Description

Technical Field

[0001] This utility model relates to a constant tension adjustment device for wire and an electroplating equipment, belonging to the technical field of electroplating wire feeding equipment. Background Technology

[0002] Among the various types of electroplating equipment, those involving wire feeding play a crucial role. For example, in electroplating of wires and cables, and leads for electronic components, the wire, as the substrate to be plated, needs to be stably and evenly drawn from the feeding device and fed into the electroplating tank for processing. Traditional wire feeding systems in electroplating equipment typically employ simple mechanical structures, such as tension springs and rollers, to control the wire tension. However, traditional tension control devices struggle to compensate effectively and promptly, leading to frequent instances of uneven tension.

[0003] Currently, although there have been some technological improvements in tension control in the field of electroplating equipment, existing technologies still have many shortcomings. While some improved technologies can enhance the stability of tension control to a certain extent, they are often complex in structure and expensive, making them difficult to widely apply in small and medium-sized electroplating enterprises. Moreover, in electroplating production, the wire is mostly fed vertically upwards, making it impossible to stably control the feeding tension, resulting in uneven electroplating layer thickness and affecting the electroplating quality of the product. Utility Model Content

[0033] like Figures 1 to 5 As shown, this application provides a constant tension adjusting device for wires. It has a simple structure and can stably control the tension of the wire during feeding, resulting in a more uniform thickness of the electroplated layer and improved quality of the electroplated product. The constant tension adjusting device includes an eccentric wheel 1, a first crossbar 2, a second crossbar 3, a connecting piece 4, a brake assembly 5, and a roller 7. The eccentric wheel 1 is located at one end of the first crossbar 2 and connected to it. The roller 7 is installed at the end of the first crossbar 2 opposite to the eccentric wheel 1. The eccentric wheel 1 has a first hole 11 and is connected to the electroplating equipment via a pin or bolt. The eccentric wheel 1 and the first crossbar 2 can rotate around the center of the first hole 11. The second crossbar 3 is located on one side of the first crossbar 2, and both are on the same plane. The second crossbar 3 has a second hole 31 and is connected to the electroplating equipment via a pin or bolt. The second crossbar 3 can rotate around the center of the second hole 31. One end of the second crossbar 3 abuts against the eccentric wheel 1, and two rollers 7 are provided at the end of the second crossbar 3 opposite to the eccentric wheel 1. The second crossbar 3 is connected to the brake assembly 5 through the connector 4. The tension of the thread 9 can be adjusted by closing or opening the brake assembly 5.

[0034] In some embodiments, the adjusting device further includes a material tray 6 and a shaft 8. The material tray 6 is sleeved on the outer periphery of the shaft 8 and fixedly connected to the shaft 8. The wire 9 is wound on the material tray 6. The material tray 6 can rotate with the shaft 8 to release the wire 9. The wire 9 released by the material tray 6 passes through the rollers 7 on the second crossbar 3 and the first crossbar 2 in sequence, and then enters the electroplating equipment. The wire 9 is released by winding on the rollers 7. The surface of the rollers 7 is smooth and flat, avoiding the problem of scratching or damaging the wire.

[0035] In some embodiments, the brake assembly 5 includes a friction wheel 51 and a brake ring 52. The friction wheel 51 is sleeved on the outer periphery of the shaft 8 and can rotate with the shaft 8. The brake ring 52 has a semi-circular ring structure, with one end connected to the connector 4. The brake ring 52 can abut against the friction wheel 51. The material tray 6 rotates to release the wire 9. When the tension on the wire 9 is small, the constraint force of the wire 9 on the rollers 7 on the first crossbar 2 and the second crossbar 3 becomes smaller. The first crossbar 2 rotates counterclockwise around the center of the eccentric wheel 1, making the angle between the first crossbar 2 and the second crossbar 3 larger. At this time, the position with the smaller radius of the eccentric wheel 1 abuts against the second crossbar 3. The second crossbar 3 rotates clockwise around the center of the second hole 31, and the connector 4 drives the brake ring 52 to move upward, so that the brake ring 52 abuts against the friction wheel 51. Through the friction of the brake ring 52 against the friction wheel 51, the shaft 8 is decelerated, thereby reducing the wire feeding speed of the material tray 6 and increasing the tension on the wire 9. When the tension on the wire 9 is large, the constraint force of the wire 9 on the rollers 7 on the first crossbar 2 and the second crossbar 3 increases. Under the influence of the constraint force of the wire 9, the first crossbar 2 rotates clockwise around the rotation center of the eccentric wheel 1. The radius at the contact position between the eccentric wheel 1 and the second crossbar 3 increases. Under the pressure of the eccentric wheel 1, the second crossbar 3 also rotates counterclockwise, causing the connecting piece 4 and the brake ring 52 to move downward, so that the brake ring 52 separates from the friction wheel 51, or reduces the friction between the two, so that the rotation speed of the shaft 8 increases, thereby increasing the wire feeding speed of the feed tray 6 and reducing the tension on the wire 9.

[0036] Furthermore, in this embodiment, the larger the angle between the first crossbar 2 and the second crossbar 3, the higher the position of the connecting piece 4, the greater the friction between the brake ring 52 and the friction wheel 51, the lower the rotational speed of the shaft 8, and the slower the wire feeding speed of the tray 6. Conversely, the smaller the angle between the first crossbar 2 and the second crossbar 3, the lower the position of the connecting piece 4, the smaller the friction between the brake ring 52 and the friction wheel 51, or the two may separate, resulting in no friction between the friction wheel 51 and the brake ring 52, increasing the rotational speed of the shaft 8, thereby accelerating the wire feeding speed of the tray 6. This adjustment device has a simple and compact structure, a wide range of applications, and good stability. It can automatically adjust the wire feeding speed of the tray 6 according to the tension of the wire 9. Through this adjustment device, the wire 9 can be fed in a self-feedback manner, ensuring that the wire 9 always receives constant tension at different speeds, meeting the wire feeding requirements of electroplating products at different speeds.

[0037] Optionally, the connecting member 4 can be a connecting rod or a spring, and the connecting member 4 and the second crossbar 3 can be connected by a pin.

[0038] Alternatively, the brake ring 52 can also be a ring structure, as long as it can be ensured that the brake ring 52 can abut against the friction wheel 51 under the drive of the connector 4.

[0039] Furthermore, this application also provides an electroplating apparatus using the aforementioned wire constant tension adjusting device. This device is connected to the electroplating apparatus via a shaft 8. Wires 9 wound on a tray 6 are conveyed into the electroplating apparatus via rollers 7 and come into uniform contact with the electroplating solution, resulting in a more uniform film thickness and improved product quality. Because the electroplating apparatus uses any of the aforementioned wire constant tension adjusting devices, it possesses the advantages described above.

[0040] 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.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
