Description

Technical Field

[0001] The present application relates to the technical field of material strip recycling, and in particular to a material strip drive recycling device. Background Art

[0002] At present, the ACF (Anisotropic Conductive Film) tape is collected by using a pinch wheel to pinch the tape, and the stepper motor drives the pinch wheel to rotate, thereby pulling the tape. Since the ACF tape is in a state of bending and deformation when it is pressed and rotated, the force on each part of the tape is uneven during the transmission process. The bending deformation will introduce additional stress, which will interfere with the normal driving of the tape. The ACF tape is easy to swing on the pinch wheel, making it difficult to transmit it according to the precise path and speed, resulting in unstable driving and low precision.

For example, by accurately controlling the drive assembly, it can be ensured that the distance that the movable clamping assembly advances each time is consistent, so that the material belt is pulled out stably without the situation of speed fluctuations or left and right shaking. The material belt recovery mechanism is located downstream of the material belt drive mechanism and is used to collect the material belt. After the material belt is pulled out by the movable clamping assembly and clamped by the fixed clamping assembly, the material belt recovery mechanism collects the material belt in an orderly manner. This process further stabilizes the transmission path of the material belt and avoids the shaking of the material belt during the recovery process due to lack of effective guidance and sorting. The material belt recovery mechanism can reasonably adjust the collection method and rhythm according to the characteristics of the material belt and the pulling speed, so that the material belt can smoothly transition from the driving mechanism to the recovery mechanism, reducing the unstable factors in the entire material pulling and recovery process, thereby effectively solving the problem of unstable and shaking material pulling, and improving the accuracy and stability of material belt pulling and recovery.

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0026] Please refer to FIG1 . An embodiment of the present application provides a material belt drive recovery device 100. The material belt drive recovery device 100 includes a support component 1, a material belt drive mechanism 2, and a material belt recovery mechanism 3. Please refer to FIG2 and FIG3 . The material belt drive mechanism 2 includes a movable clamping component 21, a driving component 22, and a fixed clamping component 23. The driving component 22 and the fixed clamping component 23 are both arranged on the support component 1. The driving component 22 is driven and connected to the movable clamping component 21. The movable clamping component 21 and the fixed clamping component 23 are both used to clamp or loosen the material belt. The driving component 22 is used to drive the movable clamping component 21 to move forward or backward along the material pulling direction. The material belt recovery mechanism 3 is arranged on the support component 1. The material belt recovery mechanism 3 is located downstream of the material belt drive mechanism 2. The material belt recovery mechanism 3 is used to collect the material belt. The working principle of the material pulling and recovery of the above-mentioned material belt drive recovery device 100 is as follows: during the material pulling process, the movable clamping component 21 clamps the material belt, the fixed clamping component 23 loosens the material belt, and the driving component 22 drives the movable clamping component 21 to move forward in the material pulling direction, and the movable clamping component 21 pulls out a section of the material belt. Then, the fixed clamping component 23 clamps the material belt, the movable clamping component 21 loosens the pulled-out material belt, and the material belt recovery mechanism 3 collects the material belt pulled out by the movable clamping component 21. The above-mentioned material belt drive recovery device 100 changes the driving mode. The traditional pressing and rotating driving mode relies on the pressing wheel to press the material belt and pull the material belt by rotating, while the material belt drive recovery device 100 in the embodiment of the present application adopts the method of the movable clamping component 21 and the fixed clamping component 23 cooperating with the driving component 22. This clamping drive avoids the uneven stress caused by bending and deformation of the material belt during the pressing and rotating process. Because there is no continuous squeezing and bending deformation of the clamping wheel, the material strip can be pulled in a relatively more natural state, reducing the introduction of additional stress, so that the material strip always remains on the predetermined path during the driving process, reducing the possibility of the material strip running off track, thereby effectively reducing the possibility of unstable and shaking material pulling. The driving component 22 can accurately drive the movable clamping component 21 to move forward or backward in the pulling direction. When pulling the material, the movable clamping component 21 moves forward to pull out a section of the material strip, which is then clamped by the fixed clamping component 23, and the movable clamping component 21 is loosened. Furthermore, the material strip drive recovery device 100 in the embodiment of the present application can achieve precise material pulling control. This step-by-step driven and precisely controlled material pulling process is more stable than the continuous rotation pulling of the traditional compression and rotation drive method. The length and speed of each material pulling can be precisely controlled according to the preset program and parameters, so that the distance of each moving clamping assembly 21 moving forward and backward is consistent, so that the material strip can be pulled out stably without the situation of speed fluctuation or left and right shaking, avoiding the material pulling shaking caused by factors such as speed fluctuation and friction force change that may occur during the rotation drive process. The material strip recovery mechanism 3 is located downstream of the material strip driving mechanism 2 and is used to collect the material strip.After the material strip is pulled out by the movable clamping assembly 21 and clamped by the fixed clamping assembly 23, the material strip recovery mechanism 3 collects the material strip in an orderly manner. This process further stabilizes the transmission path of the material strip, allowing the material strip to smoothly transition from the driving mechanism to the recovery mechanism, and avoiding the shaking of the material strip during the recovery process due to lack of effective guidance and arrangement.

[0027] Furthermore, by providing the movable clamping assembly 21, the driving assembly 22 and the fixed clamping assembly 23, the material strip drive recovery device 100 can adapt to material strips of different types and specifications. By adjusting the clamping force and spacing of the clamping assembly, material strips of different widths, thicknesses and materials can be processed.

[0028] In an optional embodiment, the fixed clamping assembly 23 may be arranged upstream or downstream of the movable clamping assembly 21. It is understandable that when the fixed clamping assembly 23 is arranged upstream of the movable clamping assembly 21, the material belt first passes through the clamping space of the fixed clamping assembly 23, and then passes through the clamping space of the movable clamping assembly 21. When the fixed clamping assembly 23 is arranged downstream of the movable clamping assembly 21, the material belt first passes through the clamping space of the movable clamping assembly 21, and then passes through the clamping space of the fixed clamping assembly 23. Preferably, the fixed clamping assembly 23 is located upstream of the movable clamping assembly 21. Such an arrangement can stabilize the starting position of the material belt, avoid interfering with the activity of the movable clamping assembly 21, and facilitate the tension control of the material belt. Specifically, it can ensure that the material belt is at a preset path position in the initial stage, and prevent the material belt from shaking, deflecting, etc. before entering the movable clamping assembly 21. The main function of the movable clamping assembly 21 is to move forward or backward along the pulling direction to realize the pulling action. When the fixed clamping assembly 23 is upstream of the movable clamping assembly 21, the forward movement of the movable clamping assembly 21 in the material pulling direction will not be interfered by the fixed clamping assembly 23, which can ensure that the movable clamping assembly 21 can smoothly complete the material pulling action, making the material pulling process smoother and more efficient. The fixed clamping assembly 23 fixes the material belt upstream, so that the material belt has a relatively stable tension basis before entering the movable clamping assembly 21. During the material pulling process, the movable clamping assembly 21 can more accurately control the stretching degree of the material belt according to this initial tension state, preventing the material belt from breaking due to excessive tension or loosening due to insufficient tension, thereby ensuring the quality of the material belt and the stability of the entire production process.

[0029] Please refer to FIG3. In some embodiments, the movable clamping assembly 21 is located downstream of the fixed clamping assembly 23. The material belt driving mechanism 2 further includes a first guide 24 and a second guide 25 both provided on the support assembly 1. The first guide 24 is located upstream of the fixed clamping assembly 23. The second guide 25 is located downstream of the movable clamping assembly 21 and upstream of the material belt recovery mechanism 3. The first guide 24 is used to guide the material belt into the clamping space of the fixed clamping assembly 23. The second guide 25 is used to guide the material belt pulled out of the clamping space of the movable clamping assembly 21 into the material belt recovery mechanism 3. It can be understood that the material belt bypasses the first guide 24 and enters the clamping space of the fixed clamping assembly 23, and passes out of the clamping space of the fixed clamping assembly 23 and enters the clamping space of the movable clamping assembly 21. After passing out of the clamping space of the movable clamping assembly 21, the material belt is wound around the second guide 25. The second guide 25 guides the material belt into the material belt recovery mechanism 3. The first guide member 24 and the second guide member 25 can guide the material belt path and improve stability, and can optimize the material belt tension distribution so that the material belt has a suitable initial tension when entering the fixed clamping assembly 23 and passing through the movable clamping assembly 21, thereby preventing the material belt from being too loose or too tight.

[0030] In an optional embodiment, the first guide member 24 and the second guide member 25 may be guide rods or guide wheels. The first guide member 24 and the second guide member 25 may be rotatably connected to the support assembly 1 through bearings and / or rotating shafts. When the first guide member 24 and the second guide member 25 are both guide wheels, they may be rotatably connected to the support assembly 1 through the rotating shaft and the bearing. Specifically, the rotating shaft is fixed to the inner ring of the bearing, the outer ring of the bearing is fixed to the mounting hole of the support assembly 1, and the guide wheel is sleeved on the rotating shaft.

[0031] Please refer to FIG. 3. In some embodiments, the movable clamping assembly 21 includes a first driving member 211, a first clamping block 212 and a first back clamping plate 213. The first driving member 211 and the first back clamping plate 213 are both arranged on the driving member 22. The output end of the first driving member 211 is drivingly connected to the first clamping block 212. The first driving member 211 is used to drive the first clamping block 212 to move closer to or away from the first back clamping plate 213 to clamp or loosen the material strip. The first driving member 211 and the first back clamping plate 213 are both arranged on the driving member 22, so that the structure of the entire movable clamping assembly 21 is more compact. This compact structure is conducive to reducing the space occupied by the device. The cooperative work between the driving member 22 and the movable clamping assembly 21 is more direct and stable, reducing the vibration and displacement errors that may be generated due to the loose structure, thereby improving the accuracy and stability of the material strip pulling. The first driving member 211 is used to drive the first clamping block 212 to move closer to or away from the first back clamping plate 213 to achieve clamping or loosening of the material strip, and the clamping force can be dynamically and accurately controlled. Compared with structures with fixed clamping force such as spring clamps or pneumatic clamps, the first driving member 211 of the movable clamping assembly 21 of the embodiment of the present application can accurately adjust the position of the first clamping block 212 according to the material, thickness, tension, etc. of the material strip, thereby achieving fine adjustment of the clamping force and preventing the material strip from being pulled, damaged, or deformed.

[0032] In an optional embodiment, the first driving member 211 may be a telescopic motor or a telescopic cylinder.

[0033] Please refer to FIG. 3. In some embodiments, the fixed clamping assembly 23 includes a second driving member 231, a second clamping block 232, and a second back clamping plate 233. The second driving member 231 and the second back clamping plate 233 are both arranged on the supporting assembly 1. The output end of the second driving member 231 is drivingly connected to the second clamping block 232. The second driving member 231 is used to drive the second clamping block 232 to move closer to or away from the second back clamping plate 233 to clamp or loosen the material belt. By providing the second driving member 231, the second clamping block 232, and the second back clamping plate 233, flexible clamping force adjustment and precise position control can also be achieved, which can adapt to a variety of material belts and facilitate maintenance and troubleshooting.

[0034] In an optional embodiment, the second driving member may be a telescopic motor or a telescopic cylinder.

[0035] Please refer to FIG. 2. In some embodiments, the driving assembly 22 includes a third driving member 221, a screw rod 222 and a sleeve 223. The sleeve 223 is connected to the movable clamping assembly 21. The sleeve 223 is connected to the screw rod 222 by transmission. One end of the screw rod 222 is rotatably connected to the support assembly 1. The other end of the screw rod 222 is connected to the output end of the third driving member 221 by driving. The third driving member 221 is used to drive the movable clamping assembly 21 to advance or retreat along the material pulling direction through the screw rod 222 and the slide. The screw rod 222 transmission can achieve high-precision displacement control and a stable motion path, avoid the unstable movement of the movable clamping assembly 21 caused by the elastic deformation, relaxation or shaking of the belt or chain, and reduce the deviation of the material belt or uneven tension. The screw rod 222 has high mechanical efficiency and large load capacity. In the process of pulling materials, especially when the material belt is thicker, wider or has a higher tension, sufficient driving force is required to ensure that the movable clamping assembly 21 can smoothly pull the material belt. The screw rod 222 transmission can withstand a large axial force. The third driving member 221 transmits power to the sleeve 223 and the movable clamping assembly 21 through the screw rod 222, which can effectively overcome the resistance of the material belt, achieve a stable material pulling action, and reduce the stagnation or slippage of the material belt caused by insufficient driving force. The arrangement of the third driving member 221, the screw rod 222 and the sleeve 223 can be compactly arranged in space, miniaturized, and easy to integrate with the movable clamping assembly 21.

[0036] In an optional embodiment, the third driving member 221 may be a rotary motor or a rotary cylinder.

[0037] Please refer to Figures 2 and 3. In an optional embodiment, the driving assembly 22 further includes a first slide rail 224 and a first slide 225 that are slidably connected. The first slide rail 224 is fixed on the supporting assembly 1, and the first slide 225 is connected to the first driving member 211 and the first clamping block 212. Under the drive of the third driving member 221, the first driving member 211 and the first clamping block 212 in the movable clamping assembly 21 can move along the first slide rail 224 through the first slide 225, which can further improve the stability of the movable clamping assembly 21 during the forward and backward processes.

[0038] Please refer to Figure 4, the specific structure of the material belt recovery mechanism 3 will be introduced below: In some embodiments, the material belt recovery mechanism 3 includes a material belt buffer component 31 and a material belt recovery component 32, the material belt buffer component 31 is located downstream of the material belt driving mechanism 2, and the material belt recovery component 32 is located downstream of the material belt buffer component 31, the material belt buffer component 31 is used to guide and tighten the material belt pulled out by the movable clamping component 21, and the material belt recovery component 32 is used to collect the material belt. When the movable clamping component 21 pulls out a section of the material belt, the pulled material belt will be left outside and cause bending and deviation. The material belt buffer component 31 is set to restore the material belt to a tightened state to limit the moment the movable clamping component 21 pulls out the material belt, which can reduce the slack, swing and deviation of the material belt, thereby maintaining the material belt on the pulling path. The material tape buffer component 31 pre-processes the material tape upstream of the material tape recovery component 32, avoiding the problem of low recovery efficiency or poor recovery quality caused by poor material tape state (such as too loose, too tight or entangled), and passes the material tape to the material tape recovery component 32 in a good state. The material tape recovery component 32 performs the final collection work downstream, so that the material tape can be processed more efficiently.

[0039] In an optional embodiment, the material strip buffer device is located downstream of the second guide member 25, and the material strip guided out through the second guide member enters the material strip buffer device.

[0040] Please refer to Figure 4. In some embodiments, the material strip cache assembly 31 includes a third guide member 311, a fourth guide member 312 and a fifth guide member 313, which are all rotatably arranged on the support assembly 1. The fourth guide member 312 can be slidably connected to the support assembly 1 along the first direction. The third guide member 311 and the fifth guide member 313 are respectively arranged on both sides of the fourth guide member 312. The material strip is used to be simultaneously wound around the top of the third guide member 311, the bottom of the fourth guide member 312 and the top of the fifth guide member 313. The fourth guide member 312 is used to slide along the first direction toward the side away from the third guide member 311 and the fifth guide member 313 when the material strip is pulled out by the movable clamping assembly 21. The fourth guide member 312 is used to slide along the first direction toward the side close to the third guide member 311 and the fifth guide member 313 when the material strip recovery assembly 32 collects the material strip. By setting the third guide 311, the fourth guide 312 and the fifth guide 313, the tension of the material belt can be dynamically adjusted to adapt to the change of the pulling speed, stabilize the material belt transmission path, reduce the interference of the material belt with other components, and the structure is simple and easy to maintain. It can be understood that when the movable clamping assembly 21 pulls out the material belt, the fourth guide 312 moves along the first direction toward the side away from the third guide 311 and the fifth guide 313. This process makes the winding path of the material belt between the third, fourth and fifth guides 313 longer, so that the excess material belt can be stored, which plays a role of buffering. When the material belt recovery assembly 32 collects the material belt, the fourth guide 312 moves along the first direction toward the side close to the third guide 311 and the fifth guide 313, releases the stored material belt, ensures that the material belt always maintains appropriate tension, and enables the material belt to enter the recovery assembly smoothly. The pulling speed and recovery speed of the material belt may change due to factors such as the operating state of the equipment and the characteristics of the material belt. By moving the fourth guide 312 to cache and release the material belt, this speed change can be effectively adapted. For example, when the material pulling speed is accelerated instantly, the fourth guide 312 can quickly move away from the other two guides to increase the buffer capacity of the material belt; when the recovery speed is accelerated, the fourth guide 312 can approach the other guides in time to release enough material belts to ensure that the supply and recovery of the material belt can be balanced. The layout of the third guide 311, the fourth guide 312 and the fifth guide 313 provides a stable transmission path for the material belt. The material belt is wound around the specific positions of these three guides at the same time, so that the material belt has a clear direction and support point during the transmission process. This three-point support method is similar to a stable triangular structure, which can effectively prevent the material belt from deviating, shaking and other unstable phenomena during the transmission process. For example, in the case of high-speed material pulling, the material belt can be kept in the correct position due to the fixed path of these three guides, and can be smoothly transmitted from the material belt drive mechanism 2 to the material belt recovery component 32, thereby improving the working reliability of the entire device.

[0041] In an optional embodiment, the third guide member 311, the fourth guide member 312 and the fifth guide member 313 may be guide rods or guide wheels. The third guide member 311 and the fifth guide member 313 are arranged in a manner similar to the first guide member 24 and the second guide member 25, and are not described in detail here.

[0042] Please refer to FIG. 4 . In an optional embodiment, the fourth guide member 312 may be slidably connected to the support assembly 1 through the second slide rail 318 and the second slider 319. The second slide rail 318 is extended along the first direction and arranged on the support assembly 1, the fourth guide member 312 is arranged on the second slider 319, and the second slider 319 is slidably connected to the second slide rail 318. Alternatively, the fourth guide member 312 may be slidably connected to the support assembly 1 through a guide rod and a guide sleeve. The guide rod is extended along the first direction and arranged on the support assembly 1, the fourth guide member 312 is arranged on the guide sleeve, and the guide sleeve is slidably connected to the guide rod.

[0043] Please refer to FIG. 1 and FIG. 4 . In an optional embodiment, the third guide member 311 is located downstream of the second guide member 25 , and the pulled material strip transitions from the second guide member 25 to the third guide member 311 .

[0044] Please refer to FIG. 4. In some embodiments, the material strip buffer assembly 31 further includes a counterweight 314, which is connected to the fourth guide member 312. The counterweight 314 is used to pull the fourth guide member 312 to move in the first direction away from the third guide member 311 and the fifth guide member 313 when the material strip is pulled out. The counterweight 314 is connected to the fourth guide member 312. When the material strip is pulled out, the counterweight 314 uses its own gravity to pull the fourth guide member 312 to move in the first direction away from the third guide member 311 and the fifth guide member 313. When the material strip pulling speed changes, the counterweight 314 can automatically respond according to the change in the tension of the material strip. The counterweight 314 will move the fourth guide member 312 under the action of gravity, increase the buffer length of the material strip, thereby relieving the rapid increase of the material strip tension, keeping the material strip tension within a relatively stable range, and avoiding the material strip from breaking due to excessive tension.

[0045] Please refer to Figure 4. In some embodiments, the material strip cache assembly 31 also includes a sixth guide member 315, a seventh guide member 316 and a fourth driving member 317. The fourth driving member 317 is arranged on the support assembly 1. The output end of the fourth driving member 317 is drivingly connected to the seventh guide member 316. The fourth driving member 317 is used to drive the seventh guide member 316 to rotate. The sixth guide member 315 and the seventh guide member 316 are both rotatably connected to the support assembly 1. The sixth guide member 315 and the seventh guide member 316 are both located downstream of the fifth guide member 313 and upstream of the material strip recovery assembly 32. The sixth guide member 315 is frictionally connected to the seventh guide member 316 to convey the material strip transmitted through the fifth guide member 313. Since the fourth driving member 317 can drive the seventh guide member 316 to rotate, the rolling friction between the seventh guide member 316 and the sixth guide member 315 can make the material strip between the two move toward the direction of the material strip recovery assembly 32. Through the drive of the fourth driving member 317, the gravity of the fourth guide member 312 can be overcome, so that the material strip continues to move forward, and at the same time the fourth guide member 312 can be reset along the first direction.

[0046] Please refer to FIG. 4. In some embodiments, the material strip recovery component 32 includes a connected recovery cylinder 321 and a vacuum generator 322. The recovery cylinder 321 and the vacuum generator 322 are both arranged on the support component 1. The vacuum generator 322 is used to generate a vacuum in the recovery cylinder 321, and the recovery cylinder 321 is used to absorb the pulled-out material strip. The vacuum generator 322 generates a vacuum in the recovery cylinder 321. It is an efficient way to collect the material strip by using this vacuum adsorption force. When the material strip is pulled out, the vacuum environment in the recovery cylinder 321 will tightly adsorb the material strip on the cylinder wall. Compared with some traditional mechanical clamping or winding recovery methods, this adsorption collection is more efficient. When processing thin and soft material strips, mechanical clamping may cause deformation or damage of the material strip, while vacuum adsorption can act evenly on the surface of the material strip, ensuring that the material strip can be collected smoothly and the flatness of the material strip can be maintained. This method can achieve continuous collection of the material strip. As long as the vacuum generator 322 continues to work, the recovery drum 321 can continuously absorb the material tape, and there is no need to frequently adjust the winding position of the material tape or worry about uneven winding of the material tape as in winding-type recovery. This makes the material tape recovery process smoother and can improve the working efficiency of the entire device. It is especially suitable for production scenarios that require rapid recovery of a large number of material tapes. During the material tape recovery process, the recovery drum 321 provides a stable collection force through vacuum adsorption. This stable collection force can prevent the material tape from shaking, deflecting, and other unstable phenomena during the collection process. The material tape can fit tightly on the inner wall of the recovery drum 321, avoiding relative movement between the material tape and the recovery drum 321, thereby ensuring that the material tape can be collected neatly and improving the stability and reliability of the material tape recovery.

[0047] The working principle of the material belt drive recovery device 100 provided in the embodiment of the present application is described in detail below: the material belt is wound around the first guide 24, and then sequentially passed through the clamping space of the fixed clamping assembly 23 and the movable clamping assembly 21, and then passed through the second guide 25, and then sequentially wound around the top of the third guide 311, the bottom of the fourth guide 312, and the top of the fifth guide 313, and then enters between the sixth guide 315 and the seventh guide 316. First, the fixed clamping assembly 23 loosens the material belt, the movable clamping assembly 21 clamps the material belt, the driving assembly 22 drives the movable clamping assembly 21 forward to pull the material belt, and the fourth guide 312 descends under the action of the counterweight 314, so that the pulled-out material belt is cached between the third guide 311, the fourth guide 312, and the fifth guide 313. The fourth driving member 317 drives the seventh guide member 316 to rotate, so that the material to be collected moves toward the material strip recovery assembly 32 . The fourth guide member 312 slowly rises, and the recovery cylinder 321 of the material strip recovery assembly 32 absorbs the pulled material strip under the action of the vacuum generator 322 .
