Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment for coiled material strips, in particular to a dual-motor driven material strip tensioning and adjusting device for the coiled material strips. Background Art

[0002] In order to facilitate batch processing of conductive terminals, the conductive terminals are designed to be arranged in parallel in the shape of long strips. At the same time, in order to facilitate transportation and automated processing, the long strips of raw materials are rolled up to form coils. However, in the automated processing process, since the coils are processed at a uniform speed, in order to ensure the uniform speed and constant tension of the coils, a tensioning device needs to be installed to maintain the uniform speed supply of the coils.

[0003] However, in actual applications, it is found that although the existing tensioning device on the market can adjust the tensioning force during the feeding of the material belt, the intervention and adjustment of the tensioning force will affect the material feeding speed, making it difficult to maintain the uniform feeding speed. If the uniform feeding speed is pursued, the intervention of the tensioning force will inevitably be weakened, which will lead to tension fluctuations. In severe cases, it may even cause the material belt to break, and the defects are obvious. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a dual-motor driven material strip tensioning adjustment device, which greatly improves the intervention control of the material strip tensioning force while ensuring uniform feeding speed, and effectively improves the supply problem of uniform speed and constant tension of the coiled material.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a dual-motor driven material belt tensioning and adjusting device, comprising a base plate, a main vertical plate vertically fixed to the base plate, and a feed rack and a discharging rack located on both sides of the main vertical plate; the main vertical plate is movably equipped with a floating rack, at least two floating wheel groups installed on the floating rack, and a lifting mechanism for driving the floating rack to move up and down; the feed rack is equipped with a driving wheel group and a stepping motor for driving the driving wheel group to rotate; the discharging rack is equipped with a driven wheel group; and a track changing device is provided below the driving wheel group, the floating wheel group and the driven wheel group.

[0006] Preferably, there are two floating wheel groups, and the two floating wheel groups are respectively arranged at two ends of the floating frame.

[0007] Preferably, the floating wheel group includes three rotating wheels arranged in parallel, the track-changing device includes two track-changing wheels arranged obliquely, and the angle between the rotation center axis of the track-changing wheel and the rotation center axis of the rotating wheel is 40 to 60 degrees.

[0008] Preferably, the lifting mechanism includes a synchronous wheel installed on the top of the main vertical plate, a synchronous belt wound around the synchronous wheel and a torque motor for driving the synchronous wheel to rotate, and the floating frame is fixedly connected to the synchronous belt.

[0009] Preferably, the driving wheel group includes two rotating wheels arranged in parallel, a track-changing wheel is provided below the driving wheel group, and the angle between the rotation center axis of the track-changing wheel and the rotation center axis of the rotating wheel is 40 to 60 degrees.

[0010] Preferably, the lifting mechanism further comprises a sliding rod arranged parallel to the main vertical plate and a sliding sleeve movably connected to the sliding rod, and the floating frame is fixed to the sliding sleeve.

[0011] Preferably, a pressure wheel is provided above the rotating wheel and is pressed tightly against the rotating wheel.

[0012] The beneficial effects of the present invention are as follows: the present invention provides a dual-motor driven material belt tensioning and adjusting device. In actual application, the material belt first enters from the driving wheel group on the first-level frame, bypasses the driving wheel group, and then enters the two floating wheel groups in sequence. After the material belt is wound multiple times by the two floating wheel groups and the two track-changing devices, it is wound out from the driven wheel group on the discharging frame. The wound material belt is pulled into the electroplating process by the traction device in the electroplating equipment for electroplating. The present invention utilizes the driving wheel group to accurately control the feeding speed of the material belt, thereby achieving the purpose of uniform feeding. The multiple windings of the material belt by the two floating wheel groups and the two track-changing devices can effectively increase the friction between the material belt and the rotating wheel and the track-changing wheel, ensuring that the material belt and each wheel group will not slip, thereby improving the reliability of the tensioning and adjusting device. During the uniform feeding of the strip, if the strip tension becomes too loose, the floating wheel assembly, driven by the lifting mechanism, moves upward. Due to the sufficient travel of the floating wheel assembly, there is ample space to tighten the slack strip to the appropriate tension range, preventing the tension from affecting the strip feed speed. If the strip tension becomes too tight, the floating wheel assembly, driven by the lifting mechanism, moves downward, releasing the strip tension while continuously feeding the strip wound between the two floating wheel assemblies and the two track-changing devices to the electroplating equipment. This eliminates the need to accelerate the driving wheel assembly, which would cause the strip to suddenly accelerate and then decelerate, resulting in instantaneous strip accumulation. This system offers high stability and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the embodiments. The contents mentioned in the embodiments are not intended to limit the present invention.

[0017] like Figures 1 to 3 As shown, a dual-motor driven material belt tensioning and adjusting device includes a base plate, a main vertical plate 1 vertically fixed to the base plate, and a feed frame 2 and a discharging frame 3 located on both sides of the main vertical plate 1. The main vertical plate 1 is movably equipped with a floating frame 4, at least two floating wheel groups 5 installed on the floating frame 4, and a lifting mechanism for driving the floating frame 4 to move up and down. The feed frame 2 is equipped with a driving wheel group 6 and a stepping motor 7 for driving the driving wheel group 6 to rotate. The discharging frame 3 is equipped with a driven wheel group 8. A track changing device 9 is provided below the driving wheel group 6, the floating wheel group 5 and the driven wheel group 8.

[0018] In this embodiment, there are two floating wheel assemblies 5, each disposed at the two ends of the floating frame 4. The floating wheel assemblies 5 include three parallel rotating wheels 10. The main vertical plate 1 is designed to be sufficiently high to allow for a relatively large travel range for the floating wheel assemblies 5. Generally, the top of the main vertical plate 1 is slightly lower than the safe height of the workshop. In actual use, the material strip first enters the first-stage frame from the driving wheel assembly 6, bypasses the driving wheel assembly 6, and then enters the two floating wheel assemblies 5 in sequence. After multiple windings through the two floating wheel assemblies 5 and two track-changing devices 9, the material strip is wound out from the driven wheel assembly 8 on the discharge frame 3. The wound material strip is then pulled by a traction device within the electroplating equipment and taken into the electroplating process for electroplating. The present utility model utilizes the driving wheel assembly 6 to precisely control the feed speed of the material strip, achieving uniform feeding speed. The multiple windings of the material strip through the two floating wheel groups 5 and the two track-changing devices 9 can effectively increase the friction between the material strip and the rotating wheel 10 and the track-changing wheel 11, ensuring that the material strip will not slip between the various wheel groups and improving the reliability of the tensioning adjustment device. During the uniform feeding process of the material strip, when the material strip tension is too loose, the floating wheel group 5 moves upward under the drive of the lifting mechanism. Since the stroke of the floating wheel group 5 is large enough, there is enough space to tighten the loose material strip to the appropriate tension range, and it can also prevent the material strip from being affected by the tightening of the tension force and affecting the feeding speed of the material strip. When the material strip tension is too tight, the floating wheel group 5 moves downward under the drive of the lifting mechanism, while releasing the material strip tension, and continuously supplies the material strip wound between the two floating wheel groups 5 and the two track-changing devices 9 to the electroplating processing equipment, without accelerating the driving wheel group 6, causing the material strip roll to suddenly accelerate and then decelerate, causing the material strip to accumulate instantly. It has high stability and strong practicality.

[0019] In this embodiment, the lifting mechanism comprises a synchronous pulley 12 mounted on the top of the main vertical plate 1, a synchronous belt 13 wound around the synchronous pulley 12, and a torque motor 14 for driving the synchronous pulley 12. The floating frame 4 is fixedly connected to the synchronous belt 13. The torque motor 14 monitors the downward force exerted by the floating frame 4 on the synchronous belt 13 and synchronous pulley 12 in real time, thereby enabling monitoring and adjustment of the web tension. This mechanism offers the advantages of a simple structure, fast adjustment response, and wide adjustment tolerance.

[0020] In this embodiment, the lifting mechanism also includes a sliding rod 16 arranged parallel to the main vertical plate 1 and a sliding sleeve movably connected to the sliding rod 16. The floating frame 4 is fixed to the sliding sleeve. The floating frame 4 moves up and down along the sliding rod 16 following the sliding sleeve to avoid the floating frame 4 shaking and affecting the adjustment of the tensioning force, and has higher stability.

[0021] In this embodiment, the track-changing device 9 includes two track-changing wheels 11 arranged obliquely, and the angle between the rotation center axis of the track-changing wheel 11 and the rotation center axis of the rotating wheel 10 is 40 to 60 degrees. After the material belt is wound around one rotating wheel 10, it is first wound around from one side of the track-changing wheel 11, and then wound out from the other side of the track-changing wheel 11 and wound around from the other rotating wheel 10, thereby realizing the track-changing transition of the material belt by the track-changing wheel 11, and realizing the multiple winding of the material belt through the two floating wheel groups 5 and the two track-changing devices 9, which greatly increases the winding length of the material belt in the tensioning device, increases the pre-stored length of the material belt in the tensioning device, improves the influence of the tensioning device on the material belt feeding speed during tensioning adjustment, enhances the friction between the material belt and the tensioning device, avoids the material belt slipping, improves the precision control of the feeding speed, and is highly practical.

[0022] In this embodiment, the driving wheel group 6 includes two rotating wheels 10 arranged in parallel, and a track-changing wheel 11 is arranged below the driving wheel group 6. The angle between the rotation center axis of the track-changing wheel 11 and the rotation center axis of the rotating wheel 10 is 40 to 60 degrees. Similar to the above content, the contact area between the material belt and the rotating wheel 10 and the track-changing wheel 11 is increased when the material belt enters the driving wheel group 6, and it is also convenient for the material belt to move in the direction when it is wound out of the driving wheel group 6, so that the material belt can more conveniently enter the floating wheel group 5 and the track-changing device 9 for winding after winding out of the driving wheel group 6, and has strong operability.

[0023] In this embodiment, a belt pressing roller 15 is provided above the rotating wheel 10 and is tightly pressed against the rotating wheel 10 , thereby further strengthening the friction between the material belt and the driving wheel and improving reliability.
