Description

Technical Field

[0001] The present invention relates to the technical field of metal processing equipment, and in particular to an automated metal sheet tying ring device and method thereof. Background Art

[0002] After small metal sheets such as clip pieces and gasket pieces are stamped and formed, surface treatment is often required through an electroplating process. Since it is difficult to fix the metal sheets, before electroplating, iron wires need to be threaded through the inner holes of the metal sheets and tied into a circular ring shape to facilitate batch degreasing, pickling, electroplating and other processes. The traditional method of tying rings relies on manual operation. Workers need to manually sort the metal sheets, thread the iron wires, bend and shape them, and tie them tightly. This method is prone to occupational diseases due to repetitive labor, and there is also a risk of workers being scratched by the iron wires. Therefore, there is an urgent need for an integrated device that can automatically complete the material separation, threading, cutting, bending and shaping, and tying of metal sheets, so as to improve production efficiency and ensure the personal health of workers. Summary of the Invention

[0003] In order to overcome the deficiencies of the background art, the technical solution adopted by the present invention is: an automated metal sheet tying ring device, including a workbench, a feeding mechanism, a threading mechanism, and a tying ring mechanism provided on the workbench, and a moving mechanism and a vibrating disc provided on both sides of the workbench;

[0004] The threading mechanism includes a wire wheel, a roller group, a wire threading tube, a lifting seat, and a cutting seat. The iron wire in the wire wheel extends to the inside of the wire threading tube through the roller group. The feeding mechanism sequentially threads the metal sheets in the vibrating disc onto the iron wire. The wire threading tube is connected to the lifting seat, and cutting seats for cutting the iron wire are provided on both sides of the lifting seat. The moving mechanism bends the iron wire into a ring and moves it to the tying ring mechanism, and the tying ring mechanism binds and shapes the iron wire.

[0005] The present invention provides an automated metal sheet tying ring method, and the steps are as follows:

[0006] S1. Prepare metal sheets and iron wires;

[0007] S2. Thread and stack the metal sheets;

[0008] S3. Clamp the iron wire;

[0009] S4. Cut the iron wire;

[0010] S5. Shape the iron wire;

[0011] S6. Form the tied ring with the iron wire;

[0012] S7. Unload the metal sheet group.

[0013] With the above technical solution, the device is generally divided into a vibrating disk and a feeding mechanism for conveying metal sheets, a wire threading mechanism for conveying and cutting iron wires, a moving mechanism for shaping the metal sheets into rings, and a wire tying mechanism for locking the iron wires, so as to realize the full automation of processes such as threading and stacking metal sheets, cutting iron wires, shaping iron wires, and forming wire tying of iron wires. The workload of workers is simplified. Workers only need to add materials at the vibrating disk and the wire reel and take materials at the discharge track, and the operation space of workers is on one side of the device, greatly improving convenience and safety. At the same time, the consistency of the structure after the metal sheets are stacked is ensured, providing a stable structural basis for the subsequent electroplating process.

[0014] The present invention is further configured such that the feeding mechanism includes a feeding track, a material distributing seat, a cam manipulator, a material blocking fixture, and a material blocking plate. The vibrating disk conveys the metal sheets to the material distributing seat through the feeding track. The material distributing seat conveys the metal sheets to one side of the cam manipulator one by one. On the other side of the cam manipulator, there is a material blocking fixture for assisting wire threading and a material blocking plate for stacking materials. The wire threading tube extends through the material blocking plate to the material blocking fixture.

[0015] The moving mechanism includes a moving frame, a steering plate, a rotating seat, and a wire clamping manipulator. The moving frame moves parallel to the workbench. The moving frame is rotatably connected with a steering plate. The steering plate is symmetrically distributed with rotating seats for bending the iron wires into rings. The rotating seats are connected with wire clamping manipulators for clamping the iron wires.

[0016] The wire tying mechanism includes a locking fixture for clamping both ends of the iron wire, a wire tying motor for tying the iron wire, and a discharge track for discharging.

[0017] The invention is further configured such that one end of the feeding track is provided with an adapter seat and a pressing plate. The adapter seat and the pressing plate form a chute for accommodating the metal sheets in combination. A first sliding table cylinder is provided between the material distributing seat and the workbench. The material distributing seat reciprocates horizontally relative to the adapter seat through the first sliding table cylinder. The material distributing seat is provided with an adapter groove corresponding to the chute. Accommodating grooves are provided on both sides of the adapter groove. The cam manipulator picks up the metal sheets through the accommodating grooves.

[0018] With the above technical solution, the adapter groove is the same length as the metal sheet, and through the limitation of the pressing plate, there is only a single metal sheet passing through the chute, avoiding the stacking of metal sheets, realizing the transfer of metal sheets one by one, avoiding the phenomenon of material jamming, and providing a reliable feeding guarantee.

[0019] The present invention is further configured such that a linear slide rail, a transmission cylinder, and a stop block are provided between the lifting seat and the workbench. The lifting seat is slidably connected to the workbench through the linear slide rail, and one end of the lifting seat is connected with a transmission cylinder for controlling the movement of the wire threading tube. A stop block for limiting is provided at the bottom of the linear slide rail.

[0020] With the above technical solution, the wire threading tube is a hollow tubular structure, which is used to assist in wire threading. During the movement of the wire threading tube, the iron wire is always arranged inside the wire threading tube. When the iron wire slowly moves to the cam manipulator, the wire threading tube quickly moves to the cam manipulator through the transmission cylinder. At this time, the metal sheets are stacked preferentially through the wire threading tube, thus shortening the time of the metal sheet stacking process. And when the iron wire moves upward, the iron wire is straightened by the limitation of the wire threading tube.

[0021] The present invention is further configured such that the material blocking fixture includes a second sliding table cylinder, a parallel cylinder and a clamping jaw. The parallel cylinder is connected to one side of the wire threading tube through the second sliding table cylinder. The output end of the parallel cylinder is connected with a clamping jaw for clamping the wire threading tube. The two clamping jaws form an upper plane for laying the metal sheets flat. The material blocking plate is provided with an opening groove for avoiding the wire threading tube.

[0022] With the above technical solution, when the cam manipulator moves the metal sheet above the wire threading tube, it preferentially falls on the upper plane of the clamping jaw, playing a buffering role to prevent the metal sheet from directly falling on the material blocking plate and deforming. When the moving mechanism clamps the iron wire and moves away from the workbench, the material blocking fixture moves away from the wire threading tube through the second sliding table cylinder, and the iron wire leaves the material blocking plate through the opening groove, avoiding interference. The overall structure is reasonably designed.

[0023] The present invention is further configured such that the roller group includes a driving wheel, a driven wheel, a mounting plate, a side plate and a wire feeding motor. The driving wheel is rotatably connected to one side of the mounting plate, and a wire feeding motor for controlling the rotation of the driving wheel is provided on the other side of the mounting plate. The mounting plate is fixedly connected with a side plate distributed perpendicular / parallel to it, and the side plate is rotatably connected with driven wheels distributed alternately.

[0024] With the above technical solution, each side plate is provided with four driven wheels distributed alternately to form a driven wheel group, so as to increase the friction between the iron wire and the driven wheels and avoid the phenomenon of slipping. There are two groups of driven wheel groups distributed perpendicular to each other below the driving wheel, thereby restricting the radial freedom of the iron wire and realizing the high-precision and stable transmission of the iron wire.

[0025] The present invention is further configured such that the wire wheel is coaxially connected with a rotary encoder, and a photoelectric sensor for detecting the presence of the iron wire is provided on one side of the mounting plate.

[0026] With the above technical solution, the moving amount of the iron wire is measured by the rotary encoder to ensure that the iron wire can move to the specified height each time. The photoelectric sensor is used to detect whether the wire is broken, so that the staff can replace the wire wheel in time.

[0027] The present invention is further configured such that a lead screw module and a third slide table cylinder are provided at the bottom of the moving frame. The moving frame moves horizontally relative to the workbench through the lead screw module, and the moving frame moves longitudinally relative to the workbench through the third slide table cylinder. A steering motor is provided above the moving frame, and the steering plate is controlled to rotate relative to the moving frame through the steering motor. The steering plate is provided with a semi-circular slide rail, a fourth slide table cylinder, and a pull rod. The semi-circular slide rail is slidably connected with symmetrically distributed rotating seats. The fourth slide table cylinder is arranged on the axis of symmetry of the semi-circular slide rail and controls the synchronous movement of the two groups of rotating seats through the pull rod.

[0028] With the above technical solution, the pull rod is rotatably connected to the rotating seat and the fourth slide table cylinder through a universal joint. When the fourth slide table cylinder works, it controls the synchronous movement of the pull rods on both sides, thereby controlling the steering plate to separate or approach along the semi-circular slide rail, meeting the requirements for the wire clamping manipulator to pick up materials and bind rings.

[0029] The present invention is further configured such that the wire clamping manipulator includes an actuator, a rotary joint, a pneumatic chuck, a main chuck, and a sub-chuck. The actuator is rotatably connected to the pneumatic chuck through the rotary joint. The output ends of the pneumatic chuck are respectively fixedly connected with the main chuck and the sub-chuck, and the main chuck and the sub-chuck are combined to form a clamping groove for fixing the iron wire. The two groups of wire clamping manipulators are respectively located above the material blocking fixture and between the material blocking plate and the cutting seat.

[0030] With the above technical solution, the actuator controls the coordinated actions of the rotary joint and the pneumatic chuck respectively. Among them, the pneumatic chuck is used to clamp the iron wire, and the rotary joint is used to adjust the rotation angle of the pneumatic chuck, thereby indirectly adjusting the orientation of the clamping groove.

[0031] The present invention is further configured such that more than two sets of feeding mechanisms are provided on both sides of the workbench where the ring binding mechanism is located.

[0032] With the above technical solution, since the process of stacking metal sheets with wires takes a long time, while the working cycle of the ring binding mechanism is short, multiple sets of feeding mechanisms, wire threading mechanisms, and vibrating bowls work together. For example, after the A group of feeding mechanisms complete stacking, the moving mechanism transfers the metal sheet group of the A group of feeding mechanisms to the ring binding mechanism. During this period, the B group of feeding mechanisms normalizes stacking. Utilizing the time difference generated by the sequential stacking of the two groups of feeding mechanisms, the idle time of the moving mechanism and the ring binding mechanism is reduced, and the production efficiency is improved.

[0051] As Figure 2 shown, in this embodiment, a transfer seat 111 and a pressing plate 112 are provided at one end of the feeding track 11. The transfer seat 111 and the pressing plate 112 are combined to form a chute 113 for accommodating the metal sheet. A first sliding table cylinder 16 is provided between the material distributing seat 12 and the workbench 6. The material distributing seat 12 reciprocates horizontally relative to the transfer seat 111 through the first sliding table cylinder 16.

[0055] Combined with Figures 9-11 As shown in the figure, the present invention provides an automated method for tying rings on metal sheets, and the steps are as follows:

[0056] S1. Prepare the metal sheet and iron wire: The metal sheet is conveyed into the material distribution seat 12 through the vibrating disk 5. The material distribution seat 12 moves the metal sheet to the picking end of the cam manipulator 13 one by one. The iron wire in the wire reel 21 is conveyed to the wire threading tube 23 through the roller group 22. One end of the wire threading tube 23 passes through the material blocking plate 15 and moves to the material blocking fixture 14.

[0057] S2. Thread the metal sheet and stack: The cam manipulator 13 places the metal sheet above the material blocking fixture 14 one by one. The material blocking fixture 14 performs cyclic opening and closing actions. The wire threading tube 23 passes through the inner hole of the metal sheet, so that the metal sheets are stacked above the material blocking plate 15 one by one along the wire threading tube 23.

[0058] S3. Clamp the iron wire: After the metal sheet threading and stacking are completed, the feeding mechanism 1 stops working, and the cam manipulator 13 and the material blocking fixture 14 move away from the wire threading tube 23. The moving frame 41 approaches the workbench 6, and controls the wire clamping manipulator 44 to move to the upper and lower ends of the wire threading tube 23. The upper wire clamping manipulator 44 clamps the iron wire. The wire threading tube 23 moves downward through the lifting seat 24 and gets out of the grasping range of the wire clamping manipulator 44. The lower wire clamping manipulator 44 clamps the iron wire.

[0059] S4. Cut the iron wire: The cutting seats 25 on both sides of the iron wire move towards each other and then reset, so that the iron wire is cut off. The distance between the two groups of wire clamping manipulators 44 is less than the length of the wire threading tube 23. During the movement of the wire threading tube 23, the iron wire is always inside the wire threading tube 23.

[0060] S5. Shape the iron wire: The moving seat moves away from the workbench 6, and takes out the iron wire with the metal sheet through the wire clamping manipulator 44. The feeding mechanism 1 changes its state to S1. Rotate the steering plate 42 so that the iron wire is parallel to the ground. Control the rotating seats 43 to move towards each other. The two groups of wire clamping manipulators 44 approach and make the two ends of the iron wire cross.

[0061] S6. Form the wire loop: The moving frame 41 approaches the wire loop forming mechanism 3, and places the two ends of the iron wire at the locking fixture 31. The locking fixture 31 clamps the two ends of the iron wire. The wire loop motor 32 rotates the connection part of the two ends of the iron wire into a twist shape to form a metal sheet group.

[0062] S7. Unload the metal sheet group: The wire clamping manipulator 44 releases the iron wire. After the moving frame 41 moves away from the wire loop forming mechanism 3, it resets and jumps to S3. The locking fixture 31 releases the iron wire. The metal sheet naturally falls onto the discharge track 33 and slides into the material box.

[0063] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
