Description

Technical Field

[0001] This utility model relates to the field of polarizing film disassembly technology, and in particular to an LCD polarizing film disassembly device. Background Technology

[0002] An LCD polarizing film removal device is a specialized piece of equipment used to separate the polarizing film from the LCD glass substrate. Its core function is to soften the adhesive between the polarizing film and the glass substrate and achieve efficient separation of the two through specific technical means (such as hot air heating and mechanical separation), while avoiding damage to the glass substrate or the polarizing film.

[0003] Most existing disassembly devices only use a simple mechanical force separation method, such as direct pulling or prying. This method is prone to damaging the polarizing film and glass base, resulting in tearing or breaking of the polarizing film or cracking of the glass base. Utility Model Content

[0004] The purpose of this invention is to provide an LCD polarizing film disassembly device, which improves the quality of the disassembled product and solves the problem of poor product quality after disassembly in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An LCD polarizing film disassembly device includes a base, conveyor belts on both inner walls of the base, multiple carrier frames fixedly connected at equal intervals on the surface of the conveyor belts, a housing fixedly connected to the upper end of the base, and multiple heating lamps fixedly connected to the top of the housing; a bracket, fixedly mounted on the upper end of the base, a movable plate slidably connected between the inner walls of the bracket, a cavity provided inside the movable plate, multiple suction cups fixedly connected at equal intervals at the lower end of the movable plate, the suction cups communicating with the cavity, a movable frame slidably connected inside the movable plate, a wire fixedly connected between the inner walls of the movable frame, grooves provided on both inner walls of the bracket, a collection frame slidably connected between two of the grooves, and an electric push rod II fixedly connected inside the side wall of the bracket, the output end of the electric push rod II fixedly connected to the side wall of the collection frame.

[0007] Preferably, two rollers are arranged between the inner walls on both sides of the base, the conveyor belt is sleeved on the outside of the two rollers, a drive motor is fixedly connected inside the side wall of the base, and the output end of the drive motor is fixedly connected to one of the roller side walls.

[0008] Preferably, the conveyor belt surface is provided with a plurality of holes at equal intervals, a reflector is fixedly connected to the lower end of the bearing frame, a horizontal plate is fixedly connected between the inner walls of the two sides of the base, and a photoelectric sensor is fixedly connected to the upper end of the horizontal plate.

[0009] Preferably, an electric actuator is fixedly connected to the upper end of the bracket, the output end of the electric actuator is fixedly connected to the upper end of the movable plate, and two guide rods are fixedly connected to the upper end of the movable plate, the guide rods being slidably connected through the upper end of the bracket.

[0010] Preferably, a screw is rotatably connected inside the movable plate, the screw is threadedly connected to the movable frame, a motor is fixedly connected to the side wall of the movable plate, and the output end of the motor is fixedly connected to the end of the screw through a coupling.

[0011] Preferably, an air pump is fixedly connected to the upper end of the support, and a pipe is fixedly connected between the input end of the air pump and the interior of the chamber. The pipe is slidably connected through the side wall of the support, and the end of the pipe is fixedly connected to the interior of the side wall of the movable plate.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. Heating the glass base and polarizing film with a heating lamp can soften the adhesive used to attach the polarizing film evenly. The internal temperature of the housing is monitored in real time by a temperature sensor to ensure that the adhesive reaches the optimal softening state. This prevents the adhesive from becoming too hard and difficult to separate due to insufficient heating, and also prevents the glass base or polarizing film from being damaged due to excessive heating, thus providing good conditions for subsequent disassembly.

[0014] 2. The suction cup uses negative pressure to evenly adsorb the polarizing film. When the electric push rod pulls the movable plate upward to lift the polarizing film, it ensures that the polarizing film is subjected to uniform force and will not be deformed or damaged due to localized force concentration. At the same time, this gentle lifting method also reduces the impact and damage to the glass base, ensuring the integrity of the glass base and facilitating subsequent reuse or further processing of the glass base.

[0015] 3. Driven by the motor, the wire slides smoothly between the glass base and the polarizing film, which can apply the separation force evenly. This avoids the polarizing film from tearing, breaking, or leaving residue on the glass base due to excessive or insufficient local force, ensuring that the polarizing film is completely separated from the glass base and improving the quality of the disassembled product.

[0016] 4. The controller precisely controls the second electric push rod to ensure that the collection frame is accurately positioned at the lower end of the movable plate. This ensures that the polarizing film can accurately fall into the collection frame after the negative pressure suction disappears, preventing the polarizing film from falling outside the collection frame and causing damage or loss. This ensures the integrity and safety of the collected polarizing film. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5An LCD polarizing film disassembly device includes a base 001, with conveyor belts 103 arranged on the inner walls of both sides of the base 001. Multiple support frames 105 are fixedly connected at equal intervals to the surface of the conveyor belts 103. A housing 109 is fixedly connected to the upper end of the base 001, and multiple heating lamps 110 are fixedly connected to the top of the housing 109. A bracket 002 is fixedly mounted on the upper end of the base 001. A movable plate 201 is slidably connected between the inner walls of both sides of the bracket 002. A chamber 202 is provided inside the movable plate 201. Multiple suction cups 203 are fixedly connected at equal intervals to the lower end of the movable plate 201, communicating with the chamber 202. A movable frame 204 is slidably connected inside the movable plate 201, and wires 205 are fixedly connected between the inner walls of both sides of the movable frame 204. Both sides of the bracket 002 have grooves 212 on their inner walls. A collection frame 213 is slidably connected between the two grooves 212. An electric push rod 214 is fixedly connected to the inside of the side wall of the bracket 002. The output end of the electric push rod 214 is fixedly connected to the side wall of the collection frame 213. A contact sensor is fixedly connected to the inner wall of one of the grooves 212. A temperature sensor is fixedly connected to the inner wall of the housing 109. A controller is fixedly connected inside the base 001. The temperature sensor, contact sensor, heating lamp 110, and electric push rod 214 are all electrically connected to the controller. The lower middle section of the bearing frame 105 is fixedly connected to the surface of the conveyor belt 103. The thread 205 is made of polyester. A collection box with a sponge pad is fixedly connected inside the base 001 and placed on one side of the base 001. The operator then polarizes the light. After the LED glass substrate is cleaned, it is placed inside the upper part of the support frame 105. The slot at the upper end of the support frame 105 is the same size as the LED glass substrate. Simultaneously, the polarizing film protrudes horizontally above the upper end of the support frame 105. Then, the conveyor belt 103 operates, moving the support frame 105 with the glass substrate inside the housing 109. The conveyor belt 103 stops operating, and the controller then turns on the heating lamp 110 to heat the glass substrate and the polarizing film adhered to its upper end. Simultaneously, the controller monitors the temperature inside the housing 109 using a temperature sensor. After the glass substrate and polarizing film are heated, the support frame 105 moves to the lower end of the bracket 002, and then the movable plate 201 moves... The movable frame 204 slides downwards, causing its lower end to fit against the upper end of the support frame 105. At this point, the wire 205 is located in the gap between the glass base and the polarizing film, and the lower ends of the multiple suction cups 203 at the lower end of the movable plate 201 are tightly fitted against the polarizing film at the upper end of the glass base. A negative pressure suction force is generated inside the chamber 202, which adsorbs the polarizing film through the multiple suction cups 203. Subsequently, the movable frame 204 drives the wire 205 to move, and the wire 205 slides through one end of the gap between the glass base and the polarizing film to separate them. After the wire 205 slides out from the other end of the gap, the movable plate 201 slides upwards, and at the same time, the suction cups 203 drive the polarizing film to slide upwards, disassembling the polarizing film from the upper end of the glass base. Then, the conveyor belt 103 operates.This causes the support frame 105, containing the glass base, to move circumferentially. At this time, the glass base inside the support frame 105 falls into the collection box on one side of the base 001. Simultaneously, the controller opens the second electric push rod 214, whose output pulls the collection frame 213 to slide. When the collection frame 213 contacts the contact sensor, the controller closes the second electric push rod 214. At this point, the collection frame 213 is located at the lower end of the movable plate 201. Subsequently, the negative pressure suction inside the chamber 202 disappears, and the polarizing film falls into the collection frame 213. During this process, when the pre-set time program in the controller expires, the controller opens the second electric push rod 214, whose output pushes the collection frame 213 to slide, causing the collection frame 213 to slide out from the lower end of the movable plate 201. Even after the output of the second electric push rod 214 extends to its maximum distance, a portion of the collection frame 213 remains inside the groove 212.

[0025] Two rollers 101 are arranged between the inner walls of the two sides of the base 001. The conveyor belt 103 is sleeved on the outside of the two rollers 101. A drive motor 102 is fixedly connected inside the side wall of the base 001. The output end of the drive motor 102 is fixedly connected to the side wall of one of the rollers 101. The output end of the drive motor 102 drives one of the rollers 101 to rotate. Then, through the cooperation of the other roller 101, the conveyor belt 103 is operated. The drive motor 102 is electrically connected to the controller.

[0026] Multiple holes 104 are equidistantly arranged on the surface of the conveyor belt 103. A reflector 106 is fixedly connected to the lower end of the bearing frame 105. A horizontal plate 107 is fixedly connected between the inner walls on both sides of the base 001. A photoelectric sensor 108 is fixedly connected to the upper end of the horizontal plate 107. The photoelectric sensor 108 is a reflective photoelectric sensor. The photoelectric sensor 108 is electrically connected to the controller. The holes 104 correspond to the reflector 106. When the reflector 106 moves to the laser emitting end of the photoelectric sensor 108, the reflector 106 reflects the laser of the photoelectric sensor 108, and the photoelectric sensor 108 receives the reflected light and transmits the signal to the controller.

[0027] An electric actuator 206 is fixedly connected to the upper end of the bracket 002. The output end of the electric actuator 206 is fixedly connected to the upper end of the movable plate 201. Two guide rods 207 are fixedly connected to the upper end of the movable plate 201. The guide rods 207 are slidably connected to the upper end of the bracket 002. The movable plate 201 is pulled or pushed up and down by the output end of the electric actuator 206. The electric actuator 206 is electrically connected to the controller.

[0028] A screw 208 is rotatably connected inside the movable plate 201. The screw 208 is threadedly connected to the movable frame 204. A motor 209 is fixedly connected to the side wall of the movable plate 201. The output end of the motor 209 is fixedly connected to the end of the screw 208 through a coupling. The output end of the motor 209 drives the screw 208 to rotate. The screw 204 slides through the threaded engagement between the screw 208 and the movable frame 204. The motor 209 is electrically connected to the controller.

[0029] An air pump 210 is fixedly connected to the upper end of the bracket 002. A pipe 211 is fixedly connected between the input end of the air pump 210 and the inside of the chamber 202. The pipe 211 is slidably connected through the side wall of the bracket 002. The end of the pipe 211 is fixedly connected to the inside of the side wall of the movable plate 201. The air pump 210 is electrically connected to the controller. The air pump 210 draws air into the inside of the chamber 202 through the pipe 211, so that a suction airflow is generated inside the chamber 202.

[0030] In this invention, the operator places the LED glass base with polarizing film, after surface cleaning, inside the upper end of the support frame 105, ensuring that the polarizing film protrudes horizontally above the upper end of the support frame 105. Then, the controller controls the drive motor 102 to start, and its output drives one of the rollers 101 to rotate. With the cooperation of the other roller 101, the conveyor belt 103 starts to operate, moving and conveying the support frame 105. During the movement of the support frame 105, the reflector 106 moves synchronously. When one of the reflectors 106 moves to the laser emitting end of the photoelectric sensor 108, the reflector 106 reflects the laser. The photoelectric sensor 108 receives the reflected light and transmits the signal to the controller. The controller then controls the drive motor 102 to stop, and the conveyor belt 103 stops operating. At this time, the support frame 105 with the glass base moves into the housing 109.

[0031] The controller turns on the heating lamp 110 to heat the glass base and the polarizing film adhered to its upper end. At the same time, the temperature sensor monitors the temperature inside the housing 109 in real time. During this heating process, when the time program preset inside the controller is reached, the controller controls the drive motor 102 to start again and continue to transport the carrier frame 105.

[0032] After the glass base and polarizing film are heated, the support frame 105 moves to the lower end of the bracket 002. The controller controls the operation of the electric push rod 206, whose output end pushes the movable plate 201 to slide downward. When the output end of the electric push rod 206 extends to its maximum stroke, the lower end of the movable frame 204 is in contact with the upper end of the support frame 105. At this time, the wire 205 is exactly located in the gap between the glass base and the polarizing film. At the same time, the lower ends of the multiple suction cups 203 at the lower end of the movable plate 201 are in close contact with the polarizing film at the upper end of the glass base. The controller then shuts off the electric push rod 206.

[0033] The controller turns on the air pump 210, which draws air into the chamber 202 through the pipe 211, creating a suction airflow inside the chamber 202. The negative pressure suction uses multiple suction cups 203 to adsorb the polarizing film. Then, the controller turns on the motor 209, whose output drives the screw 208 to rotate. Through the threaded engagement between the screw 208 and the movable frame 204, the movable frame 204 slides, causing the wire 205 to move. The wire 205 slides from one end of the gap between the glass base and the polarizing film to the two, achieving separation. After the wire 205 slides out from the other end of the gap, the controller controls the electric push rod 206 to operate in the opposite direction. Its output pulls the movable plate 201 to slide upward, and the suction cups 203 then drive the polarizing film to slide upward, removing the polarizing film from the upper end of the glass base.

[0034] The controller then controls the drive motor 102 to operate again, causing the conveyor belt 103 to continue moving. The carrier frame 105, which holds the glass base, moves circumferentially. Due to gravity, the glass base inside the carrier frame 105 falls from inside the carrier frame 105 into a collection box pre-placed on one side of the base 001, which has a sponge pad fixed inside. At the same time, the controller activates the second electric push rod 214, whose output end pulls the collection frame 213 to slide. When the collection frame 213 contacts the contact sensor, the controller closes the second electric push rod 214. At this time, the collection frame 213 is located at the lower end of the movable plate 201. Subsequently, the controller controls the air pump 210 to stop, causing the negative pressure suction inside the chamber 202 to disappear, and the polarizing film falls into the collection frame 213. During this process, when the time program preset inside the controller is reached again, the controller activates the second electric push rod 214, whose output end pushes the collection frame 213 to slide out from the lower end of the movable plate 201.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
