Description

Technical Field

[0001] This invention relates to the field of mobile phone assembly equipment, and in particular to a mobile phone graphite sheet assembly equipment. Background Technology

[0002] During the mobile phone assembly process, graphite sheets need to be installed inside the phone to dissipate heat. To ensure a more secure assembly of the graphite sheets with the phone body, pressure needs to be applied to the surface of the graphite sheets. Traditional pressure application methods generally fall into two categories: one is to press a pressure block vertically downwards onto the object and maintain it for a certain period of time; the other is to use a pressure roller to roll back and forth along the surface of the object a certain number of times. However, for the pressure application of graphite sheets in mobile phones, if a vertically pressing pressure block is used, it is difficult to distribute the force evenly on the graphite sheet due to its large area, resulting in poor pressure application in some areas. If a roller is used for pressure application, the roller does not have enough operating space because the height of the phone's bezels is higher than the graphite sheet, making pressure application impossible. Therefore, to improve the pressure application effect of graphite sheets, it is necessary to develop a mobile phone graphite sheet assembly device to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a mobile phone graphite sheet assembly device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

The inner sides of the pressure blocks contact the middle mounting plate and the top frame. The upper inner side of the pressure blocks is provided with an inclined surface, which contacts the top frame. The middle mounting plate is provided with a mounting cavity in the middle.

[0010] Further description of the invention: The silicone plate includes a central pressure plate and end plates. The end plates are fixed on the left and right sides of the central pressure plate. The contour of the mounting cavity matches the contour of the central pressure plate and the end plates. The central pressure plate and the end plates are fixed in the mounting cavity. The outer end of the end plates corresponds to the space between the bottom frame and the top frame.

[0011] Further description of the present invention: The linkage film-tearing mechanism includes a mounting frame, a Y-axis drive assembly, a mounting plate, a second X-axis drive assembly, a Z-axis drive assembly, a rotary drive assembly, a linkage gripper assembly, and a recycling bin. The Y-axis drive assembly is fixed above the mounting frame, the mounting plate is fixed to the power output end of the Y-axis drive assembly, the second X-axis drive assembly is fixed to the mounting plate, the Z-axis drive assembly is fixed to the power output end of the second X-axis drive assembly, the rotary drive assembly is fixed to the power output end of the Z-axis drive assembly, the linkage gripper assembly is fixed to the power output end of the Z-axis drive assembly, and the recycling bin is fixed on the mounting frame and corresponds to the lower part of the linkage gripper assembly.

[0012] The linkage gripper assembly includes a mounting block, a film-tearing drive cylinder, a first connecting block, a buffer, a second connecting block, a first gripper, a second gripper, and a roller. The mounting block is vertically fixed below the rotary drive assembly and has a clearance groove. The film-tearing drive cylinder and the buffer are both fixed on the mounting block and correspond to the two sides of the clearance groove, respectively. The first connecting block passes through the clearance groove and one end is fixed to the power output end of the film-tearing drive cylinder. The second connecting block is fixed to the other end of the first connecting block. The first gripper is fixed below one end of the first connecting block. The mounting block has two sets of arc-shaped through holes with their centers coinciding. The upper end of the second gripper is slidably connected to both sets of arc-shaped through holes. The roller is rotatably mounted on the side of the second gripper. The second connecting block has a strip-shaped hole along the vertical direction, and the roller is slidably connected to the strip-shaped hole. The lower end face of the second gripper has a second adsorption through hole.

[0015] Further description of the present invention: A first adsorption through hole is provided on the clamping boss.

[0016] The beneficial effects of this invention are as follows: The mobile phone is transported from right to left on the assembly conveyor mechanism along with the carrier tray. At the right end of the assembly conveyor mechanism, a plasma fan removes static electricity from the mobile phone body to facilitate the subsequent assembly of components. The graphite sheet feeding mechanism feeds the graphite sheets. When the carrier tray reaches below the graphite sheet assembly robot, the graphite sheet assembly robot picks up the graphite sheet from the graphite sheet feeding mechanism and moves it to the CCD detection component for imaging and positioning. After positioning, the graphite sheet assembly robot assembles the graphite sheet onto the mobile phone. After the graphite sheet is installed on the mobile phone, it is transported sequentially to the pressure holding mechanism and the linkage film peeling mechanism along with the carrier tray, where the graphite sheet is pressure-held and the film is peeled off. During pressure holding, the protective film on the graphite sheet is positioned below the pressure holding partition assembly. The carrier plate rises to contact the silicone plate. Then, the lifting cylinder drives the top block to retract upwards, and the counterweight moves downwards under gravity, causing the rolling roller to contact the upper surface of the silicone plate. Next, the first X-axis drive assembly drives the movable bracket to move left and right, causing the rolling roller to reciprocate on the silicone plate in the left and right direction. The lower end contour of the silicone plate matches the contour of the graphite sheet, thus enabling the silicone plate to hold pressure on the graphite sheet. Because the rolling roller reciprocates and applies pressure to various parts of the silicone plate, the pressure holding on the graphite sheet is uniform and sufficient, avoiding insufficient pressure holding in local areas.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 9 As shown, a mobile phone graphite sheet assembly equipment includes a frame 1, an assembly conveying mechanism 2, a plasma fan 3, a CCD detection component 4, a graphite sheet feeding mechanism 5, a graphite sheet assembly robot 6, a pressure holding mechanism 7, and a linkage film tearing mechanism 8. The assembly conveying mechanism 2 is fixed on the frame 1 along the X-axis. The plasma fan 3 is fixed on the frame 1 and mounted above the right end of the assembly conveying mechanism 2. The CCD detection component 4 is fixed on the frame 1 and corresponds to the front side of the assembly conveying mechanism 2. The graphite sheet feeding mechanism 5 is fixed on the frame 1 and corresponds to the front side of the CCD detection component 4. The graphite sheet assembly robot 6 is mounted above the assembly conveying mechanism 2, the CCD detection component 4, and the graphite sheet feeding mechanism 5. The pressure holding mechanism 7 and the linkage film tearing mechanism 8 are both fixed on the frame 1 and mounted above the assembly conveying mechanism 2. The pressure holding mechanism 7 and the linkage film tearing mechanism 8 are sequentially located on the left side of the graphite sheet assembly robot 6.

[0031] The pressure holding mechanism 7 includes a pressure holding roller assembly 71 and a pressure holding partition assembly 72. The pressure holding roller assembly 71 includes a first mounting bracket 711, a first X-axis drive assembly 712, a movable bracket 713, a counterweight bracket 714, a guide column 715, a rolling roller 716, a lifting cylinder 717, and a top block. Two sets of first mounting brackets 711 are arranged along the front-rear direction. The first X-axis drive assembly 712 is fixed above the first mounting bracket 711. Both the front and rear ends of the movable bracket 713 are fixed to the first X-axis drive assembly 714. The power output end of the X-axis drive assembly 712 includes a counterweight bracket 714 positioned above the movable bracket 713, a guide post 715 fixed at its upper end below the counterweight bracket 714, a guide post 715 passing through the movable bracket 713, a rolling roller 716 rotatably mounted below the counterweight bracket 714, a lifting cylinder 717 fixed on the counterweight bracket 714 with its power output end facing downwards, and a top block fixed at the power output end of the lifting cylinder 717 and corresponding to the upper part of the movable bracket 713.

[0032] The pressure-holding partition assembly 72 includes a second mounting bracket 721, a fixing frame 722, and a silicone plate 723. The second mounting bracket 721 is fixedly disposed below the rolling roller 716, and the fixing frame 722 is fixed above the second mounting bracket 721. The fixing frame 722 is provided with a mounting cavity, which vertically penetrates the fixing frame 722. The silicone plate 723 is fixed in the mounting cavity.

[0033] The mobile phone is transported from right to left on the assembly conveyor 2 along with the carrier tray. At the right end of the assembly conveyor 2, the plasma fan 3 removes static electricity from the mobile phone body to facilitate the subsequent assembly of components. The graphite sheet feeding mechanism 5 feeds graphite sheets. When the carrier tray reaches below the graphite sheet assembly robot 6, the graphite sheet assembly robot 6 picks up the graphite sheet from the graphite sheet feeding mechanism 5 and moves it to the CCD detection component 4 for imaging and positioning. After positioning, the graphite sheet assembly robot 6 assembles the graphite sheet onto the mobile phone. After the graphite sheet is installed on the mobile phone, it is transported sequentially to the pressure holding mechanism 7 and the linkage film peeling mechanism 8 along with the carrier tray. The graphite sheet is then subjected to pressure holding and the protective film on the graphite sheet is peeled off. During pressure holding, the position of the mobile phone graphite sheet... Below the pressure-holding partition assembly 72, the carrier plate rises to contact the silicone plate 723. Then, the lifting cylinder 717 drives the top block to retract upwards, and the counterweight moves downwards under the action of gravity, so that the rolling roller 716 contacts the upper surface of the silicone plate 723. Next, the first X-axis drive assembly 712 drives the movable bracket 713 to move left and right, so that the rolling roller 716 reciprocates on the silicone plate 723 in the left and right direction. The lower end face contour of the silicone plate 723 matches the contour of the graphite sheet, so that the silicone plate 723 can hold pressure on the graphite sheet. Because the rolling roller 716 reciprocates to apply pressure to various parts of the silicone plate 723, the pressure on the graphite sheet is uniform and sufficient, avoiding insufficient pressure in some areas. After the pressure holding is completed, the lifting cylinder 717 drives the top block to move downward. The top block contacts the movable bracket 713 and lifts the counterweight bracket 714, thereby causing the rolling roller 716 to disengage from the silicone plate 723. A counterweight block of a specific weight can be installed on the counterweight bracket 714 according to the pressure holding requirements. During the lifting and lowering of the counterweight bracket 714, the guide column 715 slides vertically on the movable bracket 713 to ensure smooth lifting and lowering of the counterweight bracket 714.

[0034] The silicone plate 723 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 716 to the graphite sheet, resulting in better pressure retention.

[0035] The fixed frame 722 includes a bottom frame 7221, a middle mounting plate 7222, a top frame 7223, bolts 7224, springs 7225, and pressure blocks 7226. The bottom frame 7221 is fixed above the second mounting bracket 721. The middle mounting plate 7222 is positioned above the bottom frame 7221, and the top frame 7223 is positioned above the middle mounting plate 7222. The bolts 7224 pass through the pressure blocks 7226 and are threaded to the bottom frame 7221 at their ends. The springs 7225 are sleeved on the bolts 7224 and their inner sides contact the pressure blocks 7226. The inner sides of the pressure blocks 7226 contact the middle mounting plate 7222 and the top frame 7223. The upper inner side of the pressure blocks 7226 has a slope that contacts the top frame 7223. The middle mounting plate 7222 has a mounting cavity in its middle section.

[0036] Pushing the pressure block 7226 outwards facilitates placing the middle mounting plate 7222 and the top frame 7223 onto the bottom frame 7221. After releasing the pressure block 7226, under the action of the spring 7225, the inner side of the pressure block 7226 presses the middle mounting plate 7222 and the top frame 7223 towards the center. At the same time, the inclined surface on the pressure block 7226 presses the top frame 7223 downwards, thereby quickly fixing the middle mounting plate 7222.

[0037] The silicone plate 723 includes a central pressure plate 7231 and an end insert plate 7232. The end insert plate 7232 is fixed on the left and right sides of the central pressure plate 7231. The contour of the mounting cavity matches the contour of the central pressure plate 7231 and the end insert plate 7232. The central pressure plate 7231 and the end insert plate 7232 are fixed in the mounting cavity. The outer end of the end insert plate 7232 corresponds to the space between the bottom frame 7221 and the top frame 7223. The silicone plate 723 is placed directly in the mounting cavity, and the end of the end insert plate 7232 is pressed by the bottom frame 7221 and the top frame 7223, thereby quickly fixing the silicone plate 723 onto the central mounting plate 7222.

[0038] The linkage film-tearing mechanism 8 includes a mounting frame 81, a Y-axis drive assembly 82, a mounting plate 83, a second X-axis drive assembly 84, a Z-axis drive assembly 85, a rotary drive assembly 86, a linkage gripper assembly 87, and a recycling bin 88. The Y-axis drive assembly 82 is fixed above the mounting frame 81, the mounting plate 83 is fixed to the power output end of the Y-axis drive assembly 82, the second X-axis drive assembly 84 is fixed on the mounting plate 83, the Z-axis drive assembly 85 is fixed to the power output end of the second X-axis drive assembly 84, the rotary drive assembly 86 is fixed to the power output end of the Z-axis drive assembly 85, the linkage gripper assembly 87 is fixed to the power output end of the Z-axis drive assembly 85, and the recycling bin 88 is fixed on the mounting frame 81 and corresponds to the lower part of the linkage gripper assembly 87.

[0039] The linkage gripper assembly 87 includes a mounting block 871, a film-tearing drive cylinder 872, a first connecting block 873, a buffer 874, a second connecting block 875, a first gripper 876, a second gripper 877, and a roller 878. The mounting block 871 is vertically fixed below the rotary drive assembly 86. The mounting block 871 is provided with a clearance groove 8711. The film-tearing drive cylinder 872 and the buffer 874 are both fixed on the mounting block 871 and correspond to the two sides of the clearance groove 8711, respectively. The first connecting block 873 passes through the clearance groove 8711 and one end is fixed to the power output of the film-tearing drive cylinder 872. At one end, the second connecting block 875 is fixed to the other end of the first connecting block 873, the first gripper 876 is fixed below one end of the first connecting block 873, the mounting block 871 has an arc-shaped through hole 8712, two sets of arc-shaped through holes 8712 are provided and their centers coincide, the upper end of the second gripper 877 is slidably connected to both sets of arc-shaped through holes 8712, the roller 878 is rotatably mounted on the side of the second gripper 877, the second connecting block 875 has a strip hole 8751 along the vertical direction, the roller 878 is slidably connected to the strip hole 8751, and the lower end face of the second gripper 877 has a second adsorption through hole.

[0040] When it is necessary to peel the protective film off the material, the protective film is on the upper surface of the material and has a tear-off point protruding from the material. The Z-axis drive assembly 85 drives the linkage gripper assembly 87 to descend. The second suction through hole of the second gripper 877 connects to the air extraction device and adsorbs the tear-off point of the protective film. The rotation drive assembly 86 drives the mounting plate to rotate, causing the second gripper 877 to rotate a certain angle towards the material, thus peeling off the edge of the protective film. Then, the film-peeling drive cylinder 872 drives the first connecting block 873 to move closer to the second gripper 877, while simultaneously driving the second connecting block 875 to move. The roller 878 moves downward in the strip hole 8751, thereby driving the second gripper 877 to move within the arc-shaped through hole 8712. Sliding, under the action of the two sets of arc-shaped through holes 8712, the second gripper 877 rotates around the center of the arc-shaped through hole 8712. The lower end of the second gripper 877 moves closer to the first gripper 876, so that the first gripper 876 and the second gripper 877 clamp the protective film. At this time, the lower end of the second gripper 877 is higher than the upper surface of the material due to rotation. The second X-axis drive assembly 84 drives the linkage gripper assembly 87 to move laterally, completely tearing off the protective film. Then, through the Y-axis drive assembly 82 and the rotation drive assembly 86, the protective film is moved to the top of the recycling box 88 and released, falling into the recycling box 88 for recycling. Its advantage is that it can not only improve the efficiency of tearing the film, but also does not damage the material.

[0041] The first gripper 876 has a clamping part 8761 at its lower end. The lower end of the clamping part 8761 is inclined toward the second gripper 877. After the film-tearing driving cylinder 872 simultaneously drives the first gripper 876 and the second gripper 877 to approach and clamp the protective film, the lower end face of the second gripper 877 fits against the inclined end face of the clamping part 8761, improving the clamping firmness.

[0042] The first gripper 876 is provided with multiple sets of gripping protrusions 8762. The multiple sets of gripping protrusions 8762 are evenly distributed on the gripping part 8761 in the vertical direction and correspond to the side close to the second gripper 877. The gripping protrusions 8762 can increase the pressure of the first gripper 876 on the protective film and increase the friction, thereby making the gripping more secure.

[0043] The clamping boss 8762 is provided with a first adsorption through hole, which is connected to the air extraction device. After the first gripper 876 clamps the protective film, the first adsorption through hole adsorbs the protective film, thereby improving the clamping firmness of the protective film.

[0044] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
