Description

Technical Field

[0001] The present invention relates to the technical field of backlight strip processing, and in particular to a backlight strip laminating jig. Background Art

[0002] At present, the light bar of the car backlight has a special fitting position, and its light bar PCB board itself is a soft flat cable structure with a slender shape. It can only be fitted manually. When fitting, the light bar is positioned with the edge of the back panel by hand. The lower end of the light bar PCB board is flush with the bottom of the back panel, and the thermal conductive glue behind the light bar is attached to the side wall of the back panel. Tweezers are needed to adjust during the fitting process. If the light bar is offset, it needs to be torn off and reworked. In addition, the fitting and pressure maintenance of such light bars are difficult to achieve by automatic equipment fitting.

[0003] The existing automotive backlight light bar lamination is mainly done manually, which is extremely difficult. The positioning is inaccurate during lamination, and the light bar is easily offset, causing the lamp beads on the light bar to float up and offset from the center of the light guide plate, resulting in various optical defects and other problems. Moreover, after the light bar is laminarized, it can only be pressed by fingers. The force is uneven during the pressure holding process, which may cause the light bar to fall off later, and the production efficiency is extremely low. On the other hand, the heat dissipation of the light bar mainly relies on the direct contact between the thermal conductive adhesive and the back plate. The heat generated by the lamp beads is transferred to the back plate through the thermal conductive adhesive for heat dissipation. After the light bar is reworked for the second time and the pressure is uneven, the thermal conductive adhesive cannot be completely attached to the back plate, affecting the heat dissipation of the light bar. Therefore, a backlight light bar lamination fixture is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

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

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, to achieve the above-mentioned purpose, the present invention provides a backlight strip laminating fixture, comprising: a base 1 and a laminating component 3 arranged in the base 1 , an upper cover 5 and a pressure-maintaining mechanism 6 arranged on the side of the upper cover 5 .

[0035] Among them, the top surface of the base 1 is provided with a placement groove 101, and the placement groove 101 is used to accommodate the back panel 2. Specifically, the base 1 and the placement groove 101 are designed according to the size model of the back panel 2 to ensure that after the back panel 2 is placed into the placement groove 101, the back panel 2 can be positioned to prevent the back panel 2 from shifting in the placement groove 101, thereby improving the stability of the positioning of the back panel 2.

[0036] The bonding component 3 is arranged in the placement groove 101, and the light bar 4 is placed on the first side of the bonding component 3, and the light bar 4 can be fixed on the side of the bonding component 3. In addition, thermal conductive adhesive is provided on the side of the light bar 4 away from the bonding component 3, and the thermal conductive adhesive is preliminarily bonded to the back panel 2. At this time, the bottom of the light bar 4 is flush with the bottom of the back panel 2, and the positioning of the light bar 4 is completed, effectively avoiding various optical defects caused by the displacement of the lamp beads (not shown in the figure) on the light bar 4 due to the floating position of the light bar 4 during bonding.

[0037] The upper cover 5 is rotatably connected to the base 1. Specifically, the upper cover 5 and the base 1 are hingedly connected to form a box body that can be freely opened. A pressure-holding mechanism 6 is provided on the side of the upper cover 5 facing the base 1. The pressure-holding mechanism 6 is used to hold the fitting component 3. The fitting component 3 is held by the pressure-holding mechanism 6 so that the fitting component 3 continuously and evenly applies force to various positions of the light bar 4 to maintain pressure on the light bar 4 so that the light bar 4 can be stably fitted on the back panel 2 to avoid the light bar 4 from falling off due to insufficient pressure maintenance during subsequent use, thereby affecting the heat dissipation of the light bar 4 and causing various problems.

[0038] When in use, in the initial state, open the upper cover 5, so that the upper cover 5 and the base 1 are laid flat on the work surface, the back panel 2 is placed in the placement groove 101, and the back panel 2 is stably limited by the placement groove 101, the light bar 4 is positioned on the side of the bonding component 3, and the bottom of the light bar 4 is flush with the bottom of the back panel 2, the positioning of the light bar 4 is completed, the position of the bonding component 3 is adjusted, and the thermal conductive glue set on the side of the light bar 4 away from the bonding component 3 is preliminarily bonded to the back panel 2, the upper cover 5 is closed, so that the bottom surface of the upper cover 5 is close to the top surface of the base 1, and the pressure holding mechanism 6 is controlled to hold the bonding component 3, so that the bonding component 3 continues to apply force evenly to each position of the light bar 4, and the light bar 4 is pressurized to make the light bar 4 stably bonded to the back panel 2, thereby completing the three functions of positioning, bonding and pressure holding of the light bar 4 in sequence, greatly reducing the difficulty of manual bonding of the production line workers, and greatly improving the qualified rate and production efficiency of the bonding of the light bar 4.

[0039] like Figure 4 and Figure 5 As shown, in one embodiment of the present invention, a first buckle 102 is set at the edge of the base 1, and a second buckle 501 is set at the edge of the upper cover 5. Specifically, the first buckle 102 is a female buckle, and the second buckle 501 is a male buckle. After flipping the upper cover 5, the first buckle 102 can be connected to the second buckle 501, so that the bottom surface of the upper cover 5 is close to the top surface of the base 1, thereby ensuring that the subsequent buckling mechanism can stably act on the fitting component 3.

[0040] In addition, the first buckle 102 can be snap-connected to the second buckle 501, so that the base 1 and the upper cover 5 can be stably docked, and the bonding component 3 can be further limited to prevent the bonding component 3 from causing the light bar 4 to move due to the support of the pressure-holding mechanism 6, thereby improving the qualified rate of the light bar 4 bonding.

[0041] like Figure 6 and Figure 7 As shown, the pressure-maintaining mechanism 6 includes: two mounting seats 601 symmetrically arranged on the side of the upper cover 5 facing the base 1, a linear sleeve 602 is integrally arranged at the left end of the mounting seat 601, and the linear sleeve 602 is slidably connected to the pressure rod 603. Specifically, a through hole is arranged at the axial position of the linear sleeve 602, and the through hole is used to pass the pressure rod 603. The pressure rod 603 is cylindrical as a whole, and the pressure rod 603 can be driven to push the fitting component 3 to move in the direction close to the light bar 4, thereby applying a supporting force.

[0042] In addition, a rotating shaft 604 is arranged at the right end of the mounting seat 601, and the rotating shaft 604 is rotatably connected to the handle 605, and the axis of the rotating shaft 604 serves as the rotation center of the handle 605, wherein the rotation center does not coincide with the axis of the linear sleeve 602. Preferably, the rotation center is located below the axis of the linear sleeve 602, and the handle 605 is connected to the pressure rod 603 through the transmission connecting rod 606. By rotating the handle 605, the transmission connecting rod 606 can be driven to move, thereby driving the pressure rod 603 to perform reciprocating telescopic motion along the axial direction of the linear sleeve 602.

[0043] It should be noted that when the lower end of the handle 605 is at the right limit position, the pressure rod 603 is at the right limit position relative to the linear sleeve 602. At this time, the pressure rod 603 will not apply a holding force to the fitting component 3, and will not affect the flipping of the upper cover 5 to fit it with the base 1. When the lower end of the handle 605 is at the left limit position, the pressure rod 603 is at the left limit position relative to the linear sleeve 602. At this time, the pressure rod 603 will apply the maximum holding force to the fitting component 3.

[0044] It should be further explained that the upper end of the handle 605 is set to an equilateral triangle shape, and the upper end of the handle 605 is provided with a first assembly groove 607, and the right end of the transmission connecting rod 606 is clamped into the first assembly groove 607. At the same time, a first connecting hole is set at the position of the first assembly groove 607, and the left end of the transmission connecting rod 606 is connected to the second connecting hole. The right end of the transmission connecting rod 606 is locked in the first assembly groove 607 by passing a pin through the first connecting hole and the second connecting hole. Correspondingly, the transmission connecting rod 606 is C-shaped as a whole. The handle 605 is shaped like a left limit, and the opening of the rotating shaft 604 faces upward. When the lower end of the handle 605 is located at the left limit position, the hinge point between the handle 605 and the transmission connecting rod 606 coincides with the axis of the pressure rod 603. At this time, the bottom surface of the first assembly groove 607 will abut the side of the transmission connecting rod 606 to limit the handle 605 from continuing to rotate. At this time, the length direction of the handle 605 is perpendicular to the axis direction of the pressure rod 603, and the pressure rod 603 moves to the limit position in the direction close to the bonding component 3, and the pressure rod 603 applies the maximum holding force to the bonding component 3. On the other hand, since the hinge point between the handle 605 and the transmission connecting rod 606 coincides with the axis of the pressure rod 603, even when the lower end of the handle 605 is no longer subjected to the force applied by the outside world, the upper end of the handle 605 is subjected to the reaction force applied by the bonding component 3, so that the handle 605 is self-locking as a whole, thereby ensuring that the bonding component 3 continues to remain in a compressed state, effectively reducing the work intensity of the staff.

[0045] Of course, a limit pin 8 can also be set on the side of the upper cover 5 facing the base 1. The limit pin 8 is specifically set at the lower left of the mounting seat 601. When the lower end of the handle 605 is at the left extreme position and the length direction of the handle 605 is perpendicular to the axial direction of the pressure rod 603, the mounting seat 601 is used to prevent the handle 605 from further rotating. The purpose is to reduce the interaction force between the first assembly groove 607 and the transmission connecting rod 606, prevent it from being frequently subjected to force and reducing the accuracy, and play a role in extending the service life of the pressure maintaining mechanism 6.

[0046] Preferably, a second assembly groove 608 is set at the right end of the pressure rod 603, and the left end of the transmission link 606 is snapped into the second assembly groove 608. At the same time, a third connecting hole is set at the position of the second assembly groove 608, and the left end of the transmission link 606 is connected to the fourth connecting hole. A pin is passed through the third connecting hole and the fourth connecting hole to lock the left end of the transmission link 606 in the second assembly groove 608 without affecting the free rotation of the left end of the transmission link 606 relative to the right end of the pressure rod 603.

[0047] To ensure the synchronous movement of the two pressure rods 603 in the pressure-holding mechanism 6, a connecting rod mechanism (not shown in the figure) can be optionally provided on the side of the upper cover 5 facing the base 1. The connecting rod mechanism is used to control the synchronous movement of the two handles 605, thereby ensuring the synchronous movement of the two pressure rods 603 in the pressure-holding mechanism 6, thereby uniformly applying force to each position in the length direction of the fitting base 301, making the light strip 4 uniformly stressed along its length direction, thereby improving the fitting quality of the light strip 4.

[0048] In one embodiment of the present invention, an operating port 7 for inserting a handle 605 is provided on the base 1. The operating port 7 is generally in the shape of a strip, and the movement path of the handle 605 can be further limited by the operating port 7. Specifically, when the upper cover 5 is flipped over and fits against the base 1, the symmetrical side surfaces of the operating port 7 respectively fit against the symmetrical side surfaces of the handle 605, thereby limiting the handle 605, so that the handle 605 rotates counterclockwise in a plane with the axis of the rotating shaft 604 as the rotation center, thereby ensuring the overall movement accuracy of the pressure maintaining mechanism 6.

[0049] like Figure 8 and Fig. 9 As shown, the fitting component 3 includes: a fitting base 301, and a contoured foam 303 is arranged on the first side of the fitting base 301. The contoured foam 303 can be cut into different shapes according to the shape of the light bar 4, so that the light bar 4 can be better positioned in the fitting component 3. Moreover, it can fit the surface of the light bar 4 more closely, avoiding the light bar 4 from shifting or falling off during the fitting process, thereby improving the quality of the fitting of the light bar 4. Furthermore, the contoured foam 303 can directly contact the lamp beads on the light bar 4, and because of its material property of being able to absorb external impact force, it can avoid the lamp beads of the light bar 4 from being damaged during pressure maintenance. On the other hand, the contoured foam 303 is connected to the fitting base 301 by adhesive bonding, which is convenient for replacing the contoured foam 303 later, and effectively avoiding the deformation of the contoured foam 303 due to long-term use, thereby reducing the positioning accuracy of the light bar 4.

[0050] In one embodiment of the present invention, a stepped groove 304 is provided on the side of the contoured foam 303 facing away from the fitting base 301. Specifically, the side surface of the stepped groove 304 fits the light bar 4, and the top surface of the stepped groove 304 fits the top surface of the light bar 4 to ensure that the bottom of the light bar 4 is flush with the bottom of the back panel 2, thereby facilitating the positioning of the light bar 4.

[0051] In addition, a receiving hole 305 is provided on the side of the stepped groove 304, and the receiving hole 305 is used to accommodate the lamp beads on the light strip 4. By adapting a lamp bead of the light strip 4 to each receiving hole 305, the positioning of the light strip 4 is further facilitated, and the light strip 4 can be quickly positioned. Moreover, the setting of the receiving hole 305 can provide the necessary conditions for subsequent uniform pressure maintenance.

[0052] In one embodiment of the present invention, two parallel positioning ribs 302 are provided on both end surfaces of the fitting base 301, and the two positioning ribs 302 form a positioning groove. A positioning protrusion 105 is provided on the inner side of the base 1, and the positioning groove is slidably connected to the positioning protrusion 105. The positioning groove and the positioning protrusion 105 cooperate with each other to form a preliminary limit for the fitting base 301, so as to ensure that the fitting base 301 can be stably placed in the placement groove 101. At the same time, the positioning groove and the positioning protrusion 105 have a certain reserved gap to ensure that when the pressure-keeping mechanism 6 holds the fitting base 301, the fitting base 301 can drive the light bar 4 to move in the direction close to the back plate 2, thereby ensuring that the light bar 4 can be accurately fitted on the back plate 2.

[0053] Furthermore, a guide rail (not shown in the figure) is provided in the placement groove 101. Specifically, when the upper cover 5 is attached to the base 301, the length direction of the guide rail is consistent with the axial direction of the pressure rod 603, and the guide rail is slidably connected to the attached base 301. The movement path of the attached base 301 is further limited by the guide rail, thereby effectively ensuring that the attached base 301 evenly applies a supporting force to the light bar 4.

[0054] It should be noted that limiting bosses 104 are set at the four corners of the top surface of the base 1. Specifically, the limiting bosses 104 are set according to the size and shape of the back panel 2. After the back panel 2 is placed into the placement groove 101, the inner side surface of the limiting boss 104 just abuts against the side surface at the corner of the back panel 2, thereby limiting the back panel 2 and ensuring that the position of the back panel 2 in the placement groove 101 can always remain unchanged during the process of the light strip 4 being fitted on the back panel 2, thereby improving the accuracy of the light strip 4 being fitted on the back panel 2.

[0055] In order to ensure that each lamp bead on the light bar 4 enters the corresponding receiving hole 305 and whether the bottom surface of the light bar 4 is aligned with the bottom surface of the back plate 2, a plurality of pressure sensors 307 are selected to be arranged on the side of the fitting base 301 that is fitted with the light bar 4. The plurality of pressure sensors 307 are arranged equidistantly along the length direction of the fitting base 301. The pressure sensors 307 are located on the inner side of the profiling foam 303, that is, the profiling foam 303 is bonded to the side of the plurality of pressure sensors 307 by means of the back adhesive. When the pressure-maintaining mechanism 6 holds the fitting base 301, the plurality of pressure sensors 307 are used to press the pressure of the pressure sensor 307. 7 can detect whether the force is uniform at each position along the length direction of the light bar 4. When the force is uneven at each position along the length direction of the light bar 4, it is determined that the position of the light bar 4 relative to the contoured foam 303 has shifted. At this time, the staff opens the upper cover 5, further observes and adjusts the position of the light bar 4, until the pressure-maintaining mechanism 6 supports the fitting base 301, and several pressure sensors 307 detect that the force is uniform at each position along the length direction of the light bar 4, and then further increases the force applied by the pressure-maintaining mechanism 6 to the fitting base 301 to complete the fitting of the light bar 4. The above can effectively ensure that the light bar 4 is accurately fitted to the back plate 2, while protecting the lamp beads from being damaged by pressure.

[0056] Furthermore, if the position of the light bar 4 relative to the contoured foam 303 does not shift, then observe whether the contoured foam 303 is damaged or deformed and whether the pressure-holding mechanism 6 provides a uniform holding force to the fitting base 301. Whether the contoured foam 303 is damaged or deformed can be determined by observation. In order to timely determine whether the pressure-holding mechanism 6 provides a uniform holding force to the fitting base 301, select to set scale lines on the outer peripheral side of the pressure rod 603. By observing the scale lines, it is determined whether the two pressure rods 603 move synchronously, and then quickly determine whether the pressure-holding mechanism 6 provides a uniform holding force to the fitting base 301. In addition, an observation window is set on the surface of the upper cover 5. The observation window is made of tempered glass. Through the observation window, it is further assisted to observe whether the lamp beads shift before being held by the pressure-holding mechanism 6, so that the position state of the light bar 4 can be discovered and adjusted in time.

[0057] An extension protrusion 306 is provided on one side of the fitting base 301 that is fitted with the light bar 4. The extension protrusion 306 extends toward the direction close to the light bar. The extension protrusion 306 is in a strip shape. The bottom surface of the extension protrusion 306 fits with the top surface of the contoured foam 303 to increase the fitting area between the fitting base 301 and the contoured foam 303 and improve the installation reliability of the contoured foam 303. Furthermore, the top of the extension protrusion 306 is lower than the top of the fitting base 301, which can save material for the extension protrusion 306.

[0058] In one embodiment of the present invention, a first leaf 901 is provided on the side of the base 1, and the first leaf 901 is installed on the side of the base 1 by screws. A second leaf 902 is provided on the side of the upper cover 5, and the second leaf 902 is installed on the side of the upper cover 5 by screws. The first leaf 901 is connected to the second leaf 902 by a pin shaft to form a hinge 9, thereby connecting the base 1 and the upper cover 5 together to form a complete box body.
