[0032] Please refer to Figure 1 and Figure 2The feeding and bending device provided by the embodiment comprises a bending mechanism 20 and a feeding mechanism 700. The bending mechanism 20 has a wire receiving groove 211 extending along a first direction X. The feeding mechanism 700 comprises a feeding support 710, a wire feeding mounting frame 720, a first wire feeding assembly 731, a second wire feeding assembly 732 and an alignment driving member 740. The first wire feeding assembly 731 and the second wire feeding assembly 732 are installed at intervals along a second direction Y on the wire feeding mounting frame 720. The wire feeding mounting frame 720 is slidingly installed on the feeding support 710 along the second direction Y. The alignment driving member 740 drives the wire feeding mounting frame 720 to make reciprocating linear motion along the second direction Y, so that the first wire feeding assembly 731 and the second wire feeding assembly 732 are aligned with the wire receiving groove 211 in turn. The first direction X, the second direction Y and a vertical direction Z are perpendicular to each other.

[0033] Therefore, the first wire feeding assembly 731 and the second wire feeding assembly 732 are used for feeding the bending mechanism 20. The alignment driving member 740 drives the wire feeding mounting frame 720 to make reciprocating linear motion along the second direction Y, so that the first wire feeding assembly 731 and the second wire feeding assembly 732 are aligned with the wire receiving groove 211 of the bending mechanism 20 in turn. When the first wire feeding assembly 731 feeds the wire receiving groove 211, the bending mechanism 20 starts the bending operation. The alignment driving member 740 can immediately drive the wire feeding mounting frame 720 to slide, so that the second wire feeding assembly 732 is aligned with the wire receiving groove 211 and completes the next feeding. When the second wire feeding assembly 732 completes the feeding, the first wire feeding assembly 731 is reset and ready, and can be switched to alignment again. The feeding action and the bending action almost overlap without gap, the linkage connection improves the efficiency, saves the cost and speeds up the production rhythm.

[0034] In some embodiments, in combination with Figure 2 and Figure 3 The feeding mechanism 700 further comprises a wire feeding driving member 750. The first wire feeding assembly 731 and the second wire feeding assembly 732 are slidingly installed on the wire feeding mounting frame 720 along the first direction X. The wire feeding driving member 750 drives the first wire feeding assembly 731 and the second wire feeding assembly 732 to slide along the first direction X, so that the first wire feeding assembly 731 and the second wire feeding assembly 732 are aligned with the wire receiving groove 211 in turn. When the first wire feeding assembly 731 feeds the wire, the wire feeding driving member 750 drives the first wire feeding assembly 731 to approach the wire receiving groove 211, so as to reduce the interval between the first wire feeding assembly 731 and the wire receiving groove 211 along the first direction X. The wire feeding stability is improved, and the slight deviation of the flat wire 10 caused by gravity and inertia is avoided.

[0035] Optionally, when the first wire feeding assembly 731 is fed, the wire feeding driving member 750 drives the first wire feeding assembly 731 away from the wire receiving groove 211, so as to facilitate the first wire feeding assembly 731 to receive the new flat wire 10 without interfering with the bending mechanism 20.

[0036] In some embodiments, in combination with Figure 3 and Figure 4 , the first wire feeding assembly 731 and the second wire feeding assembly 732 are provided with a transmission rack 733 on the side facing each other, the number of the wire feeding driving member 750 is one, the wire feeding driving member 750 is located between the first wire feeding assembly 731 and the second wire feeding assembly 732 in the second direction Y, the wire feeding driving member 750 is connected with a transmission gear 751, and the transmission gear 751 is meshed with the two transmission racks 733 on the opposite sides in the second direction Y. Based on this, one wire feeding driving member 750 drives the two transmission racks 733 to slide, and the sliding directions of the first wire feeding assembly 731 and the second wire feeding assembly 732 are opposite, which exactly meets the working process that one of them is close to the wire receiving groove 211 for feeding, and the other is away from the wire receiving groove 211 for receiving the new flat wire 10. The movement of the two has mechanical rigidity synchronization, and keeps reliable production rhythm. In addition, the transmission gear 751 is directly meshed with the transmission rack 733, the wire feeding driving member 750 is located between the first wire feeding assembly 731 and the second wire feeding assembly 732 in the second direction Y, without the need for additional intermediate components such as transmission connecting rods and belts, so that the space layout of the feeding mechanism 700 is more compact, and the transmission distance is shortened, which is beneficial to improve the production rhythm.

[0037] Specifically, the first wire feeding assembly 731 and the second wire feeding assembly 732 are both slidingly installed on the wire feeding mounting frame 720 and provided with a pair of first sliding rails 722 spaced apart in the second direction Y, the length direction of the first sliding rail 722 is consistent with the first direction X, and the first wire feeding assembly 731 and the second wire feeding assembly 732 are both slidingly installed on the first sliding rail 722. Optionally, the transmission gear 751 is located between the pair of first sliding rails 722.

[0038] In some embodiments, in combination with Figure 3 and Figure 4 , the first wire feeding assembly 731, the second wire feeding assembly 732 and the transmission gear 751 are located on the top of the wire feeding mounting frame 720, the wire feeding driving member 750 is installed on the bottom of the wire feeding mounting frame 720, the output end of the wire feeding driving member 750 is movably passed through the wire feeding mounting frame 720 and connected with the transmission gear 751, so as to realize the stagger of the three in the vertical direction Z, avoid motion interference, without the need to expand the size of the wire feeding mounting frame 720 in the horizontal plane, so that the whole feeding mechanism 700 is more compact, the driving distance of the wire feeding driving member 750 is shortened, and it is beneficial to improve the production rhythm.

[0039] In some embodiments, in combination with Figure 2 andFigure 4 The feeding support 710 has a sliding groove 711 extending through in the vertical direction Z, the sliding groove 711 extending along the second direction Y, the wire feeding driving member 750 movably arranged in the sliding groove 711, avoiding interference between the wire feeding driving member 750 and the feeding support 710, and the feeding support 710 and the wire feeding driving member 750 arranged in the horizontal plane overlappingly, so that the feeding mechanism 700 is more compact in the whole, the structural size and the conveying distance are shortened, and the production rhythm is improved.

[0040] In some embodiments, in combination with Figure 3 and Figure 4 The feeding support 710 is provided with a pair of sliding buffers 712 located on both sides of the sliding groove 711 in the second direction Y. The sliding buffer 712 (usually a hydraulic buffer, a polyurethane buffer) gradually absorbs impact energy through damping action or elastic deformation, so that the wire feeding mounting frame 720 smoothly transits from the motion state to the stop state.

[0041] In some embodiments, in combination with Figure 3 and Figure 4 The feeding support 710 is provided with a pair of support sliding rails 713 located on both sides of the sliding groove 711 in the first direction X, and the wire feeding mounting frame 720 is slidably mounted on the support sliding rail 713. The pair of support sliding rails 713 can uniformly disperse the total load of the wire feeding mounting frame 720, and improve the sliding precision and smoothness of the wire feeding mounting frame 720.

[0042] In some embodiments, in combination with Figure 3 and Figure 4 At least one of the first wire feeding assembly 731 and the second wire feeding assembly 732 includes a wire feeding support 734, a wire feeding plate 735 and a wire feeding clamp 736, the wire feeding support 734 is mounted on the wire feeding mounting frame 720, the wire feeding plate 735 is mounted on the top of the wire feeding support 734, the wire feeding plate 735 has a clamping opening 737 extending through in the vertical direction Z, and the wire feeding clamp 736 is mounted on the wire feeding support 734 and exposed at the clamping opening 737. The wire feeding clamp 736 clamps the flat wire 10 through the clamping opening 737, can adapt to feeding of various specifications of the flat wire 10, avoids that the flat wire 10 is prone to horizontal deviation or vertical movement without constraint in the feeding process, and causes slot deviation.

[0043] In some embodiments, in combination with Figure 3 and Figure 4 The wire feeding clamp 736 is located at one end of the wire feeding support 734 close to the bending mechanism 20, so as to ensure that the position of the end part of the flat wire 10 close to the bending mechanism 20 is stable and accurate, and the slot is smooth.

[0044] In some embodiments, in combination with Figure 3 and Figure 4The top of the wire feeding plate 735 is provided with a plurality of pairs of limiting blocks 738 distributed at intervals along the first direction X. The interval between each pair of limiting blocks 738 limits a wire feeding groove 739, and the wire feeding groove 739 passes through the clamping opening 737. The wire feeding groove 739 extends along the first direction X and passes through the clamping opening 737. After the wire is placed in the wire feeding groove 739, each pair of limiting blocks 738 will form a transverse constraint (left and right side limiting) to the wire, achieving preliminary positioning. Even if there is slight swinging during feeding, the wire will be blocked by the limiting blocks 738 and cannot deviate from the channel.

[0045] In some embodiments, in combination with Figure 3 and Figure 4 The alignment driving member 740 is installed at the end of the feeding support 710 away from the bending mechanism 20. The alignment driving member 740 is kept at the maximum distance from the bending mechanism 20 (the front end working area) to avoid interference between the two. The alignment driving member 740 does not occupy the front end space of the wire feeding mounting rack 720, which is beneficial to the first wire feeding assembly 731 and the second wire feeding assembly 732 being closer to the bending mechanism 20, facilitating the entry of the flat wire 10 into the groove. Specifically, the alignment driving member 740 is located below the wire feeding mounting rack 720, so that the first wire feeding assembly 731 and the second wire feeding assembly 732 above the wire feeding mounting rack 720 can slide in the first direction X to above the alignment driving member 740 without collision, that is, the stroke of the first wire feeding assembly 731 and the second wire feeding assembly 732 can be greater than the size of the wire feeding mounting rack 720, which is beneficial to the miniaturization design of the wire feeding mounting rack 720. Specifically, the wire feeding mounting rack 720 is connected with a downwardly extending supporting lug 721, and the output end of the alignment driving member 740 is connected with the supporting lug 721.

[0046] Please refer to Figure 1 The bending mechanism 20 and the feeding mechanism 700 are both installed on the rack 100.

[0047] In some embodiments, please refer to Figure 5 The bending mechanism 20 includes a linear pushing mechanism 200 and a rotary bending mechanism 300. In combination with Figure 6 and Figure 7 The linear pushing mechanism 200 includes a feeding plate 210, a pushing assembly 220, and a clamping assembly 230. The feeding plate 210 is installed on the rack 100, and the feeding plate 210 has wire receiving grooves 211 and wire clamping grooves 212 (see Figure 8). The wire clamping groove 212 is located on the extension line of the wire receiving groove 211. The thickness direction of the feeding plate 210 is consistent with the vertical direction. The wire receiving groove 211 does not penetrate the feeding plate 210 in the vertical direction, and the wire clamping groove 212 penetrates the feeding plate 210 in the vertical direction. The pushing assembly 220 pushes the flat wire 10 to slide from the wire receiving groove 211 to the wire clamping groove 212 in the first direction X, and the clamping assembly 230 clamps the flat wire 10 up and down to move in the penetrating wire clamping groove 212. In other words, the wire receiving groove 211 provides initial guidance for the flat wire 10, and the pushing assembly 220 only needs to push in the first direction X without additional correction; the wire clamping groove 212 cooperates with the up and down clamping of the clamping assembly 230 to firmly fix the flat wire 10 in the wire clamping groove 212, avoiding positioning deviation caused by left and right deviation and upward and downward warping during conveying.

[0048] In combination with Figure 5 and Figure 7 , the rotary bending mechanism 300 includes a rotary driving member 310, a pressing driving member 320, and a first bending block 330. The first bending block 330 has a bending groove 331 that is in butt joint with the end of the wire clamping groove 212, and the bending groove 331 penetrates the first bending block 330 in the first direction X. The output end of the pressing driving member 320 is connected with a pressing block 321 that presses the flat wire 10 on the bending groove 331, and the output end of the rotary driving member 310 is connected with a second bending block 311 that is located outside the first bending block 330. The rotary driving member 310 drives the second bending block 311 to rotate to push the flat wire 10 exposed to the bending groove 331 in the first direction X to bend. Each time the flat wire 10 is bent, the positioning of the flat wire 10 in the vertical direction deviates, and the bending size of the final product is out of tolerance. In other words, the middle and rear sections of the flat wire 10 in the first direction X are simultaneously positioned left and right by the bending groove 331 and the wire clamping groove 212, respectively, and are simultaneously clamped up and down by the pressing block 321 and the clamping assembly 230, respectively, to avoid the position of the front section of the flat wire 10 deviating before bending, resulting in inaccurate bending direction and angle, and further causing the bending structure to not meet the requirements, and avoiding the middle and rear sections of the flat wire 10 from warping due to stress during bending, resulting in structural deformation.

[0049] Based on this, the pushing assembly 220 pushes the flat wire 10 in the wire receiving groove 211 to slide in the first direction X into the wire clamping groove 212, the clamping assembly 230 clamps the flat wire 10 in the wire clamping groove 212 to move in the first direction X to the bending groove 331 of the first bending block 330, the downward driving member 320 drives the downward block 321 to press and fix the flat wire 10 in the bending groove 331, and the rotary driving member 310 drives the second bending block 311 to rotate, the second bending block 311 rotates to touch the flat wire 10 exposed in the first direction X from the bending groove 331, and pushes the exposed flat wire 10 to bend around the port of the bending groove 331. Wherein, when the rotary bending mechanism 300 bends the flat wire 10, the clamping assembly 230 clamps the flat wire 10 up and down, which ensures that the rear end of the flat wire 10 does not deviate and does not deform during the front end bending deformation of the flat wire 10, so that the bent flat wire 10 meets the corresponding structure requirements.

[0050] In addition, when the clamping assembly 230 delivers the current flat wire 10 to the bending position, the pushing assembly 220 synchronously pushes the next flat wire 10 to the wire clamping groove 212, the first wire feeding assembly 731 synchronously provides the flat wire 10 to the wire receiving groove 211, and the second wire feeding assembly 732 synchronously bears the new flat wire 10 and prepares to feed the wire receiving groove 211, realizing continuous connection and not having to wait until the bending is completed before the bending mechanism 20 feeds, thereby improving the production rhythm.

[0051] In some embodiments, in combination with Figure 5 , Figure 6 and Figure 10 , the pushing assembly 220 includes a first linear driving member 221, a first lifting driving member 222, and a pushing member 223. The first linear driving member 221 is installed on the rack 100, the first linear driving member 221 drives the first lifting driving member 222 to slide in the first direction X, and the first lifting driving member 222 drives the pushing member 223 to move up and down. Before pushing, the first lifting driving member 222 can first drive the pushing member 223 to descend, so that the pushing member 223 adjusts the height to ensure that it can accurately abut against the rear end of the flat wire 10. After the alignment is completed, the first linear driving member 221 drives the whole to slide in the first direction X, realizing stable pushing. After the pushing member 223 pushes the flat wire 10 from the wire receiving groove 211 to the wire clamping groove 212, the first linear driving member 221 and the first lifting driving member 222 are reset to prepare for the pushing of the next flat wire 10.

[0052] In one embodiment, in combination with Figure 6 and Figure 9 , the pushing member 223 has a first protruding block 2234 which can be embedded in the wire receiving groove 211. The first protruding block 2234 is used to abut against the end of the flat wire 10 away from the rotary bending mechanism 300, and abutting against the end during pushing can ensure that the flat wire 10 translates and slides in the first direction X, and the problem of misalignment of the front and rear sections of the flat wire 10 during pushing can be avoided.

[0053] In one embodiment, in combination with Figure 6 and Figure 9 The pushing member 223 comprises a connecting frame 2231 and a pushing plate 2232, one end of the connecting frame 2231 is installed on the first lifting driving member 222, the other end of the connecting frame 2231 is connected to the pushing plate 2232, and the lower end of the pushing plate 2232 protrudes below the connecting frame 2231. The connecting frame 2231 is hollow, which reduces the overall weight of the pushing member 223 and reduces the load and energy consumption of the first linear driving member 221 and the first lifting driving member 222.

[0054] In one embodiment, in combination with Figure 9 The bottom of the pushing plate 2232 has a first abutting plane 2233, which is perpendicular to the vertical direction. The cross section of the flat wire 10 (especially the thin flat wire 10) is flat, and the first abutting plane 2233 can form a surface contact with the top surface of the flat wire 10, which limits the movement of the flat wire 10 in the vertical direction, ensures that the flat wire 10 accurately slides into the wire clamping groove 212 from the wire receiving groove 211, and reduces positioning errors during conveying.

[0055] In one embodiment, in combination with Figure 9 The first protrusion 2234 is protrudingly arranged at the end of the first abutting plane 2233 away from the rotary bending mechanism 300, and the side of the first protrusion 2234 close to the rotary bending mechanism 300 has a second abutting plane 2236. The second abutting plane 2236 forms a plane abutment with the end of the flat wire 10, and the pushing force can be uniformly dispersed to the abutting area, the surface contact can provide more stable lateral restraint, completely avoid slipping or mispositioning, and ensure that the flat wire 10 and the pushing member 223 move completely synchronously.

[0056] In one embodiment, in combination with Figure 9 The bottom of the first protrusion 2234 has a third abutting plane 2235, which can directly abut the groove bottom plane of the wire receiving groove 211, firmly limits the displacement of the flat wire 10 in the vertical direction, completely avoids its upward tilting or up-down movement, and ensures that the flat wire 10 always abuts the groove bottom to stably slide.

[0057] In some embodiments, in combination with Figure 5 and Figure 6The first lifting driving member 222 comprises a first driving body 2221 and a first lifting block 2222. The first driving body 2221 has a first sliding groove 2223 extending in the vertical direction. The first lifting block 2222 is vertically slidingly installed in the first sliding groove 2223. One side of the first lifting block 2222 in the second direction Y is connected with the pushing member 223. The other side of the first lifting block 2222 in the second direction Y abuts against the first driving body 2221 through a first elastic member 2224. If the first lifting block 2222 and the first driving body 2221 are rigidly connected, the contact between the first lifting block 2222 and the first driving body 2221 when starting and stopping will form a rigid collision, and the instantaneous impact force can cause the pushing member 223 to knock against the notch of the wire receiving groove 211 and the end of the flat wire 10. The first elastic member 2224 can form a flexible buffer between the first lifting block 2222 and the first driving body 2221. At the same time, the first elastic member 2224 can continuously apply a pre-tightening force to the first lifting block 2222 towards the side of the pushing member 223. When the size of the flat wire 10 fluctuates, the first elastic member 2224 can be slightly compressed / expanded, driving the first lifting block 2222 to make a slight displacement in the second direction Y, so that the pushing member 223 can always closely fit the side of the flat wire 10.

[0058] Specifically, in combination with Figure 6 The first sliding groove 2223 comprises a first wide groove and a first narrow groove in the second direction Y. The first wide groove is farther away from the wire receiving groove 211 than the first narrow groove. The size of the first wide groove in the first direction X is greater than the size of the first narrow groove in the first direction X. That is, the projection of the first sliding groove 2223 in the vertical direction is T-shaped. The shape of the first lifting block 2222 is matched with the first sliding groove 2223, so that the first lifting block 2222 cannot be separated from the first sliding groove 2223 in the second direction Y. The opposite sides of the T-shaped first lifting block 2222 and the first wide groove form close contact, thereby enhancing the lifting sliding support area.

[0059] Specifically, the first sliding groove 2223 is provided with a first limiting structure to limit the lifting range of the first lifting block 2222 in the vertical direction. The first limiting structure can be a limiting step or a limiting pin in the first sliding groove 2223.

[0060] In some embodiments, in combination with Figure 6 , Figure 10 and Figure 11The bending mechanism 20 further comprises a first material guiding driving member 411 mounted on the feeding plate 210, and the output end of the first material guiding driving member 411 is connected with a first material guiding plate 412, the thickness direction of the first material guiding plate 412 is consistent with the second direction Y, and the first material guiding plate 412 is located on the side of the wire receiving groove 211 away from the main body part of the material pushing assembly 220. The first material guiding driving member 411 drives the first material guiding plate 412 to move along the second direction Y, so as to form a limit on one side of the flat wire 10 in the second direction Y in the wire receiving groove 211. When the flat wire 10 falls outside the wire receiving groove 211 during feeding, the first material guiding plate 412 pushes the flat wire 10 to fall into the wire receiving groove 211 along the second direction Y, so as to facilitate the operation of the straight-line material pushing mechanism 200. When the width of the flat wire 10 is smaller than the width of the wire receiving groove 211, a transverse gap will be formed in the groove, and the flat wire 10 will be easily offset to one side during pushing due to uneven force, so as to cause the pushing track to deviate from the preset path, affect the position accuracy of the subsequent entry into the wire clamping groove 212, and if there is a transverse inclination of the flat wire 10 in the wire receiving groove 211, the frictional resistance will be unevenly distributed, which will cause the risk of jamming and local deformation. The first material guiding driving member 411 (such as a pneumatic cylinder or an electric push rod) drives the first material guiding plate 412 to move close to the flat wire 10 until the first material guiding plate 412 is attached to one side of the flat wire 10 in the second direction Y, so as to press the flat wire 10 on the groove wall of the wire receiving groove 211 in the second direction Y, and completely eliminate the risk of transverse offset.

[0061] In one embodiment, in combination with Figure 8 、 Figure 10 and Figure 11 , the feeding plate 210 has a first sliding hole 213 extending along the second direction Y, the first material guiding driving member 411 is mounted on the bottom of the feeding plate 210, so as to prevent spatial interference with the material pushing member 223 and the material clamping assembly 230, fully utilize the installation space of the feeding plate 210 in the vertical direction, not occupy the installation space of the feeding plate 210 in the first direction X and the second direction Y, and facilitate reduction of the size of the feeding plate 210 in the first direction X and the second direction Y. The bottom of the material pushing plate 2232 is connected with the output end of the first material guiding driving member 411, and the top of the material pushing plate 2232 is exposed to the feeding plate 210 through the first sliding hole 213.

[0062] In one of the embodiments, the pushing plate 2232 comprises a wide plate and a narrow plate, the wide plate has a size in the first direction X larger than that of the narrow plate, the narrow plate is slidingly arranged in the first sliding hole 213 and connected with the output end of the first material guiding driving member 411, and the wide plate is exposed to the feeding plate 210 and has a size in the first direction X larger than that of the first sliding hole 213, so that the wide plate is supported by the top surface of the feeding plate 210, thereby improving the stability of the pushing plate 2232, the large size of the wide plate can form a large area of adhesion with the side surface of the flat wire 10, thereby avoiding local stress concentration caused by too small contact area and more stably restricting the position of the flat wire 10 in the second direction Y, and reducing the lateral shaking in the pushing process.

[0063] In one of the embodiments, the size of the wide plate in the first direction X is 2-5 times of that of the narrow plate in the first direction X, so as to ensure that there is enough adhesion area between the wide plate and the flat wire 10, and avoid the cantilever end shaking in the sliding process due to too long size.

[0064] In one of the embodiments, in combination with Figure 6 and Figure 11 , the number of the pushing plates 2232 is two, both of the pushing plates 2232 are connected to the output end of the first material guiding driving member 411 and have equal distance from the output end of the first material guiding driving member 411, so that the load of the first material guiding driving member 411 is uniform, a “symmetrical force” is formed, the eccentric moment (the reaction force of the two contact points has equal size and opposite direction) is offset, the output end of the first material guiding driving member 411 only bears axial force, and the internal wear is greatly reduced. The pushing force applied by the first material guiding driving member 411 can be uniformly transmitted to the flat wire 10 through the two pushing plates 2232, the limiting area is further increased, the force of the flat wire 10 in the second direction Y is symmetrical and has no eccentric moment.

[0065] Specifically, the feeding plate 210 has a mounting position 216 located at the middle of the two first sliding holes 213, and the first material guiding driving member 411 is mounted on the mounting position 216.

[0066] In one of the embodiments, the output end of the first material guiding driving member 411 is further connected with a first buffer 413, such as a hydraulic buffer, a polyurethane buffer block or a spring buffer. The first buffer 413 is arranged towards the second direction Y and is used to limit and abut against the rack 100, so as to avoid the rigid collision between the first material guiding driving member 411 and the rack 100 and avoid the excessive forward stroke of the output end of the first material guiding driving member 411.

[0067] In one of the embodiments, in combination with Figure 6 and Figure 11The bending mechanism 20 further comprises a feeding driving element 421 installed on the feeding plate 210, and an output end of the feeding driving element 421 is connected with a feeding plate 422, the feeding plate 422 is located on a side of the wire receiving groove 211 away from the wire clamping groove 212, and the feeding driving element 421 drives the feeding plate 422 to move along the first direction X to push the flat wire 10 exposed to the wire receiving groove 211 into the wire receiving groove 211. When the flat wire 10 is fed, the end portion may be exposed to the wire receiving groove 211, the pushing element 223 is limited by the sliding stroke of the first linear driving element 221, and it is difficult to abut against the end portion of the flat wire 10, and even if the stroke is sufficient, since the pushing element 223 needs to be embedded in the wire receiving groove 211, and among the abutting areas, it is difficult to align the end portion of the flat wire 10 suspended outside the wire receiving groove 211. The feeding plate 422 can longitudinally sweep the flat wire 10 onto the feeding plate 210 under the pushing of the feeding driving element 421. If it falls outside the wire receiving groove 211, it is pushed into the wire receiving groove 211 through the first guide plate 412.

[0068] In one of the embodiments, the feeding driving element 421 is installed on the bottom of the feeding plate 210, fully utilizing the vertical installation space of the feeding plate 210, the thickness direction of the feeding plate 422 is consistent with the first direction X, and the top of the feeding plate 422 is higher than the groove of the wire receiving groove 211.

[0069] In one of the embodiments, the bottom of the feeding plate 210 is further connected with a second buffer 423, such as a hydraulic buffer, a polyurethane buffer block, or a spring buffer. The second buffer 423 is arranged towards the second direction Y, and the second buffer 423 is used to limit the abutting of the feeding plate 422, to avoid the rigid collision of the feeding plate 422 with the rack 100, and to limit the movement range of the feeding plate 422.

[0070] In some embodiments, in combination with Figure 5 and Figure 14 The clamping assembly 230 comprises a second linear driving element 231, a second lifting driving element 232, and two clamping elements 233 spaced apart in the up-down direction, the second linear driving element 231 is installed on the rack 100, the second linear driving element 231 drives the second lifting driving element 232 to slide along the first direction X, the clamping element 233 has a clamping plate capable of being embedded in the wire clamping groove 212, and the second lifting driving element 232 drives the two clamping elements 233 to perform lifting movement, so that the two clamping plates are folded or separated from each other in the vertical direction. The double clamping plates simultaneously apply clamping force from the upper and lower sides, can firmly fix the flat wire 10 at a preset height of the wire clamping groove 212, and accurately align the bending groove 331 of the rotary bending mechanism 300, to avoid the up-down movement, position deviation, and bending error caused by the transfer acceleration or the bending reaction force, and can be adapted to flat wires 10 of different thicknesses.

[0071] In one of the embodiments, in combination with Figure 14The second lifting driving member 232 comprises a second driving body 234 and two second lifting blocks 235. The second driving body 234 has a second sliding groove 236 extending in the vertical direction. The second lifting blocks 235 are vertically slidingly installed in the second sliding groove 236. One side of the second lifting blocks 235 in the second direction Y is connected with the clamping member 233. The other side of the second lifting blocks 235 in the second direction Y abuts against the second driving body 234 through a second elastic member 237. If the second lifting blocks 235 are rigidly connected with the second driving body 234, the contact between the second lifting blocks 235 and the second driving body 234 when starting and stopping will form a rigid collision, and the instantaneous impact force can cause the pushing member 223 to knock against the upper and lower notches of the wire clamping groove 212 and the end of the flat wire 10. The second elastic member 237 can form a flexible buffer between the second lifting blocks 235 and the second driving body 234. Meanwhile, the second lifting blocks 235 are cantilevered installed on the second driving body 234. The second elastic member 237 continuously applies a pre-tightening force to the second lifting blocks 235 towards the side of the wire clamping groove 212, so as to ensure that the end of the second lifting blocks 235 remains tensioned during the lifting process without deflection deformation, thereby improving the clamping force and clamping height stability of the flat wire 10.

[0072] Specifically, the second sliding groove 236 comprises a second wide groove and a second narrow groove in the second direction Y. The second wide groove is farther away from the wire clamping groove 212 than the second narrow groove. The size of the second wide groove in the first direction X is greater than the size of the second narrow groove in the first direction X. That is, the projection of the second sliding groove 236 in the vertical direction is T-shaped. The shape of the second lifting blocks 235 is adapted to the second sliding groove 236, so that the second lifting blocks 235 cannot be separated from the second sliding groove 236 in the second direction Y. The opposite sides of the T-shaped second lifting blocks 235 and the second wide groove form a close contact, thereby enhancing the lifting sliding support area and strictly limiting the posture deviation of the second lifting blocks 235.

[0073] The second sliding groove 236 is provided with a second limiting structure to limit the lifting range of the second lifting blocks 235 in the vertical direction. The second limiting structure can be a limiting step or a limiting pin in the second sliding groove 236.

[0074] In one embodiment, the second lifting driving member 232 is connected with the second driving body 234 through a second elastic member 237. Figure 5 、 Figure 12 and Figure 13The bending mechanism 20 further comprises at least one pair of positioning assemblies 500, each pair of positioning assemblies 500 is located on opposite sides of the wire clamping groove 212 in the second direction Y, the positioning assembly 500 comprises a positioning block 510, a sliding block 520, a rotating block 530 and a third elastic member 540, the positioning block 510 is fixedly installed on the feeding plate 210, the sliding block 520 is slidably installed on the feeding plate 210 and located on one side of the positioning block 510 close to the wire clamping groove 212, the rotating block 530 is rotatably installed on the sliding block 520, and the third elastic member 540 is compressed between the positioning block 510 and the sliding block 520. When the flat wire 10 passes through a pair of positioning assemblies 500, the flat wire 10 is in elastic contact and rolling contact with the rotating block 530 in the second direction Y, the elastic contact can adaptively limit the flat wire 10 of different specifications and sizes, the rolling contact reduces friction, protects the surface of the flat wire 10 and improves the smoothness of lifting and transferring. Each pair of positioning assemblies 500 symmetrically restricts the flat wire 10, offsets the bending stress of the flat wire 10 itself, forces the flat wire 10 to maintain a straight posture, avoids twisting or lateral bending, and meets the requirements of the bending structure.

[0075] Specifically, the rotating block 530 has a cylindrical surface for rolling contact with the flat wire 10. The generatrix of the cylindrical surface is parallel to and fits the side surface plane of the flat wire 10, which is stable in contact area and provides stable support force, and the "line contact" between the cylindrical surface and the flat wire 10 can greatly disperse the contact stress compared with point / edge surface contact.

[0076] In one embodiment, in combination with Figure 12 and Figure 13 , every two pairs of positioning assemblies 500 are arranged adjacent to each other in the first direction X, and the compression directions of the four third elastic members 540 of the two pairs of positioning assemblies 500 intersect at the same point in the wire clamping groove 212. Referring to Figure 12 , the compression directions of the four third elastic members 540 are F1, F2, F3 and F4, which converge at a point, i.e., acting on the same position of the flat wire 10 located in the wire clamping groove 212, which can form a concentrated and balanced force on the flat wire 10, making the position of the flat wire 10 in the wire clamping groove 212 more stable, effectively reducing the shaking and deviation of the flat wire 10 during the transferring process, and ensuring that the flat wire 10 can accurately pass through the bending mechanism 20, improving the bending precision and quality. Specifically, the elastic force directions of the two pairs of positioning assemblies 500 converge at a point, rather than forming a torque by being spaced apart, so that the flat wire 10 is mainly under normal pressure, the natural frequency of the flat wire 10 is controlled, which is beneficial to reduce the vibration of the flat wire 10 caused by the bending reaction force, and improve the position stability of the flat wire 10. It can be understood that in other embodiments, the compression direction of the third elastic member 540 is the second direction Y, and the compression direction of the third elastic member 540 of each pair of positioning assemblies 500 is directly opposite.

[0077] Optionally, the third elastic member 540 is a spring, an air damper or a rubber strip.

[0078] Specifically, in combination with Figure 13 , the feeding plate 210 has a third sliding groove 214, and the sliding block 520 is slidingly installed in the third sliding groove 214. The third sliding groove 214 guides and restricts the sliding direction of the sliding block 520, so as to avoid dislocation of the sliding block 520. Optionally, the length direction of the third sliding groove 214 is consistent with the compression direction of the third elastic member 540.

[0079] Specifically, in combination with Figure 13 , the sliding block 520 has a first mounting hole 521, and the end of the third elastic member 540 is embedded in the first mounting hole 521. In this way, the third elastic member 540 is prevented from being offset, falling off or unevenly stressed during compression / resetting. If the third elastic member 540 is not restricted by the first mounting hole 521, the third elastic member 540 will move radially, which will be transmitted to the rotating block 530 through the sliding block 520, and will cause the sliding block 520 to slightly swing laterally. The swing will make the cylindrical surface of the rotating block 530 no longer parallel to the side surface of the flat wire 10, and form an inclined contact.

[0080] Specifically, in combination with Figure 13 , the positioning block 510 has a second mounting hole, and the end of the third elastic member 540 is embedded in the second mounting hole. The second mounting hole and the first mounting hole 521 of the sliding block 520 form a two-end positioning structure of the third elastic member 540. Optionally, the second mounting hole and the first mounting hole 521 are coaxially arranged, and the third elastic member 540 is forced to be limited in the coaxial hole, so that the axis is always consistent with the stress direction, no matter compression or resetting.

[0081] Specifically, in combination with Figure 13 , the sliding block 520 has a third mounting hole 522 penetrating in the vertical direction, and one end of the rotating block 530 is rotatably penetrated through the third mounting hole 522. The rotating shaft of the rotating block 530 is forced to be restricted on the axis of the third mounting hole 522, so as to ensure that the rolling direction is always consistent with the conveying direction (the first direction X) of the flat wire 10, and there is no lateral force interference.

[0082] Optionally, the third sliding groove 214 is provided with a fourth sliding groove 215 penetrating through the bottom of the third sliding groove 214, and the bottom end of the rotating block 530 is arranged in the fourth sliding groove 215 to form a clearance fit. If only the third mounting hole 522 is used for constraint, the rotating block 530 may slightly move due to vibration or impact force, and if the movement is in the first direction X, the contact point of the rotating block 530 with the flat wire 10 will be offset forward and backward, which may cause the flat wire 10 to be stuck or deviate from the track during conveying. The fourth sliding groove 215 limits the movement of the rotating block 530 in the first direction X. At the same time, the fourth sliding groove 215 can support the rotation of the rotating block 530, and the force on the wall of the third mounting hole 522 above is balanced vertically, which greatly reduces the bending moment of the rotating block 530, the force on the rotating block 530 is more uniform, and the problem of local stress concentration is alleviated.

[0083] Optionally, the length of the fourth sliding groove 215 is less than the length of the third sliding groove 214. Optionally, the length directions of the third sliding groove 214 and the fourth sliding groove 215 are consistent.

[0084] In some embodiments, in combination with Figure 5 、 Figure 7 and Figure 14 , the bending mechanism 20 comprises an adapter plate 610 provided with an adapter groove 611 penetrating through the adapter plate 610 in the vertical direction. The adapter groove 611 can penetrate through the adapter plate 610 in the first direction X away from one end of the wire receiving groove 211. The adapter groove 611 is located directly above the bending groove 331, the pressing driving member 320 is installed on the top of the adapter plate 610, and the first bending block 330 is installed on the bottom of the adapter plate 610. The pressing driving member 320 and the first bending block 330 are respectively located on both sides of the adapter plate 610, and the adapter groove 611 can guide the pressing block 321 to be aligned with the bending groove 331, thereby improving the pressing accuracy and positioning accuracy of the pressing block 321 on the flat wire 10.

[0085] In one embodiment, the second bending block 311 is located outside the first bending block 330.

[0086] In one embodiment, the output end of the rotating driving member 310 is connected with a third bending block 312, the third bending block 312 is provided with a receiving hole 313 for accommodating the first bending block 330, and the receiving hole 313, the first bending block 330 and the output end of the rotating driving member 310 are coaxially arranged. If the center of the first bending block 330 deviates from the rotation center of the third bending block 312, the flat wire 10 is eccentrically clamped, and the flat wire 10 is easily skewed to one side during bending (for example, the flat wire 10 should be bent by 90°, but actually presents a "twisted shape").

[0087] In one embodiment, the second bending block 311 is installed on the top of the third bending block 312, and the second bending block 311 is located outside the receiving hole 313, so as to bend and form the flat wire 10 exposed outside the receiving hole 313.

[0088] In one embodiment, the second bending block 311 is detachably mounted on the top of the third bending block 312, and the second bending block 311 has a cylindrical bending side. The radius of the cylindrical surface can be directly designed as the required standard bending radius R of the flat wire 10. When bending, the inner side of the flat wire 10 directly fits the cylindrical surface to form, and the R value is directly determined by the cylindrical surface, without relying on the cooperation of multiple parts, and completely matches the high precision requirement. The contact between the cylindrical surface and the flat wire 10 is arc surface contact, and the contact area is 3-5 times larger than the plane, which can effectively disperse the bending pressure. The arc contact of the cylindrical surface expands the deformation area of the flat wire 10 from the line-plane contact at the beginning of bending to a continuous circular arc segment, and the stress can be uniformly transmitted along the circular arc direction, avoiding excessive local stress. Uniform stress distribution makes the plastic deformation of the flat wire 10 more sufficient, and the elastic recovery amount is greatly reduced.

[0089] Specifically, the number of the second bending block 311 is two, which are located at different radial directions of the first bending block 330, and the distance from the first bending block 330 to the center is equal.

[0090] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
