Description

Technical Field

[0001] This application relates to the technical field of LIPO encapsulated screens, and particularly to a rubber plug removal device for screen potting. Background Art

[0002] LIPO is a screen encapsulation technology that protects the connection of the display screen cable by using a polymer material for liquid encapsulation, and then cures the polymer material to tightly combine the polymer material, the display screen and the mobile phone middle frame, thereby reducing the border width of the mobile phone screen.

[0003] In the processing of LIPO screens, to ensure the reliability of the screens, potting is required. During the potting process, to prevent glue leakage and ensure accurate potting positions and good sealing, rubber plugs are usually used to block specific holes or gaps on the screens, and the rubber plugs are removed after potting is completed. In the prior art, the removal of rubber plugs often relies on manual operation. Workers need to use simple tools such as tweezers and remove the rubber plugs one by one based on experience and feel. However, this method of removing rubber plugs not only has low efficiency, but also because it is difficult for workers to accurately control the removal force and angle, workers are prone to damaging the screen during the process of removing the rubber plugs, affecting the yield rate of the products. Summary of the Invention

[0028] The following will Figures 1-6 further describe the present invention in detail with reference to the accompanying

[0029] In the description of the present invention, it should be understood that when it comes to orientation descriptions, such as the orientations or positional relationships indicated by up, down, front, back, left, right, etc., they are based on the orientations or positional relationships shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0030] See Figure 1 As shown, a rubber plug removal device for screen potting is shown, including a machine base 4. On the machine base 4, there is a conveying mechanism 1 for conveying the screen, a removal mechanism 2 for removing the rubber plug, and a collection mechanism 3 for collecting the rubber plugs.

[0031] In this embodiment, in combination with Figure 1 As shown, the conveying mechanism 1 includes a conveyor belt assembly 11 arranged along the length direction of the machine base 4. A plurality of loading positions for carrying the screen are arranged at intervals on the conveyor belt assembly 11. The carriers loaded with the screen are respectively carried on the plurality of loading positions and are conveyed forward along with the conveyor belt assembly 11. The removal mechanism 2 includes a first bracket 21 located on one side of the conveyor belt assembly, a removal claw 22 that is liftable and provided on the first bracket 21, and a first driving module 23 for driving the removal claw 22 to lift. The collection mechanism 3 includes a second bracket 31, a collection hopper 32 that is translatable along the width direction of the machine base and provided on the second bracket 31, and a second driving module 33 for driving the collection hopper 32 to move. The top of the collection hopper 32 has an opening for receiving the rubber plug. Among them, the first driving module 23 is a motor screw structure, and the second driving module 33 is a linear motor.

[0032] During the process of removing the rubber plug, the loading position and the collection hopper 32 can respectively pass directly below the removal claw 22 during their respective moving strokes. Specifically, the mold loaded with the screen is placed on the loading position and is conveyed forward along with the conveyor belt assembly 11. When the loading position reaches the removal mechanism 2, the removal claw 22 descends and removes the rubber plug on the mold. After the removal is completed, the removal claw 22 rises. Subsequently, the collection hopper 32 is translated to below the removal claw 22, and the removal claw 22 drops the rubber plug into the collection hopper 32. In this way, with the cooperation of the conveyor belt assembly 11, the removal claw 22, and the collection hopper 32, the rubber plug can be quickly removed and collected, which can not only improve the efficiency of rubber plug removal but also cause no damage to the screen.

[0033] In this embodiment, as Figure 1As shown in the figure, the conveyor belt assembly 11 includes two belt conveyors 111 arranged side by side and having the same conveying direction. The conveying directions of the two belt conveyors 111 are the same as the length direction of the machine base 4. The two side parts of the mold are respectively carried on the two belt conveyors 111. There are two demolding mechanisms 2, and the two demolding mechanisms 2 are arranged along the conveying direction of the conveyor belt assembly 11. When the molds at the two loading positions reach the two demolding mechanisms 2 respectively, the two demolding mechanisms 2 can simultaneously demold the rubber plugs on the two molds, and the demolding efficiency is high.

[0034] In this embodiment, there is a gap between the two belt conveyors 111. The conveying mechanism 1 further includes two lifting assemblies 12 arranged in the gap. The two lifting assemblies 12 correspond to the two demolding mechanisms 2 respectively. Each lifting assembly 12 is located directly below the corresponding demolding claw 22, and it includes a liftable lifting seat 121 and a third driving module 122 for driving the lifting seat 121 to lift. Among them, the third driving module 122 is a cylinder. When the loading position moves below the demolding claw 22, the demolding claw 22 descends and clamps the rubber plug. At this time, the lifting seat 121 can synchronously lift the mold on the loading position upward, so that the demolding claw 22 can contact the rubber plug faster, further improving the demolding efficiency.

[0035] In this embodiment, the conveyor belt assembly 11 further includes a third support 112. The third support 112 includes two relatively arranged frame bodies 1121. The two belt conveyors 111 are accommodated between the two frame bodies 1121, and each belt conveyor 111 is detachably connected to the adjacent frame body 1121. Among them, there are four third supports 112, and the four third supports 112 are arranged along the conveying direction of the conveyor belt assembly 11. The detachable setting enables the two belt conveyors 111 to be independently disassembled and repaired respectively when damaged, without having to repair the conveyor belt assembly 11 as a whole. This not only improves the repair efficiency but also saves the repair cost.

[0036] Further, as shown in combination Figure 2 In the figure, an installation hole 1122 is opened at the upper end of the frame body 1121. A retractable pressing block 1123 is arranged on the upper side hole wall of the installation hole 1122. The pressing block 1123 is connected to the hole wall of the installation hole 1122 through a spring 1124. A connecting column 1111 is arranged on the belt conveyor, and the connecting column 1111 is inserted into the installation hole 1122, and the pressing block 1123 is buckled on the side of the connecting column 1111.

[0037] In this embodiment, as shown in combination Figures 3-4As shown, the removal claw 22 includes a claw seat 221, two claw arms 222 which can be relatively opened or retracted and are arranged on both sides of the claw seat 221, and each claw arm 222 is respectively provided with a clamping groove 223 on the inner side thereof, and an anti-slip pattern 224 is arranged in the clamping groove 223. The two sides of the rubber plug can be respectively accommodated in the clamping grooves 223 of the two claw arms 222 and conflict with the anti-slip pattern 224, which effectively improves the clamping strength of the removal claw 22 on the rubber plug, and prevents the rubber plug from being separated from the removal claw 22 during the removal process and affecting its removal process.

[0038] Furthermore, the claw seat 221 includes a seat body 2211, two seat plates 2212 respectively connected to the bottom of the seat body 2211, the two seat plates 2212 are arranged opposite to each other and the upper ends of the two seats are respectively provided with long grooves 225 extending in the vertical direction, and a transmission column 226 is also arranged between the two seat plates 2212, and the two ends of the transmission column 226 are respectively slidably connected to the two long grooves 225, and there are two claw arms 222 and the two claw arms 222 are symmetrically arranged about the claw seat 221, and the arrangement direction of the two claw arms 222 is consistent with the arrangement direction of the two seat plates 2212. The claw 222 is vertically connected to each other, and each claw arm 222 includes a first arm body 2221 and a second arm body 2222 which are hinged to each other, and a clamp 2223 arranged at the lower end of the second arm body 2222. The upper end of the first arm body 2221 is hinged to the transmission column 226, and the second arm body 2222 is hinged to the lower end of the seat plate 2212. The removal claw 22 also includes a fourth driving module 227 for driving the transmission column 226 to slide. The fourth driving module 227 is a cylinder, and the piston rod of the cylinder is connected to the transmission column 226 and can be extended and retracted in the vertical direction.

[0039] During the telescopic stroke of the cylinder, it can drive the transmission column 226 to slide downward or upward. When the transmission column 226 slides downward, the two first arms 2221 push the two second arms 2222 downward respectively, and the two second arms 2222 rotate and drive the two clamps 2223 to open relatively. When the transmission column 226 slides upward, the two first arms 2221 pull the two second arms 2222 upward respectively, and the two second arms 2222 rotate and drive the two clamps 2223 to close relatively. Among them, the long groove 225 can guide and limit the transmission column 226, which can not only improve the opening and closing stability of the two clamps 2223, but also prevent the two clamps 2223 from being over-opened or over-closed, which will affect the removal of the rubber plug.

[0040] In this embodiment, combined again Figure 1As shown, the removal mechanism 2 further includes a mounting seat 24 that is liftable and disposed on the first bracket 21, and two alignment pins 25 respectively disposed on both sides of the bottom of the mounting seat 24. There are four removal claws 22, and the four removal claws 22 are arranged in a rectangular array on the mounting seat 24. The first driving module 23 is used to drive the mounting seat 24 to lift. The alignment pins 25 can cooperate with the positioning holes on the mold to achieve the positioning of the screen, effectively improving the removal accuracy of the removal claws 22.

[0041] Among them, the four removal claws 22 are respectively rotatably disposed on the mounting seat 24 around their own axis directions. The removal mechanism 2 further includes a fifth driving module 26 for driving the removal claws 22 to rotate, and the fifth driving module 26 is a motor. The removal claws 22 can rotate around their own axis directions when removing the rubber plug, so as to drive the rubber plug to rotate and make the rubber plug loose during the rotation process, effectively reducing the difficulty of removing the rubber plug and improving the efficiency of removing the rubber plug.

[0042] In this embodiment, in combination with Figures 5-6 As shown, the collection hopper 32 has an inclined first bottom wall 321. The collection mechanism 3 further includes a pushing component 34 disposed in the collection hopper 32. The pushing component 34 includes a pushing plate 341 that is movably disposed along the inclined direction of the first bottom wall 321, and a sixth driving module 342 for driving the pushing plate 341 to move. The pushing plate 341 can push the rubber plug along the inclined direction of the first bottom wall 321 to prevent the rubber plug from staying on the first bottom wall 321 and affecting the subsequent falling of the rubber plug.

[0043] Furthermore, annular first sliding grooves 35 are respectively formed on the opposite inner walls of the collection hopper 32. The first sliding grooves 35 include a first groove body 351 and a second groove body 352 that are arranged up and down and communicate with each other. The first groove body 351 and the second groove body 352 are parallel to each other and respectively extend along the inclined direction of the first bottom wall 321. Transmission rods 343 are respectively disposed at both ends of the pushing plate 341, and the two transmission rods 343 are respectively slidably connected to the two first sliding grooves 35. When the transmission rods 343 are located in the second groove body 352, the pushing plate 341 abuts against the first bottom wall 321; when the transmission rods 343 are located in the first groove body 351, the pushing plate 341 is separated from the first bottom wall 321. In this way, the pushing plate 341 can perform a forward stroke of pushing the material downward under the cooperation of the transmission rods 343 and the second groove body 352, and perform a reverse stroke of upward reset under the cooperation of the transmission rods 343 and the first groove body 351. In the reverse stroke, the pushing plate 341 is separated from the first bottom wall 321, effectively avoiding the interference of the pushing plate 341 on the subsequent falling of the rubber plug.

[0044] Among them, there are two sixth driving modules 342, which are respectively arranged at the upper parts of the inner walls on both sides of the collecting hopper 32. The two sixth driving modules 342 correspond to two transmission rods 343 one by one. Each sixth driving module 342 respectively includes a first driving seat 3421, a second chute 3422 opened on the first driving seat 3421 and extending along the length direction of the collecting hopper 32, a slider 3423 slidably arranged in the second chute 3422 along the extension direction of the second chute 3422, and a power member 3424 for driving the slider 3423 to slide. The power member 3424 is a cylinder. A connecting rod 3425 is hinged to the slider 3423. The connecting rod 3425 is L-shaped. The other end of the connecting rod 3425 extends into the collecting hopper 32 and is connected to the corresponding transmission rod 343.

[0045] In this embodiment, arc-shaped transition grooves 353 are respectively communicated between the two end portions of the first groove body 351 and the second groove body 352. The transmission rod 343 can reciprocate between the first groove body 351, the second groove body 352 and the two transition grooves 353. When the power member 3424 drives the slider 3423 to reciprocate, the pushing plate 341 moves synchronously with the slider 3423 under the drive of the connecting rod 3425. Since the connecting rod 3425 is hinged to the slider 3423, the slider 3423 moving along the horizontal direction can drive the pushing plate 341 to move along the inclined direction, effectively avoiding interference between the driving stroke of the slider 3423 and the moving stroke of the pushing plate 341.

[0046] Specifically, when the transmission rod 343 is in the second groove body 352, the pushing plate 341 abuts against the first bottom wall 321. At this time, the cylinder is in the extending stroke, and the piston rod of the cylinder can push the pushing plate 341 to move forward. The pushing plate 341 pushes the rubber plug on the first bottom wall 321 during the moving process; when the transmission rod 343 reaches the end of the second groove body 352, it can reach the first groove body 351 through the arc surface of one of the transition grooves 353; when the transmission rod 343 is in the first groove body 351, the pushing plate 341 is separated from the first bottom wall 321. At this time, the cylinder is in the retracting stroke, and the piston rod of the cylinder can pull the pushing plate 341 to move backward. The pushing plate 341 is separated from the first bottom wall 321 during the moving process and will not interfere with the subsequent rubber plugs; when the transmission rod 343 reaches the end of the first groove body 351, it can reach the second groove body 352 again through the arc surface of the other transition groove 353.

[0047] In this embodiment, combined again with Figures 5-6As shown in the figure, the collecting mechanism 3 further includes a buffer hopper 36 disposed below the collecting hopper 32 and a recycling box 37 disposed below the buffer hopper 36. Openings for receiving rubber stoppers are provided at the tops of both the buffer hopper 36 and the recycling box 37. A first discharge port 322 is provided at the bottom of the collecting hopper 32. The first discharge port 322 is always located above the opening of the buffer hopper 36 during the moving stroke of the collecting hopper 32. A second discharge port 361 is provided at the bottom of the buffer hopper 36, and the second discharge port 361 is located above the opening of the recycling box 37.

[0048] During the process that the collecting hopper 32 moves below the removing claw 22 and receives the rubber stoppers, the opening of the buffer hopper 36 is always located below the first discharge port 322, which can continuously receive the rubber stoppers in the collecting hopper 32 and prevent the rubber stoppers from falling outside and affecting the collection process. At the same time, due to the buffering effect of the buffer hopper 36, not only can the rubber stoppers in the collecting hopper 32 be prevented from directly hitting and being damaged inside the recycling box 37, but also the glue and impurities remaining on the rubber stoppers can remain in the buffer hopper 36 during the rolling process, effectively improving the cleanliness of the rubber stoppers collected in the recycling box 37 and facilitating the subsequent reuse of the rubber stoppers.

[0049] Among them, the buffer hopper 36 has an inclined second bottom wall 362, and the above-mentioned pushing component 34 is also provided on the second bottom wall 362. The above-mentioned first sliding grooves 35 are also provided on the opposite inner walls of the buffer hopper 36. The pushing component 34 and the first sliding grooves 35 in the buffer hopper 36 can cooperate with each other to push the rubber stoppers in the buffer hopper 36.

[0050] In this embodiment, the collecting mechanism 3 further includes a pull-out rack 38 that is translatable along the width direction of the machine base 4 and is disposed on the second bracket 31, and a material blocking component 39 for blocking the second discharge port 361 when the pull-out rack 38 moves. The bottom of the pull-out rack 38 is slidably connected to the machine base 4 through a guide rail 5, and the recycling box 37 is accommodated in the pull-out rack 38.

[0051] The material blocking component 39 includes a rotating shaft 391 that is rotatably inserted through the buffer hopper 36 around its own axis, a material blocking plate 392 disposed on the rotating shaft 391, two gears 393 respectively disposed at both ends of the rotating shaft 391, and two racks 394 respectively disposed on the upper parts of both sides of the pull-out rack 38. The rotation axis of the rotating shaft 391 is perpendicular to the moving direction of the pull-out rack 38. The two racks 394 are respectively engaged with the two gears 393, and the material blocking plate 392 can block the second discharge port 361 during the rotation of the rotating shaft 391.

[0052] Specifically, as Figure 6As shown in the figure, the baffle 392 is located on the right side of the second discharge port 361. After the recycling bin 37 is full, the staff needs to pull out the drawer rack 38 and unload the recycling bin 37.
