The first adhesive application mechanism includes a first adhesive application component and an adhesive application box. At least a portion of the first adhesive application component is located inside the adhesive application box, which contains an adhesive application medium.

Description

Technical Field

[0001] This invention relates to the field of adhesive application technology, and more particularly to an adhesive application mechanism. Background Technology

[0002] LED backlight screens are displays that use LEDs as backlight sources. Their production process typically includes: (1) Cleaning: Ultrasonic cleaning of PCBs or LED brackets and drying; (2) Mounting: After applying silver paste to the bottom electrode of the LED chip, it is expanded, and the expanded chip is placed on the crystal-piercing platform. The chip is then mounted on the corresponding pads of the PCB or LED bracket using a crystal-piercing pen, and then sintered to solidify the silver paste; (3) Wire bonding: The electrode is connected to the LED chip using an aluminum wire or gold wire bonding machine to serve as a current injection lead; (4) Encapsulation: The LED chip and bonding wire are protected with epoxy by dispensing; (5) Welding; (6) Film cutting: Various extended films, reflective films, etc. required for the backlight are die-cut using a punch press; (7) Assembly: The various materials of the backlight are installed in the correct positions; (8) Testing: The photoelectric parameters and light uniformity of the backlight are checked; (9) Packaging: The finished product is packaged and stored.

[0003] In the packaging process, to improve production efficiency, a dedicated dispensing mechanism is usually used for dispensing. This mechanism typically uses nozzles to directly dispense the adhesive. After dispensing, due to the fluidity of the adhesive, some residue often remains at the nozzle. If a second dispensing is performed directly on this residue, it will affect the overall product yield. Therefore, after the first dispensing or before the second dispensing, the nozzle orifice of the dispensing mechanism needs to be wiped clean. In existing technologies, to match the efficiency of the dispensing mechanism, a suitable wiping mechanism is usually used for automated wiping. However, existing wiping mechanisms typically use a lint-free cloth, which moves along the plane of the nozzle orifice. Since the nozzle orifice is not a perfectly flat surface but has depressions or protrusions, directly using a lint-free cloth for wiping can result in insufficient cleaning, affecting the second dispensing. Summary of the Invention

[0004] The purpose of this invention is to provide an adhesive application mechanism, wherein the contact surface with the object to be adhesiveed is arc-shaped and can perform two applications of adhesive, thereby reducing the phenomenon of incomplete adhesive application and improving the adhesive application effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This invention provides an adhesive application mechanism, comprising:

[0007] The first adhesive wiping mechanism includes a first adhesive wiping component and an adhesive wiping box. At least a portion of the first adhesive wiping component is located inside the adhesive wiping box. The adhesive wiping box contains an adhesive wiping medium. The adhesive wiping medium adheres to the outer surface of the first adhesive wiping component as it rotates. The first adhesive wiping component can perform one adhesive wiping operation on the object to be wiping by rotating itself.

[0008] The second adhesive wiping mechanism is located on one side of the first adhesive wiping mechanism. The second adhesive wiping mechanism includes a second adhesive wiping component, which can move relative to the object to be wiped to perform a second adhesive wiping on the object.

[0009] Preferably, the first adhesive application mechanism further includes a switching structure, which is disposed at at least one end of the first adhesive application component and is used for replacing the first adhesive application component.

[0010] Preferably, the switching structure includes a connecting portion disposed at the end of the first adhesive wiping member and a limiting portion located at the end of the first adhesive wiping member, wherein the limiting portion limits the first adhesive wiping member by cooperating with the connecting portion.

[0011] Preferably, the connecting part includes a bearing disposed at the end of the first wiping member, and the limiting part limits the first wiping member by cooperating with the bearing.

[0012] Preferably, the limiting part is provided with a limiting groove and includes a limiting member, the limiting member is disposed on one side of the limiting groove, the limiting groove is used to accommodate the connecting part, and the limiting member is used to restrict the connecting part from moving out of the limiting groove.

[0013] Preferably, the first adhesive application mechanism further includes a rotary drive component, which includes a power component and a transmission component. The power component is connected to the transmission component. The connecting portion includes a rotating shaft with a rotating surface. The transmission component is provided with a transmission groove for accommodating the rotating shaft, and the transmission groove has a transmission surface adapted to the rotating surface.

[0014] Preferably, the second adhesive wiping mechanism further includes an adhesive wiping track and a tensioning mechanism. The second adhesive wiping component can move along the adhesive wiping track, and the tensioning mechanism is located on the adhesive wiping track and is used to tension the second adhesive wiping component.

[0015] Preferably, a lifting mechanism is also included, which is disposed at the bottom of the first and / or second adhesive application mechanism for lifting the first and / or second adhesive application mechanism so that the first and / or second adhesive application mechanism approaches the object to be adhesive applied.

[0016] Preferably, a dustproof mechanism is also included for covering the first adhesive application mechanism and / or the second adhesive application mechanism; the dustproof mechanism includes a dustproof component and a dustproof drive component, the dustproof drive component being configured to switch the dustproof component between a first position exposing the first adhesive application mechanism and the second adhesive application mechanism and a second position covering the first adhesive application mechanism and the second adhesive application mechanism.

[0017] Preferably, the dustproof mechanism further includes a dustproof support located at the bottom of the dustproof component. When the dustproof component is in the second position, the dustproof support is used to support the dustproof component.

[0018] The beneficial effects of this invention are:

[0019] By rotating the first wiping component, the object to be wiped is wiped once after the wiping medium is applied. The contact surface between the rotating first wiping component and the object to be wiped is usually arc-shaped, and the wiping medium plays a moistening role, so that after the first wiping, no glue residue or only a part of the glue residue remains. Then, the relatively dry second wiping component performs a second wiping, which reduces the phenomenon of incomplete wiping and improves the wiping effect. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0036] Reference Figure 1-2This embodiment discloses an adhesive application mechanism, including: a first adhesive application mechanism 1 and a second adhesive application mechanism 2. The first adhesive application mechanism 1 includes a first adhesive application component 101 and an adhesive application box 102. At least a portion of the first adhesive application component 101 is located inside the adhesive application box 102. The adhesive application box 102 contains an adhesive application medium (not shown in the figure). The adhesive application medium adheres to the outer surface of the first adhesive application component 101 as the first adhesive application component 101 rotates. The first adhesive application component 101 can perform a first adhesive application on the object to be applied (not shown in the figure) by its own rotation. The second adhesive application mechanism 2 is located on one side of the first adhesive application mechanism 1. The second adhesive application mechanism 2 includes a second adhesive application component 201. The second adhesive application component 201 can move relative to the object to be applied to perform a second adhesive application on the object. In this embodiment, the adhesive application box 102 is designed to store adhesive application medium, so its opening is typically upward-facing. Therefore, the first adhesive application component 101 is usually located above the adhesive application box 102. Since the adhesive application medium needs to adhere to the outer surface of the first adhesive application component 101 when it rotates, it is understood that when the first adhesive application component 101 is stationary, its bottom is usually in contact with the adhesive application medium. That is, the highest level of the adhesive application medium in the adhesive application box 102 is higher than the lowest level of the first adhesive application component 101. Since the adhesive application medium is usually a consumable, this can be achieved by adjusting the height difference between the first adhesive application component 101 and the bottom of the adhesive application box 102, or by replenishing the adhesive application medium. In this embodiment, the adhesive application medium can typically be a wetting medium such as alcohol that can assist in adhesive application. In this embodiment, the first adhesive application component 101 can typically be a brush. The second adhesive application mechanism 2 and the first adhesive application mechanism 1 may or may not be connected. In this embodiment, considering the compactness of the entire adhesive application mechanism, the second adhesive application mechanism 2 is disposed on the first adhesive application mechanism 1, or the first adhesive application mechanism 1 is disposed on the second adhesive application mechanism 2; that is, the two preferably have a certain connection. In this embodiment, the second adhesive application component 201 can typically be a lint-free cloth. In this embodiment, by rotating the first adhesive application component 101, after the adhesive application medium is applied, the object to be adhesiveped (in this embodiment, it is usually a nozzle) is applied once. The contact surface between the rotating first adhesive application component 101 and the object to be adhesiveped is usually arc-shaped, and the adhesive application medium plays a moistening role, so that after the first application, no adhesive residue or only a portion of adhesive residue remains. The relatively dry second adhesive application component 201 then performs a second application, reducing the phenomenon of incomplete adhesive application and improving the adhesive application effect.

[0037] Specifically, refer to Figure 3-7In this embodiment, the first adhesive application mechanism 1 further includes a switching structure 103. The switching structure 103 is disposed at at least one end of the first adhesive application component 101 and is used for replacing the first adhesive application component 101. It can be seen that the adhesive application mechanisms in the prior art are usually used for single or small numbers of objects to be adhesive applied. When establishing a connection relationship with the adhesive application component (such as a lint-free cloth), a coupling or other structure is usually used. When it is necessary to replace the adhesive application component (such as a lint-free cloth) or other structure, disassembly is usually cumbersome and the replacement efficiency is low. Therefore, in this embodiment, by setting the switching structure 103, the quick replacement function of the first adhesive application component 101 can be realized. More specifically, the switching structure 103 includes a connecting part 1031 disposed at the end of the first adhesive application component 101 and a limiting part 1032 located at the end of the first adhesive application component 101. The limiting part 1032 limits the first adhesive application component 101 by cooperating with the connecting part 1031. It is understood that the connecting part 1031 is connected to the first adhesive-wiping component 101, and the limiting part 1032 can be disposed at the end position of the first adhesive-wiping component 101 through a support structure. Furthermore, both the first adhesive-wiping mechanism 1 and the second adhesive-wiping mechanism 2 can be disposed in this support structure. For ease of representation, in this embodiment, this support structure is defined as adhesive-wiping support 3. It should be noted that the connecting part 1031 and the first adhesive-wiping component 101 are usually an integral unit, thereby facilitating replacement. In this embodiment, it is preferable that both ends of the first adhesive-wiping component 101 are provided with switching structures 103.

[0038] Specifically, refer to Figure 5-7In this embodiment, the connecting portion 1031 includes a bearing 10311 disposed at the end of the first adhesive wiping member 101. It can be understood that the connecting portion 1031 necessarily has an extension shaft extending outward along the end of the first adhesive wiping member 101 to facilitate the placement of the bearing 10311. The limiting portion 1032 is provided with a limiting groove 10321 and includes a limiting member 10322. The limiting member 10322 is disposed on one side of the limiting groove 10321. The limiting groove 10321 is used to accommodate the connecting portion 1031, and the limiting member 10322 is used to restrict the connecting portion 1031 from moving out of the limiting groove 10321. More specifically, in order to cooperate with the connecting part 1031, the limiting groove 10321 is usually arc-shaped, and its cross-section is usually semi-circular or U-shaped. Preferably, in order to ensure that the limiting groove 10321 has sufficient accommodating space, the limiting groove 10321 is set as U-shaped. For ease of replacement, the opening of the limiting groove 10321 is usually facing upward. It can be understood that the limiting member 10322 is used to close the opening of the limiting groove 10321. In this embodiment, one end of the limiting member 10322 is located on one side of the limiting groove 10321 and is fixed and rotated by a rotating shaft structure. The other end of the limiting member 10322 is detachably fixed to the opposite side of the limiting groove 10321 by a screw or other structure. That is, the limiting member 10322 opens and closes the limiting groove 10321 by a rotating shaft and screw. The other end of the limiting member 10322 can also be detachably connected by a pin or other structure. In order to match the connecting part 1031, the side of the limiting member 10322 facing the connecting part 1031 can also be provided with a certain arc shape to prevent the bearing 10311 from being squeezed.

[0039] Specifically, in this embodiment, the first adhesive application mechanism 1 further includes a rotary drive 104, which includes a power component 1041 and a transmission component 1042. The power component 1041 is connected to the transmission component 1042. The connecting part 1031 includes a rotating shaft 10312, which has a rotating surface 10313. The transmission component 1042 is provided with a transmission groove 1043 for accommodating the rotating shaft 10312, and the transmission groove 1043 has a transmission surface 1044 adapted to the rotating surface 10313. More specifically, in this embodiment, the power component 1041 can be a motor. Since the motor cannot directly connect to the end of the first adhesive-applying component 101, in this embodiment, kinetic energy is transferred through a transmission component 1042. The transmission component 1042 includes a first transmission gear and a second transmission gear. The first transmission gear is connected to the power component 1041, receives the kinetic energy from the power component 1041, and transmits it to the second transmission gear via a transmission belt. The transmission groove 1043 is located on the transmission shaft of the second transmission gear. It can be understood that when the power component 1041 operates, the transmission of the first and second transmission gears causes the transmission shaft of the second transmission gear to rotate. The transmission groove 1043 on the transmission shaft rotates synchronously, and the rotating shaft 10312 within the transmission groove 1043 rotates synchronously, ultimately driving the first adhesive-applying component 101 to rotate. It should be noted that, unlike the shaft of the connecting part 1031 for setting the bearing 10311, the rotating shaft 10312 in this embodiment continues to extend outward along the shaft to protrude independently from the bearing 10311, so that it can be set in the transmission groove 1043. Therefore, the rotating shaft 10312 can also be integrally formed with the shaft, or it can be just connected. The size of the shaft can also be slightly larger than the rotating shaft 10312 to distinguish the two shafts. It can be understood that, in this embodiment, transmission is achieved by setting the rotating shaft 10312 within the transmission groove 1043. Since both the rotating shaft 10312 and the transmission shaft 10312 typically have circular cross-sections, kinetic energy loss is likely during transmission. If the diameters of the two shafts differ significantly, transmission may fail. Therefore, in this embodiment, transmission efficiency is improved by providing a rotating surface 10313 on the rotating shaft 10312 and a transmission surface 1044 within the transmission groove 1043 for mutual cooperation. The rotating surface 10313 and the transmission surface 1044 can be any surface other than a circular arc; preferably, they can be planes for ease of machining. In this embodiment, the rotating drive component 104 can also be mounted on the adhesive-wiping support 3 to maintain the compactness of the entire mechanism.

[0040] Specifically, refer to Figure 8-9In this embodiment, the second adhesive application mechanism 2 further includes an adhesive application track 202 and a tensioning mechanism 203. The second adhesive application component 201 can move along the adhesive application track 202, and the tensioning mechanism 203 is located on the adhesive application track 202 and is used to tension the second adhesive application component 201. It can be understood that for production operations with large output, there are usually multiple objects to be adhesive applied, arranged in a certain regular pattern. Therefore, in this embodiment, in order to match multiple objects to be adhesive applied, an adhesive application track 202 is set so that the second adhesive application component 201 can simultaneously apply adhesive to multiple objects. It can be understood that the adhesive application track 202 is usually set according to the arrangement pattern of the objects to be adhesive applied to save space and reduce the overall size of the mechanism. More specifically, in this embodiment, the second adhesive-wiping component 201 moves using kinetic energy provided by a moving drive component. This moving drive component includes a storage wheel 204 and a receiving wheel 205. The storage wheel 204 stores the cleanroom cloth. When the cleanroom cloth moves and passes through the adhesive-wiping track 202, the receiving wheel 205 receives the cleanroom cloth after it has been wiped. It can be seen that since the storage wheel 204 needs to release the cleanroom cloth and the receiving wheel 205 needs to receive the cleanroom cloth after it has been wiped, a certain amount of kinetic energy is required. Therefore, in this embodiment, motors can be connected to the shafts of both the storage wheel 204 and the receiving wheel 205. These motors can also be mounted on the adhesive-wiping support 3 to reduce the size of the structure. If two motors are used, it is difficult to ensure that the rotation speed is consistent, which may lead to tearing of the cleanroom cloth. Therefore, in this embodiment, preferably, a motor is only mounted on the receiving wheel 205 to ensure that there is kinetic energy while avoiding damage to the cleanroom cloth, and at the same time reducing the size and cost of the entire mechanism. It is known that when there are multiple objects to be rubbed with adhesive, the adhesive rubbing track 202 is usually quite long. Therefore, when the receiving wheel 205 is working to receive the cleanroom cloth, the cleanroom cloth is also quite long, which may cause it to be loose and affect the second rubbing. Therefore, in this embodiment, the cleanroom cloth is tensioned by the tensioning mechanism 203 to keep it taut. It is also preferable to set the tensioning mechanism 203 in the middle of the adhesive rubbing track 202, as the tensioning effect is better than in other positions.More specifically, the tensioning mechanism 203 includes a first tensioning shaft 2031, a second tensioning shaft 2032, and a third tensioning shaft 2033. The first and second tensioning shafts 2031 and 2032 are at the same horizontal height and have a predetermined distance between them. The third tensioning shaft 2033 is located vertically below the first and second tensioning shafts 2031 and 2032, and horizontally at the middle of the first and second tensioning shafts 2031 and 2032. After the lint-free cloth detaches from the adhesive wiping track 202, it passes over the first tensioning shaft 2031 and wraps around the third tensioning shaft 2033. Below 3, it then winds around to the top of the second tensioning shaft 2032 and returns to the adhesive wiping track 202 to achieve tensioning. The top height of the first tensioning shaft 2031 and the second tensioning shaft 2032 is slightly higher than the height of the cleanroom cloth on the moving plane of the adhesive wiping track 202. In order to provide a certain constraint on the cleanroom cloth, a pressure plate 2034 can be provided on the side of the first tensioning shaft 2031 facing the adhesive wiping track 202. The height of the pressure plate 2034 can be slightly greater than the adhesive wiping track 202 and slightly lower than the top height of the first tensioning shaft 2031. The second tensioning shaft 2032 can also be provided with the corresponding pressure plate 2034.

[0041] Specifically, this embodiment also includes a lifting mechanism 4, which is disposed at the bottom of the first adhesive-applying mechanism 1 and / or the second adhesive-applying mechanism 2. The lifting mechanism 4 is used to lift the first adhesive-applying mechanism 1 and / or the second adhesive-applying mechanism 2 so that they approach the object to be adhesive-applying. Since the adhesive-applying mechanism typically maintains a predetermined distance from the object to be adhesive-applying when not in operation, this embodiment, for ease of adhesive application, preferably maintains a predetermined distance in the vertical direction. Therefore, in this embodiment, the lifting mechanism 4 is provided to enable the adhesive-applying mechanism to approach the object to be adhesive-applying for adhesive application. More specifically, in this embodiment, the first adhesive wiping mechanism 1 and the second adhesive wiping mechanism 2 are both set on the adhesive wiping support 3, and the lifting mechanism 4 can be set on the adhesive wiping support 3. The adhesive wiping support 3 may include a movable part 301 and a fixed part 302, wherein the movable part 301 is set on the fixed part 302 and can move relative to the fixed part 302. The first adhesive wiping mechanism 1 and the second adhesive wiping mechanism 2 are both set on the movable part 301, and the lifting mechanism 4 is set at the bottom of the movable part 301 to achieve the lifting effect. Furthermore, since the first adhesive application mechanism 1 typically performs one-time adhesive application and the second adhesive application mechanism 2 typically performs two-time adhesive application, interference may occur if they are simultaneously lifted to the same height. Therefore, in this embodiment, the lifting mechanism 4 includes a first lifting component 401 and a second lifting component 402. The first lifting component 401 is located at the bottom of the movable part 301 and is used to lift the movable part 301, allowing the movable part 301 to move relative to the fixed part 302, thereby lifting the first adhesive application mechanism 1 and the second adhesive application mechanism 2 located on the movable part 301. The second lifting component 402 is located at the bottom of the second adhesive application mechanism 2 and is mounted on the movable part 301 via the second lifting component 402. The second lifting component 402 is used to perform a secondary lifting of the second adhesive application mechanism 2. In the initial position, the height of the second adhesive application mechanism 2 is slightly lower than that of the first adhesive application mechanism 1. Therefore, after the first lifting component 401 works, only the first adhesive application mechanism 1 reaches the working height to work. After the second lifting component 402 works, the second adhesive application mechanism 2 reaches the working height. In this embodiment, both the first lifting component 401 and the second lifting component 402 can be implemented by cylinders.

[0042] Specifically, refer to Figure 10In this embodiment, a dustproof mechanism 5 is further included, used to cover the first adhesive wiping mechanism 1 and / or the second adhesive wiping mechanism 2. The dustproof mechanism 5 includes a dustproof component 501 and a dustproof driving component 502. The dustproof driving component 502 is configured to switch the dustproof component 501 between a first position exposing the first adhesive wiping mechanism 1 and the second adhesive wiping mechanism 2 and a second position covering the first adhesive wiping mechanism 1 and the second adhesive wiping mechanism 2. When the adhesive wiping mechanism is not in operation, the working environment usually cannot maintain absolute cleanliness, and the lint-free cloth is easily affected by dust and other factors, affecting subsequent adhesive wiping actions. Therefore, in this embodiment, by setting the dustproof mechanism 5, the lint-free cloth can be covered to a certain extent when the adhesive wiping mechanism is not in operation, i.e., it has a protective function. In this embodiment, in order to ensure the compactness of the structure and reduce the volume of the entire mechanism, the dustproof mechanism 5 is located on the other side of the first adhesive wiping mechanism 1, and the dustproof mechanism 5 can simultaneously protect the first adhesive wiping mechanism 1 and the second adhesive wiping mechanism 2 from dust, that is, it simultaneously protects the adhesive wiping medium and the second adhesive wiping component 201 (i.e., the dust-free cloth in this embodiment) in the adhesive wiping box 102.

[0043] Specifically, in this embodiment, the dustproof mechanism 5 further includes a dustproof support 503, which is located at the bottom of the dustproof component 501. When the dustproof component 501 is in the second position, the dustproof support (503) supports the dustproof component (501). The dustproof component 501 is made of a soft material, so when it is not in operation, one part is horizontal and the other part can be vertical, thus saving space occupied by the entire mechanism and reducing its volume. In this embodiment, the dustproof drive component 502 can be a cylinder. One end of the dustproof component 501 is connected to the cylinder's push rod. When the push rod retracts, it moves one end of the dustproof component 501 toward the cleanroom cloth, at which time the dustproof support 503 supports the other end of the dustproof component 501. Both the dustproof drive component 502 and the dustproof support 503 can be set at a predetermined height by an external frame. In this embodiment, the external frame will not be specifically described. Furthermore, dustproof drive components 502 are provided on both sides of the dustproof component 501 to prevent the dustproof component 501 from tilting during movement.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
