Description

Technical Field

[0001] This utility model relates to the field of display device manufacturing technology, and in particular to a display panel film debubbler. Background Technology

[0002] During the manufacturing process of display panels, polarizing films, protective films, and other layers need to be applied to the panels to improve visual effects and provide waterproofing. Current technology primarily utilizes laminating machines to apply these films to the display panels. (Refer to...) Figure 1 As shown, the laminating machine includes two spaced-apart rollers 3'. The display panel 1' and the laminating assembly 2' are stacked together and passed between the two rollers 3', which press the display panel 1' and the laminating assembly 2' together. The laminating assembly 2' includes a carrier and a film layer 21' adhered to the carrier. After the display panel 1' and the laminating assembly 2' are laminated, the carrier in the laminating assembly 2' is peeled off, thus attaching the film layer 21' to the display panel 1'. Due to the lamination shape of the film layer 21' itself, the vibration of the rollers 3', and the levelness of the laminating assembly 2', air bubbles 22' may form on the film layer 21'. These air bubbles 22' affect the overall quality of the display panel 1'. For example, when the film layer 21' is a polarizing film, the presence of air bubbles 22' can affect the local light emission direction of the display panel 1', impacting the visual effect. When the film layer 21' is a protective film, the presence of air bubbles 22' can affect the overall appearance of the display panel 1'.

[0003] The existing method for handling air bubbles 22' on the film layer 21' is to peel off the film layer 21' containing air bubbles and reapply the film. This method results in waste of the film layer 21' and a longer rework time. Alternatively, the operator can use a needle to puncture the air bubbles 22', then squeeze out the air and smooth the rework area. However, during the needle puncture process, the film layer 21' easily adheres to the surface of the display panel 1' along with the needle tip, making it difficult to puncture. Furthermore, the operator's forceful operation can damage other structures on the display panel 1' with the needle tip. Utility Model Content

While ensuring that the needle can successfully pierce the film, it can also avoid damage to other structures on the display panel. It features high reliability and cost savings in manufacturing.

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

[0006] A display panel film debubbler is provided, comprising:

[0007] A housing having a receiving cavity inside, and an opening communicating with the receiving cavity at one end of the housing facing the display panel;

[0008] A bubble-piercing assembly, the bubble-piercing assembly including a needle disposed within the receiving cavity, the tip of the needle facing the opening, the tip of the needle being used to pierce bubbles on the display panel;

[0009] The extrusion assembly includes two extrusion blocks spaced apart within the receiving cavity. One end of each extrusion block passes through the opening and abuts against the display panel. One of the extrusion blocks is movable so that the two extrusion blocks can move closer to or further apart from each other. The tip of the needle is located between the two extrusion blocks. At least one of the extrusion blocks has a notch for avoiding the needle.

[0010] A flattening assembly, comprising rollers disposed on the outer wall of the housing, the rollers being used to roll the corresponding area of ​​the bubble.

[0011] As a preferred embodiment of the display panel film debubbling device, the two extrusion blocks are a first extrusion block and a second extrusion block. The first extrusion block is fixedly connected to the housing, and the second extrusion block is slidably connected to the housing. A push rod is provided on the second extrusion block, and one end of the push rod away from the second extrusion block extends to the outside of the housing. The push rod drives the second extrusion block to move closer to or away from the first extrusion block.

[0012] As a preferred embodiment of the display panel film debubbling device, the second extrusion block is elastically connected to the housing.

[0013] As a preferred embodiment of the display panel film debubbling device, both extrusion blocks are provided with notches, and the two notches can be interlocked to form a closed space. The width of the notches gradually decreases from the middle to both ends along a first direction, which is perpendicular to the moving direction of the extrusion blocks.

[0014] As a preferred embodiment of the display panel film debubbling device, the opposing sides of the two extrusion blocks are configured as inclined or curved surfaces, and the width of the extrusion blocks gradually decreases from the end closer to the display panel to the end farther away from the display panel.

[0015] As a preferred embodiment of the display panel film debubbling device, the housing is provided with an observation window, which faces the area between the two inclined surfaces or the two curved surfaces.

[0016] As a preferred embodiment of the display panel film debubbling device, the bubble-piercing assembly further includes an air pump, the piercing needle is a hollow needle, one end of the air pump is connected to the piercing needle, and the other end is connected to the outside of the housing through an air tube.

[0017] As a preferred embodiment of the display panel film debubbling device, the bubble-piercing assembly further includes a light plate for emitting multiple light beams toward the display panel, with the tip of the needle located between the multiple light beams.

[0018] As a preferred embodiment of the display panel film debubbling device, the bubble-piercing assembly further includes a clamping part connected to the air pump. The clamping part includes two interlocking semicircular plates, and the blunt end of the needle is inserted between the two semicircular plates.

[0020] The advantages of this utility model compared to the prior art are:

[0021] This utility model discloses a display panel film debubbling device. It employs two pressing blocks that can approach each other, with a needle positioned between them. The two pressing blocks compress the air bubbles, reducing their coverage area on the display panel. During compression, some film layers adhere smoothly to the panel under the pressure of the blocks. As the two pressing blocks approach each other, the air bubbles gradually concentrate within the notches of the blocks. This concentration causes the corresponding film layer to bulge, making it easier for the needle to puncture it. As the bubbles concentrate towards the notches, the film layer is punctured, and the air inside the bubbles escapes through the punctured holes. When the two pressing blocks come together, they can no longer compress the remaining bubble area. Finally, a roller is used to roll back and forth, further flattening the entire bubble area to meet the film application quality requirements of the display panel. Compared to existing methods of reapplying film, this method allows the film layer with air bubbles to be reused after bubble removal, avoiding material waste and reducing manufacturing costs. Furthermore, compared to manual needle puncture, using a needle to puncture the bubbles during compression increases the success rate, avoids multiple puncture operations on the film layer, and reduces pitting and indentation on the film layer. Simultaneously, because the needle does not move towards the display panel, but rather utilizes the expansion of the film layer during compression to move it towards the needle for puncture, damage to other structures on the display panel is avoided. Therefore, this debubbler features high reliability and helps reduce manufacturing costs. Attached Figure Description

[0033] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 2 to 4 As shown, a debubbler for display panel film application (hereinafter referred to as a debubbler) is provided to eliminate air bubbles generated during the film application process of the display panel 5. After the circuit layer and light-emitting layer of the display panel 5 are fabricated, a polarizing film and / or a protective film are applied to its surface to improve the visual effect of light emission and provide protection. Since the polarizing film or protective film forms a single product after being applied to the display panel 5, the debubbler processes the film-applied display panel 5. Therefore, the display panel 5 described in this embodiment is a processing object that includes the film layer covering the display panel 5. In this embodiment, the air bubbles are essentially air trapped between the display panel 5 and the film layer, and the air bubbles are specifically manifested as localized protrusions in the film layer. Eliminating the air bubbles on the display panel 5 using the debubbler eliminates the air trapped between the display panel 5 and the film layer, allowing the film layer to adhere smoothly to the surface of the display panel 5.

[0036] The debubbler includes a housing 1, a bubble-piercing assembly 2, a bubble-extrusion assembly 3, and a flattening assembly 4. The housing 1 provides overall support and installation space for the bubble-piercing assembly 2, the bubble-extrusion assembly 3, and the flattening assembly 4. The housing 1 is a hollow structure with an internal cavity 10, within which the bubble-piercing assembly 2 and the bubble-extrusion assembly 3 are installed. In operation, the display panel 5 is placed horizontally, and the housing 1 rests on the upper surface of the display panel 5. An opening 16 is provided at the end of the housing 1 facing the display panel 5 (i.e., the bottom surface of the housing 1), and the cavity 10 communicates with the outside of the housing 1 through the opening 16. The bubble-piercing assembly 2 is used to pierce the bubbles on the display panel 5. The bubble-piercing assembly 2 includes a needle 23 disposed within the cavity 10, with one end being a pointed tip and the other a blunt end. The pointed tip of the needle 23 is positioned downwards, i.e., facing the opening 16 of the housing 1. The pointed tip of the needle 23 extends to the opening 16 and is used to pierce the bubbles on the display panel 5. The bubble extrusion assembly 3 is used to extrude bubbles and flatten the film layer corresponding to the bubble area onto the display panel 5. The bubble extrusion assembly 3 includes extrusion blocks 31 spaced apart within the receiving cavity 10. The bottom end of the extrusion block 31 passes through the opening 16 and abuts against the display panel 5, that is, the extrusion block 31 directly presses against the film layer. One of the extrusion blocks 31 is movable so that the two extrusion blocks 31 can move closer or further apart. The tip of the needle 23 is located between the two extrusion blocks 31, and at least one of the extrusion blocks 31 is provided with a notch 33 for avoiding the needle 23. When the two extrusion blocks 31 move closer together, the bubble is squeezed into the area between the two extrusion blocks 31 and punctured by the needle 23. Then the gas inside the bubble is discharged under the squeezing action of the extrusion block 31 to eliminate the bubble. The flattening assembly 4 is disposed on the outer wall of the housing 1 and includes a roller 41 rotatably mounted on the outer wall of the housing 1. After the bubbles are punctured and squeezed, the roller 41 is used to roll back and forth in the corresponding area of ​​the bubbles so that the film layer in that area is flatly attached to the display panel 5.

[0037] Understandably, by setting two pressing blocks 31 that can approach each other, and placing a needle 23 between the two pressing blocks 31, the two pressing blocks 31 can be used to compress the air bubbles. On the one hand, this reduces the area covered by the air bubbles on the display panel 5. During the compression process, part of the film layer is flattened onto the display panel 5 under the compression of the pressing blocks 31. As the two pressing blocks 31 approach each other, the air bubbles are gradually concentrated in the notches 33 of the pressing blocks 31. The concentration of air bubbles causes the corresponding film layer in this area to bulge, which is conducive to the film layer being punctured by the needle 23. As the air bubbles concentrate in the notches 33, the film layer is punctured by the needle 23, and the air inside the air bubbles is discharged through the punctured holes. When the two pressing blocks 31 come together, it is impossible to continue compressing the remaining air bubble area. Finally, the roller 41 is used to roll back and forth to further flatten the entire air bubble area to meet the film application quality requirements of the display panel 5. Compared to existing technologies that involve re-applying the film, this debubbling device allows the film layer containing air bubbles to be reused after the bubbles are removed, avoiding material waste and reducing manufacturing costs. Furthermore, compared to manual needle piercing, using the needle 23 to puncture the bubbles during compression increases the success rate, avoids multiple puncture operations, and reduces pitting and indentations on the film layer. Simultaneously, since the needle 23 does not move towards the display panel 5, but rather utilizes the expansion of the film layer during compression to move it towards the needle 23 for puncture, it avoids damage to other structures on the display panel 5. Therefore, this debubbling device features high reliability and contributes to reduced manufacturing costs.

[0038] Specifically, refer to Figure 3 As shown, the receiving cavity 10 inside the housing 1 is divided into upper and lower chambers by a partition 13. The two chambers are the upper chamber 11 located above and the lower chamber 12 located below. A through hole is provided on the partition 13, through which the upper chamber 11 and the lower chamber 12 communicate. The bubbling assembly 2 is installed in the upper chamber 11, and one end of the bubbling assembly 2 passes through the partition 13 and extends to the opening 16. The extrusion assembly 3 is installed in the lower chamber 12.

[0039] The extrusion assembly 3 also includes a push rod 34 and a spring 35. Two extrusion blocks 31 are designated as a first extrusion block 311 and a second extrusion block 312, respectively. The first extrusion block 311 and the second extrusion block 312 are spaced apart within the lower chamber 12 along the width direction (Y direction in the figure) of the housing 1. The top of the first extrusion block 311 is fixedly connected to a partition 13 in the housing 1, and the second extrusion block 312 is slidably connected to the partition 13 in the housing 1. The push rod 34 is used to push the second extrusion block 312 to slide along the width direction of the housing 1. One end of the push rod 34 is connected to the second extrusion block 312, and the other end of the push rod 34, away from the second extrusion block 312, passes through the side wall of the housing 1 and extends to the outside of the housing 1. The end of the push rod 34 located outside the housing 1 is for operator use; the operator can use the push rod 34 to drive the second extrusion block 312 closer to or further away from the first extrusion block 311. The second extrusion block 312 is elastically connected to the housing 1 by a spring 35, which is sleeved around the periphery of the push rod 34. When it is necessary to squeeze the air bubble, the push rod 34 pushes the second squeezing block 312 toward the first squeezing block 311, and the spring 35 extends. After squeezing is completed, the push force on the push rod 34 is released, and the spring 35 rebounds, so that the second squeezing block 312 returns to its initial position.

[0040] Specifically, refer to Figure 4 and Figure 5 As shown, both extrusion blocks 31 are provided with notches 33, which are used to accommodate bubbles and the tips of needles 23. When the two extrusion blocks 31 abut against each other, the corresponding notches 33 on the two extrusion blocks 31 interlock and form a closed space. Along the first direction (Y direction in the figure), the width of the notch 33 gradually decreases from the middle to both ends of the notch 33. The first direction is perpendicular to the moving direction of the second extrusion block 312. This structure makes the closed space inside the two notches 33 elliptical after interlocking, which is beneficial for the two extrusion blocks 31 to squeeze the bubbles to the maximum extent, so that most of the area on the film layer corresponding to the bubble is smoothed by the extrusion blocks 31 during the movement, promoting the film layer to adhere smoothly to the display panel 5. When the two extrusion blocks 31 abut against each other, the tip of the needle 23 is located in the middle of the closed space between the two notches 33. It should be noted that the width of the notch 33 in this embodiment is C / 2.

[0041] The opposing sides of the two extrusion blocks 31 are configured as inclined surfaces or curved surfaces 32. The width dimension B of the extrusion block 31 gradually decreases from the end closer to the display panel 5 to the end farther away from the display panel 5. It can be understood that in the working state, the extrusion block 31 is located on the top surface of the display panel 5, that is, the width dimension B of the extrusion block 31 gradually decreases from the bottom end to the top end of the display panel 5. When the two extrusion blocks 31 abut against each other, a space is formed between the two inclined surfaces or the two curved surfaces 32, which can be used to adjust the internal air pressure and accommodate some air bubbles.

[0042] Specifically, refer to Figure 2 As shown, an observation window 14 is provided on one or both sides along the length of the housing 1 (reverse direction of X in the figure), and a transparent glass is installed on the observation window 14. The observation window 14 faces the area between the two inclined surfaces or two curved surfaces 32, and the operator can see the bubbles and needles 23 between the two extrusion blocks 31 through the observation window 14, so that the operator can perform bubble piercing and extrusion operations.

[0043] Specifically, refer to Figure 3 and Figure 6 As shown, the puncture assembly 2 includes a base 21, a clamping part 22, a lamp plate 26, and a puncture needle 23. The base 21 is a cylindrical structure and is vertically installed in the upper chamber 11. An end plate 28 is provided at the bottom end of the base 21, and the clamping part 22 is installed on the end plate 28. One end of the clamping part 22 passes through the partition 13 and extends downward into the lower chamber 12. The clamping part 22 includes two interlocking semicircular plates 221, and the blunt end of the puncture needle 23 is inserted between the two semicircular plates 221. A nut 222 is fitted around the periphery of the clamping part 22, and the two semicircular plates 221 are clamped together by the nut 222 to install and fix the puncture needle 23. When the tip of the puncture needle 23 becomes blunt or deformed due to long-term use, the puncture needle 23 can be removed from the clamping part 22 for replacement.

[0044] An air pump 24 and a battery pack are installed inside the base 21, with the air pump 24 electrically connected to the battery pack. The needle 23 is a hollow needle with an internal airflow channel. One end of the air pump 24 is connected to the needle 23 via an air pipe 25, and the other end is connected to the outside of the housing 1 via the same air pipe 25. Alternatively, the air pipe 25 can be directly connected to the blunt end of the needle 23, or it can be connected to one end of the clamping part 22, with the inside of the clamping part 22 connected to the needle 23. By pumping air from the needle 23 through the air pump 24, the air inside the punctured bubble is quickly drawn to the outside of the housing 1 through the needle 23, air pipe 25, and air pump 24. Since the bubble in the notch 33 cannot continue to be squeezed by the squeezing block 31, the air pump 24 is used to extract the air that cannot be squeezed out, ensuring that all the air inside the bubble is expelled.

[0045] A light panel 26 is installed inside the base, and is positioned near the end plate 28 at the bottom of the base 21. Several light bulbs are mounted on the light panel 26; preferably, these bulbs are red light bulbs that emit red light. The end plate 28 has multiple positioning holes 27 so that the light emitted by the light panel 26 can pass through the positioning holes 27 and be projected downwards onto the display panel 5. Correspondingly, a clamping part 22 is installed in the middle of the end plate 28, and the multiple positioning holes 27 are distributed along the circumference of the clamping part 22. During operation, the operator places the debubbler on the display panel 5. The light emitted by the light panel 26 passes through the positioning holes 27 and forms multiple beams, which are projected onto the display panel 5. The tip of the needle 23 is located between the multiple beams. That is, the position of the beam is used to align with the bubble so that the needle 23 is positioned in the center of the bubble. In this embodiment, the light beam emitted by the light panel 26 aligns the bubble on the display panel 5 so that the debubbler is placed in the appropriate position.

[0046] Specifically, refer to Figure 2 and Figure 3 As shown, the flattening assembly 4 includes rollers 41 and ear plates 42. Two ear plates 42 are provided, spaced apart along the length direction (X direction in the diagram) of the housing 1 on the outer wall of the housing 1. The two ends of the rollers 41 are rotatably connected to the two ear plates 42 respectively. An opening 16 is provided on the bottom surface of the housing 1, forming an inclined surface between the bottom surface and one of the sides of the housing 1 in the width direction; the ear plates 42 are mounted on this inclined surface. The rollers 41 are higher than the bottom surface of the housing 1. When the debubbler is placed on the display panel 5 for bubble puncture and extrusion processing, the rollers 41 are spaced apart from the display panel 5. When it is necessary to roll the corresponding area of ​​the bubble, the operator tilts the debubbler and rolls the rollers 41 on the display panel 5 to roll the bubble area of ​​the film layer.

[0047] The top of the housing 1 is provided with a handle 15 for the operator to hold.

[0048] The specific usage method of this deaerator is as follows:

[0049] Step S10: Turn on the light panel 26, use the light beam to align the bubbles on the display panel 5, place the debubbler on the display panel 5 so that the tip of the needle 23 is above the bubbles.

[0050] Step 20: Push the second extrusion block 312 towards the first extrusion block 311 via the push rod 34. During the sliding process, the second extrusion block 312 flattens the membrane layer in the bubble area, and the air inside the bubble continuously concentrates into the notch 33. As the bubble volume is compressed, the membrane layer corresponding to the bubble bulges up, and the bulging membrane layer is punctured by the tip of the needle 23.

[0051] Step 30: Turn on the air pump 24. The air pump 24 draws air out through the gas channel inside the needle 23 so that the air inside the bubble is removed.

[0052] Step 40: Tilt the debubbler so that the roller 41 presses on the corresponding area of ​​the bubble. By rolling back and forth, the residual air in the bubble is further removed, and the film layer corresponding to the bubble area is smoothly adhered to the display panel 5.

[0053] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
