-shielding plate contacts the outer wall of the sliding frame, the resistance received by the light-shielding plate will force the light-shielding plate to rotate around the connection point. At this time, the four light-shielding plates will approach each other and finally form a semi-closed lampshade. When ultraviolet rays irradiate downward inside the sliding frame, the reflecting mirror inside the light-shielding plate can scatter the ultraviolet rays. Through the application of the above components, there is an obvious deviation between the edge of the irradiation position and the rest of the positions, avoiding the unclear edge caused by light scattering and affecting the judgment of the camera.

[0015] (3) By utilizing the characteristic of the electric telescopic rod extending to drive the fixed plate to move, a resistance mechanism is arranged inside the device. After the device completes the detection, at this time, the electric telescopic rod will contract and force the piston to move to the right. At this time, the hydraulic oil on the right side of the piston will be discharged to the left through the central circular tube of the fan blade and the one-way valve. The pressure of the liquid flow will force the rotating tube to rotate, causing the fan blade to drive the through hole two to rotate. After the piston stops moving, the fan blade will also stop operating. Finally, the area of the overlapping hole between the through hole two and the through hole one will determine the resistance received when the piston slides. The larger the overlapping hole area, the smaller the resistance received, and vice versa, the greater the resistance received. By changing the resistance received by the electric telescopic rod when it extends outward, the extension speeds of the two rack bars are different, which makes the staying positions of the sliding frame different after the two rack bars contact each other finally. Through the application of the above components, the contact position between the sliding frame and the display screen is changed, improving the detection accuracy of the device.

Driven by the conveyor belt 14, it reaches the bottom of the fixing frame 15. Subsequently, the support mechanism 1 drives the limiting mechanism 2 and the resistance mechanism 3 to irradiate the outer wall of the screen with ultraviolet rays, completing the basic detection process.

[0021] The support mechanism 1 includes: The driving component 11, and the driving component 11 is fixedly connected inside the fixing frame 15 through a driving member; The driving member includes a support frame 111 fixedly connected to the inner wall of the fixing frame 15.

A toothed column 126 is rotatably connected to the inner wall of the rotating frame 125; Among them, when detection is required, the two driving components 11 will be synchronously powered on, forcing the telescopic electric rod 112 to extend. The telescopic electric rod 112 will drive the limiting mechanism 2 and the resistance mechanism 3 to detect the liquid crystal screen.

[0022] The limiting mechanism 2 includes: The reset component 21, and the reset component 21 is slidably connected to the inner wall of the fixing plate 113 through a sliding member; The sliding member includes a sliding frame 211 slidably connected to the inner wall of the chute of the fixing plate 113. A sliding plate 212 is fixedly connected to the inner wall of the sliding frame 211. Among them, an ultraviolet lamp is fixedly connected to the inner wall of the sliding frame 211; The light-shielding component 22, and the light-shielding component 22 is rotatably connected to the inner wall of the sliding plate 212 through a shielding member; The shielding member includes a light-shielding plate 221 rotatably connected to the bottom of the sliding plate 212. A limiting rod 222 is fixedly connected to the outer wall of the light-shielding plate 221. A reflecting mirror is installed on the inner wall of the light-shielding plate 221; Among them, when the sliding plate 212 is pulled upward, since the outer wall of the light-shielding plate 221 contacts the outer wall of the sliding frame 211, the resistance received by the light-shielding plate 221 will force the light-shielding plate 221 to rotate around the connection point. At this time, the four light-shielding plates 221 will approach each other, and finally form a semi-closed lampshade; Before use, first place the liquid crystal screen on the top of the conveyor belt 14. Driven by the conveyor belt 14, it reaches the bottom of the fixing frame 15. Subsequently, the electric telescopic rod 112 drives the sliding frame 211 to move horizontally synchronously through the fixing plate 113. At this time, the sliding frame 211 will scan the outer wall of the liquid crystal display screen to complete the basic ultraviolet scanning detection process, and during this process, the camera 17 will record the detection results.

[0023] The resistance mechanism 3 includes: The blocking component 31, and the blocking component 31 is fixedly connected to the bottom of the support frame 111 through a limiting member; The limiting member includes a hydraulic cylinder 311 fixedly connected to the bottom of the support frame 111. A piston 312 is slidably connected to the inner wall of the hydraulic cylinder 311, and a one-way valve 313 is connected through the side wall of the piston 312; The rotating component 32, and the rotating component 32 is rotatably connected to the inner wall of the piston 312 through a pressure-receiving member; The pressure-receiving member includes a rotating tube 322 rotatably connected to the inner wall of the central through hole of the piston 312. A through hole one 321 is opened on the side wall of the piston 312, and a through hole two 324 is opened on the side wall of the rotating tube 322; Among them, both the through hole one 321 and the through hole two 324 are irregular through holes, and the rotating tube 322 can only rotate inside the piston 312 and cannot move horizontally; Utilizing the characteristic that the above-mentioned limiting mechanism 2 moves downward, a light-shielding component 22 is provided inside the device. When the sliding frame 211 moves downward, during the downward movement, the spring 213 will pull the sliding plate 212, forcing the sliding plate 212 to move upward along the sliding frame 211. When the sliding plate 212 moves upward under the pulling force, since the outer wall of the light-shielding plate 221 contacts the outer wall of the sliding frame 211, the resistance received by the light-shielding plate 221 will force the light-shielding plate 221 to rotate around the connection point. At this time, the four light-shielding plates 221 will approach each other and finally form a semi-closed lamp shade. When the ultraviolet light irradiates downward inside the sliding frame 211, the reflecting mirror inside the light-shielding plate 221 can scatter the ultraviolet light. Through the application of the above components, there is an obvious deviation between the edge of the irradiation position and the rest of the position, avoiding the influence on the judgment of the camera 17 due to light scattering resulting in unclear edges.

[0024] Example two, please refer to Figures 2 - 9 , The present invention is a detection tool for manufacturing a waterproof liquid crystal display screen. On the basis of Example one, the driving component 11 includes a U-shaped sliding rod 121 slidably connected to the side wall of the fixing plate 113. A rack one 122 is fixedly connected to the side wall of the U-shaped sliding rod 121, and a spring sliding rod 123 is fixedly connected to the side wall of the fixing plate 113; Among them, when the two U-shaped sliding rods 121 are squeezed against each other, the U-shaped sliding rods 121 will slide along the inner wall of the fixed plate 113, squeeze the spring sliding rod 123 to deform, and store potential energy.

[0025] The linkage assembly 12 includes a second rack 124 slidably connected to the side wall of the fixed plate 113. The outer wall of the second rack 124 is meshed with the outer wall of the tooth column 126, and the outer wall of the tooth column 126 is meshed with the outer wall of the first rack 122. Among them, when the U-shaped sliding rod 121 is pressed to slide, the first rack 122 drives the second rack 124 to move downward through the tooth column 126, and the second rack 124 will force the limiting mechanism 2 to move downward along the inner wall of the chute of the fixed plate 113. Taking advantage of the characteristic that the fog screen itself can absorb light, a U-shaped sliding rod 121 is arranged inside the device. Among them, as the two electric telescopic rods 112 extend, at this time the two U-shaped sliding rods 121 will come into contact and squeeze each other, forcing the two U-shaped sliding rods 121 to slide along the inner wall of the fixed plate 113. The U-shaped sliding rod 121 drives the tooth column 126 to rotate through the first rack 122, and the rotating tooth column 126 will push the sliding frame 211 to slide downward through the second rack 124, so that the ultraviolet light source at the bottom of the sliding frame 211 is close to the outer wall of the display screen, enhancing the absorption efficiency of the fog screen for ultraviolet light and improving the screen detection efficiency of the device.

[0026] The reset assembly 21 includes a spring 213 fixedly connected to the side wall of the fixed plate 113, and the other end of the spring 213 is fixedly connected to the top of the sliding plate 212. Among them, when the limiting mechanism 2 moves downward, the spring 213 will be pulled to drive the sliding plate 212 to move upward along the inner wall of the sliding frame 211.

[0027] The light-shielding assembly 22 includes a torsion spring 223 fixedly connected to the inner wall of the light-shielding plate 221, and the end of the torsion spring 223 away from the light-shielding plate 221 is fixedly connected to the inner wall of the sliding plate 212. Among them, when the light-shielding plate 221 is pressed to rotate, the torsion spring 223 will be deformed under the rotational pressure and store potential energy. When the sliding plate 212 moves downward again, the light-shielding plate 221 will move downward under the push of the torsion spring 223. When the outer wall of the light-shielding plate 221 is disengaged from the restriction of the outer wall of the sliding plate 212, the light-shielding plate 221 will open outward again.

[0028] The plugging assembly 31 includes a sliding rod 314 fixedly connected to the side wall of the piston 312, and the end of the sliding rod 314 away from the through hole 321 is fixedly connected to the side wall of the fixed plate 113. Among them, the inner wall of the hydraulic cylinder 311 is filled with liquid, and the mass of this liquid is equal to that of water. When the piston 312 moves horizontally, the water will flow through the one-way valve 313. And when the piston 312 moves towards one end of the fixed plate 113, the one-way valve 313 is in a closed state, while when the piston 312 moves towards the direction of the support frame 111, the one-way valve 313 is in an outwardly expanding state; Utilizing the characteristic that the extension of the electric telescopic rod 112 drives the movement of the fixed plate 113, a resistance mechanism 3 is arranged inside the device. Among them, when the fixed plate 113 moves outward, the fixed plate 113 drives the piston 312 to move outward synchronously through the sliding rod 314, as Figure 8 shown. At this time, the hydraulic oil on the left side of the piston 312 will flow through the gap between the through hole one 321 and the through hole two 324 to the right side of the piston 312, restricting the moving speed of the fixed plate 113 and the sliding rod 314, and slowing down the moving speed of the electric telescopic rod 112 moving outward.

[0029] The rotating assembly 32 includes a fan blade 323 fixedly connected to the inner wall of the rotating tube 322; Among them, when the piston 312 moves towards the direction of the support frame 111, at this time, most of the liquid will flow through the central hole of the rotating tube 322 and the inner wall of the one-way valve 313, and the pressure of the liquid flow at this time will force the rotating tube 322 to rotate; After the device completes the detection, at this time, the electric telescopic rod 112 will contract and force the piston 312 to move to the right. At this time, the hydraulic oil on the right side of the piston 312 will be discharged to the left through the central circular tube of the fan blade 323 and the one-way valve 313. The pressure of the liquid flow will force the rotating tube 322 to rotate, causing the fan blade 323 to drive the through hole two 324 to rotate. And after the piston 312 stops moving, the fan blade 323 will also stop operating. Finally, the area of the overlapping hole between the through hole two 324 and the through hole one 321 will determine the resistance received when the piston 312 slides. The larger the overlapping hole area, the smaller the resistance received, and vice versa, the greater the resistance received. By changing the resistance received when the electric telescopic rod 112 extends outward, the outward extension speeds of the two rack bars one 122 are different, which makes the stopping positions of the sliding frame 211 different after the two rack bars one 122 come into contact with each other finally. Through the application of the above components, the contact position between the sliding frame 211 and the display screen is changed, improving the detection accuracy of the device.

[0030] A specific application of this embodiment is: Before use, first place the liquid crystal screen on the top of the conveyor belt 14. Driven by the conveyor belt 14, it reaches the bottom of the fixed frame 15. Subsequently, the electric telescopic rod 112 drives the sliding frame 211 to move horizontally synchronously through the fixed plate 113. At this time, the sliding frame 211 will scan the outer wall of the liquid crystal display screen, completing the basic ultraviolet scanning detection process, and the camera 17 will record the detection results during this process; Taking advantage of the characteristic that the fog screen can absorb light itself, a U-shaped slide bar 121 is arranged inside the device. Among them, as the two electric telescopic rods 112 extend, at this time, the two U-shaped slide bars 121 will contact and squeeze each other, forcing the two U-shaped slide bars 121 to slide along the inner wall of the fixed plate 113. The U-shaped slide bar 121 drives the tooth column 126 to rotate through the first tooth bar 122, and the rotating tooth column 126 will push the sliding frame 211 to slide downward through the second tooth bar 124, so that the ultraviolet light source at the bottom of the sliding frame 211 is close to the outer wall of the display screen, enhancing the absorption efficiency of the fog screen for ultraviolet light and improving the screen detection efficiency of the device; Taking advantage of the characteristic that the above-mentioned limiting mechanism 2 moves downward, a light-shielding component 22 is arranged inside the device. When the sliding frame 211 moves downward, during the downward movement, the spring 213 will pull the sliding plate 212, forcing the sliding plate 212 to move upward along the sliding frame 211. When the sliding plate 212 moves upward under the pulling force, since the outer wall of the light-shielding plate 221 contacts the outer wall of the sliding frame 211, the resistance received by the light-shielding plate 221 will force the light-shielding plate 221 to rotate around the connection point. At this time, the four light-shielding plates 221 will approach each other and finally form a semi-closed lamp shade. When the ultraviolet light irradiates downward inside the sliding frame 211, the reflecting mirror inside the light-shielding plate 221 can scatter the ultraviolet light. Through the application of the above components, there is an obvious deviation between the edge of the irradiation position and the other positions, avoiding unclear edges caused by light scattering and affecting the judgment of the camera 17.

[0031] Taking advantage of the characteristic that the above-mentioned electric telescopic rod 112 extends to drive the fixed plate 113 to move, a resistance mechanism 3 is arranged inside the device. Among them, when the fixed plate 113 moves outward, the fixed plate 113 drives the piston 312 to move outward synchronously through the sliding rod 314, as Figure 8 shown. At this time, the hydraulic oil on the left side of the piston 312 will flow from the gap between the through hole one 321 and the through hole two 324 to the right side of the piston 312, restricting the outward movement speed of the fixed plate 113 and the sliding rod 314 and slowing down the outward movement speed of the electric telescopic rod 112; After the device completes the detection, the electric telescopic rod 112 will contract at this time, forcing the piston 312 to move to the right. At this time, the hydraulic oil on the right side of the piston 312 will be discharged to the left through the central circular tube of the fan blade 323 and the one-way valve 313. The pressure of the liquid flow will force the rotating tube 322 to rotate, causing the fan blade 323 to drive the through hole two 324 to rotate. After the piston 312 stops moving, the fan blade 323 will also stop operating. Finally, the area of the overlapping hole between the through hole two 324 and the through hole one 321 will determine the resistance received when the piston 312 slides. The larger the overlapping hole area, the smaller the resistance received, and vice versa, the greater the resistance received. By changing the resistance received when the electric telescopic rod 112 extends outward, the extension speeds of the two first racks 122 are different, which causes the stop positions of the sliding frame 211 to be different after the two first racks 122 come into contact with each other finally. Through the application of the above components, the contact position between the sliding frame 211 and the display screen is changed, improving the detection accuracy of the device.
