Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a terminal strip tensioning mechanism. Background Technology

[0002] In the electronics manufacturing industry, terminal strips are key raw materials for producing connector terminals. They are usually made of metal strips such as copper alloys and stainless steel through precision stamping and forming processes, and exist in the form of continuous rolls. This greatly adapts to the high-speed processing requirements of automated production lines and is widely used in connector manufacturing in industries such as automobiles, consumer electronics, and communication equipment.

[0003] However, most automated terminal strip production systems currently suffer from technical shortcomings in high-speed transportation, generally lacking dedicated tensioning mechanisms. During high-speed operation, the lack of effective tension control easily leads to insufficient tension in the terminal strip, causing slippage, misalignment, and other problems. This results in terminal pin spacing errors exceeding process standards, making it difficult to guarantee processing accuracy. This situation not only significantly reduces product yield but also increases material waste and equipment debugging costs during production, becoming a key bottleneck restricting the high-quality and high-efficiency production of electronic connectors. To address this, we propose a terminal strip tensioning mechanism. Summary of the Invention

[0004] The purpose of this utility model is to provide a terminal strip tensioning mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terminal strip tensioning mechanism, comprising a mounting plate, on the side of which two sets of auxiliary wheels and one set of tensioning wheels are movably mounted, with the tensioning wheel located between the two sets of auxiliary wheels; an N-shaped plate is fixedly mounted on the other side of the mounting plate, and a drive motor is fixedly mounted on the surface of the N-shaped plate; connecting shafts are fixedly mounted on the sides of both sets of auxiliary wheels, and both sets of connecting shafts penetrate the mounting plate; a connecting belt is drivingly connected between the two sets of connecting shafts; the output shaft of the drive motor is fixedly connected to one set of connecting shafts; a rectangular groove is formed on the other side of the mounting plate, penetrating the mounting plate; a fixing rod is fixedly mounted inside the rectangular groove; a sleeve block is movably mounted on the surface of the fixing rod, and the sleeve block is movably connected to the tensioning wheel; two sets of pull rods are fixedly mounted on the bottom of the sleeve block, penetrating the mounting plate; handles are fixedly mounted on the bottom of the two sets of pull rods; and a spring is wound between the sleeve block and the rectangular groove.

[0006] As a further embodiment of this utility model: two sets of fixing blocks are fixedly installed on the side of the mounting plate, and a long plate is movably installed inside each of the two sets of fixing blocks. A long groove is opened on the side of the long plate and the long groove penetrates the long plate. A tension plate is movably installed inside the long groove and the tension plate penetrates the bottom of the long plate. A support plate is provided at the bottom of the tension plate. A circular groove is opened on the surface of the long plate and the circular groove penetrates the long plate and the tension plate. A pin is engaged inside the circular groove.

[0007] As a further embodiment of this utility model: two sets of support legs are fixedly installed at the bottom of the mounting plate, and a base is fixedly installed at the bottom of each set of support legs.

[0008] As a further embodiment of this utility model: a motor protective cover is provided on the surface of the N-type plate, the drive motor is located inside the motor protective cover, and heat dissipation holes are provided on the surface of the motor protective cover.

[0009] As a further embodiment of this utility model: the inner diameter of the circular groove is equal to the outer diameter of the protrusion at the front end of the pin.

[0010] As a further embodiment of this utility model: the mounting plate is made of stainless steel, and all the corners of the mounting plate are rounded.

[0011] As a further embodiment of this utility model: a sliding groove is provided on the inner wall of the rectangular groove, and a slider is movably installed inside the sliding groove, and the slider is fixedly connected to the sleeve block.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model involves removing the pin and pulling out the stretching plate, allowing the support plate to contact the ground and support the mounting plate. The pin is then engaged inside the circular groove to limit the stretching plate. The operator then pulls the handle downwards, causing the sleeve block to move downwards and compress the spring. Simultaneously, the tension wheel moves downwards, stretching the terminal strip on its surface until it is taut. This device utilizes constant tension control to ensure the strip is transported smoothly at a constant speed and along a straight trajectory, minimizing the dimensional consistency error of each terminal and preventing processing deviations caused by strip slack. Furthermore, this device limits the tension within the material's elastic deformation range, preventing plastic deformation from affecting the terminal's mechanical properties and reducing strip stretching deformation.

[0014] 2. This utility model fixes the stretching plate by removing the pin, pulling the stretching plate downward to make the support plate contact the ground, and then re-engaging the pin inside the circular groove. This device prevents the material belt from shifting due to equipment shaking, ensuring that the material belt always runs accurately along the preset track during the conveying process, thereby reducing dimensional errors caused by material belt shaking, improving product accuracy, strengthening support and improving stability, reducing impact load between components, extending the service life of components, and reducing downtime maintenance time and replacement costs caused by component damage.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the appendix Figure 1 -Appendix Figure 5 This utility model provides a terminal strip tensioning mechanism, including a mounting plate 1. Two sets of auxiliary wheels 2 and a set of tensioning wheels 3 are movably mounted on the side of the mounting plate 1, with the tensioning wheels 3 located between the two sets of auxiliary wheels 2. An N-shaped plate 4 is fixedly mounted on the other side of the mounting plate 1, and a drive motor 7 is fixedly mounted on the surface of the N-shaped plate 4. Connecting shafts 5 are fixedly mounted on the sides of both sets of auxiliary wheels 2, and both sets of connecting shafts 5 penetrate the mounting plate 1. A connecting belt 6 is connected between the two sets of connecting shafts 5. The output shaft of the drive motor 7... A set of connecting shafts 5 are fixedly connected. A rectangular groove 8 is opened on the other side of the mounting plate 1 and the rectangular groove 8 passes through the mounting plate 1. A fixing rod 9 is fixedly installed inside the rectangular groove 8. A sleeve block 10 is movably installed on the surface of the fixing rod 9 and is movably connected to the tension wheel 3. Two sets of pull rods 11 are fixedly installed at the bottom of the sleeve block 10 and pass through the mounting plate 1. A handle 13 is fixedly installed at the bottom of the two sets of pull rods 11. A spring 12 is wound between the sleeve block 10 and the rectangular groove 8.

[0025] The above solution utilizes constant tension control to ensure that the material strip is transported smoothly at a constant speed and along a straight trajectory, keeping the dimensional consistency error of each terminal within a small range. This avoids processing deviations caused by material strip slack. At the same time, this device limits the tension within the elastic deformation range of the material, preventing plastic deformation from affecting the mechanical properties of the terminals, thereby reducing material strip tensile deformation.

[0026] like Figure 5 As shown, two sets of fixing blocks 14 are fixedly installed on the side of the mounting plate 1, and a long plate 15 is movably installed inside the two sets of fixing blocks 14. A long groove 16 is opened on the side of the long plate 15 and the long groove 16 passes through the long plate 15. A tension plate 18 is movably installed inside the long groove 16 and passes through the bottom of the long plate 15. A support plate 19 is provided at the bottom of the tension plate 18. A circular groove 17 is opened on the surface of the long plate 15 and passes through the long plate 15 and the tension plate 18. A pin 20 is engaged inside the circular groove 17.

[0027] The above solution involves removing the pin 20, pulling down the stretching plate 18 to make the support plate 19 contact the ground, and then re-engaging the pin 20 into the circular groove 17 to fix the stretching plate 18. This device prevents the material belt from shifting due to equipment shaking, ensuring that the material belt always runs accurately along the preset track during the conveying process. This reduces dimensional errors caused by material belt shaking, improves product accuracy, strengthens support and improves stability, reduces impact loads between components, extends the service life of components, and reduces downtime maintenance time and replacement costs caused by component damage.

[0028] like Figure 1As shown, two sets of support legs 25 are fixedly installed on the bottom of the mounting plate 1, and a base 26 is fixedly installed on the bottom of each set of support legs 25.

[0029] The above solution involves fixing two sets of support legs 25 to the bottom of the mounting plate 1, with a base 26 fixedly installed at the bottom of each set of support legs 25. This distributes the weight of the device and improves its stability during operation.

[0030] like Figure 2 As shown, the surface of the N-type plate 4 is provided with a motor protective cover 23, the drive motor 7 is located inside the motor protective cover 23, and the surface of the motor protective cover 23 is provided with heat dissipation holes 24.

[0031] The above solution is adopted: by setting a motor protective cover 23 on the surface of the N-type plate 4, and the drive motor 7 is located inside the motor protective cover 23, the drive motor 7 can be protected from damage caused by collision. Heat dissipation holes 24 are opened on the surface of the motor protective cover 23 to improve the heat dissipation of the drive motor 7.

[0032] like Figure 5 As shown, the inner diameter of the circular groove 17 is equal to the outer diameter of the front protrusion of the pin 20;

[0033] The above solution is adopted: by setting the inner diameter of the circular groove 17 to be equal to the outer diameter of the front protrusion of the pin 20, the pin 20 is made more stable inside the circular groove 17.

[0034] like Figure 1 As shown, mounting plate 1 is made of stainless steel, and all corners of mounting plate 1 are rounded.

[0035] The above solution is adopted: by making the mounting plate 1 out of stainless steel, which has high strength and good rust resistance, and by setting the corners of the mounting plate 1 to be rounded, the aesthetics of the device are improved.

[0036] like Figure 3 As shown, a sliding groove 21 is provided on the inner wall of the rectangular groove 8, and a slider 22 is movably installed inside the sliding groove 21, and the slider 22 is fixedly connected to the sleeve block 10.

[0037] The above solution is adopted: a sliding groove 21 is provided on the inner wall of the rectangular groove 8, and a slider 22 is movably installed inside the sliding groove 21. The slider 22 is fixedly connected to the sleeve block 10, thereby making the sleeve block 10 more stable when sliding on the surface of the fixed rod 9.

[0038] Working principle:

[0039] In use, the operator moves the device to the work site, then removes the pin 20 and pulls the tension plate 18 downward to the appropriate position so that the support plate 19 contacts the ground, thereby supporting the mounting plate 1. Then, the pin 20 is re-engaged into the inside of the circular groove 17 to fix the socket block 10. The operator then wraps the terminal strip around the surface of the auxiliary wheel 2 and the tension wheel 3. Then, the operator pulls the handle 13, causing the socket block 10 on the surface of the fixing rod 9 to move downward. At the same time, the pressure of the socket block 10 applies pressure to the spring 12, causing the spring 12 to be in a compressed state. Simultaneously, as the socket block 10 moves downward, it drives the tension wheel 3 to move downward, thereby stretching the terminal strip on the surface of the tension wheel 3 downward, ensuring that the terminal strip is always taut.
