Description

Technical Field

[0001] The invention relates to the field of backlight module manufacturing, and in particular to a light bar preprocessing device for pre-pressing and pre-folding light bars. Background Art

[0002] At present, with the increasing use of display devices, manufacturers have higher and higher requirements for the yield rate in their production process. Display devices usually include backlight modules and display panels. In the backlight module, the light bar is particularly important. Generally, in the manufacturing process of the backlight module, the light bar needs to be pre-pressed and pre-folded. The pre-pressed and pre-folded auxiliary jigs currently used for light bars generally position the light bar through a positioning iron sheet, and then perform the pre-folding operation manually. In this process, the contact between the positioning iron sheet and the light bar can easily cause damage to the light bar. The pre-folding operation needs to be performed manually, which is cumbersome and has a low degree of automation. At the same time, the light bars of different models may have different shapes and sizes. If the pre-pressed and pre-folded operation is performed, the appropriate pre-pressed and pre-folded auxiliary jig needs to be re-made, and the manufacturing cost is relatively high.

[0022] Please refer to Figure 1 , Figure 2A , Figure 2B and Figure 3 , Figure 1 FIG. 1 is a top view of the light bar preprocessing device of the present invention. Figure 2A FIG. 1 is a schematic structural diagram of the pressing component of the positioning module of the present invention in the first position. Figure 2B FIG. 1 is a schematic structural diagram of the pressing component of the positioning module of the present invention in the second position. Figure 3 The figure shows the structure of the flip module of the light bar pre-processing device of the present invention. Figure 1 , Figure 2A , Figure 2B and Figure 3 As shown, the present invention provides a light bar preprocessing device 100, which includes a carrier 10, a positioning module 20 and a flip module 30; the carrier 10 is used to carry the light bar to be preprocessed, and the carrier 10 has a first groove 11, which adapts to the shape of the light bar; the positioning module 20 is located on one side of the carrier 10 and forms an angle with the carrier 10, and the positioning module 20 includes a first driving component 21, a lever component 22 (at Figure 1When the flip module 30 is located at the front side of the carrier 10, and the light bar is placed in the first groove 11, at least part of the light bar is located on the flip module 30, and the flip module 30 includes a third driving component 31 and a pressing plate 32, and the third driving component 31 is used to drive the pressing plate 32 to rotate relative to the carrier 10; when in use, in the initial state, there is a spacing between the positioning module 20 and the carrier 10, and the light bar is moved along the first groove 11. 1, at least part of the light bar is located on the flip module 30, the lever component is driven to move by the first driving component and the pressing component is driven to rotate by the first angle, the lever component 22 is driven to move by the first driving component 21 and the pressing component 23 is driven to rotate by the first angle A1, so that a clearance space is formed between the pressing component 23 and the carrier 10; then the second driving component 24 drives the first driving component 21, the lever component 22 and the pressing component 23 to move as a whole to approach the light bar, at this time, a part of the light bar is located in the clearance space of the pressing component 23, the first driving component 21 drives the pressing component 23 to rotate by the first angle A1 and abut the light bar; finally, the third driving component 31 drives the pressing plate 32 to rotate by the second angle A2 so that at least part of the light bar located on the flip module 30 is folded relative to the light bar located in the first groove 11, and the pre-treatment is completed.

[0023] like Figure 2A and Figure 2B As shown, in one embodiment, when the light bar pre-processing device 100 is in the initial state, the lever component 22 is in the retracted state, the pressing component 23 is in the first position, and the pressing component 23 is horizontally parallel to the carrier 10. At this time, the positioning module 20 is separated from the carrier 10 by a certain distance to prevent the operator from placing the light bar on the carrier 10 due to the influence of the positioning module 20. When the light bar pre-processing device 100 is in the working state, first, the first driving component 21 drives the lever component 22 to move from the retracted state to the extended state, and the lever component 22 drives the pressing component 23 When rotating from the first position to the second position, the pressing component 23 rotates by a first angle A1 relative to the carrier 10, and the first angle A1 is between 60° and 90°. That is to say, the pressing component 23 is tilted upward by a certain angle under the action of the lever component 22, and then the second driving component 24 drives the first driving component 21, the lever component 22 and the pressing component 23 to move toward the carrier 10 as a whole. During this process, the pressing component 23 always remains in a tilted state to avoid touching the light bar placed on the carrier 10 during the movement, thereby rubbing the light bar and causing damage to the light bar.

[0024] The light bar preprocessing device 100 of the present invention places the light bar in the first groove 11 on the carrier 10, and the pressing component 23 is driven by the lever component 22 to tilt upward and move close to the light bar. After reaching the preset position, the first driving component 21 drives the lever component 22 from a retracted state to an extended state and drives the pressing component 23 to rotate to the initial first position, that is, a position parallel to the carrier 10. At this time, the pressing component 23 just contacts the light bar to fix it on the carrier 10, and then the pressing plate 32 is driven to rotate by the third driving component 31, so that the light bar on the pressing plate 32 rotates a certain angle relative to the light bar fixed by the pressing component 23, thereby realizing the automatic pre-pressing and pre-folding processing of the light bar.

[0025] like Figure 1 As shown, in one embodiment, the positioning module 20 further includes a vertical plate 25, and the vertical plate 25 can form an extension portion toward the pressing component 23. The extension portion and the pressing component 23 are connected through a connecting portion to realize the rotation of the pressing component 23 relative to the column 25 (extension portion). The first driving component 21 and the second driving component 24 are located on one side of the vertical plate 25, and the lever component 22 and the pressing component 23 are located on the other side of the vertical plate 25. When the light strip preprocessing device 100 is in a working state, the second driving component 24 drives the vertical plate 25 to move until it abuts against the carrier 10. In actual applications, for example, the lever component 22 and the pressing component 23 are closer to the carrier 10 than the first driving component 21 and the second driving component 24, and the vertical plate 25 is connected to the second driving component 24 and can move relative to the carrier 10. During the driving process of the second driving component 24, the lever component 22, the pressing component 23, the first driving component 21 and the vertical plate 25 are moved as a whole to a preset position, that is, the vertical plate 25 contacts the carrier 10. For example, the side of the carrier 10 close to the positioning module 20 may also have a protrusion, which is adapted to the angle between the positioning module 20 and the carrier 10, so that during the movement of the positioning module 20, the protrusion can block the vertical plate 25 to prompt the positioning module 20 to move into place, thereby avoiding the positioning module 20 from moving out of place or moving excessively.

[0026] In one embodiment, the carrier 10 further includes a limiting groove 12. When the second driving component 24 drives the lever component 22, the pressing component 23, the first driving component 21 and the vertical plate 25 to move as a whole to a preset position, the first driving component 21 drives the pressing component 23 to rotate from the second position to the first position by the first angle A1. At this time, the pressing component 23 is just placed in the limiting groove 12. The pressing component 23 is limited by the limiting groove 12, and the rotation of the pressing component 23 is driven by the lever component 22. Since the movement of the lever component 22 is fixed, the rotation angle of the pressing component 23 can be fixed, thereby preventing the pressing component 23 from rotating out of place and failing to effectively fix the light bar or rotating excessively, resulting in excessive pressing force on the light bar and causing damage. The limiting groove 12 is connected to the first groove 11 at one end of the carrier 10 adjacent to the flip module 30, that is, the limiting groove 12 has the same depth as the first groove 11. When the pressing component 23 is located in the limiting groove 12, the pressing component 23 can just abut the light bar placed in the first groove 11. The limiting groove 12 and the first groove 11 form a third angle A3, that is, the pressing component 23 and the light bar form a third angle A3, and the third angle A3 is between 30° and 60°.

[0027] like Figure 1 and Figure 3 As shown, in one embodiment, the side of the pressing plate 32 close to the carrier 10 has a fourth angle A4 with the light bar, and the sum of the fourth angle A4 and the third angle A3 is 90°. In actual applications, the end of the pressing component 23 that contacts the light bar is approximately rectangular. When the pressing component 23 contacts the light bar, the contact line between the pressing component 23 and the light bar is nearly parallel to the side of the pressing plate 32 close to the carrier 10, so that during the rotation of the pressing plate 32, the light bar can be better folded. The sizes of the third angle A3 and the fourth angle A4 can be selected according to actual needs.

[0028] In one embodiment, the pressing plate 32 and the carrier 10 are located at the same height, and the pressing plate 32 has a second groove 321, and the second groove 321 adapts to the shape of the light bar. The line connecting the first groove 11 and the second groove 321 is a horizontal line. When the light bar is placed on the carrier 10, part of the light bar is placed in the first groove 11, and the remaining part of the light bar is placed in the second groove 321. The pressing plate 32 is rotated by a second angle A2 to fold the light bar. The second angle A2 is between 60° and 90°. Figure 3 As shown, in this embodiment, the second angle A2 is 90°. Figure 3 As shown, the dotted line represents the position of the pressing plate 32 when the light bar preprocessing device 100 is in the initial state, and the solid line represents the position of the pressing plate 32 when the light bar preprocessing device 100 is in the working state. At this time, the pressing plate 32 is rotated 90° relative to the initial position, so that the light bar can be folded into place.

[0029] In one embodiment, the light strip preprocessing device 100 further includes a workbench 40, the carrier 10 is arranged on the workbench 40, and a switching switch 41, a jog button 42 and an automatic button 43 are also provided on the workbench 40. The switching switch 41 is used to adjust the light strip preprocessing device 100 to work in the jog mode or in the automatic mode, so that the positioning module 20 and the flip module 30 are operated in the jog mode or the automatic mode. The operator selects the corresponding jog button 42 or the automatic button 43 according to the working mode of the light strip preprocessing device 100. When the operator switches the switch 41 to the automatic mode, the light bar preprocessing device 100 works in the automatic mode. After the operator places the light bar in the first groove 11 of the carrier 10 and the second groove 321 of the pressure plate 32, the operator presses the automatic button 43, and the positioning module and the flip module 30 are activated in sequence to automatically complete the pre-pressing and pre-folding processing operation of the light bar; when the operator switches the switch 41 to the inching mode, the light bar preprocessing device 100 works in the inching mode. After the operator places the light bar in the first groove 11 of the carrier 10 and the second groove 321 of the pressure plate 32, the operator presses the inching button 42 and keeps it pressed, the positioning module and the flip module 30 are activated in sequence. If the operator releases the inching button 42 during the actuation process, the light bar preprocessing device 100 stops operating immediately. This working mode is conducive to stopping the operation in time when an abnormal situation occurs during the pre-pressing and pre-folding operation of the light bar to avoid damage to the light bar.

[0030] In summary, the present invention provides a light bar preprocessing device. After placing the light bar in the groove on the carrier, the positioning module is started to move close to the light bar and the light bar is positioned through the pressing component. The pressing plate in the flipping module is driven to rotate so that the light bar is folded. In this way, the light bar preprocessing device is used to realize the automatic pre-pressing and pre-folding of the light bar, thereby improving production efficiency. Furthermore, the pressing component is driven by the lever component to rotate, so that the pressing component and the carrier form a clearance space to avoid the pressing component squeezing the light bar, and when the pressing component is rotated to abut the light bar, the force of the pressing component is controlled by the lever component to avoid damage to the light bar, thereby improving the production yield.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
