In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Taking a 23.8 inch frameless backlight source as an example, the reject ratio of the on-line production of the backlight source module is 3-8%, that is, when every 10000 backlight sources are on-line production, 300-800 rejected backlight source modules exist. If the backlight frames in the backlight module are discarded, a lot of resources are wasted, so it is important to clean the backlight frames for reuse.
Fig. 1 is a schematic structural diagram of a tool for cleaning a backlight frame according to an embodiment of the present invention. Referring to fig. 1, the tool for cleaning the backlight frame comprises a scraper 10 and a backlight frame mounting base 20, wherein the scraper 10 is slidably arranged on the backlight frame mounting base 20.
The scraper 10 is used for scraping the foam adhesive tape 301 on the backlight frame 30, and the backlight frame mounting base 20 is used for mounting the backlight frame 30.

As shown in FIG. 1, the tool for cleaning the backlight frame includes only one blade 10, and in other implementations, the tool for cleaning the backlight frame may include at least two blades 10.
Referring again to fig. 1, the backlight frame mount 20 has a backlight frame mount slot 21. The backlight frame mounting groove 21 is used for mounting the backlight frame 30, so that the backlight frame 30 is fixed on the backlight frame mounting base 20.
As shown in fig. 1, when the backlight frame 30 is mounted on the backlight frame mounting groove 21, the blade edge of the blade 10 contacts the foam tape 301 on the backlight frame 30, and the sliding direction c of the blade 10 coincides with the longitudinal direction of the foam tape 301 on the backlight frame 30.
When the tool for cleaning the backlight frame is used, the backlight frame 30 is placed in the backlight frame installation groove 21 of the backlight frame installation seat 20, so that the backlight frame 30 is fixed on the backlight frame installation seat 20, and the backlight frame 30 is prevented from moving in the working process; at this time, the knife edge of the scraper 10 contacts with the foam adhesive tape 301 on the backlight frame 30, and since the scraper 10 can slide on the backlight frame mounting seat 20, and the sliding direction c of the scraper 10 is the same as the length direction of the foam adhesive tape 301, the knife edge of the scraper 10 can scrape the foam adhesive tape 301 on the backlight frame 30 in the sliding process of the scraper 10, so as to remove the foam adhesive tape 301 on the backlight frame 30, and the backlight frame after removing the foam adhesive tape can be reused after being cleaned, thereby avoiding resource waste.

Referring to fig. 3, when the backlight frame 30 is placed in another backlight frame mounting groove 21 (i.e., the backlight frame mounting groove having a darker color in fig. 3), the second longitudinal direction b of the backlight frame mounting groove 21 is perpendicular to the sliding direction c of the blade 10. The blade edge of the scraper 10 contacts the short edge of the backlight frame 30, and the foam tape 301 on the short edge of the backlight frame 30 can be scraped up during the sliding process of the scraper 10.
When the backlight frames 30 are sequentially installed in the two backlight frame installation grooves 21, it can be ensured that any one side of the backlight frames 30 can be in contact with the knife edge of the scraper 10, and the scraper 10 can clean the foam adhesive tape 301 on the four sides of the backlight frames 30.
Referring again to fig. 1, the backlight frame mount 20 includes a base 202 having a boss 201 and a movable plate 203 detachably disposed on the base 202. The scraper 10 is located on the boss 201, a first part 21A of the backlight frame mounting groove 21 is formed between the movable plate 203 and the boss 201 of the base 202, a second part 21B of the backlight frame mounting groove 21 is formed on the movable plate 203, and the first part 21A and the second part 21B form a complete backlight frame mounting groove 21 for mounting the backlight frame 30.
The base 202 can fix the whole backlight frame mounting base 20, so that the stability of the backlight frame mounting base 20 in the working process is ensured; the movable plate 203 is used to fix the backlight frame 30 and prevent the backlight frame 30 from moving during operation.
The movable plate 203 is detachable, so when the tool for cleaning the backlight frame is used, the movable plates 203 with different sizes can be replaced according to the size of the backlight frame 30, so that the tool for cleaning the backlight frame can adapt to backlight frames 30 with more sizes, and the tool for cleaning the backlight frame has stronger applicability; meanwhile, the movable plate 203 is movable, and the size of the gap between the movable plate 203 and the boss 201 can be adjusted by adjusting the position of the movable plate 203, that is, the width of the backlight frame installation groove 21 can be adjusted, so that the width of the backlight frame installation groove 21 is enough to be placed in the backlight frame 30.
Fig. 4 is a schematic structural diagram of a movable plate according to an embodiment of the present invention. Referring to fig. 4, the movable plate 203 includes a movable main plate 231 and a restriction plate 232 detachably disposed on the movable main plate 231.

The degree of adhesion between the backlight frame 30 and the backlight frame mounting base 20 can be adjusted by the stopper bracket 221.
Referring again to fig. 5, the base 202 is provided with a threaded hole 202A. As shown in fig. 4, the movable plate 203 is provided with a through hole 203A, and the movable plate 203 further includes a bolt 203B. The bolt 203B penetrates through the through hole 203A and then is in threaded connection with the threaded hole 202A, the cross sections of the screw rods of the through hole 203A and the bolt 203B are both circular, and the diameter of the through hole 203A is larger than that of the screw rod of the bolt 203B. The movable plate 203 and the base 202 are connected by the bolt 203B, and the movable plate 203 is fixed on the base 202, so that the backlight frame 30 is prevented from moving during operation.
Because the diameter of the through hole 203A is greater than the diameter of the screw of the bolt 203B, after the movable plate 203 with the backlight frame 30 mounted thereon is placed on the base 202, the movable plate 203 and the base 202 can be connected together by the bolt 203B, and at this time, the bolt 203B does not need to be screwed, so that the movable plate 203 can be moved, the position of the movable plate 203 can be manually adjusted to adjust the width of the backlight frame mounting groove 21, so that the backlight frame 30 is attached to the side wall of the boss 201, and at this time, the bolt 203B is screwed again, so that the movable plate 203 is fixed on the base 202, and it can be ensured that the backlight frame 30 does not move in the working process.
Illustratively, the difference between the diameter of the through hole 203A and the diameter of the screw of the bolt 203B ranges from 4mm to 6 mm. Not only is the position of the movable plate 203 convenient to adjust, but also the problem that the diameter of the through hole 203A is too large to affect the strength of the whole movable plate 203 is avoided.
For example, the difference between the diameter of the through hole 203A and the diameter of the screw of the bolt 203B may be 5 mm.
Exemplarily, the movable plate 203 further includes a limit screw pad 203C, the bolt 203B firstly passes through the limit screw pad 203C, then passes through the through hole 203A, and then is in threaded connection with the threaded hole 202A, the limit screw pad 203C is circular ring-shaped, and the outer diameter of the limit screw pad 203C is greater than the diameter of the through hole 203A. The limit screw washer 203C is located between the movable plate 203 and the nut of the bolt 203B, and the limit screw washer 203C can be pressed against the movable plate 203 by screwing the bolt 203B, so that the movable plate 203 is pressed against the base 202, and the movable plate 203 is fixed, and the movable plate 203 does not move relative to the base 202 in the working process.
Illustratively, the difference between the outer diameter of the setscrew shim 203C and the diameter of the through hole 203A ranges between 4mm and 6 mm. The limiting screw gasket 203C can play a role in compressing, the movable plate 203 is fixed on the base 202, and the problem that the appearance of the limiting screw gasket 203C is influenced by the fact that the outer diameter of the limiting screw gasket 203C is too large than the diameter of the through hole 203A is solved.
For example, the difference between the outer diameter of the setscrew shim 203C and the diameter of the through hole 203A may be 5 mm.
Referring to fig. 4 again, the number of the through holes 203A, the bolts 203B and the limiting screw washers 203C on the movable plate 203 is 2, and the through holes, the bolts 203B and the limiting screw washers 203C are located at two opposite corners of the movable plate 203, so that the design can play a role in fixing, save parts and facilitate assembly. In other implementations, the number of the through holes 203A, the bolts 203B, and the limiting screw spacers 203C on the movable plate 203 may be more, and the positions may be set in other manners, but it is ensured that the number of the through holes 203A, the bolts 203B, and the limiting screw spacers 203C are equal, and the movable plate 203 can be fixed.
As shown in fig. 4, one of the two through holes 203A may be provided on the movable main plate 231, and the other may be provided on the first restriction plate 232A.

The sliding direction of the scraper 10 is guided by the sliding groove 121 and the sliding guide 222, and since the sliding guide 222 is arranged along one side of the base 202 and one side of the backlight frame is arranged along one side of the base 202, the sliding direction of the scraper 10 is ensured to be consistent with the direction of one side of the backlight frame, and the blade 101 can scrape the foam adhesive tape on the backlight frame during the sliding process of the scraper 10.
As shown in FIG. 1, the handle 103 is oriented perpendicular to the orientation of the slide rail 222, which is designed to further facilitate controlling the sliding of the taping knife 10. In other implementations, the orientation of the handle 103 is not limited.
As shown in fig. 4, the sliding guide 222 is fixed to the base 202 by screws, and this is designed to facilitate the detachment of the sliding guide 222. The sliding guide 222 may be secured in other ways in other implementations, such as by a snap.
Referring again to fig. 9, blade mount 102 includes a slider 122, a blade lower positioning plate 123, and a blade pressure plate 124. The lower blade positioning plate 123 is fixed on the slider 122, the side of the lower blade positioning plate 123 has an inclined surface 123A, the blade 101 is located between the inclined surface 123A and the blade pressing plate 124, and the bottom surface of the slider 122 has a sliding groove 121.
The blade lower positioning plate 123 is matched with the blade pressing plate 124, so that the blade 101 is prevented from moving in the direction vertical to the inclined plane 123A in the working process, and the stability of the blade 101 is ensured. The sliding groove 121 on the bottom surface of the slider 122 is engaged with the sliding guide 222 on the base 202 to guide the sliding direction of the entire scraper 10, so that the entire scraper 10 slides along the sliding guide 222.
As shown in fig. 9, the blade mount 102 further includes a blade guard 125, the side of the bevel 123A has a boss 123B, and the edge of the blade 101 faces the boss 123B. The blade guard 125 is located between the blade lower positioning plate 123 and the blade pressing plate 124, and the blade guard 125 cooperates with the boss 123B to prevent the blade 101 from moving in the inclined direction of the inclined surface 123A during operation.
Illustratively, the length of the boss 123B is less than the length of the knife edge of the blade 101. The knife edge of the blade 101 faces the boss 123B, so that the blade 101 can protrude out of the boss 123B, and the part of the blade protruding out of the boss 123B can scrape the foam adhesive tape on the backlight frame in use.
Illustratively, the distance between the boss 123B and the blade guard 125 in a direction parallel to the inclined surface 123A of the blade lower positioning plate 123 is greater than the width of the blade 101, i.e., there is a gap between the blade 101 and the blade guard 125 of the mounted doctor 10. Because the blade 101 may need to be replaced during use, the blade 101 can be easily removed when replacing the blade 101 because there is a gap between the blade 101 and the blade guard 125. And if the width of the replaced blade 101 is slightly increased, it is ensured that the replaced blade 101 can be installed between the boss 123B and the blade guard 125.
Illustratively, the difference between the distance between the boss 123B and the blade guard 125 and the width of the blade 101 ranges from 0.5mm to 1.5 mm. Ensure that when the width of the blade 101 is slightly increased, the blade 101 can still be installed between the boss 123B and the blade baffle 125, and simultaneously avoid the gap from being too large, the blade 101 moves in the inclined direction parallel to the inclined plane 123A during the operation, which is inconvenient to operate.
For example, the difference between the distance between the boss 123B and the blade guard 125 and the width of the blade 101 may be 1.0 mm.
As shown in fig. 9, the blade lower positioning plate 123 has two inclined surfaces 123A, two blades 101 are disposed on the scraper 10, the two blades 101 are respectively disposed on the two inclined surfaces 123A, and the cutting edges of the two blades 101 are disposed oppositely. When the spatula 10 slides to one side on the base 202, the blade 101 on that side can scrape the foam tape on the backlight frame. When the scraper 10 slides back and forth on the base 202, one blade 101 can always scrape the foam adhesive tape on the backlight frame, and the working efficiency is improved.
Referring to fig. 9 again, the blade mounting base 102 further includes a first positioning screw 126, the sliding block 122, the lower blade positioning plate 123, the blade retaining plate 125, the blade pressing plate 124 and the handle 103 have a first positioning screw hole 127 corresponding to each other, and the sliding block 122, the lower blade positioning plate 123, the blade retaining plate 125, the blade pressing plate 124 and the handle 103 are fixed by the first positioning screw 126 and the first positioning screw hole 127.
The sliding block 122, the lower blade positioning plate 123, the blade baffle 125, the blade pressing plate 124 and the handle 103 are fixed by the first positioning screw 126, so that when one structure of the scraper 10 is damaged, the scraper 10 can be disassembled by unscrewing the first positioning screw 126, and one structure of the scraper 10 can be replaced without replacing the whole scraper 10. In other implementations, the slider 122, the blade lower positioning plate 123, the blade stop 125, the blade press plate 124, and the handle 103 may be fixed by other means, such as welding, and the fixing is more secure by welding.
Referring to fig. 9 again, the slider 122, the lower blade positioning plate 123, the blade retaining plate 125, the blade pressing plate 124 and the handle 103 are all provided with 4 first positioning screw holes 127, so that the fixing effect of the first positioning screws 126 on the slider 122, the lower blade positioning plate 123, the blade retaining plate 125, the blade pressing plate 124 and the handle 103 can be enhanced. In other implementation manners, the number of the positioning blocks 122, the lower blade positioning plate 123, the blade retaining plate 125, the blade pressing plate 124 and the first positioning screw holes 127 on the handle 103 is not limited, and it is sufficient to ensure that the first positioning screws 126 and the first positioning screw holes 127 can fix the sliding blocks 122, the lower blade positioning plate 123, the blade retaining plate 125, the blade pressing plate 124 and the handle 103.
Referring again to FIG. 9, the angle α between the bevel 123A and the surface of the blade lower retaining plate 1231The obtuse angle, i.e. the angle between the blade 101 of the mounted spatula 10 and the surface of the backlight frame, makes it easier for the blade 101 of the spatula 10 to scrape the foam tape on the backlight frame.
Illustratively, the angle α between the bevel 123A and the surface of the blade lower retaining plate 1231Is in the range of 150 DEG to 170 DEG avoiding the included angle α1Too large, i.e. too small angle between blade 101 and the surface of the backlight frame, will not easily scrape the foam adhesive tape on the backlight frame, and avoid angle α1Too small, i.e. the angle of the blade 101 to the surface of the backlight frameToo great a force results in too great a friction between blade 101 and the surface of the backlight frame to slide doctor blade 10. for example, included angle α1May be 160.
Fig. 10 is a schematic diagram illustrating the operation of a doctor blade according to an embodiment of the present invention. Referring to fig. 10, in operation, when the blade 10 slides in the direction c, the lower edge surface of the blade 101 of the blade 10 is adjacent to and parallel to the backlight frame 30, and the edge of the blade 101 contacts the foam tape 301, separating the foam tape 301 by the edge upper surface.
