[0068] Figure 1 A schematic structural diagram of a display screen processing production line provided by an embodiment of the present invention is shown. Figure 2 FIG. 1 is a top view schematic diagram of a display screen processing production line provided by an embodiment of the present invention. Figure 1-Figure 2 As shown, this embodiment provides a display processing production line, which includes a foam laminating device 100, a bending device 200 and an intermediate transmission device 300; the foam laminating device 100 is configured to carry the screen body to be attached and can attach the foam to the screen body to be attached to form a semi-finished product, and an FPC board is connected to one side of the screen body to be attached; the intermediate transmission device 300 is configured to transfer the semi-finished product on the foam laminating device 100 to the bending device 200; the bending device 200 is configured to bend the FPC board relative to the semi-finished product according to a preset path to form a finished product. Through the mutual cooperation between the foam laminating device 100, the bending device 200 and the intermediate transmission device 300, the automatic laminating between the foam and the screen body and the automatic bending of the FPC board can be realized, which reduces the workload of operators, reduces labor costs, and can improve work efficiency and the yield rate of finished products.

[0069] It should be noted that, in the present embodiment, the screen body to be attached may be a display screen of an electronic product such as a mobile phone touch screen or a tablet computer display screen.

[0070] Preferably, the display processing line further includes a base 700, on which the foam laminating device 100, the bending device 200 and the intermediate transmission device 300 are all arranged, and the base 700 plays the role of overall support. For the convenience of description, the length direction of the base 700 is defined as the X direction, the width direction of the base 700 is defined as the Y direction, and the height direction of the base 700 is defined as the Z direction, wherein the X direction, the Y direction and the Z direction are three directions perpendicular to each other, and have no practical meaning.

[0071] Furthermore, the display screen processing production line further includes a feeding device 400 and a loading device 500, wherein the feeding device 400 is configured to supply the screen to be attached; and the loading device 500 is configured to transfer the screen to be attached carried by the feeding device 400 to the foam laminating device 100. By providing the feeding device 400 and the loading device 500, the automatic loading operation of the screen to be attached can be realized, and the operator can load the screen to be attached at a position away from the foam laminating device 100, thereby preventing the operator from being injured during the foam laminating process at the foam laminating device 100; and when the operator loads the material, the foam laminating device 100 does not need to stop to wait for the material, which further improves the production efficiency of the display screen production line.

[0072] Figure 3 It shows a schematic structural diagram of a screen loading mechanism 401 and a screen unloading mechanism 402 provided in an embodiment of the present invention. Figure 4 A schematic structural diagram of a tray transfer mechanism 403 provided in an embodiment of the present invention is shown. Figure 5 FIG. 4 is a schematic diagram showing the structure of a screen feeding mechanism 401 provided in an embodiment of the present invention. Figure 3-Figure 5 Combined with Figure 1 As shown, the feeding device 400 includes a screen loading mechanism 401, a screen unloading mechanism 402 and a tray transfer mechanism 403. The screen loading mechanism 401 and the screen unloading mechanism 402 are arranged side by side. The screen loading mechanism 401 can carry a plurality of loading trays filled with screens to be attached and stacked in sequence along the vertical direction; the screen unloading mechanism 402 can carry a plurality of empty loading trays stacked in sequence along the vertical direction, and the tray transfer mechanism 403 is configured to transfer the empty loading tray located on the top layer of the screen loading mechanism 401 to the screen unloading mechanism 402, thereby realizing the automatic transfer of the empty loading trays, so that the operator can load a plurality of screens to be attached at one time, thereby reducing the number of loading times and improving the loading efficiency.

[0073] Optionally, a plurality of receiving slots arranged in an array are provided on the carrier tray, and each receiving slot can carry a screen to be attached, so that a plurality of screens to be attached can be accommodated on one carrier tray, further increasing the number of screens to be attached that the operator can load each time. This embodiment does not limit the number of receiving slots on the carrier tray, and can be adjusted according to the size of the carrier tray and the size of the screen to be attached.

[0074] Optionally, the shape of the receiving groove is adapted to the outer contour of the corresponding screen body to be attached, that is, the outer wall of the screen body to be attached can fit with the inner wall of the receiving groove, thereby achieving stable accommodation and precise positioning of the screen body to be attached.

[0075] The working process of the feeding device 400 is as follows: the operator manually places multiple supporting trays filled with screens to be attached and stacked in sequence along the vertical direction on the screen loading mechanism 401, and the loading device 500 sequentially grabs the screens to be attached in the supporting tray on the top layer of the screen loading mechanism 401 and transfers them to the foam laminating device 100; when all the screens to be attached in the supporting tray on the top layer are transferred, the tray transfer mechanism 403 grabs the empty supporting tray on the top layer and transfers it to the screen unloading mechanism 402; when the empty supporting trays on the screen unloading mechanism 402 are stacked to a preset number, the operator takes away multiple empty supporting trays stacked in sequence along the vertical direction at one time.

[0076] Further, the tray transfer mechanism 403 includes a tray transfer bracket 4034, a tray transverse drive assembly 4031, a tray lifting drive assembly 4032 and a tray adsorption assembly 4033; the tray transfer bracket 4034 is arranged on the base 700, and the tray transverse drive assembly 4031 is arranged on the tray transfer bracket 4034; the tray lifting drive assembly 4032 is connected to the output end of the tray transverse drive assembly 4031 to move in the horizontal direction under the driving action of the tray transverse drive assembly 4031; the tray adsorption assembly 4033 is connected to the output end of the tray lifting drive assembly 4032 to move in the vertical direction under the driving action of the tray lifting drive assembly 4032, and the tray adsorption assembly 4033 can adsorb the empty load-bearing tray on the screen feeding mechanism 401. Through the mutual cooperation between the tray transverse drive assembly 4031 and the tray lifting drive assembly 4032, the movement of the tray adsorption assembly 4033 in the transverse and longitudinal directions can be realized, thereby realizing the transfer of the empty load-bearing tray located at the top layer of the screen feeding mechanism 401.

[0077] In this embodiment, the tray transverse drive assembly 4031 is specifically a transverse drive linear motor; the tray lifting drive assembly 4032 is specifically a drive cylinder. Of course, in other embodiments, the tray transverse drive assembly 4031 and the tray lifting drive assembly 4032 can also adopt other drive structures with linear drive functions, which can also achieve the above effect.

[0078] Furthermore, the tray adsorption component 4033 includes a tray adsorption carrier and a first suction nozzle, the tray adsorption carrier is connected to the output end of the tray lifting drive component 4032, and the first suction nozzle is arranged on the tray adsorption carrier, and the first suction nozzle can use the negative pressure to tightly adsorb the carrying tray. Optionally, there are multiple first suction nozzles, and the multiple first suction nozzles are arranged in an array on the tray adsorption carrier. Multiple first suction nozzles adsorb the carrying tray at the same time, which can increase the adsorption area and improve the adsorption effect.

[0079] It should be noted that the specific structure of the screen loading mechanism 401 is the same as the specific structure of the screen unloading mechanism 402. This embodiment takes the screen loading mechanism 401 as an example to introduce the specific structures of the screen loading mechanism 401 and the screen unloading mechanism 402 in detail.

[0080] Specifically, the screen loading mechanism 401 includes a loading support frame 4011, a lifting frame 4012 and a telescopic tray-dividing member 4015. The lifting frame 4012 and the telescopic tray-dividing member 4015 are both arranged on the loading support frame 4011, and at least one of the two can move in the vertical direction relative to the loading support frame 4011. The lifting frame 4012 can carry a plurality of load trays stacked in sequence in the vertical direction, and the tray-dividing end of the telescopic tray-dividing member 4015 can extend in the horizontal direction and extend into the gap between the two load trays located at the top layer. By setting the telescopic tray-dividing member 4015, when the tray transfer mechanism 403 needs to transfer the empty load tray located at the top layer on the screen loading mechanism 401, the tray-dividing end of the telescopic tray-dividing member 4015 can extend and be located in the gap between the two load trays at the top layer, thereby pressing the load trays located at the second layer and below, so that the tray transfer mechanism 403 can only transfer one load tray at a time, thereby improving the accuracy of grabbing the load tray. In this embodiment, the telescopic disc-dividing member 4015 is a disc-dividing cylinder, and the output end of the disc-dividing cylinder is the above-mentioned disc-dividing end, which has a simple structure, is easy to install, and has a low manufacturing cost.

[0081] Optionally, a tray-dividing notch is provided at the bottom of the carrying tray, and the tray-dividing end of the telescopic tray-dividing member 4015 can extend into the tray-dividing notch of the carrying tray. This arrangement can provide sufficient insertion space for the tray-dividing end of the telescopic tray-dividing member 4015.

[0082] Optionally, at least one telescopic tray dividing member 4015 is provided on opposite sides of the loading support frame 4011. With this arrangement, both sides of the load-bearing tray can be pressed by the telescopic tray dividing member 4015, further ensuring that the tray transfer mechanism 403 can only transfer one load-bearing tray at a time.

[0083] Furthermore, the screen loading mechanism 401 further includes a screen lifting drive assembly 4013, which is disposed on the loading support frame 4011, and is configured to drive the lifting frame 4012 to move in the vertical direction. Specifically, after the tray transfer mechanism 403 transfers the empty load tray located at the top layer of the screen loading mechanism 401 to the screen unloading mechanism 402, the screen lifting drive assembly 4013 can drive the lifting frame 4012 to move upward by a distance of the thickness of the load tray, so that the loading device 500 can grab the corresponding screen to be attached at the same height each time, simplifying the material picking stroke of the loading device 500.

[0084] In this embodiment, the screen lifting drive assembly 4013 is a motor plus a lead screw nut pair. In other embodiments, the screen lifting drive assembly 4013 can also use a cylinder, a motor plus a gear rack, or a motor plus a gear chain, etc. to achieve the above effect. This embodiment does not limit the structure of the screen lifting drive assembly 4013. As long as the screen lifting drive assembly 4013 can drive the lifting frame 4012 to rise and fall, it is within the protection scope of this embodiment.

[0085] Furthermore, a position detection member is also provided on the loading support frame 4011, and the position detection member is used to detect whether the load tray located at the uppermost layer is at a preset height. Specifically, the screen lifting drive assembly 4013 is in communication connection with the position detection member, and when the position detection member detects that the load tray located at the uppermost layer is at a preset height, the screen lifting drive assembly 4013 stops the action. In this embodiment, the position detection member is specifically a proximity switch.

[0086] Of course, in other embodiments, the output end of the screen lifting drive assembly 4013 can also be connected to the telescopic tray-dividing member 4015 to drive the telescopic tray-dividing member 4015 to move in the vertical direction. At this time, the lifting frame 4012 is fixed on the loading support frame 4011. When the tray transfer mechanism 403 transfers the empty load tray on the top layer of the screen loading mechanism 401 to the screen unloading mechanism 402, the screen lifting drive assembly 4013 can drive the telescopic tray-dividing member 4015 to move downward in the vertical direction by a distance of the thickness of the load tray, so that the tray-dividing end of the telescopic tray-dividing member 4015 can be aligned with the gap between the two load trays on the top layer.

[0087] Furthermore, the loading support frame 4011 is provided with a first guide rail, the first guide rail extends in the vertical direction, and the lifting frame 4012 is provided with a first guide slider, the first guide slider is slidably matched with the first guide rail to ensure the stability when the lifting frame 4012 and the loading support frame 4011 slide relative to each other. Of course, the first guide rail can also be provided on the lifting frame 4012, and the first guide slider can be provided on the loading support frame 4011, and the above-mentioned effect can also be achieved.

[0088] Furthermore, the screen loading mechanism 401 also includes a material changing component 4014, which includes two material changing racks, which are respectively located on both sides of the lifting frame 4012, and the material changing racks can receive the load trays, and the two material changing racks are respectively slidably arranged on the side walls of the corresponding sides of the loading support frame 4011. When all the load trays on the screen loading mechanism 401 are transferred to the screen unloading mechanism 402, the operator can pull out the two material changing racks of the screen loading mechanism 401, and then place multiple stacked load trays filled with screens to be attached on the material changing racks, and then push the material changing racks into the loading support frame 4011; at this time, the screen lifting drive component 4013 drives the lifting frame 4012 to move upward, so as to receive multiple load trays. At the same time, the operator also needs to pull out the two material changing racks of the screen unloading mechanism 402, and then take away the multiple stacked empty load trays thereon, so as to complete a loading operation.

[0089] In order to ensure the stability of the sliding process of the material changing rack relative to the material loading support frame 4011, a second guide rail extending in the horizontal direction is provided on the material loading support frame 4011, and a second guide slider is provided on the material changing rack, and the second guide slider is slidably matched with the second guide rail. Of course, in other embodiments, the second guide rail can also be provided on the material changing rack, and the second guide slider can be provided on the material loading support frame 4011, which can also achieve the above effect.

[0090] Optionally, a limiting member is also provided on the loading support frame 4011 to limit the sliding movement of the material changing frame relative to the loading support frame 4011 to prevent the material changing frame from slipping off the loading support frame 4011 .

[0091] Furthermore, the material changing assembly 4014 also includes a material changing handle, and the two ends of the material changing handle are respectively connected to the two material changing racks. By providing the material changing handle, the operator can pull the material changing handle to pull out or push in the two material changing racks, which is convenient and quick to operate.

[0092] It should be particularly noted that the difference between the screen unloading mechanism 402 and the screen loading mechanism 401 is that the screen unloading mechanism 402 is used to carry multiple empty loading trays stacked in sequence along the vertical direction. When the tray transfer mechanism 403 transfers the empty loading tray on the screen loading mechanism 401 to the screen unloading mechanism 402, the lifting frame 4012 of the screen unloading mechanism 402 will move downward by a distance of the thickness of the loading tray to facilitate the re-transfer of the empty loading tray; in addition, the telescopic tray dividing member 4015 provided on the screen unloading mechanism 402 is used to realize the positioning of the empty loading tray to prevent a large offset in the relative position between two adjacent empty loading trays, which may cause the empty loading tray to collapse when the operator takes it.

[0132] Furthermore, the bearing mechanism 1 further includes a bearing rotation driving assembly 13, which is disposed on the base 700, and an output end of the bearing rotation driving assembly 13 is connected to the bearing turntable 11 to drive the bearing turntable 11 to rotate. In this embodiment, the bearing rotation driving assembly 13 is specifically a bearing rotation motor.

[0133] Furthermore, if Fig.15 As shown, the foam feeding mechanism 3 includes a feeding base 31, a foam winding roller 32, a first bottom film receiving roller 33, a second bottom film receiving roller 34 and a material receiving sliding plate 35. The feeding base 31 is arranged on the base 700, and the foam winding roller 32, the first bottom film receiving roller 33 and the second bottom film receiving roller 34 are all rotatably arranged on the feeding base 31. The foam winding roller 32 is used to wind the foam component. The foam component includes foam, a first bottom film and a second bottom film. The first bottom film and the second bottom film are respectively Attached to both sides of the foam, the first bottom film receiving roller 33 is used to roll up the first bottom film, the second bottom film receiving roller 34 is used to roll up the second bottom film, and the material receiving sliding plate 35 is slidably set on the feeding base 31 to transfer between the receiving station and the feeding station. When the material receiving sliding plate 35 slides to the receiving station, it can receive the foam after being separated from the first bottom film and the second bottom film; when the material receiving sliding plate 35 slides to the feeding station, it can facilitate the foam bonding mechanism 4 to grab the foam carried thereon.

[0134] Optionally, a plurality of material receiving adsorption holes arranged in an array are provided on the material receiving sliding plate 35, and the material receiving sliding plate 35 adsorbs corresponding foams through the material receiving adsorption holes to prevent the foams from falling when the material receiving sliding plate 35 slides from the receiving station to the feeding station.

[0135] Furthermore, a stripping piece is also provided on the material receiving sliding plate 35, and the stripping piece can strip the foam from the first bottom film to prevent the foam from being rolled up onto the first bottom film receiving roller 33 along with the first bottom film. Optionally, the thickness of the stripping piece gradually decreases toward the first bottom film receiving roller 33 to facilitate the insertion of the end of the stripping piece between the foam and the first bottom film to separate the two. Optionally, the number of the stripping pieces is at least two to achieve uniform and rapid separation of the foam and the first bottom film.

[0136] Since the foam is light, the foam separated from the first bottom film and the second bottom film is easy to fold. In order to avoid this phenomenon, the foam feeding mechanism 3 also includes a pressing component 36, which includes a pressing cylinder and a pressing plate. The pressing cylinder is arranged on the feeding base 31, and the output end of the pressing cylinder is connected to the pressing plate to drive the pressing plate to move in the vertical direction. When the material-carrying sliding plate 35 slides between the receiving station and the feeding station, the pressing cylinder drives the pressing plate to move upward to avoid the material-carrying sliding plate 35; when the material-carrying sliding plate 35 is located at the receiving station, the pressing cylinder drives the pressing plate to move downward so that the foam falls flat on the material-carrying sliding plate 35.

[0137] Optionally, at least one tensioning roller 37 is rotatably arranged between the foam winding roller 32 and the first bottom film receiving roller 33 and between the foam winding roller 32 and the second bottom film receiving roller 34, so that the foam component is always kept in a taut state during the transmission process, thereby improving the working stability of the foam feeding mechanism 3.

[0138] Furthermore, the material feeding base 31 includes a first support seat 311 and a second support seat 312, wherein the first support seat 311 is fixed on the base 700, and the second support seat 312 is slidably arranged on the first support seat 311, and the foam material roll 32, the first bottom film receiving roll 33, the second bottom film receiving roll 34, the material receiving sliding plate 35 and the pressing assembly 36 are all arranged on the second support seat 312. By arranging the first support seat 311 and the second support seat 312 which are slidably matched, when the foam material roll 32 needs to be replaced, the second support seat 312 can be slid relative to the first support seat 311 to the material replacement position to replace the foam material roll 32; after the replacement is completed, the second support seat 312 is slid relative to the first support seat 311 to the material taking position, so as to facilitate the foam laminating mechanism 4 to grab the corresponding foam from the material receiving sliding plate 35.

[0139] In this embodiment, a sliding rail is provided on the first support seat 311, and a sliding block is provided on the second support seat 312. The sliding block is slidably matched with the sliding rail to ensure the stability of the sliding process between the two. Of course, in other embodiments, the sliding rail can also be provided on the second support seat 312, and the sliding block can be provided on the first support seat 311, and the above-mentioned effect can also be achieved. Optionally, limiting protrusions are also provided on both sides of the first support seat 311. When the second support seat 312 abuts against the limiting protrusions, the second support seat 312 stops sliding, thereby limiting the sliding of the second support seat 312 to prevent the second support seat 312 from slipping off the first support seat 311.

[0140] Furthermore, a limiting cylinder 313 is provided on the first support seat 311, and a limiting hole is provided on the base of the second support seat 312. The output end of the limiting cylinder 313 can extend out and extend into the limiting hole at the bottom of the second support seat 312, thereby preventing the second support seat 312 from sliding when the foam bonding mechanism 4 takes material from the material-receiving sliding plate 35, thereby ensuring the accuracy of the material taking process.

[0141] Optionally, in this embodiment, the number of the foam feeding mechanisms 3 is two. The two foam feeding mechanisms 3 are arranged side by side on the base 700. When the foam material roll 32 of one of the foam feeding mechanisms 3 needs to be replaced, the foam bonding mechanism 4 can grab the foam from the other foam feeding mechanism 3, thereby saving the time of the foam bonding mechanism 4 stopping to wait for materials, and improving the bonding efficiency of the foam bonding device 100. This embodiment does not limit the number of the foam feeding mechanisms 3, and three, four or more can also be set, and the operator can adjust according to the actual production rhythm and layout space.

[0142] like Figure 16-Figure 17 As shown, the foam bonding mechanism 4 includes a bonding robot 41, a bonding connecting frame 42 and a foam adsorption component 43.

The foam laminating mechanism 4 can grab the foam from the foam feeding mechanism 3 according to the position information of the foam acquired by the laminating camera 44, and can also attach the grabbed foam to the adhesive layer of the screen to be attached according to the position information of the screen to be attached acquired by the laminating camera 44, thereby achieving accurate lamination between the screen to be attached and the foam.

[0145] It should be noted that the foam separated from the first base film and the second base film is also covered with a second protective film. After the foam bonding mechanism 4 attaches the foam to the screen body to be attached carried by the carrying mechanism 1, the second protective film covering the foam needs to be torn off. However, the area of ​​the second protective film is small and the thickness is thin, which is not convenient to clamp directly with the clamp. In order to solve this problem, the foam bonding device 100 also includes an easy-tear sticker peeling mechanism 5, which is used to carry and peel off the easy-tear sticker; the foam bonding mechanism 4 also includes a foam film tearing assembly 45, which is used to grab the easy-tear sticker peeled off from the easy-tear sticker peeling mechanism 5 and stick it on the second protective film covering the foam, and the foam film tearing assembly 45 can also tear off the second protective film on the foam through the easy-tear sticker. With this setting, the second protective film covering the foam can be easily torn off to avoid the screen body to be attached from being crushed, thereby ensuring the quality of the finished product.

[0146] Specifically, the foam film tearing assembly 45 includes a foam film tearing driving component 451, a foam film tearing fixed jaw 452 and a foam film tearing movable jaw 453.

The foam film tearing driving component 451 can drive the foam film tearing movable jaw 453 to move towards or away from the foam film tearing fixed jaw 452 to clamp or release the easy-to-tear sticker. Among them, the foam film tearing driving component 451 is specifically a foam film tearing driving cylinder.
