Technical Field

[0001] The utility model relates to the technical field of film separation, in particular to a heating stripping device. Background Art

[0002] At present, in the LCM production process, the FPC of the product is bent and misaligned, or the FPC is peeled off from the iron frame when the backlight is disassembled. Due to the high temperature, the adhesive is difficult to separate. The conventional method is to heat the heating table to 70℃ (the temperature is too high for hands to bear), and then peel it off hard. Since the LCD is under great force, this will cause the LCD to break and LCD red and blue spots. Utility Model Content

[0003] The main purpose of the utility model is to provide a heating peeling device, which aims to increase the heating temperature, reduce the viscosity of the high-temperature glue, reduce the difficulty of separating the LCD carrier and the FPC, and reduce the force on the LCD carrier, thereby avoiding the breakage of the LCD carrier and the red and blue spots of the LCD.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a heating peeling device, comprising:

[0005] A carrier for carrying an LCD carrier board with an FPC bonded thereto; and

[0006] A peeling mechanism, comprising a blade and a heating portion capable of heating the blade, wherein the blade is located above the carrier platform;

[0007] The blade and the carrier platform have a relative up and down movable stroke, and a relative lateral movable stroke. In the up and down movable stroke, the blade can contact the LCD carrier board with FPC adhered to the carrier platform. In the lateral movable stroke, the blade can peel off the FPC adhered to the LCD carrier board on the carrier platform.

[0008] In one embodiment, the blade can be movably arranged up and down, so that the blade and the supporting platform have a relative up and down movable stroke;

[0009] The heating and peeling device also includes a blade driving device for driving the blade to move up and down.

[0010] In one embodiment, the heating portion comprises a heating block, and the blade is mounted on a lower end of the heating block.

[0011] In one embodiment, the heating block is provided with a mounting hole, and the mounting hole is used for mounting a heating element so as to heat the blade through the heating block; and / or,

[0012] The lower end of the mounting block is provided with a mounting groove, and the upper end of the blade is mounted to the mounting groove.

[0013] In one embodiment, an arc-shaped groove is formed on one side of the heating block at a position adjacent to the blade.

[0014] In one embodiment, the blade is provided with an anti-stick coating; and / or,

[0015] The blade is arranged in an inclined manner.

[0016] In one embodiment, the carrier is arranged to be movable in the transverse direction, so that the blade and the carrier have a relative transverse movable stroke;

[0017] The heating and peeling device further comprises a stage driving device, which is drivingly connected to the carrying platform to drive the carrying platform to move horizontally.

[0018] In one embodiment, a limiting portion is disposed on the carrying platform, and the limiting portion is used to limit the LCD carrying plate.

[0019] In one embodiment, the limiting portion includes a vacuum adsorption hole provided on the supporting platform.

[0020] In one embodiment, at least one supporting portion is protrudingly provided on the supporting platform.

[0021] The technical solution of the utility model places an LCD carrier board covered with FPC on a carrier platform, uses a heating part to provide heat to a blade, so that the temperature of the blade rises, and the blade moves to contact the LCD covered with FPC placed on the carrier platform, and then the blade and the carrier platform are relatively displaced in the lateral direction. Since the heating temperature of the blade can be increased, the viscosity of the high-temperature adhesive used to bond the FPC and the LCD panel is reduced, which is conducive to better separation of the FPC from the LCD carrier board, reducing the difficulty of peeling and reducing the breakage of the LCD panel. The heating method is no longer to heat the LCD panel, but to heat the blade. The blade has a higher temperature and less heat. Therefore, when the blade contacts the PFC, the main heat is transferred to the high-temperature adhesive, and the remaining heat can also be quickly conducted through the LCD carrier board to reduce LCD red and blue spots.

[0031] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] The utility model proposes a heating peeling device 100 to achieve the above purpose, comprising a carrier 1 and a peeling mechanism 2. The carrier 1 is used to carry an LCD carrier board with FPC adhered thereon; the peeling mechanism 2 comprises a blade 22 and a heating part 21 capable of heating the blade 22, and the blade 22 is located above the carrier 1; wherein the blade 22 and the carrier 1 have a relative up-and-down motion stroke and a relative lateral motion stroke, in which the blade 22 can contact the LCD carrier board with FPC adhered thereon on the carrier 1, and in the lateral motion stroke, the blade 22 can peel off the FPC adhered thereon on the LCD carrier board on the carrier 1.

[0036] The technical solution of the utility model places the LCD carrier board covered with FPC on the carrier platform 1, uses the heating part 21 to provide heat to the blade 22, so that the temperature of the blade 22 rises, and the blade 22 moves to contact the LCD covered with FPC placed on the carrier platform 1, and then the blade 22 and the carrier platform 1 are relatively displaced in the lateral direction. Since the heating temperature of the blade 22 can be increased, the high-temperature adhesiveness used to bond the FPC and the LCD panel is reduced, which is conducive to better separation of the FPC from the LCD carrier board, reducing the difficulty of peeling and reducing the breakage of the LCD panel. The heating method is no longer to heat the LCD panel, but to heat the blade 22. The blade 22 has a higher temperature and less heat. Therefore, when the blade 22 contacts with the PFC, the main heat is transferred to the high-temperature adhesive, and the remaining heat can also be quickly conducted through the LCD carrier board to reduce LCD red and blue spots.

[0037] In one embodiment, the blade 22 can be movably arranged up and down, so that the blade 22 and the carrier 1 have a relative up and down movable stroke;

[0038] The heating and peeling device 100 further includes a blade 22 driving device for driving the blade 22 to move up and down.

[0039] It is understandable that, since the mass and volume of the blade 22 are smaller than the LCD carrier, the active setting of the driving blade 22 is conducive to improving the accuracy and flexibility of the control of the corresponding blade 22. In addition, by adjusting the upper and lower positions of the blade 22, it is not only easy to install or remove the LCD carrier from the carrier 1, but also can be adjusted according to the thickness of the LCD carrier with different FPCs, thereby improving the versatility of the peeling and heating device. The blade 22 driving device can be an electric driving device (generating linear motion through a motor), a pneumatic driving device (using compressed air as a power source to drive the piston to move linearly), a hydraulic driving device (using liquid pressure as a power source to drive the piston to move linearly) and a mechanical driving device (lever and pulley: linear motion is achieved through a lever and pulley system. Screw mechanism: using a screw pair (such as a lead screw and a nut) to convert rotational motion into linear motion. Crank and rocker: reciprocating linear motion is achieved through a crank and rocker mechanism.) It is sufficient to realize the linear drive of the blade 22, and no unnecessary details are given here.

[0040] In one embodiment, the heating portion 21 includes a heating block 211 , and the blade 22 is mounted on the lower end of the heating block 211 .

[0041] It is understandable that the heating block 211 is used to generate heat and transfer it to the blade 22. The source of heat can be electric heating or other devices that can reach the temperature of the heating block 211. The blade 22 can not only receive the heat provided by the heating block 211 in a timely manner, but also improve the rapid response of the blade 22 to the temperature, thereby making the stripping operation more accurate. In addition, during the stripping process, the blade 22 needs to withstand a certain amount of pressure and friction, and by connecting with the heating block 211, it can be ensured that the blade 22 is not easy to loosen or shift during operation. The connection between the blade 22 and the heating block 211 is conducive to maintaining the stability of the entire heating stripping device 100, thereby improving the working reliability of the entire device.

[0042] It should be noted here that the mass and volume of the mounting block are much larger than the mass and volume of the blade 22, in order to keep the temperature of the blade 22 within a certain range during the stripping process to ensure that it can operate stably during the stripping process.

[0043] In one embodiment, the heating block 211 is provided with a mounting hole 212 , and the mounting hole 212 is used for mounting a heating element so as to heat the blade 22 through the heating block 211 .

[0044] It can be understood that the mounting hole 212 is located inside the heating block 211, which can not only connect the heating element to the heating block 211, but also increase the contact area between the heating element and the heating block 211, increase the heating speed of the heating element to the heating block 211, and reduce the contact with the external environment, thereby improving the heating efficiency.

[0045] In one embodiment, a mounting groove 213 is disposed at the lower end of the mounting block, and the upper end of the blade 22 is mounted to the mounting groove 213 .

[0046] It can be understood that by installing the upper end of the blade 22 into the mounting groove 213, it can be ensured that the connection between the blade 22 and the heating block 211 is firm and reliable, not easy to loosen or shift, and the position accuracy of the blade 22 during operation is maintained, thereby improving the accuracy of the stripping operation.

[0047] In addition, the installation of the mounting groove 213 makes it easier to install and remove the heating block 211 and the blade 22, and the design of the mounting hole 212 makes it easier to install and remove the heating element and the heating block 211. When it is necessary to replace the heating element or the blade 22, it is only necessary to simply remove or install the corresponding components, without the need for complex disassembly and reorganization of the entire heating unit 21. Specifically, in this embodiment, a row of longitudinal through holes is provided at the position of the heating block 211 corresponding to the mounting groove 213, and the through holes are connected to the mounting groove 213, and bolts can be installed in the through holes to press the blade 22 to connect with the heating block 211.

[0048] In one embodiment, an arc-shaped groove 214 is formed on one side of the heating block 211 at a position adjacent to the blade 22 .

[0049] An arc-shaped groove 214 is formed on one side of the heating block 211 at a position adjacent to the blade 22 .

[0050] It is understandable that the arc groove 214 can guide and position the FPC to be stripped. When the FPC is pushed toward the blade 22 for stripping, the arc groove 214 can serve as a natural guide path, allowing the FPC to reach the blade 22 more smoothly and accurately, thereby improving the efficiency and accuracy of stripping.

[0051] It should be noted here that since the reinforcing plate on the FPC will push against the heating block 211 and make it unable to move, the arc groove 214 can make the reinforcing plate slightly deform along the groove surface, which can avoid the problem of the reinforcing plate getting stuck on the heating block 211. In addition, the blade 22 is lengthened (greater than the width of the reinforcing plate) to increase the temperature of the heating block 211, so as to separate the reinforcing plate from the iron frame.

[0052] In one embodiment, the blade 22 is provided with an anti-stick coating.

[0053] It is understandable that the anti-stick coating is mainly used to solve the adhesion problem that the blade 22 may encounter in actual operation. The anti-stick coating is a surface coating with special properties, which can effectively reduce the adhesion between the blade 22 and the peeling material, making the peeling process smoother and reducing operational obstacles and blade 22 wear caused by adhesion. This coating usually has excellent anti-adhesion properties, can keep the blade 22 clean and sharp for a long time, and improve the efficiency and reliability of the entire peeling process.

[0054] Specifically, in this embodiment, the anti-stick coating is made of Teflon and is plated on the edge of the blade 22. The Teflon coating also has good heat shock resistance and wear resistance, so that the blade 22 can remain stable when working at high temperatures.

[0055] In one embodiment, the blade 22 is arranged at an angle.

[0056] It is understandable that by making the blade 22 present a certain tilt angle, the contact mode and cutting angle between the blade 22 and the PFC to be peeled off can be changed, and the blade 22 can better cut into the adhesion between the PFC and the LCD carrier, reducing the cutting resistance and improving the peeling speed and effect.

[0057] In one embodiment, the carrier 1 is arranged to be movable in the lateral direction, so that the blade 22 and the carrier 1 have a relative lateral movable stroke;

[0058] The heating and peeling device 100 further includes a stage driving device 11 , which is drivingly connected to the carrying platform 1 to drive the carrying platform 1 to move horizontally.

[0059] In this way, the LCD carrier board with FPC attached thereto can be driven by the carrier 1 to move toward the blade 22 to achieve the peeling action, and the adjustment can be made according to the size and shape of the LCD carrier board, thereby improving the applicable range of the carrier 1. The carrier driving device 11 can accurately control the moving speed and position of the carrier 1. Through the action of the carrier driving device 11, the carrier 1 can move smoothly in the horizontal direction, ensuring the accuracy and stability of the peeling operation.

[0060] In one embodiment, a limiting portion 12 is disposed on the carrier 1, and the limiting portion 12 is used to limit the position of the LCD carrier.

[0061] It is understandable that the accuracy and stability of the peeling operation are ensured by limiting the position of the LCD carrier by the limiting portion 12. The limiting portion 12 can be designed in various forms, such as a raised stopper, a groove, or other structures capable of fixing the LCD carrier. By adjusting the shape and size of the limiting portion 12, it can be ensured that the LCD carrier is firmly fixed on the carrier 1 to prevent movement or slipping during the peeling process.

[0062] In one embodiment, the limiting portion 12 includes a vacuum adsorption hole 121 disposed on the supporting platform 1 .

[0063] It can be understood that by generating negative pressure in the vacuum adsorption holes 121, a tight adsorption force is formed between the LCD carrier and the carrier platform 1. When the LCD carrier is placed on the carrier platform 1, the vacuum adsorption holes 121 will quickly adsorb the surface of the LCD carrier and firmly fix it on the carrier platform 1. This adsorption method is not only stable and reliable, but also can adapt to LCD carriers of different sizes and shapes.

[0064] Specifically, in this embodiment, a vacuum cavity 14 is provided inside the carrier 1, whose air inlet is connected to the vacuum adsorption hole 121, and whose air outlet is connected to the external negative pressure device, and the negative pressure generated by the negative pressure device is transmitted to the vacuum adsorption hole 121 via the vacuum cavity 14. In this way, the vacuum adsorption hole 121 and the negative pressure device can be smoothly connected, so that the negative pressure can be efficiently transmitted to the vacuum adsorption hole 121.

[0065] In one embodiment, at least one supporting portion 13 is protruded from the supporting platform 1 .

[0066] It should be noted that when the LCD carrier is adsorbed by the vacuum adsorption holes 121, the adsorbed portion will be deformed to a certain extent, causing the blade 22 to be unable to contact the LCD carrier with the FPC adhered thereto, and the FPC cannot be peeled off. To this end, in this embodiment, the LCD carrier is supported by the support portion 13 so that each portion can be supported uniformly and stably. At the same time, the height and shape of the support portion 13 can also be adjusted to accommodate LCD carriers of different thicknesses.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
