Description

494〇56, the scope of the invention description (1). The present invention relates to a V-cutting knife, a V-cutting knife tool kit for the manufacture of a light source panel for a liquid crystal display (Lcd) North :: J: : The work tool pin is used to form a V-shaped groove in the required part of the light source panel. BACKGROUND OF THE INVENTION When LCD is used as a display, because it does not send itself, a separate backlight unit is set behind the display. As a light source. 'So it is necessary now that all countries in the world have invested a lot in Maoyang industry, including Baoguo and Taiwan, and in order to meet the demand for LCD, in addition to ^ two books, Korean, and Kezhu, Gan / 1 related zero The components also increase the demand relatively. / At present, the LCD module has a lighter weight and a smaller volume, and the dimming group will change to a thin and light edge light mode. ° 'So why is the back light group adopted? The “edge light mode” is to make the light source panel pass side by side so that the brightness of the light source panel is more uniform. Thus, the bottom of the two light forms ordinary light. Since the transmitted light source of the first source panel is installed on the side of the light source panel, The greater the distance of the near light, the farther away from the light source, The smaller the distance, the more uniform the brightness. In order to keep the source panel < 1 the shape of the bottom of the conventional light source panel, the TFT_LCD is known as the Groove pattern type, and the notebook is 9 ^ printed For the computer and the screen, Figure 1_ is a longitudinal view of the edge light group of the trough light source panel, the top panel of the secondary crystal display light source panel, and the bottom is the bottom of the light source panel:

V. Description of the invention (2): = 11 side is coated with transmission material and is equipped with LCD, the light source panel m has many v-grooves, so that the front line from the light source panel-side is evenly distributed, and there is a reflection on it seat. The slot 3 on the Λ source surface Λ is emitted by the light source on the light source panel with 纟 dispersion: it is within the range of the projected light, so the slots and grooves around the light source 2 are so; but: the slots closer to the light source 2 and The distance between the grooves is small, so that the brightness of the light source panel 1 is kept uniform. The angle of the light: i: ancient 5 3: 2 The light emitted is not direct shot 'but is preset = / 二 The light is scattered on the inner surface of the panel, so the light hitting the old surface of the LCD is scattered on the upper surface of the light source panel. The light from the light source 2 is radiated by a central device, which is called a ^ -shaped cutter placed in the groove 3 STEPP0T0 to continuously drive-the sliding sheet forms a v-shaped groove on the light source panel. -Easy installation of the needle § The light source panel that already has a V-shaped groove is moved by the rail, and the control device pushes the sliding piece to the bottom = two moving r slides. This forms a V-shaped groove. 70% ^ 1 slot. After the above V-shaped groove is formed, the operation of repeatedly moving the tabletop into the v-shaped groove is repeated, so the light source panel forms a section of V-shaped. p (PITCH) conventionally forms the grooves on the light source panel in one row ', so it is extremely time-consuming and therefore costly. One by one, the sliding group moves back and forth on the guide rails, and the table moves a V-shaped groove on the source panel. The table must be p 1 during operation. The shoulder changes position to make the light source panel.

V. Description of the invention (3) The phase difference is as high as 90 degrees in order to escape the groove. τ described operations. As a result, it took a long time to complete the groove on the panel, which was short. Because the traditional root needles used to repeatedly operate each linen and hemp are used to form a V-shaped fruit, the device will be worn. Staff, the service life is changed. Solve the μ tool pin in the light source panel :: use: the lack of equipment 'simultaneously use several articles of the present invention! Ν-shaped grooves are formed on the position. To improve the operating efficiency is to provide a kind of needle that can be quickly changed and repaired, and the present invention is to change the pitch of the V-shaped groove uniformly by using an elastic body to hold each working needle t # 于 ^ ^ Is the same degree control screw on the balance board, # 4_ ,, 爻 Apply the load on the female needle. Ma Weicheng formed the tool groove of the above-mentioned groove of the present invention. He tried to find out that there is not a form of V and it is clamped and fixed. J = = there is a fixed piece on the sliding piece, and the piece is fixed to the fixed M, the buffer plate. Installed in the fixed position, the guide = Μ and insert people-magnets and the solid elastomer at the bottom. The insertion hole on the plate can be equipped with many tool pins for connection elasticity. The present invention will be described in detail with the following drawings: Fig. 1 is a longitudinal part of a groove on a backlight unit of a light source panel according to the present invention.

In the content of the present invention, the lifting device mounted on the control device 8 of the sliding group 6 moves horizontally along the track 5 (as shown in FIG. 2), and the buffer plate 10 is engaged with the lifting / lowering and is inserted with a plurality of magnets 9. The elastic body 11 is exposed from the side of the buffer plate 10 and fixed. The elastomer 11 is preferably composed of two or more substances. The elastomer of the lower layer is composed of a harder substance, and the upper layer is made of a softer substance.

494056 V. Description of the invention (6) These structures are designed to absorb the impact force on the tool needle 12 when the v-shaped groove on the light source panel 1 is formed, so that the load on the tool needle 12 can be evenly distributed, thereby extending its load. Service life. The guide plate 14 is installed at the bottom of the buffer plate 10. The guide plate 14 is provided with a through-hole 15 at a position π relative to the elastic body for inserting the tool needle 12 forming the v-shaped groove 3. Therefore, the top of the tool needle 12 can be connected to the elastic body 11. contact. Except that the tool needle 12 inserted into the through hole 15 is impacted, otherwise the tool needle 12 is constantly inserted into the through hole 15 of the guide plate 14 because of the magnetic force of the magnet of the buffer plate 10. In order to guide the guide plate 14 to be correctly attached to the bottom of the buffer plate 10, the contact surfaces of the two are at least two dowels (JoG GLESM6 are aligned with the positioning holes and fixed. When the guide plate 14 is located on the buffer plate 1 After the bottom of the 〇, the dowel pin 16 enters the positioning hole 17 and the contact surface is abutted to complete the tool package. 8. A buffer plate 10 and a guide plate 14 may directly contact the lifting block 7, but the lifting block 7 is fixed to The jaw clip 20a is preferably connected to the fixing piece 19 of the holder 20, which is used to support the buffer plate 10 and the guide plate 14 (see FIG. 2). ^ The fixing piece 19 and the holder 20 may It engages with the joining piece 21, but it is better to insert a rubber pad 22 between the fixing piece 19 and the holder 20 to improve its stability. The fixing piece 19 and the holder 20 each form a recess 23a, 23b, and a positioning key 24 determines the position of the holder 20. The rice buffer plate 10 and the guide plate 14 are mounted on the fixed piece 19 and the holder 20-2, and the magnets 25 and 26 are inserted into the fixed piece 19 and the holder 20. At the bottom, the magnet 9 is inserted into the buffer plate 10 to support the buffer plate 1 between the fixing piece 19 and the holder 20.

494056 V. Description of the invention (7) and guide plate 14 without the need for additional fixing devices. The magnetic force of the magnets 9, 25, 26 between the buffer plate 10, the guide plate 1, the fixing piece 19, and the holder 20. It is about 2, 500-3, 500 gauss. The above magnetic force is used to prevent the plate from falling off due to the impact during work and the working needle in the through hole 15 of the guide plate 14 is detached from the through hole. The magnetic force of the magnet 9 is only It is enough to keep the working needle 丨 2 in the through hole 15 under static conditions, but it can be separated only when the damaged working needle needs to be replaced. According to the difference in the spacing between the v-grooves on the light source panel 1, the working needle changes accordingly. Several height control bolts 27 are used to adjust the angle of the buffer plate 10 so that the guide plate 14 and the holder 20 are properly engaged. 〇β Because the working needle 12 with a small pitch is given more than the working needle with a large distance 丨 2, the load of the sex body 1 1 is larger, and the length of the fine needle used for the small pitch is about 〇 · J 耄 m (mm) to Force (load) uniformly forming the v-shaped groove of the light source panel 1 Test 27 Ϊ Ϊ Ϊ Ϊ When the height of the gripper engagement on the small-pitch working needle 12 is controlled ΓϋΛ ', the magnet that fixes the buffer plate 10 to the clamp ㈣: :: force reduction 'generates an angle suitable for the working needle 12 (see the figure of the iron slanted source panel 1 to maintain uniform force, so the work output can be extended: π, and uniformly formed on the light source panel 1 The depth control bolt 27 of the V-shaped groove 3 can expose the clamper 20, but it is better to lock the bolt 28 on the clamper 2 () and the screw inspection 27__.) Plate 29 The control bolt 27 is turned around depending on the distance between the source panel 1 ± ν groove 3 to control the exposed length of the working needle 12, and the lock plate 2 can prevent the

4 ^ 403 () V. Description of the invention (8) The intended exposure of the working needle 12 is long and the m 1 can be changed at will by external force. a Because the V-groove on the light source panel is formed, if the work ^ 15 inserted into the guide plate 14 is opposite, the working needle 12 = must be matched. When thick, the through hole ^ ^ on the guide plate 14 changes its diameter. Conversely, if the diameter of the smaller-diameter hole 15 is to be inserted into the guide plate 14 with the working needles 12 and 12, the guide plate 14 can be composed of several thin plates for proper adjustment with ^. However, ‘such a straightness is more desirable. Compared with the conventional technology, the present invention is used to ensure the through-holes in the guide plate 14. First, a value at the bottom of the lifting block is seen. The number of V-shaped grooves of the panel 1 and the number of v-shaped pins are equal to the light source, which can reduce the reciprocating motion of the light source surface, such as the tabletop or sliding group. Imagine that there are costs in the side and in the vertical direction. In the middle of the table movement, the light source panel with a gutter-shaped groove is slid. In the present invention, whether it is a table or a shower, it corresponds to 500 slides. But in this time, the V-shaped groove can be completed, that is, the reciprocating motion can be performed once or two times each time. The working needle can be inserted into the guide tube 250 times more efficiently. The magnetic force of the magnet is maintained. If there is a perforation in the shell, and the damaged working needle inserted in the buffer plate is taken out from the guide plate and replaced with a new one, the damaged needle can easily be damaged. By using the control bolt, the pitch of the needles can be different to withstand the service life of different long working needles; the load of the working needles can therefore extend the groove. ^ V-shape with uniform-depth can be made
