Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid crystal display panel production. The present application specifically relates to a gasket cleaning device and system of a diaphragm conveying unit. BACKGROUND

[0002] In the existing production process of a liquid crystal display panel, a conveying unit (box) carrying a liquid crystal glass panel is usually used to convey the liquid crystal panel. In order to reduce the collision force between the liquid crystal glass panel and the conveying unit, a gasket with a damping effect is usually arranged in the conveying unit. The gasket supports the panel surface of the liquid crystal glass panel uniformly through surface damping force, thereby playing a protection role.

[0003] However, in long-term use, the gasket is easy to be contaminated with dust and impurities of the liquid crystal glass panel due to the material and adsorption property of the gasket. Therefore, the surface of the gasket needs to be cleaned regularly. In the cleaning process, manual wiping is usually used. However, it is difficult for manual work to make the surface of the gasket bear force uniformly due to the thin thickness of the gasket and the certain damping property of the surface of the gasket. This easily causes regional dirt residue and is not easy to be identified by naked eyes due to the color of the gasket material. Long-term uneven force on the gasket easily causes local deformation, which cannot guarantee flatness. In turn, the replacement frequency of the gasket is high, the use cost is increased, and the gasket is easy to scratch the liquid crystal glass panel if not replaced in time. SUMMARY

[0004] The present application aims to provide a gasket cleaning device and system of a diaphragm conveying unit, which solves the problem of easy deformation and low cleaning quality due to uneven force in the cleaning of the gasket of a liquid crystal glass panel.

[0041] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described with reference to the accompanying drawings, in which the same reference numerals represent the same or similar components having the same function.

[0042] In this context, "schematic" means "serving as an example, illustration or explanation", and any diagram, embodiment described as "schematic" in this context should not be interpreted as a more preferred or more advantageous technical solution. In order to make the drawings simple, only the parts related to the present exemplary embodiments are shown in the drawings, which do not represent the actual structure and true scale of the product.

[0043] Figure 1 Fig. 1 shows a schematic diagram of the use of a gasket cleaning device of a membrane conveying unit according to an embodiment of the present application. Figure 1 According to a first aspect of the present application, a gasket cleaning device of a membrane conveying unit is provided, which can be placed on a work surface 100, and the gasket cleaning device of the membrane conveying unit comprises a conveying frame 10 and a dust-sticking roller assembly 20. The conveying frame 10 comprises a conveying unit 11 and a support frame 12. The support frame 12 has a support end away from the work surface. The conveying unit 11 is arranged at the support end of the support frame 12 and has a conveying surface 13 parallel to the work surface. The distance between the work surface and the support end is a set height. The conveying unit 11 has the conveying surface 13. The conveying surface 13 can roll along a conveying direction A.

[0044] Figure 2 Fig. 2 shows a schematic diagram of a gasket cleaning device of a membrane conveying unit according to an embodiment of the present application. Figure 2The dust-sticking roller assembly 20 is arranged on the conveying direction A. The dust-sticking roller assembly 20 comprises a first pair of upper dust-sticking rollers 211, a first pair of lower dust-sticking rollers 212, a second pair of upper dust-sticking rollers 221 and a second pair of lower dust-sticking rollers 222. The dust-sticking rollers in the first pair of upper dust-sticking rollers 211, the first pair of lower dust-sticking rollers 212, the second pair of upper dust-sticking rollers 221 and the second pair of lower dust-sticking rollers 222 are arranged in a direction perpendicular to the working surface. The dust-sticking rollers in the first pair of upper dust-sticking rollers 211, the first pair of lower dust-sticking rollers 212, the second pair of upper dust-sticking rollers 221 and the second pair of lower dust-sticking rollers 222 rotate clockwise or counterclockwise (clockwise or counterclockwise rotation).

[0045] A dust-sticking gap is formed between the dust-sticking rollers in the first pair of dust-sticking rollers and the second pair of dust-sticking rollers; the dust-sticking gap is smaller than the thickness of the gasket, and a linear dust-sticking area B parallel to the axial direction of the dust-sticking rollers is formed between the dust-sticking rollers in the first pair of dust-sticking rollers and the second pair of dust-sticking rollers. The linear dust-sticking areas of the first pair of upper dust-sticking rollers 211, the first pair of lower dust-sticking rollers 212, the second pair of upper dust-sticking rollers 221 and the second pair of lower dust-sticking rollers 222 are located on the same dust-sticking plane C, and the dust-sticking plane C is in the same horizontal plane as the conveying surface 13. In order to ensure the cleaning effect of the gasket and not to cause excessive surface extrusion of the gasket, the thickness of the dust-sticking gap is generally 75%-80% of the thickness of the gasket.

[0046] Therefore, when the gasket 90 to be cleaned enters the linear dust-sticking area B between the first pair of dust-sticking rollers and the second pair of dust-sticking rollers along the conveying direction A, the upper and lower roller bodies achieve bidirectional dust-sticking cleaning of the surface of the gasket through micro-pressure contact, effectively removing the adhered particles; at the same time, since the dust-sticking gap is accurately controlled to be 75%-80% of the thickness of the gasket, the cleaning effect is ensured, and the gasket is prevented from being excessively pressed and deformed or damaged. The linear dust-sticking area B is uniformly distributed along the axial direction of the dust-sticking rollers, ensuring that the gasket is uniformly stressed when passing through, and the cleaning process is stable and reliable, avoiding warping or displacement caused by uneven stress.

[0047] Therefore, the gasket cleaning device of the diaphragm conveying unit has the advantages of being able to efficiently remove the dust and impurities adhered to the surface of the gasket, while avoiding damage to the gasket. Through the synergistic effect of the two pairs of dust-sticking rollers, a stable pressure field is formed in the linear dust-sticking area, ensuring that the cleaning force is uniform and consistent. The conveying surface and the dust-sticking plane are designed to be coplanar, which makes the gasket pass smoothly, reduces the running resistance and the risk of deviation. The entire cleaning process does not need to be stopped for operation, and can be continuously operated, significantly improving the production efficiency. The structure is compact, easy to maintain, and suitable for electronic material processing environments with high cleanliness requirements.

[0048] Figure 3 A use process diagram of the gasket cleaning device of the diaphragm conveying unit in an embodiment of the present application is shown, referring to Figure 3The rubber layer outside the upper rollers 211, 221 and the lower rollers 212, 222 of the first and second bonding roller pairs has a thickness of 0.5-0.8 mm, so that when the gasket 90 needs to be cleaned, the gasket 90 is placed on the conveying surface 13 of the gasket conveying unit and is conveyed from the D1 position to the D2 position, and the upper and lower surfaces of the gasket 90 are pressed and adhered to the rubber layer outside the upper rollers 211, 221 and the lower rollers 212, 222 of the first and second bonding roller pairs, so as to clean the upper and lower surfaces of the gasket 90.

[0049] Referring to Figure 3 In order to clean the dirt outside the upper rollers 211, 221 and the lower rollers 212, 222 of the first and second bonding roller pairs in time, the upper roller of the bonding roller of the first and second bonding roller pairs is far away from the working surface in the linear bonding area, and the lower roller of the bonding roller of the first and second bonding roller pairs is close to the working surface in the linear bonding area.

[0050] Referring to Figure 3 In an embodiment of the gasket cleaning device of the unit, the device further comprises an end bonding roller pair. The end bonding roller pair comprises an upper end bonding roller 31 and a lower end bonding roller 32. The bonding force of the upper end bonding roller 31 and the lower end bonding roller 32 is greater than that of the upper rollers 211, 221 and the lower rollers 212, 222 of the first and second bonding roller pairs. The axial direction of the upper end bonding roller and the lower end bonding roller is parallel to the axial direction of the bonding rollers in the first and second bonding roller pairs.

[0051] The thickness of the rubber layer of the upper end bonding roller 31 and the lower end bonding roller 32 is 1.5-2.5 mm. The end bonding roller pair can effectively remove the dust and residues attached to the outer rubber layer of the first and second bonding roller pairs, so as to ensure that the main rollers are kept clean. When the gasket to be cleaned is conveyed to the D3 position, the edge area of the gasket to be cleaned is also cleaned by the strong bonding effect between the upper end bonding roller 31 and the lower end bonding roller 32, so as to further improve the overall cleaning effect. The structure is reasonable and can realize online continuous operation, effectively prolong the service life of the rollers, and ensure the stability of the film processing quality.

[0052] Referring to Figure 3The upper end adhesive roller 31 is located in a direction in which the upper rollers of the first adhesive roller pair upper roller 211, the first adhesive roller pair lower roller 212, and the second adhesive roller pair upper roller 221, the second adhesive roller pair lower roller 222 are away from the work surface, and forms an outer circumferential face transmission with the outside of the upper rollers of the first adhesive roller pair upper roller 211, the first adhesive roller pair lower roller 212, and the second adhesive roller pair upper roller 221, the second adhesive roller pair lower roller 222, so that dust on the upper rollers of the first adhesive roller pair upper roller 211, the first adhesive roller pair lower roller 212, and the second adhesive roller pair upper roller 221, the second adhesive roller pair lower roller 222 can be adhered to the outer circumferential face of the upper end adhesive roller 31.

[0053] Referring to Figure 3 The lower end adhesive roller 32 is located in a direction in which the lower rollers of the first adhesive roller pair upper roller 211, the first adhesive roller pair lower roller 212, and the second adhesive roller pair upper roller 221, the second adhesive roller pair lower roller 222 are close to the work surface, and forms an outer circumferential face transmission with the outside of the lower rollers of the first adhesive roller pair upper roller 211, the first adhesive roller pair lower roller 212, and the second adhesive roller pair upper roller 221, the second adhesive roller pair lower roller 222, so that dust on the lower rollers of the first adhesive roller pair upper roller 211, the first adhesive roller pair lower roller 212, and the second adhesive roller pair upper roller 221, the second adhesive roller pair lower roller 222 can be adhered to the outer circumferential face of the lower end adhesive roller 32.

The first adhesive roller pair and the second adhesive roller pair of the dust adhering roller assembly and the end adhesive roller pair are assembled to the frame 80 by bearing members.

[0055] Referring to Figure 1 , 4, the adjustment support shaft 40 is parallel to the axial arrangement of the first bonding roller pair upper roller 211, the first bonding roller pair lower roller 212, and the second bonding roller pair upper roller 221, the second bonding roller pair lower roller 222. The two ends of the adjustment support shaft are respectively supported by a micro-motion assembly that can move perpendicular to the working surface. The micro-motion assembly is a micro-motion motor, and the output shaft of the micro-motion motor is arranged in a direction perpendicular to the working surface. The ends of the output shaft support the two ends of the adjustment support shaft. The micro-motion motor can be a servo motor or a stepper motor. Thus, the height position of the adjustment support shaft can be accurately controlled by the micro-motion motor, the distance between the dust transfer roller assembly and the working surface can be finely adjusted, the tension between the cleaning pad 90 and the first bonding roller pair and the second bonding roller pair can be formed, and the dust transfer efficiency can be improved. Improve the versatility and operation accuracy of the equipment.

[0056] Referring to Figure 1 , 4 , the micro-motion motors supported at the two ends of the adjustment support shaft are respectively a first support motor and a second support motor. The first support motor and the second support motor are respectively driven by first motor control information and second motor control information. When the first support motor receives the first motor control information, the output shaft of the first support motor extends, driving the first end of the adjustment support shaft 40 to rise in a direction away from the working surface from the initial position to the first adjustment position F1 along a direction perpendicular to the working surface.

[0057] Referring to Figure 4 , when the second support motor receives the second motor control information, the output shaft of the second support motor extends, driving the second end of the adjustment support shaft 40 to rise in a direction away from the working surface from the initial position to the second adjustment position F2 along a direction perpendicular to the working surface. When the cleaning pad 90 appears local relaxation in multiple uses, the position of the adjustment support shaft 40 can be adjusted from the first adjustment position F1 to the second adjustment position F2, thereby increasing the surface tension of the cleaning pad 90 during cleaning, and ensuring the cleaning effect.

[0058] Referring to Figure 4 , the initial position of the two ends of the adjustment support shaft 40 is that the upper shaft surface of the adjustment support shaft 40 is horizontal with the same bonding plane C formed by the linear bonding area B of the first bonding roller pair upper roller 211, the first bonding roller pair lower roller 212, and the second bonding roller pair upper roller 221, the second bonding roller pair lower roller 222.

[0064] Fig. 9 shows a schematic view of the structure of the gasket cleaning device of the diaphragm conveying unit in another embodiment of the present application, referring to Fig. 1, the gasket cleaning device of the diaphragm conveying unit is capable of corresponding to the conveying position G1 of the conveying belt of the diaphragm conveying unit. The diaphragm conveying unit, which is placed with the gasket to be cleaned, is capable of moving to the conveying position G1 under the transmission of the conveying belt. Figure 5 ​​​​​The sorting head 53 has an identification surface capable of facing the conveying surface 13. The sorting identification module is arranged on the identification surface and is capable of identifying the image of the gasket staying in the initial position according to the identification instruction, obtaining the gasket defect image according to the gasket image of the initial position and the edge identification algorithm. According to the defect image, the usable gasket information and the recycled gasket information are obtained. The input end of the sorting identification module is connected to the input end of the sorting controller.

[0065] If the defect image on the gasket, the dust coverage and the wrinkle coverage are greater than the set coverage value or the dust value, the recycled gasket information or instruction is generated, so that the sorting head 53 moves to the recycling position after picking up the gasket in the initial position. If not, the usable gasket information is generated, so that the sorting head 53 moves to the washing position G2 after picking up the gasket in the initial position. Thus, the automation degree of the whole operation is improved.

[0066] Through the accurate discrimination and path planning of the sorting controller for the usable gasket and the recycled gasket, the manual intervention is effectively reduced, and the sorting efficiency and accuracy are improved. Combined with the continuous operation characteristics of the conveying belt, the movement of the sorting head between the stations is synchronized and coordinated, so as to ensure the stable operation tempo. The system can also perform statistical analysis according to the real-time collected defect data, optimize the front-end production process, and realize quality closed-loop control.

[0067] Referring to Figure 5 In another embodiment of the gasket cleaning device of the unit, the output end of the sorting identification module is connected to the input end of the sorting controller. The output end of the sorting controller is connected to the driving end of the sorting motor.

[0068] Referring to Figure 5 The gasket cleaning device of the diaphragm conveying unit further comprises a picking frame 54 fixed to the identification surface. The picking frame 54 has a picking surface capable of facing the working surface. The edge shape and size of the picking surface correspond to the edge shape and size of the gasket to be washed.

[0069] Referring to Figure 5 A plurality of suction cups 541 are uniformly distributed on the edge of the picking surface. The suction cups 541 are connected to the air suction and blowing supply system. When the air suction instruction is received by the supply system, the suction force is formed in the suction cup 541, so that the suction cup 541 sucks the gasket to be washed. When the air blowing instruction is received by the supply system, the blowing force is formed in the suction cup 541, so that the suction cup 541 places the gasket to be washed. The output end of the sorting controller is connected to the supply system.

[0070] Referring to Figure 5When the sorting controller sends the initial position instruction, the air supply system sends the suction instruction. When the sorting controller sends the cleaning position G2 instruction or the recycling position G3 instruction, the air supply system sends the blowing instruction after setting the moving time. When the input end of the sorting controller receives the sorting instruction, the output end of the sorting controller outputs the initial position instruction to the sorting motor, and the sorting head 53 stops at the initial position. The output end of the sorting controller sends the identification instruction to the sorting identification module.

[0071] If the input end of the sorting controller receives the available gasket information, the output end sends the cleaning position G2 instruction, so that the gasket to be cleaned that can be picked up by the sorting head 53 is placed in the cleaning position G2. If the input end of the sorting controller receives the recycling gasket information, the output end sends the recycling position G3 instruction, so that the gasket to be cleaned that can be picked up by the sorting head 53 is placed in the recycling position G3. The recycling quantity is obtained according to the recycling position G3 instruction.

[0072] Thus, the automation degree of the whole operation is improved, the classification, statistics and traceability management of the waste gasket are realized. The sorting controller records the result of each sorting action in real time, uploads the recycling quantity, frequency and corresponding batch information to the central control system, and provides data support for production decision. At the same time, the system can automatically trigger an alarm or a stop instruction according to the preset threshold value, so as to prevent the accumulation of abnormalities from affecting the overall yield. The design not only strengthens the intelligent level of the production line, but also effectively reduces the operation and maintenance cost, and further improves the operation continuity and stability.

[0073] In another embodiment of the gasket cleaning device of the unit, the sorting identification module is further configured to identify the dust density image of the surface of the gasket to be cleaned, and generate fine adjustment cleaning information if the dust density image is greater than a set threshold. The output end of the sorting identification module is connected to the input end of the cleaning controller. After receiving the fine adjustment cleaning information, the cleaning controller sends the first motor control information and the second motor control information from the output end of the cleaning controller.

The middle part of the boxing fixed frame 63 is located at the film output position H1 in the upper part of the output surface 66 of the output frame 61. The other end of the boxing fixed frame 63 is located at the input position H2 in the upper part of the input surface 67 of the input frame 62. Thus, the automation level is improved.

[0079] The boxing head can slide along the length direction of the boxing fixed frame 63 under the drive of the boxing motor. According to the film output position H1 instruction, the cleaned gasket can be picked up from the film output position H1 and placed in the output position H3. According to the input position H2 instruction, the supplementary gasket picked up at the input position H2 can be placed in the output position H3. Thus, the production efficiency and system coordination accuracy are improved, and the gasket cleaning process maintains dynamic balance in continuous operation.

[0080] The boxing controller is connected to the output end of the sorting controller to obtain the recycling quantity from the sorting controller. When the input end of the boxing controller receives the film output information, the output end of the boxing controller outputs the output position H3 instruction to the boxing motor.

[0081] According to the recycling quantity, the input quantity value in the input position H2 instruction is set. After the input end of the boxing controller receives the input information, the output end of the boxing controller outputs the input position H2 instruction to the boxing motor, and the input position H2 instruction includes the input quantity value.
