[0066] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application; and the technical features designed in different implementation manners of the present application described below can be combined with each other as long as there is no conflict. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0067] In the description of the present application, it should be noted that all the terms (including technical terms and scientific terms) used in the present application have the same meanings as those generally understood by a person of ordinary skill in the art to which the present application belongs, and should not be understood as a limitation of the present application; it should be further understood that the terms used in the present application should be understood as having the same meanings as the meanings of these terms in the context of the present specification and the related art, and should not be understood in an idealized or overly formal sense, unless defined explicitly in the present application.

[0068] With reference to Figures 1 to 4 , the present application provides an embodiment of a panel assembling machine, comprising

[0069] a first feeding carrier 110 for placing a panel 111 and a second feeding carrier 120 for placing a back plate 121;

[0070] The panel 111 on the first feeding carrier 110 needs to be fixed and transferred to a film tearing mechanism 300 for film tearing treatment before being assembled with the back plate 121, so that the panel 111 has adhesion and can be pasted with the back plate 121 to complete the assembly.

[0071] The assembly arm 200 here has the functions of fixing the panel 111 and rotating and translating for transferring the panel 111. Those skilled in the art can use conventional technical means and combinations in the art to achieve the above-mentioned functions. For example, the assembly arm 200 specifically includes a vacuum suction cup for adsorbing and fixing the panel 111, as well as a rotating device for driving the vacuum suction cup to rotate and a linear drive device for linear movement, but is not limited thereto.

[0072] The film-peeling mechanism 300 includes a rubber roller 310 with adhesive tape 350 attached to it for adhering the film material on the panel 111. The film material is peeled off the panel 111 by the relative movement between the panel 111 and the rubber roller 310. The relative movement between the panel 111 and the rubber roller 310 can take three forms: first, the panel 111 is stationary while the rubber roller 310 moves under the drive of a driving device; second, the rubber roller 310 is stationary while the panel 111 moves under the drive of a driving device; third, the panel 111 and the rubber roller 310 each move in opposite directions under the drive of a driving device.

[0073] Figure 5 The illustrated embodiment is the first type. The film-tearing mechanism includes a film-tearing frame 301, and a rubber roller 310 is fixed to the film-tearing frame 301 via a linear drive device. During the film-tearing process, the panel 111 is fixed to the assembly arm 200 and remains stationary. The rubber roller 310 moves under the drive of the linear drive device, thereby tearing the film material off the panel 111. To facilitate film tearing, the rubber roller 310 typically first adheres to one corner of the panel 111 and then tears it open.

[0074] After the membrane material is removed, the panel 111 is transferred to the first alignment mechanism 112 via the assembly arm 200, and the back plate 121 on the second feeding platform 120 is also pre-transferred to the second alignment mechanism via the handling assembly.

[0075] Specifically, such as Figure 1 As shown, the first alignment mechanism 112 is equipped with a CCD camera, with the lens of the CCD camera facing upwards to capture position information on the panel 111 located above it.

[0076] The second alignment mechanism includes a transparent stage 123 and a CCD camera located below the transparent stage 123. A backplate 121 is placed on the transparent stage 123, and the lens of the CCD camera faces upward to capture position information on the backplate 121.

[0077] The alignment process is specifically based on the position information of the back plate 121, comparing the position information on the face plate 111 and the back plate 121, and calculating the angle or displacement of the face plate 111 that needs to be adjusted through an algorithm, and then driving the assembly arm 200 to adjust and correct the face plate 111 to be consistent with the position information of the back plate 121, and then complete the alignment. It should be noted that the technical means to realize the above alignment process is the prior art, and those skilled in the art can implement it according to the actual situation, and here is not repeated.

[0078] After the above alignment is completed, the assembly arm 200 is used to transfer the face plate 111 above the back plate 121, and then move down to adhere the face plate 111 to the back plate 121, complete the assembly of the face plate 111 and the back plate 121, and then transfer the assembled face plate 111 and back plate 121 to the pressure maintaining platform 410 of the pressure maintaining mechanism 400 through the assembly arm 200, and then the assembly arm 200 continues to adsorb and fix the next face plate 111 to be torn off.

[0079] As shown in Figure 2 , the pressure maintaining mechanism 400 further comprises a pressure maintaining arm 420, which is placed on the pressure maintaining platform 410 to press the assembled face plate 111 and back plate 121 for a certain period of time, so that the face plate 111 and the back plate 121 are better adhered. After the pressure maintaining is completed, the assembled face plate 111 and back plate 121 are transferred to the turnover mechanism 500 by the conveying assembly, and the assembled face plate 111 and back plate 121 are turned over by 180°, so that the back plate 121 faces upward, facilitating subsequent code spraying.

[0080] It should be noted that those skilled in the art can use conventional technical means and combinations in the art to realize the 180° turnover of the product, therefore, the specific structure of the turnover mechanism 500 is not repeated here.

[0081] After the assembled face plate 111 and back plate 121 are turned over with the back plate 121 facing upward, they are transferred to the discharge mechanism 600 by the conveying assembly, and the back plate 121 is marked by code spraying, and then discharged.

[0082] In an embodiment, as shown in Figure 4 , the face plate 111 on the first feeding platform 110 is first transferred to a position where it can be grasped by the assembly arm 200 through the material taking fork 130. Specifically, the material taking fork 130 has a fork-shaped structure with a plurality of rods, and the surface of the first feeding platform 110 is parallelly provided with a plurality of strip-shaped grooves 113 matched with the plurality of rods. The plurality of rods 131 are embedded in the plurality of strip-shaped grooves 113, so as to lift and transfer the face plate 111 to be torn off to a position where it can be grasped by the assembly arm 200.

[0083] It should be noted that those skilled in the art can use a linear drive device to design the movement track of the material taking fork 130, which is not repeated here.

[0084] In an embodiment, as shown in Figure 4 and Figure 5 , the film tearing frame 301 is also fixed with a feeding wheel 320 for outputting the adhesive tape 350, a collecting wheel 330 for recycling the adhesive tape 350, and several guide wheels 340 for changing the direction of the adhesive tape 350, so as to ensure that the adhesive tape 350 attached to the rubber roller 310 can be updated in time and keep strong adhesion at all times, so as to smoothly carry out the film tearing process.

[0085] In an embodiment, as shown in Figure 6 , the feeding wheel 320 is connected with the rotating shaft 710 where it is located through a tensioning mechanism and realizes synchronous rotation;

[0086] In specific implementation, referring to Figure 7 , the tensioning mechanism includes a rotating lug 720 for connecting with the driving shaft of the driving device, which is sleeved on the rotating shaft 710 of the driving device and is fixedly connected with the rotating shaft 710, so that it can rotate synchronously with the rotating shaft 710;

[0087] The circumferential side of the rotating lug 720 is provided with several tensioning blocks 730, and the several tensioning blocks 730 are movable in the radial direction and are limited in the radial movement distance by a limiting assembly; specifically, the limiting assembly includes a limiting slot / hole 751 and a limiting column 752 slidingly arranged in the limiting slot / hole 751, as shown in the embodiment of Figure 7 , the limiting slot / hole 751 is arranged on the tensioning block 730, and the limiting column 752 is fixed on the fixed plate 753; similarly, the person skilled in the art can also arrange the limiting slot / hole 751 on the fixed plate 753 and fix the limiting column 752 on the tensioning block 730 according to actual needs, and the limiting column 752 can be a bolt in particular.

[0088] Each tensioning block 730 is also provided with a roller / ball 740 between the rotating lug 720, and each roller / ball 740 abuts against the first contact surface 721 of the rotating lug 720 and the second contact surface 731 of the tensioning block 730;

[0089] Referring to Figure 7 or Figure 9 , from the axial projection angle of the rotating shaft 710, the circumferential side of the rotating lug 720 is not a uniform circle, and the rotation of the rotating lug 720 necessarily changes the distance from the point where the roller / ball 740 contacts the first contact surface 721 to the axis of the rotating shaft 710, which is denoted by the letter "d" hereinafter, since the rotating lug 720 abuts against the tensioning block 730 through the roller / ball 740.

[0090] As shown in Figure 8 , the rotating lug 720 is provided with a plurality of rotating grooves 722, and the roller / ball 740 is arranged in the rotating groove 722.As shown, when the rotating block 720 rotates under the driving of the motor, the increase of d will inevitably push the tension block 730 to move outward, thereby playing a tensioning and fixing role on the unwinding wheel 320 sleeved on the tension block 730, and driving the unwinding wheel 320 to rotate synchronously.

[0091] As shown in Figure 10 , when the rotating block 720 is not driven by external force, the roller / ball 740 returns to the initial position in the natural state, that is, d will decrease, and the tension block 730 needs to move inward to abut against the roller / ball 740, at this time, it cannot play a tensioning and fixing role on the unwinding wheel 320, thereby facilitating the disassembly and assembly of the unwinding wheel 320 or the winding wheel 330.

[0092] And due to the limiting effect of the limiting assembly, the movement range of the tension block 730 is limited, no matter how the rotating block 720 rotates, each roller / ball 740 can only move within the range of the first contact surface 721 where it is located, to ensure that each tension block 730 abuts against the rotating block 720 through the roller / ball 740.

[0093] In combination with Figure 4 , Figure 8 and Figure 10 , the transmission process and principle of the adhesive tape 350 are as follows:

[0094] The motors connected to the winding wheel 330 and the unwinding wheel 320 respectively output driving forces in opposite directions, at this time, the tensioning and fixing effect of the tension block 730 on the unwinding wheel 320 makes the tension block 730 relatively stationary and synchronously rotates with the rotating block 720;

[0095] By setting the torque of the winding wheel 330 motor to be greater than that of the unwinding wheel 320 motor, the pulling force of the winding wheel 330 on the adhesive tape 350 is greater than that of the unwinding wheel 320 on the adhesive tape 350, thereby forcing the unwinding wheel 320 to rotate in the same direction as the winding wheel 330, that is, the actual rotation direction of the motor output shaft connected to the unwinding wheel 320 is opposite to the rotation driven by the motor itself.

[0096] Thus, the process of the adhesive tape 350 being output from the unwinding wheel 320 and being wound back by the winding wheel 330 for recovery is realized.

[0097] The first contact surface 721 and the second contact surface 731 at least include but are not limited to the following four forms:

[0098] ①Referring to Figures 7 to 10 , the first contact surface 721 is a plane, and the second contact surface 731 is an arc-shaped surface concave inward relative to the tension block 730.

[0099] Preferably, the second contact surface 731 is a circular arc surface, and from the axial projection angle of the rotating shaft 710, the center of the circle where the circular arc is located coincides with the axis of the rotating shaft.

[0100] ②Reference Figure 11 The first contact surface 721 is an arc-shaped surface that is concave inward relative to the rotating protrusion 720, and the second contact surface 731 is an arc-shaped surface that is concave inward relative to the tensioning block 730.

[0101] ③Reference Figure 12 The first contact surface 721 is a plane, and the second contact surface 731 is composed of at least two intersecting planes.

[0102] ④Reference Figure 13 The first contact surface 721 is a plane, and the second contact surface 731 is composed of at least two arc-shaped surfaces.

[0103] Similarly, the first contact surface 721 in ③ and ④ can also be an arc-shaped surface that is concave inward relative to the rotating protrusion 720. Those skilled in the art can make adaptive adjustments to the first and second contact surfaces based on the design concepts of the examples listed above.

[0104] In one embodiment, the two adjacent first contact surfaces 721 on the rotating protrusion 720 are also connected by a circular arc surface, and all the circular arc surfaces are located on the same circle.

[0105] Reference Figures 7 to 10 When the first contact surface 721 is a plane, the two adjacent first contact surfaces 721 on the rotating protrusion 720 are also connected by a circular arc surface, and all the circular arc surfaces are located on the same circle. The rotating protrusion 720 with this structure can be made from a cylindrical component by cutting or milling, which is easy to process.

[0106] Preferably, the number of the first contact surface 721 and the tensioning block 730 ranges from 2 to 9. Those skilled in the art can determine the specific number of the first contact surface 721 and the tensioning block 730 according to the actual size of the structure. Figures 7 to 10 In the embodiment shown, there are three first contact surfaces 721 and three tensioning blocks 730. The three first contact surfaces 721 are evenly distributed on the rotating protrusion 720, and the three tensioning blocks 730 are evenly distributed around the circumferential side of the rotating protrusion 720 to ensure the stability of the rotation of the subsequent material wheel.

[0107] In one embodiment, such as Figures 7 to 10 The tensioning block 730 shown is fan-shaped, meaning that the surface of the tensioning block 730 that contacts the material wheel is also an arc surface, further increasing the contact area between the tensioning block 730 and the material wheel, thereby strengthening the tensioning effect of the tensioning block 730 on the material wheel.

[0108] In an embodiment, the two adjacent tensioning blocks 730 are spaced apart so that a gap is left between the two adjacent tensioning blocks 730, and the two adjacent tensioning blocks 730 do not contact each other, thereby avoiding interference or obstruction to the respective radial movement.

[0109] In an embodiment, as shown in Figures 14 to 16 The discharging mechanism 600 includes a machine table 601, and the machine table 601 is provided with a movable discharging table 610 on which the finished product, i.e., the assembled panel 111 and back plate 121, to be ink-jet printed is placed.

[0110] Since the panel 111 is usually provided with a flexible circuit board 114, which is prone to warping, the ink-jet printing effect is affected. Therefore, the machine table 601 is provided with a pressing assembly 620 in the embodiment, and the pressing assembly 620 includes a pressing member 621 and a linear driving device for driving the pressing member 621 to abut or move away from the discharging table 610. When the discharging table 610 moves to the lower side of the pressing member 621, the pressing member 621 is driven by the linear driving device to move downward so as to make the flexible circuit board 114 tightly adhere to the discharging table 610, thereby preventing the flexible circuit board 114 from warping. Specifically, the pressing member 621 can be flat, long strip-shaped or thin wire-shaped according to the shape and size, and the shape and size of the pressing member can be designed according to actual needs by those skilled in the art.

[0111] After the flexible circuit board 114 is pressed by the pressing member 621 and is in a pressed state, the finished product needs to be moved to an ink-jet printing station for ink-jet printing. Before the ink-jet printing is completed, the flexible circuit board 114 needs to be kept in the pressed state and cannot be warped. Therefore, the pressing assembly 620 needs to be synchronously moved to the ink-jet printing station with the discharging table 610. The pressing assembly 620 is connected and fixed to the discharging table 610 through a linking assembly 630, so as to be synchronously moved with the discharging table 610.

[0112] After the ink-jet printing is completed, the pressing member 621 is driven by the linear driving device to move upward, thereby releasing the pressing on the flexible circuit board 114. The linking assembly 630 is adjusted to release the connection between the pressing assembly 620 and the discharging table 610. Then, the discharging table 610 continues to move the finished product to the next process, and the pressing assembly 620 is driven by a resetting assembly 640 to horizontally return to the initial position, thereby being horizontally reset and continuing to press the flexible circuit board 114 of the next finished product to be ink-jet printed. Specifically, the resetting assembly 640 can be any one of an electric push rod, a hydraulic cylinder or a pneumatic cylinder.

[0113] Preferably, referring to Figure 15 and Figure 16The compression member 621 is a linear structure extending through the width direction of the discharging platform 610. When the flexible circuit board 114 is in the compression state, the compression member 621 avoids blocking the ink-jet code of the flexible circuit board 114 as much as possible. The compression member 621 adopts a linear structure, which reduces the line diameter of the compression member 621 under the premise of ensuring the compression effect, so as to reduce the coverage area of the compression member 621 on the flexible circuit board 114. Generally, a metal wire is used as the compression member 621.

[0114] In an embodiment, referring to Figure 15 and Figure 16 , both ends of the compression member 621 are fixed on the movable end of the linear driving device through the clamp 622. The clamp 622 is used to fix both ends of the compression member 621, which facilitates the disassembly and replacement of the compression member 621.

[0115] In an embodiment, referring to Figure 15 and Figure 16 , the compression member 621 in a linear structure is provided with at least two. It is generally difficult for a single metal wire to well adhere the flexible circuit board 114 to the discharging platform 610. Therefore, two or more compression members 621 are needed to press the flexible circuit board 114. The number of the compression member 621 in a linear structure and the distance between the adjacent two compression members 621 can be adjusted by the person skilled in the art according to the actual situation, which will not be described here.

[0116] The connection assembly 630 connects and fixes the compression member 621 and the discharging platform 610 in the following ways: clamping and fixing.

[0117] In an embodiment, the connection assembly 630 includes two clamping arms 631 connected with the compression assembly 620 and arranged oppositely in up and down directions, and an ear plate 632 horizontally arranged on both sides of the discharging platform 610. The ear plate 632 is clamped and fixed by the two clamping arms 631, so that the compression assembly 620 and the discharging platform 610 can move synchronously.

[0118] In specific implementation, referring to Figure 15 , the compression assembly 620 is connected with two clamping arms 631 arranged oppositely in up and down directions. The ear plate 632 is horizontally arranged on both sides of the discharging platform 610. When the discharging platform 610 moves to the position where the ear plate 632 is located between the two clamping arms 631, the two clamping arms 631 move towards each other under the driving of the driving device, and clamp and fix the ear plate 632, so as to realize the fixed connection and synchronous movement of the compression assembly 620 and the discharging platform 610. The connection between the compression assembly 620 and the discharging platform 610 is released by the reverse movement of the two clamping arms 631.

[0119] It should be noted that the two clamping arms can also be arranged on the discharging table, and the ear plate can be arranged on the pressing assembly, and the clamping fixing process is the same, which will not be repeated here.

Specifically, the adapter wall drives the clamping protrusions to be embedded in the through holes / slots under the action of the linear driving device in the forward direction, so that the pressing assembly 620 is connected with the discharging table 610 and moves synchronously. Similarly, the adapter wall drives the clamping protrusions to be extracted from the through holes / slots under the action of the linear driving device in the reverse direction, so that the connection between the pressing assembly 620 and the discharging table 610 is released.

[0121] It should be noted that the adapter wall can also be arranged on the discharging table, and the ear plate can be arranged on the pressing assembly, and the clamping fixing process is the same, which will not be repeated here.
