Description

Technical Field

[0001] The present invention relates to the technical field of backlight module assembly, and specifically to a semi-automatic assembly jig for a backlight assembly light bar of a vehicle-mounted general screen. Background Art

[0002] The crystal screen itself does not emit light and requires a backlight source to illuminate the pixels to display images. Therefore, the LED backlight source, this seemingly insignificant but crucial component, is the key for the liquid crystal display to be able to display images and text normally.

[0003] The commonly used backlight modules currently include a light guide plate, a light bar, and a housing. Double-sided tape is pre-attached to the side wall of the housing, and then the light bar is attached to the side wall of the housing manually, and then the light guide plate is placed in the housing to complete the installation.

[0004] For the above technical conditions, there are still defects that due to the small space on the side wall of the housing and the small size of the light bar, it is inconvenient for the staff to attach and align after grasping the light bar, resulting in low efficiency.

[0005] Based on this, the present invention designs a semi-automatic assembly jig for a backlight assembly light bar of a vehicle-mounted general screen to solve the above problems. Summary of the Invention

[0006] To achieve the above object, the present invention provides the following technical solution: A semi-automatic assembly jig for a backlight assembly light bar of a vehicle-mounted general screen, including an installation table for placing the housing, a light bar attaching mechanism, and a lifting mechanism. A lifting plate is movably arranged on the lifting mechanism. The light bar attaching mechanism includes an attaching plate, a first cylinder, and a suction pipe. The first cylinder is fixedly arranged on the lifting plate. An installation plate is fixedly arranged on the telescopic shaft of the first cylinder. The attaching plate is fixedly arranged on the installation plate. The attaching plate is provided with adsorption holes, and the adsorption holes communicate with the suction pipe. The adsorption holes adsorb the light bar. The first cylinder drives the attaching plate to move towards the side wall of the housing. After the light bar is attached to the side wall of the housing, the adsorption holes stop adsorbing.

[0007] By adopting the above technical solution, when attaching the light bar, place the housing on the installation table, and then drive the lifting mechanism and the first cylinder to make the attaching plate move towards the side wall of the housing. When the light bar is attached to the side wall of the housing, at this time, the adsorption holes no longer adsorb, and the light bar is released, so as to attach the light bar to the housing, achieving the effect of facilitating the attachment of the light bar.

[0008] Preferably, a pressure sensor is fixedly arranged on the installation plate, the attaching plate is fixedly connected to the pressure sensor, and a display screen is fixedly arranged on the lifting plate. The pressure sensor is electrically connected to the display screen.

[0009] By adopting the above technical solution, when attaching the light strip, the pressure sensor detects the pressure during attachment, so as to determine whether the corresponding light strip is attached to the side wall of the housing after moving a specified distance.

[0010] Preferably, a plurality of the first cylinders are arranged on the lifting plate, and the pressure sensors on the plurality of first cylinders are respectively fixedly connected to the same attachment plate.

[0011] By adopting the above technical solution, a plurality of pressure sensors are provided to improve the accuracy of detecting the attachment pressure.

[0012] Preferably, a guiding groove is formed on the attachment plate, the light strip is located in the guiding groove, and the upper side wall of the light strip contacts the groove wall of the guiding groove.

[0013] By adopting the above technical solution, a guiding groove is provided. When installing the light strip on the attachment plate, it is convenient to align the light strip and improve the accuracy during attachment.

[0014] Preferably, a guiding block is fixedly arranged on the attachment plate, and the guiding block is located above the guiding groove.

[0015] By adopting the above technical solution, when attaching the light strip, the guiding block can further guide the staff to attach the light strip and facilitate the alignment of the staff.

[0016] Preferably, a second cylinder is fixedly arranged on the side wall of the attachment plate, a stop bar block is fixedly arranged on the telescopic shaft of the second cylinder, and the stop bar block moves up and down along the side wall of the attachment plate. When the light strip is adsorbed on the adsorption hole, one end of the light strip contacts the stop bar block.

[0017] By adopting the above technical solution, when the light strip is installed on the attachment plate, one end of the light strip contacts the stop bar block, reducing the lateral movement of the light strip, facilitating the lateral positioning of the light strip, and achieving the effect of further facilitating the positioning of the staff.

[0018] Preferably, air suction holes are formed on the side wall of the adsorption plate, the air suction holes communicate with the adsorption holes, and the air suction holes adsorb the redundant light strip.

[0019] By adopting the above technical solution, after the light strip is attached to the attachment plate, the redundant light strip is adsorbed on the air suction holes to prevent the redundant light strip from protruding, further facilitating the staff to attach the light strip.

[0020] Preferably, a placement groove is formed on the installation table, and the housing is placed in the placement groove.

[0021] By adopting the above technical solution, after placing the housing, the movement of the housing is reduced and the placement of the housing is stabilized.

[0022] Preferably, a pressure display meter is fixedly arranged on the air suction pipe.

[0023] By adopting the above technical solution, when the attaching plate adsorbs the lamp strip, the pressure change of the air suction pipe is observed through the pressure display meter. When the required pressure value is not reached in the air suction pipe, it indicates that the air suction holes do not adsorb the lamp strip.

[0024] Preferably, after the lamp strip is attached to the side wall of the housing, the adsorption holes do not stop adsorption, the adsorption force of the air suction pipe is reduced, and the adsorption force is less than the adhesion force of the lamp strip on the housing.

[0025] By adopting the above technical solution, when the adsorption plate moves, the adsorption holes with a smaller suction force slightly adsorb the lamp strip. At this time, observing the pressure display, when the pressure value is not reset, it indicates that some lamp strips are not attached to the housing.

[0026] In summary, the present application has the following beneficial technical effects: when attaching the lamp strip, the housing is placed on the installation table, and then the lifting mechanism and the first cylinder are driven to move the attaching plate towards the side wall of the housing. After the lamp strip is attached to the side wall of the housing, at this time the adsorption holes no longer adsorb, and the lamp strip is released, so as to attach the lamp strip to the housing, achieving the effect of convenient attachment of the lamp strip.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0037] The following is a further detailed description of the present application in conjunction with the attached Figure 1-6 This application will be further described in detail.

[0038] Refer to Figure 1-Figure 6 A semi-automatic assembly jig for the light bar of a vehicle-mounted general-purpose screen backlight assembly includes a mounting table 1 for placing the outer shell 13, an attaching mechanism, and a lifting mechanism 2. The lifting mechanism 2 in this embodiment can be a cylinder or a motor screw mechanism, which is a conventional structure and will not be elaborated here. A lifting plate 3 is movably arranged on the lifting mechanism 2, and the lifting mechanism 2 drives the lifting plate 3 to lift and lower. The attaching mechanism includes an attachment plate 4, a first cylinder 5, and a suction pipe 6. The first cylinder 5 is fixedly arranged on the lifting plate 3, and a mounting plate 7 is fixedly arranged on the telescopic shaft of the first cylinder 5. A pressure sensor 8 is fixedly arranged on the mounting plate 7, and the attachment plate 4 is fixedly arranged on the pressure sensor 8. There are multiple first cylinders 5 arranged on the lifting plate 3. In this embodiment, three are provided, and the three pressure sensors 8 are respectively fixedly arranged on the same attachment plate 4;

[0039] Refer to Figure 1-Figure 6 On the lateral side wall of the attachment plate 4, a guide groove 9 is opened, and adsorption holes 10 are opened in the guide groove 9. There are multiple adsorption holes 10. An air vent cavity (not shown in the figure) is opened on the attachment plate 4, and the multiple adsorption holes 10 communicate with the air vent cavity respectively. The attachment plate 4 is fixedly connected to the suction pipe 6. The suction pipe 6 is a flexible pipe. The suction pipe 6 communicates with the air vent cavity. A suction pump 11 is arranged on the side close to the mounting table 1. The suction pipe 6 is connected to the suction pump 11. A suction hole 12 is opened on the longitudinal side wall of the adsorption plate, and the suction hole 12 communicates with the air vent cavity. A placement groove 14 is opened on the mounting table 1, and the outer shell 13 is placed in the placement groove 14. Placing the outer shell 13 in the placement groove 14 can prevent the outer shell 13 from moving around and stabilize the placement of the outer shell 13. Double-sided tape is pre-attached to the lateral side wall of the outer shell 13;

[0040] Reference Figure 1-Figure 6 Before attaching the light bar 19, turn on the suction pump 11 to suck air, allowing the suction holes 10 to suck air. Then, arrange the light bar 19 along the guide groove 9. At this time, the suction holes 12 suck the light bar 19, and the excess light bar 19 is arranged along the side wall of the attachment plate 4, making the light bar 19 contact the longitudinal side wall of the suction plate. Let the suction holes 12 adsorb the light bar 19, thus installing the entire light bar 19 on the suction plate; under the attachment of the light bar 19, drive the lifting assembly to lower the lifting plate 3, and then drive the first cylinder 5 to move the mounting plate 7 towards the side wall of the outer shell 13 with double-sided tape until the light bar 19 is attached to the outer shell 13. Then, control the suction pump 11 to stop sucking air, so that the suction holes 10 no longer adsorb the light bar 19, thereby fixing the light bar 19 on the outer shell 13. The process is fast and simple, achieving the effect of facilitating the attachment of the light bar 19.

[0041] Reference Figure 1-Figure 6 The suction holes 12 adsorb the excess light bar 19. When installing the light bar 19, it can reduce the contact between the excess light bar 19 and the side wall of the outer shell 13, thereby reducing the influence on the attachment of the light bar 19 and making the light bar 19 more stably attached to the transverse side wall of the outer shell 13; a rotary cylinder 15 is fixedly arranged on the attachment plate 4, and a protection plate 16 is fixedly arranged on the rotating head of the rotary cylinder 15. The protection plate 16 in this embodiment is relatively thin. After the light bar 19 is attached to the attachment plate 4, drive the rotary cylinder 15 to rotate the protection plate 16 towards the side of the excess light bar 19; when the attachment plate 4 moves downward, the protection plate 16 enters the outer shell 13. At this time, the outer shell 13 separates the excess light bar 19 from the outer shell 13, thereby avoiding excessive friction when the excess light bar 19 contacts the longitudinal side wall of the outer shell 13 during the attachment of the light bar 19, effectively reducing the damage of the excess light bar 19. It should be noted that the excess light bar 19 does not participate in the actual light emission work of the backlight module. Therefore, according to actual production needs, after the light bar 19 is attached to the transverse side wall of the outer shell 13, the excess light bar 19 can be cut off, or the excess light bar 19 can be placed at the bottom of the outer shell 13.

[0042] Reference Figure 1-Figure 6 A display screen 17 is fixedly arranged on the lifting plate 3, and the pressure sensor 8 is electrically connected to the display screen 17. When attaching the light bar 19, the pressure sensor 8 detects the pressure of the attachment plate 4 on the light bar 19. When the pressure is too large or too small, it indicates that the light bar 19 is not normally attached to the side wall of the outer shell 13, thereby determining whether the corresponding light bar 19 moves a specified distance and is attached to the side wall of the outer shell 13. Multiple pressure sensors 8 can improve the accuracy of detecting the attachment pressure.

[0043] Reference Figure 1-Figure 6, a pressure display gauge 18 is fixedly arranged on the air suction pipe 6. The pressure display gauge 18 in this embodiment is a digital pressure gauge. When the adsorption holes 10 and the air suction holes 12 adsorb the lamp strip 19, at this time, observe whether the value shown on the pressure display gauge 18 is within the specified pressure value range. If it is not within the specified pressure value range, it indicates that the lamp strip 19 is not properly attached to the adsorption plate at this time, reminding the staff to check and improving the accuracy during attachment;

[0044] Refer to Figure 1-Figure 6 , and in order to further check whether the lamp strip 19 is fully attached to the outer shell 13, after the lamp strip 19 is attached to the outer shell 13, at this time, the suction pump 11 reduces the suction intensity, so that the adsorption force of the adsorption holes 10 and the air suction holes 12 is less than the adhesion force of the lamp strip 19 on the outer shell 13, and then drive the first cylinder 5 to move the attachment plate 4 a short distance. At this time, observe whether the value on the pressure display gauge 18 is within the specified range (zero); if the value of the pressure display gauge 18 is not within the specified range, it indicates that part of the lamp strip 19 is not fully adsorbed on the outer shell 13, resulting in it moving together with the adsorption hole 10, thus immediately reminding the staff that the lamp strip 19 is not fully attached to the outer shell 13.

[0045] Refer to Figure 1-Figure 6 , a guide groove 9 is provided. When installing the lamp strip 19 on the attachment plate 4, it is convenient to align the lamp strip 19, reduce the movement of the lamp strip 19, and improve the accuracy during attachment; a guide block 20 is fixedly arranged on the attachment plate 4, and the guide block 20 is located above the guide groove 9. When installing the lamp strip 19, the guide block 20 conveniently guides the lamp strip 19 to be attached to the guide groove 9, facilitating the alignment by the staff.

[0046] Refer to Figure 1-Figure 6 , a second cylinder 21 is vertically and fixedly arranged on the side wall of the attachment plate 4. A stop block 22 is fixedly arranged on the telescopic shaft of the second cylinder 21, and the stop block 22 moves up and down along the side wall of the attachment plate 4. Before the lamp strip 19 is installed on the adsorption plate, at this time, drive the second cylinder 21 to move the stop block 22 downward, close to the guide groove 9. During attachment, make one end of the lamp strip 19 contact the stop block 22, and at the same time, the upper side of the lamp strip 19 contacts the groove wall of the guide groove 9, so as to align the lamp strip 19 and improve the accuracy of attaching the lamp strip 19, achieving the effect of facilitating the alignment of the lamp strip 19; after the lamp strip 19 is installed, drive the second cylinder 21 to move the stop block 22 upward to prepare for the next installation of the lamp strip 19.

[0047] Refer to Figure 1-Figure 6 , and at the same time, this device can also be used to attach double-sided tape. Just place the double-sided tape in the guide groove 9, drive the lifting assembly and the first cylinder 5 to make the adhesive surface of the double-sided tape attach to the outer shell 13. At this time, the release paper of the double-sided tape is adsorbed through the adsorption hole 10 to tear off the double-sided tape, completing the attachment of the double-sided tape, achieving the effect that both the double-sided tape and the lamp strip 19 can be attached.

[0048] The implementation principle of this embodiment is as follows: First, install the light bar 19 on the attachment plate 4, and let the air suction holes 12 and the adsorption holes 10 suck the light bar 19. Then, judge whether the light bar 19 is attached correctly according to the value of the pressure display meter 18. After the light bar 19 is attached to the attachment plate 4, drive the lifting assembly to move the light bar 19 downward into the housing 13, and then drive the first cylinder 5 to move the light bar 19 toward the lateral side wall of the housing 13 until the light bar 19 is attached to the housing 13. At this time, observe the display screen 17 and judge whether the light bar 19 is normally attached to the housing 13 according to the detection of the pressure sensor 8. After pasting, control the air suction pump 11 to stop pumping air, and let the air suction holes 12 and the adsorption holes 10 loosen, thus completing the installation of the light bar 19. The process is fast and simple, achieving the effect of facilitating the installation of the light bar 19.
