Description

Technical Field

[0001] This utility model relates to the technical field of media disc production equipment, specifically to a media disc welding device with interchangeable upper and lower molds. Background Technology

[0002] Magnetic separation utilizes the difference in magnetic permeability of minerals. When minerals pass through a magnetic field, those with low magnetic permeability are not adsorbed, while those with high magnetic permeability are adsorbed by the medium disk and then fall off after losing magnetism, thus achieving mineral separation.

[0003] Currently, a dielectric disk typically consists of an upper layer of wire, a lower layer of wire, and a central bushing. The upper and lower layers of wire are welded together perpendicularly to the central bushing, with the ends of the lower layer of wire forming a circular outer contour. At present, there is no dedicated welding equipment for dielectric disks, so welding is often done manually. There are many welding positions on the dielectric disk, and the work is repetitive. In addition, the specifications and sizes of dielectric disks vary widely, and manual welding is not only inefficient but also cannot effectively guarantee the welding quality.

[0004] Therefore, developing and designing a medium disk welding equipment with interchangeable upper and lower molds that can improve welding efficiency and quality, reduce labor intensity, and is easy to operate is an urgent problem to be solved at present. Summary of the Invention

The robotic arm 6 automatically drives the welding gun according to a preset program to complete the welding process on one side of the medium disk; a controller is coupled to the lifting assembly, the robotic arm 6 and the welding gun respectively. The controller can control the switching and working intensity of the lifting assembly, the robotic arm 6 and the welding gun, thereby realizing the orderly operation of the cooperation process between the upper layer wire and the lower layer wire and the central shaft sleeve and the welding process.

[0035] For details, please refer to Figure 1 The bracket 1 is equipped with a material box 12, which is used to place the upper layer wires. Workers can easily place the upper layer wires on the upper positioning component.

[0036] It should be noted that the robotic arm 6 is preferably a six-axis robotic arm; the welding gun is preferably a laser welding gun; and the controller is preferably a PLC.

[0037] In this embodiment, please refer to Figure 1 and Figure 2The upper positioning component includes an upper placement plate 23. The bracket 1 is provided with an upper cover 11 at the position corresponding to the upper placement plate 23. The upper placement plate 23 can be detachably placed and positioned inside the upper cover 11, and the staff can easily remove the upper placement plate 23. Several horizontal positioning strips 21 are provided inside the upper placement plate 23. The shape and arrangement of the several horizontal positioning strips 21 are based on not affecting the lifting of the lower wire and the central shaft sleeve.

[0038] Further, please refer to Figure 2 The upper cover 11 has symmetrically arranged dovetail grooves inside. The upper placement plate 23 has dovetail blocks at both ends that match the dovetail grooves. The dovetail grooves can conveniently position the upper placement plate 23 and can also adapt to upper placement plates 23 of different specifications, making it easy to complete the welding of media disks of different sizes.

[0039] Furthermore, please refer to Figure 2 The upper placement plate 23 has a circular hole, and several horizontal positioning strips 21 are provided in the circular hole. The ends of the horizontal positioning strips 21 are flush, and the upper layer wire can be placed at the square-shaped limiting protrusions 22 at the ends of the horizontal positioning strips 21. The shape of the lifting platform 4 matches the circular hole. The lifting platform 4 supports the lower layer wire and the central shaft sleeve and extends into the circular hole from below. The lower layer wire and the central shaft sleeve extend into the circular hole and cooperate with the upper layer wire. Specifically, the specific shape and number of the limiting protrusions 22 are based on the ability to stably place the upper layer wire.

[0040] In this embodiment, please refer to Figure 1 and Figure 3 The lower positioning component includes a lower pull-out frame 32 and a lower placement plate. The lower pull-out frame 32 can move horizontally relative to the bracket 1. Several baffles 31 are provided inside the lower pull-out frame 32, and the lower placement plate can be placed on the several baffles 31. The lower wire and the central shaft sleeve are placed on the lower placement plate. Specifically, the several baffles 31 are distributed on at least two oppositely arranged sides of the lower pull-out frame 32 to ensure that the lower placement plate can be stably placed on the several baffles 31.

When the lower pull-out frame 32 is pulled out, the lower placement plate can be placed on the baffle 31, and then the lower pull-out frame 32 is pushed in. The lifting platform 4 rises to lift the lower layer wires and the central shaft sleeve on the lower placement plate. Specifically, the bracket 1 should be equipped with a limiting block to limit the pushing position of the lower pull-out frame 32, so that the lower pull-out frame 32 is pushed in accurately each time, thereby ensuring the precision of the lower layer wires and the central shaft sleeve in matching with the upper layer wires after they rise. At the same time, in order to ensure that the lower layer wires and the central shaft sleeve are stably placed on the baffle 31, one or more baffles 31 can also be correspondingly provided on the bracket 1 to support or limit the position of the lower placement plate when the lower pull-out frame 32 is pushed in.

[0042] In this embodiment, please refer to Figure 1 and Figure 4 The lifting component is preferably a scissor mechanism 5, which can drive the lifting platform 4 to rise and fall by extending and retracting the scissor mechanism 5; in other embodiments, the lifting component can also be a cylinder, an electric push rod or a linear stepper motor, as long as it can stably drive the lifting platform 4 to move in the vertical direction.

[0043] Further, please refer to Figure 4 The scissor mechanism 5 includes several cross-arranged connecting rods 51 and a servo motor 52. The output shaft of the servo motor 52 is connected to a connecting rod 51 through several gears 53 and a lead screw 54.

[0044] In this embodiment, please refer to Figure 1 and Figure 4 Preferably, there are two upper positioning components, two lower positioning components, and two lifting platforms 4. The robotic arm 6 is located between the two upper positioning components. After the welding of one side of the medium disk is completed, the worker can remove the upper positioning component and flip it over to place it on another upper positioning component. The robotic arm 6 can drive the welding gun to complete the welding of the other side of the medium disk. This can effectively improve the processing efficiency per unit time by 2-5 times, and the welding quality is more reliable.

[0045] Please refer to Figures 1-4 The specific usage process of this utility model is as follows:

[0046] Place the lower layer wire and the central shaft sleeve on the lower placement plate, then place the lower placement plate on several baffles 31 of the lower pull-out frame 32, and push the lower pull-out frame 32 in.

[0047] Place the upper positioning component into the dovetail groove of the upper cover 11, and then place the upper wire at the limiting protrusion 22 at the end of several horizontal positioning strips 21.

[0048] The lifting assembly drives the lifting platform 4 to move from the first height to the second height, lifting the placement plate and causing the lower layer wire and the central shaft sleeve to extend into the round hole of the upper placement plate 23 and cooperate with the upper layer wire.

[0049] The robotic arm 6 drives the laser welding gun to weld the front side of the medium disk according to the preset program. After the front side of the medium disk is welded, the upper positioning component is flipped and placed into the upper cover 11. The robotic arm 6 can automatically complete the welding of the back side of the medium disk by driving the laser welding gun.
