Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to an automated production line for SMC composite material molding. Background Technology

[0002] SMC (Silicone Molding Compound) is a fiberglass material. Before processing, it is characterized by its softness, tendency for layers to stick together, strong pungent odor, and harsh working environment. After compression, it becomes a hard solid. These characteristics make processing difficult and can harm workers. When SMC sheets are used in molding production, the roll needs to be unrolled, the film torn off, flattened, and cut into specific lengths. Then, according to the material requirements of each molding die, a measured amount of SMC sheet is weighed and fed into the mold cavity for molding.

[0003] Therefore, it is necessary to design an automated production line for SMC composite material molding using SMC sheets as raw materials to meet the automated molding requirements of different molding products.

[0026] Example: This embodiment discloses an automated production line for SMC composite material molding.

[0027] like Figure 1 and Figure 2 As shown, the SMC composite material molding automated production line includes a material bin 1, a cutting machine 2, a first conveying mechanism 3, a stacking mechanism 4, a hydraulic press 6, and a second conveying mechanism 8 arranged sequentially from the front end to the rear end.

[0028] exist Figure 1 In the embodiments shown in the other figures, the direction pointed to by arrow X is the front end of the production line, the opposite direction pointed to by arrow X is the rear end of the production line, the direction pointed to by arrow Y is the left side of the production line, the opposite direction pointed to by arrow Y is the right side of the production line, the direction pointed to by arrow Z is the upper end of the production line, and the opposite direction pointed to by arrow Z is the lower end of the production line.

[0029] Sheet 11 is placed in hopper 1. For example... Figure 1 As shown, specifically, the SMC sheet 11 is folded and placed inside the material box 1, which increases the space utilization rate inside the material box 1 and facilitates the continuous feeding of the SMC sheet 11 by the cutting machine 2.

[0030] The cutting machine 2 is configured to receive the sheet 11, cut the sheet 11 into a pre-defined shape, and then discharge it to the first conveying mechanism 3. The cutting machine 2 uses a commercially available laser cutting machine 2, which can accurately cut out the pre-defined shape.

[0031] The first conveying mechanism 3 is configured to convey the material sheet towards the rear end. For example... Figure 3 As shown, exemplarily, the first conveying mechanism 3 includes a first platform 31 disposed on the ground and a plurality of first conveyor belts 32 disposed parallel to and spaced apart on the first platform 31. Both the first platform 31 and the first conveyor belts 32 are arranged in the front-to-back direction. The first platform 31 is located at the rear end of the cutting machine 2, and the upper end of the first conveyor belts 32 is flush with the lower end of the discharge port of the cutting machine 2. The first conveyor belts 32 are spaced apart in the left-to-right direction to facilitate the needles of the needle-punching grippers 53 to pass through the material sheet and extend into the interval to grip the material sheet.

[0032] like Figure 4 As shown, preferably, a weighing mechanism 33 is also provided between the first conveyor belt 32 and the first machine platform 31. The weighing mechanism 33 includes fixing blocks 332 disposed at the four corners of the first machine platform 31, weighing sensors 331 disposed on the fixing blocks 332, and a support portion 334 disposed on the upper end of the first machine platform 31. The fixing blocks 332 do not extend below the detection end of the weighing sensors 331. The support portion 334 can slide up and down relative to the first machine platform 31, and the lower end of the support portion 334 is supported on the four weighing sensors 331. Specifically, the first conveyor belt is mounted on the support portion 334. The weighing mechanism 33 also includes several limiting rods 333 and four sliding rods 335. The limiting rods 333 and the sliding rods 335 are vertically arranged. The sliding rods 335 are fixed to the lower end of the support portion 334 and slide through the detection end of the weighing sensors 331 to ensure that the support portion 334 can slide up and down smoothly when weighing. The limiting rod 333 is fixed to the upper end of the first machine base 31, and its position corresponds to the lower end of the support part 334, limiting the descent distance of the support part 334 to protect the weighing sensor 331 from exceeding its range. The weighing sensor 331 detects the weight of the currently cut material. When the weight of the currently transported material does not meet the specified weight, the cutting machine 2 will compensate in the subsequent batch of the same material to ensure that the weight of the product meets the standard.

[0033] A first robotic arm 51 is provided on the side of the stacking mechanism 4. The end of the first robotic arm 51 has a first fixture 52 that can move along the X, Y, and Z axes.

Figure 1 and Figure 3As shown, exemplarily, the stacking mechanism 4 includes a third platform 41, which is disposed on the ground and located at the rear end of the first platform 31. Several support rods 42 are disposed on the third platform 41, parallel to the left-right direction and spaced apart in the front-back direction. Material sheets are stacked on the support rods 42, facilitating the penetration of the needles of the needle-piercing grippers 53 into the gaps to grasp the material sheets. The first robotic arm 51 can be a commercially available three-axis robotic hand. The first fixture 52 includes a first frame, with several needle-piercing grippers 53 arranged in a square pattern at the lower end of the first frame. Specifically, the first frame includes two parallel first rods 521 of the same height, and several parallel second rods 522 of the same height, spaced apart at the lower end of the first rods 521. The first rods 521 and second rods 522 are perpendicular to each other. The needle-piercing grippers 53 are commercially available V-shaped needle-piercing suction cups.

[0034] Hydraulic press 6 is configured to hot-press stacked sheets to obtain the finished product. For example... Figure 5 As shown, exemplarily, the hydraulic press 6 includes a frame 61 mounted on the ground, located at the rear end of the third machine platform 41. The frame 61 has a hollow structure, with a worktable 63 located at the lower end inside. A slider 62 is also installed inside the frame 61, positioned above the worktable 63 and capable of sliding up and down within the frame 61. A lower mold 64 is mounted on the worktable 63, and an upper mold is mounted below the slider 62. Heating elements are installed within both the upper and lower molds 64. The slider 62 drives the upper mold to descend and close with the lower mold 64, pressing the stacked sheets into a finished product. Specifically, the heating elements are heating wires installed within the upper and lower molds 64.

[0035] A second robotic arm 71 is also provided between the hydraulic press 6 and the second conveying mechanism 8. The end of the second robotic arm 71 has a second fixture 72 that can move along the X, Y, and Z axes. The second fixture 72 is configured to grip the finished product and place it onto the second conveying mechanism 8. Figure 5 As shown, exemplarily, the second fixture 72 includes a second frame 721, with a plurality of vacuum suction cups 73 mounted on the lower end of the second frame 721, the vacuum suction cups 73 being arranged in a square pattern. Specifically, vertical rods 722 are circumferentially spaced at the lower end of the second frame 721, and the vacuum suction cups 73 are disposed on the sides of the vertical rods 722.

[0036] The second conveyor mechanism 8 is configured to convey finished products to the side. For example... Figure 6 As shown, exemplarily, the second conveying mechanism 8 includes a second platform 81 and a second conveyor belt 82 disposed on the second platform 81, the second platform 81 being located at the rear end of the frame 61. Specifically, the first conveyor belt 32 and the second conveyor belt 82 are commercially available belt conveyors. Preferably, the second conveying mechanism 8 is perpendicular to the first conveying mechanism 3, reducing the length of the production line and saving space.

[0037] like Figure 1 and Figure 6 As shown, the SMC composite material molding automated production line further includes a protective net 9. The protective net 9 is fixed to the ground and surrounds the material bin 1, cutting machine 2, first conveying mechanism 3, stacking mechanism 4, hydraulic press 6, and second conveying mechanism 8. A roller shutter door 91 is installed on the side of the protective net 9 near the material bin 1. A through hole 92 is also provided on the side of the protective net 9, through which the second conveying mechanism 8 passes and extends. The protective net 9 restricts personnel from entering and exiting the production line, protecting their safety.

[0038] In this embodiment, the cutting machine 2 receives the sheet 11 from the material box 1 and cuts it into a set shape. The sheet is then conveyed to the designated position by the first conveying mechanism 3. The first robotic arm 51 drives the first fixture 52 to stack the sheet onto the stacking mechanism. After stacking, the sheet is moved as a whole to the hydraulic press 6 for hot pressing to form a finished product. The second robotic arm 71 then drives the second fixture 72 to move the finished product to the second conveying mechanism 8 and send it out of the production line. This achieves automated molding of SMC composite materials, with a simple structure and convenient installation.
