Further, it should be further noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
FIG. 1 is a schematic diagram illustrating a structure of a flexible printed circuit board and a display panel after the flexible printed circuit board and the display panel are completely laminated according to the prior art;
as shown in fig. 1, the charges and the control signals required for driving the pixels in the display panel 10 are all from an external printed circuit board, and need to be transmitted to the display panel 10 through the flexible circuit board 20, that is, one end of the flexible circuit board 20 is connected to the display panel 10, and the other end is connected to the external printed circuit board. The display panel 10, the flexible circuit board 20 and the external printed circuit board are required to be sequentially pressed, specifically, the flexible circuit board 20 includes a plurality of pins, L is the longitudinal length of the flexible circuit board 20, and W is the transverse width of the flexible circuit board 20, the display panel 10 further includes a panel terminal 11, the panel terminal includes a plurality of pins (not shown in the figure), the pins in the panel terminal 10 correspond to the pins in the flexible circuit board 20 one to one, and false pressing is performed to ensure the alignment precision of the flexible circuit board 20 and the display panel 10.
The flexible circuit board 20 is pressed on the display panel 10, the flexible circuit board 20 is inclined relative to the display panel 10, the inclined angle is a, y is the angle shift amount after the flexible circuit board is pressed, x is the displacement amount of the flexible circuit board relative to the external printed circuit board in the transverse direction, wherein,
tan a＝y/W＝x/L，x＝(L/W)*y；
the above equation shows that when the inclination angle a is fixed, the smaller the transverse width W of the flexible circuit board or the larger the longitudinal length L, the larger the displacement x of the external printed circuit board and the flexible circuit board 20 in the transverse direction, and further limits the range of the precision requirement for the overall alignment of the external printed circuit board and the flexible circuit board 20.
FIG. 2 is a schematic diagram illustrating a structure of a flexible printed circuit board after the flexible printed circuit board is lengthened and the flexible printed circuit board is completely laminated with a display panel according to the prior art;
as shown in fig. 2, after the flexible printed circuit board 20 is lengthened, under the condition that the inclination angle is not changed, the displacement x of the flexible printed circuit board 20 in the transverse direction relative to the external printed circuit board is larger, and when the flexible printed circuit board 20 and the external printed circuit board are pressed together, the requirement on the accuracy of the overall alignment between the external printed circuit board and the flexible printed circuit board 20 is higher. Meanwhile, due to the physical properties of the flexible printed circuit board 20, the flexible printed circuit board 20 is significantly deformed after being lengthened, which results in poor contact between the external printed circuit board and the flexible printed circuit board 20. When the length of the flexible circuit board is increased, the flexible circuit board itself is also deformed, and the deformation may cause a deviation between one side of the external printed circuit board and the flexible circuit board 20, so that the yield of subsequent products is affected.
In the prior art, the contact range between the external printed circuit board and the flexible circuit board 20 can be larger by increasing the Pitch (Pitch) of the external printed circuit board, and the requirement for the overall alignment accuracy between the external printed circuit board and the flexible circuit board 20 is reduced. However, the method of increasing the Pitch (Pitch) of the external printed circuit board may cause a large variation in the material of the external printed circuit board, and the overall size of the external printed circuit board may also increase, which is not suitable for the case of limiting the size of the external printed circuit board.
Further, due to the deformation of the flexible printed circuit board 20, the external printed circuit board cannot be directly aligned with the flexible printed circuit board when being pressed with the flexible printed circuit board, and in the prior art, when the external printed circuit board is pressed with the flexible printed circuit board 10, the two sides of the display panel 10 pressed with the flexible printed circuit board are usually identified and aligned, so that the identification precision is low.

FIG. 4 is a partial schematic structural view of an alignment mechanism provided in accordance with the present invention;
as shown in fig. 4, the first supporting platform 42 includes a groove 421 having a thickness corresponding to the thickness of the flexible circuit board 20 for accommodating the flexible circuit board 20, and further, a vacuum hole 422 is further disposed at the bottom of the groove 421 in the first supporting platform 42, when the flexible circuit board 20 is placed in the groove, the vacuum hole 422 sucks the bottom of the flexible circuit board 20 flat, and the pressing block 411 presses the flexible circuit board 20 in its entirety, thereby effectively preventing the flexible circuit board 20 from warping after being lengthened.
FIG. 5 illustrates a partial cross-sectional view of an alignment mechanism provided in accordance with the present invention;
as shown in fig. 5, the groove 421 in the first supporting platform 42 is an upward slope and a downward vertical structure, the size of the opening at the top of the groove 421 is larger than the size of the opening at the bottom of the groove, so that the flexible circuit board 20 can be more easily placed into the groove 421, and the portion of the side wall of the groove close to the bottom is perpendicular to the bottom, for example, the width h of the vertical position of the bottom of the groove 421 is 30um larger than the width of the flexible circuit board 20, and when a margin is left, a large inclined included angle of the flexible circuit board 20 relative to the display panel 10 when the flexible circuit board 20 is pressed against an external printed circuit board is effectively avoided.
Further, the first embodiment solves the problem of deformation of the flexible printed circuit board 20, and after the flexible printed circuit board 20 is lengthened, the overall alignment between the external printed circuit board and the flexible printed circuit board 20 can still be realized, so that the limitation on the length of the flexible printed circuit board 20 in the prior art is broken through, and meanwhile, when the alignment between the flexible printed circuit board 10 and the external printed circuit board is realized, the alignment between the two sides of the flexible printed circuit board 10 and the external printed circuit board is identified through the image system, so that the identification precision is greatly improved.
Fig. 6 is a partial schematic structural diagram of an alignment mechanism provided according to a second embodiment of the present invention.
Fig. 7 is a schematic view showing the overall structure of an aligning mechanism according to a second embodiment of the present invention.
Similar to the first embodiment of the present invention, the alignment mechanism provided in the second embodiment of the present invention also includes a whole surface pressing mechanism, a supporting platform mechanism 43 and a carrying mechanism 40, and the same parts are not repeated herein, and the structure different from the first embodiment of the present invention includes a plurality of positioning mechanisms 52 disposed on one side of the supporting platform, wherein the positioning mechanisms 52 may be disposed in the second supporting platform supporting the display panel 10 or the first supporting platform 42 supporting the flexible circuit board, and the positioning cylinders 51 connected to the positioning mechanisms 52 drive the positioning mechanisms 52 to move, so as to drive the display panel 10 or the flexible circuit board 20 to move to a predetermined position (for example, move the flexible circuit board 20 into the groove 421), the whole surface pressing mechanism in the present embodiment includes pressing blocks 411 and pressing cylinders 412 connected thereto, wherein the pressing blocks 411 surround the periphery of the adsorption arms disposed corresponding to the positions of the flexible circuit board 20, and is adjacent to an end of the adsorption arm for pressing the flexible circuit board 20, and a pressing cylinder 412 for driving the pressing block 411.
In the above embodiment, the position of the carrying device 40 that adsorbs the flexible circuit board 20 and the display panel 10 pressed together and moves to the supporting platform mechanism 43 is not accurate, and the plurality of positioning mechanisms 52 drive the display panel 10 or the flexible circuit board 20 to move to the predetermined position for fine adjustment, so as to solve the above problem, and meanwhile, the pressing block 411 in the pressing and finishing mechanism is driven by the pressing cylinder 412 to make the force adjustment of the whole pressing surface more accurate, so as to prevent the circuit from being damaged due to too large force or the effect of preventing the deformation of the whole pressing surface due to too small force.
It should be noted that as used herein, the words "during", "when" and "when … …" in relation to the operation of a circuit are not strict terms indicating an action that occurs immediately upon the start of a startup action, but rather there may be some small but reasonable delay or delays, such as various transmission delays, between it and the reaction action (action) initiated by the startup action. The words "about" or "substantially" are used herein to mean that the value of an element (element) has a parameter that is expected to be close to the stated value or position. However, as is well known in the art, there is always a slight deviation that makes it difficult for the value or position to be exactly the stated value. It has been well established in the art that a deviation of at least ten percent (10%) for a semiconductor doping concentration of at least twenty percent (20%) is a reasonable deviation from the exact ideal target described. When used in conjunction with a signal state, the actual voltage value or logic state (e.g., "1" or "0") of the signal depends on whether positive or negative logic is used.
In accordance with the present invention, as described above, these embodiments do not set forth all of the details or limit the utility model to only the specific embodiments described. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, to thereby enable others skilled in the art to best utilize the utility model and various embodiments with various modifications as are suited to the particular use contemplated. The scope of the utility model should be determined with reference to the appended claims and their equivalents.
