Description
Technical Field
[0001] This invention relates to the field of mobile phone assembly equipment, and in particular to an automatic mobile phone alignment and assembly equipment. Background Technology
[0002] During the mobile phone assembly process, mobile phone foam and copper foil need to be installed on the circuit board inside the phone. Before the mobile phone foam and copper foil are assembled onto the phone, their top surfaces are covered with a protective film. After assembly, the protective film needs to be removed.

[0015] The beneficial effects of this invention are as follows: The mobile phone body is transported to the left along with the carrier tray on the second assembly conveyor mechanism. The copper foil feeding mechanism and the foam feeding mechanism feed the copper foil and foam respectively. When the carrier tray reaches below the copper foil assembly robot, the copper foil assembly robot grabs the copper foil from the copper foil feeding mechanism and moves it to the second CCD detection component for image positioning. After positioning, the copper foil assembly robot assembles the copper foil onto the mobile phone. When the carrier tray reaches below the foam assembly robot, the foam assembly robot grabs the foam from the foam feeding mechanism and moves it to the second CCD detection component for image positioning. After positioning, the foam assembly robot assembles the foam onto the mobile phone. After assembling the copper foil and foam, the mobile phone body continues to be transported to the left to the second pressure holding mechanism, which holds the assembly position of the copper foil and foam under pressure to ensure a firm assembly. Then, the protective film on the copper foil and foam is removed by the second linkage film tearing mechanism. The protective film has a tear-off position protruding from the material. When tearing the film, the Z-axis drive component drives the linkage gripper component to descend. The second adsorption through-hole of the two grippers connects to the air extraction device and adsorbs the hand-tearable part of the protective film. The rotating drive assembly drives the mounting plate to rotate, causing the second gripper to rotate a certain angle towards the material side, peeling off the edge of the protective film. Then, the film-tearing drive cylinder drives the first connecting block to move closer to the second gripper side, while simultaneously driving the second connecting block to move. The roller moves downward in the strip hole, thereby driving the second gripper to slide in the arc-shaped through-hole. Under the action of the two sets of arc-shaped through-holes, the second gripper is equivalent to rotating around the center of the arc-shaped through-hole. The lower end of the second gripper moves closer to the first gripper side, thereby causing the first and second grippers to clamp the protective film tightly. At this time, the lower end of the second gripper is higher than the upper surface of the material due to rotation. The second X-axis drive assembly directly drives the linkage gripper assembly to move laterally, completely tearing off the protective film. Then, the Y-axis drive assembly and the rotating drive assembly move the protective film to the top of the recycling bin and release it, allowing it to fall into the recycling bin for recycling. Its advantage is that it not only improves the efficiency of film tearing but also does not damage the material. Attached Figure Description

After assembling the copper foil and foam, the phone body continues to be conveyed to the left to the second pressure holding mechanism 28, which holds pressure on the assembly position of the copper foil and foam to ensure a firm assembly. Then, the protective film on the copper foil and foam is removed by the linkage film tearing mechanism. The protective film has a tear-off position protruding from the material. When tearing the film, the Z-axis drive component 295 drives the linkage gripper component 297 to descend. The second suction through hole of the second gripper 2977 connects to the air extraction device and adsorbs the tear-off position of the protective film. The phone is then rotated to remove the protective film. The moving component 296 drives the mounting plate to rotate, causing the second gripper 2977 to rotate a certain angle toward the material side, peeling off the edge of the protective film. Then, the film-peeling drive cylinder 2972 drives the first connecting block 2973 to move closer to the second gripper 2977, simultaneously driving the second connecting block 2975 to move. The roller 2978 moves downward within the strip-shaped hole 29751, thereby driving the second gripper 2977 to slide within the arc-shaped through hole 29712. Under the action of the two sets of arc-shaped through holes 29712, the second gripper 2977 essentially rotates around the center of the arc-shaped through hole 29712. The lower end of the claw 2977 moves closer to the first claw 2976, thereby clamping the protective film between the first claw 2976 and the second claw 2977. At this time, the lower end of the second claw 2977 is higher than the upper surface of the material due to rotation. The second X-axis drive assembly 294 drives the linkage claw assembly 297 to move laterally, completely tearing off the protective film. Then, the Y-axis drive assembly 292 and the rotation drive assembly 296 move the protective film to the top of the recycling bin 298 and release it, allowing it to fall into the recycling bin 298 for recycling. Its advantage is that it can not only improve the efficiency of tearing the film, but also avoid damaging the material.
[0046] The first gripper 2976 has a gripping part 29761 at its lower end. The lower end of the gripping part 29761 is inclined toward the second gripper 2977. The first gripper 2976 has multiple sets of gripping protrusions 29762. The multiple sets of gripping protrusions 29762 are evenly distributed on the gripping part 29761 in the vertical direction and correspond to the side close to the second gripper 2977. The gripping protrusions 29762 have a first adsorption through hole.
[0047] The clamping boss 29762 can increase the pressure of the first gripper 2976 on the protective film and increase the friction, thereby making the clamping more secure. The first adsorption through hole is connected to the air extraction device. After the first gripper 2976 clamps the protective film, the first adsorption through hole adsorbs the protective film, thereby improving the clamping security of the protective film.
[0048] The second X-axis drive assembly 294, Z-axis drive assembly 295, rotary drive assembly 296, and linkage gripper assembly 297 are arranged in two sets each along the left and right directions on the mounting plate 293. This allows the second linkage film-tearing mechanism 29 to simultaneously remove the protective film from both the copper foil and the foam, improving production efficiency.
[0049] like Figures 2 to 6 As shown, the first pressure-holding mechanism 17 includes a pressure-holding roller assembly 171 and a pressure-holding partition assembly 172. The pressure-holding roller assembly 171 includes a first mounting bracket 1711, a first X-axis drive assembly 1712, a movable bracket 1713, a counterweight bracket 1714, a guide column 1715, a rolling roller 1716, a lifting cylinder 1717, and a top block. Two sets of first mounting brackets 1711 are arranged along the front-rear direction. The first X-axis drive assembly 1712 is fixed above the first mounting brackets 1711. Both the front and rear ends of the movable bracket 1713 are fixed. At the power output end of the first X-axis drive assembly 1712, a counterweight bracket 1714 is positioned above the movable bracket 1713, the upper end of a guide post 1715 is fixed below the counterweight bracket 1714, the lower end of the guide post 1715 passes through the movable bracket 1713, a rolling roller 1716 is rotatably mounted below the counterweight bracket 1714, a lifting cylinder 1717 is fixed on the counterweight bracket 1714 with its power output end facing downwards, and a top block is fixed at the power output end of the lifting cylinder 1717 and corresponds to the upper part of the movable bracket 1713.
[0050] The pressure-holding partition assembly 172 includes a second mounting bracket 1721, a fixing frame 1722, and a silicone plate 1723. The second mounting bracket 1721 is fixedly disposed below the rolling roller 1716, and the fixing frame 1722 is fixed above the second mounting bracket 1721. The fixing frame 1722 is provided with a mounting cavity, which vertically penetrates the fixing frame 1722. The silicone plate 1723 is fixed in the mounting cavity. The silicone plate 1723 is made of silicone with a hardness of 50 degrees.
[0051] The mobile phone is transported from right to left on the first assembly conveyor 12 along with the carrier tray. At the right end of the first assembly conveyor 12, the plasma fan 13 removes static electricity from the mobile phone body to facilitate the assembly of subsequent components. The graphite sheet feeding mechanism 15 feeds graphite sheets. When the carrier tray reaches below the graphite sheet assembly robot 16, the graphite sheet assembly robot 16 picks up the graphite sheet from the graphite sheet feeding mechanism 15 and moves it to the first CCD detection component 14 for imaging and positioning. After positioning, the graphite sheet assembly robot 16 assembles the graphite sheet onto the mobile phone. After the graphite sheet is installed on the mobile phone, it is transported sequentially to the first pressure holding mechanism 17 and the first linkage film peeling mechanism 18 along with the carrier tray. The graphite sheet is then pressure-held and the protective film on the graphite sheet is peeled off. During pressure holding, the mobile phone... The graphite sheet is located below the pressure-holding partition assembly 172. The carrier plate rises to contact the silicone plate 1723. Then, the lifting cylinder 1717 drives the top block to retract upwards, and the counterweight moves downwards under the action of gravity, so that the rolling roller 1716 contacts the upper surface of the silicone plate 1723. Next, the first X-axis drive assembly 1712 drives the movable bracket 1713 to move left and right, so that the rolling roller 1716 reciprocates on the silicone plate 1723 in the left and right direction. The lower end face contour of the silicone plate 1723 matches the contour of the graphite sheet, so that the silicone plate 1723 can hold pressure on the graphite sheet. Because the rolling roller 1716 reciprocates to apply pressure to various parts of the silicone plate 1723, the pressure holding on the graphite sheet is uniform and sufficient, avoiding insufficient pressure holding in some areas. After the pressure holding is completed, the lifting cylinder 1717 drives the top block to move downward. The top block contacts the movable bracket 1713 and lifts the counterweight bracket 1714, thereby causing the rolling roller 1716 to detach from the silicone plate 1723. A counterweight block of a specific weight can be installed on the counterweight bracket 1714 according to the pressure holding requirements. During the lifting and lowering process of the counterweight bracket 1714, the guide column 1715 slides vertically on the movable bracket 1713 to ensure smooth lifting and lowering of the counterweight bracket 1714.
[0052] The silicone plate 1723 is made of silicone with a hardness of 50 degrees. Its hardness is moderate and can effectively transfer the pressure applied by the rolling roller 1716 to the graphite sheet, resulting in better pressure retention.
[0053] The fixed frame 1722 includes a bottom frame 17221, a middle mounting plate 17222, a top frame 17223, bolts 17224, springs 17225, and pressure blocks 17226. The bottom frame 17221 is fixed above the second mounting bracket 1721. The middle mounting plate 17222 is positioned above the bottom frame 17221, and the top frame 17223 is positioned above the middle mounting plate 17222. The bolts 17224 pass through the pressure blocks 17226 and are threaded to the bottom frame 17221 at their ends. The springs 17225 are sleeved on the bolts 17224 and their inner sides contact the pressure blocks 17226. The inner sides of the pressure blocks 17226 contact the middle mounting plate 17222 and the top frame 17223. The upper inner side of the pressure blocks 17226 has a slope, which contacts the top frame 17223. The middle mounting plate 17222 has a mounting cavity in its middle.
[0054] Pushing the pressure block 17226 outwards facilitates placing the middle mounting plate 17222 and the top frame 17223 onto the bottom frame 17221. After releasing the pressure block 17226, under the action of the spring 17225, the inner side of the pressure block 17226 presses the middle mounting plate 17222 and the top frame 17223 towards the center. At the same time, the inclined surface on the pressure block 17226 presses the top frame 17223 downwards, thereby quickly fixing the middle mounting plate 17222.
[0055] The silicone plate 1723 includes a central pressure plate 17231 and an end insert plate 17232. The end insert plate 17232 is fixed on the left and right sides of the central pressure plate 17231. The outline of the mounting cavity matches the outline of the central pressure plate 17231 and the end insert plate 17232. The central pressure plate 17231 and the end insert plate 17232 are fixed in the mounting cavity. The outer end of the end insert plate 17232 corresponds to the space between the bottom frame 17221 and the top frame 17223.
[0056] The silicone plate 1723 is placed directly into the mounting cavity, and the end of the end insert plate 17232 is pressed together by the bottom frame 17221 and the top frame 17223, thereby quickly fixing the silicone plate 1723 onto the middle mounting plate 17222. The structure of the first linkage film tearing mechanism 18 is the same as that of the second linkage film tearing mechanism 29.
[0057] like Figures 13 to 19As shown, the spring-loaded film-tearing mechanism 33 includes a mounting base 331, a film-tearing motor 332, a connecting frame 333, a rotary motor 334, a first clamping component 335, a second clamping component 336, and a recycling dish 337. The mounting base 331 includes a mounting base plate 3311, a first mounting frame 3312, a second mounting frame 3313, and a third mounting frame 3314. The first mounting frame 3312, the second mounting frame 3313, and the third mounting frame 3314 are all fixed above the mounting base plate 3311. The film-tearing motor 332 is fixed to the first mounting frame. The upper end of the connecting frame 3312 is facing downward to the left, the lower end of the connecting frame 333 is fixed to the power output end of the film tearing motor 332, the rotary motor 334 is fixed to the upper end of the connecting frame 333 with its power output end facing to the left, the first clamping component 335 is fixed to the power output end of the rotary motor 334, the second clamping component 336 is fixed to the upper end of the second mounting frame 3313 and corresponds to the left side of the first clamping component 335, and the recycling dish 337 is fixed to the upper end of the third mounting frame 3314 and corresponds to the lower part of the first clamping component 335.
[0058] The mobile phone body is transported to the left on the third assembly conveyor mechanism 32 along with the carrier tray. When it arrives at the assembly station, the spring piece assembly robot 35 picks up the spring piece from the spring piece feeding mechanism 34 and moves it to the spring piece film tearing mechanism 33 to remove the protective film on the bottom of the spring piece. Then, the spring piece is assembled onto the mobile phone body. After the spring piece is assembled, the mobile phone body continues to be transported to the left to the third pressure holding mechanism 36, which holds the spring piece assembly position to ensure that it is firmly assembled. With two sets of spring piece film tearing mechanisms 33, spring piece feeding mechanisms 34 and spring piece assembly robot 35, multiple sets of spring pieces can be assembled at the same time, improving assembly efficiency.
[0059] The spring piece assembly robot 35 picks up the spring piece and moves it to the second clamping component 336. At this time, the second clamping component 336 controls its two sets of grippers to clamp the front and rear sides of the spring piece. The protective film is located on the lower end face of the spring piece, and the protruding position on the protective film corresponds to the space between the upper and lower sets of grippers of the first clamping component 335. The first clamping component 335 clamps the protruding position of the protective film. The film-tearing motor 332 drives the connecting frame 333 to move the first stroke, tearing the protective film to the lower left. Since the second clamping component 336 clamps the spring piece at this time, it can prevent the spring piece from shifting. After the protective film has partially detached from the spring piece... The second clamping component 336 is released, and the robotic arm lifts the spring piece upwards a certain distance. Then, the film-tearing motor 332 drives the connecting frame 333 to move the second stroke, continuing to tear off the protective film to the lower left. The first clamping component 335 is driven to rotate by the rotary motor 334, thereby completely tearing off the protective film. The second clamping component 336 releases the protective film, causing it to fall into the recycling dish 337. The advantage of this design is that it can reduce the force on the spring piece when tearing off the protective film and clamp and fix the spring piece, avoiding displacement of the spring piece during the film-tearing process, and ensuring the accuracy and stability of the spring piece during subsequent installation.
[0060] The spring-loaded film-tearing mechanism 33 further includes a limiting component 338, which includes a fixed block 3381, a movable block 3382, an elastic component 3383, and a limiting post 3384. The fixed block 3381 is fixed on the first mounting frame 3312, and the length direction of the fixed block 3381 is perpendicular to the movement direction of the connecting frame 333. The movable block 3382 is fixed on the connecting frame 333, and the length direction of the movable block 3382 is parallel to the length direction of the fixed block 3381. The elastic component 3383 and the limiting post 3384 are both fixed on the movable block 3382 and protrude toward the fixed block 3381. The protruding length of the elastic component 3383 is greater than the protruding length of the limiting post 3384.
[0061] When the film-tearing motor 332 drives the connecting frame 333 to move in the first stroke, the movable block 3382 moves with the connecting frame 333. The elastic end of the elastic component 3383 contacts the fixed block 3381 and is compressed, which plays a buffering role. When the film-tearing motor 332 drives the connecting frame 333 to move in the second stroke, the elastic component 3383 continues to be compressed until the limit post 3384 contacts the fixed block 3381, and then the movable block 3382 stops, completing the second stroke.
[0062] The first mounting bracket 3312 is adjustable in both the left-right and front-back directions on the mounting base plate 3311; the second mounting bracket 3313 is adjustable in the front-back direction on the mounting base plate 3311, and the second gripper 2977 is adjustable in the vertical direction on the second mounting bracket 3313; the third mounting bracket 3314 is adjustable in the front-back direction on the mounting base plate 3311, and the recovery dish 337 is adjustable in the vertical direction on the third mounting bracket 3314. The positions of the first clamping component 335, the second clamping component 336, and the recovery dish 337 are all flexibly adjustable to accommodate springs of different sizes.
[0063] The spring feeding mechanism 34 includes a mounting platform 341, a Y-axis conveying assembly 342, a vertical baffle 343, a first lifting drive assembly 344, a second lifting drive assembly 345, a first lifting carrier plate 346, a second lifting carrier plate 347, and a handling robot 348. The Y-axis conveying assembly 342 includes a rotary drive component 3421, a left conveyor belt component 3422, and a right conveyor belt component 3423 fixed on the mounting platform 341. The left conveyor belt component 3422 and the right conveyor belt component 3423 are both connected to the power output end of the rotary drive component 3421. The vertical baffle 343 is fixed to the rear side of the mounting platform 341 and corresponds to... Between the left conveyor belt component 3422 and the right conveyor belt component 3423, the first lifting drive assembly 344 is fixed on the front side of the mounting platform 341 and corresponds to the left conveyor belt component 3422 and the right conveyor belt component 3423. The second lifting drive assembly 345 is fixed on the rear side of the mounting platform 341 and corresponds to the first lifting drive assembly 344 and the vertical baffle 343. The first lifting platform 346 and the second lifting platform 347 are respectively fixed on the upper ends of the first lifting drive assembly 344 and the second lifting drive assembly 345. The handling robot 348 is mounted above the first lifting platform 346 and the second lifting platform 347.
[0064] The spring clips are neatly arranged in the trays. Multiple trays are neatly stacked and placed on the first lifting platform 346. The first lifting drive assembly 344 descends, placing the trays on the left conveyor belt assembly 3422 and the right conveyor belt assembly 3423 and transporting them backward until the trays contact the vertical baffle 343. Then, the second lifting drive assembly 345 drives the second lifting platform 347 to rise, lifting the trays upward and separating them from the left conveyor belt assembly 3422 and the right conveyor belt assembly 3423. In the subsequent process, the robot arm takes materials from the top tray. When the spring clips in the top tray are empty, the handling robot arm 34848 transports the empty trays to the first lifting platform 346. The first lifting platform 346 descends one level for each empty tray placed on it, and the second lifting platform 347 rises one level for each tray removed. After all the trays are empty and placed on the first lifting platform 346, they are removed in batches and replaced with the next batch of trays. The advantage of this design is that it can improve the efficiency of feeding and unloading materials, and it occupies a small area and has a low production cost.
[0065] The first lifting platform 346 has a first guide block 3461 on both the front and rear sides above it, and the two sets of first guide blocks 3461 have a guide slope on the opposite side. The second lifting platform 347 has a second guide block 3471 on both the front and rear sides above it, and the two sets of second guide blocks 3471 have a guide slope on the opposite side. The first guide block 3461 can quickly and accurately place the pallet at a specific position on the first lifting platform 347, and can prevent the pallet from shifting during the lifting process. The second guide block 3471 has the same function as the first guide block 3461.
[0066] The handling robot 348 includes a Y-axis motor 3481, a Z-axis cylinder 3482, and a mechanical gripper 3483. The Y-axis motor 3481 is fixed on the mounting platform 341, the Z-axis cylinder 3482 is fixed at the power output end of the Y-axis motor 3481, and the mechanical gripper 3483 is fixed at the power output end of the Z-axis cylinder 3482. The mechanical gripper 3483 is positioned above the first lifting platform 346 and the second lifting platform 347. Through the cooperation of the Y-axis motor 3481 and the Z-axis cylinder 3482, the mechanical gripper 3483 is driven to move back and forth and lift, thereby realizing the gripping and handling of the pallet.
[0067] The spring feeding mechanism 34 also includes a positioning component 349, which includes a first limiting plate 3491, a second limiting plate 3492, a Y-axis cylinder 3493, and an L-shaped clamping plate 3494. The first limiting plate 3491 is vertically fixed on the mounting platform 341 and corresponds to the front two sides of the Y-axis conveying component 342. The second limiting plate 3492 is vertically fixed on the mounting platform 341 and corresponds to the rear two sides of the Y-axis conveying component 342. The Y-axis cylinder 3493 is fixed at the upper end of the second limiting plate 3492. The power output ends of the two sets of Y-axis cylinders 3493 are arranged facing each other. The vertical plate of the L-shaped clamping plate 3494 is fixed to the power output end of the Y-axis cylinder 3493, and the horizontal plate of the L-shaped clamping plate 3494 faces upward.
[0068] The first limiting plate 3491 and the second limiting plate 3492 can limit the left and right sides of the stacked pallets to prevent the pallets from falling due to vibration. During the removal of the spring clip, the Y-axis cylinder 3493 drives the L-shaped clamping plate 3494 to clamp the top pallet. At the same time, the horizontal plate of the L-shaped clamping plate 3494 corresponds to the edge of the pallet to prevent the pallet from tilting on one side and ensure that the pallet is in a precise position when the spring clip is grabbed.
