[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0045] Figure 1 This is a perspective view of a screen component cable routing device according to an exemplary embodiment. Figure 2 This is a side view of a screen assembly cable routing device according to an exemplary embodiment.

[0046] like Figure 1 and Figure 2 As shown, the screen assembly cable threading device 100 of this embodiment is used to thread the screen cable into the corresponding through hole of the electronic device frame.

[0047] The electronic device can be a smart phone, a tablet computer, a notebook computer, a smart bracelet, a smart watch, or the like wearable device. In the following description, the screen wire threading of the smart phone is taken as an example for illustration, but the present disclosure is not limited thereto, and the screen assembly wire threading device of the present disclosure can also be applied to the assembly process of other electronic devices, which requires the screen wire to pass through the corresponding through hole of the middle frame.

[0048] The smart phone can include a middle frame as an inner support, a screen installed in front of the middle frame, and a mainboard installed at the back of the middle frame. Before the screen is assembled to the middle frame, the screen wire needs to be threaded through the through hole of the middle frame, so that the screen is electrically connected with the mainboard at the back of the middle frame, and then the screen is installed to the middle frame.

[0049] The screen assembly wire threading device 100 of the embodiment of the present disclosure can include a screen assembly picking mechanism 10, a wire arranging mechanism 20, and a moving mechanism 30.

[0050] The screen assembly picking mechanism 10 is used to pick up the screen with the wire, so as to keep the screen with the wire in the screen assembly picking mechanism 10 during the conveying of the screen. The wire extends from one side of the screen, for example, the screen can be substantially rectangular, and the wire can extend from the long side (side edge) of the rectangular screen. However, it is not limited thereto, and the wire of the screen can also extend from the short side (top edge) of the screen.

[0051] The wire arranging mechanism 20 is used to clamp and limit the wire of the screen, so as to limit the wire in the wire arranging mechanism 20, prevent the wire from shaking, and reduce the bending degree of the wire, so that the wire is substantially linear. The clamping and limiting can be understood as that the wire arranging mechanism 20 limits the wire in a certain space range, such as a gap for accommodating the wire, and the wire is in a drooping state in the limiting space by its own gravity and can move up and down freely, that is, the wire is in a non-clamping state.

[0052] The moving mechanism 30 drives the screen assembly picking mechanism 10 and the wire arranging mechanism 20 to move, so as to pass the clamped and limited wire through the corresponding through hole of the middle frame. The moving mechanism 30 can be a multi-axis moving mechanism, so as to drive the screen assembly picking mechanism 10 and the wire arranging mechanism 20 to move in different directions. For example, the moving mechanism 30 can be a three-axis moving mechanism, which drives the screen assembly picking mechanism 10 and the wire arranging mechanism 20 to move along the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively.

[0053] In the prior art, when the longer screen wire is threaded, the longer wire will shake and the shaking amplitude is large, and the wire is very unstable. Therefore, the wire and the through hole of the middle frame cannot always keep in alignment, which leads to a low threading success rate. In addition, the longer wire will bend, and the positions of each segment of the wire deviate from the position of the through hole of the middle frame, which cannot keep in alignment, leading to threading difficulty.

[0054] The screen assembly cable threading device 100 of this embodiment uses a cable management mechanism 20 to clamp and limit the cable within a certain space, preventing the screen cable from shaking. In addition, it also limits the bending degree of the cable, so that during the cable threading process, the clamped and limited cable and the through hole of the middle frame can be in the corresponding range (aligned state). This greatly improves the success rate of cable threading, makes the threading more accurate, and improves the threading efficiency.

[0055] In addition, through the cooperation of the moving mechanism 30, the screen component picking mechanism 10 and the cable management mechanism, the screen cable can be automatically threaded into the through hole of the middle frame without manual intervention, which greatly improves the threading efficiency and reduces labor costs.

[0056] In addition, by clamping and limiting the screen ribbon cable by the ribbon cable management mechanism 20, the ribbon cable connection segment can be prevented from tearing off the screen due to excessive shaking, thus improving the reliability of the ribbon cable connection.

[0057] Figure 5 This is a schematic diagram of the structure of a cable management mechanism according to an exemplary embodiment.

[0058] In some embodiments, such as Figure 1 and Figure 5 As shown, the cable management mechanism 20 includes a cable management component 21, which includes a first limiting component 212 and a first limiting drive component 211.

[0059] The first limiting component 212 is disposed at the driving end of the first limiting drive component 211, and the first limiting drive component 211 drives the first limiting component 212 to open or close. When the first limiting component 212 is closed, it has a first gap, within which the screen's ribbon cable 200 is confined. The first gap can be a vertically connected gap used to accommodate and confine the ribbon cable. The size of the first gap can be slightly larger than the size of the screen's ribbon cable 200. When the ribbon cable 200 is accommodated in the first gap, it can move freely up and down within the gap; that is, the ribbon cable 200 is in a non-clamped state within the first gap.

[0060] When the moving mechanism 30 drives the screen assembly picking mechanism 10 to move the picked-up screen to the cable threading position, for example, above the middle frame, the first limiting drive member 211 drives the first limiting component 212 to close, clamping and limiting the cable in the first gap, preventing the cable 200 from swaying back and forth or left and right, and can also straighten the bent cable so that the cable is roughly straight.

[0061] In the embodiments of the present disclosure, the first limiting assembly 212 is used to limit the flat cable 200 in the first gap, prevent the flat cable 200 from shaking left and right, and change the flat cable from a curved shape to a straight shape. In this way, the flat cable can be clamped and limited in the range corresponding to the through hole of the middle frame (in the aligned state) during the threading process, so that the success rate of threading can be greatly improved, the threading is more accurate, and the threading efficiency is also improved.

[0062] As an example, in the state that the first limiting driving member 211 drives the first limiting assembly 212 to close, the first limiting assembly 212 can limit the free section of the flat cable 200, so that the free section of the flat cable 200 is located in the first gap. Since the closer the flat cable 200 is to the free section, the greater the shaking angle and the greater the bending degree caused by its own stress, the first limiting assembly 212 can effectively reduce the shaking amplitude of the flat cable 200 and prevent the flat cable 200 from bending to the greatest extent. In this way, when the flat cable 200 is threaded into the through hole corresponding to the middle frame, the free section of the flat cable can always be in the range corresponding to the through hole of the middle frame (in the aligned state), so that the success rate of threading can be greatly improved, the threading is more accurate, and the threading efficiency is also improved.

[0063] In some embodiments, as shown in Figure 5 The first limiting assembly 212 includes a limiting component, and the limiting component includes a first fixed plate 213 and a first movable plate 214. The first limiting driving member 211 is a first swing cylinder, and the first swing cylinder includes a first fixed rod 215 and a first swing rod 216. The first fixed plate 213 is arranged at the end of the first fixed rod 215, and the first movable plate 214 is arranged at the end of the first swing rod 216.

[0064] When the first swing rod 216 of the first swing cylinder moves close to the first fixed rod 215 and drives the first movable plate 214 to move close to the first fixed plate 213 to the closed state, a first gap is formed between the first fixed plate 213 and the first movable plate 214, the flat cable 200 is clamped and limited in the first gap, and the flat cable 200 is limited. When the first swing rod 216 of the first swing cylinder moves away from the first fixed rod 215 and drives the first movable plate 214 to move away from the first fixed plate 213 to the open state, the first fixed plate 213 and the first movable plate 214 release the clamping and limiting of the flat cable 200.

[0065] The driving mode of the first fixed plate 213 and the first movable plate 214 is not limited to the first swing cylinder pneumatic mode. In other embodiments, the first fixed plate 213 and the first movable plate 214 can also be driven by magnetism to open or close the first fixed plate 213 and the first movable plate 214. For example, the first limiting driving member 211 can include a first electromagnet arranged on the first fixed plate 213 and a second electromagnet arranged on the first movable plate 214, wherein the second electromagnet corresponds to the first electromagnet. By energizing the first electromagnet and the second electromagnet to change the magnetic pole, the first fixed plate 213 and the first movable plate 214 can be moved close to or away from each other to limit the wire clamping or contact clamping.

[0066] In some embodiments, the wire arrangement assembly 21 further includes a first limiting block 217. The first limiting block 217 is arranged between the first fixed rod 215 and the first swing rod 216. When the first swing cylinder drives the first limiting assembly 212 to close, the first fixed rod 215 and the first swing rod 216 abut against the first limiting block 217, so that the first gap is formed between the first fixed plate 213 and the first movable plate 214, and the wire is not clamped.

[0067] By arranging the first limiting block 217 between the first fixed rod 215 and the first swing rod 216, the first gap can be formed when the first fixed plate 213 and the first movable plate 214 are closed, without changing the structure of the limiting part, and the installation is convenient.

[0068] For example, the first limiting block 217 can be detachably fixed to the first fixed rod 215 or the first swing rod 216. The first limiting block 217 can include a mounting part and a limiting part protruding downward from the mounting part. The mounting part can be fixed to the upper part of the first fixed rod 215 or the first swing rod 216 by means of bolts, buckles or the like, so that the protruding limiting part is located between the first fixed rod 215 and the first swing rod 216.

[0069] When threading the short wire, the first limiting block 217 is detached, so that the first limiting assembly 212 clamps the short wire in the closed state, and the short wire is more stable and accurate during threading, thereby being suitable for threading the short wire into the corresponding through hole of the middle frame. Therefore, the screen assembly wire threading device 100 of the embodiment of the present disclosure is detachably fixed to the first fixed rod 215 or the first swing rod 216, and is suitable for long and short wires, and has good adaptability.

[0070] The first gap formed when the first fixed plate 213 and the first movable plate 214 are closed in the above embodiment is not limited to being achieved by the first limiting block 217. In the threading scenario for long cables, the first limiting block 217 can not be needed. For example, corresponding recesses are formed on the opposite surfaces of the first fixed plate 213 and the first movable plate 214. When the first fixed plate 213 and the first movable plate 214 are closed by the first swing cylinder, the first gap is formed by the recesses on the opposite surfaces of the first fixed plate 213 and the first movable plate 214 to restrict the cable in the first gap.

[0071] In some embodiments, the cable management assembly 21 further comprises a clamping jaw assembly 218, which comprises a cable management clamping jaw 2181 and a lifting drive 2182. The lifting drive 2182 is fixed to the limiting component, and the driving end of the lifting drive 2182 is connected to the cable management clamping jaw 2181 to drive the cable management clamping jaw 2181 to lift and straighten the cable held and limited to align the free section of the cable with the through hole of the middle frame.

[0072] The free section of the cable 200 needs to be aligned with the through hole of the middle frame. Since the free section of the long cable 200 is prone to bending, the lifting drive 2182 is driven to straighten the free section of the cable 200 by the cable management clamping jaw 2181 after being ventilated, so that the free section of the cable 200 is directed towards the through hole of the middle frame to facilitate the cable 200 to pass through the through hole.

[0073] In some embodiments, the cable management assembly 21 further comprises a first positioning block 219. The first positioning block 219 is fixed to the first fixed plate 213, and the first positioning block 219 is provided with a first opening facing the first movable plate 214, which is used to accommodate the cable 200. Alternatively, the first positioning block 219 is fixed to the first movable plate 214, and the first positioning block 219 is provided with a first opening facing the first fixed plate 213, which is used to accommodate the cable 200. The first opening corresponds to the first gap.

[0074] The first opening of the first positioning block 219 facilitates the positioning of the cable to limit the displacement of the cable 200 in the front-rear direction, and the first fixed plate 213 and the first movable plate 214 limit the displacement of the cable 200 in the left-right direction. In this way, the cable 200 is limited in the first gap in the front-rear direction and the left-right direction, and the cable 200 is more stably kept corresponding to the through hole of the middle frame, the threading is more accurate, and the threading success rate is improved.

[0075] For example, the outer diameter of the first opening is larger than the inner diameter. During the movement of the first movable plate 214 close to the first fixed plate 213, the cable 200 enters the first opening from the outer end to the inner end. The larger the outer diameter of the first opening, the more smoothly the cable 200 enters the first opening. The smaller the inner diameter, the better the cable is limited.

[0076] As another example, the first opening includes opposite first and second side edges, wherein the first and / or second side edges are convexly curved or chamfered. The curved or chamfered side edges can reduce interference with the flat cable 200, allowing the flat cable 200 to smoothly pass through the curved or chamfered side edges into the first opening, and avoiding the risk of puncturing or scratching the flat cable.

[0077] In some embodiments, the flat cable arranging mechanism 20 further includes a second limiting assembly 22 located above the flat cable arranging assembly 21. The second limiting assembly 22 includes a limiting jaw and a second limiting drive 221. The limiting jaw is arranged at the driving end of the second limiting drive 221, and the second limiting drive 221 drives the limiting jaw to open or close. In the closed state of the limiting jaw, the limiting jaw has a second gap, and the connection segment of the flat cable 200 adjacent to the screen is limited in the second gap, and the free segment of the flat cable away from the screen is limited in the first gap.

[0078] The second limiting assembly 22 can be adjacent to the screen assembly pickup mechanism 10, and is used to limit the connection segment of the flat cable adjacent to the screen. The connection segment adjacent to the screen can be first limited in the second gap by the limiting jaw of the second limiting assembly 22, so as to stabilize the flat cable. Since the swing (wobble) amplitude of the flat cable adjacent to the screen is smaller, the clamping and limiting are easier, and the reliability of clamping and limiting the flat cable is improved. Then, the free segment away from the screen is limited in the first gap by the first limiting assembly 212, so that the upper and lower segments of the flat cable are both limited, the flat cable is more stable, the flat cable is more accurately inserted into the middle frame through hole, and the success rate of threading is improved.

[0079] As an example, the second limiting drive 221 is a second swing cylinder including a second fixed rod 222 and a second swing rod 223. The limiting jaw includes a second fixed plate 224 and a second movable plate 225, the second fixed plate 224 is arranged at the end of the second fixed rod 222, and the second movable plate 225 is arranged at the end of the second swing rod 223.

[0080] When the second swing rod 223 of the second swing cylinder moves close to the second fixed rod 222, the second movable plate 225 moves close to the second fixed plate 224 to the closed state, and the second gap is formed between the second fixed plate 224 and the second movable plate 225, the flat cable 200 is clamped and limited in the second gap, and the connection segment of the flat cable 200 is limited. When the second swing rod 223 of the second swing cylinder moves away from the second fixed rod 222, the second movable plate 225 moves away from the second fixed plate 224 to the open state, and the second fixed plate 224 and the second movable plate 225 release the clamping and limiting of the flat cable 200.

[0081] The driving mode of the second fixed plate 224 and the second movable plate 225 is not limited to the second swing cylinder pneumatic mode. In other embodiments, the second fixed plate 224 and the second movable plate 225 can also be driven by magnetism to open or close the second fixed plate 224 and the second movable plate 225. For example, the second limiting driving part 221 can include a third electromagnet arranged on the second fixed plate 224 and a fourth electromagnet arranged on the second movable plate 225, wherein the third electromagnet corresponds to the fourth electromagnet. By energizing the third electromagnet and the fourth electromagnet to change the magnetic pole, the second fixed plate 224 and the second movable plate 225 can be moved close to or away from each other to limit the wire clamp or contact the wire clamp.

[0082] The second limiting assembly further includes a second limiting block 226. The second limiting block 226 is arranged between the second fixed rod 222 and the second swing rod 223. When the second swing cylinder drives the limiting jaw to close, the second fixed rod 222 and the second swing rod 223 abut against the second limiting block 226, so that the second fixed plate 224 and the second movable plate 225 form a second gap, so that the connection section of the wire is not clamped.

[0083] By arranging the second limiting block 226 between the second fixed rod 222 and the second swing rod 223, the first gap can be formed when the second fixed plate 224 and the second movable plate 225 are closed, without changing the structure of the limiting part, and the installation is convenient.

[0084] For example, the second limiting block 226 can be detachably fixed to the second fixed rod 222 or the second swing rod 223. The second limiting block 226 can have the same structure as the first limiting block 217, and can include a mounting part and a limiting part protruding downward from the mounting part. The mounting part can be fixed to the upper part of the second fixed rod 222 or the second swing rod 223 by means of bolts, buckles or the like, so that the protruding limiting part is located between the second fixed rod 222 and the second swing rod 223.

[0085] When threading the short wire, the second limiting block 226 is detached, so that the second limiting assembly 22 can clamp the short wire in the closed state, so that the short wire is more stable and accurate during threading, thereby being suitable for threading the short wire into the corresponding through hole of the middle frame. Therefore, the screen assembly wire threading device 100 of the embodiment of the present disclosure, the second limiting block 226 is detachably fixed to the second fixed rod 222 or the second swing rod 223, and is suitable for long and short wires, and has good adaptability.

[0086] The first gap formed when the second fixed plate 224 and the second movable plate 225 are closed in the above embodiment is not limited to being achieved by the second limiting block 226. In the threading scenario for a long cable, the second limiting block 226 can not be needed. For example, corresponding recesses are formed on the opposite surfaces of the second fixed plate 224 and the second movable plate 225. When the first swing cylinder drives the second fixed plate 224 and the second movable plate 225 to close, the first gap is formed by the recesses on the opposite surfaces of the second fixed plate 224 and the second movable plate 225 to restrict the cable in the first gap.

[0087] In some embodiments, the second limiting assembly 22 further includes a second positioning block 227. The second positioning block 227 is fixed to the second fixed plate 224, and the second positioning block 227 is provided with a second opening facing the second movable plate 225, the second opening being used to accommodate a tail section of the cable; or the second positioning block 227 is fixed to the second movable plate 225, and the second positioning block 227 is provided with a second opening facing the second fixed plate 224, the second opening being used to accommodate a tail section of the cable.

[0088] The structure of the second positioning block 227 can be the same as that of the first positioning block 219. The second opening of the second positioning block 227 facilitates positioning of the cable to restrict displacement of the cable 200 in the front-rear direction, and the second fixed plate 224 and the second movable plate 225 restrict displacement of the cable 200 in the left-right direction, so that the cable 200 is restricted in the first gap in the front-rear and left-right directions, and the cable 200 is more stably kept corresponding to the through hole of the middle frame, the threading is more accurate, and the threading success rate is improved.

[0089] For example, the outer diameter of the second opening is greater than the inner diameter. During movement of the second movable plate 225 close to the second fixed plate 224, the cable 200 enters the second opening from the outer end to the inner end. The greater the outer diameter of the second opening, the more smoothly the cable 200 enters the first opening; and the smaller the inner diameter, the better the cable is positioned.

[0090] In another example, the second opening includes opposite third and fourth side edges, and the third and / or fourth side edges are outwardly convex arc-shaped edges or chamfered edges. The arc-shaped edges or chamfered edges can reduce interference with the cable 200, so that the cable 200 smoothly passes through the arc-shaped edges or chamfered edges to enter the second opening, and the risk of piercing and scratching the cable is also avoided, and the cable is better protected.

[0091] In some embodiments, the screen assembly passes through the cable arrangement 100 further comprises a driving mechanism 23 for driving the cable management assembly 21 and the second limiting assembly 22 to lift. The driving mechanism comprises a first lifting cylinder 231 and a second lifting cylinder 232. Among them, the first lifting cylinder 231 is connected with the moving mechanism 30, and the driving end of the first lifting cylinder 231 is connected with the second limiting assembly 22, and the second limiting assembly 22 is driven to lift. The second lifting cylinder 232 is connected with the driving end of the first lifting cylinder 231, and the driving end of the second lifting cylinder 232 is connected with the cable management assembly 21, and the cable management assembly 21 is driven to lift.

[0092] For example, the first lifting cylinder 231 can be connected with the moving mechanism 30 through the first connecting plate 234, and the second lifting cylinder 232 is fixed on the telescopic rod of the first lifting cylinder 231. At the same time, the second swing cylinder of the second limiting assembly 22 is fixed to the telescopic rod of the first lifting cylinder 231 through the second connecting plate 233. The first swing cylinder of the cable management assembly 21 is fixed to the telescopic rod of the second lifting cylinder 232.

[0093] The first lifting cylinder 231 of the driving mechanism 23 lifts to drive the second lifting cylinder 232 and the second limiting assembly 22 to lift together. Obviously, the cable management assembly 21 also lifts together with the second lifting cylinder 232. The second lifting cylinder 232 lifts to drive the cable management assembly 21 to lift, so as to move the cable clamping jaw and the limiting clamping jaw to the pre-clamping cable position to clamp and limit the cable.

[0094] Figure 3 It is a perspective view of a screen assembly pickup mechanism according to an exemplary embodiment. Figure 4 It is a side view of a screen assembly pickup mechanism according to an exemplary embodiment.

[0095] In some embodiments, as shown in Figure 3 and Figure 4 The screen assembly pickup mechanism 10 in the above embodiment can comprise a suction mechanism, which can comprise a suction plate 11 for sucking the screen with the cable. The suction plate 11 is connected with the moving mechanism 30, and the sucked screen is transported to the upper side of the middle frame through the moving mechanism 30. The shape of the suction plate 11 matches the shape of the screen, and a plurality of suction holes are arranged thereon to generate negative pressure for sucking the screen through the suction holes. The screen is easily picked up and released by the suction plate 11, and it is also convenient to control. Since the screen is relatively fragile, it is not necessary to make hard contact by suction, which can prevent the screen from being scratched and effectively protect the screen.

[0096] The screen assembly pickup mechanism 10 of the embodiments of the present disclosure is not limited to sucking the screen by the suction plate 11. In an example, the screen assembly pickup mechanism 10 can be a clamping assembly, which can include two clamping plates connected with the swing cylinder, and the two clamping plates are driven to move close to or away from each other to clamp or release the screen.

[0097] In some embodiments, as shown in Figure 3 and Figure 4 The screen assembly cable threading device 100 further includes an angle adjusting mechanism 12 connected with the suction plate 11 to drive the suction plate 11 to rotate to adjust the angle of the suction plate 11. When the screen assembly pickup mechanism 10 moves above the middle frame, it needs to be aligned with the middle frame, for example, the position of the screen and the position of the middle frame are obtained by a vision camera, and based on the position of the screen and the position of the middle frame, the angle of the suction plate 11 is adjusted by the angle adjusting mechanism 12 to align the screen with the cable sucked by the suction plate 11 with the middle frame. The angle adjusting mechanism 12 can more accurately align the screen with the middle frame, making it easier for the screen cable to pass through the through hole of the middle frame, and facilitating precise threading.

[0098] In some embodiments, the angle adjusting mechanism 12 can include a rotary motor 121, a reducer 122, and a rotating plate 123. The rotary motor 121 can be connected with the moving mechanism 30. The input end of the reducer 122 is connected with the rotating shaft of the rotary motor 121, the output end of the reducer 122 is connected with the rotating plate 123, and the suction plate 11 is connected with the rotating plate 123. When the suction plate 11 sucks the screen, or when the sucked screen needs to be aligned with the middle frame, the angle of the suction plate 11 needs to be adjusted. The rotary motor 121 is rotated to drive the reducer 122 to rotate the rotating plate 123 and the screen to align the suction plate 11 with the screen, or to align the sucked screen with the middle frame. The reducer 122 can be a harmonic reducer, which can improve the rotation accuracy of the suction plate 11 and make the alignment of the middle frame and the screen more accurate.

[0099] In some embodiments, as shown in Figure 2 The screen assembly cable threading device 100 further includes a buffer assembly arranged between the suction plate 11 and the rotating plate 123. After the screen cable passes through the through hole of the middle frame, the screen needs to be assembled on the middle frame. The moving mechanism 30 can be used to press down the screen assembly pickup mechanism 10, so that the suction plate 11 moves up and down relative to the rotating plate 123, and the buffer assembly is compressed to buffer the screen when it is pressed onto the middle frame. By arranging the buffer assembly between the suction plate 11 and the rotating plate 123, the buffer assembly can buffer the screen when it is pressed onto the middle frame, preventing the screen from being broken due to excessive pressing, and improving the reliability of the screen assembly on the middle frame. The buffer assembly can be a spring or an elastic rubber pad. Similarly, the buffer assembly also plays a buffering role when the suction plate 11 sucks the screen.

[0100] In some embodiments, the screen assembly passes through the cable device 100, and the suction plate 11 is connected to the rotating plate 123 through the guide assembly. The guide assembly plays a guiding role in the buffering process of the suction plate 11 moving up and down relative to the rotating plate 123, that is, the screen being pressed to the middle frame, so that the buffering process is more stable, and the precision of the screen being pressed to the middle frame is ensured.

[0101] In an example, the guide assembly can include a guide rail 124 and a sliding block 125. The guide rail 124 is arranged on the rotating plate 123, for example, the rotating plate 123 is in an inverted L shape, including a horizontal connecting part and a vertical connecting part, and the guide rail 124 is vertically arranged on the vertical connecting part. A fixed plate 129 is arranged on the upper part of the suction plate 11. The fixed plate 129 can be in an inverted T shape, including a horizontal fixed part and a vertical fixed part. The horizontal fixed part is fixed on the upper surface of the suction plate 11, and the vertical fixed part is fixed on the sliding block 125. A limiting block is further arranged on the vertical connecting part towards the sliding block, to prevent the sliding block from disengaging from the guide rail 124.

[0102] The buffering assembly can include a buffering spring 126, a pressing plate 127, and a sliding rod 128. One end of the sliding rod 128 is vertically fixed on the fixed plate, and a through hole corresponding to the sliding rod 128 is arranged on the rotating plate 123, for the other end of the sliding rod 128 to pass through. The pressing plate 127 is slidably sleeved on the sliding rod 128, and the spring 126 is sleeved on the sliding rod 128 and located between the pressing plate 127 and the rotating plate 123. In the initial state, the spring is in a natural state. The moving mechanism 30 moves downward to drive the screen on the suction plate 11 to contact the middle frame. The moving mechanism 30 continues to move downward, at which time the spring is compressed, buffering the moving mechanism 30 and the suction plate 11. Continue to move downward to press the screen to the middle frame.

[0103] The above-mentioned guide assembly is not limited to the sliding block and the sliding rail. In another example, the guide assembly can also be a guide rod and a sliding block assembly, which plays a role in smoothly guiding the screen to be pressed to the middle frame. In yet another example, the guide assembly can also be a guide groove and a guide block (guide rod) assembly, which plays a role in smoothly guiding the screen to be pressed to the middle frame.

[0104] In some embodiments, the moving mechanism 30 described above can be a three-axis moving mechanism, for example, comprising a Y-axis moving assembly 31, an X-axis moving assembly 32, and a lifting assembly 33. The X-axis moving assembly 32 is connected with the Y-axis moving assembly 31; the lifting assembly 33 is connected with the X-axis moving assembly 32; and the screen component picking mechanism 10 and the wire arranging mechanism 20 are both connected with the lifting assembly 33. The Y-axis moving assembly 31 drives the X-axis moving assembly 32, the lifting assembly 33, the screen component picking mechanism 10, and the wire arranging mechanism 20 to move together along the Y-axis direction; the X-axis moving assembly 32 drives the lifting assembly 33, the screen component picking mechanism 10, and the wire arranging mechanism 20 to move together along the X-axis direction perpendicular to the Y-axis direction; and the lifting assembly 33 moves the screen component picking mechanism 10 and the wire arranging mechanism 20 together.

[0105] By moving the screen component picking mechanism 10 and the wire arranging mechanism 20 on three axes through the moving mechanism 30, the conveying of the screen, the wire arranging and threading of the screen, and the screen pressing operation are automatically completed, the flexibility is greatly improved, the entire threading and pressing operation does not need manual participation, the efficiency is improved, and the labor cost is saved.

[0106] The Y-axis moving assembly 31 can comprise a moving plate 311, a Y-axis driving motor (not shown in the figure), and a Y-axis lead screw (not shown in the figure) arranged along the Y-axis direction, a nut being threadedly connected to the Y-axis lead screw, the moving plate 311 being connected with the Y-axis lead screw through the nut, the Y-axis driving motor rotating to drive the Y-axis lead screw to rotate, and driving the moving plate 311 to move along the Y-axis direction to drive the entire screen component threading device 100 to move along the Y-axis direction. The Y-axis moving assembly 31 of the present disclosure is not limited to the motor lead screw nut assembly driving the moving plate 311 to move along the Y-axis direction, and in another example, the moving plate 311 can be driven to move along the Y-axis direction through a pneumatic cylinder.

[0107] The X-axis moving assembly 32 can comprise an X-axis driving motor 321, a first adapter plate 322, and a moving block 323. The X-axis driving motor 321 is fixed on the moving plate 311 through a fixing seat, the output end of the X-axis driving motor 321 is provided with the moving block 323 through a speed reducer, the moving block 323 is slidingly connected with a slide rail extending along the X-axis direction arranged on the fixing seat, and the first adapter plate 322 is fixed on the moving block 323. The X-axis driving motor 321 rotates to drive the moving block 323 to slide along the X-axis on the slide rail, and drive the first adapter plate 322 to move along the X-axis direction. The X-axis moving assembly 32 of the present disclosure is not limited to the motor lead screw nut assembly driving the first adapter plate 322 to move along the X-axis direction, and in another example, the first adapter plate 322 can be driven to move along the Y-axis direction through a pneumatic cylinder.

[0108] The lifting assembly 33 may include a lifting cylinder 331 and a second adapter plate 332 fixed to the drive end of the lifting cylinder 331. The lifting cylinder 331 is fixed to the first adapter plate 322, and the screen assembly pickup mechanism 10 and the cable management mechanism 20 are both fixed to the second adapter plate 332. The drive end of the lifting cylinder 331 drives the second adapter plate 332 to move up and down, and the screen assembly pickup mechanism 10 and the cable management mechanism 20 follow the up and down movement of the second adapter plate 332. The lifting assembly 33 disclosed herein is not limited to being driven by the lifting cylinder 331; it can also be driven by a motor in conjunction with a screw and nut assembly to move the second adapter plate 332 up and down.

[0109] The aforementioned moving mechanism 30 is not limited to the structure described above. In other embodiments, the moving mechanism 30 may be a robotic arm, and is not limited to three-axis movement. The robotic arm may be multi-axis movement, such as a three-axis or four-axis robotic arm.

[0110] Figure 6 This is a schematic diagram of the structure of a support fixture according to an exemplary embodiment.

[0111] like Figure 1 and Figure 6 As shown, in some embodiments, the screen assembly cable threading device 100 of this disclosure may further include a support fixture 40, located below the screen assembly picking mechanism 10, for supporting the middle frame. The support fixture 40 may include a base 41 and a support platform 42 disposed on the base 41. The shape and size of the support platform 42 may be adapted to the middle frame for placing the middle frame. By supporting the middle frame with the support fixture 40 and limiting the middle frame, displacement of the middle frame during cable threading and screen pressing can be prevented, thus avoiding interference with cable threading and assembly.

[0112] In some embodiments, the screen component cable threading device 100 disclosed herein further includes a stop 44, which is fixedly disposed on the support platform 42. After the screen cable hits the stop 44, it bends and the bent cable passes through the through hole in the middle frame.

[0113] The screen assembly pickup mechanism 10, which picks up the screen, can be moved above the support fixture 40 by the moving mechanism 30, causing the screen's ribbon cable to hit the stop block 44 and bend downwards. Then, after the ribbon cable management mechanism 20 removes the first limiting block 217 and the second limiting block 226, it clamps the bent ribbon cable. Next, the moving mechanism 30 drives the ribbon cable management mechanism 20 to move downwards, inserting the bent ribbon cable clamped by the ribbon cable management mechanism 20 into the through hole of the middle frame. However, it is not limited to this; it is also possible to directly insert the bent ribbon cable into the through hole of the middle frame by moving the screen assembly pickup mechanism 10 downwards without the ribbon cable management mechanism 20 clamping the bent ribbon cable.

[0114] When the screen cable is short, the screen cable is in a substantially parallel state with the screen, and the self-weight and length of the screen cable cannot make it naturally bend. Thus, it is difficult to automatically pass the screen cable through the middle frame located below the screen, and the screen cable needs to be pre-bent. The present disclosure provides a stop block 44, which makes the screen cable first impact and bend, and then be clamped and passed, or directly pass the bent screen cable. The bent screen cable is convenient to clamp and pass through the through hole of the middle frame. The automatic passing of the screen cable of a short length is realized, and the passing efficiency and accuracy are greatly improved.

[0115] In some embodiments, the bearing table 42 is provided with an avoidance space 43 corresponding to the through hole of the middle frame, which is used to accommodate the screen cable passing through the middle frame, so as to smoothly pass through the middle frame and avoid interference between the screen cable and the bearing table 42 affecting the passing of the screen cable.

[0116] However, the bearing table 42 can also not be provided with the avoidance space 43. When the middle frame is placed on the bearing table 42, the through hole of the middle frame can be made to protrude out of the bearing table 42, so that the part of the middle frame with the through hole is suspended, facilitating the passing of the screen cable through the through hole.

[0117] In some embodiments, the bearing table 42 is provided with a detection component in the avoidance space, which is used to detect whether the screen cable has passed through the through hole. The detection component can be a photoelectric sensor. If the detection component detects that the screen cable has passed into the through hole, the clamping jaw of the clamping mechanism is opened to separate from the screen cable, and then the screen pressing operation is performed. If the detection result is that the screen cable has not passed into the through hole, the screen and the middle frame can be re-aligned, and after re-alignment, the passing operation is performed again by driving the screen cable arranging mechanism 20 to move downward by the moving mechanism 30.

[0118] In some embodiments, the stop block 44 includes a horizontal stop rod 441 and a connecting rod 442. One end of the connecting rod 442 is connected to the bearing table 42, and the other end extends upward and is connected to the horizontal stop rod 441. The horizontal stop rod 441 is used to bend the screen cable when it is impacted. The horizontal stop rod 441 is connected by the connecting rod 442, so that the horizontal stop rod 441 is higher than the bearing table 42, and a gap is formed between the horizontal stop rod 441 and the bearing table 42. The gap can facilitate the clamping jaw of the screen cable arranging mechanism 20 to pass through, and facilitate the clamping of the bent screen cable. By adjusting the size of the horizontal stop rod 441, the contact area when the screen cable is impacted can be adjusted, which can protect the screen cable from being scratched or pierced, and also make the screen cable easier to bend.

[0119] In some embodiments, the connecting rod 442 is fixed to the side of the bearing table 42 adjacent to the avoiding space 43. For example, the connecting rod 442 can be located on the long side or the short side of the bearing table 42, so as to correspond to the position of the screen wire, ensure that the screen wire is located at the pre-clamping position after being bent by the horizontal blocking rod 441, and ensure that the wire clamping mechanism 20 completes the clamping of the screen wire, so that the screen wire can be clamped more accurately and efficiently, and the wire clamping precision is improved.

[0120] Figure 7 A flowchart of a screen assembly wire clamping method according to an exemplary embodiment is shown.

[0121] As shown in Figure 7 According to the embodiments of the present disclosure, a screen assembly wire clamping method 300 is also provided, which is applied to the screen assembly wire clamping device 100 of any of the above-mentioned embodiments. The screen assembly wire clamping method 300 comprises steps S11, S12 and S13.

[0122] In step S11, the screen with the wire is picked up by the screen assembly picking mechanism 10.

[0123] The screen assembly picking mechanism 10 can be a suction mechanism or a clamping mechanism, which picks up the screen with the wire by suction or clamps the screen with the wire.

[0124] In step S12, the wire is clamped and positioned by the wire arranging mechanism 20.

[0125] In step S13, the screen assembly picking mechanism 10 and the wire arranging mechanism 20 are driven to move by the moving mechanism 30, and the clamped and positioned wire is clamped into the through hole of the middle frame.

[0126] The screen assembly picking mechanism 10 picking up the screen is driven to move to the upper side of the middle frame by the moving mechanism 30, so that the wire of the screen corresponds to the through hole of the middle frame, then the wire is clamped and positioned by the wire arranging mechanism 20, and the clamped and positioned wire is clamped into the through hole by driving the wire arranging mechanism 20 to move downward by the moving mechanism 30.

[0127] After the screen assembly picking mechanism 10 picks up the screen with the wire, the wire of the screen is clamped and positioned by the wire arranging mechanism 20, then the screen assembly picking mechanism 10 and the wire arranging mechanism 20 are driven to move to the upper side of the middle frame by the moving mechanism 30, so that the wire of the screen corresponds to the through hole of the middle frame, then the wire is clamped into the through hole by driving the wire arranging mechanism 20 to move downward by the moving mechanism 30 during the movement of the screen.

[0128] In the prior art, when threading a long screen cable, the long cable will sway and the sway range is large, and the cable is very unstable, so the cable and the through hole of the middle frame cannot always be in alignment, resulting in a low threading success rate. In addition, the long cable will bend, and the positions of the cable segments deviate greatly from the position of the through hole of the middle frame, and cannot be aligned, resulting in threading difficulty.

[0129] The screen assembly cable threading method 300 of the embodiment of the present disclosure clamps and limits the cable within a certain space range through the cable arrangement mechanism 20, prevents the screen cable from swaying, and in addition, limits the bending degree of the cable, so that the clamped and limited cable and the through hole of the middle frame can be within a corresponding range (in alignment) during the cable threading process, so that the cable threading success rate can be greatly improved, the cable threading is more accurate, and the cable threading efficiency is also improved.

[0130] In an embodiment, the screen assembly cable threading device 100 further comprises a driving mechanism;

[0131] Step S12 comprises: moving the cable arrangement mechanism 20 to a pre-clamping cable position by the driving mechanism 23, and clamping the cable at the pre-clamping cable position by the cable arrangement mechanism 20.

[0132] In the process of picking up the screen with the cable by the screen assembly picking mechanism 10, the cable arrangement mechanism 20 needs to avoid the screen assembly picking mechanism 10 to avoid interference. After the screen assembly picking mechanism 10 picks up the screen, the cable arrangement mechanism 20 is moved to a preset clamping cable position corresponding to the position of the screen cable by the driving mechanism 23, so that the cable arrangement mechanism 20 can accurately clamp and limit the cable at the pre-clamping cable position.

[0133] But not limited to this, the position of the cable can also be obtained by a visual mechanism, and the cable is clamped and limited by the cable arrangement mechanism 20 based on the obtained position of the cable.

[0134] In an embodiment, the cable arrangement mechanism 20 comprises a cable arrangement assembly 21 and a second limiting assembly 22. The cable arrangement mechanism 20 limits the cable at the pre-clamping cable position, comprising: limiting the adjacent screen connecting segment of the cable by the cable arrangement assembly 21, and limiting the free segment of the cable away from the screen by the second limiting assembly 22.

[0135] Since the closer the position of the wire to the screen, the smaller the swing (shake) amplitude, the easier the clamping limit is, so the connecting segment adjacent to the screen can be first limited in the second gap by the limiting clamping jaw of the second limiting assembly 22 to stabilize the wire and improve the reliability of clamping and limiting the wire. Then, the free segment away from the screen is limited in the first gap by the first limiting assembly 212, so that the upper and lower two segments of the wire are both limited, the wire is more stable, the wire is more accurately inserted into the through hole of the middle frame, and the success rate of threading is improved.

[0136] In an embodiment, the wire arranging mechanism 20 further includes a clamping jaw assembly 218. The wire to be clamped and limited is straightened by the clamping jaw assembly 218.

[0137] The free segment of the wire 200 needs to be aligned with the through hole corresponding to the middle frame so that the wire can smoothly pass through the through hole corresponding to the middle frame. Since the long free segment of the wire 200 is easy to bend, the wire 200 free segment is straightened downward by the wire straightening clamping jaw 2181 of the clamping jaw assembly 218, so that the wire 200 free segment is directed towards the through hole of the middle frame, so as to more accurately insert the wire 200 into the through hole.

[0138] In an embodiment, step S13 includes: driving the wire arranging mechanism 20 to descend by the moving mechanism 30, and threading the wire located below the clamping jaw assembly 218 into the through hole corresponding to the middle frame. Then, the free segment of the wire 200 is released by the clamping jaw assembly 218 and the first limiting assembly 212; then, the wire arranging mechanism 20 is continuously driven to descend by the moving mechanism 30, and the wire located below the second limiting assembly 22 is threaded into the through hole corresponding to the middle frame. Then, the connecting segment of the wire 200 is released by the second limiting assembly 22; the connecting segment of the wire 200 is threaded into the through hole corresponding to the middle frame by continuously descending by the moving mechanism 30.

[0139] The long wire 200 is limited in two segments, and is threaded into the through hole corresponding to the middle frame in three segments, which reduces the swing of the long wire 200, improves the accuracy of threading the wire, and improves the efficiency of threading the wire.

[0140] In some embodiments, the screen assembly wire threading method 300 further includes: moving the screen assembly picking mechanism 10 by the moving mechanism 30 to assemble the screen on the middle frame.

[0141] The screen can be pressed on the middle frame by the moving mechanism 30 after detecting that the wire has been threaded into the through hole of the middle frame.

[0142] In an embodiment, the screen assembly wire threading method 300 further includes: detecting whether the wire is threaded into the through hole of the middle frame, and if the detection result is that the wire is threaded into the through hole, releasing the wire by the wire arranging mechanism 20.

[0143] The optical sensor can detect whether the flat cable is inserted into the middle frame. If the optical sensor detects that the flat cable is inserted into the through hole, the clamping mechanism is separated from the flat cable and returns to the initial position, and then the screen pressing operation can be performed. If the detection result is that the flat cable is not inserted into the through hole, the screen and the middle frame can be aligned again, and after the alignment, the flat cable is inserted again by driving the flat cable arrangement mechanism 20 to move downward by the moving mechanism 30.

[0144] By detecting whether the flat cable is inserted into the through hole of the middle frame, it can be ensured that each screen flat cable is inserted into the through hole before pressing the screen, preventing the possibility of the flat cable being bent and broken when the screen is pressed against the middle frame, thereby improving the reliability of the flat cable insertion.

[0145] In some embodiments, the screen assembly flat cable insertion method 300 further comprises aligning the screen and the middle frame.

[0146] In an example, the screen assembly flat cable insertion device 100 further comprises an angle adjusting mechanism, and aligning the screen and the middle frame comprises: acquiring the position of the screen and the position of the middle frame by the visual mechanism, adjusting the angle of the suction mechanism by the angle adjusting mechanism based on the position of the screen and the position of the middle frame, and aligning the screen and the middle frame.

[0147] Adjusting the angle of the screen assembly pickup mechanism by the angle adjusting mechanism to align the screen and the middle frame can make the alignment more accurate and improve the flat cable insertion accuracy and screen pressing accuracy.
