[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] See also Figures 1 to 10 The embodiment of the present application provides a bending module for bending small strip-shaped parts, comprising: a supporting platform 1 , a first pressing block 2 , a suction portion 3 and a second driving member 4 .

[0039] The supporting platform 1 is horizontally arranged. The first pressing block 2 is arranged to move in the vertical direction Z. The first pressing block 2 is located above the supporting platform 1. Figure 3 As shown, the two suction parts 3 are symmetrically arranged. The two suction parts 3 are located on both sides of the carrier 1 in the first direction X. The suction part 3 includes a first driving member 31 and a suction surface 32 for sucking parts. The suction part 3 has a first position and a second position. Figure 1 and Figure 2 As shown, when the suction portion 3 is located at the first position, the two suction surfaces 32 are arranged horizontally upward. Figure 5 and Figure 6 As shown, when the suction part 3 is in the second position, the two suction surfaces 32 are arranged vertically opposite to each other. The suction surface 32 is provided with a negative pressure suction hole 33, a fixed stopper 34 and a movable stopper 35. Figure 7As shown, the fixed stopper 34 and the movable stopper 35 protrude from the suction surface 32 and are spaced apart in the second direction Y. The first driving member 31 is connected to the movable stopper 35 and is configured to drive the movable stopper 35 to move in the second direction Y. The first direction X, the second direction Y, and the vertical direction Z are mutually perpendicular, with the first direction X and the second direction Y being two directions perpendicular to each other in a horizontal plane. The second driving member 4 is connected to the suction portion 3 and is configured to drive the suction portion 3 to rotate and switch between the first position and the second position.

[0040] The bending module provided in this embodiment for bending small strip-shaped parts has two suction sections 3 spaced apart in a first direction X. A suction surface 32 is provided with negative pressure suction holes 33, fixed stops 34, and movable stops 35. The negative pressure suction holes 33 allow for negative pressure suction on the part, while the fixed stops 34 and movable stops 35 secure the part in a second direction Y, further securing the part. The suction section 3 moves the part onto the support platform 1 and secures the middle portion of the part to the support platform 1 using a first pressure block 2. A second driving member 4 drives the suction section 3 to rotate, thereby rotating the remaining portion of the part (i.e., the portions at both ends of the part) except for the portion pressed by the first pressure block 2, thereby achieving part bending. This allows for convenient and efficient part bending. The part is fixed only by the supporting platform 1, the first pressure block 2, the negative pressure suction hole 33, the fixed stopper 34 and the movable stopper 35. These structures remain relatively stationary with the part, and no relative displacement is generated between the mold and the part. Moreover, the suction portion 3 for driving the part to bend only acts on one surface of the part, rather than clamping its two surfaces, thereby avoiding damage to the part and protecting the part.

[0041] In this embodiment, if Figure 8 As shown, there are at least two negative pressure suction holes 33, spaced apart in the third direction W. The third direction W is perpendicular to the second direction Y and parallel to the suction surface 32. The at least two negative pressure suction holes 33 allow for effective negative pressure suction of the part. The fixed stopper 34 and the movable stopper 35 secure the part in the second direction Y, providing a stable and reliable fixation.

[0042] Specifically, the first drive member 31 is preferably a pneumatic cylinder to accommodate the securing of small parts. In the embodiments of this application, small parts are strip-shaped parts approximately 1 cm to 5 cm in length and 1 mm to 5 mm in width, and are extremely thin. When the first drive member 31 controls the movement of the movable stop 35, it is necessary to control the force exerted by the movable stop 35 on the part to prevent excessive pressure in the second direction Y from causing deformation of the part.

[0043] like Figure 9 and Figure 10As shown, a first air path 36 and a second air path 37 are provided in the suction portion 3. The first air path 36 is connected to the first driving member 31 and is used to drive the movable end of the first driving member 31 to move in the second direction Y. The second air path 37 is connected to the negative pressure suction hole 33. The second air path 37 includes a first portion 371 extending along the second direction Y and a second portion 372 extending along the third direction W. The second portion 372 is located directly below the negative pressure suction hole 33. The first air path 36 and the first portion 371 are spaced apart in the third direction W, which fully, effectively and reasonably utilizes the space of the suction portion 3 and avoids air path interference.

[0044] like Figure 7 As shown, the movable stopper 35 is provided with a blocking surface 351 and an avoidance surface 352 connected to each other. The blocking surface 351 faces the fixed stopper 34 and is perpendicular to the second direction Y, and can cooperate with the fixed stopper 34 to clamp the parts. The avoidance surface 352 is set at an angle, and the distance between the avoidance surface 352 and the supporting platform 1 gradually increases in the direction away from the suction surface 32, so that Figure 2 and Figure 6 As shown, the avoidance surface 352 can avoid the second pressing block 5 described below to avoid interference.

[0045] In this embodiment, the suction portion 3 is provided with a receiving groove 38 for accommodating the first driving member 31. A fixing block 39 is provided above the receiving groove 38 for fixing the first driving member 31 to prevent the first driving member 31 from falling out of the receiving groove 38. The fixing block 39 is positioned at one end adjacent to the movable stopper 35 in the second direction Y to limit the movable stopper 35.

[0046] Specifically, when the suction part 3 is located at the first position, the suction surface 32 is aligned with the bearing surface of the bearing platform 1, so that the two suction parts 3 can move the strip-shaped parts onto the bearing platform 1. Figure 6 As shown, when the suction part 3 is located at the second position, the suction surface 32 is located below the bearing surface. At this time, the suction part 3 has driven the two ends of the part to rotate 90 degrees, completing the bending operation.

[0047] In this embodiment, the bending module also includes two second pressing blocks 5 that move in the first direction X and are arranged opposite to each other. When the suction portion 3 is in the second position, the suction surface 32 is located below the second pressing block 5. The two second pressing blocks 5 are respectively in contact with the two ends of the support platform 1 in the first direction X, and are used to apply a certain amount of pressure to the corners of the bent part to ensure a good bending effect of the part. The two ends of the support platform 1 in the first direction X can be designed with rounded corners of different sizes as needed, and the side of the second pressing block 5 facing the support platform 1 is correspondingly designed with a shape that matches the rounded corners, ensuring that after the second pressing block 5 presses the part, the part, the support platform 1, and the second pressing block 5 are tightly fitted.

[0048] Specifically, such as Figure 4 As shown, the bending module also includes a first mounting seat 6, on which a first slide rail 7 extending along the second direction Y and a second slide rail 8 extending along the first direction X are provided. The supporting platform 1 is fixedly arranged on the first mounting seat 6. A first slider 9 is slidably connected to the first slide rail 7. The first slider 9 is provided with a third slide rail 10 extending along the vertical direction Z. The first pressure block 2 is slidably connected to the third slide rail 10, so that the first pressure block 2 can move both along the vertical direction Z and along the second direction Y, so as to adjust the position of the part for placement and fixation. The second pressure block 5 is slidably connected to the second slide rail 8, so that the second pressure block 5 can move along the first direction X. By providing the first mounting seat 6, an installation position can be provided for the supporting platform 1, the first pressure block 2 and the second pressure block 5.

[0049] like Figure 1 As shown, a second slider 11 is slidably connected to the second slide rail 8. A fourth slide rail 12 extending along the first direction X is provided on the second slider 11. The second pressure block 5 is slidably connected to the fourth slide rail 12. The end of the second pressure block 5 away from the support platform 1 is elastically connected to the second slider 11 via a spring 13. The ends of the spring 13 in the first direction X abut against the second pressure block 5 and the second slider 11, respectively. By providing the fourth slide rail 12 and spring 13, the second pressure block 5 can prevent excessive pressure on the bent component, thereby preventing damage to the component.

[0050] In this embodiment, the bending module further includes a fifth slide rail 14 extending in the first direction X. The fifth slide rail 14 is located on one side of the first mounting seat 6 in the second direction Y, providing a mounting location for the suction unit 3. A second mounting seat 15 is slidably connected to the fifth slide rail 14. The second mounting seat 15 is provided with a sixth slide rail 16 extending in the second direction Y. A third mounting seat 17 is slidably connected to the sixth slide rail 16. The suction unit 3 and the second drive member 4 are connected to the third mounting seat 17, allowing the suction unit 3 and the second drive member 4 to move as a whole in the first direction X to transport parts before and after bending. The suction unit 3 and the second drive member 4 can also move as a whole in the second direction Y to approach or move away from the support platform 1 in the second direction Y.

[0051] In a specific application scenario, the suction unit 3 first sucks in and secures the strip-shaped part to be bent; then, by moving on the fifth slide rail 14, the suction unit 3 moves the part to a position opposite the carrier 1. By moving on the sixth slide rail 16, the part is brought close to the carrier 1 and finally the middle portion is placed on the carrier 1. The first pressure block 2 moves in the second direction Y and the vertical direction Z, pressing the part onto the carrier 1. The second driving member 4 drives the suction unit 3 to rotate 90°, and then the second pressure block 5 moves in the first direction X, pressing the bent part of the part onto the carrier 1. After staying for a predetermined time, the second pressure block 5 moves away, and the suction unit 3 drives the bent part away from the carrier 1 and moves to the next station on the fifth slide rail 14.

There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this specification, unless otherwise specified, "plurality" means two or more.

For values ​​less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples intended to be clearly stated, and it is to be understood that all possible combinations of the values ​​listed between the minimum and maximum values ​​are explicitly stated in this specification in a similar manner.

[0054] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. When used with a range, "about" or "approximately" applies to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the specified endpoints.
