Technical Field

[0001] This invention relates to the field of low-voltage air switch manufacturing technology, and in particular to a workpiece supply system. Background Technology

[0002] The low-voltage air switch has a contact assembly, which includes a bracket, a moving contact, a trip bolt, and two positioning shafts mounted thereon. The moving contact is welded to one end of the bracket, one positioning shaft is used to hinge the bracket to the trip bolt, and the other positioning shaft is used to limit the range of rotation of the bracket.

[0003] Currently, the production of contact assemblies is done manually. The moving contact is welded to the bracket by hand with a welding torch, and then the bracket is placed into the trip bolt. The two are then assembled together by the positioning shaft. Since each process requires manual operation, the production efficiency of contact assemblies is low. Summary of the Invention

[0004] In view of this, the present invention proposes a workpiece supply system to automate the supply of moving contacts in the automated production process of contact assemblies. The workpiece supply system includes a conveying device, a transfer table, and a clamping device. The conveying device is used to orderly orient and convey workpieces to the transfer table, and the clamping device is used to remove workpieces from the transfer table and place them at a processing position. The transfer table is provided with a first guide groove and a second guide groove that are perpendicular to each other. The loading port of the first guide groove is connected to the discharge end of the conveying device, and a unloading area is formed at the intersection of the ends of the first and second guide grooves. The workpiece supply system further includes a first push plate and a first pushing mechanism, as well as a second push plate and a second pushing mechanism. The first pushing mechanism drives the first push plate to slide in the first guide groove, and the first push plate is used to push the workpiece at the loading port to the unloading area.

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the following embodiments are provided to further illustrate the present invention in detail.

[0042] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0043] Reference Figure 1 The strip b has been pre-cut at regular intervals to form supports a1, and multiple guide holes b1 are pre-formed on the strip b at set intervals. During the conveying process of the strip b, after each conveying cycle, other processing mechanisms at their respective workstations can perform cutting, welding, riveting, and assembly processes on the strip b, thereby processing it into a contact assembly. Figure 1 The final contact assembly includes a bracket a1, a moving contact a2, a trip bolt a3, and two positioning shafts a4 mounted thereon. The moving contact a2 is welded to one end of the bracket a1. One positioning shaft a4 is used to hinge the bracket a1 to the trip bolt a3, and the other positioning shaft a4 is used to limit the range of rotation of the bracket a1.

[0044] Reference Figure 2 In this automatic machine, a material belt b is supported on the feeding track 5. The material belt conveying system 91 pulls the material belt b at a fixed step distance. When the material belt b moves forward one step distance, two positioning mechanisms 94 simultaneously activate, inserting their guide pins into a guide hole b1 on the material belt b, preventing the material belt b from moving relative to the feeding track 5. Then, the workpiece supply system places a moving contact a2 on the material belt b, and the welding device 6 welds the moving contact a2 to a bracket a1. Additionally, the cutting mechanism 4 cuts off the excess portion of the material belt b corresponding to the previous bracket a1. It should be noted that the "step distance" mentioned in this embodiment is consistent with the pre-cut spacing between adjacent brackets a1 on the material belt b. This "step distance" can be adjusted according to the actual spacing between adjacent brackets a1 and is not interpreted as a specific numerical value.

[0045] This embodiment proposes a workpiece supply system to automate the supply of moving contacts during the automated production process of contact assemblies.

[0046] exist Figure 2As can be seen, the workpiece supply system includes a conveying device 1, a transfer table 2, and a clamping device 3. The conveying device 1 is used to arrange and transport the workpieces in an orderly manner to the transfer table 2, and the clamping device 3 is used to remove the workpieces from the transfer table 2 and place them at the processing position. It should be noted that although this embodiment uses the workpiece supply system as an example to supply the moving contact a2, the application of the workpiece supply system in this embodiment is not limited to this, and it can also be used to convey and supply other similar rod-shaped workpieces.

[0047] Reference Figure 3 The conveying device 1 includes a vibratory feeder 11 and a linear vibrating track 12. The vibratory feeder 11 includes a hopper 111 and a first vibrator 112 that drives the hopper 111 to vibrate. A spiral track 1111 is formed on the inner wall of the hopper 111. The linear vibrating track 12 is configured to vibrate under the drive of the second vibrator 121, and its feed end is located at the outlet of the vibratory feeder 11, while its discharge end extends to the feed port 2011 of the first guide trough 201.

[0048] For example, after a batch of moving contacts a2 are placed in the hopper 111 of the vibratory feeder 11, when the first vibrator 112 vibrates, each moving contact a2 can be sequentially oriented and enter the bottom end of the spiral track 1111, and move upward along the spiral track 1111. When the moving contacts a2 move to the outlet of the vibratory feeder 11, they are then transported to the transfer table 2 by the straight vibration track 12.

[0049] In a preferred embodiment, continue to refer to Figure 3 The conveying device 1 may also include a frequency converter, which is configured to control the vibration frequency of the first vibrator 112 and the second vibrator 121, so that the conveying device 1 can be adjusted according to different types of workpieces, and finally realize the function of supplying and conveying workpieces.

[0050] In a preferred embodiment, continue to refer to Figure 3 The conveying device 1 also includes a first support 113 for supporting the vibratory feeder 11 and adjusting its height, and a second support 122 for supporting the linear vibrating track 12 and adjusting its height. Thus, both the vibratory feeder 11 and the linear vibrating track 12 of the conveying device 1 can be adjusted according to the height of the transfer table 2.

[0051] In a preferred embodiment, refer to Figure 4 and Figure 5The transfer table 2 is provided with a first guide groove 201 and a second guide groove 202 that are perpendicular to each other. The loading port 2011 of the first guide groove 201 is connected to the discharge end of the conveying device 1, and a unloading area 203 is formed at the intersection of the ends of the first guide groove 201 and the second guide groove 202. The workpiece supply system also includes a first push plate 211 and a first pushing mechanism 21, as well as a second push plate 221 and a second pushing mechanism. The first pushing mechanism 21 drives the first push plate 211 to slide in the first guide groove 201, and the first push plate 211 is used to push the workpiece at the loading port 2011 to the unloading area 203. The second pushing mechanism drives the second push plate 221 to slide in the second guide groove 202, and the second push plate 221 is used to push the workpiece located in the unloading area 203 to the plane position for the clamping device 3 to pick up the workpiece.

[0052] In the workpiece supply system provided in this embodiment, the workpiece can be the moving contact a2 in the contact assembly. After the conveying device 1 arranges the workpiece in an orderly manner and conveys it to the transfer table 2, the first pushing mechanism 21 pushes the workpiece from the loading port 2011 to the unloading area 203 to achieve position adjustment of the workpiece along the direction of the first guide groove 201. Then, the second pushing mechanism further pushes the workpiece to the plane position for the clamping device 3 to pick up the workpiece to achieve position adjustment of the workpiece along the direction of the second guide groove 202. Finally, the clamping device 3 removes the workpiece from the transfer table 2 and places it in the designated processing position. In this way, by pushing the workpiece to a precise plane position, the accuracy of the automated process of supplying the moving contact a2 is improved.

[0053] It should be noted that the above-mentioned workpiece supply system may also include a controller, which is signal-connected to the conveying device 1, the clamping device 3, the first pushing mechanism 21, and the second pushing mechanism to achieve coordinated control of the workpiece supply system.

[0054] In a preferred embodiment, the workpiece supply system further includes a workpiece detector configured to detect whether a workpiece is present at the loading port 2011. For example, the workpiece detector can be a photoelectric switch configured to activate when a workpiece is present at the loading port 2011. Thus, the photoelectric switch can send its electrical signal to a controller, which then controls the first pushing mechanism 21 and its operation. Alternatively, the workpiece detector can also be an ultrasonic sensor.

[0055] Reference Figure 4The first pushing mechanism 21 can be a cylinder. Alternatively, the first pushing mechanism 21 can be a motor-driven screw and nut mechanism. The second pushing mechanism includes a guide rod 222, a slide rail 241, a slider 242, a lifting mechanism 24, and a moving plate 243. For example, the lifting mechanism 24 can be a cylinder. The guide rod 222 is connected to the second push plate 221 and extends parallel to the first guide groove 201. The slide rail 241 is arranged vertically, and the slider 242 is slidably disposed on the slide rail 241. The lifting mechanism 24 drives the slider 242 to slide on the slide rail 241. The moving plate 243 is connected to the slider 242, and the moving plate 243 has an inclined groove 2431 on the side facing the guide rod 222 for the guide rod 222 to be inserted. When the lifting mechanism 24 drives the slider 242 to rise, the second push plate 221 moves towards the unloading area 203 based on the cooperation between the inclined groove 2431 of the moving plate 243 and the guide rod 222. It should be noted that the second pushing mechanism in this embodiment can also be implemented in other ways, such as a cylinder connected to the transfer table 2, or a screw and nut mechanism driven by a motor.

[0056] Preferably, a long slot 22 extending along the length direction is provided on the side wall of the second guide groove 202, which allows the guide rod 222 to extend out and restricts the movement direction of the guide rod 222. Alternatively, if a limiting structure is provided between the second push plate 221 and the second guide groove 202, the second push plate 221 can only move in the direction extending along the second guide groove 202, and the long slot 22 may not be provided on the side wall of the second guide groove 202.

[0057] In a preferred embodiment, the transfer table 2 is provided with a third guide groove perpendicular to the plane position; the supply system also includes a third push plate 231 and a push rod 23. The third push plate 231 is slidably disposed in the third guide groove, and is used to push the workpiece located on its top surface to the height position for the clamping device 3 to pick up the material. The push rod 23 is connected between the slider 242 and the third push plate 231, so that the third push plate 231 is also driven by the lifting mechanism 24.

[0058] For example, the first pusher plate 211 and the second pusher plate 221 in the aforementioned embodiments realize the position adjustment of the moving contact a2 on the plane of the transfer table 2. In this embodiment, the third pusher plate 231 is used to further adjust the position of the moving contact a2 in the vertical direction, which further improves the accuracy of the automated process of supplying the moving contact a2. At the same time, the second pusher plate 221 and the third pusher plate 231 are driven by a lifting mechanism 24, which not only saves costs, but also facilitates the simultaneous adjustment of the moving contact a2 in the horizontal and vertical directions, saving time and improving the efficiency of the supply and conveying of the moving contact a2.

[0059] In a preferred embodiment, the gripping device 3 includes a mechanical claw 31 and a translation mechanism 32. The mechanical claw 31 is driven and opens and closes by a first drive mechanism. For example, the first drive mechanism can be a cylinder. The translation mechanism 32 is equipped with the mechanical claw 31 and can drive the mechanical claw 31 to move in a direction parallel to the extension direction of the first guide groove 201 and the extension direction of the second guide groove 202.

[0060] For example, combined Figure 5 The translation mechanism 32 includes a second drive device 321 and a third drive device 322. The second drive device 321 drives a moving block 3211 to move parallel to the first guide groove 201, and the moving block 3211 is equipped with a mechanical gripper 31. The third drive device 322 drives a moving stage 3221 to move parallel to the second guide groove 202, and the moving stage 3221 is equipped with the second drive device 321. The second drive device 321 can be selected as a screw-nut transmission mechanism driven by a motor, and the third drive device 322 can be selected as a cylinder.

[0061] In one embodiment of the gripping device 3, when the moving contact a2 is in a planar or vertical position for the gripping device 3 to pick up material, the third drive device 322 actuates, causing the mechanical gripper 31 to reach the gripping position. After the mechanical gripper 31 clamps the moving contact a2, the second drive device 321 actuates, causing the mechanical gripper 31 to reach the processing position above the material strip b. Then, the mechanical gripper 31 releases, placing the moving contact a2 at the welding position of the bracket a1. Next, the third drive device 322 actuates, causing the mechanical gripper 31 to move a distance along the material strip b relative to the placed moving contact a2. Further, the second drive device 321 actuates, causing the mechanical gripper 31 to return to its original position and await the next gripping task.

[0062] It should be noted that when the first pushing mechanism 21, the second pushing mechanism, the first driving mechanism, and the third driving device 322 are selected as cylinders, the cylinder can have a non-magnetic cylinder barrel and a non-magnetic piston, with a permanent magnetic ring on the piston. A magnetic switch is placed on the outside of the cylinder barrel, and when the piston moves to the desired stop position, the two springs of the magnetic switch are magnetized and attract each other, causing the contacts to close, thus changing the second magnetic switch from open to closed. A solenoid valve assembly can be connected to the air circuit of the cylinder to control the movement of the piston. By connecting the magnetic switch and the solenoid valve assembly to the controller signal, the controller can achieve coordinated control of the workpiece supply system.

[0063] This invention relates to the field of low-voltage air switch manufacturing technology, and in particular to a workpiece supply system. The workpiece supply system includes a conveying device 1, a transfer table 2, and a clamping device 3. The conveying device 1 is used to orderly and orient the workpieces and convey them to the transfer table 2, and the clamping device 3 is used to remove the workpieces from the transfer table 2 and place them in a processing position. Specifically, a first pushing mechanism 21 pushes the workpiece from the loading port 2011 to the unloading area 203, and a second pushing mechanism pushes the workpiece to a planar position for the clamping device 3 to pick it up. This achieves precise adjustment of the workpiece's planar position on the worktable, which is beneficial for the reliable gripping of the clamping device 3. The workpiece can be the moving contact a2 in the contact assembly, which improves the accuracy of the automated process of supplying the moving contact a2.
