Description

Technical Field

[0001] The utility model relates to the field of automatic feeding of polarizing plates, and particularly to a polarizing plate magazine and a loading and unloading device. Background Art

[0002] The full name of a polarizing plate is a polarization light plate. The imaging of a liquid crystal display must rely on polarized light. All liquid crystals have two pieces of polarization light plates, front and back, closely attached to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of about 1 mm, so as to present an image on the liquid crystal display. Polarizing plates are mass-produced, and defects such as bubbles, unevenness, indentations, residual glue, and air streaks will be generated during the production or transportation process. These defects will seriously affect the product quality. Therefore, each polarizing plate needs to be fed and then transported for inspection before leaving the factory. Referring to the same type of equipment on the market, relatively speaking, the feeding speed is slow, and the polarizing plate is easily damaged to varying degrees during the feeding process.

[0026] Refer to Figures 1-4 , a polarizer magazine and loading and unloading device, comprising a magazine 1 and a transfer hand 2. Among them, a lifting mechanism 11 is arranged at the bottom of the magazine 1. The lifting mechanism 11 is fixedly connected to the magazine 1 through a support frame 111. The lower end of the lifting mechanism 11 is movably connected to a Z-axis motor 112. A horizontal drive mechanism 21 is arranged on the transfer hand 2. A vertical drive mechanism 22 is arranged on the mobile end of the horizontal drive mechanism 21. A suction cup mechanism 23 is arranged on the mobile end of the vertical drive mechanism 22. The suction cup mechanism 23 is provided with a plurality of suction cups 233 controlled by a plurality of suction cup control mechanisms 2331.

[0027] Refer to Figure 1 , further, the magazine 1 further includes a positioning mechanism 12. The positioning mechanism 12 is arranged at the upper part of the magazine 1. A bottom plate 123 is arranged at the lower end of the positioning mechanism 12. A positioner limit slot 121 is arranged above the bottom plate 123. A fixed rod 1211 is arranged at the lower end of the positioner limit slot 121 and is fixedly connected to the lifting mechanism 11. When the lifting mechanism 11 is lifted upward, the positioner limit slot 121 can be lifted upward. A polarizer is placed above the positioner limit slot 121. Thus, the polarizer placed above can be lifted upward to complete the feeding process.

[0028] Refer to Figure 1 , a positioner 122 is movably connected in the positioner limit slot 121. The lower end of the positioner 122 contacts the bottom plate 123. The middle part is arranged inside the positioner limit slot 121. The upper end protrudes from the positioner limit slot 121. The positioner 122 can move through a slider on the chute in the positioner limit slot 121, so as to change the positions of a plurality of positioners 122, and thus adapt to polarizers of different sizes.

[0029] Refer to Figure 1, Further, the silo 1 further includes a rising detection mechanism 13, wherein the rising detection mechanism 13 is arranged at one side edge of the bottom plate 123, and its height is higher than that of the positioner 122. A pair of photoelectric components 131 are arranged at the top of the rising detection mechanism 13. The pair of photoelectric components 131 emit pair of photoelectric beams, and determine whether the polarizing plate is in the correct position according to the reflected signal. If there is a foreign object or the position of the polarizing plate deviates, an error is reported, and the entire device stops working and waits for manual inspection and recovery.

[0030] Refer to Figure 1 , Further, the silo 1 further includes a double-sheet detection mechanism 14, wherein the double-sheet detection mechanism 14 is arranged at the edge of the bottom plate 123 and inside the corner closer to the side where the rising detection mechanism 13 is located. Its height is higher than that of the positioner 122. An induction signal component 141 is arranged at the top of the double-sheet detection mechanism 14. The induction signal component 141 is used to judge whether there is a situation where two polarizing plates adsorbed by the transfer hand 2 are stacked. If such a situation occurs, an error is reported, and the entire device stops working and waits for manual inspection and recovery.

[0031] Refer to Figures 2-4 , Further, the suction cup mechanism 23 further includes suction cup limit grooves 231, a pressing plate 232, and a pressing plate control mechanism 2321. Among them, several horizontal and vertical suction cup limit grooves 231 are arranged on the suction cup mechanism 23. The upper ends of several suction cup control mechanisms 2331 are arranged in the corresponding suction cup limit grooves 231, and the lower ends are connected to the suction cups 233. The suction cup control mechanism 2331 can move in the suction cup limit groove 231 where it is located. Since the polarizing plates have different sizes, the suction cups 233 controlled by the suction cup control mechanisms 2331 that can move in the suction cup limit grooves 231 can change different positions according to needs, so as to adapt to polarizing plates of different sizes.

[0032] Refer to Figures 2-4 , Further, the pressing plate 232 is located at the lower end of the suction cup mechanism 23, and suction cup limit grooves 231 corresponding to the suction cup mechanism 23 are also formed thereon. The lower ends of the suction cup control mechanisms 2331 passing through the suction cup limit grooves 231 provided on the pressing plate 232 are provided with suction cups 233, so that the suction cup control mechanisms 2331 will not be affected by the pressing plate 232 when changing positions.

[0033] A plurality of platen control mechanisms 2321 are provided on the platen 232. One end of the platen control mechanism 2321 is fixedly connected to the platen 232, and the other end is fixedly connected to the suction cup mechanism 23. The platen 232 is movably connected to the suction cup mechanism 23 through the platen control mechanism 2321. After the transfer hand 2 places the polarizer on the film tearing and pasting platform 3, the suction cup mechanism 23 no longer adsorbs the polarizer, and the polarizer is disconnected from the suction cup mechanism 23. At the same time, the platen 232 moves downward under the control of the platen control mechanism 2321 to press down the polarizer and separate it from the transfer hand 2 for subsequent operations.

[0034] Embodiment 1: First, manually pull all the positioners 122 to the maximum position, then place the polarizer on the magazine 1, adjust the position of the positioners 122 so that they can firmly clamp the polarizer, and then the device can automatically complete the subsequent work.

[0035] Driven by the Z-axis motor 112 of the lifting mechanism 11, the magazine 1 raises the position of the support frame 111, and further raises the position of the fixed rod 1211 fixedly connected to the support frame 111, thereby completing the raising of the position of the positioner limit groove 121 and completing the loading operation.

[0036] During the loading process, the rising detection mechanism 13 detects whether the loading of the polarizer is in the normal position. If there is a foreign object or the position of the polarizer is deviated, an error is reported, and the entire device stops working and waits for manual inspection and recovery.

[0037] Under the cooperation of the horizontal drive mechanism 21 and the vertical drive mechanism 22, the transfer hand 2 moves the suction cup mechanism 23 to directly above the corresponding polarizer. The suction cup limit groove is provided on the suction cup mechanism 23. The upper ends of a plurality of suction cup control mechanisms 2331 are arranged in the corresponding suction cup limit grooves 231, and the lower ends are connected to the suction cups 233. The suction cup control mechanism 2331 can move within its corresponding suction cup limit groove 231. According to the different sizes of the polarizers, the suction cup control mechanism 2331 is moved to the required position within the suction cup limit groove 231 to adapt to the polarizer to be moved. After the suction cup mechanism 23 completes the action of adsorbing the polarizer, the double-sheet detection mechanism 14 is used to determine whether the polarizer adsorbed by the transfer hand 2 is stacked in two sheets. If this situation occurs, an error is reported, and the entire device stops working and waits for manual inspection and recovery. If there is no problem, the device continues to run automatically. The transfer hand 2 places the polarizer in the required position, then the platen 232 presses down, the suction cup mechanism 23 cancels the adsorption, and moves to the initial position, waiting for the next transportation of the polarizer.
