Description

Technical Field

[0001] This invention relates to the field of sewing thread production technology, and in particular to a color pattern card winding device and winding method. Background Technology

[0002] like Figure 1 As shown, this is a color pattern card 9 for sewing thread, which is a long strip of cardboard. Each color pattern card 9 has multiple equally spaced grooves 901, and a sample bundle of sewing thread 902 is wound around each groove 901. The sample bundle of sewing thread 902 needs to be wound at least 20 times to avoid appearing too thin. In the product sample booklets used for promotion, at least five color pattern cards 9 are pasted on each page, so the workload of making these color pattern cards 9 is not small.

[0003] Currently, these color sample cards are often made manually, one by one, which is time-consuming and labor-intensive. The number of turns wound in each groove 901 is inconsistent, and the tightness may also vary. Even under conditions of fatigue, there is a tendency to repeatedly wind the same color.

[0004] To overcome the above problems, a color code template card winding device is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a winding device for color pattern cards, which replaces manual winding of individual cards and improves the production efficiency and quality of color pattern cards.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a color code template card winding device for winding long strip-shaped color code template cards, comprising a frame, a wire feeding assembly, a wire guiding mechanism, a cycloidal assembly, and a wire take-up assembly. The thread feeding assembly is located at the right end of the frame and is equipped with multiple positioning shafts for placing sewing thread spools; the thread guide mechanism is located at the top of the frame and can individually guide each sewing thread to the cycloidal assembly; the cycloidal assembly is arranged parallel to the color pattern card held by the take-up assembly, and the cycloidal assembly can reciprocate along the length direction while guiding the thread. The take-up assembly includes an active locking shaft and a passive locking shaft that rotate synchronously on the same axis, and the two ends of the color sample card are respectively attached to the shaft ends of the active locking shaft and the passive locking shaft.

[0007] The applicant has long been engaged in the production and manufacturing of sewing thread, and requires a large number of sample books for promotion and product introduction at exhibitions, customer visits, and other occasions. Therefore, a large number of color sample cards need to be produced. Manual winding is extremely time-consuming and labor-intensive, and the winding quality is inconsistent, which negatively impacts the customer experience. Therefore, the applicant decided to develop a winding device for the color sample cards. Currently, the device is in normal use and performing well.

[0008] Furthermore, the wire guiding mechanism includes a primary wire guiding assembly, a secondary wire guiding assembly, and a tertiary wire guiding assembly. The primary wire guiding assembly is located at the top of the right end of the frame and above the thread feeding assembly. The primary wire guiding assembly includes multiple first wire guide rings, which are fixed to crossbars. The two ends of the crossbars are welded to the extension frame at the right end of the frame. There are multiple crossbars, which are arranged in parallel and staggered left and right. Each first wire guide ring guides one sewing thread, corresponding to one sewing thread spool. The primary wire guiding assembly outputs a single thread to the secondary and tertiary wire guiding assemblies and then to the cycloidal wire assembly.

[0009] Furthermore, the secondary guide wire assembly includes multiple guide wire wheels, which are mounted on a cross brace at the top of the frame. A single sewing thread is fed backward after passing around the guide wire wheel several times. A second guide wire loop for auxiliary guide wires is also provided in front of the guide wire wheel.

[0010] Furthermore, the take-up assembly also includes a crank handle, gears, and a synchronous shaft. The synchronous shaft is arranged parallel to the drive shaft and the driven shaft directly below them, and its two ends are supported on the frame by bearing seats. The two ends of the synchronous shaft are respectively connected to the drive shaft and the driven shaft by a pair of interlocking gears. The root of the crank handle is coaxially fixedly connected to the outer end of the drive shaft.

[0011] Furthermore, the active locking shaft has a U-shaped groove centered on its inner end, and a threaded hole is centered on one side wall of the U-shaped groove. A clamping screw is threaded into the threaded hole, and the inner end of the clamping screw can clamp the end of the color sample card inserted into the U-shaped groove. The inner end of the passive locking shaft has the same structure as the active locking shaft.

[0012] Furthermore, the cycloidal assembly includes a crossbeam and guide blocks. The top surface of the frame is provided with guide seats at both ends of the crossbeam, and the two ends of the crossbeam are slidably connected to the guide seats. Multiple guide blocks are arranged at equal intervals on the crossbeam and can individually guide the sewing thread.

[0013] Furthermore, it also includes a transmission assembly, which is tractively connected between the active locking shaft and the crossbeam, and is capable of driving the crossbeam to reciprocate along the guide direction of the guide seat.

[0014] Furthermore, the transmission assembly includes an intermediate shaft, a first large pulley, a second small pulley, a second large pulley, and an eccentric cam. The intermediate shaft is horizontally mounted on the top surface of the frame at the right position via a bearing seat. The first large pulley and the second small pulley are coaxially arranged and connected to the intermediate shaft via a flat key. The first large pulley is belt-connected to the first small pulley on the drive shaft. The second large pulley is vertically rotatably arranged below the crossbeam. The eccentric cam is coaxially arranged on the top surface of the second large pulley. The second large pulley is belt-driven to the second small pulley. The bottom surface of the crossbeam is provided with a baffle assembly adapted to the eccentric cam. Two sets of baffle assemblies are symmetrically arranged on the front and rear sides of the eccentric cam.

[0015] Furthermore, the baffle assembly includes a baffle, a threaded rod, and a locking nut. The crossbeam is specifically made of angle steel, and a waist-shaped hole is opened on the top plate of the crossbeam along the length direction. The baffle is also made of a section of angle steel and the threaded rod is fixedly connected to the top surface. The threaded rod passes through the waist-shaped hole and is locked with the locking nut. The vertical panel of the baffle contacts the side wall of the eccentric cam.

[0016] The application of the active locking shaft to drive the reciprocating movement of the crossbeam is an important improvement made by the applicant based on the actual situation. This ensures that the winding and cycloidal movements are coordinated and consistent, resulting in a significant improvement in winding quality.

[0017] This invention also discloses a manufacturing process for a color code template card winding device, which involves winding a color code template card using any of the above-mentioned color code template card winding devices, including the following steps: Step 1, Install the card: Install the white card of the color sample card on the inner end of the active card shaft and the passive card shaft. Insert the end of the color sample card into the U-shaped groove and tighten it with the clamping screw. The color sample card is in a flat state. Step 2, threading: Place the spools of sewing thread to be wound onto the positioning shaft of the thread feeding assembly, the number of which should match the number of thread grooves on the color pattern card; find the thread end, and thread it through the primary guide assembly, secondary guide assembly, tertiary guide assembly and cycloidal assembly in sequence, then manually wind it tightly into the corresponding thread groove. Repeat this process for all other spools. Step 3, winding: Manually rotate the crank handle. Under the transmission of gears and synchronous shafts, the active and passive locking shafts rotate synchronously, carrying the color pattern card around its own long axis to begin winding. At the same time, the first small pulley, the first large pulley, the second small pulley, and the second large pulley of the belt drive cause the eccentric cam to rotate around the vertical central axis. The eccentric cam pushes the vertical panel of the baffle from left to right, causing the cycloidal assembly to move back and forth in a narrow range, so that the sewing thread is evenly wound in the thread groove. Step 4: Cut the thread. After completing the required number of turns, cut the sewing thread on one side of the color pattern card to facilitate the next winding. Loosen the top screw and remove the finished color pattern card. Repeat Step 2 to tighten the thread end and Step 3 to start winding the next color pattern card.

[0018] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention relates to a color pattern card winding device. By incorporating a thread feeding assembly and a guide wire mechanism, it enables the simultaneous and individual feeding of multiple sewing threads without interference. The addition of a cycloidal thread assembly, which moves reciprocally along its length, ensures the sewing thread is evenly wound across the entire width of the thread groove. The coaxially positioned active and passive locking shafts allow for the centered mounting and synchronous rotation of elongated color pattern cards, preventing twisting and breakage. This color pattern card winding device replaces manual winding, improving both the efficiency and quality of color pattern card production.

[0019] Furthermore, by adding a complete set of first guide rings, guide wheels, second guide rings, and guide wire rings, the single sewing thread can be guided effectively throughout its entire journey, preventing adjacent sewing threads from tangling. The addition of guide wheels increases the tension during thread winding, preventing it from becoming too loose and winding onto the color pattern card. The addition of a synchronous shaft and gear set ensures strict synchronization between the active and passive locking shafts during operation, and the color pattern card does not need to transmit torque, preventing breakage. The U-shaped groove and clamping screw facilitate the easy insertion of the color pattern card into the end of the U-shaped groove. A guide seat guides the crossbeam, preventing it from falling off or swinging left and right, ensuring it can only move back and forth. By setting a transmission assembly between the active locking shaft and the crossbeam, the power of the active locking shaft drives the crossbeam, allowing the guide block to swing back and forth while rotating the color pattern card, ensuring the sewing thread is evenly wound onto the thread groove, with both movements coordinated and consistent. The use of two sets of large and small pulleys enables a large reduction ratio, thereby achieving slow reciprocating movement of the crossbeam. The crossbeam directly uses the vertical plate of the angle steel as a guide bar to reciprocate within the through groove of the guide seat, resulting in a simple and easy-to-implement structure. By installing a threaded rod on the baffle through the oblong hole, the position of the baffle can be adjusted, thus allowing for adjustment of the reciprocating movement amplitude.

[0020] The color code template card winding method of the present invention can simultaneously wind all the grooves on a color code template card, which greatly improves the winding efficiency and ensures reliable and consistent winding quality. Attached Figure Description

Detailed Implementation

[0024] The core of this invention is to provide a color pattern card winding device that replaces manual winding of individual color patterns cards, thereby improving the production efficiency and quality of color pattern cards.

[0025] 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 a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] Refer to the attached diagram. Figure 1 A schematic diagram of the main view of an existing sewing thread color pattern card; Figure 2This is a schematic diagram of the main structure of the color code template card winding device of the present invention; Figure 3 This is a top view schematic diagram of the color code template card winding device of the present invention; Figure 4 This is a front view schematic diagram of the take-up assembly in this invention; Figure 5 This is a partial cross-sectional view of the second largest pulley section in this invention.

[0028] In one specific embodiment of the present invention, such as Figures 1 to 5 As shown, the color code template card winding device of the present invention is used to wind long strip-shaped color code template cards 9, including a frame 1, a wire feeding assembly 2, a wire guiding mechanism, a cycloidal assembly 6, and a wire take-up assembly 7. The frame 1 adopts a frame structure formed by welding steel profiles.

[0029] The thread feeding assembly 2 is positioned at the center of the right end face of the frame 1. Multiple positioning shafts for placing sewing thread spools are mounted on the cross brace of the thread feeding assembly 2; that is, the thread spools can be vertically placed on the positioning shafts to output sewing thread upwards. The thread guide mechanism is located at the top of the frame 1 and can individually guide each sewing thread to the cycloidal thread assembly 6. The cycloidal thread assembly 6 is positioned parallel to the color pattern card 9 held by the take-up assembly 7, and can reciprocate along its own length while guiding the thread. The range of movement is adapted to the width of the thread groove 901 on the color pattern card 9.

[0030] The take-up assembly 7 is located at the left end of the top surface of the frame 1. The take-up assembly 7 includes a coaxially rotating active locking shaft 702 and a passive locking shaft 703. The two ends of the color pattern card 9 are respectively attached to the shaft ends of the active locking shaft 702 and the passive locking shaft 703. When the active locking shaft 702 is driven to rotate, it drives the color pattern card 9 to rotate, thereby realizing the take-up and winding action.

[0031] By setting up the thread feeding assembly 2 and the guide wire mechanism, multiple sewing threads can be fed synchronously and individually without interference. By adding the cycloidal thread assembly 6, which moves back and forth along its own length, the sewing thread can be evenly wound onto the entire width of the thread groove 901. The active locking shaft 702 and the passive locking shaft 703, which are set with coaxial openings, can centrally lock the long strip-shaped color pattern card 9 and rotate synchronously, preventing the color pattern card 9 from twisting and breaking. The color pattern card winding device of the present invention replaces manual winding of individual threads, improving the production efficiency and quality of color pattern cards.

[0032] In one specific embodiment of the present invention, such as Figure 2 and Figure 3As shown, the wire guiding mechanism includes a primary wire guiding assembly 3, a secondary wire guiding assembly 4, and a tertiary wire guiding assembly 5. The primary wire guiding assembly 3 is located at the top right end of the frame 1 and above the thread feeding assembly 2. The primary wire guiding assembly 3 includes multiple first wire guide rings 301, which are fixed to crossbars. Multiple first wire guide rings 301 are fixed to each crossbar, and a positioning shaft is located directly below each first wire guide ring 301. Both ends of the crossbars are welded to an extension frame at the right end of the frame 1. The crossbars are multiple and arranged parallel to each other, staggered left and right. Each first wire guide ring 301 guides one sewing thread, corresponding to one sewing thread spool. The primary wire guiding assembly 3 guides a single thread to the secondary wire guiding assembly 4 and the tertiary wire guiding assembly 5, and then to the cycloidal wire assembly 6.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the secondary guide wire assembly 4 includes multiple guide wire wheels 402, which are mounted on cross braces at the top of the frame 1. Multiple cross braces are supported, and each cross brace has multiple guide wire wheels 402. The end faces of the guide wire wheels 402 are horizontally positioned, and a single sewing thread is fed backward after passing around the guide wire wheel 402 several times. A second guide wire ring 401 for auxiliary guide wires is also provided in front of the guide wire wheels 402.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the three-stage conductor assembly 5 includes multiple conductor loops 501, with a single sewing thread passing through the loop hole of the conductor loop 501. The first conductor loop 301, conductor wheel 402, second conductor loop 401, and conductor loop 501 are arranged in a one-to-one correspondence, and each of them is made of steel parts covered with a plastic layer, with a smooth surface and good wear resistance.

[0035] By adding a complete set of first guide ring 301, guide wheel 402, second guide ring 401 and guide wire ring 501, the single sewing thread can be guided well throughout the entire process, avoiding the tangling of adjacent sewing threads; by adding guide wheel 402, the tension of the sewing thread during the winding process can be increased, preventing it from being too loose and winding onto the color pattern card 9.

[0036] In one specific embodiment of the present invention, such as Figures 2 to 4 As shown, the take-up assembly 7 also includes a crank 701, gears 704, and a synchronous shaft 705. The synchronous shaft 705 is arranged parallel to the drive shaft 702 and the driven shaft 703, and its two ends are supported on the frame 1 by bearing seats. The two ends of the synchronous shaft 705 are respectively connected to the drive shaft 702 and the driven shaft 703 via a pair of interlocking gears 704, meaning there are four gears 704. The root of the crank 701 is coaxially fixed to the outer end of the drive shaft 702, which can be achieved by a threaded connection or by direct welding.

[0037] Specifically, such as Figures 2 to 4 As shown, the handle portion of the crank 701 is also fitted with a sleeve, which can rotate relative to the handle spindle for easy gripping by the operator.

[0038] Obviously, the crank 701 can also be replaced by a geared motor, using an electric method to achieve automated winding. Similar simple replacement methods all fall within the protection scope of this invention.

[0039] Specifically, such as Figures 2 to 4 As shown, the active retaining shaft 702 has a U-shaped groove centered on its inner end. A threaded hole is centrally located on one side wall of the U-shaped groove, and a clamping screw 706 is threaded into the threaded hole. The inner end of the clamping screw 706 clamps the end of the color sample card 9 inserted into the U-shaped groove. The inner end of the clamping screw 706 is flat. The passive retaining shaft 703 has the same structure as the active retaining shaft 702, also featuring the U-shaped groove and the clamping screw 706.

[0040] By adding a synchronous shaft 705 and a gear 704 pair, the active locking shaft 702 and the passive locking shaft 703 are strictly synchronized during operation, and the color sample card 9 does not need to transmit torque, so it will not break. By opening a U-shaped groove and equipping it with a clamping screw 706, the color sample card 9 can be easily inserted into the end of the U-shaped groove.

[0041] Obviously, a coaxial dovetail clamp can also be provided at the inner end of the active locking shaft 702, using a torsion spring as the clamping power source. Only a secure installation of the dovetail clamp is required. Similar simple replacement methods all fall within the protection scope of this invention.

[0042] In one specific embodiment of the present invention, such as Figures 2 to 4 As shown, the cycloidal thread assembly 6 includes a crossbeam and guide blocks 601. Guide seats 101 are respectively provided at both ends of the crossbeam on the top surface of the frame 1, and the two ends of the crossbeam are slidably connected to the guide seats 101. Multiple guide blocks 601 are evenly spaced on the crossbeam and can individually guide the sewing thread.

[0043] Specifically, the wire block 601 is made of plastic column, and a straight guide groove is opened at the top of the plastic column. A single sewing thread passes through the guide groove and then folds down into the color pattern card 9.

[0044] The guide seat 101 guides the crossbeam to prevent it from falling off or swinging left and right, so that it can only move back and forth.

[0045] In one specific embodiment of the present invention, such as Figures 2 to 5As shown, the color code template card winding device of the present invention also includes a transmission component 8, which is connected between the active card shaft 702 and the crossbeam, and can drive the crossbeam to reciprocate along the guide direction of the guide seat 101.

[0046] By setting the transmission component 8 between the active locking shaft 702 and the crossbeam, the crossbeam is driven by the power of the active locking shaft 702, which enables the wire block 601 to swing back and forth while rotating the color pattern card 9, so that the sewing thread is evenly wound onto the thread groove 901, and the two movements are coordinated and consistent.

[0047] Specifically, such as Figures 2 to 5 As shown, the transmission assembly 8 includes an intermediate shaft, a first large pulley 801, a second small pulley 802, a second large pulley 803, and an eccentric cam 804. The intermediate shaft is horizontally mounted on the top surface of the frame 1, slightly to the right, via a bearing seat. The first large pulley 801 and the second small pulley 802 are coaxially arranged and connected to the intermediate shaft via a key. The first large pulley 801 is belt-driven to the first small pulley 707 on the drive shaft 702. The second large pulley 803 is vertically rotatably mounted below the crossbeam. The eccentric cam 804 is coaxially mounted on the top surface of the second large pulley 803, and the second large pulley 803 is belt-driven to the second small pulley 802. The bottom surface of the crossbeam is provided with a baffle assembly adapted to the eccentric cam 804, and two sets of baffle assemblies are symmetrically arranged on the front and rear sides of the eccentric cam 804.

[0048] By employing two sets of large and small pulleys, a large reduction ratio can be achieved, thereby enabling the slow reciprocating movement of the crossbeam.

[0049] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the baffle assembly includes a baffle 603, a threaded rod 604, and a locking nut. The crossbeam is specifically made of angle steel, and the guide seat 101 is a square tube with a vertical through groove on its top surface. The vertical plate of the crossbeam is slidably connected in the through groove. A waist-shaped hole 602 is formed along the length of the top plate of the crossbeam. The baffle 603 is also made of a section of angle steel and the threaded rod 604 is fixedly connected to its top surface by welding. The threaded rod 604 passes through the waist-shaped hole 602 and is locked in place by the locking nut. The vertical plate of the baffle 603 contacts the side wall of the eccentric cam 804.

[0050] The crossbeam directly uses the vertical plate of the angle steel as a guide bar to reciprocate in the through groove of the guide seat 101, which is simple and easy to implement; by installing the threaded rod 604 on the baffle 603 through the waist-shaped hole 602, the position of the baffle 603 can be adjusted, and the reciprocating movement range can be adjusted.

[0051] Obviously, the crossbeam can also be made of a rectangular tube, with a rectangular hole centrally located on the guide seat 101 as a guide hole, which can also serve as a guide and prevent rotation. Similar simple substitutions all fall within the protection scope of this invention.

[0052] In summary, the color pattern card winding device of the present invention, by setting up the thread feeding component 2 and the guide wire mechanism, can simultaneously and individually guide multiple sewing threads without interference. By adding the cycloidal component 6, which moves back and forth along its own length, the sewing thread can be evenly wound onto the entire width of the thread groove 901. The active locking shaft 702 and the passive locking shaft 703, which are set with coaxial openings, can centrally lock the long strip-shaped color pattern card 9 and rotate synchronously, avoiding twisting and breakage of the color pattern card 9. The color pattern card winding device of the present invention replaces manual winding, improving the production efficiency and quality of color pattern cards. Furthermore, by adding a complete set of first guide ring 301, guide wheel 402, second guide ring 401, and guide wire ring 501, the single sewing thread can be better guided throughout the entire process, preventing adjacent sewing threads from tangling. Adding the guide wheel 402 increases the tension during the thread winding process, preventing it from becoming too loose and winding onto the color pattern card 9. Adding a synchronous shaft 705 and gear 704 pair ensures strict synchronization between the active locking shaft 702 and the passive locking shaft 703 during operation, and the color pattern card 9 does not need to transmit torque, preventing breakage. The U-shaped groove and the clamping screw 706 facilitate the insertion of the color pattern card 9 into the end of the U-shaped groove. The guide seat 101 guides the crossbeam, preventing it from falling off or swinging left and right, ensuring it can only move back and forth. By setting the transmission assembly 8 between the active locking shaft 702 and the crossbeam, the crossbeam is driven by the power of the active locking shaft 702, which allows the guide wire block 601 to swing back and forth while rotating the color pattern card 9, so that the sewing thread is evenly wound onto the thread groove 901, and the two movements are coordinated. The use of two sets of large and small pulleys can achieve a large reduction ratio, thereby achieving slow reciprocating movement of the crossbeam. The crossbeam directly uses the vertical plate of the angle steel as a guide bar to move back and forth in the through groove of the guide seat 101, which is simple and easy to implement; by installing the threaded rod 604 on the baffle 603 through the waist-shaped hole 602, the position of the baffle 603 can be adjusted, and the reciprocating movement amplitude can be adjusted.

[0053] The present invention also discloses a method for winding a color sample card, wherein the color sample card 9 is wound using the color sample card winding device of any of the above embodiments, including the following steps: Step 1, Install the card. Install the unwound white card of the color sample card 9 into the inner end of the active card shaft 702 and the passive card shaft 703. Insert the end of the color sample card 9 into the U-shaped groove and tighten it with the clamping screw 706. Note that the color sample card 9 should be flattened.

[0054] Step 2, threading: Place the spools of sewing thread to be wound onto the positioning shaft of the thread feed assembly 2, ensuring the number matches the number of thread grooves 901 on the color pattern card 9. Locate the thread end and thread it sequentially through the primary guide assembly 3, secondary guide assembly 4, tertiary guide assembly 5, and cycloidal thread assembly 6, then manually wind it tightly into the corresponding thread groove 901. Repeat this process for all other spools.

[0055] Step 3, winding: Manually rotate the crank handle 701. Under the transmission of gear 704 and synchronous shaft 705, the active locking shaft 702 and passive locking shaft 703 rotate synchronously, causing the color pattern card 9 to rotate around its own long axis, starting the winding process. Simultaneously, the belt-driven first small pulley 707, first large pulley 801, second small pulley 802, and second large pulley 803 cause the eccentric cam 804 to rotate around its vertical central axis. The eccentric cam 804 pushes the vertical panel of the baffle 603 left and right, causing the cycloidal thread assembly 6 to move back and forth in a narrow range, ensuring the sewing thread is evenly wound in the thread groove 901.

[0056] Step 4: Cut the thread. After completing the number of turns, cut the sewing thread on one side of the color pattern card 9 to facilitate the next winding. Loosen the top screw 706 and remove the finished color pattern card 9. Repeat the above steps 2 (tightening the thread end) and 3 (starting the winding of the next color pattern card 9).

[0057] The winding method of the color sample card of the present invention can simultaneously wind all the grooves 901 on a color sample card 9, which greatly improves the winding efficiency and ensures reliable and consistent winding quality.

For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
