[0042] To provide a clearer understanding of the embodiments of this disclosure, the embodiments of this disclosure will be described in detail below with reference to Figures 1 to 8.

[0043] As shown in Figures 1 to 7, this disclosure provides a bending device 1 for bending a workpiece 2. The bending device 1 includes a bending mechanism 11 and a laser cleaning mechanism 12. The bending mechanism 11 includes a first bending member 111 and a second bending member 112 spaced apart. A protrusion 1111 and a recess 1121 matching the protrusion 1111 are respectively provided on two surfaces of the first bending member 111 and the second bending member 112. The first bending member 111 and the second bending member 112 can move closer or further apart to achieve bending of the workpiece 2. The laser cleaning mechanism 12 includes a laser emitter 121, which is disposed on the side of the first bending member 111 away from the workpiece 2. The first bending member 111 has a first hollow portion 1112. And / or the laser emitter 121 is disposed on the side of the second bending member 112 away from the workpiece 2. The second bending member 112 has a second hollow portion.

[0044] The component to be bent 2 can be any part that needs to be bent and welded. For example, in some embodiments, the component to be bent 2 can be the tab in a battery. After bending, the tab and the cap can be tightly fitted. The laser cleaning mechanism 12 can clean the surface of the tab to ensure the welding quality of the tab and the cap.

[0045] On the two adjacent surfaces of the first bending member 111 and the second bending member 112, a protrusion 1111 and a recess 1121 are respectively provided. That is, the protrusion 1111 and the recess 1121 are respectively provided on the adjacent surfaces of the first bending member 111 and the second bending member, and the shape of the protrusion 1111 corresponds to the shape of the recess 1121 to ensure that the protrusion 1111 can be inserted into the recess 1121. Therefore, when the first bending member 111 and the second bending member 112 approach each other, the protrusion 1111 will be inserted into the recess 1121, thereby bending the member 2 to be bent between the first bending member 111 and the second bending member 112. It should be noted that the specific shape and number of the protrusion 1111 can be designed according to the bending requirements of the member 2 to be bent, and this embodiment does not limit this.

[0046] Specifically, before bending, the part 2 to be bent is placed between the first bending part 111 and the second bending part 112. During bending, the first bending part 111 and the second bending part 112 move closer to each other, so that when the protrusion 1111 on the first bending part 111 is inserted into the recess 1121, the part 2 to be bent is also pushed into the recess 1121, resulting in the bending area of ​​the part 2 to be bent being restricted between the protrusion 1111 and the recess 1121, thus realizing the bending of the part 2 to be bent.

[0047] In some embodiments, when the recess 1121 is away from the edge of the second bending member 112, the recess 1121 may be formed by the inward indentation of the surface of the second bending member 112 near the first bending member 111. In other embodiments, as shown in FIG2, when the recess 1121 is located at the edge of the second bending member 112, the recess 1121 may be formed by a notch at the edge of the second bending member 112.

[0048] The first bending member 111 and the second bending member 112 can move closer to or further away from each other. Specifically, in some embodiments, one of the first bending member 111 and the second bending member 112 can move relative to each other, thereby adjusting the relative position between the first bending member 111 and the second bending member 112; in other embodiments, both the first bending member 111 and the second bending member 112 can move relative to each other, thereby adjusting the relative position between the first bending member 111 and the second bending member 112. The adjustment of the relative position of the first bending member 111 and the second bending member 112 can be achieved by a guide rail slider mechanism or by a gear and rack mechanism, and this disclosure does not limit this.

[0049] Laser emitter 121 refers to a device that can emit lasers. The emitted laser can clean the surface of the part to be bent 2, removing electrolytes, dust and other dirt from the surface of the part to be bent 2, preventing defects such as incomplete welding in the subsequent welding process, and improving the welding quality.

[0050] In some embodiments, a laser emitter 121 is disposed on the side of the first bending member 111 away from the member 2 to be bent, and the first bending member 111 is provided with a first hollow portion 1112. By providing the first hollow portion 1112, the laser emitted by the laser emitter 121 can pass through the first bending member 111 and act on the surface of the member 2 to be bent near the first bending member 111, thereby performing laser cleaning on the surface. In other embodiments, the laser emitter 121 is disposed on the side of the second bending member 112 away from the member 2 to be bent, and the second bending member 112 is provided with a second hollow portion 1112. The laser emitter 121 can pass through the second bending member 112 and act on the surface of the workpiece 2 to be bent that is close to the second bending member 112 by setting the second hollow part, so as to perform laser cleaning on the surface. In some embodiments, the laser emitter 121 is simultaneously set on the side of the first bending member 111 away from the workpiece 2 and the side of the second bending member 112 away from the workpiece 2, and the first bending member 111 and the second bending member 112 are respectively provided with the first hollow part 1112 and the second hollow part, so as to achieve cleaning of the two surfaces of the workpiece 2 to be bent.

[0051] By setting up the bending mechanism 11, when the first bending member 111 and the second bending member 112 approach each other, the protrusion 1111 will enter the recess 1121, thereby bending the workpiece 2 to be bent, which is accommodated between the first bending member 111 and the second bending member 112. At the same time, the laser emitter 121 in the laser cleaning mechanism 12 can emit a laser to clean the welding area on the workpiece 2 to be bent, removing impurities such as electrolyte from the surface of the workpiece 2 to be bent, and ensuring the subsequent welding quality of the workpiece 2 to be bent. That is, the bending device 1 of this disclosure can simultaneously clean the workpiece 2 to be bent during the bending process, so that the bending and cleaning processes of the workpiece 2 to be bent can be performed at the same time, which can improve the production efficiency of the workpiece 2 to be bent.

[0052] As shown in Figures 1, 5 and 6, in some embodiments, the bending device 1 further includes a first frame 13, and the first bending member 111 is movably disposed on the first frame 13 along a first preset direction S1, the first preset direction S1 forming a certain angle with the horizontal direction X.

[0053] The first bending member 111 is movably disposed on the first frame 13 along the first preset direction S1. Specifically, the movable connection between the first bending member 111 and the first frame 13 can be achieved by a guide rail slider mechanism or by a gear and rack mechanism. This embodiment does not limit the scope of the invention.

[0054] The first preset direction S1 refers to the direction that forms a certain angle with the horizontal direction X, that is, the inclined direction. Specifically, the first preset direction S1 can be inclined upward or inclined downward. By setting the first preset direction S1 to the inclined direction, when the bending position of the part to be bent 2 is accommodated in the groove (that is, when the bending position of the part to be bent 2 along the horizontal direction is blocked by other parts), the first bending part 111 can avoid the blocking parts and successfully achieve the bending of the part to be bent 2.

[0055] By movably arranging the first bending member 111 along the first preset direction S1 in the first frame 13, the first bending member 111 can move along the first preset direction S1, thereby bringing the first bending member 111 and the second bending member 112 closer to each other to complete the bending of the part 2 to be bent.

[0056] As shown in Figures 3 to 5, in some embodiments, the protrusion direction of the protrusion 1111 is the first preset direction S1, and the concave direction of the recess 1121 is the first preset direction S1.

[0057] The protruding direction of the protrusion 1111 and the recessing direction of the concave part 1121 are both set to the first preset direction S1. When the first bending member 111 moves along the first preset direction S1, it can ensure that the protrusion 1111 smoothly enters the concave part 1121, avoid interference between the two, and ensure the bending quality of the bending device 1.

[0058] As shown in Figure 5, in some embodiments, a first guide rail 131 extending along a first preset direction S1 is provided on the first frame 13, and a first slider 113 is provided on the first bent member 111, the first slider 113 being slidably disposed on the first guide rail 131; or a first guide rail (not shown in the figure) extending along the first preset direction S1 is provided on the first bent member 111, and a first slider is provided on the first frame 13, the first slider being slidably disposed on the first guide rail. That is, one of the first guide rail 131 and the first slider 113 is disposed on the first frame 13, and the other is disposed on the first bent member 111, the first bent member 111 moving relative to the first frame 13 is achieved by the movement of the first slider 113 on the first guide rail 131.

[0059] As shown in Figures 1 and 7, in some embodiments, the bending device 1 further includes a second frame 14, the second bending member 112 is fixedly disposed on the second frame 14, and the recess 1121 and the protrusion 1111 are correspondingly disposed along the first preset direction S1.

[0060] The second bending member 112 is fixedly disposed on the second frame 14, meaning there is no relative movement between the second bending member 112 and the second frame 14. During bending, the second bending member 112 remains stationary, while the first bending member 111 moves along the first preset direction S1 and approaches the second bending member 112, thereby achieving the bending of the part 2 to be bent. Specifically, the fixed connection between the second bending member 112 and the second frame 14 can be a detachable connection method such as bolt connection or snap-fit, or a non-detachable connection method such as welding or bonding. This embodiment does not limit the connection in this respect.

[0061] The recess 1121 and the convex part 1111 are correspondingly arranged along the first preset direction S1, so as to ensure that when the first bending member 111 moves along the first preset direction S1, the convex part 1111 can smoothly enter the recess 1121, avoiding interference between the two and ensuring the bending quality of the bending device 1.

[0062] As shown in Figures 1 and 7, in some embodiments, the bending device 1 further includes a second frame 14, and the second bending member 112 is movably disposed on the second frame 14 along a second preset direction S2.

[0063] The second bending member 112 is movably disposed on the second frame 14 along the second preset direction S2. That is, during the bending process, both the first bending member 111 and the second bending member 112 can move, thereby increasing the relative movement speed between the two and thus accelerating the bending speed of the part 2 to be bent.

[0064] Specifically, the movable connection between the second bent member 112 and the second frame 14 can be achieved through a guide rail slider mechanism. For example, in some embodiments, the second frame 14 is provided with a second guide rail 141 extending along a second preset direction S2, and the second bent member 112 is provided with a second slider 114, which is slidably disposed on the second guide rail 141; or the second bent member 112 is provided with a second guide rail (not shown in the figure) extending along a second preset direction S2, and the second frame 14 is provided with a second slider, which is slidably disposed on the first guide rail. That is, one of the second guide rail 141 and the second slider 114 is disposed on the second frame 14, and the other is disposed on the second bent member 112, and the movement of the second bent member 112 relative to the second frame 14 is achieved by the movement of the second slider 114 on the second guide rail 141.

[0065] In some embodiments, the second preset direction S2 can be a horizontal direction, that is, when bending, the first bending member 111 moves in an inclined direction while the second bending member 112 moves in a horizontal direction, thereby changing the relative distance between them and realizing the bending of the part 2 to be bent. In other embodiments, the second preset direction S2 can also be an inclined direction at a certain angle to the horizontal direction, that is, when bending, both the first bending member 111 and the second bending member 112 move in an inclined direction to change the relative distance between them and realize the bending of the part 2 to be bent.

[0066] As shown in Figures 3, 4 and 7, in some embodiments, the second preset direction S2 forms a certain angle with the horizontal direction X, and the angle a1 between the first preset direction S1 and the horizontal direction X is equal to the angle a2 between the second preset direction S2 and the horizontal direction X.

[0067] The second preset direction S2 forms a certain angle with the horizontal direction X. That is, when bending, the second bending member 112 moves along the inclined direction to change the relative distance between the first bending member 111 and the second bending member 112, so as to realize the bending of the member 2 to be bent.

[0068] The angle a1 between the first preset direction S1 and the horizontal direction X and the angle a2 between the second preset direction S2 and the horizontal direction X are complementary angles. That is, when the first bending part 111 and the second bending part 112 move, they move along the two isosceles sides of the isosceles triangle, which facilitates the adjustment of the moving distance and orientation of the two parts, ensures the smooth cooperation of the convex part 1111 and the concave part 1121, and accurately realizes the bending of the part 2 to be bent.

[0069] As shown in Figures 1, 5 and 6, in some embodiments, the laser cleaning mechanism 12 includes a protective cover 122 covering the laser emitter 121, and the protective cover 122 has a through hole 1221 on the side near the part 2 to be bent.

[0070] The through hole 1221 can be circular or square, and this embodiment does not limit it.

[0071] By setting up a protective cover 122, the laser emitter 121 is enclosed inside the protective cover 122. When cleaning the part to be bent 2, impurities and other debris can be prevented from splashing onto the laser emitter 121, which would block the laser emitted by the laser emitter 121 and reduce its energy, thus reducing the cleaning effect of the part to be bent 2.

[0072] As shown in Figures 1 and 2, in some embodiments, the bending device 1 further includes a dust removal mechanism 15, which is disposed at the upper end of the bending mechanism 11, and the dust suction port 151 of the dust removal mechanism 15 is correspondingly disposed with the workpiece 2 to be bent.

[0073] When the laser cleaning mechanism 12 cleans the bent part 2, the generated smoke and other impurities will flow upward. Therefore, the dust removal mechanism 15 is set at the upper end of the bending mechanism 11 to facilitate the collection of smoke and other impurities and improve the dust removal effect.

[0074] The dust removal mechanism 15 has a suction port 151 that corresponds to the part 2 to be bent, which can ensure that the suction force generated by the dust removal mechanism 15 can be effectively applied to the part 2 to be bent to the maximum extent, thereby improving the dust removal effect of the part 2 to be bent.

[0075] By setting up a dust removal mechanism 15, impurities such as smoke can be removed during the laser cleaning process, preventing impurities from falling back onto the surface of the part to be bent 2 and improving the cleaning effect of the part to be bent 2.

[0076] As shown in Figure 8, in another aspect, this disclosure provides a welding device, which includes a bending device 1 and a welding device 3. The welding device 3 is disposed downstream of the bending device 1 and is used to weld the part 2 to be bent.

[0077] The welding device 3 is located downstream of the bending device 1. That is, during the production process, the part to be bent 2 first passes through the bending device 1, and after bending and cleaning in the bending device 1, it passes through the welding device 3, thereby improving the welding quality of the part to be bent 2 in the welding device 3.

[0078] Specifically, as shown in Figures 1 to 8, before bending, the part to be bent is placed between the first bending part 111 and the second bending part 112.

[0079] During bending, the first bending member 111 and the second bending member 112 move closer together, thereby pressing the part 2 to be bent 2 between the first bending member 111 and the second bending member 112, and the bending of the part 2 is achieved through the cooperation between the protrusion 1111 and the concave part 1121. At the same time, the laser emitter 121 of the laser cleaning mechanism 12 emits a laser. The laser passes through the through hole 1221 on the protective cover 122 and the hollow part on the bending mechanism 11 and acts on the part 2 to be bent, cleaning the part 2. During the cleaning process, the dust removal mechanism 15 is opened simultaneously or in advance to remove the smoke and dust generated during the cleaning process.

[0080] After bending is completed, the bent part 2 is welded on the welding device 3.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
