Description

Technical Field

[0001] This application belongs to the field of wire bending technology, specifically relating to a fully automatic wire bending machine and bending process. Background Technology

[0002] The bending process of high-end metal wires refers to the complex, precise, and stable plastic deformation process of metal wires with special alloy composition, excellent mechanical properties (such as high strength, high elasticity, fatigue resistance, and corrosion resistance) and precise dimensional tolerances.

[0003] Automotive wiring harnesses are a type of high-end metal wire, often referred to as the neural network system of a car, and are considered the sixth major component assembly. Currently, the industry mostly uses fully automated wire crimping machines, where wire length cutting, stripping, and terminal crimping are completed in combination.

[0004] With the development needs of the automotive industry for lightweighting, intelligentization, and electrification, 0.22TG high-strength small-section alloy wire has been successfully developed. While there are numerous specifications and models of wire harness terminals both internationally and domestically, 0.22mm... 2 There are almost no compatible terminal models for direct crimping of small wires, and developing them one by one would be too costly. If the traditional manual bending process is used, the production efficiency is low, the quality consistency cannot be guaranteed, the labor cost is high, and the labor intensity is high, which cannot meet the needs of large-scale automated production and thus prevents its widespread application. Summary of the Invention

[0020] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a fully automatic wire bending machine 10, which is suitable for bending high-end metal wires, especially automotive wiring harnesses. It can automatically bend the wire cores and then directly crimp them, thereby significantly reducing labor costs and improving efficiency and quality assurance.

[0022] Figure 1 A schematic diagram of the structure of a fully automatic wire bending machine 10 according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 Structural diagram with the second vertical plate 130 removed. Figure 3 It shows Figure 2 A frontal view diagram. Combined with... Figures 1-3 The fully automatic wire bending machine 10 provided in this application includes a frame 100 and a main wire clamp assembly 200, an auxiliary wire clamp assembly 300, a wire bending assembly 400 and a wire pushing assembly 500 connected to the frame 100. By controlling the operation of the main wire clamp assembly 200, the auxiliary wire clamp assembly 300, the wire bending assembly 400 and the wire pushing assembly 500 of the bending machine 10, the automatic bending processing of the wire ends can be realized.

[0023] Combination Figure 2 as well as Figure 3The main clamp assembly 200 of the bending machine 10 includes a first clamping mechanism 210 and a second clamping mechanism 220 spaced apart along a first direction Y. The first clamping mechanism 210 has a first clamping portion 211, and the second clamping mechanism 220 has a second clamping portion 221. The first clamping portion 211 and the second clamping portion 221 move towards or away from each other along the first direction Y. When the first clamping portion 211 and the second clamping portion 221 move towards each other, the first clamping portion 211 and the second clamping portion 221 enclose and form a first clamping space. The auxiliary clamp assembly 300 is disposed on one side of the main clamp assembly 200 along a second direction X perpendicular to the first direction Y. The auxiliary clamp assembly 300 includes a third clamping mechanism 310 and a fourth clamping mechanism 320 spaced apart along the first direction Y. The third clamping mechanism 310 has a third clamping portion 311, and the fourth clamping mechanism 320 has a fourth clamping portion 321. 311 and the fourth clamping part 321 move towards or away from each other along the first direction Y. Under the condition that the first clamping part 211 and the second clamping part 221 move towards each other, and the third clamping part 311 and the fourth clamping part 321 move towards each other, the first clamping part 211 and the second clamping part 221 enclose each other to form a second clamping space. The second clamping space and the first clamping space are arranged sequentially along the second direction X. Along the second direction X, the main wire clamp assembly 200, the auxiliary wire clamp assembly 300 and the folded wire assembly 400 are arranged sequentially. The folded wire assembly 400 has a folded wire part 410 that moves back and forth along the second direction X. The folded wire part 410 moves back and forth toward the fourth clamping part 321. Along the second direction X, the main wire clamp assembly 200, the auxiliary wire clamp assembly 300 and the push wire assembly 500 are arranged sequentially. The folded wire assembly 400 has a push wire part 510 that moves back and forth along the second direction X. The push wire part 510 is located below the second clamping space.

[0024] For ease of description, the bending machine 10 is now defined to have a height direction, a length direction, and a thickness direction, wherein the height direction is the first direction Y mentioned above, and the length direction is the second direction X mentioned above. The specific configuration details of the bending machine 10 will now be further described with reference to the accompanying drawings.

[0025] Combination Figures 1-3In some embodiments, the frame 100 includes a base 110, a first upright plate 120, a second upright plate 130, an air source 140, an electrical control cabinet 150, and a control valve group 160. The base 110 is the carrier of the entire bending machine 10 and can be installed on a fully automatic wire crimping machine or other wire harness processing equipment. The base 110 has a waist-shaped hole extending along the length direction to adjust the position of the base 110 in the length direction on the processing equipment. In addition, the height of the frame 100 can be adjusted by replacing the base 110 with different heights. The first upright plate 120 and the second upright plate 130 are arranged opposite to each other and extend along the height direction, connecting to the top surface of the base 110. The main wire clamp assembly 200, auxiliary wire clamp assembly 300, folding wire assembly 400, and push wire assembly 500 are all connected to one of the first upright plate 120 and the second upright plate 130, that is, the main wire clamp assembly 200, auxiliary wire clamp assembly 300, folding wire assembly 400, and push wire assembly 500 are arranged between the first upright plate 120 and the second upright plate 130 to ensure safety during construction. For example, the main wire clamp assembly 200, auxiliary wire clamp assembly 300, folding wire assembly 400, and push wire assembly 500 are all arranged on the side of the first upright plate 120 facing the second upright plate 130, that is, on the inner side of the first upright plate 120.

[0026] Additionally, the air source 140 can be connected to the side of the first upright plate 120 or the second upright plate 130 via a bracket to provide clean compressed air for the main wire clamp assembly 200, auxiliary wire clamp assembly 300, wire bending assembly 400, and wire pushing assembly 500. The electrical control cabinet 150 is installed on the top surface of the first upright plate 120 and the second upright plate 130 and serves as the electrical control assembly. The solenoid valve group is connected to the side of the first upright plate 120 to realize the cutting off and connection of the air source 140. Of course, the air source 140, electrical control cabinet 150, and control valve group 160 constituting the frame 100 can also be adjusted according to the actual layout, and this application does not impose any restrictions on this.

[0027] Combination Figure 2 as well as Figure 3 In some embodiments, the main clamp assembly 200 has a symmetrical structure, that is, the first clamping mechanism 210 and the second clamping mechanism 220 are arranged opposite to each other. The first clamping mechanism 210 is located above the second clamping mechanism 220, and its main function is to position and fix the wire to be processed. Under the condition that the first clamping part 211 of the first clamping mechanism 210 and the second clamping part 221 of the second clamping mechanism 220 move towards each other, the wire is positioned and fixed within the first clamping space enclosed by the first clamping part 211 and the second clamping part 221. Since the first clamping mechanism 210 and the second clamping mechanism 220 are arranged opposite to each other, the arrangement details of the first clamping mechanism 210 and the second clamping mechanism 220 will be further described using the first clamping mechanism 210 as an example.

[0028] Figure 4 A schematic diagram of the structure of the first clamping mechanism 210 is shown. Figure 5 It shows Figure 4 A structural diagram from another perspective. Combined with... Figure 4 as well as Figure 5 In some embodiments, the first clamping mechanism 210 includes a telescopic member 212, which is connected to the frame 100 and has a reciprocating telescopic end. The first clamping part 211 of the first clamping mechanism 210 is connected to the telescopic end of the telescopic member 212. By controlling the movement of the telescopic member 212, the first clamping part 211 can be driven to reciprocate along the height direction. For example, the telescopic member 212 can be a cylinder, which has the characteristics of rapid and reliable response. The telescopic member 212 is connected to the inner side of the first upright plate 120. In other embodiments, the telescopic member 212 can also be other linear mechanisms, such as ball screws, linear guides, etc., and this application does not limit this.

[0029] Combination Figure 4 as well as Figure 5 In some embodiments, the first clamping mechanism 210 further includes a slider 213 and a slide rail 214. The slider 213 is connected to the telescopic end of the telescopic member 212, and the first clamping part 211 is connected to the slider 213, that is, the first clamping part 211 is connected to the telescopic end of the telescopic member 212 through the slider 213; the slide rail 214 is connected to the frame 100, and the slider 213 and the slide rail 214 are slidably engaged to guide the movement direction of the first clamping part 211. For example, the slide rail 214 is connected to the inner side of the first upright plate 120, and the slider 213 is provided with a groove facing the side of the first upright plate 120. At least a portion of the slide rail 214 slides in the groove to limit the movement direction of the slider 213, thereby guiding the movement direction of the first clamping part 211 by guiding the movement direction of the slider 213.

[0030] Combination Figure 4 as well as Figure 5In some embodiments, the first clamping mechanism 210 further includes a fixing block 215 and a limiting block 216. The fixing block 215 is connected to the frame 100, and the slider 213 slides through the fixing block 215. The limiting block 216 is connected to the slider 213 and is disposed between the fixing block 215 and the telescopic member 212. The limiting block 216 can move synchronously with the slider 213 and abut against the fixing block 215. With this arrangement, the movement range of the limiting block 216 can be limited by the fixing block 215, thereby achieving the purpose of limiting the movement range of the slider 213 and the first clamping part 211. For example, the fixing block 215 is connected to the inner side of the first upright plate 120. The fixing block 215 has a through groove 2151 on the side facing the first upright plate 120. The slide rail 214 and the slider 213 both pass through the groove 2151. The limiting block 216 can be integrally formed and connected to the outer side of the slider 213. When the first clamping part 211 of the first clamping mechanism 210 and the second clamping part 221 of the second clamping mechanism 220 move towards each other to clamp the wire, the limiting block 216 abuts against the fixing block 215.

[0031] Combination Figure 4 as well as Figure 5 In some embodiments, the first clamping mechanism 210 further includes a limiting post 217, which is disposed along the first direction Y and connected to the fixing block 215. One axial end of the limiting post 217 protrudes from the fixing block 215 toward the telescopic member 212. The limiting block 216 and the axial end of the limiting post 217 are in flexible contact. When the first clamping part 211 of the first clamping mechanism 210 and the second clamping part 221 of the second clamping mechanism 220 move toward each other to clamp the wire, the limiting block 216 abuts against the axial end of the limiting post 217 to limit the movement of the slider 213 and the first clamping part 211. Because the axial end of the limiting block 216 and the limiting post 217 are in flexible contact, the noise generated when the limiting block 216 and the limiting post 217 abut against each other can be reduced, and the service life can be improved. For example, the limiting post 217 can be threaded to the fixing block 215, and a rubber gasket can be attached to one axial end of the limiting post 217.

[0032] Combination Figure 4 as well as Figure 5In some embodiments, the first clamping part 211 and the second clamping part 221 are inserted into each other. When the first clamping part 211 of the first clamping mechanism 210 and the second clamping part 221 of the second clamping mechanism 220 move toward each other to clamp the wire, the clamping effect on the wire located in the first clamping space can be improved because the first clamping part 211 and the second clamping part 221 are inserted and engaged with each other. For example, one end of the first clamping part 211 and one end of the second clamping part 221 can be connected to the side of the corresponding slider 213 through the side plate 218. The other end of the first clamping part 211 and the other end of the second clamping part 221 are provided with slots 219 that can be inserted into each other. When the first clamping part 211 of the first clamping mechanism 210 and the second clamping part 221 of the second clamping mechanism 220 move towards each other to clamp the wire, the slots 219 of the other end of the first clamping part 211 and the other end of the second clamping part 221 can be inserted into each other to improve the clamping effect on the wire located in the first clamping space.

[0033] The structures of the second clamping mechanism 220, the third clamping mechanism 310, the fourth clamping mechanism 320, the folding line assembly 400, and the pushing line assembly 500 are similar to those of the first clamping mechanism 210, with the only difference being the different moving positions of the output section (the first clamping section 211, the second clamping section 221, the third clamping section 311, the fourth clamping section 321, the folding line section 410, and the pushing line section 510). For specific details of the second clamping mechanism 220, the third clamping mechanism 310, the fourth clamping mechanism 320, the folding line assembly 400, and the pushing line assembly 500, please refer to the relevant description of the first clamping mechanism 210, which will not be repeated here.

[0034] It should be noted that in some embodiments, the telescopic members 212 of the first clamping mechanism 210, the second clamping mechanism 220, the third clamping mechanism 310, the fourth clamping mechanism 320, the folding line assembly 400, and the pushing line assembly 500 can all be of the same type, such as cylinders, or they can be of different types. For example, the telescopic members 212 of the first clamping mechanism 210, the second clamping mechanism 220, the third clamping mechanism 310, and the fourth clamping mechanism 320 can be cylinders, while the telescopic members 212 of the folding line assembly 400 and the pushing line assembly 500 can be linear guides, etc. The specific arrangement can be adjusted according to the actual situation, and this application will not elaborate on this.

[0035] Figure 6 An assembly diagram of the auxiliary wire clamp assembly 300, the folding wire assembly 400, and the push wire assembly 500 is shown. Figure 6As shown, in some embodiments, the third clamping mechanism 310 is disposed to the right of the first clamping mechanism 210, and the fourth clamping mechanism 320 is disposed to the right of the second clamping mechanism 220. The third clamping part 311 of the third clamping mechanism 310 reciprocates close to the vertical side of the first clamping part 211; the fourth clamping part 321 of the fourth clamping mechanism 320 reciprocates close to the vertical side of the second clamping part 221. This arrangement can prevent the wire from deforming between the main clamping assembly and the auxiliary clamping host when the bending assembly 400 and the pushing assembly 500 apply force to the end of the wire, thus avoiding affecting the quality of the wire bending process.

[0036] Combination Figure 6 In some embodiments, the bending assembly 400 is disposed on the right side of the third clamping mechanism 310, and the bending portion 410 of the bending assembly 400 reciprocates along an inclined direction toward the fourth clamping mechanism 320 to bend the end of the wire at a certain angle.

[0037] Combination Figure 1 In some embodiments, when the third clamping part 311 and the fourth clamping part 321 move towards each other, the side of the third clamping part 311 and the fourth clamping part 321 facing away from the main wire clamp assembly 200 forms an inclined plane 330, and the bending part 410 moves back and forth close to the inclined plane 330. This configuration ensures that the angle between the end of the wire bent by the bending part 410 of the bending assembly 400 and the wire body is acute. Consequently, under the action of the pushing part 510 of the pushing assembly 500, the bent end of the wire can be further bent along a predetermined direction, preventing the end of the wire from bending in other directions and ensuring the bending quality of the wire end. Exemplarily, the inclination angle of the inclined plane 330 can be 60°-80°, for example, 60°, 65°, 70°, 75°, 80° or any value between the two, and this application does not limit this.

[0038] Figure 7 A schematic diagram of the third clamping part 311 is shown. Figure 8 A schematic diagram of the fourth clamping part 321 is shown. Figure 9 A schematic diagram of the structure of the broken line portion 410 is shown. Figure 10 A schematic diagram of the push-wire section 510 is shown. (Combined with...) Figures 7-10 In some embodiments, receiving grooves S are provided on the opposite sides of the third clamping part 311 and the fourth clamping part 321, the end of the bending part 410, and the side of the pusher part 510 facing the third clamping part 311. This arrangement ensures that when the third clamping part 311 and the fourth clamping part 321 clamp the wire, the bending part 410 and the pusher part 510 act on the wire, the wire is contained within the receiving grooves S, allowing the wire to move only in a predetermined direction, thus preventing movement in other directions and improving the bending quality of the end of the alarm wire.

[0039] Based on the aforementioned fully automatic wire bending machine 10, this application also provides a wire bending process, which includes: S1: Combination Figure 11 The system provides a wire 20 and places the provided wire 20 between the first clamping part 211 and the second clamping part 221 of the main wire clamp assembly 200. In specific implementation, after the processing host completes the fixed-length cutting and fixed-length stripping process of the wire 20, when the wire 20 moves to the bending process, the wire 20 to be bent is transferred between the first clamping part 211 and the second clamping part 221 of the main wire clamp assembly 200. At this time, all the telescopic parts 212 of the wire 20 bending machine 10 are in a stopped state. When the wire 20 is in place, the wire 20 arrival signal is sent to the electrical control cabinet 150. S2: Combination Figure 12 The main clamp assembly 200 is controlled to move, with the first clamping part 211 and the second clamping part 221 moving towards each other. The provided wire 20 is clamped between the first clamping part 211 and the second clamping part 221, with the end of the wire 20 protruding from the first clamping space towards the second clamping space. In specific implementation, after the control cabinet 150 receives the signal that the wire 20 has arrived, it controls the extension members 212 of the first clamping mechanism 210 and the second clamping mechanism 220 of the main clamp assembly 200 to start. The first clamping part 211 of the first clamping mechanism 210 and the second clamping part 221 of the second clamping mechanism 220 move towards each other to clamp the wire 20 to be processed. At the same time, an arrival signal is given to the control cabinet 150. S3: Combination Figure 13 as well as Figure 14 The auxiliary clamp assembly 300 is controlled to move, causing the third clamping part 311 and the fourth clamping part 321 to move towards each other. The provided wire 20 passes through the space between the third clamping part 311 and the fourth clamping part 321, with the end of the wire 20 protruding from the second clamping space and facing away from the first clamping space. In specific implementation, the fourth clamping part 321 located below is controlled to move, so as to hold the wire 20 through the fourth clamping part 321 and give a positioning signal to the electrical control cabinet 150. Subsequently, the third clamping part 311 located above is controlled to move, and the third clamping part 311 and the fourth clamping part 321 abut against each other. The third clamping part 311 presses down on the wire 20, thereby further positioning and clamping the wire 20 between the third clamping part 311 and the fourth clamping part 321, and giving a positioning signal to the electrical control cabinet 150.

[0040] S4: Combination Figure 15 as well as Figure 16The bending assembly 400 is controlled to move, and the bending part 410 presses against the end of the wire 20 so that the end of the wire 20 bends towards the fourth clamping part 321 and then returns to its original position. In specific implementation, the bending part 410 of the bending assembly 400 is extended and moves towards the fourth clamping part 321 in an inclined direction, and acts on the end of the wire 20 protruding from the second clamping space so that the end of the wire 20 bends downward to a certain angle. After the bending part 410 is in place, it immediately returns and gives a completion signal to the electrical control cabinet 150. S5: Combination Figure 17 The fourth clamping part 321 of the auxiliary clamp assembly 300 is controlled to return to its original position. In specific implementation, the fourth clamping part 321 of the fourth clamping mechanism 320 is controlled to return to its original position, thereby providing space for further bending of the end of the wire 20 and giving a positioning signal to the electrical control cabinet 150. S6: Combination Figure 18 as well as Figure 19 The control pusher assembly 500 is activated, and the pusher part 510 pushes the bent end of the wire 20 to a set position and then returns to its original position. In specific implementation, the pusher part 510 of the control pusher assembly 500 extends, pushes the bent end of the wire 20, and further bends the end of the wire 20 to increase the bending angle of the end of the wire 20. After the pusher part 510 reaches its position, it immediately retracts and gives a signal to the control cabinet 150. S7: Combination Figure 20 The fourth clamping part 321 of the auxiliary wire clamp assembly 300 is moved towards the third clamping part 311, driving the bent end of the wire 20 to adhere to the wire 20 body located on the third clamping part 311, thus completing the folding of the end of the wire 20. In specific implementation, the fourth clamping part 321 of the control fourth drive mechanism extends, the fourth clamping part 321 abuts against and pushes the end of the wire 20, so that the end of the wire 20 is completely folded, and a positioning signal is given to the electrical control cabinet 150; S8: Combination Figure 21 The third clamping part 311 and the fourth clamping part 321 of the auxiliary clamp assembly 300 are returned to their original positions, and a positioning signal is sent to the electrical control cabinet 150. S9: Combination Figure 22 The first clamping part 211 and the second clamping part 221 of the auxiliary wire clamp assembly 300 are returned to their original positions, and a positioning signal is sent to the electrical control cabinet 150. At this time, the bending action of the end of the wire 20 is completed, the main unit transfers the wire 20 to be processed to the next process, the entire bending process is completed, and the next cycle begins.

[0041] In the bending process described above, the positioning of each component can be achieved by a camera mounted on the frame 100 or by a displacement sensor mounted on the telescopic component 212. The movement of each component can be completed fully automatically under the control of the electrical control cabinet 150, without relying on manual labor, resulting in excellent processing efficiency. In summary, the fully automatic wire bending machine 10 and bending process provided in this application are suitable for bending high-end metal wires. By controlling the actions of the main wire clamp assembly 200, auxiliary wire clamp assembly 300, wire bending assembly 400 and wire pushing assembly 500 of the bending machine 10, automatic bending of wire ends can be achieved, thereby saving labor costs and ensuring production efficiency and crimping quality to meet the needs of large-scale industrial intelligent production.
