Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0046] like Figures 1 to 12 As shown in the figure, this is an embodiment of the present invention, which relates to a graphite sheet assembly mechanism, including a mechanism body 10. The mechanism body 10 includes a pressing device 20, a positioning device 30 disposed below the pressing device 30, and a conveying device 40 for conveying the positioning device 30. The pressing device 20 includes a bracket 21, a pressing assembly 50 connected above the bracket 21, and a lifting assembly 60 disposed below the positioning device 30. The pressing assembly 50 is used for pressing the graphite sheet with the product, and the lifting assembly 60 is used for driving the lifting and lowering of the positioning device 30.
[0047] Furthermore, the pressing assembly 50 includes a connecting plate 51, a first pressing block 52 and a second pressing block 53, a first pressing cylinder 54, a second pressing cylinder 55, a third pressing cylinder 56, and a fourth pressing cylinder 57. The first pressing block 52 and the second pressing block 53 are respectively disposed at the bottom of the connecting plate 51. In this embodiment, two pressing stations are provided around the first pressing block 52 and the second pressing block 53, which can perform two sets of pressing operations simultaneously, thereby improving processing efficiency. The first pressing cylinder 54 is disposed between the first pressing block 52 and the second pressing block 53. The second pressing cylinder 55, the third pressing cylinder 56, and the fourth pressing cylinder 57 are respectively disposed around the first pressing block 52 and the second pressing block 53. The first pressing cylinder 54, the second pressing cylinder 55, the third pressing cylinder 56, and the fourth pressing cylinder 57 are disposed below the connecting plate 51. Specifically, the first pressing cylinder 54, the second pressing cylinder 55, the third pressing cylinder 56 and the fourth pressing cylinder 57 press the graphite sheet on the product in four directions respectively, thereby improving the bonding accuracy between the graphite sheet and the product.
[0048] Furthermore, a first sliding groove 541 is connected below the first pressing cylinder 54, and a first slider 542 is movably connected to the first sliding groove 541. First pressing claws 543 are connected to both ends of the first slider 542, and a first pressing foot 544 is connected to the bottom of the first pressing claw 543. Specifically, the first pressing cylinder 54 is a finger cylinder, capable of pressing materials at two workstations simultaneously, reducing space occupation and improving processing efficiency. A second pressing claw 551 is connected to the output end of the second pressing cylinder 55, and a second pressing foot 552 is connected to the bottom of the second pressing claw 551. The third pressing cylinder 56... The output end of the first pressing cylinder 55 is connected to a third pressing claw 561, and the bottom of the third pressing claw 561 is connected to a third pressing foot 562; the output end of the fourth pressing cylinder 57 is connected to a fourth pressing claw 571, and the bottom of the fourth pressing claw 571 is connected to a fourth pressing foot 572. In this embodiment, the second pressing cylinder 55, the third pressing cylinder 56, and the fourth pressing cylinder 57 are all side-rail type slide cylinders. When pressing is required, the cylinder drives the pressing claw in the opposite direction to the pressing block, so that the pressing foot abuts against the graphite sheet and presses it. After pressing is completed, the cylinder drives the pressing claw in the direction of the pressing block, so that the pressing foot moves away from the graphite sheet, thereby further improving the bonding accuracy of the graphite sheet.
[0049] Furthermore, the first pressing foot 544, the second pressing foot 552, and the fourth pressing foot 572 are all J-shaped pressing feet, and the third pressing foot 562 is a trapezoidal pressing foot. Specifically, pressing feet with different structures are selected according to the shape of the material's corners. In this embodiment, the bottom arc surface of the J-shaped pressing foot and the trapezoidal pressing foot are matched with the corners of the material, making the graphite sheet fit more tightly with the corners of the product and effectively improving the bonding accuracy of the graphite sheet.
[0050] Furthermore, the lifting assembly 60 includes an L-shaped connecting block 61, a lifting cylinder 62 connected to one side of the L-shaped connecting block 61, a dual-axis piston rod 63 movably connected to the lifting cylinder 62, and a lifting plate 64 connected to the upper end of the dual-axis piston rod 63. The lifting plate 64 is connected to the bottom of the positioning device 30. Specifically, the lifting assembly 60 is a side-rail type sliding table cylinder, which is used to lift the positioning device 30 to facilitate the material to contact and press with the pressing assembly 50. After pressing is completed, the lifting assembly 60 lowers the positioning device 30 and transports it to the next workstation via the conveying device 40, which is highly practical.
[0051] Furthermore, the positioning device 30 includes a positioning plate 31, a plurality of positioning slots 32 disposed above the positioning plate 31, and a positioning component 70 disposed on one side of the positioning slots 32. The bottom of the positioning plate 31 abuts against the top of the lifting plate 64. Specifically, the positioning device 30 enables the material to be accurately positioned and fixed in the positioning slots 32, ensuring the stability and accuracy of the material during the assembly process and avoiding assembly errors caused by positional deviations.
[0052] Furthermore, the positioning component 70 includes a positioning gripper 71, a plurality of guide posts 72 connected to the rear of the positioning gripper 71, a positioning base 73 connected to the rear of the guide posts 72, and a positioning guide rail 74 movably connected to the positioning base 73. A hinge post 75 is connected between the positioning gripper 71 and the positioning base 73. The hinge post 75 is used to hinge the positioning gripper 71 and the positioning base 73. An elastic element 76 is connected to the rear of the positioning base 73, and an abutment block 77 is connected to the rear of the elastic element 76. Specifically, the positioning assembly 70 is provided with multiple sets to facilitate the simultaneous assembly of multiple sets of materials and improve efficiency; it is equipped with positioning grippers 71, guide posts 72, and positioning bases 73. Elastic elements 76 are used to apply clamping force to the positioning base 73 toward the positioning slot 32. Abutment blocks 77 are installed on the positioning plate 31. When the material is placed in the positioning slot 32, the positioning grippers 71 clamp and position the material. Positioning guide rails 74 and hinge posts 75 are provided. There is an movable gap between the positioning grippers 71 and the positioning base 73, which allows the positioning grippers 71 and the positioning base 73 to move relative to each other, while ensuring the reliability and stability of clamping and positioning, and ensuring that the material will not loosen or shift during operation.
[0053] Furthermore, the positioning gripper 71 has a clamping groove 78 on the side facing the positioning slot 32. Specifically, the clamping groove 78 is designed to accommodate products of different sizes or shapes and to ensure the firmness and stability of the clamping.
[0054] Furthermore, the conveying device 40 includes a conveying frame 41, conveyor belts 42 respectively disposed on both sides inside the conveying frame 41, and a conveying motor 43 for driving the conveyor belts 42. Several limiting components 80 are provided in the center of the interior of the conveying frame 41. Specifically, the conveying device 40 is used to transport multiple sets of positioning devices 30, realizing automated production line transportation, and is highly practical.
[0055] Further, the limiting assembly 80 includes a limiting wheel 81, a connecting block 82 connected to the limiting wheel 81, a lifting rod 83 connected to the bottom of the connecting block 82, a drive cylinder 84 connected to the lower end of the lifting rod 83, and a mounting block 85 for connecting to the conveying frame 41. The limiting wheel 81 is inserted with a pin 86, and the limiting wheel 81 is movably connected to the connecting block 82 through the pin 86. A limiting spring 87 is wound around the pin 86. Multiple sets of limiting assemblies 80 are provided to lock and limit the positioning device 30. When the drive cylinder 84 lifts the lifting rod 83, the lifting rod 83 lifts the limiting wheel 81, and the positioning device 30 can pass through. When the drive cylinder 84 descends, it drives the lifting rod 83 to descend, and the limiting wheel 81 rises under the action of the limiting spring 87 to block the positioning device 30.
[0056] The present invention includes a pressing device 20, a positioning device 30, and a conveying device 40. During operation, the conveying device 40 transports the positioning device 30 to below the lifting component 60 of the pressing device 20. At this time, the lifting component 60 lifts the positioning device 30, so that the material placed in the positioning device 30 comes into contact with the pressing component 50. The first pressing block 52 and the second pressing block 53, the first pressing cylinder 54, the second pressing cylinder 55, the third pressing cylinder 56, and the fourth pressing cylinder 57 in the pressing component 50 press the graphite sheets inside the material, thereby further improving the bonding accuracy between the graphite sheets and the material.
[0057] The above description merely illustrates preferred technical solutions of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
