Description

Technical Field

The PCB module of the display panel has an interface, and one end of the test connection circuit board (usually a flexible circuit board, FPC) is connected to the interface on the PCB module, and the other end is connected to the test fixture. A piano cover is provided at the interface position on the PCB module of the display panel. The piano cover can be rotated to open and close. Pressing the piano cover can clamp one end of the FPC, so that the gold finger of the FPC is in contact with the gold finger of the interface of the PCB module of the display panel. When the piano cover is opened, the FPC can be removed from the PCB module of the display panel, thereby disconnecting the electrical connection between the display panel and the signal generator.

[0037] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0038] Referring to FIGS. 1 to 3 , the present application provides an FPC automatic plugging device 100, which includes a carrier 110, a plugging mechanism 120, and a sensing mechanism 130. The FPC automatic plugging device 100 is configured to plug the FPC 200 onto the PCB board 300, so that the PCB board 300 can be electrically connected to the signal generator, and components (such as display panels, mobile phones, etc.) provided with the PCB board 300 can be tested, powered on, and other operations.

[0039] The carrier 110 has a first carrier position 111 and a second carrier position 112. The first carrier position 111 is used to accommodate the FPC 200 to be plugged in, and the second carrier position 112 is used to accommodate the PCB board 300. Exemplarily, the first carrier position 111 and the second carrier position 112 are both contoured cavities opened on the carrier 110 to accommodate the FPC 200 and the PCB board 300.

[0040] The plug-in mechanism 120 is arranged on the carrier 110 by welding, screwing, etc. The plug-in mechanism 120 is used for adsorption and pickup of the FPC 200, and the plug-in mechanism 120 can move between the first carrier position 111 and the second carrier position 112. Specifically, referring to FIG. 2 , the plug-in mechanism 120 includes an adsorption component 121 and an opening and closing cover component 122. The adsorption component 121 is used for adsorbing the FPC 200, and the opening and closing cover component 122 is used for opening or closing the piano cover on the PCB board 300. Specifically, when the FPC200 needs to be plugged into the PCB board 300, first, the plug-in mechanism 120 moves to the first load-bearing position 111, and the FPC200 accommodated in the first load-bearing position 111 is adsorbed and picked up by the adsorption component 121; then, the plug-in mechanism 120 moves to the second load-bearing position 112 with the FPC200; then, the piano cover on the PCB board 300 is opened by the opening and closing cover component 122 to expose the interface of the PCB board 300; then, the plug-in mechanism 120 inserts the FPC200 into the interface of the PCB board 300; finally, the opening and closing cover component 122 covers the piano cover of the PCB board 300 to stably plug the FPC200 into the PCB board 300.

[0041] The sensing mechanism 130 is disposed on the carrier 110 by welding, screwing, etc. The sensing mechanism 130 is used to obtain the magnitude and direction of the plugging force during the plugging process of the FPC 200 and the PCB board 300 to adjust the action of the plugging mechanism 120. Specifically, during the plugging process of the FPC 200 and the PCB board 300, if there is a deviation in the interface position relationship between the FPC 200 and the PCB board 300, the magnitude and direction of the plugging force during the plugging process of the FPC 200 and the PCB board 300 will change accordingly, that is, the magnitude and direction of the plugging force during the plugging process of the FPC 200 and the PCB board 300 deviate from the predetermined value. In this embodiment, the plugging force magnitude and direction of FPC200 and PCB board 300 during the plugging process are obtained by the sensing mechanism 130 to sense whether the plugging position of FPC200 and PCB board 300 is accurate. If the plugging force magnitude and direction of FPC200 and PCB board 300 obtained by the sensing mechanism 130 are inconsistent with the predetermined value, the plugging force magnitude and direction deviation signal can be fed back by the sensing mechanism 130 and the plugging mechanism 120 can be adjusted, and then the plugging position relationship of the interface of FPC200 and PCB board 300 can be adjusted and compensated by the plugging mechanism 120 to reduce or even eliminate the matching error between FPC200 and PCB board 300. It should be noted that in this application, the sensing mechanism 130 can be directly set on the carrier 110; the sensing mechanism 130 can also be set on the plugging mechanism 120, and the sensing mechanism 130 is indirectly set on the carrier 110 through the plugging mechanism 120.

[0042] The above-mentioned FPC automatic plug-in device 100 can realize the automatic plug-in of FPC200 on PCB board 300 through the movement of the plug-in mechanism 120 between the first bearing position 111 and the second bearing position 112, and during the plug-in process of FPC200 and PCB board 300, the sensing mechanism 130 obtains the size and direction of the plug-in force to adjust the plug-in mechanism 120, and adjusts and compensates the plug-in position relationship of the interface between FPC200 and PCB board 300 through the plug-in mechanism 120, so as to reduce or even eliminate the matching error between FPC200 and PCB board 300, and improve the signal stability after the plug-in of FPC200 and PCB board 300.

[0043] In one embodiment, referring to FIG. 1 and FIG. 2 , the FPC automatic plug-in device 100 further includes a control module (not shown). The control module is connected to the sensing mechanism 130 in communication. For example, the control module can be connected to the sensing mechanism 130 in communication via a wire, Bluetooth, WIFI, etc. The control module is disposed on the carrier 110. For example, in the present embodiment, the control module can be disposed on the plug-in mechanism 120 in an internal or external manner, and the control module is indirectly disposed on the carrier 110 via the plug-in mechanism 120. The sensing mechanism 130 is used to obtain the magnitude and direction of the plug-in force during the plug-in process of the FPC 200 and the PCB board 300, and the control module is used to control the action of the plug-in mechanism 120 according to the magnitude and direction of the plug-in force during the plug-in process of the FPC 200 and the PCB board 300. Specifically, when the plug-in mechanism 120 absorbs and picks up the FPC200 to be plugged in and moves to the second bearing position 112, and there is a deviation in the interface position between the FPC200 and the PCB board 300, at this time, the size and direction of the plug-in force of the FPC200 during the insertion into the PCB board 300 will change, and the sensing mechanism 130 obtains the degree of deviation of the size and direction of the plug-in force, and feeds back the deviation signal of the size and direction of the plug-in force during the plug-in process of the FPC200 and the PCB board 300 to the control module. The control module calculates the deviation angle and the deviation size, and controls the plug-in mechanism 120 through the control module to adjust and compensate for the plug-in position relationship of the interface between the FPC200 and the PCB board 300, so as to reduce or even eliminate the matching error between the FPC200 and the PCB board 300, and improve the signal stability after the FPC200 and the PCB board 300 are plugged in.

[0044] Among them, in this embodiment, the sensing mechanism 130 is a six-dimensional force sensor, which can obtain and feedback the size and direction of the plugging force during the plugging process of the FPC 200 and the PCB board 300. The control module can be a programmable logic controller (PLC), a microcontroller unit (MCU) or other control components. The specific component type of the control module is not limited in this application.

[0045] Since the position of the FPC 200 placed in the first bearing position 111 may be deviated, or the plug-in mechanism 120 has a material picking position deviation when sucking and picking up the FPC 200, the plug-in mechanism 120 plugs the sucked and picked up FPC 200 into the PCB board 300, resulting in a position matching deviation. For this reason, in one embodiment, referring to FIG. 1, the FPC automatic plug-in device 100 also includes two camera modules 140. The two camera modules 140 are both arranged on the bearing platform 110, and the axes of the two camera modules 140 are coplanar and perpendicular to each other. The plug-in mechanism 120 can also move to the intersection of the axes of the two camera modules 140. Exemplarily, the two camera modules 140 are respectively defined as a first camera module 141 and a second camera module 142. The axis of the first camera module 141 extends along the Z direction shown in FIG. 1 , and the axis of the second camera module 142 extends along the Y direction shown in FIG. 1 . When the plug-in mechanism 120 moves the FPC200 to the intersection of the axes of the two camera modules 140, the first camera module 141 can obtain the X, Y coordinate values ​​of the FPC200, and the second camera module 142 can obtain the X, Z coordinate values ​​of the FPC200, that is, the FPC200 can be three-dimensionally photographed and aligned through the two camera modules 140.

[0046] Specifically, when the FPC200 needs to be plugged into the PCB board 300, first, the plug-in mechanism 120 moves to the first carrying position 111, and the FPC200 accommodated in the first carrying position 111 is adsorbed and picked up by the adsorption component 121; then, the plug-in mechanism 120 continues to move with the FPC200 to the intersection of the axes of the two camera modules 140, and the FPC200 is three-dimensionally photographed and aligned by the two camera modules 140 to obtain the coordinate position of the FPC200 on the plug-in mechanism 120, and the obtained coordinate value of the FPC200 is compared with the preset coordinate value. When the difference is detected, the deviation of FPC200 is compensated by the movement of the plug-in mechanism 120, so as to reduce or even eliminate the subsequent plug-in matching error between FPC200 and PCB board 300; then, the plug-in mechanism 120 moves to the second bearing position 112 with the FPC200 after photographing and alignment; then, the opening and closing cover assembly 122 opens the piano cover on the PCB board 300 to expose the interface of the PCB board 300; then, the plug-in mechanism 120 inserts the FPC200 into the interface of the PCB board 300; finally, the opening and closing cover assembly 122 covers the piano cover of the PCB board 300 to stably clamp the FPC200 on the PCB board 300.

[0047] It should be noted that, in other feasible embodiments, the plug-in mechanism 120 can first move to the second bearing position 112, open the piano cover on the PCB board 300 through the opening and closing cover assembly 122, and then the plug-in mechanism 120 can move to the first bearing position 111, the intersection of the axes of the two camera modules 140 and the second bearing position 112 in sequence to perform corresponding actions. In addition, the plug-in mechanism 120 can also first move to the first bearing position 111 to perform the action of taking the FPC200, and then the plug-in mechanism 120 can move to the second bearing position 112, open the piano cover on the PCB board 300 through the opening and closing cover assembly 122, and finally the plug-in mechanism 120 can move to the intersection of the axes of the two camera modules 140 and the second bearing position 112 in sequence to perform corresponding actions. The specific movement path of the plug-in mechanism 120 is not limited in this application, and it is only necessary that the plug-in mechanism 120 can perform the alignment and plugging actions of the FPC200.

[0048] Further, referring to FIG. 1 and FIG. 4 , the first camera module 141 includes a first base 1411, a first adjustment platform 1412 and a first camera 1413. The first base 1411 is arranged on the carrier 110 by means of screw connection, welding, etc., the first adjustment platform 1412 is arranged on the first base 1411 by means of screw connection, welding, etc., and the first camera 1413 is arranged on the first adjustment platform 1412 by means of screw connection, welding, etc. The first adjustment platform 1412 is used to adjust the position of the first camera 1413 in multiple directions, so that when the light emitting area of ​​the first camera 1413 deviates from the shooting area of ​​the FPC200, or when the shooting area of ​​the FPC200 changes, the first camera 1413 can be fine-tuned in any one or more directions by the first adjustment platform 1412 to move the light emitting area of ​​the first camera 1413 to a position overlapping with the shooting area of ​​the FPC200, so that the first camera 1413 can accurately obtain the X and Y coordinate values ​​of the FPC200. Similarly, referring to FIG. 1 and FIG. 5 , the second camera module 142 includes a second base 1421, a second adjustment platform 1422 and a second camera 1423. The second base 1421 is disposed on the carrier 110 by screwing, welding, etc., the second adjustment platform 1422 is disposed on the second base 1421 by screwing, welding, etc., and the second camera 1423 is disposed on the second adjustment platform 1422 by screwing, welding, etc. The second adjustment platform 1422 is used to adjust the position of the second camera 1423 in multiple directions, so that when the light emitting area of ​​the second camera 1423 deviates from the shooting area of ​​the FPC 200, or when the shooting area of ​​the FPC 200 changes, the second camera 1423 can be fine-tuned in any one or more directions by the second adjustment platform 1422 to move the light emitting area of ​​the second camera 1423 to a position that overlaps with the shooting area of ​​the FPC 200, so that the second camera 1423 can accurately obtain the X and Z coordinate values ​​of the FPC 200.

[0049] In one embodiment, referring to FIG. 1 and FIG. 2 , the plug-in mechanism 120 further includes a mechanical arm 123 and a mounting frame 124. The mounting frame 124 is rotatably disposed at the end of the mechanical arm 123, and the opening and closing cover assembly 122 and the adsorption assembly 121 are respectively disposed on opposite sides of the mounting frame 124. Exemplarily, the mounting frame 124 is a U-shaped structure as a whole, the adsorption assembly 121 is disposed on one side of the mounting frame 124 by screwing, welding, etc., and the opening and closing cover assembly 122 is disposed on the other side of the mounting frame 124 by screwing, welding, etc. Since a piano cover is disposed at the interface position of the PCB board 300, before the FPC 200 is plugged into the PCB board 300, the piano cover at the interface position of the PCB board 300 needs to be opened by the opening and closing cover assembly 122, and after the FPC 200 is plugged into the PCB board 300, the piano cover at the interface position of the PCB board 300 needs to be closed by the opening and closing cover assembly 122. Among them, in this embodiment, when the plug-in mechanism 120 moves to the second bearing position 112, first, the mounting frame 124 rotates relative to the mechanical arm 123, so that the opening and closing cover assembly 122 rotates to the side close to the interface position of the PCB board 300, and the piano cover on the PCB board 300 is opened by the opening and closing cover assembly 122 to expose the interface of the PCB board 300; then, the mounting frame 124 continues to rotate relative to the mechanical arm 123, so that the adsorption assembly 121 rotates to the side close to the interface position of the PCB board 300, and the mechanical arm 123 drives the FPC200 adsorbed on the adsorption assembly 121 to be inserted into the interface of the PCB board 300; finally, the mounting frame 124 then rotates relative to the mechanical arm 123, so that the opening and closing cover assembly 122 rotates again to the side close to the interface position of the PCB board 300, and the piano cover of the interface position of the PCB board 300 is covered by the opening and closing cover assembly 122 to stably clamp the FPC200 on the PCB board 300.

[0050] Among them, in this embodiment, the robot arm 123 can be a six-axis robot, an eight-axis robot or other flexible robot. This application does not limit the number of axes of the robot arm 123. It is only necessary that the robot arm 123 can meet the motion requirements in this application.

[0051] In order to realize the adsorption and picking operation for FPC200, in one embodiment, referring to FIG. 1-FIG. 3, the adsorption component 121 includes an adsorption plate 1211 and a plurality of first adsorption holes 1212. The adsorption plate 1211 is arranged on the mounting frame 124 by screwing, welding, etc., and a plurality of first adsorption holes 1212 are all provided on the adsorption plate 1211, and the plurality of first adsorption holes 1212 are used to adsorb the main body of FPC200. Exemplarily, by changing the air volume in the first adsorption holes 1212, the plurality of first adsorption holes 1212 can adsorb the FPC200 to be plugged onto the adsorption plate 1211 through the negative pressure, so as to realize the adsorption and picking operation of the adsorption component 121 for FPC200.

[0052] Since FPC200 is flexible and a reinforcement plate is provided on one side of the end of FPC200, when FPC200 is transported, the end of FPC200 provided with the reinforcement plate is susceptible to the adverse effect of shaking due to the gravity of the reinforcement plate, which may cause FPC200 to bend or even damage the internal circuit. To this end, in one embodiment, referring to Figures 1-3, the adsorption component 121 also includes a plurality of second adsorption holes 1213. The plurality of second adsorption holes 1213 are all provided on the adsorption plate 1211, and the plurality of second adsorption holes 1213 are used to adsorb the reinforcement plate of FPC200. Through the cooperation of the second adsorption holes 1213 and the first adsorption holes 1212, the FPC200 can be stably adsorbed on the adsorption plate 1211 as a whole, avoiding the adverse effect of shaking of FPC200 during transportation, so as to improve the stability of FPC200 during transportation.

[0053] Among them, as shown in the present embodiment, referring to FIG. 3 , the number of the first adsorption holes 1212 is seven, and the seven first adsorption holes 1212 are arranged in an array on the adsorption plate 1211, and the number of the second adsorption holes 1213 is four, and the four second adsorption holes 1213 are arranged in an array on one side of the adsorption plate 1211 close to the edge. Of course, in other feasible embodiments, the number of the first adsorption holes 1212 and the second adsorption holes 1213 can also be other, and the present application does not limit the specific number of the first adsorption holes 1212 and the second adsorption holes 1213.

[0054] In order to realize the opening and closing operations of the piano cover on the PCB board 300, in one embodiment, referring to FIG. 1 and FIG. 2, the opening and closing cover assembly 122 includes a limit block 1221 and a lifting cover member 1222. The limit block 1221 is set on the mounting frame 124 by means of screw connection, welding, etc., and the flip cover member 1222 is movably set on the limit block 1221. The flip cover member 1222 can be indirectly connected to the mounting frame 124 through the limit block 1221, so that the flip cover member 1222 can move with the mechanical arm 123. The piano cover on the PCB board 300 is opened or closed by the flip cover member 1222, so that the FPC200 can be plugged into the PCB board 300. After the FPC200 is plugged into the PCB board 300, the flip cover member 1222 covers the piano cover of the PCB board 300, so that the FPC200 can be stably connected to the PCB board 300, thereby improving the signal stability after the FPC200 and the PCB board 300 are plugged.

[0055] Specifically, referring to FIG. 1, FIG. 2 and FIG. 6, the flip cover 1222 includes a base 1223, a connection portion 1224 and a flipping portion 1225. The base 1223 is movably disposed on the limit block 1221, and the two opposite ends of the connection portion 1224 are respectively connected to the base 1223 and the flipping portion 1225, and the connection portion 1224 is recessed toward the inner side of the base 1223, that is, the connection portion 1224 is recessed inward from the base 1223 and connected to the flipping portion 1225. Referring to FIG. 6, the flip cover 1222 is a contoured chamfered structure, which reduces the damage of the flip cover 1222 to the piano cover during the process of opening the piano cover, and the flipping portion 1224 is not easily damaged. 25 is a thin sheet structure, which facilitates the lifting portion 1225 to extend into the gap between the piano cover and the PCB board 300 to open the piano cover, and the connecting portion 1224 is recessed toward the inner side of the base 1223, so that the length of the lifting portion 1225 that can extend into the gap between the piano cover and the PCB board 300 is increased, so that the force that the lifting portion 1225 can act on the piano cover is increased, which further facilitates the lifting portion 1225 to extend into the gap between the piano cover and the PCB board 300 to open the piano cover.

[0056] Further, referring to FIG. 1 , FIG. 2 and FIG. 6 , the opening and closing cover assembly 122 further includes a movable plate 1226 and at least one elastic member 1227. The movable plate 1226 is provided with a gap in the limit block 1221, and the movable plate 1226 can move relative to the limit block 1221, wherein during the movement of the movable plate 1226 relative to the limit block 1221, the gap between the movable plate 1226 and the limit block 1221 increases or decreases. The base 1223 is connected to the movable plate 1226, and preferably, the base 1223 is integrally formed on the movable plate 1226 by extrusion, injection molding, etc., so as to simplify the molding process of setting the base 1223 on the movable plate 1226 and improve the structural strength between the cover member 1222 and the movable plate 1226. The elastic member 1227 is arranged at the gap between the limit block 1221 and the movable plate 1226, and the deformation direction of the elastic member 1227 is consistent with the movable direction of the movable plate 1226, such as one end of the elastic member 1227 is connected to the limit block 1221, and the other end of the elastic member 1227 is connected to the movable plate 1226. When the opening and closing cover assembly 122 needs to cover the piano cover of the PCB board 300, the lifting cover member 1222 moves to the side close to the interface position of the PCB board 300 under the drive of the mechanical arm 123, and at the same time, the lifting cover member 1222 abuts against the piano cover of the PCB board 300, so that the piano cover moves toward the direction of the FPC 200, and after the piano cover of the PCB board 300 is reset, the FPC 200 can be stably clamped on the PCB board 300. Since the flip cover 1222 is connected to the movable plate 1226, when the flip cover 1222 contacts the piano cover on the PCB board 300, the piano cover of the PCB board 300 will exert a reaction force on the flip cover 1222, and the movable plate 1226 floats relative to the limit block 1221. The elastic member 1227 buffers the reaction force exerted by the piano cover on the flip cover 1222, so that the flip cover 1222 and the piano cover are in flexible contact during the process of closing the piano cover on the PCB board 300, avoiding hard contact between the flip cover 1222 and the piano cover, and reducing the damage to the piano cover caused by the flip cover 1222 during the process of closing the piano cover. Among them, the elastic member 1227 can only move between the gap between the limit block 1221 and the movable plate 1226, so as to limit the elastic variable of the elastic member 1227, prevent the elastic amount of the elastic member 1227 from exceeding the preset range, and protect the elastic member 1227. Furthermore, after the flip cover member 1222 completes the closing action of the piano cover on the PCB board 300 , the elastic member 1227 can reset the flip cover member 1222 .

[0057] In this embodiment, the elastic member 1227 is a reset spring, and the elastic member 1227 can be deformed after being subjected to force, and the elastic member 1227 can be elastically reset when the external force applied to the elastic member 1227 is removed. Of course, in other feasible embodiments, the elastic member 1227 can also be an elastic sheet or other element capable of elastic deformation, and the specific element type of the elastic member 1227 is not limited by this application.

[0058] Furthermore, referring to FIG. 1 , FIG. 2 and FIG. 6 , the opening and closing cover assembly 122 further includes a guide rod 1228, which is disposed between the stop block 1221 and the movable plate 1226. When the movable plate 1226 floats relative to the stop block 1221, the guide rod 1228 can limit the movement path of the movable plate 1226, so that the lifting cover member 1222 can open or close the piano cover on the PCB board 300 according to a preset path.

[0059] In one embodiment, as shown in FIG. 1 , the area of ​​the carrier 110 near the first carrier position 111 has a magnetic adsorption property, so that when the FPC 200 is placed in the first carrier position 111, the carrier 110 can adsorb the FPC 200 placed in the first carrier position 111 and perform a leveling operation on the FPC 200 placed in the first carrier position 111. Since the FPC 200 is flexible, the FPC 200 may bend, warp, fold, etc. in a natural state. If the FPC 200 is not leveled, the mechanical arm 123 may deviate from the preset position when the mechanical arm 123 adsorbs and picks up the FPC 200, resulting in a matching error between the subsequent interface of the FPC 200 and the PCB board 300. In the present application, the FPC200 to be adsorbed and picked up is leveled by the support platform 110, which can ensure that the subsequent robot arm 123 adsorbs and picks up the FPC200 according to the preset position, so as to improve the matching accuracy between the interface of the FPC200 and the PCB board 300, thereby improving the signal stability between the FPC200 and the PCB board 300.

[0060] In this embodiment, a magnet may be embedded in the support platform 110 near the first support position 111, and the FPC 200 may be adsorbed and leveled by the magnetic attraction of the magnet, so as to facilitate the subsequent adsorption and picking operation of the FPC 200 to be plugged by the plug-in mechanism 120.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
