[0032] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0033] See also Figure 1-9The heating plate bending device in one embodiment of the present invention includes a frame 1 and a feeding mechanism 2, a bending mechanism 3, a guide mechanism 4 and a reset mechanism 5 arranged on the frame 1. The frame 1 is provided with a bending area 11 for bending the heating plate 8, and the heating plate 8 is bent in the bending area 11. The guide mechanism 4 is arranged between the feeding mechanism 2 and the bending area 11. The guide mechanism 4 includes a guide base 41 and a first guide groove 42 arranged on the guide base 41. One end of the first guide groove 42 faces the feeding mechanism 2, and the other end faces the bending area 11. The feeding mechanism 2 is used to drive the heating plate 8 through the first guide groove 42 and enter the bending area 11. The function of the first guide groove 42 is to prevent the heating plate 8 from deviating and prevent the deformation of the heating plate 8 during the bending process to ensure the bent shape;

[0034] The bending mechanism 3 includes a rotating base 32, a bending rod 31 provided on the rotating base 32, and a rotary motion module 33 for driving the rotating base 32 and the bending rod 31 to rotate. The rotating base 32 can be plate-shaped or rod-shaped. The rotating shaft of the bending rod 31 connecting the bending rod 31 and the rotary motion module 33 deviates from the rotation axis of the rotary motion module 33, that is, the axis of the bending rod 31 and the axis of the rotary motion module 33 are not concentric. The rotary motion module 33 drives the bending rod 31 to rotate, and the bending rod 31 bends the heating plate 8.

[0035] The reset mechanism 5 drives the bending rod 31 to leave and enter the bending area 11. When the bending rod 31 leaves the bending area 11, since the movement of the bending rod 31 will not affect the heating plate 8, the rotational motion module 33 can drive the bending rod 31 to rotate in the opposite direction and reset.

[0036] When the heating plate bending device is working, the feeding mechanism 2 drives the heating plate 8 through the first guide groove 42 and into the bending area 11, and the feeding mechanism 2 stops; the rotational motion module 33 drives the bending rod 31 to rotate, and the bending rod 31 contacts the heating plate 8, presses against and bends the heating plate 8, and the rotational motion module 33 stops. Then the reset mechanism 5 drives the bending mechanism 3 to move, driving the bending rod 31 to leave the bending area 11 and leave the part of the heating plate 8 that has just been bent. Since the movement of the bending rod 31 at this time will not affect the heating plate 8, the rotational motion module 33 drives the bending plate to rotate in the opposite direction and reset. The mechanism drives the unbent part of the heating plate 8 through the first guide groove 42 and into the bending area 11, and the reset mechanism 5 drives the bending mechanism 3 again, so that the bending rod 31 enters the bending area 11 again. The above working process is repeated in this way, and the heating plate 8 can be continuously bent. For the rotational motion trajectory of the bending rod 31, see Figure 5 As indicated by the arrow.

[0037] The heating sheet bending device can be used for automatic bending of the heating sheet 8, see Figure 10 The heating sheet 8 is a flat sheet structure at the beginning, which has a certain resistance. Figure 11 It can gather heat, thus achieving a three-dimensional heating space to make the heat more concentrated.

[0038] The heating plate bending device can complete the bending forming of the heating plate 8. For ultra-thin or ultra-fine metal heating plates 8, it can also achieve the advantages of precise bending forming size, high bending forming efficiency, controllable bending forming size, and low labor cost.

[0039] Preferably, the rotary motion module 33 is an electric motor or the like.

[0040] See also Figure 1-5 Preferably, the direction in which the heating plate 8 is driven by the feeding mechanism 2 is perpendicular to the rotation axis of the rotary motion module 33; and / or, the direction in which the heating plate 8 is driven by the feeding mechanism 2 is perpendicular to the direction in which the bending rod 31 is driven by the reset mechanism 5; and / or, the bending rod 31 is parallel to the rotation axis of the rotary motion module 33. Further preferably, Figure 1-9 The embodiment has the aforementioned three positional relationships at the same time, that is, the direction in which the feeding mechanism 2 drives the heating plate 8 to move is perpendicular to the rotation axis of the rotary motion module 33, the direction in which the feeding mechanism 2 drives the heating plate 8 to move is perpendicular to the direction in which the reset mechanism 5 drives the bending rod 31 to move, and the bending rod 31 is parallel to the rotation axis of the rotary motion module 33.

[0041] See also Figure 8 The first guide groove 42 is a fixed groove, and there is a small gap between the first guide groove and the heating plate 8, or the first guide groove is a clampable and loosenable groove, which clamps the heating plate 8 during bending and loosens the heating plate 8 during feeding, so that there is a gap between the heating plate 8 and the first guide groove.

[0042] In some embodiments, see Figure 4-5The first guide portion 431 and the second guide portion 432 are arranged in parallel, and a second guide groove 433 is formed between the first guide portion 431 and the second guide portion 432 for the heating plate 8 to pass through and clamp the heating plate 8; one end of the second guide groove 433 corresponds to the end of the heating plate 8 coming out of the first guide groove 42, so that the heating plate 8 can enter the second guide groove 433 after passing through the first guide groove 42, and the other end of the second guide groove 433 is arranged in the bending area 11, and the first guide portion 431 and / or the second guide portion 432 form a bending portion 4321 at the other end of the second guide groove 433, and the rotary motion module 33 drives the bending rod 31 to rotate, and the bending rod 31 presses against the heating plate 8 to approach the bending portion 4321, and the bending rod 31 and the bending portion 4321 press against the opposite sides of the heating plate 8 respectively to bend the heating plate 8. When the heating plate bending device is working, the feeding mechanism 2 drives the heating plate 8 through the first guide groove 42, the second guide groove 433 and into the bending area 11, and the feeding mechanism 2 stops; the reset mechanism 5 drives the bending rod 31 to enter the bending area 11, and the rotary motion module 33 drives the bending rod 31 to rotate. The bending rod 31 contacts the heating plate 8 and presses the heating plate 8 to move closer to the bending part 4321. The heating plate 8 is bent under the pressure of the bending rod 31 and the bending part 4321, and the rotary motion module 33 stops. Preferably, the first guide portion 431 and the second guide portion 432 protrude from the frame 1 in a boss shape. When the bending rod 31 presses against the heating plate 8 and approaches the bending portion 4321, the heating plate 8 is pressed against the bending portion 4321, that is, pressed against the side wall of the bending portion 4321. The bending rod 31 and the bending portion 4321 press against opposite sides of the heating plate 8, respectively. The heating plate 8 is bent by the combined action of the bending rod 31 and the bending portion 4321. In other embodiments, the guide mechanism 4 may also not include the bending chuck 43, and the heating plate 8 is bent by relying on the first guide groove 42 and the bending rod 31.

[0043] See also Figure 5 、 8 and 9. Preferably, the surface of the bending rod 31 and / or the bending portion 4321 in contact with the heating plate 8 is parallel to the rotation axis of the rotational motion module 33.

[0044] See also Figure 5 Preferably, when the bending rod 31 is located in the bending area 11, the radial distance between the bending portion 4321 and the rotation axis of the rotary motion module 33 is smaller than the radial distance between the bending portion 4321 and the rotation axis of the rotary motion module 33, so that when the bending rod 31 and the bending portion 4321 bend the heating sheet 8, the bending directions of the heating sheet 8 at the bending portion 4321 and the bending portion 4321 are opposite, so that the heating sheet 8 is bent into S. Figure 1-4Furthermore, the feeding mechanism 2 includes a clamping module 22 for clamping the heating plate 8 and a linear motion module 21 for driving the clamping module 22 to move linearly toward the first guide groove 42. Figure 1 The arrow indicates the feeding direction of the feeding mechanism 2. After the clamping module 22 clamps the heating plate 8, the linear motion module 21 drives the clamping module 22 and the heating plate 8 to move linearly through the first guide groove 42. Preferably, the clamping module 22 is a finger cylinder, also known as a pneumatic finger, for clamping the heating plate 8; the linear motion module 21 is a cylinder or motor that drives the clamping module 22 to move linearly.

[0045] See also Figure 9 Furthermore, the guide mechanism 4 and the bending area 11 are arranged on one side of the guide base 41, and the bending rod 31 is arranged on the other side of the guide base 41. A through hole 410 is provided on the guide base 41. The bending rod 31 passes through the through hole 410 to enter the bending area 11, that is, extends to the side of the guide base 41 where the guide mechanism 4 is located; the reset mechanism 5 drives the bending rod 31 to leave and enter the bending area 11 through the through hole 410.

[0046] Preferably, the reset mechanism 5 is connected to and drives the bending mechanism 3, driving the entire bending mechanism 3 together with the bending rod 31 to move. The reset mechanism 5 is a lifting mechanism connected to the bending mechanism 3. In this embodiment, see Figure 1 The lifting mechanism is used to drive the bending mechanism 3 to rise and the bending rod 31 to enter the bending zone 11, and to drive the bending mechanism 3 to descend and the bending rod 31 to leave the bending zone 11. In other words, the feeding mechanism 2 drives the heating plate 8 to feed and the bending rod 31 is in a lowered state when the feeding mechanism 2 drives the heating plate 8 to feed and the bending rod 31 is reset; or conversely, in other embodiments, the lifting mechanism is used to drive the bending mechanism 3 to descend and the bending rod 31 to enter the bending zone 11, and to drive the bending mechanism 3 to rise and the bending rod 31 to leave the bending zone 11. In other words, the feeding mechanism 2 drives the heating plate 8 to feed and the bending rod 31 is in an elevated state when the feeding mechanism 2 drives the heating plate 8 to feed and the bending rod 31 is reset. The lifting mechanism can be a cylinder or a motor.

[0047] See also Figure 2 、 6And 7, further, the bending mechanism 3 includes a limit member 6 provided on the rotating base 32 and a signal sensing module 7 provided on the frame 1 for sensing the position of the limit member 6. The limit member 6 is driven to rotate by the rotary motion module 33, approaching or moving away from the signal sensing module 7. The feeding mechanism 2 drives the heating plate 8 according to the signal of the signal sensing module 7, and the rotary motion module 33 drives the bending rod 31 to rotate according to the signal of the signal sensing module 7. Preferably, the limit member 6 can limit the rotation of the rotary motion module 33 to a certain angle, and the bending angle of the heating plate 8 can be adjusted by adjusting the angle. The signal sensing module 7 can sense the position of the limit member 6 and send a signal to the reset mechanism 5 to drive the bending mechanism 3 to move. The signal sensing module 7 is preferably a distance sensor.

[0048] See also Figure 5 The arrow in the figure shows the rotation direction of the bending rod 31. Preferably, the rotational motion module 33 can drive the bending rod 31 to rotate clockwise and counterclockwise, and the rotation does not exceed one circle.

[0049] In summary, the heating plate bending device can complete the automatic bending and forming of the heating plate 8. For ultra-thin or ultra-fine metal heating plates 8, it can also achieve the advantages of precise bending and forming dimensions, high bending and forming efficiency, controllable bending and forming dimensions, and low labor costs.
