Description

Technical Field

[0001] The present application relates to the technical field of LCD display screen processing, and in particular to a panel transfer mechanism for LCD display screen processing. Background Art

[0002] LCD display is a display technology that uses liquid crystal as the main display material. It changes the arrangement direction of liquid crystal molecules under the action of electric field, thereby changing the polarization state of the light passing through, and forms a visible image through the filtering of polarizers. Before the LCD display is transferred to the next process for pasting and gluing, the transferred LCD display processing panel needs to be cleaned before pasting and gluing can be carried out. The manual cleaning method is not only wasteful of manpower, but also requires cleaning after transfer, which reduces the production efficiency of LCD display processing panels.

[0003] In the related technology, a Chinese patent with application number CN202410049566.7 proposes a panel transfer mechanism for LCD display processing, including a base, a transfer assembly and a cleaning assembly. The cleaning assembly includes a placement plate, a support plate, a push column and a cleaning plate. The transfer assembly is detachably connected to the base and is located above the base. The placement plate is detachably connected to the base and is located above the base. The support plate is detachably connected to the placement plate and is located above the placement plate. The push column is detachably connected to the support plate and is located on one side of the support plate. The cleaning plate is detachably connected to the push column and is located on the side of the push column away from the support plate. By adding a cleaning assembly, the overall automatic cleaning function is given, thereby greatly improving the production efficiency of the LCD display processing panel.

[0004] The above-mentioned related technologies have the following defects: generally, the processing workshops of LCD panels are clean rooms, and there are strict control requirements on the content of suspended particles in the air in the workshop. However, during the production process in the workshop, due to factors such as personnel entering and exiting, materials being brought in or equipment emissions, there are still trace amounts of dust particles in the workshop. Therefore, the LCD panel must be detected and cleaned for trace dust before transfer and gluing. The cleaning board in the above-mentioned related technology may involve direct contact with the panel during the cleaning process, and has extremely high requirements on the cleanliness of the cleaning board itself. Otherwise, the amount of dust on the panel will be increased, affecting the stability of quality control. Summary of the invention

[0045] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0046] The present application embodiment discloses a panel transfer mechanism for LCD display processing. Figure 1 and Figure 2 , which includes a base 1 and a transfer assembly 11. The transfer assembly 11 can be a manipulator, which has a suction cup for adsorbing the panel 8, and can transfer the panel 8 from one station to another station. The specific conventional technical means are not repeated here. The base 1 is provided with a cleaning rack 2 located on one side of the track of the panel 8 transferred by the transfer assembly 11. A cleaning station 21 is provided on the side of the cleaning rack 2 close to the transfer assembly 11. The middle of the cleaning rack 2 has a hollow part for the panel 8 to pass through.

[0047] The cleaning rack 2 is provided with:

[0048] The lighting component 22 is used to perform side lighting on the panel 8 on the cleaning station 21, which is specifically a strip light source installed on the inner side wall of the hollow part of the cleaning frame 2, and its lighting direction extends along the plane to be cleaned of the panel 8;

[0049] The positioning image recognition component 23 is used to capture the image of the panel 8 on the cleaning station 21 and locate the dust position; the positioning image recognition component 23 may specifically include a CCD industrial camera and a matching image recognition processing system, and the image recognition processing system is used to analyze and process the image taken by the CCD industrial camera to locate the plane coordinate position of the dusty part compared to the cleaning rack 2. And

[0050] The cleaning robot 24 is arranged on the side of the cleaning frame 2 away from the transfer component 11, and a cleaning seat 3 is arranged at its output end. The cleaning robot 24 can specifically be a two-axis robot; the cleaning robot 24 is controlled and connected with the image recognition processing system, and can move the cleaning seat 3 to the corresponding position according to the dust position determined by the positioning image recognition component 23; the above control process can be simply combined based on conventional means, which belongs to conventional technology and will not be repeated here.

[0051] A cleaning mechanism is provided on the cleaning seat 3, see Figure 1 and Figure 2 , cleaning agencies include:

[0052] The dust hood 41 has an air inlet end corresponding to the panel 8 on the cleaning station 21 and an air outlet end connected to a negative pressure suction device. Specifically, an air pipe is connected between the dust hood 41 and the negative pressure suction device, and a solenoid valve is provided on the air pipe;

[0053] A dust removal component, used to remove dust on the panel 8 that cannot be cleaned by negative pressure suction;

[0054] The inspection camera 42 is used to capture images of the area corresponding to the air inlet end of the dust hood 41. The inspection camera 42 is also connected to an image recognition processing system. The image recognition processing system can analyze and recognize the images captured by the inspection camera 42 to determine whether there is dust in the target area; and

[0055] The inspection controller is configured to control the dust removal component to operate when dust still exists in the image captured by the inspection camera 42 after the vacuum hood 41 performs negative pressure suction.

[0056] In this way, when the transfer component 11 is transferring the panel 8 of the LCD display screen, the panel 8 is first transferred to the cleaning station 21 of the cleaning rack 2, and the lighting component 22 on the cleaning rack 2 lights the surface of the panel 8 from the side, and the positioning image recognition component 23 captures the image of the surface of the panel 8 and identifies and locates the position of the dust, and then the cleaning robot 24 moves the cleaning seat 3 thereon to the corresponding position in sequence; the dust hood 41 performs non-contact suction on the dust on the panel 8 under the action of the negative pressure suction device, and according to the different degrees of dust adhesion, the dust attached to the panel 8 can be sucked out with a certain probability.

[0057] After the dust hood 41 completes the suction, the inspection camera 42 captures the dust at that position. If the dust at that position has been removed, the cleaning robot 24 controls the cleaning seat 3 to move to the next dust position. If the dust at that position has not been removed, the inspection controller controls the dust removal component to work, and the dust removal component transfers the dust that has not been cleaned at that position of the panel 8, so as to completely remove the dust on the panel 8. Repeating the above steps can completely clean the dust on the panel 8, so that the panel 8 meets the cleanliness standard during the transfer process.

[0058] Among them, the dust on the panel 8 can be comprehensively located by positioning the image recognition component 23, and then the cleaning seat 3 can be gradually moved to the position where the dust exists by the cleaning robot 24, and each dust can be cleaned at a single point with the help of the dust hood 41, which can improve the cleaning efficiency of the panel 8; and if the non-contact dust hood 41 cannot clean the dust attached to the panel 8, the dust will be cleaned by the dust removal component to ensure the cleaning effect and reduce the possibility of secondary pollution during the cleaning of the dust on the panel 8.

[0059] Specifically, the purpose is to reduce as much as possible the probability of secondary contamination of the panel 8 by the dust removal component when removing dust from the panel 8, and to ensure the cleaning effect of the dust on the panel 8 that is difficult to remove.

[0060] Reference Figure 2 and Figure 3 The aforementioned dust removal assembly includes:

[0061] The unwinding roller 51 has a strip-shaped electrostatic dust removal sticker 52 wound thereon, wherein one side of the electrostatic dust removal sticker 52 is a dust removal side and the other side is a smooth side;

[0062] A winding roller 53, used for winding up the electrostatic dust removal sticker 52 after dust removal;

[0063] The guide rollers 54 are rotatably mounted in the dust collecting cover 41 and are provided with two of them. The guide rollers 54 are located on the side of the non-dust collecting surface of the electrostatic dust removing sticker 52 and are used to guide the electrostatic dust removing sticker 52 to partially move to the air inlet end close to the dust collecting cover 41. After the electrostatic dust removing sticker 52 is unwound from the unwinding roller 51, it passes by the two guide rollers 54 and is rewound on the rewinding roller 53.

[0064] A pusher head 61 is located between the two guide rollers 54 and on the non-dust removal side of the electrostatic dust removal patch 52; and

[0065] The linear drive member 62 is used to drive the pusher head 61 to approach or move away from the electrostatic dust removal sticker 52. It is connected to the inspection controller. The linear drive member 62 can specifically be a micro cylinder, a micro electric push rod, a micro linear motor, etc. The inspection controller is configured to control the linear drive member 62 to drive the pusher head 61 to extend and then retract when there is still dust in the image captured by the inspection camera 42 after the vacuum hood 41 is sucked under negative pressure.

[0066] Specifically, refer to Figure 2 and Figure 3 A push plate 63 is fixedly connected to the output end of the linear driving member 62, and an elastic member 64 is fixedly connected between the push plate 63 and the push head 61. The elastic member 64 is configured as a spring and one end thereof is fixedly connected to the push plate 63 and the other end is fixedly connected to the push head 61. A guide rod 65 that passes through the push plate 63 is fixedly connected to the push head 61.

[0067] And to facilitate the replacement of the electrostatic dust removal sticker 52, refer to Figure 2 and Figure 3The unwinding roller 51 and the rewinding roller 53 are both arranged outside the dust cover 41. The dust cover 41 is provided with a through hole 44 for the electrostatic dust removal sticker 52 to pass through at the position corresponding to the unwinding roller 51 and the rewinding roller 53. The dust cover 41 is provided with a stepping motor 55 for driving the rewinding roller 53 to rotate stepwise by a set angle. The stepping motor 55 is connected to a dust removal controller, which is connected to a linear drive member 62. The dust removal controller is configured to control the stepping motor 55 to work when the linear drive member 62 drives the pusher head 61 to extend and retract.

[0068] In this way, when there is dust on the panel 8 that cannot be removed by the negative pressure suction of the dust hood 41, the inspection controller controls the linear drive 62 to work, and the linear drive 62 drives the push plate 63 to extend toward the direction close to the air inlet end of the dust hood 41, so that the push head 61 moves synchronously, so that the push head 61 pushes the electrostatic dust removal sticker 52 to extend out of the dust hood 41 and contact with the dust on the panel 8. The adsorption force of the dust removal surface of the electrostatic dust removal sticker 52 on the dust is greater than the adhesion force of the dust on the panel 8. Therefore, when the linear drive 62 drives the push plate 63 to drive the push head 61 to retract, the stepper motor 55 is controlled to drive the winding roller 53 to wind up the extended electrostatic dust removal sticker 52, so that the electrostatic dust removal sticker 52 removes the dust from the panel 8, thereby achieving the cleaning effect of the dust removal component on the stubborn dust on the panel 8.

[0069] During this process, the setting of the elastic member 64 between the push plate 63 and the push head 61 can realize the elastic abutment between the push head 61 and the electrostatic dust removal sticker 52 and the panel 8, so as to avoid damage to the panel 8 and ensure the adhesion effect of the electrostatic dust removal sticker 52 on dust; the setting of the stepper motor 55 facilitates the control of the electrostatic dust removal sticker 52 to adsorb a certain area and then rewind the area, so that the push head 61 can always correspond to a new electrostatic dust removal sticker 52 after recycling, so as to ensure the dust removal effect.

[0070] Furthermore, in order to prevent the winding roller 53 from pulling the unwinding rear roller to unwind when stepping and rotating to rewind the electrostatic dust removal sticker 52, thereby affecting the rewinding effect of the used winding roller 53, further explanation is required.

[0071] First, the stepper motor 55 has a self-braking function, that is, when the push head 61 pushes the electrostatic dust removal sticker 52 to extend out of the dust hood 41, the electrostatic dust removal sticker 52 cannot pull the winding roller 53 to rotate in the opposite direction, and can only pull the unwinding roller 51 to unwind part of the electrostatic dust removal sticker 52 so that the length of the electrostatic dust removal sticker 52 satisfies the need for the push head 61 to extend out of the dust hood 41.

[0072] Secondly, when the reeling roller 53 reels the electrostatic dust removal sticker 52 after the push head 61 is retracted, the unwinding roller 51 shall not continue to unwind or avoid excessive unwinding of the electrostatic dust removal sticker 52. Therefore, a damping component (not shown in the figure) for increasing the unwinding rotation resistance of the unwinding roller 51 is provided between the unwinding roller 51 and the dust hood 41. The damping component can be a damping rubber ring provided between the unwinding roller 51 and the dust hood 41, which can trigger the unwinding roller 51 to rotate and unwind only when it is subjected to sufficient driving force. For example, when the linear driving member 62 pushes the push head 61 to extend, its driving force directly acts on the unwinding roller 51 with the help of the electrostatic dust removal sticker 52, which can drive the unwinding roller 51 to rotate and unwind. When the reeling roller 53 is rewinding the electrostatic dust removal sticker 52 attached to the panel 8, the inertia force of the electrostatic dust removal sticker 52 following the reeling roller 53 is not enough to pull the unwinding roller 51 to rotate.

[0073] Alternatively, the damping component can be an electromagnet and a ferromagnetic body disposed between the unwinding roller 51 and the dust cover 41. Only when the stepper motor 55 is working, the electromagnet is energized to lock the unwinding roller 51, and when the linear drive member 62 is working, the electromagnet is de-energized, and the unwinding roller 51 can rotate freely. In this way, the electrostatic dust removal sticker 52 can be precisely controlled, ensuring the dust removal effect while avoiding waste or interference with other processes.

[0074] In addition, in order to prevent the dust hood 41 from affecting the dust removal performance of the dust removal surface of the electrostatic dust removal patch 52 when sucking dust by negative pressure, refer to Figure 2 and Figure 3 A dust hood 7 is fixedly connected in the dust hood 41, and a notch 71 for the push head 61 to extend is provided at the movable end of the dust hood 7 close to the air inlet end of the dust hood 41. The guide roller 54 and the push head 61 are both arranged in the dust hood 7, and a streamline surface 72 is provided on the outside of the dust hood 7 corresponding to the guide roller 54 to prevent the dust hood 41 from generating turbulence and causing noise during negative pressure suction; a ventilation gap 43 is reserved between the dust hood 7 and the dust hood 41, and the ventilation gap 43 is used for stable connection between the dust hood 41 and the upper air pipe thereof to ensure the negative pressure suction effect; at the same time, a flat tube 73 is provided between the dust hood 7 and the dust hood 41 to connect the through hole 44 on the dust hood 41 and the inner cavity of the dust hood 7, and the width of the flat tube 73 is less than the thickness of the dust hood 41 to reserve the above-mentioned ventilation gap 43.

[0075] In this way, the dust removal component is encapsulated in an independent dust removal hood 7. On the basis of not affecting the normal suction effect of the dust hood 41, the electrostatic dust removal patch 52 can be relatively well protected to ensure that the electrostatic dust removal patch 52 is always in good condition; moreover, the two ends of the electrostatic dust removal patch 52 extend out of the dust hood 41 with the help of the flat tube 73, which can also avoid the problem of reduced negative pressure suction performance of the dust hood 41 caused by the electrostatic dust removal patch 52 directly passing through the dust hood 41.

[0076] In addition, as a setting for applicability, refer to Figure 1 and Figure 2 Limiting skirts 56 are fixedly connected to both ends of the unwinding roller 51, the winding roller 53 and the guide roller 54. The gap between the two opposite limiting skirts 56 is adapted to the width of the electrostatic dust removal sticker 52 to improve the accuracy of the electrostatic dust removal sticker 52 when moving and prevent it from deviation.

[0077] The implementation principle of a panel transfer mechanism for processing an LCD display screen in the embodiment of the present application is as follows:

[0078] When the transfer component 11 is transferring the panel 8 of the LCD display screen, the panel 8 is first transferred to the cleaning station 21, the lighting component 22 lights the surface of the panel 8 from the side, the positioning image recognition component 23 captures the image of the surface of the panel 8 and identifies and locates the position of the dust, and then the cleaning robot 24 moves the cleaning seat 3 thereon to the corresponding position in sequence; the dust hood 41 performs non-contact suction on the dust on the panel 8 under the action of the negative pressure suction device, and according to the different degrees of dust adhesion, the dust attached to the panel 8 can be sucked out with a certain probability.

[0079] After the dust hood 41 completes the suction, the inspection camera 42 captures the dust at that position. If the dust at that position has been removed, the cleaning robot 24 controls the cleaning seat 3 to move to the next dust position. If the dust at that position has not been removed, the inspection controller controls the linear drive 62 to work, and the pusher head 61 pushes the electrostatic dust removal sticker 52 to extend and adhere to the panel 8 to transfer the dust that has not been cleaned at that part of the panel 8, and then the stepper motor 55 controls the winding roller 53 to wind up the electrostatic dust removal sticker 52 to achieve the purpose of completely removing the dust on the panel 8. Repeating the above steps can completely clean the dust on the panel 8, so that the panel 8 meets the cleanliness standard during the transfer process.

[0080] Among them, the dust on the panel 8 can be comprehensively located by positioning the image recognition component 23, and then the cleaning seat 3 can be gradually moved to the position where the dust exists by the cleaning robot 24, and each dust can be cleaned at a single point with the help of the dust hood 41, so as to improve the cleaning efficiency of the panel 8; and if the non-contact dust hood 41 cannot clean the dust attached to the panel 8, the dust will be cleaned by the electrostatic dust removal sticker 52 to ensure the cleaning effect and reduce the possibility of secondary pollution during the cleaning of the dust on the panel 8.
