An electronic-grade fiberglass cloth splicing and sending device

Abstract

This utility model relates to the field of textile machinery, specifically an electronic-grade fiberglass cloth splicing and feeding device. It includes a splicing platform, table legs at the bottom of the platform, a wrinkle-removing mechanism, a feeding mechanism, and a pressing platform. The wrinkle-removing mechanism is located on the side of the splicing platform; the feeding mechanism is located at the end of the platform; and a connecting rod is located on the top of the pressing platform. Through the wrinkle-removing mechanism, a cylinder drives a flattening plate to move back and forth. With the help of the diamond-shaped blocks and the pressing platform, when the flattening plate moves outward from the splicing platform, it presses against the fiberglass cloth, thus smoothing and removing wrinkles.

This effectively removes wrinkles, ensures a flat fabric surface, provides a good foundation for subsequent splicing operations, helps improve the strength of the spliced ​​cloth, and ensures that the spliced ​​fiberglass cloth is not easily detached or broken during use.

Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to an electronic-grade glass fiber cloth splicing and sending device. Background Technology

[0002] Electronic-grade fiberglass cloth is one of the key substrates for manufacturing printed circuit boards. Its splicing and delivery are important steps in the production process, directly affecting product quality and production efficiency.

[0003] Chinese Patent Publication No. CN220723014U discloses an automatic edge-aligning fabric bonding device, including a mounting base, a first drive mechanism, a second drive mechanism, a fabric conveying mechanism, an automatic edge-aligning mechanism, a first extrusion roller, and a second extrusion roller. The second drive mechanism and the automatic edge-aligning mechanism are electrically connected. When the automatic edge-aligning mechanism detects a change in the width of the second fabric, it sends an electrical signal to the second drive mechanism. The second drive mechanism drives the two fabric conveying mechanisms to move closer or further apart, thereby changing the output width of the first fabric, so that the output width of the first fabric matches the width of the second fabric. This invention's automatic edge-aligning mechanism can detect the widths of the first and second fabrics and control the output width of the first fabric through the second drive mechanism, enabling automatic adaptation between the widths of the first and second fabrics. This makes it more convenient, more efficient, and saves labor costs.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing electronic-grade fiberglass cloth splicing and sending devices cannot smooth the cloth before splicing, resulting in many wrinkles on the cloth, which affects the splicing work. At the same time, they cannot automatically clean the transmission rollers, resulting in dust and impurities on the transmission rollers after long-term use, which affects the conveying effect. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that the fabric cannot be smoothed and the conveyor rollers cannot be automatically cleaned before splicing, and to propose an electronic-grade fiberglass fabric splicing and sending device.

[0006] The technical solution of this utility model: an electronic-grade fiberglass cloth receiving and sending device, including a receiving platform and table legs disposed at the bottom of the receiving platform; further comprising:

[0007] The wrinkle removal mechanism is located on the side of the fabric receiving table and is used to smooth the fiberglass cloth and remove wrinkles by moving back and forth before the fabric receiving work.

[0008] The fabric feeding mechanism is located at the end of the fabric receiving table and is used to convey the finished fiberglass cloth outward.

[0009] The extrusion table has a connecting rod on top, which is mounted on the de-wrinkling mechanism. The side of the extrusion table has a diamond-shaped block, and a flat plate is located directly below the diamond-shaped block. Both ends of the extrusion table are set as inclined surfaces. The end of the extrusion table closer to the diamond-shaped block is inclined upward, and the end farther away from the diamond-shaped block is inclined downward. When the diamond-shaped block moves under the action of the de-wrinkling mechanism, it is pressed down by the extrusion table when it passes by, thereby driving the flat plate to smooth the fiberglass cloth.

[0010] Preferably, the wrinkle-removing mechanism includes a power component and a smoothing component;

[0011] The power unit is located on the side of the receiving table and is used to drive the smoothing unit to move back and forth.

[0012] The smoothing component is located at the end of the power component and is used to smooth and remove wrinkles from the fiberglass cloth.

[0013] Preferably, the power assembly includes a cylinder, a connecting frame, a push rod, and a connecting block;

[0014] The connecting frame is located on the side of the receiving table, the cylinder is located on the inside of the connecting frame, the push rod is located at the output end of the cylinder, the connecting block is located at the end of the push rod away from the cylinder, the side of the connecting block is provided with a connecting plate, and the outer side of the connecting plate is slidably provided with a guide frame.

[0015] Preferably, the smoothing component includes a spring and a telescopic rod;

[0016] The telescopic rod is located at the end of the connecting plate away from the connecting block. The bottom of the telescopic rod is connected to the top of the flat plate, and the spring is located on the outside of the telescopic rod.

[0017] Preferably, the fabric feeding mechanism includes a mounting plate, a motor, a rotating shaft, and a gear.

[0018] The mounting plate is located at the end of the receiving platform, the motor is located on the side of the mounting plate, the first rotating shaft is located at the output end of the motor, the first gear is located at the end of the rotating shaft away from the motor, the first gear is located on the side of the first gear and the second gear is meshed with the top of the first gear, the second rotating shaft is located at the center of the second gear and the second gear is located on the side of the second gear.

[0019] Preferably, a fixing bracket is snapped onto the side of the mounting plate, and a collection box is provided at the end of the fixing bracket away from the mounting plate.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] By employing a wrinkle-removing mechanism, a cylinder drives a flattening plate to move back and forth. Through the use of diamond-shaped blocks and a pressing table, the flattening plate presses against the fiberglass cloth as it moves outwards towards the receiving table, smoothing out wrinkles. Conversely, as it moves inwards, the plate detaches from the receiving table, preventing any impact on the smoothness of the fiberglass cloth during the return stroke. This effectively removes wrinkles, ensuring a flat fabric surface and providing a good foundation for subsequent splicing operations. It also helps improve the strength of the spliced ​​fabric, ensuring that the spliced ​​fiberglass cloth is less prone to detachment or breakage during use. Furthermore, it avoids operational errors caused by human factors, improving the accuracy and consistency of splicing, reducing production costs, and increasing economic efficiency.

[0022] With the fabric feeding mechanism in place, the motor drives the first and second fabric transfer rollers to rotate in opposite directions to transport the fiberglass cloth that has been fed into the machine. During the transport process, the dust removal rod removes the dust from the first and second fabric transfer rollers and collects it into the collection box. This effectively removes impurities from the surface of the conveying rollers, prevents the fiberglass cloth from being contaminated, and avoids impurities adhering to the conveying rollers, which could cause scratches, wrinkles, and other defects in the fiberglass cloth during transport. This ensures product quality and allows for continuous operation during production without frequent shutdowns, thereby improving production efficiency. Attached Figure Description

[0028] Example 1

[0029] like Figures 1-2As shown, the present invention proposes an electronic-grade fiberglass cloth receiving and sending device, which includes a receiving platform 1, table legs 2 disposed at the bottom of the receiving platform 1, a wrinkle removal mechanism, a cloth feeding mechanism, and a pressing table 312.

[0030] The wrinkle removal mechanism is located on the side of the fabric receiving table 1 and is used to smooth the fiberglass cloth and remove wrinkles by moving back and forth before the fabric receiving work.

[0031] The fabric feeding mechanism is located at the end of the fabric receiving platform 1 and is used to convey the finished fiberglass cloth outward.

[0032] A connecting rod 311 is provided on the top of the extrusion table 312. The connecting rod 311 is set on the wrinkle removal mechanism. A diamond-shaped block 309 is provided on the side of the extrusion table 312. A flat plate 310 is provided directly below the diamond-shaped block 309. Both ends of the extrusion table 312 are set as inclined surfaces. The end of the extrusion table 312 near the diamond-shaped block 309 is inclined upward, and the end away from the diamond-shaped block 309 is inclined downward. When the diamond-shaped block 309 moves under the drive of the wrinkle removal mechanism, it is pressed down by the extrusion table 312 when it passes through the extrusion table 312, thereby driving the flat plate 310 to smooth the fiberglass cloth.

[0033] The wrinkle-removing mechanism includes a power component and a smoothing component. The power component is located on the side of the receiving table 1 and is used to drive the smoothing component to move back and forth. The smoothing component is located at the end of the power component and is used to smooth and remove wrinkles from the fiberglass cloth. The power component includes a cylinder 301, a connecting frame 302, a push rod 303, and a connecting block 304. The connecting frame 302 is located on the side of the receiving table 1, the cylinder 301 is located inside the connecting frame 302, the push rod 303 is located at the output end of the cylinder 301, and the connecting block 304 is located at the end of the push rod 303 away from the cylinder 301. A connecting plate 306 is provided on the side of the connecting block 304, and a guide frame 305 is slidably provided on the outer side of the connecting plate 306. When the cylinder 301 is activated, the cylinder 301 drives the push rod 303 to move, and the push rod 303 drives the connecting plate 306 to slide within the guide frame 305 through the connecting block 304. The smoothing assembly includes a spring 308 and a telescopic rod 307. The telescopic rod 307 is located at the end of the connecting plate 306 away from the connecting block 304. The bottom of the telescopic rod 307 is connected to the top of the flat plate 310. The spring 308 is located on the outside of the telescopic rod 307. When the cylinder 301 drives the diamond block 309 to move towards the edge of the receiving table 1, the diamond block 309 moves below the extrusion table 312, thereby making the flat plate 310 adhere to the fiberglass cloth for smoothing. When the diamond block 309 moves towards the center of the receiving table 1, the diamond block 309 moves along the upward slope of the extrusion table 312, thereby making the flat plate 310 detach from the fiberglass cloth and avoiding affecting the flatness of the fiberglass cloth during the return stroke.

[0034] Example 2

[0035] like Figures 3-4 As shown, this utility model proposes an electronic-grade fiberglass cloth splicing and sending device. Compared with Embodiment 1, this embodiment details the structure of the feeding mechanism.

[0036] The fabric feeding mechanism includes a mounting plate 401, a motor 402, a first rotating shaft 403, and a first gear 404. The mounting plate 401 is located at the end of the fabric receiving table 1, the motor 402 is located on the side of the mounting plate 401, the first rotating shaft 403 is located at the output end of the motor 402, the first gear 404 is located at the end of the rotating shaft away from the motor 402, a first fabric transfer roller 405 is located on the side of the first gear 404, and a second gear 406 meshes with the top of the first gear 404. A second gear 406 is located at the center of the shaft of the second gear 406. A second rotating shaft 407 is provided, and a second conveying roller 408 is provided on the side of the second gear 406. There are small gaps between the first conveying roller 405 and the second conveying roller 408 for passing fiberglass cloth. The motor 402 drives the first conveying roller 405 and the first gear 404 to rotate clockwise through the first rotating shaft 403. The first gear 404 drives the second gear 406 to rotate counterclockwise. The second gear 406 drives the second conveying roller 408 to rotate counterclockwise through the second rotating shaft 407, thereby transporting the fiberglass cloth outward. A fixing bracket 410 is snapped onto the side of the mounting plate 401. A collection box 411 is provided at the end of the fixing bracket 410 away from the mounting plate 401. There are two fixing brackets 410 on the mounting plate 401, both located on the side of the transfer roller. The side of the collection box 411 near the mounting plate 401 is in contact with the outer side of transfer roller 1 405 and transfer roller 2 408. A dust removal rod 409 is provided on the side of the mounting plate 401 and above the fixing bracket 410. The bottom of the dust removal rod 409 is in contact with the outer side of transfer roller 1 405 and transfer roller 2 408, and the dust removal rod 409 is located directly above the collection box 411. When transfer roller 1 405 and transfer roller 2 408 rotate to the dust removal rod 409, the dust on them is scraped off by the dust removal rod 409 and collected into the collection box 411.

[0037] In summary, when using this invention, one end of the fabric is placed between the first transfer roller 405 and the second transfer roller 408.

The first gear 404 drives the second gear 406 to rotate counterclockwise, and the second gear 406 drives the second transfer roller 408 to rotate counterclockwise via the second rotating shaft 407, thus transporting the fiberglass fabric outwards. During transport, when the first transfer roller 405 and the second transfer roller 408 rotate to the dust removal rod 409, the dust is scraped off by the tip of the dust removal rod 409 and collected in the collection box 411. During the transport of the fiberglass fabric, the cylinder 3 is activated. 01. Cylinder 301 drives push rod 303 to move. Push rod 303 drives connecting plate 306 to slide in guide frame 305 through connecting block 304. When diamond block 309 moves to the edge of receiving table 1, diamond block 309 moves to the bottom of extrusion table 312, so that flat plate 310 is attached to fiberglass cloth for smoothing. When diamond block 309 moves to the center of receiving table 1, diamond block 309 moves along the upward slope of extrusion table 312, so that flat plate 310 is separated from fiberglass cloth. The smoothed fiberglass cloth moves to the bottom of sewing machine 5 for receiving. The fiberglass cloth after receiving continues to be conveyed through conveyor roller 1 405 and conveyor roller 2 408.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
