Description

Technical Field

[0001] This invention relates to the field of backlight processing technology, and more specifically, to a pressure fixture for assembling a three-in-one vehicle-mounted MINILED backlight. Background Technology

[0002] The assembly of the thermally conductive adhesive, lamp board, and reflective film for automotive MiniLED backlights requires high precision and efficiency. All three components need to be quickly and accurately aligned and activated under pressure to ensure rapid and accurate assembly and secure mounting to the entire inner surface of the lower frame. Current assembly equipment only has a pressing function, requiring manual mounting by production personnel, which easily leads to various problems, such as:

[0003] 1. The lower iron frame and the thermal conductive adhesive / light board / reflective film (three parts) cannot be accurately aligned. Manual alignment and assembly can easily lead to misalignment of the lower iron frame and the thermal conductive adhesive / light board / reflective film (the assembly accuracy cannot be guaranteed by manual alignment and assembly).

[0004] 2. Applying pressure manually to bond the iron frame to the thermally conductive adhesive / light panel / reflective film (three components) is time-consuming and labor-intensive, and it is impossible to guarantee a uniform distribution of the pressure (the bonding and pressing force between the two cannot be guaranteed to be uniformly distributed for the pressurized product).

[0005] 3. Misalignment during assembly can cause damage to the LEDs and NTC thermistors on the LED board PCBA during the pressurization process.

[0006] 4. Vehicle-mounted reliability requirements are high. Manually assembled backlights are difficult to pass comprehensive automotive-grade reliability tests and are prone to issues such as loosening or detachment of the lamp panel.

[0007] 5. Manual assembly with pressure is inefficient and will significantly increase costs. Summary of the Invention

Detailed Implementation

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0050] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0051] like Figures 1-10 As shown, this invention provides a three-in-one assembly and pressurization fixture for vehicle-mounted MINILED backlights, including: an upper mold 1, a lower mold 2, and a base 3. It should be noted that the base 3 described in this application is a collection of devices capable of mounting the upper mold 1, lower mold 2, and other equipment and structures. It can be a mounting frame with a platform or a mounting platform with a housing. Any commercially available product or existing technology capable of mounting the upper mold 1, lower mold 2, and related fixture structures can be used as the base 3 in this application. The base 3 is also equipped with related electrical equipment, including but not limited to a pressure input terminal 32, a power input terminal and power switch 33, PLC control 34, negative pressure monitoring 35, emergency stop / reset switch 36, start switch 37, vacuum switch 38, pressure regulating valve / pressure gauge 39, etc., as shown in the specific locations. Figure 1 As shown.

[0052] The upper mold 1 is connected to the base 3 through a displacement component. The displacement component can drive the upper mold 1 to move. The movement methods include but are not limited to vertical translation, horizontal translation, forward and backward translation, flipping the upper mold 1 and rotating the upper mold 1. The main function of the displacement component is to transport the backlight component 4 placed on the upper mold 1 to the lower mold 2 and provide downward pressure to install the backlight component 4 on the assembly 5. At the same time, it can also facilitate the operator to place the backlight component 4 on the upper mold 1.

[0053] The lower mold 2 is located below the upper mold 1 and is connected to the base 3 through an adjustment component. The adjustment component can adjust the relative position of the lower mold 2 and the upper mold 1, including but not limited to vertical translation, horizontal translation, forward and backward translation, rotation of the lower mold 2, and flipping of the lower mold 2. The base 3 is equipped with a control unit. In addition to the displacement component being electrically connected to the control unit, related electrical equipment installed on the housing is also electrically connected to the control unit.

[0054] The upper mold 1 uses a displacement component to sequentially place the backlight assembly 4 (including thermally conductive adhesive 41, lamp board 42, and reflective film 43) into the assembly 5, and provides pressure for the installation of the backlight assembly 4 in the assembly 5. The upper mold 1 is provided with positioning posts 11, and positioning holes are provided on the thermally conductive adhesive 41, lamp board 42, and reflective film 43. The backlight assembly 4 can be quickly installed on the upper mold 1 through the positioning posts 11, thereby realizing the rapid installation of the thermally conductive adhesive 41, lamp board 42, and reflective film 43.

[0055] The lower mold 2 is used to provide positioning for the assembly 5 and to fix the assembly 5.

[0056] Furthermore, when the upper mold 1 moves the backlight assembly 4 downward, if it is only positioned by the positioning post 11, the backlight assembly 4 may fall off the upper mold 1, especially the lamp panel 42, because its weight is large and the risk of falling off is also large. In order to avoid the risk of falling off, this application also includes a negative pressure device. The upper mold 1 is made of urethane and has adsorption holes 12. The adsorption holes 12 of the upper mold 1 (through pipeline and air pressure input terminal 32) are connected to the negative pressure device. The negative pressure device is electrically connected to the control unit (as well as the negative pressure monitoring 35 and vacuum switch 38).

[0057] By setting up a negative pressure device, after the backlight assembly 4 is placed on the upper mold 1, it can be held in place by negative pressure. The positioning holes on the thermal conductive adhesive 41, the lamp plate 42, and the reflective film 43 are aligned with the positioning post 11 of the upper mold 1 as a reference. The three components can be accurately positioned and adsorbed onto the upper mold 1, preventing the backlight assembly 4 from falling off the upper mold 1.

[0058] Furthermore, to prevent the LEDs (light beads) and NTCs (thermometers) from being damaged by impacts during installation, the upper mold 1 is usually provided with clearance grooves 13 at the corresponding positions.

[0059] Furthermore, the shape of assembly 5 varies for different vehicles, but assembly 5 usually has a frame protruding from assembly 5 for mounting backlight assembly 4, which is commonly referred to in the industry as a metal frame. In order to enable quick replacement of assembly 5 and to make lower mold 2 applicable to different models of assembly 5, we have made further optimizations to lower mold 2.

[0060] The top surface of the lower mold 2 is provided with a limiting component 21, a positioning groove 22, and a positioning block 23. The opening area of ​​the positioning groove 22 is adapted to the (maximum) area of ​​the iron frame of the backlight assembly (currently available in commercial vehicles). In order to accommodate assemblies 5 of other sizes, multiple opening slots are provided on the side wall of the positioning groove 22. Usually, the number of opening slots is at least four, located on the four sides of the positioning groove 22. Preferably, the number of opening slots is eight, two on each side. The positioning block 23 is set in the opening slot. To facilitate the adjustment of the position of the positioning block 23, a threaded hole can be provided in the opening slot. A stepped strip hole is provided on the positioning block 23. A screw is placed in the strip hole, and the screw passes through the strip hole and connects to the threaded hole. The positioning block 23 is fixed by pressing the screw on the step of the strip hole. Figure 8 As shown, this achieves the movable connection between the positioning block 23 and the lower mold 2. When replacing different models of assemblies, only the position of the positioning block 23 needs to be adjusted to quickly set the limit of the assembly 5 of that model. To facilitate the replacement of the assembly 5, the limiting component 21 is usually designed to adapt to the shape of the back of the assembly 5. Thus, when replacing the assembly, quick positioning can be achieved through the positioning groove 22 and the positioning block 23. The limiting component 21 achieves quick horizontal limiting of the assembly 5 without the need for any fixing structure (such as screws, clips, etc.) to fix the assembly again. This allows the lower mold 2 to accurately position the iron frame (of the assembly 5), and the iron frame can remain stable and not move when assembling the three components (thermal conductive adhesive 41, lamp plate 42, and reflective film 43).

[0061] The working principle and beneficial effects of the above technical solution are as follows: The anti-cavity groove 13 can protect the LED (light bead) and NTC (thermistor) and prevent them from being impacted; the relative position between the lower mold 2 and the upper mold 1 can be adjusted by the adjustment component, and the pressure can be ensured to be uniform by the displacement component, which can fully activate the adhesive of the backlight component 4, and the adhesive can be firmly attached, avoiding uneven pressure on the product.

[0062] The positioning groove 22 and positioning block 23 of the lower mold 2 can realize the quick positioning of the iron frame of the assembly 5. Together with the upper mold 1, it can realize the quick positioning and assembly of the thermally conductive adhesive 41, the lamp board 42, the reflective film 43 and the iron frame, ensuring the accurate bonding of the iron frame with the thermally conductive adhesive 41, the lamp board 42 and the reflective film 43. While realizing the quick upper and lower alignment assembly, it ensures the assembly accuracy.

[0063] The displacement component can drive the upper mold 1 to fit with the assembly 5 (i.e., the iron frame), so that the upper mold 1 and the lower mold 2 remain parallel. It can also control the pressure holding time and pressure intensity through the PLC.

[0064] The above structural design allows the Miniled light board to be firmly adhered, and the thermally conductive adhesive 41 can fully activate the adhesion, meeting various high requirements and reliability test requirements, improving efficiency, and reducing costs.

[0065] It has been verified that a three-in-one assembly pressure fixture can assemble three parts in just one minute, which significantly improves production efficiency compared to existing technologies.

[0066] In the foregoing embodiments, we mentioned that the movement of the displacement component includes, but is not limited to, vertical translation, horizontal translation, forward and backward translation, flipping the upper mold 1, and rotating the upper mold 1. The main function of the displacement component is to transport the backlight component 4 placed on the upper mold 1 into the lower mold 2 and to provide downward pressure to install the backlight component 4 onto the assembly 5. Therefore, theoretically, the displacement component only needs to have the vertical translation movement. However, if it is just a simple vertical translation, the upper mold 1 only needs to face the lower mold 2. But a simple vertical translation is very inconvenient for the installation of the backlight component 4. Therefore, in order to facilitate the operator to place the backlight component 4 on the upper mold 1, the displacement component also needs to have the ability to flip. That is, when installing the backlight component 4, the displacement component flips the upper mold 1 to face the operator. After the operator installs the thermal conductive adhesive 41, the lamp plate 42, or the reflective film 43, the displacement component flips the upper mold 1 to face the lower mold 2 and then moves down. This makes it easier to install the backlight component 4 on the upper mold 1, thereby improving production efficiency.

[0067] Furthermore, additional functions such as forward and backward translation, left and right translation, or horizontal rotation of the upper mold 1 can be added to further optimize the operator's working position. Since these three functions are only for adapting to the site or optimizing the comfort of manual operations, they have little impact on improving production efficiency.

[0068] In this embodiment, we provide an implementation that allows the upper mold 1 to have both vertical translation and flipping functions. As one of many implementations, the displacement component consists of a first adjustment component and a second adjustment component. The first adjustment component is disposed on the base 3, the second adjustment component is disposed on the first adjustment component, and the upper mold 1 is disposed on the second adjustment component.

[0069] The first adjustment component can drive the upper mold 1 to move up and down, which is used to adjust the distance between the upper mold 1 and the lower mold 2 and the pressure applied.

[0070] The second adjustment component can flip the upper mold 1 to adjust the angle between the upper mold 1 and the lower mold 2, so that the upper mold 1 can switch back and forth between facing the operator and facing the lower mold 2.

[0071] The first adjustment assembly includes a first driving device 61, a first transmission component 62, and a first mounting component 63. The first driving device 61 is mounted on the base 3. The first mounting component 63 is connected to the first driving device 61 via the first transmission component 62. As one of many embodiments, the first driving device 61 can be a motor with gears. The first transmission component 62 can consist of a screw, a threaded sleeve, and a fixed sleeve. The fixed sleeve is mounted on the base 3, making the first transmission component 62 and the base 3 integral. The screw passes through the fixed sleeve and is shaft-connected to the fixed sleeve, allowing rotation between the screw and the fixed sleeve without vertical movement. The threaded sleeve is fitted onto the screw and connected to the first mounting component 63. When the screw rotates, the threaded sleeve drives the first mounting component 63 to move vertically. A gear is also provided at the end of the screw and is connected to the motor gear via a belt, thereby achieving transmission. Figure 2 As shown.

[0072] Furthermore, the second adjustment component is disposed on the first mounting member 63, so that when the first mounting member 63 moves up and down, the second adjustment component can move up and down with it.

[0073] Furthermore, in order to ensure that the upper mold 1 does not wobble when moving up and down, the first mounting component 63 is provided with a slider 631, and the base 3 is provided with a slide rail 31. The first mounting component 63 is movably connected to the slide rail 31 through the slider 631, thereby ensuring that the upper mold 1 does not wobble during the up and down movement, thus ensuring the accuracy of the backlight assembly 4 assembly.

[0074] Furthermore, the second adjustment component includes a second driving device 71, a second transmission component 72, and a second mounting component 73. The second driving device 71 is disposed on the first mounting component 63. One end of the second driving device 71 is movably connected to the first mounting component 63, and the other end is movably connected to the second transmission component 72. The second transmission component 72 is disposed on the second mounting component 73, and the second mounting component 73 is movably connected to the first mounting component 63. The upper mold 1 is disposed on the second mounting component 73.

[0075] As one of many implementation methods, the second drive device 71 can be a telescopic motor with a telescopic rod. The second mounting member 73 and the first mounting member 63 are connected by a shaft, allowing the second mounting member 73 to rotate relative to the first mounting member 63, thereby achieving the flipping of the upper mold 1 mounted on the second mounting member 73. The end of the telescopic motor away from the telescopic rod is shaft-connected to the first mounting member 63, and the end of the telescopic rod away from the telescopic motor is shaft-connected to the second transmission member 72. The second transmission member 72 can be a bushing capable of mounting a rotating shaft, such as… Figure 3 , Figure 4 As shown, when the telescopic motor is started, the telescopic rod extends, pushing the second mounting part 73 to rotate, thereby flipping the upper mold 1.

[0076] In the foregoing embodiments, we mentioned that the adjustment component can adjust the relative position of the lower mold 2 and the upper mold 1. The adjustment methods include, but are not limited to, vertical translation, horizontal translation, forward and backward translation, rotation of the lower mold 2, and flipping of the lower mold 2. Since the upper mold 1 can adjust the parallelism between itself and the lower mold 2 by flipping the second adjustment component, the main function of the lower mold 2 is usually to adjust the position of the lower mold 2 on the horizontal plane. That is, the lower mold 2 only needs to be able to translate horizontally, translate forward and backward, and rotate at an angle on the horizontal plane.

[0077] Furthermore, functions such as vertical translation and tilting can be added to further optimize the operator's working position. Since these two functions are only for adapting to the site or optimizing the comfort of manual work, they have little impact on improving production efficiency.

[0078] In this embodiment, we provide a lower mold 2 that can perform forward and backward translation, left and right translation, and angle adjustment on the horizontal plane. In order to avoid the upper mold 1 colliding with the iron frame due to positional shift after replacing different models of assembly 5, the lower mold 2 also needs to have the function of precise adjustment.

[0079] In this embodiment, the adjustment assembly consists of a translation adjustment component 8 and an angle adjustment component 9. The angle adjustment component 9 is disposed on the base 3, the translation adjustment component 8 is disposed on the angle adjustment component 9, and the lower mold 2 is disposed on the translation adjustment component 8.

[0080] The translation adjustment component 8 is used to adjust the position of the lower mold 2 on the X-axis and Y-axis;

[0081] The angle adjustment component 9 is used to adjust the rotation angle of the lower mold 2 on the horizontal plane.

[0082] The angle adjustment component 9 consists of a first mounting plate 91, a first fine-tuning device 92, and a second fine-tuning device 93. The first fine-tuning device 92 and the second fine-tuning device 93 are mounted on the base 3. The first mounting plate 91 is mounted on the base 3 and is movably connected to the base 3. The first fine-tuning device 92 and the second fine-tuning device 93 abut against the side wall of the first mounting plate 91. The first fine-tuning device 92 and the second fine-tuning device 93 can be micrometers and are fixed to the base 3 by fixing blocks. The two fine-tuning devices enable precise adjustment of the rotation angle of the first mounting plate 91.

[0083] To achieve the movable connection between the first mounting plate 91 and the base 3, we provide the following two implementation methods.

[0084] In the first embodiment, an arc-shaped hole is provided on the first mounting plate 91, the center of which is the rotation center of the first mounting plate 91. Typically, there are two arc-shaped holes, which are concentric arcs. A step can be provided within the arc-shaped hole. A threaded hole is provided on the base 3, and a screw is passed through the arc-shaped hole to connect to the threaded hole of the base 3. The first mounting plate 91 is fixed by the step within the arc-shaped hole. Figure 9 As shown.

[0085] In the second embodiment, the bottom center of the first mounting plate 91 is connected to the base 3 shaft. For example, a threaded hole can be provided at the bottom of the first mounting plate 91, and a through hole can be provided on the base 3. A screw is passed through the through hole and connected to the threaded hole at the bottom of the first mounting plate 91, and the screw acts as a rotating shaft.

[0086] Furthermore, the translation adjustment component 8 is composed of a second mounting plate 81 disposed on the first mounting plate 91, a first movable plate 82 disposed on the second mounting plate 81, a second movable plate 83 disposed on the first movable plate 82, a third fine-tuning device 84, and a fourth fine-tuning device 85; the second mounting plate 81 is located at the rotation center of the first mounting plate 91, and when the first mounting plate 91 rotates, it can drive the second mounting plate 81 to rotate.

[0087] The bottom surface of the first movable plate 82 is movably connected to the top surface of the second mounting plate 81. Typically, the bottom surface of the first movable plate 82 is provided with a sliding groove, and the top surface of the second mounting plate 81 is provided with a sliding rail. Figure 9 As shown, the third fine-tuning device 84 is disposed on the side wall of the second mounting plate 81 and abuts against the first abutting member 821 on the side wall of the first movable plate 82. The third fine-tuning device 84 can be a micrometer, used to precisely adjust the position of the first movable plate 82.

[0088] The bottom surface of the second movable plate 83 is movably connected to the top surface of the first movable plate 82. Typically, the bottom surface of the second movable plate 83 is provided with a sliding groove, and the top surface of the first movable plate 82 is provided with a sliding rail. Figure 9As shown, the fourth fine-tuning device 85 is disposed on the side wall of the first movable plate 82 and abuts against the second abutting member 831 on the side wall of the second movable plate 83. The fourth fine-tuning device 85 can be a micrometer, used to precisely adjust the position of the second movable plate 83.

[0089] The lower mold 2 is set on the top of the second movable plate 83. Both the first movable plate 82 and the second movable plate 83 are provided with strip holes, and the length direction of the strip holes is the translation direction of their respective translation directions. The translation directions of the first movable plate 82 and the second movable plate 83 are perpendicular.
