Description

Technical Field

[0001] This utility model relates to the field of polarizer conveying technology, specifically a guide-type display screen polarizer conveying and positioning device. Background Technology

[0002] The polarizer conveying device for LCD displays is a piece of equipment used to automatically convey and clean polarizers during the production process. It is mainly used in the bonding process of LCD manufacturing. The device uses an automated conveying system to transport polarizers from the storage location to the bonding station, and is equipped with a cleaning mechanism to prevent dust from adhering, ensuring bonding accuracy and product quality.

[0003] The aforementioned technologies have certain shortcomings in their application: when guiding and positioning the polarizer of the display screen, the conveying path of the polarizer needs to be constrained by a guiding mechanism to ensure that the polarizer moves stably along the preset path during the conveying process, avoiding lateral deviation and contact with the edge plate, which could damage the polarizer and cause "blockage" in the conveying route.

[0004] To address these issues, this invention provides a guide-type display screen polarizer conveying and positioning device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a guide-type display screen polarizer conveying and positioning device, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a guide-type display screen polarizer conveying and positioning device, including a conveying frame, in which several sheet conveying rollers are uniformly rotatably installed, and the rear roller shafts of the several sheet conveying rollers extend to the outside through bearings through the conveying frame and are synchronously conveyed through the same sprocket and chain transmission mechanism assembly. A guide component for adjustable guide spacing is installed inside the conveying frame, a drying component is installed on the top wall of the guide component, and a collection component for collecting the conveyed display screen polarizer and fixing it to the guide component is installed on the right side wall of the conveying frame. The guiding components include an adjustment mechanism and a guiding mechanism; The adjustment mechanism includes a servo motor fixedly installed on the front wall of the conveyor frame, a bidirectional lead screw rotatably installed in the middle of the inner wall of the conveyor frame, the power shaft of the servo motor passing through the conveyor frame and fixedly connected to the bidirectional lead screw through a bearing, slide blocks being screwed to the front and rear parts of the outer wall of the bidirectional lead screw, a movable frame being fixedly installed on the outer wall of the slide blocks, and a positioning rod being fixedly installed on the inner wall of the conveyor frame at the position corresponding to the slide block, the positioning rod sliding through the slide block; The guiding mechanism includes several guide frames fixedly installed on the top wall of the movable frame. The guide frames are arranged in a straight line and evenly distributed between adjacent sheet conveying rollers. The outer wall of each guide frame is provided with a mounting groove, and a guide roller is rotatably installed on the inner wall of each mounting groove.

[0007] The above technical solution uses a guide component to adjust the spacing in real time according to the specifications of the display screen polarizer, thereby forming a suitable conveying channel so that the display screen polarizer can be continuously positioned and conveyed along a predetermined route.

[0008] Furthermore, the top walls of several guide frames are fixedly installed to the bottom of the drying components. The drying components are fixedly installed with mounting frames through connectors. An infrared rangefinder is installed on the inner wall of the rear mounting frame, and a sensor is installed on the inner wall of the front mounting frame. The sensor is electrically connected to the infrared rangefinder and works in conjunction with it to monitor the distance between the adjustment mechanisms.

[0009] Through the above technical solution, the movement path of the adjustment mechanism can be monitored in real time by the cooperation of the infrared rangefinder and the sensor, so as to prevent excessive spacing.

[0010] Furthermore, limit rods are fixedly installed on both the left and right sides of the inner wall of the conveyor frame, and the outer walls of the limit rods slide through the moving frame.

[0011] The limiting rod, as described above, is mainly used to limit the path of the conveyor frame and provide overall support.

[0012] Furthermore, the collection assembly includes a placement platform fixedly installed on the right side wall of the conveyor frame. A baffle plate is fixedly installed on the right side of the top wall of the placement platform. A guide groove is opened in the middle of the top wall of the placement platform. A guide rod is fixedly installed on the inner wall of the guide groove. A slider is slidably installed on the outer wall of the guide rod. A guide plate is fixedly installed on the top wall of both sliders.

[0013] Through the above technical solution, the placement stage, guide plate and blocking plate are connected to form a placement space for placing polarizer, and the guide plate can move according to the slider sliding on the outer wall of the guide rod.

[0014] Furthermore, movable frames are fixedly installed on the bottom walls of both sliders, and the left ends of the two movable frames are fixedly connected to the right ends of the corresponding movable frames, which are used to adjust the specifications of the polarizer of the display screen by following the movement of the movable frames.

[0015] Through the above technical solution, when the moving frame is in motion, it drives the moving frame and the slider to move synchronously, which in turn causes the guide plate to move synchronously to adapt to the specifications of the polarizer.

[0016] Furthermore, the drying assembly includes a support rod fixedly installed on the top wall of the guide frame. The top of each support rod on the same side is fixedly installed with the same mounting plate. Several air outlet pipes are evenly installed inside the mounting plates, and the outer ends of the air outlet pipes on the same side are all connected to the same connecting pipe.

[0017] Through the above technical solution, the exhaust pipe blows hot air onto the surface of the polarizer to dry it.

[0018] Furthermore, the two adjacent connecting pipes are connected by the same conveying pipe, and the outer walls of the two conveying pipes are connected to an air inlet pipe, which is connected to an external hot air outlet device.

[0019] Through the above technical solution, the external hot air outlet device delivers hot air to the inlet pipe, delivery pipe and connecting pipe. Beneficial effects

[0020] This invention provides a guide-type polarizer conveying and positioning device for displays. Compared with the prior art, it has the following advantages: (1) The guide-type display polarizer conveying and positioning device, through the linkage of the guide component and the collection component, before the sheet conveying roller conveys the display polarizer, can adjust the spacing of the guide component to match the specifications of the display polarizer, so that the display polarizer can be guided and conveyed according to the predetermined route. With the rotation of the guide roller, it can prevent the display polarizer from being squeezed and bumped against the conveying frame. It has a good auxiliary effect on improving the conveying throughput and guiding protection. At the same time, the collection component moves in linkage with the adjustment of the guide component, so that the placement space constructed by the collection component matches the specifications of the display polarizer. When the display polarizer after being conveyed by the sheet conveying roller continuously falls into the placement space constructed by the collection component and is stacked, the positioning and guiding conveying of the display polarizer can be realized.

[0021] (2) The guide-type display polarizer conveying and positioning device, through the setting of the drying component, during the continuous conveying of the display polarizer, after cleaning, the liquid that may remain on the display polarizer is dried by the hot airflow of the drying component, which prevents the residual moisture from causing the polarizer to stick together when it is stacked later, and has an auxiliary effect on improving the cleanliness and dryness of the polarizer.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The working principle of this device is as follows: It is electrically connected to the servo motor 21, infrared rangefinder 210, and sensor 211 through an external controller and power supply. The spacing of the guide assembly 2 is adjusted according to the specifications of the polarizer of the display screen. The servo motor 21 drives the bidirectional lead screw 22 to rotate inside the conveyor frame 1. As the bidirectional lead screw 22 rotates, the slide block 24 located at the front and rear ends moves linearly along the outer walls of the bidirectional lead screw 22 and the positioning rod 23. The positioning rod 23 can limit the position of the slide block 24 to prevent it from flipping during the movement, thereby improving the accuracy of the movement path. The movement of the slide block 24 drives the moving frame 26 to slide along the outer wall of the limiting rod 25. The limiting rod 25 limits the movement path of the moving frame 26 and forms a stable support. The movable frame 26 synchronously drives the guide frame 27 and the guide roller 29 in the mounting groove 28 to approach each other in the gap between the sheet conveying rollers 5. At the same time, the guide frame 27 drives the support rod 31 and the mounting plate 32 to move synchronously, thereby driving the infrared rangefinder 210 and sensor 211 mounted on the mounting frame 212 to approach each other. The mounting frame 212 monitors the distance between the sensor 211 in real time, so that the distance between the movable frame 26 and the guide roller 29 is adapted to the polarizer of the display screen. As the moving frame 26 moves, it simultaneously drives the movable frame 46 to move at the bottom of the placement platform 41, and drives the slider 47 to slide along the inner wall of the guide groove 44 on the outer wall of the guide rod 45, so that the slider 47 drives the guide plate 43 to move closer to each other and match the specifications of the display screen polarizer. The guide frame 27 drives the support rod 31 and the mounting plate 32 to move closer together, so that the connecting pipe 34, the air outlet pipe 33, the conveying pipe 35 and the air inlet pipe 36 move closer together. The external drive device controls the sheet conveying roller 5 to start rotating, and through the linkage of the sprocket and chain transmission mechanism assembly 6, multiple sheet conveying rollers 5 rotate and convey at the same time. The display polarizer placed on the outer wall of the sheet conveying roller 5 can start to continuously convey. The external hot air outlet device continuously conveys hot air through the air inlet pipe 36 and the conveying pipe 35. The hot air is discharged through the connecting pipe 34 and the air outlet pipe 33 to the surface of the display polarizer for drying. After the display polarizer passes the surface of the sheet conveying roller 5, it is guided and conveyed along the rotation of the guide roller 29 and falls on the top wall of the placement platform 41 and contacts the baffle plate 42 and the guide plate 43. The conveyed display polarizer continuously falls between the baffle plate 42 and the guide plate 43 for stacking and placement, thereby completing the guiding and positioning conveying of the display polarizer.
