Description

Technical Field

[0001] This utility model relates to an alternating translational feeding mechanism and processing equipment. Background Technology

[0002] Some cable products have multiple wires, each with a different type of terminal block at its end, and each wire also has a different length. To automate the production of these products, typical processing equipment includes two main processes: stripping and terminal crimping, and wire drawing and cutting. The terminal crimping process has multiple stations for different types of terminals. The multiple wires mounted on the fixture need to be terminal crimped one by one before they can be moved to the wire drawing and cutting station for processing. This results in the wire drawing and cutting station being idle during the stripping and terminal crimping process, and vice versa, ultimately leading to low production efficiency. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of this utility model is to provide an alternating translational feeding mechanism that can simultaneously handle two processes to improve production efficiency; another objective is to provide a processing equipment employing the above-mentioned alternating translational feeding mechanism.

[0004] An alternating translational wire feeding mechanism according to a first aspect of the present invention includes: a first slide rail and a second slide rail arranged parallel to each other on a worktable, the first slide rail being closer to the processing station than the second slide rail, a first sliding seat and a second sliding seat being slidably disposed on the first slide rail and the second slide rail respectively, a disassembly fixture being disposed on the first sliding seat, a first wire feeding device being detachably disposed on the disassembly fixture, a second wire feeding device being disposed on the second sliding seat extending toward the first slide rail, a height space between the second wire feeding device and the first slide rail for the first sliding seat and the disassembly fixture to reciprocate through, and a moving device being disposed on the worktable to drive the first wire feeding device and the disassembly fixture to separate.

[0005] The alternating translational wire feeding mechanism according to the embodiments of the present utility model has at least the following beneficial effects:

[0006] The processing station includes a pre-process station and a post-process station. When the first wire feeding device supplies wires to the pre-process station, the second wire feeding device supplies wires to the post-process station. After the wires on the first wire feeding device have completed the pre-process processing, the first sliding seat transports the first wire feeding device to the position of the moving device. The moving device can remove the first wire feeding device from the disassembly / assembly fixture. The second wire feeding device, with the help of the height space, can pass over the disassembly / assembly fixture to move to the pre-process station. Then, the moving device reassembles the first wire feeding device onto the disassembly / assembly fixture. The first sliding seat transports the first wire feeding device to the post-process station. At this time, the positions of the first and second wire feeding devices are exchanged. The wires on the first wire feeding device, after completing the pre-process processing, can continue to be processed in the post-process. After processing, the second wire feeding device can carry the wire to be processed and restart the previous process. When the wire on the second wire feeding device has completed the previous process, and the wire on the first wire feeding device has completed the next process, the first sliding seat transports the first wire feeding device to the position of the moving device. The moving device can remove the first wire feeding device from the disassembly and assembly fixture. The second wire feeding device can pass over the disassembly and assembly fixture to move to the next process station with the help of the height space. Then the moving device reassembles the first wire feeding device onto the disassembly and assembly fixture. The first sliding seat transports the first wire feeding device to the previous process station. At this time, the first and second wire feeding devices exchange positions again. This process is repeated, so that the previous process station and the next process station do not need to wait, thereby improving production efficiency.

When the front claw and the rear claw approach each other, the second wedge surface moves on the first wedge surface to make the first positioning post insert into the corresponding first positioning through hole until the upper mounting plate abuts against the bottom wall of the first box body.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] See Figure 1 , Figure 2 and Figure 6 The present invention discloses an alternating translational wire feeding mechanism, comprising: a first slide rail 110 and a second slide rail 120 arranged parallel to each other on a worktable 100. The first slide rail 110 is closer to the processing station than the second slide rail 120. A first sliding seat 210 and a second sliding seat 220 are slidably arranged on the first slide rail 110 and the second slide rail 120, respectively. A disassembly fixture 300 is provided on the first sliding seat 210. A first wire feeding device 400 is detachably provided on the disassembly fixture 300. A second wire feeding device 500 is provided on the second sliding seat 220 extending toward the first slide rail 110. There is a height space between the second wire feeding device 500 and the first slide rail 110 for the first sliding seat 210 and the disassembly fixture 300 to reciprocate. A moving device 600 is provided on the worktable 100 to drive the first wire feeding device 400 and the disassembly fixture 300 to separate.

[0031] The processing station includes a pre-process station and a post-process station. When the first wire feeding device 400 supplies wires to the pre-process station, the second wire feeding device 500 supplies wires to the post-process station. After the wires on the first wire feeding device 400 have completed the pre-process processing, the first sliding seat 210 transports the first wire feeding device 400 to the position of the moving device 600. The moving device 600 can remove the first wire feeding device 400 from the disassembly / assembly fixture 300. The second wire feeding device 500 can move to the pre-process station by passing over the disassembly / assembly fixture 300 using the height space. Then, the moving device 600 reassembles the first wire feeding device 400 onto the disassembly / assembly fixture 300. The first sliding seat 210 transports the first wire feeding device 400 to the post-process station. At this time, the positions of the first wire feeding device 400 and the second wire feeding device 500 are exchanged. The wires on the first wire feeding device 400, after completing the pre-process processing, can continue to be processed in the post-process station. After the initial processing, the second wire feeding device 500 can carry the wire to be processed and restart the previous processing. When the wire on the second wire feeding device 500 has completed the previous processing, the wire on the first wire feeding device 400 has completed the next processing. The first sliding seat 210 transports the first wire feeding device 400 to the position of the moving device 600. The moving device 600 can remove the first wire feeding device 400 from the disassembly and assembly fixture 300. The second wire feeding device 500 can pass over the disassembly and assembly fixture 300 to move to the next processing station by taking advantage of the height space. Then, the moving device 600 reassembles the first wire feeding device 400 onto the disassembly and assembly fixture 300. The first sliding seat 210 transports the first wire feeding device 400 to the previous processing station. At this time, the first wire feeding device 400 and the second wire feeding device 500 exchange positions again. The above steps are repeated, so that the previous and next processing stations do not need to wait, thereby improving production efficiency.

[0032] See Figure 1 , Figure 3 and Figure 4In some embodiments of this utility model, the first wire feeding device 400 is externally connected to an installation frame 410. The upper end and lower end of the installation frame 410 are respectively provided with an upper installation plate 411 and a lower installation plate 412. The moving device 600 includes a lifting platform 610 located outside the first slide rail 110. The lifting platform 610 is provided with a first gripper mechanism 620 for clamping the upper installation plate 411, and the disassembly fixture 300 is provided with a second gripper mechanism 310 for clamping the lower installation plate 412. It can be understood that the disassembly fixture 300 uses the second gripper mechanism 310 to clamp and fix the lower installation plate 412 of the installation frame 410, thereby fixing the first wire feeding device 400 on the first sliding seat 210. The first wire feeding device 400 can reciprocate between the previous process station and the next process station along the first slide rail 110 with the first sliding seat 210. When it is necessary to avoid the second wire feeding device 500 so that the second wire feeding device 500 can reciprocate between the previous process station and the next process station along the second slide rail 120 following the second sliding seat 220, the first sliding seat 210 moves to the vicinity of the moving device 600, the lifting platform 610 descends, the first gripper mechanism 620 clamps the upper mounting plate 411 of the fixed mounting frame 410, and the second gripper mechanism 310 releases the lower mounting plate 412 of the mounting frame 410, thereby fixing the first wire feeding device 400 on the lifting platform 610. Then the lifting platform 610 moves upward to reset, allowing the second wire feeding device 500 to pass over the disassembly and assembly fixture 300, that is, the disassembly and assembly fixture 300 and the first sliding seat 210 can pass through the height space. The installation and disassembly of the first wire feeding device 400 using the first gripper mechanism 620 and the second gripper mechanism 310 is very fast, simple in structure, and low in cost. Of course, in other embodiments, the disassembly fixture 300 and the moving device 600 may also employ other structures such as magnetic fixation or robotic arms.

[0033] See Figure 3In some embodiments of this utility model, the first gripper mechanism 620 and the second gripper mechanism 310 have the same structure. The first gripper mechanism 620 includes a first box 621 fixed to the lifting platform 610. Two gripper assemblies are spaced apart in the first box 621 along a direction parallel to the first slide rail 110. The gripper assembly includes a front gripper 622 and a rear gripper 623 spaced apart along a direction perpendicular to the first slide rail 110. The front gripper 622 and the rear gripper 623 are respectively connected to a first rack 624 and a second rack 625. A gear 626 is rotatably disposed in the first box 621 and meshes with the first rack 624 and the second rack 625. The first rack 624 or the second rack 625 is connected to a first cylinder 627 that drives it to extend and retract in a direction perpendicular to the first slide rail 110. When the first cylinder 627 drives the first rack 624 or the second rack 625 to move along its length, the front gripper 622 and the rear gripper 623 can move closer or further apart. When the front gripper 622 and the rear gripper 623 move closer together, they clamp the two sides of the upper mounting plate 411. The two gripper assemblies form a four-point support for the upper mounting plate 411, which helps to stably clamp the upper mounting plate 411. Similarly, the second gripper mechanism 310 includes two gripper assemblies fixedly disposed within the disassembly and assembly fixture 300. The structure of the gripper assemblies is completely consistent with the above description and will not be elaborated further here.

[0034] See Figure 3 and Figure 4In some embodiments of this utility model, one of the bottom wall of the first box body 621 and the upper mounting plate 411 is provided with a plurality of vertically upward first positioning posts 413, and the other is provided with first positioning through holes 628 that match the first positioning posts 413 one by one. The upper mounting plate 411 is provided with a notch 414 corresponding to the front claw 622 and the rear claw 623 respectively. A first wedge surface 415 is provided between the upper mounting plate 411 and the notch 414. The front claw 622 and the rear claw 623 are each provided with a second wedge surface 629 that cooperates with the corresponding first wedge surface 415. When the front claw 622 and the rear claw 623 approach each other, the second wedge surface 629 moves on the first wedge surface 415 so that the first positioning post 413 is inserted into the corresponding first positioning through hole 628 until the upper mounting plate 411 abuts against the bottom wall of the first box body 621. It is understandable that the first housing 621 and the lower mounting plate 412 of the mounting frame 410 are also assembled through two gripper assemblies. In order to ensure that the relative position of the first wire feeding device 400 on the first housing 621 is accurate, and thus ensure that the first wire feeding device 400 is accurately installed on the disassembly and assembly fixture 300, thereby ensuring that the terminal crimping, wire pulling and cutting processes can work normally and avoid the formation of defective products. Specifically, when the lifting platform 610 moves downwards until the first housing 621 is close to the upper mounting plate 411, each of the first positioning pins 413 is inserted into the corresponding first positioning through hole 628. At this time, the front gripper 622 and the rear gripper 623 of the two gripper assemblies are in a state of being far apart from each other. As the first cylinder 627 drives the front gripper 622 and the rear gripper 623 to move closer to each other, the front gripper 622 and the rear gripper 623 enter from the two notches 414 respectively. Then, the second wedge surface 629 abuts against the first wedge surface 415 and moves along the first wedge surface 415, thereby driving the first wire feeding device 400 to move upwards relative to the lifting platform 610 until the upper mounting plate 411 contacts the bottom surface of the first housing 621. The first positioning pins 413 can then be inserted into place along the depth direction of the first positioning through hole 628, and the front gripper 622 and the rear gripper 623 clamp and fix the upper mounting plate 411.

[0035] It should be noted that the assembly / disassembly fixture 300 and the lower mounting plate 412 of the mounting frame 410 are also assembled via two gripper assemblies. To ensure the precise relative position of the first wire feeding device 400 on the assembly / disassembly fixture 300, thereby ensuring the normal operation of processes such as wire terminal crimping and wire cutting, and avoiding the formation of defective products, the assembly / disassembly fixture 300 is also equipped with two gripper assemblies. The lower mounting plate 412 also has notches 414 on both sides that mate with the two front grippers 622 and the two rear grippers 623. A first wedge-shaped surface 415 is also provided between the lower mounting plate 412 and the notches 414. Both the front grippers 622 and the rear grippers 623 have second wedge-shaped surfaces 629 that mate with the corresponding first wedge-shaped surfaces 415. The assembly and disassembly methods between the assembly / disassembly fixture 300 and the lower mounting plate 412 are as described above and will not be elaborated further.

[0036] See Figures 2 to 4 In some embodiments of this utility model, the disassembly / assembly fixture 300 is connected to a first linear actuator 320 that drives it to slide relative to the first sliding seat 210 in a direction perpendicular to the first slide rail 110. The first wire feeding device 400 includes a plurality of first wire clamping units 420 spaced apart in a direction parallel to the first slide rail 110. Each first wire clamping unit 420 is slidably disposed on the disassembly / assembly fixture 300 via a second linear actuator 430. The sliding direction of the first wire clamping unit 420 is consistent with the sliding direction of the disassembly / assembly fixture 300. It should be noted that when the first wire feeding device 400 on the disassembly / assembly fixture 300 moves to the previous process station or the next process station, the first linear actuator 320 drives the disassembly / assembly fixture 300 and the first wire feeding device 400 to extend toward the processing station together. Each first wire clamping unit 420 is positioned to clamp a wire. When a certain wire needs to be processed, the second linear actuator 430 is used to drive the wire on the corresponding first wire clamping unit 420 to extend to the processing station. For example, when it is necessary to crimp a terminal on a wire, the control unit of the equipment controls the corresponding second linear driver 430 to extend, thereby pushing the end of the wire to the output end of the crimping machine 910.

[0037] See Figure 4In some embodiments of this utility model, the first wire clamping unit 420 includes a sliding frame 421 connected to the output end of the second linear driver 430. The sliding frame 421 is connected to a lifting frame 422 via a vertical spring. The lifting frame 422 is equipped with a wire threading sleeve 423 and a clamping cylinder 424 that clamps the wire against the lifting frame 422. It should be noted that the wire passes through the wire threading sleeve 423, and the clamping cylinder 424 clamps the wire against the lifting frame 422. When performing operations such as terminal crimping, stripping, or cutting on the end of the wire, the lifting frame 422 can compress the vertical spring, causing the wire to move up and down a certain distance, thereby realizing the terminal crimping, stripping, and cutting operations. It is conceivable that the second wire feeding device 500 has the same overall structure as the first wire feeding device 400, thus enabling it to match the processing station and complete the same operations. Specifically, the second wire feeding device 500 includes a slide plate that is slidably disposed on the overhang plate 230 in a direction perpendicular to the second slide rail 120. The slide plate is provided with a plurality of second wire clamping units at intervals in a direction parallel to the second slide rail 120. Each second wire clamping unit is slidably disposed on the slide plate by a third linear actuator. The sliding direction of the second wire clamping unit is consistent with the sliding direction of the slide plate.

[0038] See Figure 1 and Figure 2 In some embodiments of this utility model, the second sliding seat 220 is provided with an extension plate 230 extending toward the first slide rail 110. The height space is located between the extension plate 230 and the first slide rail 110. The first linear actuator 320 includes a first lead screw rotatably disposed on the first sliding seat 210. The bottom of the disassembly fixture 300 is provided with a first threaded sleeve that cooperates with the first lead screw. The first sliding seat 210 is provided with a synchronous belt pulley mechanism connected to one end of the first lead screw on one side of the disassembly fixture 300. It can be understood that the extension plate 230 extends above the outer edge of the first slide rail 110, thereby allowing the second wire feeding device 500 to approach the processing station. The first wire feeding device 400 is raised above the second wire feeding device 500 by the lifting platform 610. At this time, the first sliding seat 210 can drive the disassembly fixture 300 to pass through the height space. The first linear driver 320 with the above structure is advantageous in shortening the distance between the first slide rail 110 and the second slide rail 120, thereby reducing the width dimension of the alternating translational wire feeding mechanism and improving the compactness of the equipment.

[0039] See Figure 5In some embodiments of this utility model, the moving device 600 includes a lifting platform 610 located outside the first slide rail 110. The lifting platform 610 is provided with a first gripper mechanism 620 of the first wire feeding device 400. The second linear actuator 430 is a second cylinder. Each second cylinder is connected to a solenoid valve 710 that controls its opening and closing. The side of the first wire feeding device 400 is provided with a first plug-in terminal 720 that is electrically connected to all the solenoid valves 710. The disassembly and assembly fixture 300 is provided with a second plug-in terminal 730 that cooperates with the first plug-in terminal 720.

[0040] It should be noted that the second cylinder is a double-stroke cylinder to stably drive the first wire clamping unit 420 to extend and retract toward the processing station. However, double-stroke cylinders require a solenoid valve 710. The control unit and power cable of the processing equipment are located below the worktable 100, that is, below the first slide rail 110 and the second slide rail 120. If the power cable is directly connected to the solenoid valve 710 of the first wire feeding device 400 from below, when the first gripper mechanism 620 of the lifting platform 610 grips the first wire feeding device 400 and moves upward, the power cable not only needs to be of a longer length, but also is prone to interference with the second wire feeding device 500 on the second sliding seat 220 when the first wire feeding device 400 and the second wire feeding device 500 interchange positions. The above-mentioned method of using the first plug-in terminal 720 and the second plug-in terminal 730 can completely solve this technical problem.

[0041] See Figure 1 and Figure 2 In some embodiments of this utility model, both the first wire feeding device 400 and the second wire feeding device 500 are provided with a guide limiting device 800 for guiding the wire to extend and preventing the wire from moving. Specifically, the guide limiting device 800 includes multiple rows of fixed guide wheel groups arranged at intervals, and a row of movable guide wheel groups is provided between two adjacent rows of fixed guide wheel groups. The movable guide wheel groups are slightly misaligned relative to the fixed guide wheel groups so that the passing wire is in a taut state. The guide limiting device 800 with the above structure is a technical content well known to those skilled in the art and will not be described in detail here.

[0042] See Figure 6This utility model also discloses a processing equipment, including a workbench 100, which is equipped with an alternating translational wire feeding mechanism according to any of the above-mentioned technical solutions. Specifically, the front-end station on the workbench 100 has multiple terminal machines 910, the back-end station on the workbench 100 has a wire pulling and cutting machine 920, and the moving device 600 is located between the front-end station and the back-end station. When the first wire feeding device 400 feeds the end of the wire into the terminal crimping machine 910, the terminal crimping machine 910 rivets a terminal onto the end of the wire. At the same time, the wire pulling and cutting machine 920 stretches the wire on the second wire feeding device 500 a certain distance and then cuts it, that is, the wire with the terminal is separated from the second wire feeding device 500. At this time, the second wire feeding device 500 carries wires that have not yet been riveted with terminals. Then, using the alternating translational wire feeding mechanism of the above structure, the positions of the first wire feeding device 400 and the second wire feeding device 500 are interchanged. The wires on the first wire feeding device 400 that have completed the terminal crimping can continue to complete the process of stretching a certain distance and then cutting, while the wires to be processed on the second wire feeding device 500 begin the process of terminal crimping. The above steps are repeated, thereby achieving the effect that both terminal crimping and wire pulling and cutting functions do not require waiting, thereby improving production efficiency.

[0043] 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.
