Description

Technical Field

[0001] This application relates to the technical field of light guide plate processing, and in particular to a nickel plate electroplating forming tank for a light guide plate. Background Art

[0002] A light guide plate is an optical element used to convert a point light source or a line light source into a uniform surface light source. Its surface is usually designed with tiny concave points or dot patterns to achieve uniform light diffusion, and it is widely used in fields such as liquid crystal display (LCD) backlight modules and lighting devices.

[0003] Among them, the concave point or dot pattern structure on the surface of the light guide plate is usually formed by hot pressing. However, due to poor uniformity, the traditional hot pressing plate is likely to cause uneven concave point or dot pattern structure on the surface of the light guide plate, thereby affecting its optical performance. In recent years, with the rapid development of display technology, the accuracy requirements for the surface structure of the light guide plate have become higher and higher, and the traditional hot pressing plate has been difficult to meet the requirements of high precision and high uniformity.

[0004] Currently, the hot pressing parts for the surface hot pressing of light guide plates are usually nickel plates. Common nickel plate preparation technologies mostly use mechanical processing or chemical deposition methods, but these methods have problems such as high cost, low efficiency, and insufficient uniformity, which limit their application in the hot pressing treatment of light guide plates. Summary of the Invention

[0007] By adopting the above technical solution, the nickel precipitated after the electrolytic component electrolyzes the plating solution can flow with the plating solution through the mesh of the stencil to the surface of the light guide plate, so that the nickel can be evenly adsorbed on the concave points of the light guide plate to form a nickel plate of a certain thickness. After that, the nickel plate is peeled off from the light guide plate to obtain a hot-pressed part with better hot pressing effect; the preparation quality of the nickel plate is effectively improved, the cost is reduced and the efficiency is improved, thereby effectively improving the uniformity of the concave points or points obtained after the hot pressing treatment of the light guide plate, so as to ensure the optical performance of the light guide plate.

In this embodiment, since the electrolysis component 21 with the above functions is the prior art in this field, it will not be elaborated here, and it is only briefly shown in the drawings.

[0035] The clamping assembly 22 is detachably connected to the cell body 1 and is installed at a position of the cell body 1 away from the electrolysis assembly 21; the light guide plate 5 is also detachably connected to the clamping assembly 22. When the light guide plate 5 is clamped by the clamping assembly 22 and the clamping assembly 22 is connected to the cell body 1, the surface of the light guide plate 5 with the concave dot structure is in a vertical state and faces the electrolysis assembly 21, facilitating the nickel adsorbed after the electrolysis of the plating solution by the electrolysis assembly 21 to obtain a nickel plate. In this embodiment, it is preferably that the clamping assembly 22 is detachably connected to the cell body 1 through screws, and preferably the clamping assembly 22 clamps and positions light guide plates 5 of different sizes through two relatively slidable clamping pieces to achieve detachable connection; since the clamping assembly 22 with the above functions is a common prior art, it will not be elaborated herein, and it is only briefly shown in the drawings.

In this embodiment, since the above light guide plate 5 is a prior art in the art, it will not be elaborated herein, and it is only briefly shown in the drawings.

[0037] The auxiliary device 3 includes a mesh plate 31. The mesh plate 31 is an overall rectangular plate structure and is installed in the plating tank 11 in a state where its length direction is vertical, and it divides the plating tank 11 into two spaces; the mesh plate 31 is located between the electrolysis assembly 21 and the clamping assembly 22, so that the nickel obtained by electrolyzing the plating solution by the electrolysis assembly 21 needs to pass through the mesh plate 31 before being adsorbed on the surface of the light guide plate 5 with the concave dot structure. In this embodiment, it is preferably that the mesh plate 31 is detachably connected to the cell body 1, and the mesh plate 31 and the cell body 1 are detachably connected by means of plug-in fit; and preferably after the mesh plate 31 is connected to the cell body 1, the mesh plate 31 is centered in the plating tank 11 along the length direction of the plating tank 11, both sides in the width direction of the mesh plate 31 are in contact and abutted against the side walls on both sides of the plating tank 11, the top of the mesh plate 31 is exposed above the plating solution, and the bottom of the mesh plate 31 is in contact and abutted against the bottom wall of the plating tank 11.

The plurality of mesh holes 311 are evenly distributed on the mesh plate 31, and the mesh holes 311 communicate the spaces on both sides of the electroplating tank 11 with the mesh plate 31, facilitating the nickel obtained by the electrolysis assembly 21 from the electroplating solution to flow through the mesh holes 311 with the electroplating solution and adsorb on the surface of the light guide plate 5 having a concave dot structure.

[0039] Further, preferably, the plurality of mesh holes 311 on the mesh plate 31 are aligned one by one with the plurality of points of the concave dot structure on the light guide plate 5 along the length direction of the tank body 1, facilitating the nickel to flow through the mesh plate 31 with the electroplating solution and adsorb and fill on the surface of the light guide plate 5 to improve the quality of the nickel plate forming. In this embodiment, preferably, the mesh plate 31 has different specifications according to the distribution law and size of the mesh holes 311, and the staff can select a matching mesh plate 31 according to the concave dot structure on the light guide plate 5 for use.

[0040] The stirring device 4 includes a lifting assembly 41, a plurality of flow-pushing assemblies 42, and a plurality of disturbing assemblies 43. Among them, the lifting assembly 41 is used to control the positions of the flow-pushing assembly 42 and the disturbing assembly 43 in the electroplating tank 11; the flow-pushing assembly 42 is used to drive the electroplating solution to flow through the mesh plate 31, which helps the nickel to flow to the light guide plate 5 with the electroplating solution; the disturbing assembly 43 is used to disturb the electroplating solution to improve the uniformity of the electroplating solution and at the same time reduce the probability of nickel adhering to the tank wall of the electroplating tank 11.

[0041] The lifting assembly 41 includes a lifting frame 411 and a driving member 412, and a frame structure for installing the lifting assembly 41 is provided at the top of the middle position of the tank body 1 along its own length direction. The driving member 412 is fixedly installed at the top of the frame structure, the lifting frame 411 is installed below the frame structure, and the driving member 412 is used to drive the lifting frame 411 to move relative to the tank body 1 in the vertical direction. In this embodiment, preferably, the driving member 412 is a servo cylinder, and the lifting frame 411 remains above the electroplating solution during the moving process; since the servo cylinder is a common existing technology, it will not be elaborated here, and it is only briefly shown in the drawings.

[0042] Refer to Figure 1 and Figure 3 , the flow-pushing assembly 42 is installed at the bottom of the lifting frame 411 and on the side of the electrolytic rod 212 away from the mesh plate 31. In this embodiment, preferably, the stirring device 4 includes a total of two flow-pushing assemblies 42, and the two flow-pushing assemblies 42 are symmetrically distributed with respect to the tank body 1.

[0043] Refer to Figure 2 1]and Figure 3 , the flow-pushing assembly 42 includes a seat body 421, a driving blade 422, a plurality of flow-pushing blades 423, and a driving structure 424.

[0044] The top of the seat body 421 is fixedly connected to the bottom of the lifting frame 411. The bottom of the seat body 421 is immersed in the electroplating solution, and during the movement of the lifting frame 411, the bottom of the seat body 421 remains immersed in the electroplating solution.

[0045] The driving blade 422 is integrally in a rectangular sheet-like structure. One end in its length direction is rotatably connected to the bottom of the seat body 421, and the axis line of its rotating shaft 4241 is parallel to its width direction and parallel to the length direction of the tank body 1.

[0046] There are limitations during the rotation of the driving blade 422 relative to the seat body 421. During the upward and downward movement of the lifting member, the driving blade 422 rotates upward to the limit position under the action of the resistance of the electroplating solution. At this time, the length direction of the driving blade 422 is in an inclined state and the end away from the bottom of the seat body 421 is the inclined upper end; during the upward movement of the lifting member from bottom to top, the driving blade 422 rotates downward to the limit position under the action of the resistance of the electroplating solution. At this time, the length direction of the driving blade 422 is in an inclined state and the end away from the bottom of the seat body 421 is the inclined lower end. In this embodiment, it is preferably that during the rotation of the driving blade 422 relative to the seat body 421, it remains on the side of the bottom of the seat body 421 close to the other flow-pushing assembly 42.

[0047] The flow-pushing blade 423 is integrally in a rectangular sheet-like structure. One end in its length direction is rotatably connected to the bottom of the seat body 421. The axis line of its rotating shaft 4241 coincides with the axis line of the rotating shaft 4241 of the corresponding driving blade 422, and its width direction is inclined relative to the axis line of its rotating shaft 4241. At this time, during the rotation of the flow-pushing blade 423 relative to the seat body 421 in a certain direction, it can drive the electroplating solution around the flow-pushing blade 423 to flow in the direction parallel to the length direction of the tank body 1 towards the direction close to the mesh plate 31.

[0048] A plurality of flow-pushing blades 423 are all located on the side of the corresponding driving blade 422 close to the mesh plate 31 and are equidistantly distributed along the length direction of the tank body 1 at the bottom of the seat body 421. In this embodiment, it is preferably that the flow-pushing assembly 42 altogether includes three flow-pushing blades 423.

[0049] Refer to Figure 3 and Figure 4 , further, to improve the effect that the flow-pushing assembly 42 drives the nickel obtained by electrolyzing the electroplating solution by the electrolysis assembly 21 to flow through the mesh plate 31 along with the electroplating solution, it is preferably that two flow-pushing assemblies 42 are aligned with the space around a plurality of electrolysis rods 212 along the length direction of the tank body 1.

[0050] The driving structure 424 is installed inside the seat body 421 to form a linkage between the driving blade 422 and a plurality of flow-pushing blades 423, so that during the rotation of the driving blade 422 relative to the seat body 421, it can drive a plurality of flow-pushing blades 423 to rotate relative to the seat body 421.

[0051] The driving structure 424 includes a rotating shaft 4241, and a plurality of corresponding rotating seats 4242 and a plurality of synchronous belts 4243. In this embodiment, preferably, the driving structure 424 includes a total of four rotating seats 4242 and four synchronous belts 4243. The four rotating seats 4242 and the four synchronous belts 4243 correspond to the driving blade 422 and the three flow-pushing blades 423 one by one. The rotating seat 4242 is rotatably connected to the seat body 421, and both the driving blade 422 and the flow-pushing blades 423 are rotatably connected to the seat body 421 through the rotating seat 4242, that is, the axis line of the rotating shaft 4241 of the rotating seat 4242 coincides with the axis line of the rotating shaft 4241 of the corresponding driving blade 422 or the axis line of the rotating shaft 4241 of the flow-pushing blade 423.

[0052] The rotating shaft 4241 is integrally in a cylindrical structure. It is rotatably installed inside the seat body 421 and above the driving blade 422 and the flow-pushing blades 423. Its axis line of the rotating shaft 4241 coincides with its own axis and is parallel to the axis line of the rotating shaft 4241 of the driving blade 422. There are four annular convex structures extending radially outward on the rotating shaft 4241, and the four annular convex structures correspond to the four rotating seats 4242 one by one in the vertical direction.

[0053] The synchronous belt 4243 is simultaneously wound around and installed on the corresponding rotating seat 4242 and the corresponding annular convex structure on the rotating shaft 4241. At this time, when the driving blade 422 rotates relative to the seat body 421 under the resistance of the electroplating solution and drives the corresponding rotating seat 4242 to rotate relative to the seat body 421, it can drive the rotating shaft 4241 to rotate relative to the seat body 421 through the corresponding synchronous belt 4243, and then drive the three flow-pushing blades 423 and the other three rotating seats 4242 to rotate relative to the seat body 421 through the other three synchronous belts 4243. In this embodiment, since the driving structure 424 with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0054] Furthermore, preferably, the three flow-pushing blades 423 and the corresponding rotating seats 4242 are all unidirectionally rotatably connected, that is, the rotating seat 4242 can drive the corresponding flow-pushing blade 423 to rotate relative to the seat body 421 only when it rotates relative to the seat body 421 in a certain direction, driving the surrounding electroplating solution to flow towards the direction close to the mesh plate 31.

[0055] Refer to Figure 2 and Figure 3, in this embodiment, preferably, during the upward movement of the lifting frame 411, the driving blade 422 rotates relative to the seat body 421 under the resistance of the electroplating solution, and then can drive the three flow-pushing blades 423 to rotate relative to the seat body 421 through the driving structure 424, and the rotation directions of the three flow-pushing blades 423 are the same as the rotation direction of the driving blade 422; during the downward movement of the lifting frame 411, the driving blade 422 rotates relative to the seat body 421 under the resistance of the electroplating solution, and can only drive the three rotating seats 4242 corresponding to the three flow-pushing blades 423 to rotate relative to the seat body 421 through the driving structure 424. In this embodiment, since the one-way rotation connection method with the above functions is a common prior art (such as a ratchet and pawl structure), it will not be elaborated here, and its structure is omitted in the drawings.

[0056] Furthermore, to improve the flow-pushing effect of the flow-pushing assembly 42, it is preferred that the driving effects on different flow-pushing blades 423 by the driving assembly are different, and among the three flow-pushing blades 423, the driving effects towards the direction away from the driving blade 422 increase one by one.

[0057] During the upward movement of the lifting frame 411, when the driving blade 422 rotates from one extreme position to another extreme position relative to the seat body 421, it will drive the closest flow-pushing blade 423 to rotate at least one week through the driving structure 424, and the rotation angles of the three flow-pushing blades 423 increase one by one towards the direction away from the driving blade 422 during this process. In this embodiment, it is preferred that the driving structure 424 realizes the above functions by adjusting the radial dimensions of the three annular protrusion structures corresponding to the three flow-pushing blades 423 on the rotating shaft 4241, and the radial dimensions of the corresponding three annular protrusion structures increase one by one towards the direction away from the annular protrusion structure corresponding to the driving blade 422.

[0058] At this time, when the three flow-pushing blades 423 rotate relative to the seat body 421 to produce a flow-pushing effect on the electroplating solution, the flow rate of the electroplating solution under the flow-pushing effect can be gradually increased, and at the same time, the three differentially rotating flow-pushing blades 423 can improve the uniformity of the electroplating solution around them.

[0059] Refer to Figure 3 and Figure 4 , further, to reduce the probability that the flow-pushing blade 423 rotates relative to the seat body 421 to produce a reverse flow-pushing effect on the electroplating solution during the downward movement of the lifting frame 411, and at the same time reduce the resistance of the electroplating solution on the flow-pushing blade 423 during the process of the flow-pushing blade 423 rotating to produce a positive flow-pushing effect, it is preferred that a plurality of relief holes 4231 are formed in the flow-pushing blade 423 along the direction perpendicular to the line of its rotating shaft 4241 and perpendicular to its length direction, and the plurality of relief holes 4231 are evenly distributed on the flow-pushing blade 423, and the electroplating solution can pass through the relief holes 4231 to pass through the flow-pushing blade 423.

[0060] Reference Figure 1 and Figure 2 As shown in FIGS. and, a plurality of disturbance components 43 are also installed at the bottom of the lifting frame 411. The plurality of disturbance components 43 are distributed on both sides of the mesh plate 31 and are located between the electrolysis component 21 and the clamping component 22. During the up and down movement of the disturbance component 43 along with the lifting frame 411, it will move at positions close to the side walls and the bottom wall of the electroplating tank 11 on both sides of itself, so as to reduce the influence on the process of nickel flowing through the mesh plate 31 along with the electroplating solution during the disturbance of the electroplating solution by the disturbance component 43. In this embodiment, preferably, the stirring device 4 includes a total of four disturbance components 43. Two disturbance components 43 are distributed on each side of the mesh plate 31, and the two disturbance components 43 on the same side of the mesh plate 31 are respectively close to both sides in the width direction of the electroplating tank 11 and are symmetrically distributed.

[0061] Reference Figure 5 and Figure 6 As shown in FIGS. and, the disturbance component 43 includes a body 431, a movable part 432, a rotating rod 433, a disturbing part 434, an elastic part 435, a floating part 436 and a linkage structure 437.

[0062] Reference Figure 2 and Figure 5 As shown in FIGS. and, the bottom of the body 431 is fixedly connected to the bottom of the lifting frame 411, and its bottom is immersed in the electroplating solution. During the up and down movement of the body 431 along with the lifting frame 411, its bottom remains immersed in the electroplating solution.

[0063] Reference Figure 5 and Figure 6 As shown in FIGS. and, the movable part 432 is movably connected to the body 431, and its moving direction is parallel to the moving direction of the lifting frame 411; one end of the rotating rod 433 is rotatably connected to the movable part 432, and the axis line of its rotating shaft 4241 is parallel to the length direction of the tank body 1.

[0064] The disturbing part 434 is integrally in a cylindrical structure. It is rotatably connected to the end of the rotating rod 433 far from the movable part 432. The axis line of its rotating shaft 4241 coincides with its own axis and is parallel to the axis line of the rotating shaft 4241 of the rotating rod 433; the outer side of the disturbing part 434 is elastic and has a plurality of disturbing strips extending radially outward. And the disturbing part 434 can contact and abut against the side wall and the bottom wall of the electroplating tank 11 through the disturbing strips. When the disturbing strips of the disturbing part 434 contact and abut against the wall of the electroplating tank 11, it can effectively disturb the nickel attached to the wall of the electroplating tank 11 and improve the utilization rate of the adsorption of nickel on the surface of the light guide plate 5.

[0065] The elastic member 435 is installed at the rotational connection position between the rotating rod 433 and the movable member 432. Its two ends are respectively fixedly connected to the rotating rod 433 and the movable member 432, and it has a tendency to drive the rotating rod 433 to rotate downward to the limit position and stay there. In this embodiment, preferably, the elastic member 435 is a torsion spring, and preferably, when the rotating rod 433 rotates downward to the limit position, the length direction of the rotating rod 433 is parallel to the height direction of the cell body 1. Since the torsion spring is a common prior art, it will not be elaborated here, and only the installation position of the elastic member 435 is shown in the drawings and its structure is omitted from the expression.

[0066] The floating member 436 is movably installed on the body 431. Its moving direction is parallel to the moving direction of the movable member 432, and it has a tendency to float on the liquid surface of the electroplating solution. In this embodiment, preferably, the installation position of the floating member 436 on the body 431 is located on the side of the corresponding movable member 432 close to the side wall of the adjacent electroplating tank 11.

[0067] The linkage structure 437 is installed inside the body 431 to form a linkage between the floating member 436 and the corresponding movable member 432. During the process of the floating member 436 moving relative to the body 431, it can drive the movable member 432 to move in the opposite direction relative to the body 431 through the linkage structure 437.

[0068] The linkage structure 437 includes a first rack 4371, a second rack 4372, and a linkage gear 4373.

[0069] The first rack 4371 is fixedly installed on the floating member 436. Its extending direction is parallel to the moving direction of the floating member 436, and it is located on the side of the floating member 436 close to the corresponding movable member 432. The second rack 4372 is fixedly installed on the movable member 432. Its extending direction is parallel to the moving direction of the movable member 432, and it is located on the side of the movable member 432 close to the corresponding floating member 436. The linkage gear 4373 is rotatably installed inside the body 431 and is located between the first rack 4371 and the second rack 4372. Its rotation axis 4241 line is parallel to the rotation axis 4241 line of the rotating rod 433, and it meshes with both the first rack 4371 and the second rack 4372 simultaneously.

[0070] Refer to Figure 2 and Figure 6 During the process of the floating member 436 moving relative to the body 431, there are limitations. During the process of the lifting frame 411 moving, the floating member 436 will remain in the state of being immersed in the electroplating solution, and the first rack 4371 and the second rack 4372 will remain meshed with the linkage gear 4373 during this process.

[0071] Refer to Figure 2 and Figure 5, when the lifting frame 411 moves upward to the extreme position, the floating member 436 is in the state of moving downward to the extreme position relative to the body 431. At this time, the corresponding moving member 432 is in the state of moving upward to the extreme position, and at this time, the activity rod is in the position state where the length direction is parallel to the height direction of the cell body 1. The disturbing member 434 is in the position state where it is in contact with and abuts against the side wall of the electroplating tank 11 and there is a gap between it and the bottom wall of the electroplating tank 11.

[0072] Refer to Figure 2 and Figure 7 , after that, during the process of the lifting frame 411 moving downward, the disturbing member 434 will, in the state of being in contact with and abutting against the side wall of the electroplating tank 11, on the one hand, move downward with the body 431, and on the other hand, the floating member 436 moves upward relative to the body 431 under the buoyancy force of the electroplating solution and drives it to move downward through the linkage structure 437, improving the disturbing effect of the disturbing member 434 on the nickel adhering to the side wall of the electroplating tank 11; during this process, the disturbing member 434 will also rotate relative to the rotating rod 433, thereby improving its disturbing effect on the surrounding electroplating solution and further improving the uniformity of the electroplating solution.

[0073] After that, during the process of the lifting frame 411 moving downward until the disturbing member 434 contacts the bottom wall of the electroplating tank 11 and then continues to move downward to the extreme position, the acting force received by the disturbing member 434 will drive the rotating rod 433 to rotate relative to the moving member 432 against the acting force of the elastic member 435, so that the disturbing member 434 can move in the direction close to the middle position of the electroplating tank 11 in the state of being in contact with and abutting against the bottom wall of the electroplating tank 11. And during this process, the disturbing member 434 will rotate relative to the rotating rod 433, disturbing the nickel adhering to the bottom wall of the electroplating tank 11 and also being able to disturb the surrounding electroplating solution.

[0074] After that, during the process of the lifting frame 411 moving upward from bottom to top, the operation law of the disturbing assembly 43 can be deduced by the same reason, and it can again have a disturbing effect on the nickel adhering to the wall of the electroplating tank 11 and the surrounding electroplating solution on the moving path.

[0075] The implementation principle of the nickel plate electroplating forming cell for a light guide plate in the embodiment of the present application is as follows: During the process of electroplating and forming the nickel plate for the light guide plate 5, first, the light guide plate 5 is clamped and positioned by the clamping assembly 22 and the light guide plate 5 is completely immersed in the electroplating solution, then a suitable mesh plate 31 is selected according to the concave dot structure on the light guide plate 5 and installed on the cell body 1, and then the electrolysis assembly 21 is controlled to operate to electrolyze the electroplating solution to obtain nickel, and at the same time, the stirring device 4 is controlled to operate; During the operation of the stirring device 4, the lifting assembly 41 will cause the plurality of flow-pushing assemblies 42 and the plurality of disturbing assemblies 43 to move up and down repeatedly; during the up-and-down movement of the flow-pushing assembly 42, it can drive the electroplating solution in the electroplating tank 11 to flow towards the direction close to the light guide plate 5, so that the nickel obtained by electrolyzing the electroplating solution by the electrolysis assembly 21 can flow through the mesh plate 31 with the electroplating solution and adsorb on the light guide plate 5 to form a nickel plate with a certain thickness; at the same time, the disturbing assembly 43 can disturb the electroplating solution in the electroplating tank 11 while minimizing the impact on the flow-pushing effect of the flow-pushing assembly 42, improve the uniformity of the electroplating solution, and can disturb the nickel attached to the inner wall of the electroplating tank 11 to improve the efficiency and effect of nickel adsorption on the light guide plate 5 to form a nickel plate.

[0076] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
