A support seat is movably installed on the surface of the auxiliary slider away from the support column component. A support bearing is embedded in the middle of the support seat, and an auxiliary bearing seat is embedded in the side of the support seat away from the tension roller component. A fixing bolt is horizontally installed through the interior of the auxiliary bearing seat.

[0007] Furthermore, the support column component includes a column component, a grounding seat, and a support guide rail. The bottom of the column component is connected to the grounding seat, and the support guide rail is vertically mounted on the front surface of the column component.

[0008] Furthermore, the grounding base and the column component are welded together, and the grounding base has holes at each of the four opposite corners for bolt installation.

[0009] Furthermore, the auxiliary slider and the support guide rail are connected and combined with each other using a slotted embedded structure, and the support bearing, auxiliary bearing seat and fixing bolt are all on the same horizontal central axis.

[0010] Furthermore, the tensioning roller component includes a tensioning roller body, an anti-slip sleeve, and a connecting shaft. The surface of the tensioning roller body is tightly fitted with the anti-slip sleeve, and both ends of the tensioning roller body are horizontally provided with connecting shafts.

[0011] Furthermore, the tension roller body and the connecting shaft are integrally structured, and the connecting shaft passes horizontally through the axis of the support bearing and the auxiliary bearing seat, and the fixing bolt is horizontally threaded inside the end of the connecting shaft away from the tension roller body.

[0012] Furthermore, the drive seat component includes a support slider, a positioning bolt, a servo motor, a fixed angle plate, and a transmission shaft. Positioning bolts are symmetrically and horizontally threaded on both sides of the support slider. A servo motor is movably mounted on the surface of the support slider away from the support column component. The fixed angle plate is symmetrically connected to the end of the servo motor near the support slider. The power output end of the servo motor is horizontally mounted on the transmission shaft through a coupling.

[0013] Furthermore, the support slider and the support guide rail are connected and combined with each other using a slotted embedded structure. The servo motor and the fixed angle plate are set as an integral structure, and the servo motor is movably connected and installed to the support slider through the fixed angle plate. The drive shaft is horizontally embedded and installed at one end of the take-up roller. The tension roller component and the take-up roller are parallel to each other.

[0014] This invention provides an adjustable tension bonding yarn winding device, which has the following advantages:

[0015] 1. This utility model, by incorporating a support column component and an adjusting component, enables the entire device to adjust the tension of the bonding yarn. During use, the tensioning roller component applies appropriate tension to the bonding yarn, preventing it from becoming loose or overly tight during winding, thus ensuring winding quality and efficiency. Simultaneously, the design of the adjusting component allows users to fine-tune the position of the tensioning roller component according to actual needs, further improving the flexibility and applicability of the device. Furthermore, the support column component, as the supporting structure of the entire device, not only provides stable support but also, through the cooperation of its support guide rail with auxiliary sliders, support sliders, and other components, enables smooth vertical movement adjustment of the adjusting component and drive seat component. This design not only enhances the device's performance but also... The structural stability of the device also makes it easier and faster for users to adjust the tension of the bonding wire. During adjustment, simply loosen the limit bolts and positioning bolts, and the auxiliary slider and support slider can slide and adjust the vertical position of the adjusting component and drive seat component along the support guide rail. After adjusting to the desired position, tighten the limit bolts and positioning bolts to fix the adjusting component and drive seat component. The operation process is simple and convenient, without complicated operation steps and tools, which greatly saves users' time and energy and improves work efficiency. At the same time, the grounding seat design of the support column component allows the entire device to be placed stably on the ground, avoiding winding quality problems caused by device shaking or tilting, and further ensuring the stability and reliability of the winding operation.

[0016] 2. In this utility model, since the adjusting component is movably installed on the surface of the support column component, the number of adjusting components can be adjusted according to usage needs. This allows for the adjustment and setting of different numbers of tension roller components to meet different winding tension requirements. For example, when a larger winding tension is required, the number of tension roller components can be increased. Through the synergistic effect of multiple tension roller components, the bonding yarn is subjected to more uniform tension during winding, further improving winding quality. Conversely, when a smaller winding tension is required, the number of tension roller components can be reduced to decrease the tension on the bonding yarn and avoid damage or deformation caused by excessive tension. This design not only improves the flexibility and applicability of the device but also allows users to make personalized adjustments according to actual needs, achieving precise control of winding tension. In addition, the structural arrangement between the drive seat component and the winding roller allows the winding roller to be driven by the servo motor. Driven by the servo motor, the device rotates stably to complete the winding of the bonding wire. The servo motor is connected to the drive shaft via a coupling, ensuring stable power transmission. Simultaneously, the design of the fixed angle plate enhances the connection stability between the servo motor and the support slider, preventing loosening or detachment due to vibration or external forces. This further ensures the stability and reliability of the winding operation. During winding, the bonding wire first undergoes tension adjustment by the tension roller components before being wound by the winding roller. By adjusting the position and number of the tension roller components, the tension of the bonding wire can be effectively controlled, preventing problems such as slackness, knotting, or excessive tightness during winding. This ensures the consistency and stability of the winding quality. Furthermore, the entire device features a compact and rational structural design with high precision in the coordination between components. This not only improves the device's working efficiency but also reduces the failure rate and maintenance costs, providing a better user experience for processing operations.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 5As shown, an adjustable tension bonding yarn winding device includes a support column component 1 and an adjusting component 2. The adjusting component 2 is connected and installed on the front surface of the support column component 1, and a tension roller component 3 is horizontally connected and installed in the middle of the adjusting component 2. A drive seat component 4 is connected and installed on the lower front side of the support column component 1, and a winding roller 5 is horizontally connected and installed at one end of the drive seat component 4. The adjusting component 2 includes an auxiliary slider 201, a limit bolt 202, a support seat 203, a support bearing 204, an auxiliary bearing seat 205, and a fixed... The fixed bolt 206 and the auxiliary slider 201 are symmetrically and horizontally threaded with limit bolts 202 on both sides. A support seat 203 is movably mounted on the side of the auxiliary slider 201 away from the support column component 1. A support bearing 204 is embedded in the middle of the support seat 203. An auxiliary bearing seat 205 is embedded in the side of the support seat 203 away from the tension roller component 3. A fixing bolt 206 is horizontally installed through the interior of the auxiliary bearing seat 205. The auxiliary slider 201 and the support guide rail 103 are grooved. The embedded structures are interconnected, with the support bearing 204, auxiliary bearing seat 205, and fixing bolt 206 all on the same horizontal central axis. The tension roller component 3 includes a tension roller body 301, an anti-slip sleeve 302, and a connecting shaft 303. The surface of the tension roller body 301 is tightly fitted with the anti-slip sleeve 302, and both ends of the tension roller body 301 are horizontally provided with connecting shafts 303. The tension roller body 301 and the connecting shaft 303 are integrally formed, and the connecting shaft 303 horizontally passes through the support bearing 204, auxiliary bearing seat 205, and fixing bolt 206. At the center of the auxiliary bearing housing 205, and with the fixing bolt 206 horizontally threaded inside the end of the connecting shaft 303 away from the tension roller body 301, during adjustment, only the limit bolt 202 and the positioning bolt 402 need to be loosened. The position of the adjusting component 2 and the drive seat component 4 can be adjusted vertically by the auxiliary slider 201 and the support slider 401 along the support guide rail 103. After adjusting to the required position, the limit bolt 202 and the positioning bolt 402 can be tightened again to fix the adjusting component 2 and the drive seat component 4.

[0025] like Figures 1 to 5As shown, the support column component 1 includes a column component 101, a grounding seat 102, and a support guide rail 103. The bottom of the column component 101 is connected to the grounding seat 102, and the support guide rail 103 is vertically mounted on the front surface of the column component 101. The grounding seat 102 and the column component 101 are welded together, and the grounding seat 102 has holes for bolt installation at its four opposite corners. The drive seat component 4 includes a support slider 401, a positioning bolt 402, a servo motor 403, a fixing angle plate 404, and a drive shaft 405. The positioning bolts 402 are symmetrically and horizontally threaded on both sides of the support slider 401. The servo motor 403 is movably mounted on the surface of the support slider 401 away from the support column component 1, and the fixing angle plate 404 is symmetrically connected to the end of the servo motor 403 near the support slider 401. The power output end of the servo motor 403 is connected to the water-cooled end via a coupling. A drive shaft 405 is mounted horizontally. The support slider 401 and the support guide rail 103 are connected to each other using a slotted embedded structure. The servo motor 403 and the fixed angle plate 404 are integrated into one structure, and the servo motor 403 is movably connected to the support slider 401 through the fixed angle plate 404. The drive shaft 405 is horizontally embedded at one end of the take-up roller 5. The tension roller component 3 and the take-up roller 5 are parallel to each other. When a larger take-up tension is required, the number of tension roller components 3 can be increased. Through the synergistic effect of multiple tension roller components 3, the number of tension roller components 3 can be reduced when a smaller take-up tension is required, so as to reduce the tension on the bonding wire and avoid damage or deformation caused by excessive tension. In addition, the structural arrangement between the drive seat component 4 and the take-up roller 5 allows the take-up roller 5 to rotate stably under the drive of the servo motor 403 to complete the take-up operation of the bonding wire.

[0026] In summary, as Figures 1 to 5 As shown, when using this adjustable tension bonding wire winding device, first place the device in the designated position, and then use bolts to fix the device to the ground through the hole structure on the grounding base 102 to ensure the stability of the device during use.

[0027] Next, according to actual needs, the position of the adjusting component 2 on the support guide rail 103 is adjusted by loosening the limit bolt 202 to determine the appropriate height of the tension roller component 3 connected thereto. After adjusting to the required position, the limit bolt 202 is tightened again to fix the adjusting component 2.

[0028] Similarly, the position of the positioning bolt 402 on the drive seat component 4 on the support guide rail 103 can be changed by adjusting the positioning bolt 402 on the drive seat component 4 to adapt to different winding requirements. Then, one end of the bonding wire is passed through the tension roller component 3 and the winding roller 5 in sequence to ensure that the bonding wire can be smoothly attached to the anti-slip sleeve 302 of the tension roller body 301 and tightly wound on the winding roller 5.

[0029] Next, the servo motor 403, which is mounted on the surface of the support slider 401 using the positioning bolt 402, is started. The servo motor 403 drives the transmission shaft 405 to rotate through the coupling, thereby driving the take-up roller 5 to rotate stably and start the take-up operation. During the take-up process, the adjusting component 2 connected to the tension roller component 3 will work together to provide stable support for the tension roller body 301 through the support bearing 204 and the auxiliary bearing seat 205 according to the tension requirements of the bonding yarn. The fixing bolt 206 ensures the firm connection of the connecting shaft 303, so as to avoid shaking or displacement during the take-up process and affect the take-up quality.

[0030] Meanwhile, the anti-slip sleeve 302 design enhances the friction between the tension roller body 301 and the bonding wire, allowing the bonding wire to be more stably subjected to tension when passing through the tension roller component 3, further improving the stability and reliability of winding. Throughout the winding process, users can adjust the positions of the adjusting component 2 and the drive seat component 4, as well as increase or decrease the number of tension roller components 3, to achieve precise control of the bonding wire tension, thereby meeting different winding requirements. In addition, the device has a compact and reasonable structural design, which not only improves work efficiency but also reduces the failure rate and maintenance costs, bringing a better user experience.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
