Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to an RFID narrow-width roll feeding device and its usage method. Background Technology

[0002] RFID (Radio Frequency Identification) antenna substrates (ribbons) are manufactured through dispensing, chip mounting, and thermosetting. Ribbons are divided into wide and narrow ribbons. Wide ribbons are pulled by rollers, and the XY position is compensated by the mounting head when mounting the chip. Narrow ribbons are used for precise ribbon transport to improve production efficiency. Dispensing and mounting are done in fixed positions. Ribbons need to be transported during the production process.

[0003] In related technologies, an automatic composite device for RFID smart tags is disclosed. Its structure includes a fixed circular plate, a fixed base, a blade bottom fixing component, a vacuum adsorption roller, a bottom blade, a side fixing connector, an adjusting screw, an adjusting handle, a sponge pressure roller, a lower fixing connector, a sealing plate, a suction chamber sealing plate, a fixed front plate, a cutter, an upper fixing connector, a blade roller, a limit nut, a fixed rear plate, a power feeding device, and a wet inlay peeling device. The fixed circular plate is threadedly connected to the fixed base via bolts, and the fixed base is connected to the blade bottom fixing component. In use, the tag is placed on the vacuum adsorption roller, and its rotation engages with the sponge pressure roller to stop the vacuum adsorption roller from rotating. Then, it is cut by the cutter.

[0004] Regarding the aforementioned technologies, by placing the label on the vacuum adsorption roller, the rotation of the vacuum adsorption roller needs to be stopped before the cutter can cut the material, which makes it impossible to continuously convey the material strip. Summary of the Invention

[0005] To address the issue of uninterrupted feeding, this application provides an RFID narrow-width roll material feeding device and its usage method.

[0006] The RFID narrow-width roll material feeding device and its usage method provided in this application adopt the following technical solution:

[0007] An RFID narrow-width roll material feeding device includes a support assembly, four clamping assemblies, and two first drive assemblies. The support assembly includes a support plate mounted on a worktable. The four clamping assemblies are located on the side of the support plate away from the worktable and are distributed along one long side of the support plate. Among the four clamping assemblies, the two middle clamping assemblies are inner clamping assemblies, and the other two are outer clamping assemblies. The clamping assemblies are capable of reciprocating along one long side of the support plate and are used to clamp the material strip.

[0008] Two first drive components are fixed to the support plate and are distributed along the length of the long side of the support plate. One of the first drive components is connected to the inner clamping component to drive the inner clamping component to move, and the other first drive component is connected to the outer clamping component to drive the outer clamping component to move.

[0009] By adopting the above technical solution, when it is necessary to transfer the material belt, firstly, the two clamping components located in the middle are activated. Then, the material belt to be transferred is placed on the clamping components, which clamp the material belt. Next, one of the first drive components is activated, which drives the two inner clamping components to move in the same direction. When the material belt moves to the designated position, the outer clamping component is activated to clamp the material belt. After that, the inner clamping components are activated again, and the two inner clamping components separate from the material belt. Then, the other... A first driving component drives the outer clamping component to move in the same direction. At this time, the inner clamping component returns to its original working position and clamps the material belt again. Following the above steps, the material is fed again, realizing the transmission of the material belt. Compared with related technologies, this application achieves uninterrupted feeding by alternately feeding with two sets of inner and outer clamping components. The clamping components can transmit over long distances, make short-distance fine-tuning and corrections, and complete transmission movements in both forward and reverse directions, which helps to improve the problem of not being able to carry out uninterrupted conveying.

[0010] Optionally, a partition is fixed in the middle of the support plate, which divides the support plate into two identical chambers, with the two first drive components located on both sides of the partition.

[0011] Each of the two first drive components includes a lead screw and a first drive motor. The lead screw is horizontally located in one of the chambers. The direction of the lead screw is consistent with the length direction of the long side of the support plate. One end of the lead screw is rotatably connected to the support plate, and the other end is rotatably connected to the partition plate. The first drive motor is fixed to the support plate and is connected to the lead screw to drive the lead screw to rotate.

[0012] One of the clamping components in the inner clamping assembly is connected to a lead screw in one of the first drive assemblies, and one of the clamping components in the outer clamping assembly is connected to a lead screw in the other first drive assemblies. The inner clamping component and the outer clamping component each move along the length of a lead screw.

[0013] By adopting the above technical solution, when the inner clamping component clamps the material strip, one of the first drive motors is started. The first drive motor drives the lead screw to rotate. During the rotation of the lead screw, the inner clamping component can move along the length of the lead screw. The material strip moves with the clamping component, which can transmit the material strip. Subsequently, the material strip is clamped by the outer clamping component, and another first drive motor is started to make the outer clamping component move. By setting the first drive motor, it is beneficial to transmit the material strip.

[0014] Optionally, a second driving assembly is also included. The second driving assembly is located below the support plate. The second driving assembly includes a placement seat, a placement plate, and a driving member. The placement seat is mounted on the worktable. The placement plate is located on the side of the placement seat near the support plate. The placement plate is fixed to the support plate. The placement plate is horizontally slidably disposed on the placement seat. The placement plate slides along the surface of the placement seat. The sliding direction of the placement plate is perpendicular to the sliding direction of the clamping assembly. The driving member is fixed to the placement seat and is connected to the placement plate to drive the placement plate to slide.

[0015] By adopting the above technical solution, the material belt is transported. When the material belt needs to be corrected, the drive unit is activated, which drives the placement plate to move. At this time, the support plate moves synchronously with the placement plate, and the support plate drives the clamping component to move, which enables the material belt to move. The vision system positions the front and rear labels, calculates the position coordinates and replenishment amount of the transported labels, and completes the correction through the cooperation of the first drive component and the second drive component. The second drive component facilitates the positioning of the material belt.

[0016] Optionally, the clamping assembly includes a connecting plate, a fixing plate, a pushing member, a first clamping plate, and a second clamping plate. The connecting plates in the two inner clamping assemblies are fixedly connected, and the connecting plates in the two outer clamping assemblies are fixed. One of the connecting plates in the two inner clamping assemblies and one of the connecting plates in the two outer clamping assemblies are each threadedly connected to a lead screw. The fixing plate is fixed to the connecting plate, and the pushing member is fixed to the fixing plate. The pushing member is connected to the second clamping plate to drive the second clamping plate to move closer to or away from the first clamping plate. The first clamping plate is fixed to the fixing plate, and the first clamping plate and the second clamping plate clamp the material strip.

[0017] By adopting the above technical solution, when it is necessary to transfer the material belt, firstly, the pusher in the inner clamping assembly is activated, and the pusher pulls the second clamping plate away from the first clamping plate. Then, the material belt to be transferred is placed on the first clamping plate, and the pusher is activated again, and the pusher pushes the second clamping plate to move closer to the first clamping plate, so that the first and second clamping plates clamp the material belt. Then, the second drive motor is driven, which enables the lead screw to rotate, and the connecting plate moves along the length of the lead screw to transfer the material belt. By setting the first and second clamping plates, it is convenient to clamp the material belt.

[0018] Optionally, the pushing component includes a first cylinder, which is vertically arranged, with its cylinder body fixed to the fixing plate, its piston rod facing the connecting plate, and the piston rod fixed to the second clamping plate.

[0019] By adopting the above technical solution, when it is necessary to clamp the material strip, the two first cylinders in the inner clamping assembly are activated simultaneously. The first cylinders pull the second clamping plate away from the first clamping plate. Then, the material strip is placed on the first clamping plate, and the first cylinders are activated again. The second clamping plate and the first clamping plate can clamp the material strip. By setting the first cylinders, it is beneficial to realize the automation of the clamping operation.

[0020] Optionally, the clamping assembly further includes two clamping members, each clamping member including a fixed frame, a sliding rod, and a second cylinder. One of the fixed frames is fixed to the fixed plates of the two inner clamping assemblies, and the other fixed frame is fixed to the fixed plates of the two outer clamping assemblies. The sliding rod is located on the side of the fixed frame near the support plate and is slidably disposed on the fixed frame. The sliding rod moves toward or away from the support plate and is fixed to the second clamping plate. The second cylinder is fixed to the fixed frame and is connected to the sliding rod to drive the sliding rod to move.

[0021] By adopting the above technical solution, when it is necessary to clamp the material strip, firstly, the clamping component located in the inner clamping assembly is activated. Only the second cylinder needs to be activated. The second cylinder pulls the sliding rod away from the support plate. At this time, the second clamping plate moves synchronously with the sliding rod. Then, the material strip is placed on the first clamping plate. The second cylinder is activated again. The second cylinder pushes the sliding rod towards the support plate. The second clamping plate moves towards the first clamping plate. The first and second clamping plates can clamp the material strip. By setting the clamping component, only one second cylinder needs to be activated to make the first and second clamping plates in the two inner clamping assemblies clamp the material strip.

[0022] Optionally, the clamping assembly further includes a positioning element, which is fixed to the fixing plate and close to the first clamping plate. The positioning element is used to position the material strip.

[0023] By adopting the above technical solution, when it is necessary to clamp the material strip, the second clamping plate is driven to move away from the first clamping plate, and the material strip is placed on the first clamping plate so that one side of the material strip contacts the positioning element. Then, the material strip is clamped by the second clamping plate and the first clamping plate. By setting the positioning element, it is convenient to position the material strip. After that, the first clamping plate and the second clamping plate clamp the material strip.

[0024] Optionally, the positioning component includes a positioning block, a positioning plate, and a screw. The positioning block is fixed to the fixing plate, the positioning plate is slidably disposed on the positioning block, and the positioning plate is capable of moving along the positioning block toward or away from the connecting plate. The screw passes through the positioning plate and is connected to the positioning block. The screw is sequentially threaded to the positioning plate and the positioning block.

[0025] By adopting the above technical solution, the first clamping plate is driven to move away from the first clamping plate, and the screw is turned to separate the screw from the positioning block. Then, according to the actual situation, the positioning plate is moved closer to or further away from the connecting plate. When the positioning plate moves to the appropriate position, the screw is turned in the opposite direction, and the screw can fix the positioning block. At this time, the screw fixes the positioning plate and the positioning block. Then, the material strip is placed on the first clamping plate, so that one side of the material strip contacts the positioning plate, and then the material strip is clamped. The positioning plate is slidably set on the positioning block, which is conducive to adjusting the position of the positioning plate and positioning the material strip.

[0026] Optionally, it also includes an adsorption assembly, which includes an adsorption plate fixed to the side of the support plate away from the worktable, and the adsorption plate is used to perform vacuum adsorption on the material strip.

[0027] By adopting the above technical solution, the material belt transmission is completed. At this time, the adsorption plate is activated, and the adsorption plate simultaneously adsorbs the material belt to ensure the stability of the material belt position during correction.

[0028] A method for using an RFID narrow-width roll material feeding device, characterized by the following steps:

[0029] S1: Activate the clamping assembly so that the two inner clamping assemblies in the middle clamp the material strip, and the first driving assembly drives the two inner clamping assemblies to move in the same direction;

[0030] S2: The two outer clamping components clamp the material strip. When the two inner clamping components separate from the material strip, the other first driving component is activated. The first driving component drives the outer clamping components to move in one direction simultaneously.

[0031] S3: At the same time, the clamping component returns to its original working position, waits for the outer clamping component to open, and then clamps the material strip through the inner clamping component to complete the feeding again. By following the above steps, uninterrupted feeding can be completed.

[0032] S4: The second drive component adjusts and positions the material belt.

[0033] By adopting the above technical solution and following the above operating steps, the outer clamping component and the inner clamping component clamp the material strip, and the first driving component drives the outer clamping component and the inner clamping component to move, thereby completing uninterrupted feeding.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. Compared with related technologies, this application achieves uninterrupted feeding by alternating feeding of two sets of inner clamping components and outer clamping components. The clamping components can transmit over long distances, make fine adjustments and corrections over short distances, and complete transmission movements in both forward and reverse directions, which helps to improve the problem of uninterrupted feeding.

[0057] The implementation principle of Example 1 is as follows: When it is necessary to convey the material belt 6, firstly, the clamping component 2 is activated, so that the two inner clamping components in the middle clamp the material belt 6. Then, one of the first drive components 3 is activated, and the first drive component 3 drives the two inner clamping components to move in the same direction. When the material belt 6 moves to the designated position, the two outer clamping components clamp the material belt 6. When the two inner clamping components separate from the material belt 6, the other first drive component 3 is activated, and the first drive component 3 drives the outer clamping components to move in one direction at the same time. During the same time, the clamping components return to the original working position, wait for the outer clamping components to open, and then clamp the material belt 6 through the inner clamping components to complete the feeding again. According to the above steps, uninterrupted feeding can be completed. Finally, the second drive component 5 is activated to adjust and position the material belt 6.

[0058] When the material strip 6 needs to be clamped by the clamping assembly 2, firstly, the material strip 6 is clamped by the inner clamping assembly. At the same time, the two first cylinders 242 located on the inner clamping assembly are activated. The first cylinders 242 pull the slide plate 23 to move away from the connecting plate 21. At this time, the second clamping plate 26 moves synchronously with the slide plate 23 and moves away from the first clamping plate 25. Then, the material strip 6 is placed on the first clamping plate 25. The first cylinders 242 located on the inner clamping assembly are activated again. The first cylinders 242 push the slide plate 23 to move closer to the connecting plate 21, so that the first clamping plate 25 and the second clamping plate 26 clamp the material strip 6. Subsequently, the material strip 6 is conveyed.

[0059] When it is necessary to convey the material belt 6, the first drive motor 32 is started, and the first drive motor 32 drives the lead screw 31 to rotate. At this time, the sliding seat 215 can slide on the lead screw 31 along the length direction of the lead screw 31, and the connecting plate 21 moves synchronously with the sliding seat 215, which can convey the material belt 6.

[0060] Example 2

[0061] Reference Figure 7The difference between this embodiment and embodiment 1 lies in the clamping assembly 2. The clamping assembly 2 further includes two clamping members 28, each close to the fixing plate 22 in the inner clamping assembly and the fixing plate 22 in the outer clamping assembly. Each clamping member 28 includes a fixing frame 281, a sliding rod 282, two moving rods 283, two second locking blocks 284, and a second cylinder 285. In this embodiment, the fixing frame 281 is a U-shaped frame, with its opening facing the fixing plate 22. The fixing frame 281 is horizontally positioned. One fixing frame 281 is welded to the two fixing plates 22 of the inner clamping assembly, and the other fixing frame 281 is welded to the two fixing plates 22 of the outer clamping assembly. The sliding rod 282 is horizontally positioned on the side of the fixing frame 281 closest to the connecting plate 21 and the fixing plate 22. The setting direction of 82 is consistent with the length direction of the long side of the support plate 11. The sliding rod 282 is slidably set on the fixed frame 281. The sliding rod 282 can move towards or away from the support plate 11. Two moving rods 283 are each vertically located at both ends of the sliding rod 282. The moving rods 283 are welded to the sliding rod 282. The end of the moving rod 283 away from the sliding rod 282 is welded to the second locking block 284. The second locking block 284 is located in the locking groove 232 and fits into the locking groove 232. The second cylinder 285 is located on the side of the fixed frame 281 away from the sliding rod 282. The second cylinder 285 is vertically set. The cylinder body of the second cylinder 285 is fixedly connected to the fixed frame 281 by screws. The piston rod of the second cylinder 285 passes through the fixed frame 281 and is welded to the sliding rod 282. The second cylinder 285 drives the sliding rod 282 to move.

[0062] The implementation principle of Example 2 is as follows: When the clamping assembly 2 needs to clamp the material strip 6, simply activate the second cylinder 285 located on the inner clamping assembly. The second cylinder 285 pulls the sliding rod 282 to move away from the support plate 11. At this time, the sliding rod 282 drives the slide plate 23 to move away from the connecting plate 21. At this time, the second clamping plate 26 moves synchronously with the slide plate 23 and moves away from the first clamping plate 25. Then, place the material strip 6 on the first clamping plate 25, and activate the second cylinder 285 located on the inner clamping assembly 2 again. The second cylinder 285 pushes the sliding rod 282 to move closer to the support plate 11. At this time, the sliding rod 282 drives the slide plate 23 to move closer to the connecting plate 21, so that the first clamping plate 25 and the second clamping plate 26 clamp the material strip 6. Subsequently, the material strip 6 is conveyed.

[0063] A method for using an RFID narrow-width roll material feeding device includes the following steps:

[0064] S1: Start the clamping assembly 2 so that the two inner clamping assemblies in the middle clamp the material belt 6, and start one of the first drive assemblies 3. The first drive assemblies 3 drive the two inner clamping assemblies to move in the same direction.

[0065] S2: When the material belt 6 moves to the designated position, the two outer clamping components clamp the material belt 6. When the two inner clamping components separate from the material belt 6, the other first drive component 3 is started. The first drive component 3 drives the outer clamping components to move in one direction at the same time.

[0066] S3: At the same time, the clamping component returns to its original working position, waits for the outer clamping component to open, and then clamps the material belt 6 through the inner clamping component to complete the feeding again. Following the above steps, uninterrupted feeding can be completed.

[0067] S4: Start the second drive component 5 to adjust and position the material belt 6.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
