Description

Technical Field

[0001] This utility model relates to the field of mobile phone back cover production technology, and in particular to a fiberglass mobile phone back cover molding production line. Background Technology

[0002] With the rapid development of the smartphone market, the production process and efficiency of the phone back cover, as a key component, have a significant impact on the overall manufacturing level and production costs. Existing phone back cover molding equipment typically employs a discrete equipment layout, where each production stage (such as mold forming, clamping, and handling) is completed by independent equipment. First, the mold forming equipment heats the raw material and shapes it into the preliminary form of the back cover; then, a robotic arm or pneumatic device transfers the formed back cover to the next process; finally, further processing or finishing of the back cover is performed. While this decentralized design can meet basic production needs, the independent operation of each piece of equipment requires frequent workpiece transfers, equipment scheduling, and manual operation during production, which not only reduces production efficiency but also increases operational complexity and production costs.

[0003] In view of this, the inventor has conducted in-depth research on the above-mentioned problems and proposed the solution in this case. Utility Model Content

Detailed Implementation

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] Reference Figures 1 to 8 A fiberglass mobile phone back cover molding production line includes a machine base 10. The top surface of the machine base 10 is provided with a U-shaped tunnel conveyor line 11. The tunnel conveyor line 11 has the following stations arranged sequentially from the feeding direction to the discharging direction: a heating station 20 for heating the mold to a preset temperature, a feeding station 30 for feeding fiberglass sheets into the mold, a pressing station 40 for pressing the mold, an annealing station 50 for annealing the mold, a cooling station 60 for cooling the mold, and a material removal station 70 for removing the molded mobile phone back cover; several molds for molding mobile phone back covers are placed on the tunnel conveyor line 11. Each mold includes an upper mold plate and a lower mold plate that can be closed relative to each other. The lower mold plate has a concave mold adapted to the shape of the mobile phone back cover, and the upper mold plate has a convex mold adapted to the shape of the concave mold; multiple propulsion mechanisms 90 are arranged one-to-one with multiple inlets and outlets 111 on the tunnel conveyor line 11 to push the molds to circulate on the tunnel conveyor line 11.

[0032] In application, firstly, heating station 20 heats the mold to a preset temperature, such as 130-170℃, to ensure that the fiberglass material can be formed smoothly. Then, at feeding station 30, the fiberglass board is accurately fed into the mold. Next, the mold is pushed by pushing mechanism 90 into pressing station 40 for pressure forming, so that the fiberglass board in the mold is pressed into the preliminary shape of the mobile phone back cover. Then, the mold is pushed by pushing mechanism 90 into annealing station 50 and cooling station 60 for stress relief and cooling steps, thereby ensuring the strength of the formed back cover. Finally, at unloading station 70, the mobile phone back cover is taken out manually or by a robotic arm, thus completing the entire production process of the mobile phone back cover. Through this integrated production design, production efficiency is significantly improved, coordination time between equipment and manual intervention are reduced, production costs are saved, and the smoothness of mobile phone back cover production is greatly improved.

[0033] Reference Figures 1 to 8 The top of the heating station 20 is provided with at least one heating device for heating the mold. The heating device includes a heating plate (not shown in the figure) and a first cylinder (not shown in the figure) for driving the heating plate to approach or move away from the mold below. In this embodiment, the heating plate is composed of a resistance heater or an infrared heating tube. When heating the mold, the first cylinder drives the heating plate downward to abut against the mold. Then the heating plate starts to heat the mold until the mold temperature reaches the set value. After heating is completed, the first cylinder drives the heating plate away from the mold.

[0034] Reference Figures 1 to 7 Above both the feeding station 30 and the unloading station 70, there is a gripper mechanism 80 that can rise or fall and open or close the mold. The gripper mechanism 80 includes a vertically arranged second cylinder 81. The output end of the second cylinder 81 is fixedly connected to a mounting plate 82. The bottom surface of the mounting plate 82 is fixedly provided with a bidirectional cylinder 83 and two first slide rails 84. The two output ends of the bidirectional cylinder 83 are respectively fixedly connected to moving blocks 85. The top surface of each moving block 85 is provided with a first slider 851 that can move on the first slide rail 84. The bottom surface of each block 85 is fixedly connected with a vertically arranged clamping plate 86. In this embodiment, the first slide rail 84 is preferably an industrial heavy-duty slide rail that can withstand a large load. When feeding or unloading, the second cylinder 81 drives the mounting plate 82 to move up and down, and the bidirectional cylinder 83 drives the clamping plate 86 to open or close, thereby realizing the opening and closing operation of the gripper. When the gripper contacts the mold, the clamping plate 86 clamps the upper mold plate and lifts or lowers it, thereby completing the placement or removal of the material.

[0035] Reference Figures 1 to 9The molding station 40 includes multiple molding mechanisms, and at least one molding mechanism is equipped with a vacuuming mechanism for evacuating the mold. In this embodiment, the molding mechanism includes a vertically arranged hydraulic cylinder 41 and a pressure plate 42 fixedly connected to the output end of the hydraulic cylinder 41. The vacuuming mechanism includes a vacuum pump 43 arranged above any molding mechanism and a vacuum cover 44 sealed around the pressure plate of the molding mechanism. The top of the vacuum cover 44 is provided with a vacuum port 45. The vacuum pump 43 is connected to a flexible vacuum tube 46, and the end of the flexible vacuum tube 46 is sealed to the vacuum port 45. In application, the vacuum pump 43 is started and the air in the vacuum cover 44 is extracted through the flexible vacuum tube 46 to form a negative pressure environment, so that the mold can be more tightly fixed in the designated position during the molding process, thereby reducing bubbles and defects and improving molding accuracy.

[0036] Reference Figures 1 to 10 The annealing station 50 includes at least one vertically arranged third cylinder 51. The output end of the third cylinder 51 is fixedly connected to an annealing cover 52. The interior of the annealing cover 52 is provided with a heat insulation layer, which can be made of materials such as rock wool, glass wool, and ceramic fiber. The top of the annealing cover 52 is provided with at least one first fan 53 for cooling the mold, a hot air fan 54 for maintaining the mold temperature, and a first air outlet 55 for air circulation. In application, the mold is cooled by the first fan 53 until its temperature drops to 50°C. Then, the first fan stops working, and the hot air fan 54 is used to maintain the mold temperature within this range for a period of time, thereby achieving the stress relief effect on the glass fiber board inside the mold.

[0037] Reference Figures 1 to 11 The cooling station 60 includes at least one vertically arranged fourth cylinder 61. The output end of the fourth cylinder 61 is fixedly connected to a cooling cover 62. The top of the cooling cover 62 is provided with at least one second fan 63 for cooling the mold and a second air outlet 64 for air circulation. In application, the mold is cooled by the second fan 63 to ensure that the mold reaches the required temperature, facilitating subsequent material handling steps.

[0038] Reference Figures 1 to 11With the length direction of the machine platform 10 as the left and right direction, there are four propulsion mechanisms 90. The propulsion mechanisms 90 are respectively located at the bottom of the left side wall, the top of the left side wall, the top of the right side wall, and the bottom of the right side wall of the machine platform 10. The propulsion directions of the propulsion mechanisms 90 located on the same side are relatively perpendicular. Each propulsion mechanism 90 has a slot 12 on its base 10. The propulsion mechanism 90 includes two spaced mounting seats 91, a lead screw 92 between the two mounting seats 91, a sliding seat 93 on the lead screw 92, and a motor 94 for driving the lead screw 92 to rotate. The motor 94 is connected to the lead screw 92 via a coupling. Two spaced second slide rails 95 are provided on both sides of the lead screw 92. The bottom of the sliding seat 93 is provided with a second slider 931 that can slide on the second slide rails 95. The top of the sliding seat 93 is provided with a pusher 96 for abutting against the mold. The pusher 96 includes a vertical part 961 that extends through the slot 12 and a horizontal part 962 connected to the end of the vertical part 961. In this embodiment, the horizontal part 962 is parallel to the slot 12. In application, the motor 94 drives the lead screw 92 to rotate, causing the sliding seat 93 to slide along the second slide rails 95, thereby driving the pusher 96 to move along the slot 12, thus realizing the pushing of the mold.

[0039] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
