Description

Technical Field

[0001] This invention relates to the field of glass cover assembly technology, and in particular to an automatic film-removing assembly device and method for glass covers. Background Technology

[0002] Currently, various electronic products incorporate displays. During display assembly, a glass cover plate needs to be attached to the product body. Before assembling the glass cover plate, the protective film on it must be removed. However, for automated production lines, this film removal is difficult to achieve, and even if it could be done, its efficiency is lower than manual removal. Therefore, in highly automated electronic product display assembly lines, relying solely on automated equipment for the film removal process not only fails to guarantee product quality but also hinders overall production efficiency. Thus, it is necessary to develop an automated glass cover plate film removal and assembly device that scientifically configures the manual film removal station. This device effectively synergizes the flexibility and efficiency of manual film removal with the precision and scale of automated production lines. It solves the technical challenges of automated film removal while fully leveraging the advantages of manual operation, achieving efficient coordination between various production stages and significantly improving the overall production line's efficiency and product qualification rate.

[0012] An automatic film-removing assembly method for glass cover plates, using an automatic film-removing assembly device for glass cover plates, includes the following steps: S1, an empty positioning fixture is conveyed to a fixture loading mechanism via a return conveyor belt; S2, the fixture loading mechanism picks up the product body and glass cover plate from the previous process and places them sequentially on the positioning fixture; S3, the product body and glass cover plate are conveyed to the first set of distribution conveyor platforms along with the positioning fixture. The distribution conveyor platforms allocate the conveying path of the positioning fixture according to the operation status of the film-removing station. When the film-removing station is idle, the positioning fixture is conveyed to that film-removing station. When the film-removing station is in operation, the positioning fixture is conveyed to the second X-axis conveyor assembly and continues to be conveyed to the next set of distribution conveyor platforms. Subsequent distribution conveyor platforms continue to allocate positioning fixtures according to the operation status of the film-removing stations in this set; S4, at the film-removing station, the protective film on the glass cover plate is manually removed. The glass cover plate after film removal is returned to the positioning fixture and conveyed to the next set of distribution conveyor platforms. S5. The first distribution mechanism distributes the fixtures on the first X-axis conveying assembly and the second X-axis conveying assembly of the last set of flipping and tearing film mechanisms, and evenly conveys them to the multiple conveying production lines of the assembly mechanism; S6. The assembly mechanism assembles the glass cover plate onto the product body, and conveys the positioning fixtures on the multiple conveying production lines of the assembly mechanism to the fixture unloading mechanism through the second distribution mechanism; S7. The fixture unloading mechanism takes out the product from the positioning fixture and places it in the downstream equipment, and conveys the empty positioning fixture to the fixture loading mechanism through the return conveyor belt on each mechanism.

[0013] The beneficial effects of this invention are as follows: The main body of the product and the glass cover are transported from the previous process to the distribution conveyor platform along with the fixture. The Y-axis conveyor component drives the distribution conveyor platform to connect with the first X-axis conveyor component. The fixture is moved above the fixture lifting component through the conveyor belt on the distribution conveyor platform and the first X-axis conveyor component. Then, the fixture lifting component lifts the fixture upward, causing it to detach from the conveyor belt. Next, the rotary drive component drives the picking plate to flip to a horizontal state. The first Z-axis drive component drives the lifting bracket to descend, so that the picking suction cup contacts the glass cover on the fixture. The rotary clamping cylinder drives the pressing block to rotate and press down on the pressing plate, thereby pressing the picking plate down a certain distance to ensure that the picking suction cup can successfully pick up the glass cover. Then, the picking plate returns to a vertical state, and the operator can remove the protective film on the glass cover. After removing the film, the picking plate is flattened again, and the glass cover is placed back on the fixture. This design allows for the installation of multiple automatic film-tearing mechanisms side-by-side. When one mechanism is in the film-tearing operation, the Y-axis conveyor component drives a distribution conveyor platform to connect with the second X-axis conveyor component, transporting the film to the next distribution conveyor platform. This next platform then transports the fixture to the film-tearing station or continues to the next film-tearing mechanism based on the current film-tearing station's operating status. Furthermore, glass covers that have already had their film peeled at the tearing station are transported to the next process via the next distribution conveyor platform as the fixture continues to move to the right, without needing to return to the original distribution conveyor platform, thus improving conveying efficiency. The advantage of this design is that it combines automated conveying with manual film peeling, improving both the film-tearing efficiency of the glass covers and the conveying efficiency of the fixture, thereby increasing the overall production line efficiency.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings:

It also includes a positioning fixture 7 for carrying workpieces. The fixture feeding mechanism 1 is used to place workpieces on the positioning fixture 7. Multiple sets of flipping film-tearing mechanisms 2 are arranged side by side along the conveying direction. Both the flipping film-tearing mechanism 2 and the assembly mechanism 4 are equipped with multiple sets of conveying lines. The first distribution mechanism 3 is used to distribute and convey the positioning fixtures 7 on the multiple sets of conveying lines of the flipping film-tearing mechanism 2 to the multiple sets of conveying lines of the assembly mechanism 4. The second distribution mechanism 5 is used to distribute and convey the positioning fixtures 7 on the multiple sets of conveying lines of the assembly mechanism 4 to the fixture unloading mechanism 6.

The distribution conveyor platform 24 is fixed at the power output end of the Y-axis conveyor assembly 23. The first X-axis conveyor assembly 25 and the second X-axis conveyor assembly 26 are... 6 are fixed on the upper right side of the mounting platform 22 and respectively correspond to the front and rear sides of the Y-axis conveyor assembly 23. The front and rear sides of the distribution conveyor platform 24, the first X-axis conveyor assembly 25, and the second X-axis conveyor assembly 26 are all provided with conveyor belts for conveying the fixture. The fixture lifting assembly 27 is fixed on the mounting platform 22 with its power output end facing upward. The lifting assembly corresponds to the two sets of conveyor belts of the first X-axis conveyor assembly 25. The cover plate flipping assembly 28 includes an adjusting base 281, an adjusting bracket 282, and a first Z-axis drive assembly 283. The components include a lifting bracket 284, a rotary drive assembly 285, a material handling plate 286, a rotary clamping cylinder 287, and a clamping block 288. An adjusting base 281 is fixed on the mounting platform 22 and corresponds between the first X-axis conveying assembly 25 and the second X-axis conveying assembly 26. An adjusting bracket 282 is fixed above the adjusting base 281 and its position is adjustable in the front-to-back direction. A first Z-axis drive assembly 283 is fixed on the adjusting bracket 282.

[0033] The main body of the product and the glass cover are transported from the previous process to the distribution conveyor platform 24 along with the fixture. The Y-axis conveyor assembly 23 drives the distribution conveyor platform 24 to connect with the first X-axis conveyor assembly 25. The fixture is moved above the fixture lifting assembly 27 by the conveyor belt on the distribution conveyor platform 24 and the first X-axis conveyor assembly 25. Then, the fixture lifting assembly 27 lifts the fixture upward, causing it to detach from the conveyor belt. Next, the rotary drive assembly 285 drives the material pick-up plate 286 to flip to a horizontal state. The first Z-axis drive assembly... 283 drives the lifting bracket 284 to descend, causing the material suction cup 2861 to contact the glass cover plate on the fixture. The rotating clamping cylinder 287 drives the clamping block 288 to rotate and press down on the clamping plate 2862, thereby causing the material picking plate 286 to press down a certain distance to ensure that the material suction cup 2861 can successfully pick up the glass cover plate. Then, the material picking plate 286 returns to the vertical position, and the operator can then remove the protective film on the glass cover plate. After removing the film, the material picking plate 286 is flattened again, and the glass cover plate is placed back on the fixture. The automatic flipping and film-tearing mechanism 2 of this design can be arranged in multiple sets side by side. When the current set of mechanisms is in the film-tearing operation, the Y-axis conveyor assembly 23 drives the distribution conveyor platform 24 to connect with the second X-axis conveyor assembly 26 and convey it to the next set of distribution conveyor platforms 24. The next set of distribution conveyor platforms 24 then conveys the fixture to the film-tearing station or continues to convey it to the next set of film-tearing mechanisms according to the working status of the film-tearing station. Moreover, the glass cover plates that have completed film-tearing at the film-tearing station are conveyed to the next process through the next set of distribution conveyor platforms 24 as the fixture continues to be conveyed to the right, without having to return to the original set of distribution conveyor platforms 24, thus improving conveying efficiency. The advantage of this design is that it can combine automated conveying and manual film-tearing, improving the film-tearing efficiency of glass cover plates and the conveying efficiency of fixtures, thereby improving the overall production efficiency of the production line.

The fixed suction cup 277 is provided in multiple sets and corresponds one-to-one with the multiple sets of suction cup through holes 2751.

[0035] When the fixture moves above the first lifting plate 275, the second Z-axis drive assembly 272 drives the pressure sensor 274 and the first lifting plate 275 to rise, thereby lifting the fixture and removing it from the conveyor belt. Then, the third Z-axis drive assembly 273 drives the second lifting plate 276 to rise, thereby driving the fixed suction cup 277 to pass upward through the suction cup through hole 2751 and adhere to the bottom of the fixture, so that the material removal plate 286 can remove the glass cover from the fixture. During the process of lifting the fixture and removing the glass cover, the pressure sensor 274 will detect the pressure to avoid damaging the workpiece.

[0037] For a fixture equipped with clamps, a lever assembly 278 is provided on the fixture lifting assembly 27 to push the clamps outward, thereby opening the clamps and releasing the workpiece. The third Z-axis drive assembly 273 drives the second lifting plate 276 to rise, causing the vertical lever 2783 to pass through the lever clearance 2752 and be positioned inside the clamp. The lever cylinder 2781 causes the drive block 2782 to move outward, thereby driving the vertical lever 2783 to push the clamps outward, ultimately releasing the workpiece.

The lifting device 43 is fixed on the worktable 41 and corresponds to the area between the two sets of conveyor belts. The alignment assembly device 44 includes a support frame 441, a Z-axis slide 442, and a first Z-axis drive. The assembly includes a moving component 443, a lifting frame 444, an XY-axis drive component 445, a rotary drive component 446, a gantry frame 447, and an assembly component 448. A support frame 441 is fixed below the worktable 41. The Z-axis slide 442 and the first Z-axis drive component 443 are both fixed to the support frame 441. The lifting frame 444 is fixed to the power output end of the first Z-axis drive component 443 and slidably connected to the Z-axis slide 442. The XY-axis drive component 445 is fixed to the lifting frame 444, and the rotary drive component 446 is fixed to the XY-axis drive component 447. The power output end of 45, the bottom of the gantry frame 447 is fixed to the power output end of the rotary drive component 446 and passes through the worktable 41 on both sides, the assembly component 448 is fixed to the top of the gantry frame 447, the assembly component 448 corresponds to the top of the lifting device 43, and the bottom of the assembly component 448 is provided with a suction cup for adsorbing the workpiece. The alignment detection device 45 includes a mounting frame 451, a second Z-axis drive component 452, a lifting component 453 and a camera component 454. The mounting frame 451 is fixed on the worktable 41 and mounted on the assembly component. Above component 448, the second Z-axis drive component 452 is fixed to the top of the mounting frame 451 with its power output end facing downwards. The lifting component 453 is fixed to the power output end of the second Z-axis drive component 452 and is slidably connected to the mounting frame 451. The camera component 454 is fixed on the lifting component 453. Four sets of camera components 454 are provided and correspond to the four corners of the assembly component 448 respectively. The X-axis conveying device 42, the lifting device 43, the alignment assembly device 44, and the alignment detection device 45 are each arranged in two sets along the front and rear sides of the worktable 41.

[0041] The product body and glass cover are placed together in a fixture, and the fixture is transported to the top of the lifting device 43 via the X-axis conveyor 42. The lifting device 43 lifts the fixture upward, detaching it from the conveyor belt. Then, the first Z-axis drive component 443 drives the assembly component 448 to descend. The suction cup at the lower end of the assembly component 448 attracts the glass cover on the fixture. The first Z-axis drive component 443 drives the glass cover to rise a certain distance. Then, the second Z-axis drive component 452 drives the lifting component 453 to slide downward on the mounting bracket 451, bringing the camera component 454 close to the glass cover and taking pictures to locate the position of the glass cover and the product body. Four sets of camera components 454 are set up to capture and detect the four corners of the glass cover, improving the accuracy of position detection. Based on the detected position information, the XY axis drive component 445 drives the glass cover to move horizontally, while the rotation drive component 446 drives the glass cover to rotate horizontally until the glass cover moves to the required assembly position. Then, driven by the first Z axis drive component 443, the glass cover is pressed down onto the product body and assembled with it. After assembly, the lifting device 43 drives the fixture to descend, and the fixture is placed back on the conveyor belt. The assembled product continues to be transported to the next process along with the fixture. The advantages of this design are: by using the alignment detection device 45 to capture and position the glass cover and the product body through visual inspection, the accuracy of position detection and the precision of assembly can be improved. Furthermore, by setting suction cups on the assembly component 448 to grip and assemble the glass cover, the structural complexity of the assembly component 448 can be reduced to a minimum, the risk of interference can be reduced, and thus the assembly efficiency can be improved.

[0042] The X-axis conveying device 42 includes a first-stage conveying component 421, a second-stage conveying component 422, and a connecting conveying component 423. Both the first-stage and second-stage conveying components 421 and 422 are fixed above the worktable 41. Conveyor belts are provided on both the front and rear sides of the first-stage and second-stage conveying components 421 and 422. The connecting conveying component 423 is fixed on the worktable 41 and corresponds between the first-stage and second-stage conveying components 421 and 422. The connecting conveying component 423 includes a Y-axis slide 4231, a Y-axis cylinder 4232, a movable frame 4233, and a connecting conveyor belt 4234. The Y-axis slide 4231 is fixed on the worktable 41 in the front-to-back direction, and the Y-axis cylinder 4232 is also fixed on the worktable 41. The movable frame 4233 is fixed to the power output end of the Y-axis cylinder 4232 and its lower end is slidably connected to the Y-axis slide table 4231. The connecting conveyor belt 4234 is installed on the upper end of the movable frame 4233. The movable frame 4233 and the connecting conveyor belt 4234 are both located inside the gantry frame 447. Two sets of the Y-axis cylinder 4232, the movable frame 4233 and the connecting conveyor belt 4234 are each set on the Y-axis slide table 4231. The two sets of connecting conveyor belts 4234 are arranged opposite to each other. The lifting device 43 is located between the two sets of connecting conveyor belts 4234. The left ends of the two sets of connecting conveyor belts 4234 are respectively connected to the two sets of conveyor belts of the first section of the conveyor belt, and the right ends of the two sets of connecting conveyor belts 4234 are respectively connected to the two sets of conveyor belts of the second section of the conveyor belt.

[0043] In the conveying state, two sets of Y-axis cylinders 4232 drive two sets of connecting conveyor belts 4234 to move closer together, thereby connecting the two sets of connecting conveyor belts 4234 with the conveyor belts on the first-stage conveyor component 421 and the second-stage conveyor component 422. This allows the fixture on the first-stage conveyor component 421 to be conveyed onto the connecting conveyor component 423. Then, under the conveying of the connecting conveyor belts 4234, the fixture is positioned above the lifting device 43. The lifting device 43 lifts the fixture and detaches it from the connecting conveyor belts 4234. Subsequently, the two sets of Y-axis cylinders 4232 drive two sets of connecting conveyor belts 4234 to move closer together, thereby connecting the two sets of connecting conveyor belts 4234 with the conveyor belts on the first-stage conveyor component 421 and the second-stage conveyor component 422. The cylinder 4232 drives the two sets of connecting conveyor belts 4234 to move away, providing a more spacious supplementary lighting environment for the light source component on the camera component 454, and also providing more operating space for the alignment and assembly device 44. After assembly, the two sets of connecting conveyor belts 4234 move back together, the lifting device 43 puts the fixture back onto the connecting conveyor belts 4234, the connecting conveyor belts 4234 transport the fixture to the second-stage conveyor component 422, and the second-stage conveyor component 422 continues to transport the fixture to the next process.

[0046] like Figures 11 to 14 As shown, the positioning fixture 7 includes a fixture base plate 71, a mounting plate 72, a first clamp assembly 73, and a second clamp assembly 74. The fixture base plate 71 has a placement cavity 711 in the middle. Each of the four corners of the fixture base plate 71 corresponding to the placement cavity 711 has a limiting boss 712. Each limiting boss 712 has a supporting plane 7121, a lower limiting arc surface 7122, and an upper limiting arc surface 7123. The upper end of the lower limiting arc surface 7122 is connected to the inner side of the supporting plane 7121, and the lower end of the upper limiting arc surface 7123 is connected to the outer side of the supporting plane 7121. The fixture base plate 71 has a supporting plane 7121, a mounting plate 72, a first clamp assembly 73, and a second clamp assembly 74. Mounting bosses 713 are provided on all four sides of the fixture. The mounting plate 72 is fixed to the lower end of the fixture base plate 71 and has a mounting cavity between it and the mounting bosses 713. The fixture base plate 71 has a first clearance hole 714 corresponding to the inner side of the mounting cavity. The first clamp assembly 73 includes a first slide 731, a first slider 732, a first elastic telescopic member 733, and a first clamping block 734. The first slide 731 is fixed above the mounting plate 72. The upper end of the first slider 732 is fixed to the first clamping block 734 and the lower end is slidably connected to the first slide 731. The two ends of the first elastic telescopic member 733 are respectively fixed to the fixture base plate. The outer side of the plate 71 and the first clamping block 734, the outer end of the first clamping block 734 corresponds to the mounting cavity, the inner end of the first clamping block 734 corresponds to the first clearance hole 714 and the lower side of the placement cavity 711, the first clamping assembly 73 is provided in multiple sets and respectively corresponds to a pair of right angle sides of the placement cavity 711, the second clamping assembly 74 includes a second slide 741, a second slider 742, a second elastic telescopic member 743 and a second clamping block 744, the second slide 741 is fixed above the mounting sealing plate 72, the upper end of the second slider 742 is fixed on the second clamping block 744 and the lower end is connected to the second slide 741. The sliding connection is provided. The two ends of the second elastic telescopic member 743 are respectively fixed to the outside of the fixture base plate 71 and the second clamping block 744. The outer end of the second clamping block 744 corresponds to the installation cavity, and the inner end of the second clamping block 744 corresponds to the second clearance hole 715 and the upper side of the placement cavity 711. The mounting boss 713 is provided with a first limiting block 71321 corresponding to the installation cavity. The outer side of the second clamping block 744 is provided with a second limiting block 7441. The inner end face of the second limiting block 7441 contacts the outer end face of the first limiting block 71321. The inner side of the second clamping block 744 is provided with a V-groove 7442.

[0047] The positioning fixture 7 of this design is conveyed sequentially to each processing station via a conveyor belt. At each processing station, a lever is provided that can pass through the first clearance hole 714. By driving the lever to move outward, the first slider 732 and the second slider 742 are driven to move outward along the first slide table 731 and the second slide table 741, so that the first clamping block 734 and the second clamping block 744 respectively compress the first elastic telescopic member 733 and the second elastic telescopic member 743, thereby putting the first clamping assembly 73 and the second clamping assembly 74 in the open state. In the open state of the positioning fixture 7, the main body of the product is placed on the lower side of the placement cavity 711, and the lower end of the main body of the product is in contact with the bottom of the placement cavity 711. The four corners of the main body of the product are initially constrained by the lower limit arc surface 7122. The glass cover is positioned on the upper side of the placement cavity 711. The lower ends of the four corners of the glass cover rest on the support plane 7121. The four corners of the glass cover are initially positioned under the constraint of the upper limit arc surface 7123. When the lever is reset, the first clamping block 734 on the two right-angled sides of the placement cavity 711 pushes the main body of the product and cooperates with the inner wall of the placement cavity 711, thereby fixing the main body of the product in the horizontal direction. The second clamping block 744 around the placement cavity 711 also moves towards the glass cover until the inner end face of the second limiting block 7441 contacts the outer end face of the first limiting block 71321 and then stops. At this time, the four edges of the glass cover are all in the V-groove 7442, thereby enabling precise positioning and fixing of the glass cover. The advantage of this design is that it can flexibly open or clamp the first clamp assembly 73 and the second clamp assembly 74 at each processing station, thereby facilitating operations such as tearing the film and aligning the glass cover to meet the needs of automated production and improve production efficiency and accuracy.

[0048] The mounting boss 713 includes a top mounting plate 7131 and an adjusting block 7132. The lower end of the top mounting plate 7131 is connected to the base plate 71 of the fixture. A sliding groove 71311 is provided on the top mounting plate 7131. The adjusting block 7132 is fixed in the sliding groove 71311 by screws and is slidably connected with the sliding groove 71311. A first limiting block 71321 is provided below the adjusting block 7132.

[0049] By manually driving the adjusting block 7132 to move within the sliding groove 71311 and fixing the adjusting block 7132 with screws, the distance between the first limiting block 71321 and the edge of the glass cover can be adjusted, thereby limiting the maximum distance that the second clamping block 744 moves into the placement cavity 711. This allows for flexible adjustment of the clamping pressure on the glass cover according to the clamping pressure requirements, preventing excessive pressure from damaging the glass cover. Alternatively, according to production needs, the pressure of the second clamping block 744 on the glass cover can be adjusted so that the lower end of the V-groove 7442 supports the edge of the glass cover.

[0050] The fixture base plate 71 is provided with multiple sets of second clearance holes 715, with one set of second clearance holes 715 on each side of the limiting boss 712.

[0051] The second clearance hole 715 allows the positioning camera and supplementary light source to work together through the second clearance hole at the alignment station to capture and position the four corners of the product body and the glass cover.

[0052] The fixture base plate 71 is also provided with suction cup clearance holes 716, and four sets of suction cup clearance holes 716 are provided, corresponding to the four corners inside the placement cavity 711.

[0053] Suction cups can be installed at each processing station. The suction cups pass upward through the suction cup clearance holes 716 and adsorb onto the lower end face of the product body, thereby achieving vertical fixation. Four sets of suction cup clearance holes 716 are set, not only to ensure that the suction cups are evenly distributed, but also so that for products with cameras such as mobile phones and tablets, the protruding camera can be aligned with the suction cup clearance holes 716, allowing the product body to be placed flat. Moreover, the four sets of suction cup clearance holes 716 can adapt to different placement directions of the product body.

[0054] The fixture base plate 71 is also provided with anti-mistake through holes 717. Two sets of anti-mistake through holes 717 are provided in the placement cavity 711, and the diameters of the two sets of anti-mistake through holes 717 are not equal.

[0055] Positioning rods can be installed at each processing station. Two positioning rods of different diameters are inserted upward into two sets of anti-misalignment through holes 717 with different diameters, thereby preventing the positioning fixture 7 from being placed in the wrong direction.

[0056] The mounting plate 72 is provided with a first guide hole 721 and a second guide hole 722. The first guide hole 721 corresponds to both sides of the first slide 731, and the second guide hole 722 corresponds to both sides of the second slide 741.

[0057] The levers installed at each workstation pass upward through the second guide hole 722 and move along the second guide hole 722 to drive the second clamping block 744 to open or clamp. Under the guidance of the second guide hole 722, the second clamping block 744 can run more smoothly and with higher precision.

At the film-peeling station, the protective film on the glass cover is manually peeled off. The peeled glass cover is then placed back into the positioning fixture and transported to the next set of distribution and conveying platforms. S5. The first distribution mechanism distributes the fixtures on the first X-axis conveying assembly and the second X-axis conveying assembly on the last set of flipping and tearing film mechanism, and evenly conveys them to the multiple conveying production lines of the assembly mechanism. S6. The assembly mechanism assembles the glass cover onto the product body and, through the second distribution mechanism, transports the positioning fixtures from the multiple conveyor production lines of the assembly mechanism to the fixture unloading mechanism. S7. The fixture unloading mechanism removes the product from the positioning fixture and places it in the downstream equipment, and transports the empty positioning fixture to the fixture loading mechanism through the return conveyor belt on each mechanism.
