Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0045] As described in the background art, since the back panel of a mobile phone is usually required to have high precision and surface quality, any defects in the demoulding process may affect the final quality of the product.

[0046] In order to solve this technical problem, the present invention provides a 3D composite plate forming hot bending device, which is used to solve the problem of difficult demolding between molds and molds, and between molds and plates.

[0050] The heat transfer and hot bending effect as well as the clamping process are made more stable and convenient by the heat conducting part 509 and the clamping groove 508. At the same time, the joint groove 510 allows the heat to pass through the protruding heat insulation plate 512 to effectively block the heat and prevent heat loss during the heating process. At the same time, the temperature change frequency is kept stable to prevent the hot bending part from being damaged due to excessive temperature changes.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0054] Example 1, please refer to Figure 6 , Figure 7 , Figure 8 and Fig. 9 A hot bending device for forming a 3D composite plate, the hot bending structure 5 also includes a mechanical arm 501 fixedly connected to the center point of the base 4, the mechanical arm 501 has a rotation function through a motor, a telescopic column 502 is connected to the mechanical arm 501, the end of the telescopic column 502 is fixedly connected to a rolling column 503, the rolling column 503 has a rotation function through the motor, a telescopic rod 504 is fixedly connected below the rolling column 503, and a mechanical hand 505 is fixedly connected to the end of the telescopic rod 504.

[0055] By clamping, the upper cover 506 and the lower cover 507 can be transported by clamping, so that the mold no longer needs to be transported manually, avoiding the situation where impurities are easily present inside the mold and the processing site, and dividing the space inside the frame 1 into two parts by partitioning to make the processing scene more reasonable.

[0056] The length of the joint groove 510 is consistent with the cross-sectional length of the heat insulation board 512 .

[0057] Please refer to Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14A hot bending device formed by 3D composite panels, the hot bending structure 5 also includes a heat transfer plate 511 fixedly connected to the bottom outer wall of the upper cover 506 and in contact with the heat conduction part 509, both sides of the upper cover 506 are fixedly connected with heat insulation plates 512, and a hot bending plate 513 for hot bending is fixedly connected to the bottom outer wall of the heat transfer plate 511.

[0058] The hot bending structure 5 also includes oblique grooves 514 opened on both sides of the narrow side of the lower cover 507. One group of oblique grooves 514 are two through grooves that gradually sink from both sides to the middle, and the other group of oblique grooves 514 are sliding grooves of the same shape and symmetrically arranged. A placement groove 5141 is opened on the lower cover 507.

[0059] Through the arc strip 5071 in the lower cover 507 and the hot bending plate 513 on the upper cover, the plate can be gradually attached and have arc edges during the extrusion and heating process at the upper and lower ends.

[0060] The hot bending structure 5 also includes an air column 515 fixedly connected to the inner wall at the bottom of the placement groove 5141, and spring telescopic rods 516 are fixedly connected at both ends of the air column 515. The inside of the air column 515 is slidably connected to a piston 517, and an air guide groove 5171 is opened inside the piston 517. The top of the piston 517 is fixedly connected to a hollow telescopic cylinder 518, and two blocking plates 519 are fixedly connected in the air guide groove 5171 of the piston 517, and a bellows 520 is fixedly connected to one side of the blocking plate 519.

[0061] It should be added that a gap needs to be reserved on the hollow telescopic cylinder 518 for the bellows 520 to pass through, and the gap needs to be larger than the diameter of the bellows 520 .

[0062] The hot bending structure 5 also includes a transmission block 521 fixedly connected to the spring telescopic rod 516, an inner air groove 522 is opened in the transmission block 521, and the end of the bellows 520 away from the blocking plate 519 is bent and fixedly connected to the transmission block 521 and communicated with the inner air groove 522. A single transmission block 521 is provided with a motion column 523, and a first drive motor 5231 is fixedly connected to the transmission block 521. The output end of the first drive motor 5231 is fixedly connected to the motion column 523 through a hollow rotating shaft and communicated. Fine grooves 524 are opened on both sides of the lower cover 507, and an air cushion 525 is provided on the motion column 523. The part where the air cushion 525 is connected to the motion column 523 is communicated. The air cushion 525 has an inflatable expansion part near the side of the upper cover 506, and the rest is a non-inflatable paper-like structure, and a single air cushion 525 is wound around the fine groove 524.

[0063] By connecting the upper and lower structures with the air cushion 525, the air cushion 525 serves as a connecting piece to make the upper cover 506 and the lower cover 507 become a whole, and at the same time, it is not easy for the upper cover 506 and the lower cover 507 to separate, avoiding the traditional method where the upper cover 506 and the lower cover 507 are easily separated too quickly after separation, resulting in damage to the plate.

[0064] Example 2 further optimizes the 3D composite plate forming hot bending device provided in Example 1. Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the extrusion device 6 includes a dust blocking plate 601 fixedly connected to the base 4, the dust blocking plate 601 does not contact the robot arm 501, a limit frame 602 is fixedly connected to the inner wall of the frame 1, a plurality of rollers 6021 are rotatably connected to the limit frame 602, a friction frame 603 is fixedly connected to the top outer wall of the dust blocking plate 601, and a processing plate 604 is fixedly connected to the frame 1.

[0065] The rolling column 503 generates a unidirectional movement force after being squeezed by the friction frame 603, so that the rolling column 503 moves after contacting between the friction frame 603 and the limit frame 602, so that it can drive the mold to be transported in the frame 1 and prevent impurities from entering the dust-free area.

[0066] Further, such as Figure 4 and Figure 5 As shown, the extrusion device 6 also includes an electric push rod 605 fixedly connected to the frame 1, a back plate 606 is fixedly connected to the frame 1, a plurality of groups of presses 607 are fixedly connected to the back plate 606, and a heating plate 608 is fixedly connected to the bottom of the press 607.

[0067] The pressing machine 607 and the heating plate 608 provide the upper cover 506 with the extrusion force and temperature required for heat bending, so that the heat bending process can be carried out.

[0068] The extrusion device 6 further comprises a sliding plate 609 slidably connected to the back plate 606 , and a plurality of second drive motors 610 are fixedly connected to the sliding plate 609 . The second drive motor 610 is fixedly connected to a push rod 611 via a coupling and a rotating shaft.

[0069] By adopting a repeated pushing method, the workpiece placed on the processing plate 604 can gradually move to one side, so that the clamping tool near the end can clamp the mold and will not hinder the downward movement of the press 607.

[0070] The use process of a 3D composite plate forming hot bending device provided by the present invention is as follows:

[0071] 1. When the device is in use, the upper cover 506 is clamped in the manipulator 505 through the clamping groove 508. At this time, the air cushion 525 is in a relaxed state, suspended between the upper cover 506 and the lower cover 507, and restricted by the moving column 523 and the upper cover 506, so that the upper cover 506 is fixed by the manipulator 505, and the lower cover 507 is pulled by the air cushion 525 and suspended below the upper cover 506. Figure 7 In the state shown, the operator manually delivers the plate into the recessed space of the lower cover 507, and the plate is received by the two moving columns 523. At this time, the air cushion 525 holding the lower cover 507 is used as a guide plate to enable the plate to better enter the space of the lower cover 507;

[0072] 2. After being placed in, the first driving motor 5231 starts to work. Since the part of the air cushion 525 passing through the fine groove 524 is subjected to the bending force in the vertical direction and the gravity of the lower cover 507, the moving column 523 first rolls up the air cushion 525 in the lower cover 507 and gradually moves it to both ends. Since the oblique groove 514 gradually moves upward from the middle to both ends, the transmission block 521 is pulled and moves to both sides. The bottom of the plate placed on the moving column 523 is subjected to the relative rotational force, so that the plate can be in the central position of the lower cover 507 when it falls. This action puts the plate in the central position to achieve a better effect of hot bending. When the transmission block 521 gradually moves to both sides, the piston 517 connected to it is lifted. At this time, the internal space of the air column 515 gradually increases and the bottom is in a closed state. At this time, negative pressure is generated to draw the gas in the air cushion 525 into the space. It should be added that Fig.10 The area indicated by the air cushion 525 is the expansion area of ​​the air cushion 525, which cannot pass through the thin groove 524 in the expanded state, further ensuring that when the plate does not fall to the bottom surface of the lower cover 507, the distance between the upper cover 506 and the lower cover 507 will not change, preventing the plate from being squeezed and damaged when it is not placed in a suitable position;

[0073] 3. When the transmission block 521 moves to both sides, the spring telescopic rod 516 is stretched and in a taut state. When the operator observes that the plate is in a suitable position, the gas in the air cushion 525 has been extracted so that the air cushion 525 can pass through the fine groove 524, which is equivalent to opening the first safety. At this time, the staff confirms that the plate is placed and then supports the lower cover 507 to make the 90-degree bending force disappear. Under the rolling action of the moving column 523, the upper cover 506 and the lower cover 507 are gradually brought closer to each other through the rolling of the air cushion 525. However, at this time, the moving column 523 is still under the hot bending plate 513 to prevent the plate from being damaged due to the distance being too close. When the upper cover 506 and the lower cover 507 are fully fitted, they move to the side of the upper cover 506 and the hot bending plate 513 and the heat insulation plate 512. At this time, under the action of the spring telescopic rod 516, it is completely stuck in this area and acts as a buckle to prevent the upper cover 506 and the lower cover 507 from detaching during the hot bending process.

[0074] 4. After the robot arm 501 transports the structure to the processing plate 604, it is bonded to the heating plate 608 through the heat conducting part 509 and is hot-bent under the action of the press 607. The structure is taken out by the robot arm 501 and the robot hand 505 and then brought to the manual operation area. The mold opening operation is required. The moving column 523 moves in the reverse direction to separate the air cushion 525 above it. The moving column 523 is located in a small position. The space is filled with a large number of irregular air cushions 525. After being squeezed, the internal space of the upper cover 506 and the lower cover 507 generates an outward squeezing force, so that the operator can quickly separate the upper and lower covers. Partial separation is performed. During the separation process, the moving column 523 is separated from the heat bending plate 513 and finally moves to the bottom of the heat bending plate 513. After separation, the moving column 523 moves to both sides of the heat bending plate 513 on the heat bending plate 513 under the action of the spring telescopic rod 516. When it moves to the bottom of the heat bending plate 513, it is restricted by the spring telescopic rod 516 to move to the middle and separate the plate attached to it, so that the plate can be taken out better. Even if it is not completely demoulded, the plate is peeled off in parallel, so that it can reduce the damage during peeling after it is manually taken out.

[0075] 5. Supplement: After the electric push rod 605 is driven, the sliding plate 609 pulls the upper part thereof to move with the second driving motor 610 and the push rod 611. When the push rod 611 is perpendicular to the back plate 606, it contacts the box-shaped structure formed by the upper cover 506 and the lower cover 507 on the processing plate 604, and moves unidirectionally under the action of the electric push rod 605, and returns to the state. Figure 5 After the state is reached, the electric push rod 605 pushes the push rod 611 back to its original position, so that the box-shaped structure on the processing plate 604 can move to the end of the dust blocking plate 601, which is convenient for the robot 505 to grab.
