Description

Technical Field

[0001] The utility model relates to the technical field of polarizer attachment, in particular to a polarizer attachment device. Background Art

[0002] Polarizer attachment is a key process in the production of liquid crystal display panels. With the continuous advancement of display technology, the attachment process places increasingly higher demands on equipment. Based on this, a polarizer attachment device based on PLC control has been designed. This device utilizes a carrier tape in conjunction with an adhesive plate to adsorb the polarizer, achieving excellent imaging results and meeting the requirements for high-precision attachment of the LCD glass substrate and the polarizer. It effectively avoids direct contact between the polarizer and the polyurethane adhesive stick, which can lead to linear bubbles and adhesive overflow during attachment. It also addresses the problem of uneven polarizer attachment caused by traditional vacuum suction plates, resulting in imaging results that do not meet high-precision attachment requirements. This device has a simple structure, good attachment quality, and high positioning accuracy.

[0003] The polarizer attachment imaging effect in the polarizer attachment device in the existing technology is average, which meets the requirements of LCD glass. It cannot avoid direct contact between the polarizer and the polyurethane glue stick, resulting in problems such as linear bubbles and glue overflow during attachment. In addition, the traditional suction plate vacuum adsorption causes the polarizer to be uneven. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a polarizer attachment device to solve the technical problems that direct contact between the polarizer and the polyurethane glue stick causes linear bubbles and glue overflow during attachment, and the traditional vacuum adsorption of the suction plate causes uneven polarizer.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a polarizer attaching device, comprising a suspension mechanism, wherein the bottom end of the suspension mechanism is movably connected to a sliding mechanism, a second driving device is arranged inside the sliding mechanism, the bottom end of the sliding mechanism is movably connected to a carrier control mechanism that cooperates with the second driving device, a first driving device is arranged at one end of the carrier control mechanism, the bottom end of the carrier control mechanism is movably connected to an attaching mechanism, a first carrier roller is arranged at one end of the carrier control mechanism, and a second carrier roller is arranged at one end of the carrier control mechanism.

[0006] By adopting the above technical solution, when in use, the power is turned on, and the external user starts the control device, and the suspension mechanism is fixed by the brackets provided at the four corners to prevent shaking or falling off during the overall operation;

[0007] After activation, the sliding mechanism moves along the guide rail provided at the bottom of the suspension mechanism. When it reaches the appropriate position, the second driving device inside the sliding mechanism is activated, which then pushes the carrier tape control mechanism fixed at the bottom to move downward. After moving to the appropriate position, it stops. At this time, the carrier tape controlled by the first and second carrier tape rollers provided at the bottom of the carrier tape control mechanism also descends.

[0008] Because there is an adhesive plate on the bottom of the carrier tape, when the carrier tape moves down, it will adhere to the polarizer, thereby controlling the displacement of the polarizer;

[0009] Then, the control device controls the second driving device to retract, controls the carrier belt control mechanism to move upward, and makes the distance with the sliding mechanism close, and then moves through the electric guide rail above the sliding mechanism that cooperates with the suspension mechanism;

[0010] After moving to the appropriate position, the second driving device is started again, pushing the carrier tape control mechanism downward, and then the carrier tape retracting mechanism moves upward under the action of the cylinder provided inside it, so that the second carrier tape roller provided at the bottom thereof moves upward, that is, drives one end of the carrier tape controlled by it to move upward, making the entire carrier tape tight, and at the same time making the carrier tape pressing plate provided at the bottom end of the attaching mechanism fit the carrier tape more closely;

[0011] The carrier tape controlled by the first and second carrier rollers forms a Z-shape when passing through the attaching mechanism, that is, one end of the carrier tape passes through the bottom end of the carrier pressure plate and then passes through the top end of the fourth rubber roller provided on the attaching mechanism. This arrangement ensures that the attaching mechanism has good attaching quality and high positioning accuracy when attaching the polarizer on the carrier tape.

[0012] Through the above structure, the device uses a carrier tape in conjunction with an adhesive plate to adsorb the polarizer, which has good imaging effect and meets the high-precision attachment requirements of the LCD glass substrate and the polarizer. It effectively avoids direct contact between the polarizer and the polyurethane glue stick, which leads to problems such as linear bubbles and glue overflow during attachment. It also solves the problem that the traditional vacuum suction plate adsorbs the polarizer unevenly, resulting in the imaging effect not meeting the high-precision attachment requirements. The device has a simple structure, good attachment quality, and high positioning accuracy.

[0013] Furthermore, a second rubber roller is provided at one end of the carrier control mechanism, and a first rubber roller is provided at one end of the carrier control mechanism.

[0014] By adopting the above technical solution, the carrier tape can be further tightened and controlled by the second rubber roller and the first rubber roller to prevent the carrier tape from falling when laminating the polarizer.

[0015] Furthermore, two groups of third rubber rollers are provided at one end of the attaching mechanism, and a fourth rubber roller is fixed on the outside of the attaching mechanism.

[0016] By adopting the above technical solution, the two sets of third rubber rollers can keep the carrier tape in a taut state when passing through the attaching mechanism, thereby better controlling the attaching of the polarizer.

[0017] Furthermore, a cylinder is provided inside the carrier tape retracting mechanism, and brackets are provided at the four corners of the suspension mechanism.

[0018] By adopting the above technical solution, the shrinking mechanism moves upward under the action of the cylinder provided inside the shrinking mechanism, so that the second carrier roller provided at the bottom end thereof moves upward.

[0019] Furthermore, a carrier tape pressing plate is provided at the bottom end of the attaching mechanism, and a cylinder cooperating with the carrier tape pressing plate is provided inside the attaching mechanism.

[0020] By adopting the above technical solution, the carrier tape controlled by the carrier roller and the second carrier roller presents a Z shape when passing through the attaching mechanism, which can ensure that when the attaching mechanism attaches the polarizer on the carrier tape, the attaching quality is good and the positioning accuracy is high.

[0021] Furthermore, the first driving device is fixed to the carrier control mechanism by a plurality of sets of screws, and a guide rail cooperating with the attachment mechanism is provided on the outer side of the carrier control mechanism.

[0022] By adopting the above technical solution, when attaching the polarizer, the attachment of the polarizer can be reinforced by moving the attachment mechanism to prevent loose attachment.

[0023] In summary, the utility model mainly has the following beneficial effects: the utility model slides on the bottom end of the suspension mechanism through the electric guide rail through the sliding mechanism, and then the carrier control mechanism movably connected to the bottom end of the sliding mechanism is lowered to a suitable position through the second driving device, and then the polarizer is adsorbed by controlling the tensioned carrier between the first carrier roller and the second carrier roller, and the adhesive plate matched with the bottom end of the carrier, and then the sliding mechanism is controlled by the control device to move on the suspension mechanism until it reaches the suitable position, and the first driving device rotates the screw rod to make the attachment mechanism descend to align the polarizer controlled by the carrier below with the position to be attached, and then the first driving device is used to The device starts and drives the attaching mechanism to move, and then the polarizer is attached by the first carrier roller and the second carrier roller arranged at the bottom of the attaching mechanism in conjunction with the first rubber roller, the second rubber roller, the third rubber roller, the fourth rubber roller and the carrier pressure plate. The device uses the carrier tape in conjunction with the adhesive plate to adsorb the polarizer, which has good imaging effect and meets the high-precision attachment requirements of the LCD glass substrate and the polarizer. It effectively avoids direct contact between the polarizer and the polyurethane glue stick, which leads to linear bubbles and glue overflow during attachment, and solves the problem of uneven polarizer adsorption by the traditional suction plate vacuum, which leads to the imaging effect not meeting the high-precision attachment requirements. The device has a simple structure, good attachment quality and high positioning accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A polarizer attaching device, such as Figure 1-5 As shown, it includes a suspension mechanism 1, the bottom end of the suspension mechanism 1 is movably connected to a sliding mechanism 2, a second driving device 13 is provided inside the sliding mechanism 2, and the bottom end of the sliding mechanism 2 is movably connected to a carrier control mechanism 14 that cooperates with the second driving device 13, wherein the sliding mechanism 2 moves along the guide rail provided at the bottom end of the suspension mechanism 1 and cooperates with it. When it moves to a suitable position, the second driving device 13 inside the sliding mechanism 2 is started, and then pushes the carrier control mechanism 14 fixed at the bottom end to move downward, and stops after moving to a suitable position. At this time, the carrier controlled by the first carrier roller 4 and the second carrier roller 7 provided at the bottom end of the carrier control mechanism 14 will also descend. Because an adhesive plate is provided on the bottom surface of the carrier, when the carrier moves downward, it will adhere to the polarizer, thereby controlling the displacement of the polarizer;

[0033] Exemplarily, a first driving device 3 is provided at one end of the carrier control mechanism 14, and an attaching mechanism 15 is movably connected to the bottom end of the carrier control mechanism 14. A first carrier roller 4 is provided at one end of the carrier control mechanism 14, wherein the second driving device 13 is controlled to retract by the control device to control the carrier control mechanism 14 to move up and get close to the distance with the sliding mechanism 2, and then move through the electric guide rail above the sliding mechanism 2 that cooperates with the suspension mechanism 1. When it moves to a suitable position, the second driving device 13 is started again to push the carrier control mechanism 14 down, and then the carrier retracting mechanism 6 moves up under the action of the cylinder arranged inside it, so that the second carrier roller 7 arranged at its bottom end moves up, that is, drives one end of the carrier belt it controls to move up, so that the entire carrier belt is tightened, and at the same time, the carrier belt pressing plate 12 arranged at the bottom end of the attaching mechanism 15 can fit the carrier belt more closely;

[0034] For example, a second carrier roller 7 is provided at one end of the carrier control mechanism 14. A second rubber roller 9 is provided at one end of the carrier control mechanism 14, and a first rubber roller 8 is provided at one end of the carrier control mechanism 14. The carrier tape controlled by the first carrier roller 4 and the second carrier roller 7 presents a Z-shape when passing through the attaching mechanism, that is, one end of the carrier tape passes through the bottom end of the carrier pressure plate 12 and then passes through the top end of the fourth rubber roller 11 provided on the attaching mechanism 15. This arrangement ensures that when the attaching mechanism 15 attaches the polarizer on the carrier tape, the attaching quality is good and the positioning accuracy is high.

[0035] In some examples, two sets of third rubber rollers 10 are provided at one end of the attachment mechanism 15, and a fourth rubber roller 11 is fixed to the outside of the attachment mechanism 15. A cylinder is provided inside the carrier tape retraction mechanism 6, and brackets 5 are provided at the four corners of the suspension mechanism 1. When activated by an external user through a control device, the suspension mechanism 1 is fixed by the brackets 5 provided at the four corners to prevent shaking or falling off during the overall operation.

[0036] The working principle of the present invention is as follows: when in use, the power is turned on, and the user starts the control device. The suspension mechanism 1 is fixed by the brackets 5 provided at the four corners to prevent shaking or falling off during the overall operation.

[0037] After starting, the sliding mechanism 2 will move along the guide rail provided at the bottom of the suspension mechanism 1 and the guide rail that matches it. When it moves to the appropriate position, the second driving device 13 inside the sliding mechanism 2 is activated, and then the carrier belt control mechanism 14 fixed at the bottom is pushed downward. After moving to the appropriate position, it stops. At this time, the carrier belt controlled by the first carrier belt roller 4 and the second carrier belt roller 7 provided at the bottom of the carrier belt control mechanism 14 will also descend.

[0038] Because there is an adhesive plate on the bottom of the carrier tape, when the carrier tape moves down, it will adhere to the polarizer, thereby controlling the displacement of the polarizer;

[0039] Then, the control device controls the second driving device 13 to retract, controls the carrier control mechanism 14 to move upward, and makes the distance with the sliding mechanism 2 close, and then moves through the electric guide rail above the sliding mechanism 2 that cooperates with the suspension mechanism 1;

[0040] After moving to the appropriate position, the second driving device 13 is started again, pushing the carrier tape control mechanism 14 downward, and then the carrier tape retracting mechanism 6 moves upward under the action of the cylinder provided therein, so that the second carrier tape roller 7 provided at its bottom end moves upward, that is, it drives one end of the carrier tape controlled by it to move upward, making the entire carrier tape tight, and at the same time making the carrier tape pressing plate 12 provided at the bottom end of the attaching mechanism 15 fit the carrier tape more closely;

[0041] The carrier tape controlled by the first carrier roller 4 and the second carrier roller 7 presents a Z-shape when passing through the attaching mechanism, that is, one end of the carrier tape passes through the bottom end of the carrier tape pressing plate 12 and then passes through the top end of the fourth rubber roller 11 provided on the attaching mechanism 15. This arrangement ensures that when the attaching mechanism 15 attaches the polarizer on the carrier tape, the attaching quality is good and the positioning accuracy is high;

[0042] Specifically, the second driving device 13 and the first driving device 3 are servo motors that rotate to drive the sliders disposed outside thereof to move, thereby achieving a certain driving effect;

[0043] Through the above structure, the device uses a carrier tape in conjunction with an adhesive plate to adsorb the polarizer, which has good imaging effect and meets the high-precision attachment requirements of the LCD glass substrate and the polarizer. It effectively avoids direct contact between the polarizer and the polyurethane glue stick, which leads to problems such as linear bubbles and glue overflow during attachment. It also solves the problem that the traditional vacuum suction plate adsorbs the polarizer unevenly, resulting in the imaging effect not meeting the high-precision attachment requirements. The device has a simple structure, good attachment quality, and high positioning accuracy.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
