Description

Technical Field

[0001] This invention relates to the field of detection technology, and more specifically, to a sampling device for fixed weight and length of fiberglass yarn bundles. Background Technology

[0002] In the glass fiber production process, the quality inspection of glass fiber yarn is a crucial step in ensuring product qualification rates. By sampling glass fiber yarn bundles at fixed weights or lengths and conducting subsequent testing, abnormal fluctuations in the production process can be detected in a timely manner, allowing for targeted adjustments to relevant process steps. The sampling accuracy of glass fiber yarn directly affects the reliability of the test results, which in turn influences product quality judgment and batch release decisions.

[0003] Currently, sampling of fiberglass yarn bundles is generally done manually. The specific process is as follows: the operator manually extracts a certain length of fiberglass yarn from the bundle, or uses a simple scale to weigh a certain mass of fiberglass yarn sample, and then sorts and sends it to the testing stage.

[0004] During manual sampling, operators rely on visual inspection and touch to judge the sample length or mass, making precise control difficult. For fixed-length sampling, manually pulling the fiberglass yarn introduces length errors, with variations between operators reaching ±5%-10%. For fixed-weight sampling, the manual weighing process is affected by environmental vibrations, operating techniques, and reading errors, resulting in significant fluctuations in sample mass. Insufficient sampling accuracy will directly lead to subsequent test data deviating from the true value, potentially causing qualified products to be misjudged as unqualified, or unqualified products to enter the next stage. Summary of the Invention

[0005] The purpose of this invention is to provide a fixed-weight and fixed-length sampling device for fiberglass yarn bundles, which can improve the sampling accuracy of fiberglass yarn bundles.

The fixed-length sampling component, the fixed-weight sampling component, and the winding shaft are all mounted on the sampling plate; The fixed-length sampling device is used to pull out the required length of fiberglass yarn from the fiberglass yarn roll, cut the fiberglass yarn, and then wind it onto the winding spool. The fixed-weight sampling device is used to pull out the required weight of fiberglass yarn from the fiberglass yarn roll, cut the fiberglass yarn, and then wind it onto the winding spool. The winding shaft is rotatably mounted on the sampling plate, and the rotation axis of the winding shaft is perpendicular to the sampling plate.

The movable clamp returns to its original position, and the fixed clamp B releases the fiberglass yarn. The winding shaft winds up the fiberglass yarn. During the winding process, when the reduction value of the weighing component reaches the required weight in grams, the winding shaft stops rotating, and the shearing component cuts the fiberglass yarn.

It also includes a mounting frame, and the installation disc is slidably mounted on the mounting frame. The first driving member is mounted on the mounting frame for driving the winding shaft to rotate. The installation disc slides in a direction perpendicular to the sampling plate.

The second linear module is used to drive the material handling tray to move along a linear direction. The first linear module drives the material handling claw to remove the fiberglass yarn bundle from the winding shaft and place the fiberglass yarn bundle inside the detection cup. Then, the second linear module transports the detection cup to the loading position.

[0015] Optionally, it also includes a mounting plate, which is disposed on the first linear module. The picking claw is disposed on the mounting plate.

The operator manually passes the end of the fiberglass yarn through the conveying guide and clamping mechanism. Select either the fixed-length sampling mode or the fixed-weight sampling mode. After selecting the mode, the corresponding fixed-length or fixed-weight sampling component automatically pulls out the required length or weight of fiberglass yarn from the roll. The shearing component cuts the fiberglass yarn, and the winding shaft rotates under the drive of the first drive component, winding the cut fiberglass yarn into a ball, completing the sampling. This process replaces the traditional manual pulling of fiberglass yarn, visual length estimation, and handheld weighing, achieving full automation of fixed-length and fixed-weight sampling of fiberglass yarn balls. Compared with manual operation, the mechanically driven pulling, shearing, and winding actions have higher repeatability and consistency, effectively avoiding the ±5%-10% length / weight deviation caused by visual error, tactile differences, and different operating techniques in manual sampling. This ensures sampling accuracy from the source, allowing subsequent test data to more accurately reflect product quality. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] The following is for reference Figures 1-6 As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides a fiberglass yarn ball fixed-weight and fixed-length sampling device, referring to... Figure 1 It includes a chassis 1 and a sampling device 2: Reference Figure 1 and Figure 2 The sampling device 2 is installed on the chassis 1. The sampling device 2 includes a sampling plate 21, a fixed-length sampling component 22, a fixed-weight sampling component 23, and a winding shaft 24. Reference Figure 1 and Figure 2 The fixed-length sampling component 22, the fixed-weight sampling component 23, and the winding shaft 24 are all set on the sampling plate 21; Reference Figure 1 and Figure 2 The fixed-length sampling component 22 is used to pull out the required length of fiberglass yarn 27 from the fiberglass yarn 27 roll, cut the fiberglass yarn 27, and then wind it onto the winding shaft 24. The fixed-weight sampling component 23 is used to cut the fiberglass yarn 27 after pulling out the required weight from the fiberglass yarn 27 roll, and then wind it onto the winding spool 24. Reference Figure 1 and Figure 2 The winding shaft 24 is rotatably mounted on the sampling plate 21, and the rotation axis of the winding shaft 24 is perpendicular to the sampling plate 21. The sampling device 2 also includes a first driving member for driving the winding shaft 24 to rotate and winding the cut glass fiber yarn 27 into a ball.

[0022] When sampling fiberglass yarn 27, the fiberglass yarn 27 roll is placed in the designated position on the equipment, and the operator manually passes the end of the fiberglass yarn 27 through the conveying guide 9 and the clamping mechanism. A fixed-length sampling mode or a fixed-weight sampling mode is selected. After selecting a mode, the corresponding fixed-length sampling component 22 or fixed-weight sampling component 23 automatically pulls out the required length or weight of fiberglass yarn 27 from the roll. The cutting component 223 cuts the fiberglass yarn 27, and the winding shaft 24 rotates under the drive of the first driving component, winding the cut fiberglass yarn 27 into a ball, completing the sampling.

[0023] Reference Figure 2 In this embodiment of the application, the fixed-length sampling member 22 includes a fixed gripper A221, a movable gripper 222, and a shearing member 223; Reference Figure 2 The fixed gripper A221 is fixedly disposed on the sampling plate 21, the movable gripper 222 is slidably disposed on the sampling plate 21, the fixed length sampling component 22 also includes a second driving component, the second driving component is used to drive the movable gripper 222 to slide along the length direction of the sampling plate 21, and the shearing component 223 is disposed on the sampling plate 21 and close to the fixed gripper A221. Reference Figure 2 and Figure 3The second driving component includes a drive motor 224, drive wheels 225, a drive belt 226, and a limiting guide rail 227. The drive motor 224 is a servo motor 16. Both the drive motor 224 and the drive wheels 225 are mounted on the sampling plate 21. There are two drive wheels 225, both rotatably mounted on the sampling plate 21. The drive motor 224 is located on the back of the sampling plate 21, and its output shaft passes through the sampling plate 21. Any one of the drive wheels 225 is coaxially mounted on the output shaft of the drive motor 224. The drive belt 226 is sleeved on the two drive wheels 225. The limiting guide rail 227 is fixedly mounted on the sampling plate 21 and is parallel to the drive belt 226. In the direction of operation of 6, the movable gripper 222 is fixedly mounted on the drive belt 226 and slidably engaged on the limit guide rail 227. When sampling the glass fiber yarn 27 to a fixed length, the glass fiber yarn 27 is passed through the fixed gripper A221 and the movable gripper 222. The movable gripper 222 clamps the glass fiber yarn 27, and the fixed gripper A221 releases the glass fiber yarn 27. The second drive unit drives the movable gripper 222 to move and drive the glass fiber yarn 27 to unwind. After the glass fiber yarn 27 is unwound to the required length, the fixed gripper A221 clamps the glass fiber yarn 27. After the glass fiber yarn 27 is clamped and fixed by the fixed gripper A221 and the movable gripper 222, the shearing member 223 cuts the glass fiber yarn 27 and winds it onto the winding shaft 24.

[0024] In fixed-length sampling mode, the operator passes the fiberglass yarn 27 through the fixed gripper A221 and the movable gripper 222. The movable gripper 222 clamps the fiberglass yarn 27, and the fixed gripper A221 releases the fiberglass yarn 27. The second drive unit drives the movable gripper 222 to translate along the length direction of the sampling plate 21, causing the fiberglass yarn 27 to unwind from the yarn roll. When the movable gripper 222 translates to a set distance (corresponding to the required length of fiberglass yarn 27), the fixed gripper A221 clamps the fiberglass yarn 27. At this time, the fiberglass yarn 27 is simultaneously held and fixed in two positions by the fixed gripper A221 and the movable gripper 222. The shearing member 223 cuts the fiberglass yarn 27 near the fixed gripper A221, and the first drive unit drives the winding shaft 24 to rotate and wind the cut fiberglass yarn 27 into a ball. The precise translational movement of the movable gripper 222 achieves precise control of the length of the fiberglass yarn 27. The translational distance of the moving gripper 222 is precisely driven by the servo motor 16, which greatly improves the length control accuracy compared to manually pulling the fiberglass yarn 27 and visually estimating its length. The dual-point clamping and fixing of the fixed gripper A221 and the moving gripper 222 ensures that the fiberglass yarn 27 is in a taut state during cutting, and the length of the fiberglass yarn 27 segment after cutting is consistent with the set value, avoiding length errors caused by the slack or stretching of the fiberglass yarn 27 during manual sampling.

[0025] Reference Figure 1 and Figure 2 In this embodiment of the application, the fixed-weight sampling component 23 includes a fixed gripper B231 and a weighing component; Reference Figure 1 and Figure 2 The fixed gripper B231 is set on the sampling plate 21, and the fixed gripper B231 and the fixed gripper A221 are located on both sides of the winding shaft 24 respectively. Reference Figure 1 and Figure 2 27 rolls of fiberglass yarn are located on the weighing device, which includes an electronic scale 232, a logic controller and a computer. The electronic scale 232 is connected to the computer via the logic controller to transmit data from the electronic scale 232 to the computer and record it. When the fiberglass yarn 27 is sampled for fixed weight, the fiberglass yarn 27 passes through the fixed clamp A221 and the movable clamp 222. The movable clamp 222 clamps the fiberglass yarn 27, and the fixed clamp A221 releases the fiberglass yarn 27. The second driving member is used to drive the movable clamp 222 to move and move the clamping end of the fiberglass yarn 27 past the fixed clamp B231. The fixed clamp B231 clamps the fiberglass yarn 27. The movable clamp 222 returns to the original position, and the fixed clamp B231 releases the fiberglass yarn 27. The winding shaft 24 winds the fiberglass yarn 27. During the winding process of the fiberglass yarn 27, when the reduction value of the weighing device reaches the fixed weight requirement in grams, the winding shaft stops rotating, and the shearing member 223 cuts the fiberglass yarn 27.

[0026] By using real-time feedback signals of weight changes from the weighing device to control the start and stop of the winding shaft 24, precise closed-loop control of the weight of the fiberglass yarn 27 is achieved. Compared to manual weighing using simple scales, which is affected by environmental vibrations, operating techniques, and reading errors, this solution uses the linkage control between the electronic scale and the servo motor 16 to monitor weight changes in real time during the winding process of the fiberglass yarn 27 and stop immediately when the target value is reached. This significantly improves the accuracy of weight control and effectively avoids distortion of test results caused by sampling weight deviations.

[0027] Reference Figure 2 In this embodiment, the fixed gripper A221, the movable gripper 222, and the fixed gripper B231 each include a first gripper 3, a second gripper 4, a mounting base 5, and a cylinder 6. The first gripper 3 and the second gripper 4 are both mounted on the mounting base 5 and slidably disposed thereon. The clamping surfaces of the first gripper 3 and the second gripper 4 are each provided with mutually cooperating stepped grooves 7. Fiberglass yarn 27 is located between the first gripper 3 and the second gripper 4. The cylinder 6 is used to drive the first gripper 3 and the second gripper 4 to move closer together, clamping the fiberglass yarn 27 within the stepped grooves 7. The stepped groove 7 structure allows the same gripper to accommodate fiberglass yarn 27 of different diameters (such as single-strand, multi-strand, or fiberglass yarn 27 with different values), achieving universal clamping without changing the grippers. The gradual clamping space provided by multiple steps makes the clamping force applied by the gripper to the fiberglass yarn 27 more evenly distributed, avoiding damage or deformation of the fiberglass yarn 27 caused by concentrated clamping force, and ensuring the integrity of the physical properties of the fiberglass yarn 27 during the sampling process.

[0028] Reference Figure 2 Furthermore, the mounting base 5 of the fixed gripper A221 is fixedly mounted on the sampling plate 21 by an L-shaped plate; Reference Figure 2 Furthermore, the mounting base 5 of the movable gripper 222 is fixedly mounted on the drive belt 226 and slidably engaged with the limit guide rail 227; Reference Figure 2 Furthermore, the fixed gripper B231 is slidably mounted on the sampling plate 21, and a lifting cylinder 8 is fixedly mounted on the drive plate. The piston rod of the lifting cylinder 8 is in the vertical direction, and the mounting base 5 of the fixed gripper B231 is fixedly mounted on the piston rod of the lifting cylinder 8.

[0029] In constant weight mode, after the moving gripper 222 drives the end of the fiberglass yarn 27 past the fixed gripper B231, the lifting cylinder 8 is activated. The lifting cylinder 8 drives the fixed gripper B231 to move downward, so that the fiberglass yarn 27 enters the interior of the fixed gripper B231, and then clamps the fiberglass yarn 27.

[0030] Reference Figure 2 In this embodiment, the sampling plate 21 is provided with a conveying guide 9, which is located in front of the fixed gripper A221. The conveying guide 9 includes a first ceramic guide ring 91, a second ceramic guide ring 92, and a pagoda tensioner 93 disposed between the first ceramic guide ring 91 and the second ceramic guide ring 92. The pagoda tensioner 93 is used to provide adjustable tension to the fiberglass yarn 27. The fiberglass yarn 27 passes through the first ceramic guide ring 91, the second ceramic guide ring 92, and the pagoda tensioner 93 before entering the fixed gripper A221. After the fiberglass yarn 27 is released from the yarn roll, it passes through the first ceramic guide ring 91, the pagoda tensioner 93, and the second ceramic guide ring 92 in sequence before entering the fixed gripper A221. During operation, the pagoda tensioner 93 applies adjustable friction to the fiberglass yarn 27 through its conical structure, ensuring that the fiberglass yarn 27 maintains a stable tension during the pulling process of the moving gripper 222. The ceramic guide ring has wear-resistant and smooth properties, effectively reducing frictional damage to the fiberglass yarn 27 during the guiding process. The pagoda tensioner 93 provides stable, uniform, and adjustable tension to the fiberglass yarn 27, ensuring that the fiberglass yarn 27 is in a constant tension state during the pulling and winding process, avoiding length measurement deviations or poor winding formation caused by tension fluctuations, and improving the consistency and reliability of sampling.

[0031] Reference Figure 2 , Figure 4 and Figure 5In this embodiment, the sampling plate 21 has a cross-shaped mounting notch 10. A mounting plate 11 is mounted on the sampling plate 21 through the mounting notch 10. The winding shaft 24 is rotatably mounted on the mounting plate 11. The winding shaft 24 has a receiving notch 12 for the fiberglass yarn 27 to pass through. The system also includes a mounting frame 13. The mounting plate 11 is slidably mounted on the mounting frame 13. A first driving member is mounted on the mounting frame 13 to drive the winding shaft 24 to rotate. The mounting plate 11 slides in a direction perpendicular to the sampling plate 21. A third driving member is mounted on the mounting frame 13 to drive the mounting plate 11 to slide and thus the winding shaft 24 to slide. The retractable design of the winding shaft 24 allows it to be hidden behind the sampling plate 21 when not in operation, without interfering with the normal operation of other mechanisms (such as grippers and shearing components 223). When in operation, it extends and uses the receiving notch 12 to hook the end of the fiberglass yarn 27 for winding. The structure is compact and the operation is reliable. This design makes the working space on the front of the sampling plate 21 more concise, making it easier for operators to observe and maintain.

[0032] In fixed-length mode, after the glass fiber yarn 27 is removed to the required length by the moving jaw 222, the first driving member drives the mounting plate 11 to extend the winding shaft 24, so that the glass fiber yarn 27 enters the receiving notch 12. Then, the shearing member 223 cuts the glass fiber yarn 27, and the third driving member drives the winding shaft 24 to rotate, and the winding shaft 24 rotates to wind up the cut glass fiber yarn 27. In fixed-weight mode, when the moving jaw 222 drives the end of the glass fiber yarn 27 past the fixed jaw B231, the fixed jaw B231 descends to clamp the glass fiber yarn 27. The moving jaw 222 returns to the initial position, and then the first and third driving members drive the winding shaft 24 to move, so that the glass fiber yarn 27 enters the winding shaft 24. Then, the winding shaft 24 rotates to open the winding and wind up the glass fiber yarn 27. During this process, the fixed jaw B231 releases the glass fiber yarn 27. Once the electronic scale 232 reaches the measured weight, the winding shaft 24 stops winding, and the shearing piece 223 cuts the fiberglass yarn 27.

[0033] Reference Figure 2 , Figure 4 and Figure 5 In this embodiment, the shearing component 223 includes a pneumatic shear 2231 and a vertical cylinder 2232. The vertical cylinder 2232 is fixedly mounted on the sampling plate 21, and the length direction of the piston rod of the vertical cylinder 2232 is parallel to the length direction of the sampling plate 21. The fixing seat of the pneumatic shear 2231 is fixedly mounted on the piston rod of the vertical cylinder 2232. When it is necessary to cut the fiberglass yarn 27, the vertical cylinder 2232 is first activated to drive the pneumatic shear 2231 to move, so that the fiberglass yarn 27 enters the range of the pneumatic shear 2231. Then, the pneumatic shear 2231 cuts the fiberglass yarn 27. The operation is simple and convenient.

[0034] Reference Figure 2 , Figure 4 and Figure 5 In this embodiment, the mounting bracket 13 is fixedly mounted on the chassis 1. The third driving component includes a first electric cylinder 14 and a sliding bracket 15. The mounting plate 11 is mounted on the sliding bracket 15, which is located on the back of the sampling plate 21. The sliding bracket 15 is slidably mounted on the mounting bracket 13, and its sliding direction is perpendicular to the sampling plate 21. The first electric cylinder 14 is fixedly mounted on the mounting bracket 13, and the sliding bracket 15 is fixedly mounted on the output shaft of the first electric cylinder 14. When the winding shaft 24 needs to be extended, the first electric cylinder 14 drives the sliding bracket 15 to slide in a direction perpendicular to the sampling plate 21, causing the mounting plate 11 and the winding shaft 24 to extend from the mounting notch 10 to the front of the sampling plate 21. After sampling is completed, the first electric cylinder 14 reverses and drives the sliding bracket 15 to reset, and the winding shaft 24 retracts to the back of the sampling plate 21. The driving method of the first electric cylinder 14 in conjunction with the sliding bracket 15 achieves precise control of the extension and retraction movement of the winding shaft 24, resulting in smooth movement and accurate positioning. The layout, located on the back of the sampling plate 21, keeps the front of the equipment clean and facilitates operation and maintenance. Compared to the pneumatic cylinder 6, the electric cylinder drive offers better position control precision and speed adjustment capabilities, allowing for flexible adjustment of the extension speed and position of the winding shaft 24 according to process requirements.

[0035] Reference Figure 2 , Figure 4 and Figure 5 In this embodiment, the sliding frame 15 includes a sliding plate 151, a first connecting rod 152, a fixing plate 153, and a second connecting rod 154. Multiple first connecting rods 152 and second connecting rods 154 are provided and respectively disposed around the sliding plate 151 and the fixing plate 153. The sliding plate 151 is parallel to the sampling plate 21 and is slidably mounted on the mounting frame 13. The first connecting rod 152 is fixedly mounted on the sliding plate 151, and the fixing plate 153 is fixedly mounted at the end of the first connecting rod 152. The second connecting rod 154 is fixed... The mounting plate 11 is fixedly mounted on the second connecting rod 154 on the plate surface of the fixed plate 153 opposite to the first connecting rod 152. The first driving component includes a servo motor 16, a first pulley 17, a second pulley 18, and a conveyor belt 19.

[0037] Reference Figure 3 and Figure 6 In this embodiment, a material handling device 20 is also provided on the chassis 1. The material handling device 20 includes a material handling claw 201, a material handling tray 202, a detection cup 203, a first linear module 204, and a second linear module 205. The material handling claw 201 is provided on the first linear module 204 and is used to drive the material handling claw 201 to move along a three-axis direction. The material handling tray 202 is provided on the second linear module 205 and is provided with a plurality of first notches 25 for placing the detection cup 203. The second linear module 205 is used to drive the material handling tray 202 to move along a linear direction. The first linear module 204 drives the material handling claw 201 to take out the fiberglass yarn 27 bundles on the winding shaft 24 and place the fiberglass yarn 27 bundles into the detection cup 203. Then, the second linear module 205 transports the detection cup 203 to the loading position.

[0038] After the fiberglass yarn 27 is wound into a ball on the winding shaft 24, the first linear module 204 drives the picking claw 201 to move along the three-axis direction to the winding shaft 24. The picking claw 201 picks up the ball of fiberglass yarn 27, and the first linear module 204 transfers the ball of fiberglass yarn 27 into the pre-placed test cups 203 on the picking tray 202. The second linear module 205 drives the picking tray 202 to move in a linear direction, transporting the test cups 203 filled with the fiberglass yarn 27 to the loading positions (there are two loading positions in total), waiting for the testing personnel to pick them up. When all the test cups 203 are filled with samples, the staff removes the samples, and the second linear module 205 rearranges the empty test cups 203, waiting for the next round of sampling.

[0039] Reference Figure 3 and Figure 6 In this embodiment of the application, a mounting plate 26 is also included. The mounting plate 26 is disposed on the first linear module 204. The picking claw 201 is disposed on the mounting plate 26. The picking claw 201 includes a clamping plate 2011, a rotating rod 2012 and a rotating component. The clamping plate 2011 is fixedly disposed on the mounting plate 26. There are two rotating rods 2012, both of which are rotatably disposed on the clamping plate 2011. The rotating component is used to drive the two rotating rods 2012 to move closer or further away from each other. Reference Figure 3 and Figure 6The rotating component includes a drive rod 2013, a connecting plate 2014, a mounting shaft 2015, and a hinge shaft 2016. The end of the drive rod 2013 is provided with a mounting notch 10. There are two rotating rods 2012. The connecting plate 2014 is fixedly installed inside the rotating rod 2012 and is rotatably installed in the mounting notch 10 through the mounting shaft 2015. The rotating rod 2012 is rotatably installed on the clamping plate 2011 through the hinge shaft 2016. The drive rod 2013 is slidably installed on the clamping plate 2011. Reference Figure 3 and Figure 6 Furthermore, the drive rod 2013 is slidably disposed within the clamping plate 2011, and the drive rod 2013 slides along the length direction parallel to the clamping plate 2011. A second electric cylinder for driving the drive rod 2013 to slide is disposed within the clamping plate 2011.

[0040] After the fiberglass yarn 27 is wound into a ball on the winding shaft 24, the picking claw 201 is driven to the winding group by the first linear module 204 and is directly opposite the receiving notch 12 of the winding shaft 24. At this time, the two rotating rods 2012 are close to each other and in a retracted state. Then the second electric cylinder is activated, which drives the drive rod 2013 to slide. The sliding of the drive rod 2013 drives the connecting plate 2014 and the rotating rod 2012 to rotate, thereby causing the rotating rod 2012 to rotate out of the gripper. During the rotation of the rotating rod 2012, the wound fiberglass yarn 27 is transferred from the yarn ball on the winding shaft to the rotating rod 2012, and then the yarn ball is transferred to the detection cup 203 by the rotating rod 2012. The operation is simple and convenient.

[0041] The implementation principle of a glass fiber yarn ball fixed weight and fixed length sampling device according to an embodiment of the present invention is as follows: In fixed-length sampling mode, the operator passes the fiberglass yarn 27 through the fixed gripper A221 and the movable gripper 222. The movable gripper 222 clamps the yarn, and the fixed gripper A221 releases the yarn. The second drive unit drives the movable gripper 222 to move along the length of the sampling plate 21, causing the yarn to unwind from the yarn roll. When the movable gripper 222 moves to a set distance (corresponding to the required yarn length), the fixed gripper A221 clamps the yarn. At this time, the yarn is simultaneously held and fixed in two positions by the fixed gripper A221 and the movable gripper 222. The pneumatic shears 2231 cuts the yarn near the fixed gripper A221, and the first drive unit drives the winding shaft 24 to rotate and wind the cut yarn into a ball.

[0042] In constant-weight sampling mode, 27 rolls of fiberglass yarn are placed on the weighing device, with the yarn passing through fixed gripper A221 and movable gripper 222. Movable gripper 222 clamps the yarn, fixed gripper A221 releases the yarn, and a second drive unit drives movable gripper 222 to translate, causing the clamping end of the yarn to pass a certain distance past fixed gripper B231. Fixed gripper B231 extends to clamp the yarn, and movable gripper 222 returns to its original position. Fixed gripper B231 releases the yarn, and winding shaft 24 begins winding the yarn under the drive of servo motor 16. The weighing device monitors the weight change of the 27 rolls of fiberglass yarn in real time. When the weight reduction reaches the set constant-weight requirement in grams, winding shaft 24 stops rotating, and shearing component 223 cuts the yarn, completing the constant-weight sampling.

[0043] The picking claw 201 is driven to the winding assembly by the first linear module 204 and is directly opposite the receiving notch 12 of the winding shaft 24. At this time, the two rotating rods 2012 are close to each other and in a retracted state. Then, the second electric cylinder is activated, which drives the drive rod 2013 to slide. The sliding of the drive rod 2013 drives the connecting plate 2014 and the rotating rod 2012 to rotate, thereby causing the rotating rod 2012 to rotate out of the gripper. During the rotation of the rotating rod 2012, the wound glass fiber yarn 27 is transferred from the yarn ball on the winding shaft to the rotating rod 2012. Then, the yarn ball is transferred to the detection cup 203 by the rotating rod 2012. Finally, the picking plate 202 and the detection cup 203 are transferred to the loading position by the second linear module 205, so that the operator can easily pick up the sample for relevant testing.
